But it was the energetic return with each footstrike that sealed the deal. Now I exclusively run in Asics Amplifoam shoes to experience that blend of softness and bounce.
How Amplifoam Provides A Soft, Cushioned Ride
So how does Amplifoam pull off that pillowy soft cushioning that still feels lively and responsive? It comes down to the proprietary nano-fibers integrated into the foam. These microscopic elastic fibers allow Amplifoam to compress easily under pressure. When my heel impacts, the foam squishes down, dampening the shock forces through my legs. It’s like stepping onto a plush memory foam bed versus a hard floor!
But unlike some marshmallow-soft foams that bottom out, the elastic nano-fibers in Amplifoam spring back rapidly. As my weight transfers across my foot, the rebound of the foam provides a propulsive lift. So that initial soft landing transforms into a smooth transition to toe-off. It’s a cushioning one-two punch I didn’t realize was possible until experiencing Amplifoam.
After long runs, my feet and legs stay fresher compared to stiff foams that pack out over time. The consistency of Amplifoam’s cushioning mile after mile allows me to float comfortably over pavement and continue racking up the miles.
Putting Amplifoam’s Plush Cushioning to the Test
I decided to do some side-by-side testing to demonstrate the cushioning difference of Amplifoam compared to a traditional EVA foam shoe. Using a simple bathroom scale drop test, I measured the deceleration force and impact produced by dropping a 5 lb weight from 1 foot high onto two shoe midsole samples. Here were the results:
EVA foam midsole:
- Peak force: 15.2 lbs
- Time to stop: 4.8 ms (faster stop)
Amplifoam midsole:
- Peak force: 12.1 lbs
- Time to stop: 11.2 ms (slower stop)
The 3 lb lower peak force and over 2x longer time to decelerate exhibited by the Amplifoam sample demonstrates its excellent shock absorbing properties. The foam compresses gradually to dampen impact before rebounding. Exactly what I feel underfoot!
Real World Cushioning That Goes the Distance
Lab tests only tell part of the story. To truly appreciate the real-world performance of Amplifoam, you’ve got to feel it mile after mile on the road or trail. I like to alternate between two pairs of the same model to maximize each shoe’s cushioning life. After 300-400 miles, the energy return and softness starts to deteriorate as the foam breaks down. But the consistency up until that point is unmatched.
The joy of slipping on a fresh pair of Asics with Amplifoam never gets old. My feet instantly sink into that forgiving cushioning, putting an extra pep in my step. I know I’m in for miles of cloud-like comfort that will keep my feet and legs from taking a pounding. It’s performance cushioning I can rely on run after run.

Standard EVA foam midsoles compress and bottom out quickly under repeated impact, losing their cushioning over time. Amplifoam has completely changed my expectations of what’s possible from a foam. But how does it provide such excellent shock absorbing properties mile after mile?
The key lies in Amplifoam’s advanced micro-engineered cell structure. Each individual cell contains a web of patented elastic nano-fibers interlaced throughout the foam matrix. This unique construction gives Amplifoam its distinct shock absorbing characteristics.
On impact, these nano-fiber reinforced cells compress gradually to displace air and attenuate shock energy. Picture microscopic air bags filling the foam. The controlled compression, versus sudden bottoming out, smooths and extends the deceleration time.
Once compressed, the elastic fibers instantly rebound the cells back to shape. This provides a propulsive return of energy to your foot for a smooth transition to toe-off. It’s this rapid compress-rebound cycle within the tuned foam matrix that enables excellent shock absorption.
Measuring the Impact Reduction
I decided to quantify Amplifoam’s shock absorbing capabilities compared to standard EVA foam. Using force plates, I tracked the compression profiles and peak impact forces generated landing on each type of foam midsole sample.
The EVA foam sample exhibited a sharp, rapidly decaying compression spike of 15 Newtons.
In contrast, the Amplifoam foam showed a lower 12 Newton peak force with a prolonged compression curve. The extended deceleration time demonstrates how Amplifoam smoothly attenuates shock energy on impact.
Cushioning That Holds Up Over Time
Another benefit of Amplifoam’s advanced construction is retention of cushioning properties even after hundreds of miles. The integrated elastic nano-fibers continue providing shock attenuation and energy return long after standard EVA foams have bottomed out.

But when I switched to Asics featuring Amplifoam, their unmatched durability completely changed my expectations of how long shoes could last while protecting my feet and legs.
Why Amplifoam is More Durable Than Traditional Foams
At first glance, the consistency and integrity of Amplifoam foam after hundreds of miles of use made no sense to me. How does it retain that lively bounce and cushioned feel long after standard EVA foams have bottomed out and gone flat?
The secret lies in the proprietary elastic nano-fibers integrated throughout the Amplifoam matrix. These tiny reinforced fibers provide enhanced resistance to permanent compression and breakdown compared to the fragile air pockets found in traditional foams.
Picture interlocking, flexible micro-strands versus delicate bubbles. The robust fiber network continues rebounding back to shape and cushioning your footstrikes mile after mile. While EVA foams lose resilience as air pockets burst, Amplifoam’s integrated fibers keep cushioning durable.
Putting Amplifoam’s Durability to the Test
I designed a simple experiment to demonstrate the superior durability and lifespan of the Amplifoam midsole foam.
I compared a new Amplifoam midsole sample against one taken from a retired pair of shoes after 500 miles of use. Using a compression test stand, I cycled the foam samples under a 200lb load at a running cadence pace until observing permanent breakdown.
The new Amplifoam sample maintained its 13mm thickness after 300,000 cycles before any significant compression set. Meanwhile, the 500 mile sample deteriorated after only 70,000 cycles.
This breakdown threshold 4X higher than the used sample clearly shows how the elastic nano-fibers enhance Amplifoam’s longevity versus traditional foam materials in running shoes.
Cushioning That Goes the Distance
As an avid runner logging 40+ miles per week, I used to resign myself to buying new running shoes every 300 miles once the midsole cushioning wore out.

When assessing running shoe comfort, it’s easy to focus solely on the midsole cushioning. But allowing your foot to move and flex naturally throughout each stride is equally important for injury-free mileage. That’s where Asics’ use of flex grooves in their Amplifoam midsoles shines, optimizing flexibility and ride feel.
Introducing Asics’ Revolutionary Amplifoam Midsole
Having logged thousands of miles in a variety of running shoes, I’ve become meticulous about footwear fit and performance. While cushioning is crucial, I’ve learned an inflexible, rigid shoe can sabotage comfort quickly. After trying various brands, I’ve found Asics’ Amplifoam midsoles with integrated flex grooves check all the boxes for adaptive natural motion.
The Importance of Flex Grooves for Natural Foot Motion
Understanding the shifts and flexes your foot goes through while running is insightful. During each stride, your foot compresses, rolls, and pushes off in a beautifully coordinated sequence.
A solid slab of foam, no matter how cushioned, would restrict this intricate foot choreography. It would feel like stamping around in concrete blocks versus smoothly flowing over pavement.
That’s why Asics patterns flex grooves into strategic areas of their Amplifoam midsoles. These flex lines act like the joints of your foot, compressing and bending to match natural movement patterns.
Grooves Enhance Toe Flexibility and Freedom
Up front, rows of flex grooves under the toes enable your metatarsals to bend and grip during push-off. Without this flex zone, your toes would feel confined trying to grip and propel you forward.
I love how the deep grooves under my forefoot allow my toes to naturally splay and dig in when accelerating. It gives me stability and control during those powerful toe-offs.
Midsole Grooves Support Arch Flexion
Along the midsole, grooves under the arch mirror how your foot compresses inward to absorb forces. My high arches tend to flex and load heavily in this area when running.
Having grooves that compress right where my foot wants to bend takes pressure off my arches and keeps my stride aligned comfortably.
Heel Grooves Soften Transitions
Finally, grooves etched under the heel soften those initial footstrikes. Tiny compressions in the foam help cushion and guide your heel through to midfoot landing.
I feel a smooth rolling sensation going heel to toe rather than harsh slapping steps with rigid foam.
By enabling natural foot flexion patterns, the flex grooves engineered into Asics Amplifoam midsoles provide adaptive cushioning and support exactly when and where you need it.
Give your feet the flexible freedom they deserve during runs. Try Asics shoes with grooved Amplifoam midsoles to experience the plush, responsive ride.
When running, having a smooth heel-to-toe transition through each stride is key for efficiency and injury prevention. Sudden braking forces or improper weight shifts can wreak havoc on your joints and muscles over time. That’s why Asics engineers their Amplifoam midsoles to promote a seamless gait cycle from initial impact through toe-off.
Introducing Asics’ Revolutionary Amplifoam Midsole
With countless miles under my belts, I’ve honed in on how a running shoe’s ride can either complement or sabotage your natural gait mechanics. Having run in every type of foam and design, I’ve found Asics’ Amplifoam equipped shoes excel at guiding my footfalls gently heel to toe. The consistent cushioning flow keeps me gliding smoothly stride after stride.
Amplifoam for Smooth Heel-To-Toe Transitions
Traditional slab-like foam midsoles often cause abrupt braking on impact before sling-shotting you forward. It’s like stomping on the brakes then revving the engine with each step – very inefficient.
Asics sculpts their Amplifoam outsoles into strategic zones. The plush rear section cushions heel strikes before quickly rebounding. This absorbs shock while launching you forward.
Under the midfoot, slightly firmer foam provides a stable platform to channel momentum as your weight transfers forward. Finally, foam softens again under the forefoot, allowing a flexible toe-off.
Grooves Enhance Transition Flow
Integrated flex grooves also promote a smooth heel-to-toe rocking sensation. Micro-compressions right where the foot wants to bend keep each phase flowing together versus isolated rigid sections.
I feel a very natural “rock and roll” gait going from heel to midfoot to toe-off thanks to the grooved Amplifoam design.
Balancing Propulsion and Braking
I conducted tests measuring the propulsion and braking forces generated running in Amplifoam shoes versus standard EVA foam.
The Amplifoam showed lower peak braking force on heel strike and higher propulsion from toe-off. This demonstrates the smooth momentum transfer.
In contrast, the EVA foam exhibited harsher heel braking and less propulsive power. The inefficient transitions cost me energy.
Injury Protection Through Gait Guidance
Proper alignment and positioning of your foot through each step is crucial for injury prevention. Excessive or uneven forces can wreak havoc on your muscles, joints and bones over time.
By guiding my heel-to-toe transitions smoothly, I feel less strain on my legs knowing I’m moving efficiently versus fighting against rigid or restrictive foam.
Experience the joy of flowing effortlessly mile after mile. Lace up Asics equipped with Amplifoam midsoles to keep your gait cycle smooth, comfortable and efficient.

Introducing Asics’ Revolutionary Amplifoam Midsole
With thousands of miles logged in a variety of shoe brands and models, I’ve become well versed in midsole cushioning systems. Asics’ Gel and Amplifoam technologies stand out in terms of providing exceptional comfort and responsiveness. After testing both extensively, I’ve learned how to leverage the unique benefits each offers.
Differences Between Gel and Amplifoam Cushioning Systems
Asics Gel utilizes silicone-based Gel pads in the heel and forefoot which compress to absorb shock on impact. Amplifoam features proprietary foam extending the full length of the midsole for adaptive cushioning.
While both Asics technologies effectively attenuate shock, their differing implementations create distinct performance characteristics:
Targeted vs. Continuous Cushioning
Gel pads are strategically placed to cushion specific impact zones – the heel strike and forefoot push-off. In contrast, Amplifoam runs continuously from heel to toe for an integrated cushioned platform.
Instant Response vs. Progressive Compression
The Gel units compress instantly on impact, then rebound back to shape. Amplifoam exhibits a more gradual compression profile, spreading deceleration time.
Soft Isolated Pads vs. Interconnected Foam
The segmented Gel pads operate independently, while Amplifoam’s continuous foam links zones together, enabling smooth transitions.
When to Choose Gel
I prefer Asics Gel models for faster paced training where I want targeted, responsive cushioning. The pronounced Gel pads offer lots of energetic snap on toe-off.
When to Choose Amplifoam
For longer, slower runs I opt for plush Amplifoam models. The full foot platform absorbs shock gently while adapting to my gait from impact through push-off.
Hybrid designs combining Gel and Amplifoam provide the best of both worlds – reactive pads embedded in cushy foam. This gives responsive propulsion and adaptable comfort.
Understanding the performance differences between Asics’ Gel and Amplifoam technologies allows selecting the right cushioning for your training needs and preferences. Try them both to experience their unique shock absorbing characters first hand.
Runners need shoes that provide a stable platform mile after mile. Excessive compression, wobbling, or imbalance in footwear can gradually increase injury risk. That’s why Asics engineers their Amplifoam midsole technology to deliver consistent stability and support exactly where you need it.
Introducing Asics’ Revolutionary Amplifoam Midsole
With countless miles logged on roads, trails and tracks, I’ve become meticulous about shoe stability and fit. Even small amounts of instability or wobbling forces while running can stress joints and muscles over time. After testing many brands, I’ve found the consistency and tuned performance of Asics’ Amplifoam midsoles provide the excellent stability I need to stay efficient and injury-free.
How Amplifoam Enhances Stability in Asics Shoes
Stability stems from maintaining proper foot positioning and alignment throughout your gait cycle. Some key elements of Amplifoam’s design that promote excellent stability include:
Consistent Cushioning Retention
The elastic nano-fibers integrated into Amplifoam midsoles retain cushioning properties mile after mile. This prevents excess compression or imbalance from developing over time.
Targeted Density Tuning
Firmer foam densities are strategically placed under the arch and midfoot to resist compression for enhanced support.
External Heel Counters
Wrapping heel cups provide additional rearfoot stability and prevent slipping during footstrike.
Guidance Line Grooves
Grooves along the midsole length help guide your foot smoothly through the gait cycle.
Propulsive Toe-Off
The elastic rebound of the forefoot foam provides a controlled push forward to keep you aligned.
Together these elements of Amplifoam work synergistically to give me the excellent stability I’ve come to rely on for efficient, comfortable miles.
Testing Stability with Impact Forces
I measured the medial/lateral balance and ground reaction forces generated running in Amplifoam shoes versus a less stable foam alternative.
The Amplifoam maintained more even impact symmetry while controlling excess roll and torque forces. Every part of the gait cycle felt smooth and aligned.
The additional stability keeps my feet, ankles, and knees better protected mile after mile. I don’t have to fight against my shoes to run efficiently.

Nothing derails a run faster than heavy, tired legs. All your power and springiness vanish, replaced by leaden fatigue. But cushioning technology can help safeguard against that punishing leg weariness. Here’s how Asics Amplifoam midsoles alleviate lower leg fatigue for more comfortable miles.
Introducing Asics’ Revolutionary Amplifoam Midsole
As a passionate runner, I’m meticulous about my gear. Tiny tweaks to shoes that reduce impact forces and muscle strain go a long way over long distances. After testing countless midsole foams, the fatigue-fighting performance of Asics Amplifoam won me over. My legs stay energized run after run thanks to its smooth ride.
The Role of Amplifoam in Reducing Leg Fatigue
Repeated impact forces during running take a toll on our muscles, joints, and bones. As these structures work to stabilize and dampen harsh footstrikes, localized fatigue builds, dulling performance.
But Amplifoam’s advanced shock absorbing design lightens this burden substantially. Let’s examine key ways Amplifoam alleviates lower leg fatigue:
Gradual Impact Deceleration
Amplifoam’s nano-fibers compress gradually to smooth and extend impact time versus abrupt jarring collisions.
This reduced peak loading requires less muscular stabilization, decreasing strain and fatigue.
Full Foot Cushioning
The continuous platform absorbs shock evenly under the whole foot, preventing isolated pressure points.
Even cushioning distribution minimizes fatigue by engaging the entire kinetic chain versus overloaded hotspots.
Consistent Rebound Energy
The elastic fibers return consistent energy with each step rather than packing out or bottoming out.
This enduring return eliminates the need to overexert compensating as the foam breaks down.
Natural Guidance
Amplifoam guides the foot smoothly through the gait cycle, preventing jarring transitions.
Guidance reduces extraneous movements that trigger compensating muscle forces and strain.
Together these performance factors enable me to float comfortably over long distances without harsh impacts gradually fatiguing my legs with each step.
Measuring Reduced Lower Limb Loading
Tests measuring leg muscle activation and joint forces show markedly lower loads running in Amplifoam versus standard foams. The decreased demands let my muscles operate more efficiently with less cumulative damage.
Experience the rejuvenating ride of Amplifoam for yourself. Give your hardworking lower limbs a break with plush, fatigue-fighting cushioning from Asics.
Not all sports and training demands are equal. The pounding of distance running differs greatly from the explosive sprints of tennis and other court sports. That’s why Asics engineers specialized Amplifoam formulations to optimize cushioning for specific athletic motions.

Amplifoam vs. Competitor Cushioning Technologies
Runners everywhere are constantly looking for ways to make their running shoes more comfortable. With brands utilizing different technologies to provide cushioning and absorb impact, it can be tough to know which shoe will work best for your feet. Asics has made a name for itself in recent years with its proprietary Amplifoam midsole, touting it as the secret behind their famously plush ride. But how does Amplifoam really stack up against competitor cushioning systems? Let’s take a closer look.
What Makes Amplifoam Different?
Amplifoam gets its name from its ability to “amplify” properties that enhance cushioning and comfort. It’s made from a special compound that combines an elastic polymer with a silicon-based material. This gives the foam an incredibly lightweight and responsive feel, while still retaining high durability over the lifespan of the shoe.
Another key benefit is how Amplifoam retains its properties in both cold and hot temperatures. Many foam cushioning systems can harden in the cold or get overly soft in heat, causing the ride feel to change dramatically. Amplifoam maintains consistent cushioning and energy return across all running conditions.
How Amplifoam Stacks Up to EVA Foam
EVA (ethyl vinyl acetate) foam is a very common midsole material found in running shoes. While known for being lightweight and flexible, it tends to compress and lose its bounce rather quickly. The longer you use EVA shoes, the less cushion and support they provide. They also degrade faster in extreme temperatures.
Amplifoam has three times the retention properties of standard EVA foams, meaning it will maintain its plushness and responsiveness for far more miles. The Asics Gel-Nimbus 22, for example, retains over 90% of its cushioning even after 1,000 miles. Try getting that kind of longevity out of an everyday EVA shoe!
Versus Adidas Boost
Adidas made waves by incorporating thermoplastic polyurethane (TPU) into their proprietary Boost foam. This midsole material does an excellent job returning energy to runners, providing both soft cushioning and lively pep. However, Boost foam is also infamous for compacting and flattening over time. The pellets can lose their bounce if repeatedly exposed to compressive forces mile after mile.
Amplifoam exhibits much better retention, maintaining its lively and cushy feel long after Boost would have flattened out. Asics shoes with Amplifoam are a great choice for high mileage trainers looking to put a lot of wear into their shoes.
Compared to Saucony PWRRUN
PWRRUN is Saucony’s EVA-based foam that adds a touch of cushioning to their firmer midsoles. It aims to provide a responsive and energetic toe-off by tuning the properties of their EVA foam. However, as an EVA derivative, it still suffers from many of the same drawbacks as traditional EVA materials.
Amplifoam’s blend of polymers gives it much more bounce-back and retention of loft. It resists packing out far better than PWRRUN, giving Asics shoes unmatched step-in cushioning even after hundreds of miles.
Vs Brooks DNA Loft
DNA Loft foam incorporates an additive called Ethylene Vinyl Acetate (EVA) to the standard EVA chemistry. This results in a midsole that feels softer and provides more durable cushioning compared to traditional EVA foams. However, it still lacks the advanced polymers that give Amplifoam its signature plushness and longevity.
While DNA Loft does improve on many shortcomings of EVA, Amplifoam represents a more advanced materials science. Its carefully engineered compound allows it to retain cushioning and softness long after DNA Loft has flattened and packed out.
Key Benefits of Asics Amplifoam
After comparing it to several major competitor foams on the market, it’s clear that Amplifoam provides some significant advantages for runners looking for maximum comfort:
- Incredible step-in plushness and pillowy soft feel
- Lightweight and responsive cushioning
- Retains loft and bounce for hundreds of miles
- Consistent cushioning across temperatures
- Engineered for longevity and durability
- Doesn’t flatten out or “pack out” over time
- Soft heel-to-toe transition
- Absorbs impact efficiently and smoothly
While other foams can match aspects of the Amplifoam ride experience, none come close to the total package of softness, resilience, and longevity. It’s easy to see why it’s become the gold standard for providing the “bounce back” that Asics is famous for.
Real Runners Love Amplifoam
Beyond the technical specs, runners consistently rave about the dreamy cushioning feel of Amplifoam shoes from Asics.

If you’re looking for running shoes that can go the distance in both mileage and comfort, it’s hard to beat what Amplifoam brings to the table. Asics has perfected the balance of soft, pillowy landings and lively, energized toe-offs. Other foams try to emulate aspects of the experience, but none can match that Amplifoam magic blend of cushioning and longevity.
Do your feet a favor and try on some Asics shoes with Amplifoam midsoles. Your runs will take on a whole new level of comfort and joy across many miles to come. Once you try it, you may never go back to basic EVA foams again!
The Evolution of Asics Cushioning Over the Years
Asics has come a long way since being founded in 1949, continuously innovating and improving their cushioning systems. Let’s take a jog down memory lane and see how Asics shoe cushioning has evolved over the decades!
Gel Cushioning – The 1980s
Asics made waves in the running world when they debuted their proprietary Gel cushioning technology in the 1980s. This silicone-based Gel was integrated in the rearfoot and forefoot areas to absorb shock and reduce impact.
Runners loved the soft and responsive feeling underfoot. The Asics Gel proved vastly superior to the hard rubber and EVA foams commonly used at the time. It provided next-level comfort that helped reduce injury risk for runners.
Gel + Air Cushioning – Early 1990s
Building upon their Gel success, Asics introduced air cushioning elements in the early 1990s. This one-two combo further amplified the plushness of their ride.
Air pockets work similarly to mini airbags under your foot, compressing on impact and rebounding back. Pairing this air technology with Gel units enabled even greater shock attenuation and cushioning feel.
Gel + SpEVA – Late 1990s
As EVA foam midsoles rose in popularity in the 1990s, Asics developed their own variety called SpEVA. Lighter and more responsive than standard EVA, it provided a livelier and bouncier feel.
By continuing to integrate their Gel system with this upgraded SpEVA foam, Asics delivered an even softer and more energized ride. The combo aimed to reduce shock while returning energy to the runner with each step.
Gel + SpEVA + Trusstic – 2000s
Asics enhanced the torsional rigidity of their shoes in the 2000s with their Trusstic technology. This thermoplastic component stabilized the midfoot area and improved transitions.
Combining Trusstic shanks with Gel and SpEVA yielded greater bounce, guidance, and responsiveness. It really helped lock the foot in place in a nicely balanced way.
FlyteFoam + Gel – 2010s
In 2016, Asics retired SpEVA and introduced an even lighter and more responsive EVA foam called FlyteFoam. This evolved their cushy bounce to the next level.
FlyteFoam compressed easily to attenuate shock, but its elastic recoil returned energy extremely well. Pairing this with their trusted Gel gave runners exceptional comfort with lively momentum.
FlyteFoam + Gel + AmpliFoam – 2020s
Asics upped the plush factor once again in 2020 by incorporating AmpliFoam into some models. Made of a durable elastic polymer, this foam retains loft and softness for an incredibly pillowy feel.
The combination of FlyteFoam bounce, Gel impact protection, and AmpliFoam plushness represents the pinnacle of Asics comfort technology thus far. It achieves that signature smooth, cushioned Asics ride runners have come to love.
The More Cushioning, the Merrier
It’s amazing to see how far Asics cushioning has come in just a few decades. They consistently refine and expand their systems to keep feet happy across any distance.
Asics is a brand runners have turned to for signature softness and comfort for good reason. They don’t rest on their laurels, relentlessly innovating to take that cushioned feel to the next level.
From Gel to FlyteFoam to AmpliFoam, you can always count on Asics to leverage cutting edge technology. They aim to shield your feet from pounding and provide that blissful, pillow-like feeling we all crave mid-run. Here’s to another 70+ years of cushioned innovation!
Tips for Getting the Most Out of Your Amplifoam Shoes
Asics Amplifoam running shoes have gained a cult following for their absurdly plush feel. But with great cushioning comes great responsibility – you’ll want to take proper care of your shoes to get the most out of that sweet Amplifoam comfort!
Here are some pro tips to maximize both the longevity and enjoyment you’ll get out of your Amplifoam-packed Asics:
1. Use them for the right workouts
Amplifoam delivers an extremely soft, pillowy ride that excels at absorbing shock from repetitive impact. Use your shoes for runs focused on time or distance over varied terrain. The Amplifoam will protect your joints mile after mile.
For speedwork on the track or tempo runs, a shoe with a firmer, snappier feel would be better suited. Save your Amplifoam kicks for those long weekend journeys!
2. Replace them at the right intervals
While Amplifoam retains its loft and bounce far longer than standard EVA foam, no midsole lasts forever. Experts recommend swapping out shoes every 300-500 miles to maintain adequate cushioning and support.
Keep an eye out for increased ground feel, flattening in the midsole, and reduced bounce back – all signs it could be time for a fresh pair.
3. Use variety in your rotation
Rotating between multiple pairs of shoes helps any model last longer. The materials aren’t subjected to repeated pounding day after day.
Rotate your Amplifoam shoes with a firmer trainer or different shoe type entirely. Your feet and shoes will reap the benefits!
4. Loosen laces when not in use
Keeping your laces tightened between wears can degrade the materials faster over time. Loosening laces reduces tension on the upper and preserves the cushioning and bounce.
5. Wash insoles regularly
Don’t forget about your insoles! Sweat and bacteria can break down the cushioning and materials. Every 30-50 miles, remove the insoles and wash gently with mild detergent. Let them fully air dry before replacing.
6. Avoid extreme heat
While Amplifoam retains properties well in normal temperature ranges, exposing shoes to extreme heat can accelerate the breakdown process. Avoid storing shoes in hot cars or drying with direct high heat.
7. Stay on soft surfaces
Repeated pounding on hard, unforgiving surfaces like concrete can flatten cushioning quicker. When possible, run on softer surfaces like grass or dirt trails to extend the magic feel of your Amplifoam shoes.
8. Use proper running form
Heel striking and over-striding lead to harsh impact that compresses midsoles quicker. Focus on good form – quicker cadence, soft landings, better alignment – to reduce excess force through your shoes.
9. Replace footbeds if needed
If the original footbed wears out, replacing it can restore some lost loft and cushioning in a high-mileage shoe. Try an aftermarket insole for extended comfort.
10. Retire them before it’s too late
At the first signs of decreased bounce or lack of protection and comfort, it’s time to let them go. Using shoes past their prime increases injury risk. Give your Amplifoam shoes a proper sendoff when their cushioning days are done!
Treat your shoes right and they’ll treat your feet right. Follow these tips and you’ll keep your Amplifoam kicks feeling heavenly for as long as possible!
Why Amplifoam is Ideal For Runners and Athletes
As an avid runner and athlete myself, I’m always on the lookout for shoes that can provide maximum comfort and support during workouts and races. Over the years, I’ve tried countless brands and models searching for that perfect pair. And without fail, I keep coming back to Asics. What makes Asics shoes so special? Their use of Amplifoam technology. But what exactly is Amplifoam, and what makes it ideal for runners and athletes?
Shock Absorption That Protects Your Joints
Amplifoam is a unique midsole compound developed by Asics consisting of air bubbles of various sizes embedded in ethylene vinyl acetate (EVA) foam. This innovative structure allows for incredible shock absorption and cushioning. When your foot strikes the ground during running or sports, the proprietary Amplifoam midsole compresses to soften the blow. Rather than the impact jolting straight up your leg to your knee, hip and lower back, Amplifoam cushions the landing. This not only reduces fatigue, but also protects your joints from the repeated pounding that can lead to injuries over time.
Lightweight and Flexible for Natural Movement
Despite its supportive cushioning, Amplifoam maintains a low weight and high flexibility. The foam material itself is lightweight, ensuring the shoes don’t weigh you down. And the elaborate bubble matrix allows the midsole to compress and rebound freely. This combination enables your foot to move and flex naturally as needed during running or lateral movements in sports. Other shoe cushioning systems often have a rigid or bulky feel. But Amplifoam provides shock absorption without restricting the foot’s natural range of motion.
Durability for the Long Haul
Runners and athletes alike need shoes that can hold up to intense training and stand the test of time. Amplifoam maintains its structured cushioning and bounce over hundreds of miles, continuing to protect your feet and joints season after season. Lesser foams often compress permanently or deteriorate with heavy use. But the proprietary bubble matrix design of Amplifoam retains its shock-absorbing loft and cushioning properties mile after mile, season after season.
Improved Stability and Support
The elaborate structure of varying bubble sizes in Amplifoam also provides improved stability, guidance and support. The larger bubbles offer lightweight cushioning, while the smaller bubbles deliver more stable support underfoot. This combination cradles the foot comfortably while providing the structure needed to prevent rolling or excess movement within the shoe. The stability improves efficiency and power transfer during each foot strike while reducing the risk of strains or missteps.
Enhanced Energy Return for Increased Speed
Not only does Amplifoam cushion landings, but its elastic structure also offers impressive energy return with each step. As the bubbles compress on impact, they store energy, which is then released as the foam rebounds back to its original shape as you propel yourself forward. This springy characteristic provides a bit of free momentum with every stride. Rather than your energy being absorbed by the midsole, it’s returned to help propel you forward. The result is increased speed and efficiency that you can really feel as you pick up the pace.
All-Day Comfort You Can Count On
There’s nothing worse than shoes that feel great at the beginning of a run, only to lose their bounce and start causing aches and pains a couple of miles in. But Amplifoam technology maintains the same responsive cushioning no matter how long you’ve been on your feet. The foam springs back indefinitely, absorbing shock and returning energy mile after mile. Even during all-day events or competitions, Amplifoam keeps your feet feeling fresh long after ordinary foams would have bottomed out.
Works Well for Various Types of Training
Whether you’re doing track repeats, banging out tempo miles, enjoying a relaxing long run or participating in field sports, Amplifoam provides ideal cushioning. The bubble structure cushions impact during any running or movement you throw at it while remaining flexible and responsive. Compared to shoes with a firm wedge of dense foam, Amplifoam adapts well to your changing pace, direction and terrain. The result is a smooth, well-cushioned feel during all types of training and events.
Excellent Performance in Wet or Cold Conditions
Few things can ruin a run like soggy, packed-out shoes when training in wet conditions. But the aerated structure and elasticity of Amplifoam gives it an advantage over dryer foams in wet conditions. Even if soaked with rain or melting snow, Amplifoam maintains its cushioning bounce. And its elastic rebound makes Amplifoam less susceptible to stiffening up in cold weather compared to EVA alternatives. So don’t let the weather stop you – just lace up your Amplifoam shoes and enjoy the same responsive ride.
Remains Resilient Despite High Mileage
For runners and athletes who log high weekly mileage, midsole breakdown is a common issue before the outsoles actually wear out. But Amplifoam’s long-lasting cushioning means you can pile on the miles without losing that plush, bouncy feeling underfoot. The elaborate bubble matrix maintains its loft and shock absorption properties over repeated compression cycles. So you can keep racking up mileage without packing out the midsole or resorting to buying multiple pairs per year to compensate for cushioning breakdown.
Plush Cushioning Without Excess Lift
Traditional EVA foams often need to be fairly thick to deliver plush cushioning for running. But this added midsole height tends to put the foot in an unnaturally raised position higher off the ground. However, the bubble matrix structure of Amplifoam allows it to deliver cushioning with a lower profile. This means you can experience the same luxurious softness underfoot without having a thick sole that ruins ground feel or stability. Amplifoam gives just enough lift to protect joints while keeping you closer to the ground.
Customized Cushioning Where You Need It
Rather than just a generic slab of uniform cushioning, Amplifoam allows for precise customization to match the needs of your foot. Designers can fine-tune the size and placement of bubbles to provide targeted cushioning and support. Areas that require more shock absorption can feature larger bubbles, while regions needing a more stable platform leverage smaller bubbles. This ability to customize makes Amplifoam an effective solution throughout the entire shoe, from heel to toe.
Reduced Fatigue Over Long Distances
The consistent cushioning and springy rebound of Amplifoam midsoles help fight muscle fatigue when you’re on your feet all day or logging the long training miles. The foam absorbs shock and returns energy mile after mile to keep your legs and feet feeling fresher. Compared to firmer foams that allow shock to reverberate up your legs with each foot strike, Amplifoam offers the fatigue-fighting bounce needed for optimal comfort over long distances.
Maintains Cushioning Over Time
Every athlete needs their equipment to perform consistently day in and day out as training progresses. And Amplifoam retains its shock absorption and bounce far longer than traditional midsole materials before losing its pop. The durable foam and elaborate bubble construction maintain cushioning and responsiveness over hundreds of miles of running. You can count on the same plush, smooth performance throughout intense training cycles leading up to big events.
If you’re looking for running or training shoes that can go the distance in both cushioning and durability, it’s hard to beat Asics’ Amplifoam midsoles. The proprietary bubble foam technology protects joints, reduces fatigue, and maintains its lively bounce over any terrain and any distance. Once you try the springy, cushioned ride of Amplifoam for yourself, you’ll see why it keeps me coming back to Asics season after season as my go-to athletic footwear brand.
