The Rise of Acrobatic Gymnastics and Associated Injury Risks
Acrobatic gymnastics has seen a significant surge in popularity in recent years. This growing interest has brought with it an increase in related injuries, highlighting the need for effective preventive measures. Acrobatic sports demand exceptional body control across various positions, both on the ground and in the air, requiring a diverse set of motor skills.
Gymnastic performance is closely tied to jumping capacity, particularly in floor and jumping routines. The sport involves demanding footwork on multiple surfaces, including hardwood floors, gymnastics mats, and trampolines. This variety of surfaces adds complexity to the athletes’ training and performance requirements.
Key Factors in Gymnastic Performance
- Body control in multiple positions
- Jumping capacity
- Adaptability to various surfaces
- Coordination of segmental movements
Understanding Muscle Fatigue and Its Impact on Performance
Muscle fatigue plays a crucial role in gymnastic performance and injury risk. It is defined as an exercise-induced reduction in maximal voluntary muscle force, which can occur due to peripheral changes at the muscle level or within the central nervous system. Fatigue can be reversed with rest, but its effects during training and competition can be significant.
During training and competition, gymnasts perform numerous jumps involving the stretch-shortening cycle (SSC) of muscles. This repetitive action often results in acute muscle fatigue in the legs, potentially affecting performance and increasing injury risk.
How is muscle fatigue evaluated?
Muscle fatigue can be assessed by quantifying several factors:
- Maximal voluntary force
- Maximal voluntary shortening velocity
- Power output
The height of a vertical jump, particularly in the countermovement jump (CMJ), is commonly used to evaluate leg muscular power and detect neuromuscular fatigue. This method has been employed in numerous studies investigating recovery time after fatigue interventions.
The Role of Post-Activation Potentiation in Gymnastics
Post-activation potentiation (PAP) is a phenomenon that can significantly enhance muscular power as a result of previous muscular work. It is induced by a voluntary contraction, which serves as a conditioning activity. In the context of gymnastics, understanding PAP is crucial for optimizing performance and training strategies.
It’s important to note that after a conditioning activity, the mechanisms of muscular fatigue and PAP coexist. Consequently, subsequent power output and performance depend on the balance between these two factors. Gymnasts who can recover more efficiently between a series of skills are more likely to sustain a higher level of performance and reduce their risk of injury through fatigue.
Post-Activation Performance Enhancement (PAPE)
While PAP is largely explained by increased myosin light chain phosphorylation occurring in type II muscle fibers, there’s another phenomenon called post-activation performance enhancement (PAPE). PAPE can cause voluntary force enhancement through changes in muscle temperature, muscle/cellular water content, and muscle activation. Understanding the distinction between PAP and PAPE can provide valuable insights for coaches and athletes in optimizing training and performance strategies.
Vertical Insoles: A Game-Changer in Acrobatic Gymnastics
Vertical insoles have emerged as a potential game-changer in acrobatic gymnastics, offering benefits in both performance enhancement and injury prevention. These innovative insoles, such as the Vertical Insoles Achilles Shield Sport, are designed to provide support and improve biomechanics during high-impact activities.
How do vertical insoles benefit gymnasts?
- Improved shock absorption
- Enhanced stability during landings
- Better weight distribution
- Reduced stress on the Achilles tendon
- Potential for improved jumping performance
By incorporating vertical insoles into their training and competition routines, gymnasts may be able to mitigate some of the risks associated with the high-impact nature of their sport while potentially enhancing their performance capabilities.
Instrumented Insoles: A New Frontier in Performance Monitoring
The development of instrumented insoles, such as the ECnsole used in recent studies, represents a significant advancement in performance monitoring for acrobatic gymnastics. These innovative devices allow for real-time measurement of jumping parameters during regular training sessions in the athletes’ natural training environment.
What data can instrumented insoles provide?
Instrumented insoles can offer valuable insights into various aspects of a gymnast’s performance:
- Jump height
- Ground reaction forces
- Contact time
- Flight time
- Power output
This data can help coaches and athletes analyze muscular fatigue, track performance improvements, and optimize training strategies. The ability to collect this information in real-time during actual training sessions provides a more accurate picture of an athlete’s capabilities and limitations compared to isolated testing scenarios.
Pilot Study: Evaluating the Effects of Muscular Fatigue on Vertical Jump Performance
A recent pilot study utilized instrumented insoles to investigate the acute effects of muscular fatigue on vertical jump performance in acrobatic gymnasts. The study involved twelve volunteers who performed a jumping protocol under three conditions: rest, fatigue-induced, and recovery. The testing was conducted on a tumbling surface to simulate real training conditions.
Key findings of the study
The results of the study provided valuable insights into the relationship between muscular fatigue and jumping performance:
- Acrobatic gymnasts showed an inability to effectively use the stretch-shortening cycle for improving vertical jumping performance after the fatigue condition.
- Interestingly, no significant deterioration of jump performance was observed despite the induced fatigue.
- The study demonstrated the potential of instrumented insoles in providing accurate and relevant data in a gymnastics-specific setting.
These findings highlight the complex interplay between muscular fatigue, post-activation potentiation, and performance in acrobatic gymnastics. They also underscore the potential value of using instrumented insoles for ongoing performance monitoring and fatigue management in training programs.
Implications for Training and Injury Prevention in Acrobatic Gymnastics
The insights gained from studies on muscular fatigue, vertical jump performance, and the use of instrumented insoles have significant implications for training methodologies and injury prevention strategies in acrobatic gymnastics.
How can coaches utilize this information?
Coaches can leverage these findings to optimize training programs and reduce injury risks:
- Implement regular fatigue monitoring using vertical jump tests with instrumented insoles
- Adjust training intensity and volume based on individual fatigue levels
- Incorporate proper rest and recovery periods to balance fatigue and post-activation potentiation
- Utilize vertical insoles during training and competition to provide additional support and potentially enhance performance
- Develop targeted strength and conditioning programs to improve fatigue resistance
By integrating these strategies, coaches can help athletes maintain higher levels of performance while minimizing the risk of fatigue-related injuries.
Future Directions in Acrobatic Gymnastics Research and Technology
The field of acrobatic gymnastics is ripe for further research and technological advancements. The pilot study using instrumented insoles has opened up new avenues for investigation and potential improvements in training methodologies.

By implementing these strategies, coaches and sports organizations can help ensure that the pursuit of athletic excellence does not come at the cost of athlete health and well-being.
The Role of Biomechanics in Optimizing Gymnastic Performance
Biomechanics plays a crucial role in understanding and optimizing gymnastic performance. The study of body movements, particularly in relation to the forces acting upon it, can provide valuable insights for improving technique, preventing injuries, and enhancing overall performance.
How does biomechanical analysis benefit gymnasts?
Biomechanical analysis offers several advantages for gymnasts and their coaches:
- Identification of inefficiencies in movement patterns
- Optimization of technique for specific skills
- Reduction of unnecessary stress on joints and muscles
- Improved understanding of the forces involved in various gymnastic movements
- Development of targeted strength and conditioning programs
By incorporating biomechanical principles into training and performance analysis, gymnasts can work towards maximizing their potential while minimizing the risk of injury.
The Importance of Individualized Training Approaches in Acrobatic Gymnastics
As our understanding of muscle fatigue, post-activation potentiation, and individual physiological responses grows, the importance of individualized training approaches in acrobatic gymnastics becomes increasingly apparent. Each gymnast may respond differently to various training stimuli and recovery protocols, necessitating a personalized approach to optimize performance and reduce injury risk.
What factors should be considered in individualized training?
Several key factors should be taken into account when developing individualized training programs for acrobatic gymnasts:
- Individual fatigue profiles and recovery rates
- Specific strengths and weaknesses in different skills
- Body composition and physiological characteristics
- Training history and injury background
- Personal goals and competitive focus
By tailoring training programs to the unique needs and characteristics of each gymnast, coaches can help athletes achieve their full potential while maintaining optimal health and longevity in the sport.

Acute Effects of Muscular Fatigue on Vertical Jump Performance in Acrobatic Gymnasts, Evaluated by Instrumented Insoles: A Pilot Study
The study of fatigue during training is becoming a very useful tool to avoid possible injuries not only during the training sessions but also during recovery time. Many researches have proved that concepts such as muscular fatigue and postactivation potentiation have a close relationship. With this aim, vertical jump can provide a very important information that can help to analyze the muscular fatigue that happened during this type of activity, mainly if the monitoring system is able to measure jumping parameters during their regular training session in their natural training environment. This study was performed with instrumented insoles called ECnsole. These insoles were tested with a group of twelve volunteers. In a tumbling surface, the participants performed a jumping protocol in three conditions: rest, fatigue-induced, and recovery. Using these validated insoles, the acrobatic gymnasts showed an inability to use the stretch-shortening cycle for improving vertical jumping performance after fatigue condition, although no deterioration of jump performance was found.
1. Introduction
The practice of acrobatic gymnastics is a growing physical activity; consequently, the injuries related are also increasing [1]. Acrobatic sports are characterized by a high level of body control in several positions both on and off the ground, which requires various motor skills [1]. Gymnast performance is related to jumping capacity, especially in floor and jumping routines [2]. Moreover, the gymnastics exercises involve demanding footwork on several surfaces, for example, hardwood floors, gymnastics mats, and trampolines [3].
The jumping performance depends on the coordination of the segmental movements, which is determined by the interaction between the neuromuscular indicators and the net moments that have to be generated around the joints to accomplish the mechanical demands [4]. During training and competition, gymnastics athletes perform a large number of jumps that involve the stretch-shortening cycle (SSC) of muscles, which results in acute muscle fatigue of the legs [2, 5]. Among factors influencing the muscle response are the muscle fatigue and potentiation as well as the recovery process, which are provided by the coaches with a more accurate idea about the muscle condition [2]. The phenomenon “post-activation potentiation” (PAP), induced by a voluntary contraction, as conditioning activity, and indicates to a significantly enhances muscular power as a result of previous muscular work [6, 7]. After a conditioning activity, the mechanisms of muscular fatigue and PAP coexist, and therefore, subsequent power output and performance depend on the balance between these two factors [8]. Although it is necessary to clarify that unlike PAP, changes in muscle temperature, muscle/cellular water content, and muscle activation could cause voluntary force enhancement, which is called as postactivation performance enhancement (PAPE) to distinguish it from PAP, that has been largely explained by an increased myosin light chain phosphorylation occurring in type II muscle fibres [9]. Gymnasts who are able to recover more efficiently between a series of skills are more likely to sustain a higher level of performance and to reduce their risk of injury through fatigue [10].
From a neuromuscular point of view, the fatigue is defined as an exercise-induced reduction in maximal voluntary muscle force and may be due to peripheral changes at the level of the muscle, but also at the level of the central nervous system, rest reverses it [11]. This concept overlooks competing intramuscular mechanisms that potentiate force during strenuous workouts and refers more precisely to a total reduction of performance. Fatigue can be evaluated by quantifying maximal voluntary force, maximal voluntary shortening velocity, or power [11]. The height of a vertical jump, especially in the countermovement jump (CMJ), is commonly used to evaluate the legs muscular power [12] and to detect neuromuscular fatigue [13]. In addition, vertical jump has been used in several studies investigating the recovery time after fatigue interventions; however, further research is needed to elucidate the most relevant variables to analyze fatigue when the vertical jumps are employed [11].
The complexity of gymnastics’ events requires several fitness tests in order to monitor the individual progress, for example, the jumping test [14]. Vertical jump tests are employed to assess neuromuscular function, using a variety of instruments and assessment protocols [15] such as force platform, contact mats, accelerometers, and optical devices. However, although laboratory tests provide a high level of accuracy, a more portable and compact approach could also be very useful to analyze jumping performance in the gymnasts. We are referring to minimally invasive systems capable to provide information from multiple sensors for a more complete assessment of jumping. In fact, the purpose of this investigation was to obtain data that could provide information about acute effects of muscular fatigue on vertical jumping performance in acrobatic gymnasts with the least influence in this performance by using an instrumented insole designed by our research group [12]. The authors hypothesised that an increase of external load would change jumping performance during a typical Bosco protocol [16] in acrobatic gymnasts.
2. Materials and Methods
2.1. Participants
A set of twelve volunteers participated in this study, all of them males (age: years, height: , weight: , and body mass index (BMI): ). All of them were acrobatic and sport gymnasts of Acróbatos Gymnastic Club (Granada, Spain) of different levels (from amateur to elite athletes). They were physically active due to their training sessions which were usually four times per week and in the six months before the study had no history of injury. The study was conducted during the competitive season. Written informed consent was obtained from all participants before starting the study, and the protocol was approved by the University of Granada Ethics Committee and met the requirements of the Declaration of Helsinki and the ethical standards in sports and exercise science research [17].
2.2. Materials and Testing
During the current study, a version of an instrumented insoles previously developed by the research group was used, called ECnsole, shown in Figure 1 [12, 18]. The instrumented insoles contained four pressure sensors Flexiforce A401 (Tekscan, South Boston, MA, USA) located at the big toe, first and fifth metatarsal heads, and the heel. These sensors had a diameter of 25.4 mm and a pressure range from 0 to 111 N. In addition, instrumented insoles contained a digital accelerometer LSM303D (STMicroelectronics, Geneva, Switzerland) placed in the arc of the foot; these sensors are communicated by means of the I2C protocol. The insole had a slim profile of 1 mm; therefore, any possible influence on jumping or any kind of exercise performance is minimized. They are connected to a datalogger unit which is placed at the lower back to permit the athletes to carry out the test properly. The datalogger is a microcontrolled unit that uses a PIC24FJ256GB106 (Microchip Technology Inc., Chandler, AZ, USA) to acquire signal from both analog and digital sensors. The gathered data can be stored into a μSD card or sent them by means of a MiWi® transceiver to a personal computer. The measurement can be started either from remote order or by pressing a button located at the unit. The sampling frequency of the ECnsole system has been improved to reach 330 Hz compared to previous versions. ECnsole system is supplied by one 14500 rechargeable battery. This type of battery provided 1400 mAh at 3.7 V, with the same size as an AA alkaline battery. The autonomy of the system is seven and a half hours. In addition, an application has been developed in MATLAB (MathWorks, Natick, MA, USA) to receive the data from sensors and provided the research a user-friendly interface to analyze and plot data. The instrumented insoles have been already validated to measure vertical high jumps comparing its results to a gold standard [12]. The variables provided by the instrumented insoles were the flight time (in milliseconds), the pressure at jumping and landing instance (in kilopascal), and the accelerometer values (in g). Knowing gravity acceleration, the height jump can be calculated from the flight time [12].
The jumping protocol was performed into the tumbling surface. Tumbling surface is a type of “floor,” which is 25 meters long by 2-meter-wide track consisting of fiberglass rods under two layers of foam mats.
2.3. Procedures
At the beginning of the experiment, participants received comprehensive instructions and learned the proper technique of each jump test. Then, all participants completed ten minutes of warm-up exercises. Typical warm-up consisted of five minutes of low intensity running and five minutes of general exercise (i.e., skipping, leg lifts, lateral running, and front-to-behind arm rotations) and practicing the jump tests at low/moderate intensity. After completing the warm-up, the participants put on the trainers with the ECnsole system. The research group provided the same trainers to all the participants to avoid differences due to the footwear. Moreover, a prior familiarization with the jumping tests according to the protocol described by Bosco was carried out [16].
The experiment comprised three experimental sessions per participant as depicted in the flow chart of Figure 2. In each session, the gymnast had to perform five types of jumps: squat jump (SJ), countermovement jump (CMJ), Abalakov Jump (ABK), drop jump (DJ), and repeated jump (RJ). During SJ performance, the participant starts from a 90° knee-bent position with both hands on the hips. In the CMJ, the participant stands upright also with both hands on the hips, and then a countermovement is performed till it reaches approximately 90° to obtain impulse for jumping execution. In ABK jump, the participant stands with a knee angle of 180°, in this case, he or she can swing the arms back behind the body while the knees are bent at 90°. DJ consists in sinking from a platform elevated 60 cm above the floor, and once the floor is reached, jump energetically and finally absorb the reception. RJ is basically the same preceding that CMJ but repeating as many times as possible during 15 seconds.
The different experimental sessions in which the whole study was divided:
PreTest: after the warm-up, the participant started doing the five jumps already described in this work. Every jump was repeated three times except the RJ. When this session was finished, a training protocol designed to produce fatigue in the low body trunk started. The training consisted of 12 series of 6 forward tucked somersaults, with 10 seconds between somersaults and 2 minutes between series. This protocol was done on the tumbling surface
PostTest: immediately after the training protocol was done, the gymnasts repeated the same 5 types of jumps that in PreTest. Once they finished all the jumps, they rested for 15 minutes
ReTest: this session corresponded to the last repetition of the jumps after the resting time of 15 minutes.
2.4. Statistical Analysis
Data were analysed using SPSS, v.19.0 for Windows (SPSS Inc., Chicago, IL, USA), and the significance level was set at . Descriptive data are reported in terms of means and standard deviations (SD). The differences between jumping performance in the jump protocols were analysed using analysis of variance (ANOVA) of repeated measures, adjusted by the Bonferroni test. Additionally, effect sizes for measurements differences were expressed as Cohen’s d [18]; effect sizes are reported as trivial (<0.2), small (0.2-0.49), medium (0.5-0.79), and large (≥0.8) [19].
3. Results and Discussion
In Figure 3, an example of the data obtained from instrumented insoles by performing one of the ABK jumps has been depicted. The four pressure sensors are plot in the graph. Despite all the sensors were measured during the experimental test, only the big toe sensor was considered into the statistical study because in all jumps performed, it was the last sensor contacting the ground before the jump started and the first sensor in contact with the ground in the landing.
In Figures 4 and 5, no significant differences were found between the tests within each of the jumps for flight times, jump height, and jump accelerations, respectively. However, in accelerations at landing, there is a significant difference between pretest and retest in RJ ( vs. , respectively, , ) (Figure 5). Moreover, there are significant differences in the pressure at jumping instance, between the PreTest and ReTest in the CMJ ( vs. , respectively, , ), in the ABK ( vs. , respectively, , ) and between PreTest and Postest in the RJ ( vs. , respectively, , ) (see Figure 6).
The purpose of this investigation was to collect data in order to determine acute effects of muscular fatigue on vertical jumping performance in acrobatic gymnasts using an instrumented insole under an environment that do not affect both jumping performance and gymnast convenience. The main finding of this study was that muscular fatigue did not show a significant influence on jumping performance in these athletes, only, a significant change in pressure at jumping in RJ was found. In addition, the PAPE phenomenon did not occur. However, a previous study in young gymnasts showed that several condition stimuli induce a PAPE response resulting in an improvement in DJ height in the acute phase of recuperation (15 sec–9 min) [20]. In this regard, in elite gymnasts, one set of 5 tuck jumps during warm-up is not adequate to increase CMJ performance, while 3 sets of 5 tuck jumps result in a relatively large increase in CMJ performance [21]. However, heavy-loaded stimulation results in decreased musculature performance and induces the fatigue effect [22, 23]. Moreover, recovery duration after a heavy-load exercise might influence this balance between PAP and fatigue; also, it seems that PAP depends on individual strength levels, which requires different recovery periods [24]. In a meta-analysis, Jacob et al. noted that PAP was optimal after multiple (vs. single) sets, performed at moderate intensities, and during moderate rest periods lengths (7–10 minutes).
On the other hand, leg stiffness is a relevant property in the performance of running, jumping, and hopping activities [25] and has been reported that SSC fatigue induces changes in knee stiffness and take-off velocity during DJ [26]. The increased stiffness during fatigue can be considered as a way the muscle compensates for the lost contractile performance when it performs the SSC [27] in a way used in the present study. Therefore, the optimally use of leg stiffness could store more elastic energy at landing and produce high levels of concentric force output at jumping, which could reduce the fatigue and increasing jumping performance.
4. Limitations and Conclusions
Although in the current study, there was a reduction in the pressure at jumping in CMJ, ABJ, and RJ and an increase of acceleration at landing in RJ during experimental protocol, leg stiffness could have increased, keeping the jump height unchanged despite fatigue. However, leg stiffness was not registered in the current study. The main limitation in this study was that fatigue levels or internal load were not recorded; future studies should address it. However, the strengths of this study include a population sample of elite acrobatic athletes, and we used a novel device to analyze the Bosco protocol in a real setting.
Therefore, the findings of the current study suggest that the experimental protocol, in relation to loading and recovery, was not effective to induce an imbalance between PAPE and fatigue. From a practical point of view, the employed of an instrumented insole could monitor jumping performance in a portable and compact ecological setting. In conclusion, the acrobatic gymnasts showed an inability to use the SSC for improving vertical jumping performance after fatigue condition, although no deterioration of jump performance was found.

Are there certain insoles that help a child’s vertical?
The science and data are lacking on the effect of insoles on the vertical leap. One study compared the vertical leap of a group of collegiate athletes with regular shoes and then with regular shoes plus insoles. The researchers found that greater insole softness did not improve vertical leap. The study challenged the claim that commercially available insoles can increase vertical jump by at least three inches.
One common way to increase vertical leap is through plyometrics. Plyometric training programs have been found to increase vertical jump height in multiple studies. Despite the large variety of variables in studies, improved vertical jump performance is a consistent outcome after plyometric training. Athletes looking to increase explosiveness and vertical jump, focus on plyometric training to increase the percentage of fast-twitch muscle fibers in key muscle groups. To be effective, plyometrics needs to be performed with high-intensity efforts to recruit the fast-twitch fibers that are crucial to improving the vertical jump.

Abstract
Pressure-measuring insoles can be an attractive tool for measuring ground reaction force (GRF) since they are portable and can record multiple consecutive steps. Several researchers have, however, observed that these insoles are less accurate than instrumented force platforms. To address this issue, the authors identified transfer functions that best described each insole size to enhance the measurements of the vertical component of GRF during walking. GRF data were collected from 29 participants (6/23 male/female, 24.3 ± 6.7 yrs, 70.4 ± 23.9 kg, 1.66 ± 0.11 m) using Medilogic® pressure-measuring insoles and Kistler® force platforms for three walking trials. Participants provided the institutionally approved written consent (IRB #724468). The data from both instruments were preprocessed. A subset of the data was used to train the system identification toolbox (matlab) to identify the coefficients of several candidate transfer functions for each insole size. The resulting transfer functions were compared using all available data for each insole to assess which one modified the insole data to be closer to that of the force platform. All tested transfer functions moved the vertical component of GRF closer to the corresponding force platform data. Each insole size had a specific transfer model that that yielded the best results. Using system identification techniques produced transfer functions that, when using insole data of the vertical component of GRF as input, produced output that is comparable to the corresponding measurement using an instrumented force platform.

Orthopedic insoles from the bone on the big toe
Have you noticed how difficult it has become to find shoes? Favorite model shoes began to press in the area of the first toe, even if you take a larger than necessary size? A “bone” or “bump” appeared in the area of the big toe, causing pain when walking, working around the house, after a long stay on your feet? We will reveal all the secrets so that there are no “white spots” about the “bones” on the big toes.
Let’s understand the reasons
The human foot, the most important organ that performs many functions, the most important of which are: support – thanks to it we maintain an upright position, when moving, the support turns into a sensible function that imparts acceleration to the body when walking, running, jumping.
Fig. Phases of step
The spring function softens the shock when walking due to the arches of the foot (see Fig. 1) The balancing function regulates the posture of a person during movement. And yet, the human foot is a vascular pump that is involved in raising venous blood from the lower extremities to the heart, thereby preventing the development of varicose veins of the lower extremities.
Few people know that even in ancient China, a relationship was discovered between the human foot and its internal organs – reflexogenic zones and acupuncture points are located on the plantar surface of the foot, acting on which it is possible to regulate the work of all internal organs.
What contributes to the dysfunction of the foot, the appearance of its deformities in the form of those very bones, and why do these bones most often appear in women?
Risk factors for problems in the foot
This question could be answered simply – over time, the foot flattens and its functions deteriorate. But behind the seeming simplicity, there is a very important thing that we can influence with you, preventing formidable diseases not only of the foot, but of the whole organism as a whole.So, risk factors and why women?
The main risk factors are:
1. Prolonged static loads. Teachers, doctors, nurses, waitresses, flight attendants, salespeople, factory and factory workers – wherever work on the legs predominates, the foot experiences overload, leading to its flattening and deformation.
2. Changes in hormonal levels – pregnancy, endocrine diseases affect the muscles, ligamentous apparatus of the foot. Muscles and ligaments become more elastic, stretch faster, and the foot spreads out.Also, the subcutaneous fat of the foot becomes thinner, the spring function of the foot decreases, which leads to its overload.
3. Overweight – chronic stress, unbalanced nutrition affects hormonal levels, which leads to excess weight, more often women suffer from such hormonal disorders. Excess weight increases the load on the foot, and it spreads out.
4. Change in biomechanics of movement, shift of load zones – women, in pursuit of beauty, more often choose irrational shoes, which include model shoes with a narrow nose and a heel height above 5 cm.In addition, in some types of business, women are forced to comply with corporate etiquette, where wearing tight, fashionable shoes is the norm. Such shoes overload the forefoot, muscles and ligaments become tired and overstretched.
Fig. The appearance of the “bone”
Thus, under the influence of risk factors, the arches of the foot flatten, flat feet appear, and if physiologically correct conditions for the foot cannot be created, such flattening will increase.
Therefore, in the presence of risk factors, in order to prevent the development of foot diseases, it is necessary to use preventive measures – wearing the right shoes, prophylactic orthopedic insoles and the use of means that improve the tone of the muscles of the foot and microcirculation: massage devices (rugs, exercise equipment, massage slippers).
If you do not engage in prevention and do not pay attention to risk factors, then the condition of the feet will worsen.
Fig.The appearance of the “bone”. Halux Valgus
At first, a person begins to notice that due to the expansion of the foot, one has to buy larger shoes, the feet get tired quickly, it is difficult to overcome the usual distances, edemas of the foot, calluses, and corns appear.
Due to overstretching and weakening of the ligaments, the first metatarsal bone begins to shift inward, and the thumb begins to deviate slightly outward.
Fig. Hallux Valgus
Big Toe Bone
This is the first manifestation of Hallux Valgus, which means hallux valgus.This deformity is accompanied by pain, inflammation, and the formation of a “bone” or “bump” at the base of the thumb.
At this stage it is possible to prevent the deterioration of the situation and slow down the development of the pathological process. You need to see an orthopedist. The doctor will give advice on the wearing of shoes and the use of orthopedic insoles for the correction of lateral flat feet and the initial manifestations of Hallux valgus. In addition, he will prescribe exercise therapy, self-massage of the feet.
If you do not start treatment on time, the pathological process will continue to develop, and the deformation will progress: displacement and inflammation will intensify, the “bone” will become larger and more painful and will no longer allow you to wear the usual shoes.The pain will not allow walking in heels all day and will have to be reduced in height. At this stage, you can still take action and avoid surgical treatment.
An orthopedist in such a situation will recommend wearing specialized orthopedic insoles, a bandage or corrector for the thumb, anti-inflammatory drugs in the form of ointments and gels, daily self-massage, physiotherapy, exercise therapy, therapeutic foot baths. It is important that the orthopedic insoles and abductor corrector should be used daily.
Unfortunately, specialists are faced with the fact that a large number of patients do not follow all the necessary recommendations and this leads to even greater deterioration. The gait changes, the shock load on the joints of the foot, lower extremities and spine increases, people experience severe pain both during exercise and at rest. All toes undergo deformations, which are called: claw-like, hammer-like, criss-crossing deformity of the toes.
It becomes almost impossible to pick up shoes in a regular store, you have to choose special spacious anatomical shoes.People restrict themselves to walking, it becomes difficult for them to stand. Many others join this disease – arthrosis of the knee and hip joints, osteochondrosis and protrusion of intervertebral discs, varicose veins of the lower extremities. At this stage, surgical treatment is indicated for most patients. Those who are contraindicated for surgical treatment due to concomitant diseases are prescribed anti-inflammatory drug therapy, physiotherapy and wearing frameless orthopedic insoles to increase comfort.
Can the operation be avoided?
You can avoid surgical treatment with a thoughtful, careful attitude to the most important organs of our body – the feet. This requires a balanced diet, an active lifestyle and adequate physical activity, massage, exercise therapy, wearing rational shoes, timely support during pregnancy, competent prevention of flat feet and wearing orthopedic insoles.
Methods of prevention and treatment
Physiotherapy exercises
Physiotherapy exercises (exercise therapy) is a very important way to avoid many problems with the foot, including Hallux Valgus.The only and important condition for achieving a lasting effect is constant exercise. Muscles quickly “forget” their function and, in the absence of training, lose strength and elasticity. Consequently, all the efforts that were made in the previous periods become in vain.
In no case can you choose a set of exercises on your own, without an exercise therapy instructor you can only worsen your condition.
Self-massage
Self-massage of feet is one of the techniques of mechanical action on tissues in the form of kneading, stroking, pressure, vibration, carried out both with our own hands and with special massagers.
For a lasting effect, regularity and a sufficient number of procedures are required.
Physiotherapy
Physiotherapy has long been an integral part of the rehabilitation and treatment of many diseases. Let’s list those that can help with a “bump” on the thumb: UHT – shock wave therapy, laser therapy, ultrasound, mud therapy. They will help eliminate pain, relieve inflammation in muscles and joints, restore mobility and prevent the transition of the disease from an acute stage to a chronic one.
All methods of physiotherapy must be prescribed by a physician – physiotherapist. Each method has its own indications and contraindications. Each method must be assigned courses.
Orthopedic insoles from Hallux Valgus
Exercise therapy, massage and physiotherapy cannot radically change the position of the muscles and metatarsal bones. For maximum effect, all these methods must be used in combination with specialized orthopedic insoles, designed specifically for the complex treatment of Hallux Valgus disease.
The use of orthopedic insoles is included in the clinical guidelines of the Ministry of Health of the Russian Federation as a method of conservative (non-surgical) treatment for hallux valgus. On the basis of clinical experience and recommendations of leading specialists in orthopedics, OrthoNic has developed full-profile orthopedic insoles “Butterfly” (art. 95).
These insoles contain:
- special frame profile Butterfly: multilayer frame made of thermoplastic material to create support under the metatarsal heads 1 and 5 and relieve the area under the metatarsal heads 2,3,4, due to the additional thickness of the frame.
- in the center of the insole, a drop-shaped soft roller (Seitz roller) to support and restore the shock absorption of the transverse arch, reduce pain in the midfoot and increase muscle tone.
- heel cup – stabilizes the back of the foot and keeps it in a physiological position.
- microline coating materials and latex for softness and comfortable microclimate.
How the Butterfly specialized orthopedic insoles work art.95
A special “Butterfly” frame with an extension for 1 and 5 fingers returns support for the heads of the 1st and 5th metatarsal bones, the pressure on the area of the heads of the 2nd to 4th metatarsal bones decreases. The roller effectively supports the transverse arch, the recess in the heel ensures correct positioning of the foot.
Thus, the design of the orthopedic insoles takes into account the specificity of the problem of patients with transverse flat feet and Hallux valgus. They correctly distribute the load on the foot, normalize the biomechanics of walking, cushion, reduce shock loads, protecting the feet, joints and spine.They reduce soreness and stop the progression of deformities of fingers, corns and calluses.
Orthopedic insoles “Butterfly” will allow:
- reduce pain in the foot
- reduce the formation of edema,
- prevent corns,
- improve blood circulation,
- restore damping function,
- keep the foot in the correct (physiological) position,
- redistribute pressure to the metatarsal bones,
- to prevent stretching of the ligamentous apparatus of the foot, which is the main cause of the pathological process.
Orthopedic insoles “Butterfly” are a simple and affordable method for the prevention and treatment of Hallux Valgus disease. You just need to choose the size of the insole and put it in the shoes that you are wearing this season.
Where to buy Butterfly insoles
Ask “Butterfly” insoles in orthopedic salons and shops in your city. You can find out their addresses here .
You can also buy insoles in the manufacturer’s online store.To do this, follow the link, put the product in the basket and place your order. Payment and the choice of a convenient delivery method is carried out right there on the company’s website. Goods are delivered throughout Russia.
It is easier to prevent than to cure!
Orthopedic insoles “Butterfly” are an economical way to prevent and treat diseases. They will save not only money, but also time. The insoles need to be purchased once and can be used for a long period of time, while reducing the number of visits to the exercise therapy instructor, massage therapist and physiotherapist.
Hallux Valgus is easier to prevent than cure.
Health to you and your legs!
Innovation in orthopedics: vibration insoles
What is this?
This is the world’s first four-dimensional vibrating insoles to improve blood circulation in the feet. In addition, they help the spine to take the correct position, which ensures an even posture and gait, and also stabilizes the health of the body as a whole!
Why do you need this?
For perfect arch support to help align the spine and maintain correct posture
As a person gets older, the balance of the body changes, becomes unbalanced, and this is harmful to health.In particular, due to improper posture and deformation of the foot from gravity, its arch gradually disintegrates and is in imbalance, with displacements that directly affect the entire body.
Posture becomes uneven and pains appear in the legs (twisting), knees (rolling), hips (falling), back (when bending), and also in the shoulders (when bending). This leads to rapid fatigue, and also causes other processes associated with pain.
For constant stimulation of your legs, which guarantees correct and stable blood circulation in them
We can say that the legs are the second heart. Why is that? It’s simple. Blood travels from the heart through the arteries and back through the veins. To overcome gravity and prevent backflow, veins work like valves. Blood must return quickly from the lower extremities, even if it is far from the heart. But most people cannot boast of good blood circulation. In particular, if the limbs are unhealthy, then the rate of blood circulation in them is significantly reduced, which leads to their numbness. It is important for a healthy body that blood is pumped quickly into the heart.Thus, stimulation of the foot is an absolute prerequisite for normal circulation.
We have a solution! You just have to walk with the innovative Vibro Orthotics insoles!
Features
Providing ideal support for the arches
Align your legs, the whole body will align!
Vibro-orthopedic device “Vibro Orthotics”:

Frequently Asked Questions and Answers
- Does the vibration keep working all the time?
Vibration is created only by the movement of the foot and lasts approximately 3-4 seconds.Vibrations occur even with the slightest movement. This results in magnetic resonance that is not subjectively felt. However, the sensations that a person will feel are caused precisely by the contact of the leg and the ground, for example, when jogging or walking. This is the only way you can stimulate your legs with constant vibration.
- How is vibration created without electricity?
This is a patented technology, vibration is created by the constant use of insoles.The product is environmentally friendly, and the device itself works in accordance with the vertical interaction of several magnets.
- I don’t feel any stimulation in my legs.
If you do not feel vibration when walking for a walk, this is because the circulation of the legs is insufficient and the sensitivity of the foot is also very weak. If you continue to wear the insoles, your blood circulation will improve, so the sensitivity of the foot will be restored and you will feel vibration.
- My feet are uncomfortable.
This is normal. It takes time to fix your legs, so it is entirely possible that you may feel discomfort for several days. You need to get used to the device to help and restore health to your lower limbs. Please refer to our 4 weeks program. Once you gradually get used to it, your legs will be much healthier.
About the patent
Our patents are registered in the USA, China, Japan, South Korea.Other patents are pending. In the Russian Federation, the device does not require certification, as evidenced by the official response of the Certification Body to our Company.
Clinical test
We conducted a clinical study (40 people, 12 weeks).
Clinical trial (pulse power, increased pulse energy, impaired peripheral circulation, blood vessel pressure index, BMR, PMR, adipose tissue mass, BMI, fat) for a vibrating feeder with an integrated iMOOV chip has shown that it effectively reduces body fat in body and balances by stimulating metabolism.
At the same time, the pulse test showed an increase in the power of the pulse and its energy, as well as an improvement in blood circulation and blood pressure. Thus, by vibrating, the magnetic field helps to improve the movement of blood through the vessels and veins, increasing the pulse and lowering the pressure.
Test report
Vibration energy helps to further increase the speed of absorption of a shock by 8% due to its dispersion. This vibration frequency (10 ~ 15 Hz) is optimal, and therefore affects the enhancement of immunity (“SMR” frequency range).
Foot Reflexology
Magnetic vibration stimulates unique acupuncture points in the arch of the foot, affecting the solar plexus, kidneys and heart.
About
MS Networks Korea was founded in 2006 in South Korea. The creation of insoles is based on the manufacture of orthopedic shoes. Initially, the production was developed for global brand companies, with an emphasis on sports models. They were luxury sneakers – functional and orthopedic.However, the cost per pair was quite high. The developers have worked for a long time to make the product more accessible for general consumption, while maintaining all the functionality and uniqueness of the products, while making it possible to use the shoes on a daily basis. Soon, the world’s first vibrating insoles were released to perfectly support the arch of the foot and to improve blood circulation in the lower extremities. The uniqueness of the insoles lies in many aspects, including this makes it possible to wear them daily with different shoes.The insoles are widely used in everyday life of people and are successfully sold both in the Korean market and abroad.

Orthotics in the conservative treatment of flat feet
The problem of conservative treatment of combined flat feet remains extremely urgent. An imbalance between the loads of the tested foot and its capabilities leads to an overload of its anatomical structures with the appearance of deformities and deterioration of function, which has a negative effect on other parts of the musculoskeletal system and leads to the development of degenerative diseases in the joints of the lower extremities and the spine. The transverse flatness of the foot is characterized by imbalance and weakening of the musculo-ligamentous apparatus of the forefoot, which leads to a fan-shaped divergence of the metatarsal bones and to a change in the loadability of the metatarsal heads. On the I and V metatarsal bones, the load decreases, while on the middle ones it increases. The mobility of the extreme metatarsal bones (I and V) occurs not only in the horizontal plane, but also in the vertical one (they seem to rise upward), while the middle metatarsal bones are pressed against the sole, creating conditions for the deviation of the first toe outward, which, when enlarged, in in turn, contributes to the deflection of the first metatarsal bone inside.
Insufficient preventive measures, and often simply ignorance of the population about their capabilities, lead to the fact that some patients turn to doctors for help with advanced deformities requiring surgical treatment. Therefore, the number of surgical interventions carried out in this regard is steadily growing. At the same time, despite the serious success of surgical correction of deformed feet, most of the patients very carefully resort to this type of treatment, preferring the conservative one.
The complex of conservative therapy is based on a combination of forced, gradual and constant correction of deformity elements using exercise therapy, manual therapy, massage and some other physical treatments.
One of the main corrective devices is orthopedic insoles with the layout of the transverse and longitudinal arches of the foot. Their principal capabilities and significance for the majority of orthopedists are known. Therefore, detailed variations in different conditions and the elasticity of the feet, the degree of spreading, the age of the patients on the one hand, and the features of the designs and materials of the insoles themselves, on the other, require a separate detailed consideration.
We would like to dwell on one of the leading components in the system of complex rehabilitation of functional disorders of the foot – individual orthotics. For the latter, the computer system CAD-CAM of the firm “IMAGO” Italy was used, consisting of a strain gauge platform, a scanner and a milling machine with programmed control. All devices are controlled by one computer.
Foot orthotics using the CAD-CAM system consists of the following technological links:
Examination of feet on a strain gauge platform in static, postural and dynamic modes with analysis of the results obtained;
Stop scanning in static mode;
The obtained data are entered in a graphical mode into a three-dimensional modeling program and virtual modeling of insole orthoses is performed;
Upon completion of the modeling, the selection of material from special semi-finished products is carried out, including both single-component and multilayer blanks with different density parameters;
After placing the workpiece in the milling machine, the milling program starts;
Final finishing and checking the correctness of the shape of the insoles along the patient’s leg using a barometric platform and, if necessary, correcting the product.
Among the complex problems of modern orthopedics, an important and urgent place is occupied by the treatment of patients suffering from static deformities of the feet. Moreover, one of the most common diseases is the transverse flattening of the foot with hallux valgus.
Considering these circumstances, in this publication, we want to draw the attention of specialists to some additional orthopedic correctors produced by MNPO “PARIZO” (Russia), detailed descriptions of which have not yet been found in specialized domestic literature, since until recently their industrial production did not exist.
1. Orthopedic cuff for the foot is a brace for the forefoot, which is produced in two variations – detachable and one-piece (Fig.).
The detachable cuff (patent 2114582) consists of an elastic tape, at the ends of which on the inner and outer sides, respectively, “Velcro” are sewn, adjacent to each other when applied. At one end under the “Velcro” there is a pocket with a hood-valve. The pocket fits an insert made of a one-sided convex piece of semi-rigid plastic or latex.The perimeter of the base of the insert is egg-shaped.
The cuff is used as follows. To remove the heads 2, 3 and 4 of the metatarsal bones from under the load, the tape of the open cuff is placed under the forefoot so that the pocket is the convex side under these heads. Then the tape is pulled and its ends are aligned in such a way that the surfaces of the “Velcro” coincide and stick together. At the same time, the forefoot section is dosed together until the normal size of the diameter is restored, and the transverse arch is formed by the local pressure of the liner.
The one-piece cuff also consists of an elastic tape, but the ends of which are sewn together and the sole has an insert of the same shape and size, reinforced with a piece of leather or leatherette. Considering that the one-piece cuff is not intended to be adjusted during operation, then when choosing and fitting it is necessary to strictly observe the size of the forefoot.
2. Interdigital corrector-separator (orthopedic “coil”) patent 2120260, consists of a base in the form of an elongated wedge-shaped oval shape along the edges with transverse channels and lateral oval “cheeks”
The separator is made of elastic plastic of the required softness and equipped with a rigid tubular sliding key.Its channels are blind from below and in cross-section are represented by truncated circles. The corrector is used as follows. Every day, between the first and second toes of the foot, the base of the separator is pushed in with its narrow edge until it stops in the proximal interdigital space so that the solid “cheek” is located below, and the “cheek” with channel openings is on top of the foot.
A key is inserted into one of the channels, depending on the required amount of distraction, to fix this value.In the course of treatment, as necessary to increase the degree of correction, the key is moved to a more proximal canal.
When the first toe deviates up to 20-25 ° and in the absence or insignificant phenomena of deforming arthrosis of the first metatarsophalangeal joint, the separator is made of “gel”, more elastic rubber and without channels, the method of using the “gel” corrector is similar.
3. Orthopedic back-splint for the correction of the first toe (patent 2I4520I5) consists of a frame, a half-cuff and a fixing belt.
The frame is made in the form of a bent wrap with two symmetrically diverging slats having longitudinal slots at the ends and teeth on their upper sides. The slots have cutouts. The half-muff is made in the form of a soft strip with slits for slats. The fixing band is made in the form of a Velcro tape, one end of which is fixed in the slot, and the other is passed through the other slot of the rails.
Apply a bandage tire as follows. The first toe of the foot is rejected, taking it out of the vicious position (or improving the position) and the frame is placed on it so that its coverage enters between the first and second toes, and the slats are, respectively, above and below the foot.
The half-patch is moved along the slats so that it is slightly higher than the first metatarsophalangeal joint.
Finally, the foot is covered with a fixing band and, by pulling it, the first toe is deflected at the required angle with respect to the second. Thus, after a series of procedures, it is possible to improve or restore (depending on the initial picture) the natural position of the first toe, or to prevent the progression of deformity.
4.Corrector – straightener of hammer-shaped second and third toes (patent 217 3118) consists of a flat-oval-shaped foot insole glued from two layers of elastic material. The lower layer protrudes 4-5 mm from under the upper one along the entire perimeter.
In the front narrower part of the insole, a semi-rigid plate is glued between the layers, through which the layers are cut through several through longitudinal-parallel slots corresponding to the location of the toes. Through these slots a rubber band is threaded, one end of which is attached to the insole by a seam; the shape of the insole changes depending on the number and location of the toes to be corrected. The corrector is applied as follows. The tape is pulled through the slots so that loops are formed on both sides of the insole.
Place the insole under the forefoot so that the semi-rigid part of the insole is under the toes, and the toes to be corrected enter the loops. The back of the insole is located under the transverse arch of the foot.
Then, alternately pulling up the tape, they achieve that the fingers, pushed into the loops, are pulled to the insole, take and retain their natural shape.Moreover, the tension of the tape in magnitude is taken such that the correction of the fingers takes place, but at the same time their soreness is excluded. During the course of treatment, the tension of the belt may change depending on the results. After installing the corrector, a sock and ordinary shoes are put on the leg, allowing the patient to move freely.
5. Metatarsal rollers (Seitz’s roller). They are used in the presence of corns and pain in the forefoot, as a result, the heads of the middle metatarsal bones are raised above the level of the first and fifth heads, increasing the load on them. The isolated use of metatarsal rollers is recommended for women wearing narrow, high-heeled fashion shoes. Their varieties are shown in Fig.
In conclusion, I would like to note that the differentiated use of modern corrective devices (we have presented only a few) in conservative complex treatment makes it possible to reduce and in some cases eliminate the main elements of deformity and provide a sufficiently positive effect.
We analyzed 230 patients with varying degrees of severity of longitudinal-transverse flat feet. The analysis of the results of the computer examination of the feet allowed the most complete assessment of the functional and static properties of the feet, and the identification of overload zones and defects. Computer modeling of the insoles made it possible to produce individual-shaped products, and a wide selection of materials of various densities makes it possible to choose the best option for each clinical case and to differentially relieve individual zones of the foot.
Computer diagnostics data and virtual models of insole orthoses for each patient are stored in the computer database, which allows dynamic control over the condition of the feet during repeated calls and make the necessary correction in the manufacture of subsequent insole orthoses. The analysis of the strain-gauge study of standard orthoses under static and dynamic load of the patient makes it possible to assert the possibility of using this method for the correct selection of ready-made insole orthoses, and the potential possibilities of three-dimensional modeling of orthoses give the orthopedist a new reliable tool for the creative implementation of scientific and practical ideas.
Individual orthopedic insoles to order for children in Moscow: reasonable prices
It is important to monitor the development of the baby’s foot. At the slightest deformity, we recommend contacting an orthopedist ON CLINIC. He will make customized orthopedic insoles for any shoe. This is enough to correct the deformity of the foot.
Shoes for children of the 1st year of life. Why is it important?
Many mothers believe that a baby who has begun to walk should do it barefoot or in socks.It’s a delusion!
In children of the first year of life, the articular-ligamentous apparatus is poorly developed, the muscles of the lower extremities have not yet strengthened. During standing and walking, the ankle joint and foot are deformed. To maintain the vertical position of the body, the position of the knee and hip joints changes compensatory, and ultimately the curvature of the spine occurs.
The reason for the development of this pathological process is a hereditary factor, as well as increased elasticity of the connective tissue, which has been observed in recent years in many children.
The first steps need to be done with shoes on. In this case, the child’s weight rests on the back of the shoe, the instep supports the foot in a horizontal position. The special Thomas heel allows you to walk steadily. This is enough to prevent deformities of the lower extremities.
Insoles for children. When can you not do without them?
Individual orthopedic insoles are recommended for a child if he has:
- acquired or congenital deformity of the foot;
- various types of flat feet;
- scoliosis and poor posture due to asymmetric leg length.
Children’s orthopedic insoles allow you to align the arches of the foot, as well as normalize the position of the heel and toes. The load on the spine, knee and hip joints will be significantly reduced.
As a result, it has a beneficial effect on the development of joints and the spine. This is immediately noted by parents: in children, the gait becomes correct, posture normalizes.
In case of deformity of the feet, the specialists of On Clinic Baby, in addition to wearing orthopedic insoles, recommend courses of therapeutic gymnastics. They are developed individually for each child. Exercises are performed with parents, but with the obligatory periodic supervision of an orthopedic surgeon. The use of individual orthopedic insoles in combination with therapeutic exercises allows you to achieve the maximum effect in correcting children’s feet.
Advantages of making individual children’s insoles at On Clinic baby
IN ON CLINIC, individual insoles for children are made by doctors! They manage to fully take into account the anatomical features of the children’s foot.Not only the individual characteristics of the baby are taken into account, but also the shoes that he will wear.
When making insoles, the following are guaranteed:
- fast production, the order will be produced within 20-30 minutes;
- the use of non-toxic high quality material,

Individual selection and production of orthopedic insoles for athletes at the NL-Clinic
Rehabilitation physician Alexander Davydtsev tells why a runner needs orthopedic insoles, what tasks they cope with and how to choose them correctly, taking into account the individual characteristics of the athlete.
A sad feature of the life of a modern person: we began to move less, but at the same time walk more on the same type of surface, smooth and hard. And the flatter the surface, the more the individual segments of the foot are overloaded. On top of that, our shoes are more style than functionality. And even with flat insoles inside.
What does this lead to? First of all, to problems with feet. First, there is swelling, fatigue of the legs and numbness of the feet.And further along the chain – pain in the lower back or knee, headaches. Ultimately, the quality of life begins to suffer on many fronts, and the athletes’ performance also deteriorates.
Feet are the foundation on which our body balances. And this analogy for them was invented for a reason: try to find at least one house without a foundation. Here, that’s it!
Therefore, think about this foundation of the body and decide how to strengthen it. One easy solution is the right insoles.
Why do we need orthopedic insoles
1. Correctly distribute the load on the foot: include underused muscles, relieve excessive load from overloaded ones.
2. Improves mobility and cushioning, thereby solving the problem of “flat surfaces”.
3. Provide comfort for the legs, even under heavy loads. And as a nice bonus – the legs stop freezing.
4. Improve posture: shoulders straighten literally by themselves! Without the hated posture correctors and exercises, simply due to the fact that the body has a correct vertical axis.

5. They solve almost any problems with feet: from flat feet to spurs, from calluses to arthrosis or deformities of the fingers.
6. Increase the body’s endurance: thanks to neurobiomechanical stimulation of the foot, movement patterns are corrected through the spinal cord. As a result, the heart rate may decrease, and the running speed and reaction speed may increase.
7.They balance the autonomic nervous system: there are many receptors on the foot, and the stiffness of the insole will affect them.
8. Helps prevent injury for both professional athletes and amateur runners. This is a very important point, because trauma today is a loss of results in the future.
How to choose insoles
Stimulation of certain zones of the foot can remove muscle imbalance and thereby normalize movement patterns. All of these zones are different, and even for one person, the parameters of the right and left legs may differ significantly.Therefore, the choice of insoles is a purely individual question. No ready-made copies in orthopedic stores – only harm! NL-Clinic specialists work with the Formthotics medical system and are sure that there are simply no worthy analogues with such a large evidence base of effectiveness in the world.
Only doctors are allowed to manufacture Formthotics orthopedic insoles: podiatrists, orthopedists or sports doctors with knowledge of applied kinesiology. The podiatrist takes into account many factors: anatomy, physiology, biomechanics, the specifics of a particular sport.In addition to standard orthopedic, postural tests and visual diagnostics, the method of manual muscle testing, respiratory and neurological tests is used.
Getting the insoles right is only part of the challenge. To maximize the effect, NL-Clinic specialists use Applied Kinesiology.
Kinesiology is the science of movement in all its manifestations: muscle contraction, ligament tension, position of articular surfaces, movement of various fluids in the body, distribution of shock loads, movement of internal organs, cerebrospinal fluid and even a nerve impulse.Applied Kinesiology is a diagnostic system with its own applied tools.
At the NL-Clinic, podiatry (foot and lower leg treatment), kinesiology, manual therapy and sports medicine go hand in hand. The doctors of the center are sure that orthopedic insoles should be a medicine, and not act as a crutch.
Before the selection of the insoles, the patient undergoes a thorough diagnosis on the podoscope, the muscles of the foot are tested kinesiologically, and in case of dysfunctions, the appropriate correction is immediately carried out.Instability of attachment points, the consequences of blows and bruises, etc. are also monitored. In some cases, special therapeutic exercises are prescribed.
If there are no problems according to the tests, then the so-called provocation is carried out, that is, the conditions that the foot experiences during sports loads are artificially created. If the provocation is positive, this latent state is corrected. And only after all these tests are effective insoles selected and formed. Such efficiency cannot be achieved without the participation of applied kinesiology.
How is the process of making insoles
Modeling of insoles takes place in shoes with the participation of the athlete himself.
The workpieces are heated to a temperature that does not burn the foot, but is sufficient for the development of plasticity of the foam material. Formation takes place in the neutral position of the feet, when the axes are anatomically preserved. The insole acquires 100% foot relief.
After the insole has cooled, the support will be directed to the anatomically correct position.The roller that forms the transverse arch of the foot is glued based on the bony landmarks of the athlete’s foot. And if this is not enough to align all the axes of the body, special correctors additionally form the lifts of the necessary zones of the foot.
To achieve maximum effect, individual insoles are made in the athlete’s competition shoes. When replacing shoes, old insoles can always be adapted to new sneakers with special correctors. The everyday insoles can be put into any shoe of the same type – everything will work.
Cases
- Andrey Kozlov and his team, triathlon
The insoles are made for injury prevention. The team was pleasantly surprised: the heart rate at the same load became 5% lower than before using the insoles. This indicates a competent distribution of the load on the muscles of the legs, which in turn adds endurance to the athlete.
- Daria Likholetova, 17 years old, crossfit and athletics
The athlete complained of persistent pain in the knee joints.Without kinesio taping or knee pads, I could not run even a kilometer without pain. Agree that at this age it is frustrating.
Specialists of NL-Clinic performed diagnostics on a podoscope and diagnosed transverse and longitudinal flat feet. A test of the muscles supporting the arches of the foot showed weakness. And the reason was … the wrong bite!
Kinesiology is engaged in uncoiling such tangles of bonds. To compensate for the malocclusion, the body sacrificed its feet along the deep muscle chain, because it was more important for it to receive chewed food.
The muscle test spoke for itself. It took time to correct the bite, but the girl wanted to train now without pain in the knee joints. Doctors made insoles that began to support the arches of the foot, reflexively turn on the muscles and relieve some of the shock load. Result: marathon in 2 weeks without pain and knee pads!
- Oleg Dyadkov, 35 years old, weightlifting
The athlete complained of lower back pain when squatting. The clinic tested 12 pairs of insoles of different stiffness.The pain disappeared only with the use of one of the pairs. Doctors modeled this pair under the foot, after which the insoles worked in full force. Soon, the athlete began his usual training.
How to care for the insoles
The insoles are easy to clean, the main thing is not to exceed the water temperature of 40 degrees and do not dry near heating elements.
Depending on the load and weight of the athlete, insoles last up to 3-4, and sometimes up to 6 years.
Special offer
For the readers of our magazine, the NL-Clinic medical center has prepared a special offer: a 30% discount on the appointment of a specialist and the selection of insoles. To get a discount, tell the administrator the code word “marathon runner”. The promotion will last until the end of August 2019

Orthopedic insoles are removable products that perform various functions and ensure comfortable wearing of shoes and the absence or reduction of pain in the feet and joints during diseases or heavy stress. They are prescribed for arthrosis, arthritis, hallux valgus, heel spur, flat feet and other diseases.
Orthopedic insoles: effects and use cases
Orthopedic insoles – prosthetic and orthopedic products that are able to maintain and correct the position of the legs. Unlike conventional insoles, the orthopedic option creates a healing effect, reduces fatigue and pain in the legs.
Useful properties
- Support for arches of feet in the presence of flat feet, prevention of various injuries.
- Relief of painful areas of the feet (bones, heel spurs and deformed toes).
- Correct distribution of the load on the feet.
- Ensuring correct heel fit.
- Cushioning while walking. The joints and spine are protected.
- Reduction of painful sensations.
- Normalization of blood circulation and protection of muscles from excessive stress.
- Reduces the likelihood of calluses or calluses.
The orthopedic insoles are designed with various functions as described in the figure below.
When are insoles used?
Insoles are used for various purposes:
- The hygienic variety helps to avoid the appearance of fungi and unpleasant odors, has a warming and massage function.
- Prophylactic view includes a variety of standard orthopedic (made from average pads) and individual anatomical (created from individual human footprints) products.The second option reproduces the arch with great accuracy, provides support and muscle relief.
- The Healing Variety is a customized product based on average stocks. They are characterized by the presence of additional elements that patients need.
Varieties of orthopedic insoles
Certain criteria exist to help you classify goods.
Form
By form are:
- Full-size.
- Half insole – a product designed for shoes with heels, for various model options in which full insoles cannot fit.
- Insert – interacts only with problem areas.
- Heel pad – special heel pad, recommended for heel spurs.
Size
When choosing products, it is important to pay attention to the size in order to choose the most successful option that will provide the maximum effect.
- Products can represent each size (38, 39, 40, and so on) or have a “double” size that combines two sizes (40-41, 42-43, and so on). In order to make the right choice, it is necessary to make accurate calculations and measure the length of the leg.
- There is no one size fits all, as each corrective element of the product has its own specific location in which it stimulates or relieves muscles and joints. As for conventional earbuds, they differ in general application (protect feet from cold or rainy weather), which explains the presence of a single size.
- Products with a “double” size can be cut. You can see special marks on the goods with which you can carefully separate the excess length.
In order to carefully select the correcting device, it is necessary to take a measurement. Product lengths may vary slightly from manufacturer to manufacturer. To clearly determine your size, you need to circle your leg on paper. In this case, the handle must be kept in an upright position. Then we draw a line from the middle of the heel to the middle of the big toe, measure the length and get the desired result in centimeters.
Material
The orthopedic version is made of leather, cork, thermoplastic, carbon fiber, ethylene vinyl acetate, latex, cloth, fur, fleece or bike.
The use of such high-tech materials as EVA, Microliner and various polymers is gaining more and more popularity, from which durable products are obtained that can absorb excess moisture and remove unpleasant odors. The material has good shock-absorbing properties, hypoallergenic.
Functional principle
- The vaulted version supports and relieves the vaults and also helps to improve the damping process. As a result, a decrease in soreness and an increase in leg endurance can be observed.
- The arch-forming look supports the foot, creates additional stimulation, which makes it easier to form the inner arches.
- Corrective option allows you to correct the position of the legs (biomechanical alignment process). Such a product corrects the structure of the lower extremities, which improves the function of the legs, reduces pain, reduces fatigue and prevents deformation of the shoe.
- The unloading variety redistributes pressure from problem areas to other parts of the leg. As a result, there is a decrease in pain, no threat of ulcers. The functions of the leg are improved.
Types of footwear
- Sports products are particularly comfortable and comfortable, provide minimal gaps between the feet and sneakers, cycling shoes or ski boots, hold the heels and arch, and help prevent injuries, calluses.The sport option reduces fatigue and increases endurance in training, competition or hiking.
- Half insoles are most often worn with summer shoes, ideal for sandals or open shoes. This variety will help to properly distribute the pressure on the legs and reduce fatigue.
- A full-length orthopedic option is popular during winter to help support the feet during a variety of activities. A well-chosen product performs the function of shock absorption, protects the feet, joints and spine.
- Thin and invisible orthopedic options are perfect for open shoes, providing comfort, elasticity and softening the load on the lower limbs. Can be worn with heels.
- Orthopedic insoles for closed shoes have a strong frame, heel cushion and soft foam roller. The products help to effectively support the arches of the legs, and also reduce the shock load on the heels, joints and spine.
Purpose of products
- Therapeutic models are designed to support and correct the position of the feet and help in the fight against various diseases, including the treatment of flat feet, heel spurs, hallux valgus, joints and spine.
- The prophylactic type helps to avoid the development of pathologies, reduce the load on the lower limbs and maintain the optimal position of the feet.
- Comfortable models lie tightly in the shoe and prevent shifting or creasing during vigorous activity.
Features of the insoles
- Massage products improve blood circulation and reduce fatigue.
- Products with an instep support are distinguished by a strict correspondence between the sizes of feet and products.Each section of the leg is strictly closed. There is both a longitudinal version and a combined one (helping to treat flat feet and carry out prevention).
- Children’s – a specialized version designed for children. Supports the transverse arch and prevents the deformation of the fingers due to the design features.
- Maternity pads are worn at all times. They prevent deviations in the musculoskeletal system of the leg, prevent various threats of violations. A correctly anatomically constructed design relieves the parts of the feet that are subject to the main pressure.
- Corrective products promote shock absorption when walking in various parts of the lower limbs.
- The diabetic option prevents the deformity of the lower extremities, which is prone to people with diabetes. Diabetic products allow you to maintain the correct blood circulation and relieve painful sensations in the legs.
Selection of insoles for various diseases
With a heel spur
Heel spur is a common painful condition.In the fight against the problem, the heel pad, which has a special design, contributes to comfortable and comfortable wearing of shoes and a therapeutic effect, helps. Heel pads are made using high elasticity materials.
Heel pads are prescribed to the patient to speed up healing and remove excess pressure on soft tissue, eliminate pain in case of illness, normalize blood circulation and metabolism, which is disturbed with a heel spur.
With flat feet
With mixed flat feet, orthopedic products are able to support the legs in the correct anatomical positions.It strictly performs a shock-absorbing function, prevents the progression of the disease, as well as reduces pressure on the spine.
To combat longitudinal flat feet, products with high instep supports are used, which support the longitudinal arches, thereby restoring the normal biomechanics of the legs. Products with an instep support relieve excessive stress, improve blood circulation, increase endurance, and also relieve pain and prevent the appearance of a heel spur.
For patients with transverse pathology, it is recommended to use insoles with a pad, which evenly distributes pressure on the front sections of the legs, and a frame that protects and supports longitudinal waters, as well as redistributes loads along the feet. A heel shock absorber is possible.
With hallux valgus
To combat hallux valgus, a therapeutic option can be used, which serves to correct the deformed arch of the foot. The products are rigid in shape. It is possible to use prophylactic or therapeutic and prophylactic types, the insoles of which can be shortened.
With arthrosis
Insoles for arthrosis help to create increased comfort due to the presence of interstitial layers, which are made of special shock-absorbing materials. These are individual products that allow you to evenly distribute the load on the foot and reduce painful sensations.
For arthritis
The insoles for patients with arthritis are distinguished by the presence of a special metatarsal cushion, a rigid frame and a cup-shaped heel.These elements support the foot and heel, relieve pain and serve well in providing a light massage effect and blood flow to the feet.
Parameters for correct selection
There are certain criteria by which the required model is selected, namely:
Assignment | A consultation with a specialist will help identify pathologies at an early stage of development and choose the right option to deal with deviations. Models can help in the treatment of various diseases or serve for preventive purposes. |
Support | To make a choice in favor of the right model, you need to determine what effect your legs need. For example, products can relieve pressure on the spine and joints, maintain general muscle tone, improve blood supply, make vigorous activity more comfortable and relieve pain in the lower extremities |
Material | There is a huge variety of materials used: cork, leather, carbon fiber, thermoplastic, EVA, latex, fur, bikes and others.Good products are durable, they can absorb excess moisture. |
Height | Orthopedic products have different heights. With the right choice, the model will allow you to walk comfortably: the ankles will be free, and the mid-feet will fit more tightly to the shoe. |
Hardness | The frame version, in contrast to the frameless one, is distinguished by its rigidity and is suitable for those who are engaged in vigorous activity. Frameless soft models help relieve leg muscles. |
Size | “Double” size combines two sizes (37-38, 39-40), other products represent only one size (41, 42 …). Custom products are perfectly matched to the patient’s size. |
How to wear orthopedic insoles correctly?
To get the most out of your insoles, there are some tips to follow.
- In winter, it is better to use thick products that are embedded in boots, low shoes or boots. The special version of the insoles can be coated with a natural wool layer to provide a warming and shock-absorbing function. Correct placement can strengthen muscles and ligaments.
- In the summer, products are invested in ballet flats, shoes, sneakers, sandals, sneakers and so on. Each piece should clearly conform to the curves of the leg and repeat the arches of the feet.In order to use the product in summer with benefit, it is necessary to insert it into the toes of the shoes. Heels and heels should be in close contact.
- The period of use of the liner varies according to the feet and age. Adult users are highly prone to pathologies, therefore, orthopedic products can be worn continuously.
Potential harm from using insoles
Wearing orthopedic products can be harmful when:
- The patient selected the wrong product, did not take individual measurements.
- Incorrect size selection.
- Wearing shoes that do not fit the selected items are in progress.
- A low-quality product was purchased that only brings harm.
- The doctor has misidentified the problem or disease.
Advantages of custom made insoles
- Custom-made to create quality products that support the longitudinal arch, heel cushions and other important elements.These products adhere to all modern standards to help you get the most out of wearing.
- Customized products take into account the height of the arches, the length of the fingers and other properties of the lower limbs, which allows for the correct positioning of each element and the correct size. Factory production does not have the ability to take into account small details.
- Correctly designed custom-made insoles prevent the development of pathologies and various diseases.
Features of children’s individual insoles
Children’s insoles eliminate pathologies, form a healthy position of the arch of the feet, and also provide the necessary conditions for the correct distribution of the load on the joints and muscles.The advantages of creating customized products for children are:
- Ability to create full-ice, full contact insoles.
- Materials of different densities have a beneficial effect on children’s own muscles.
- The doctor prescribes the duration of wearing and carefully monitors the process.
- The product contributes to the correct development of the feet, puts the heels in the correct positions, forms the arches of the lower extremities and relieves pressure on the spine, hip, knee and ankle joints.
Service life and maintenance rules
Service life can usually be found on packages or instructions. The average term is 6 months. For proper care:
- Dry items daily, avoid exposure to the sun or interaction with heating devices. It must dry naturally.
- Do not machine wash or use running water.
- Avoid exposure to high temperatures.
- Wipe clean with soft cloths soaked in alcohol or soap solutions.
Cost of insoles
The price of making orthopedic insoles varies depending on the material used, the desired size, various nuances of the feet, the height of the backs or the characteristics of the heel cushions, the type of production (mass or individual), the volume of costs and the country of manufacture.
Thus, it is very difficult to make the right choice, which depends on a huge number of important criteria that must be taken into account. To give preference to the right products, you need to consult with your doctor or carefully study the proposed material and make your own choice.
Articles »Functions and features of orthopedic insoles
Orthopedic removable insoles provide a comfortable feeling when worn, reduce pain in joints, feet, and perform many other useful functions.
Purpose of insoles
Products relieve stress during injuries and stress, can be used to correct, improve sports results.The insoles are especially useful when walking, running long distances, work, during which you have to stand on your feet for a long time.
The main loads in an upright position in humans are experienced by the foot. However, they are distributed unevenly. This can lead to rapid leg fatigue and discomfort. Large loads of individual muscles can lead to the formation of flat feet, various deformities of the foot.
It is the orthopedic insoles that allow you to position your feet in an ideal position and reduce the risk of developing pathologies. With the help of orthoses, the load on the legs is distributed correctly.
Useful product functions
The main task of the insoles is to correct the incorrect position of the foot. What else are orthopedic aids used for:
· reduction of pain (arthralgia) in the joints;
· support of the arch of the foot;
· restriction of thumb mobility;
· prevention of deformity of the spine, musculoskeletal system;
· reduction of foot trauma when walking due to heel spur;
· giving a person stability when walking, being in an upright position;
· reduction of fatigue;
· prevention of flat feet development;
posture correction;
· normalization of blood supply;
· reduction of shock load on the spine, knee joints, ankle, pelvis due to foot amortization;
· improvement of blood circulation.
The list of tasks that the insoles can solve depends on the configuration of the model.
Design features of shoe inserts
Orthopedic appliances differ in configuration. It can be soft (frameless) and rigid (frame). The former are used to relieve the foot, reduce discomfort, protect the ligaments, and distribute the load more evenly. The peculiarity of the insoles is the lack of shock absorption.
Frameless models are used when there are no significant pathologies.
Rigid insoles effectively support the arch. Adaptations are recommended for developing flat feet, a lifestyle that requires long standing. They are suitable for athletes, active users. Features of insoles – the need to adapt to a rigid structure.
Insole length
Manufacturers’ orthoses are available in full size and occupying only ¾ of the foot. The latter are called half insoles. The products are used to shape the correct instep and also to prevent the leg from leaning towards the inner edge of the foot.¾ models are comfortable to wear with heels that don’t fit in full sizes.
There are also small pads for individual zones and heel pads on sale. The latter are used for heel spurs, cracks, corns.
For open women’s shoes with a high heel, manufacturers produce models with a heel.
Orthotic form
There are three types of insoles:
- longitudinal – for patients with flat feet, for correcting certain pathologies by maintaining the arch;
- transverse – have one or two wedges (on the heel, near the toe), are used to neutralize the longitudinal arch;
- combined – for flattening the longitudinal and transverse arch, more comfortable when worn in closed shoes.
Only correctly fitted orthoses can effectively restore the shape of the foot.
Insole materials
Popular materials for the outer covering of orthoses:
- genuine leather – breathes, absorbs moisture, absorbs odors;
- silicone – durable, resilient and durable;
- perforated velor – skin-friendly;
- microfiber – absorbs moisture and fragrances, breathes;
- leatherette (polyurethane) – not afraid of water, durable, does not get wet, does not have air permeability, can accumulate odors;
- fabric – comfortable and soft to use, not highly resistant to wear, breathable, non-moisture resistant.
