How 4D Midsoles Are 3D Printed for Precision
Adidas shattered the norms of footwear manufacturing when they unveiled their revolutionary 4D line of running shoes featuring 3D printed midsoles. This innovative manufacturing process allows for unparalleled precision in crafting a midsole that provides the exact cushioning and support needed for an individual runner’s needs.
Traditionally, shoe midsoles have been made by injecting foam into a mold. While this allows for mass production, it lacks the customization that 3D printing makes possible. Adidas took notice and acquired a company called Carbon that specializes in using light and oxygen to 3D print with unprecedented intricacy in a process called digital light synthesis.
This groundbreaking technique works by using digital light projection, oxygen permeable optics, and programmable liquid resins to produce high-performance elastomers. It enables the creation of tailored geometric lattice structures in the exact contoured shape of a runner’s foot for the ultimate in precision and comfort.
Here’s a look at how the 4D midsoles are produced using this advanced 3D printing technology:
Step 1: Foot Scan
It all starts with getting detailed data on the runner’s foot. Adidas stores use a foot scanner to get precise measurements and contours of the foot shape. Over one million data points are captured to map out the foot’s exact topography.
Step 2: Custom Design Software
That data is then fed into Adidas’ custom design software that uses proprietary algorithms to translate the foot scan into a tailored lattice midsole structure. Engineers input data on factors like the runner’s gait cycle, weight, and personal cushioning preferences to further customize the design.
Step 3: Resin Production
With the custom lattice digital model complete, the design file is sent to the 3D printer where the magic happens. The printer contains a vat of liquid polyurethane resin that is precisely exposed to UV light to produce the programmed design one layer at a time.
Step 4: 3D Printing
An oxygen permeable window sits below the photopolymer resin vat and a UV light source shines up through the window. The light source flashes in ultra-fine pixel sizes as small as 140 microns. Wherever the light shines, the resin solidifies. Layer by layer, about 24,000 layers per shoe, the resin hardens into the custom lattice structure.
This additive manufacturing method allows for incredibly intricate designs not possible with traditional foam mold injection. The resulting midsole has a consistent honeycomb-like pattern tailored to match each runner’s foot.
Step 5: Washing and Curing
After printing, any excess liquid resin is drained away and the midsole is washed. It is then cured in an oven-like machine which hardens the material completely using additional UV light and heat. The finished midsole is ready to be incorporated into the rest of the shoe.
Step 6: Performance Testing
Before going to market, samples of the 3D printed midsoles are rigorously tested for compression, durability, and energy return. This ensures the precision promise of 4D technology delivers real performance benefits when the shoes hit the road.
Step 7: Upper Assembly
The high-tech midsole is combined with the shoe upper and other components to complete the shoe. Each 4D-printed midsole is matched to its unique upper before going out for delivery to the runner who had their foot scanned.
The Adidas 4D printing process represents a revolutionary leap forward in running shoe design. By crafting lattice midsoles tailored to a runner’s exact foot shape, gait cycle, and cushioning preferences, Adidas has cracked the code of precision and customization.
Runners are experiencing the benefits, reporting improvements in fit, comfort, support, and energy return compared to traditional foam midsoles. And this technology has applications beyond running, providing customized cushioning for all kinds of athletic footwear.
The future looks bright, or rather, precisely pixelated with light. Adidas continues to refine 4D printing, unlocking the practically infinite possibilities of custom 3D printed midsoles. Each runner can have shoes engineered just for them, providing the holy grail of fit and feel. Thanks to light and oxygen, running in perfect precision is becoming a reality.

Uninterrupted Energy Flow
The uniform honeycomb design enables energy to flow freely from landing to push off for optimized running economy. There’s no wasted energy as the foam compresses and rebounds with your natural foot motions. Traditional midsoles with separated heel and forefoot cushions can’t achieve the same smooth energy transfer.
Targeted Stability Zones
While the overall lattice pattern is consistent, engineers strategically map thicker stability zones to areas that need extra support. This prevents excessive and uneven compression for balanced cushioning. Targeted reinforcement also aids medial and lateral stability to help limit overpronation.
Precision Lattice Calibration
The modular lattice structure can be finely calibrated to match a runner’s size, weight, gait analysis, and personal preferences. The digital light printing process allows for micro-adjustments to the exact thickness, geometry, and stiffness required for ideal shock absorption and propulsion.

By eliminating the need for separate midsole components like carrier plates and stability posts, the shoes shed unnecessary ounces. The efficient geometric lattice further minimizes material usage without compromising performance.
Unmatched Comfort
The full-length chassis is tailored to map every contour and dimension of your foot for a truly customized fit. This prevents slipping, rubbing, and hot spots. The consistent cushioning also reduces impact vibrations and joint strain compared to segmented midsoles.
Environmental Sustainability
Consolidating to one unified midsole piece has ecological benefits as well. Fewer materials and manufacturing steps results in less waste production. The shoes can also be fully recycled after use to recover and reuse the material rather than sending it to landfills.
Early 4D models like the AlphaEdge featuredfull chassis units, but they were fused from two separate 3D printed halves. Adidas pushed the design even further with shoes like the 4D Run 1.0 that boast a fully enclosed 4D chassis truly built as one unified component.
This seamless construction offers the height of running shoe innovation. Your foot rests in a precision cradle that works holistically to guide your natural motions. Every step flows effortlessly from heel strike through to push off for optimized form and reduced injury risk.
Adidas wasn’t content to just inject their lattice cushioning into the midsole. They reimagined what a running shoe chassis could be. The result is a perfectly calibrated 4D shell that seamlessly translates the sensory feedback from your foot into dynamic support. It takes running shoe customization and energy flow to the next level.
What About the Upper?
Of course, the upper design plays a critical role as well in completing the 4D experience. Key features include:

That’s what makes Adidas’s new 4D line so intriguing – it promises a customized running experience like we’ve never seen before.
Comparison to Other Popular Running Shoes
Traditional running shoes are made by injecting foam into a mold. But this process is imprecise. The molds have limitations, resulting in standardized shoes that don’t account for minute differences in runners’ feet.
Enter 3D printing. With Adidas’s 4D shoes, a digital light projection system prints liquid resin into thousands of lattice-like structures. This allows for precise tuning and customization, optimizing cushioning and support in ways never before possible.
While brands like Nike and Brooks also utilize 3D printing, Adidas takes it a step further with its proprietary 4D tech. This process enables more flexibility, responsiveness, and personalization than competitors’ existing 3D capabilities.
For example, Nike’s Flyprint tech has a “pixelated” feel since it stacks individual pieces together. Adidas’s liquid resin approach enables a smoother, more lifelike cushioning system. And brands like Brooks still rely heavily on foam injection to complement 3D printed elements. Adidas 4D is 100% printed.
In short, Adidas 4D allows for an unprecedented level of customization based on factors like foot shape, gait analysis, weight, etc. It’s a radically individualized approach vs the “one shoe fits many” strategy of older methods.
Revolutionizing the Running Experience
So how exactly does Adidas 4D provide such personalized performance?
It starts with fit. Using digital scans and motion capture technology, Adidas can analyze the intricacies of your individual foot to engineer a seamless upper constructed through 3D knitting and printing. The result is a breathable, flexible, and supportive fit that feels like a second skin.
Next is the light yet springy 4D midsole. Its lattice design allows for precision tuning of cushioning needs. Adidas can digitally craft areas of soft comfort for impact protection right where you need it, along with stable responsiveness for an adaptive heel-to-toe transition.
Together, these components create a sensation of almost running barefoot – with a natural foot strike and freedom of movement. But the shoes also provide guidance and protection to help avoid injury or discomfort. It’s the holy grail of running shoe design.
The Verdict: A Glimpse Into the Future
Adidas 4D is not cheap. The shoes retail for around $200 due to the advanced tech and custom manufacturing. And the 4D line is still limited to a handful of models. But there’s no denying this 3D printing process represents a huge leap forward.
For Adidas, the upside is clear – more personalized shoes mean happier runners and more sales. For us runners, 4D tech offers the promise of footwear that finally accounts for our specific needs. No more sore arches, slick heels, or dead toes after a run. Just the feeling of shoes tailor-made for our feet.

The 4D Line Provides a Unique Running Experience
While most major athletic brands are still relying on traditional foam and air cushioning for their running shoes, Adidas is forging a revolutionary new path with their 4D line. This innovative footwear uses a futuristic process called digital light synthesis to 3D print lattice-structured midsoles that are precisely tuned to each runner’s foot.
Rather than using generic mass-produced cushioning, 4D midsoles are customized based on data from thousands of foot scans and gait analysis tests. A proprietary algorithm then determines the optimal structure to provide targeted support and responsiveness where the individual runner needs it most. This biomechanical personalization leads to a running sensation that really has to be felt to be believed.
Unparalleled Energy Return
One of the major benefits 4D runners rave about is the exceptional energy return these shoes provide. The lattice design allows for carefully calibrated compression that minimizes impact shock while maximizing bounce back. When your foot strikes the pavement, the midsole deforms to cushion the landing then springs back energetically to propel you into your next stride.
Racers like marathon champion Diana Kipyokei praise the “pop” they feel in each forward-propelled toe-off while wearing 4D shoes. This exceptional energy return helps you maintain speed even late in grueling long distance races where legs and lungs are burning. Less energy lost with each footstrike equals more forward momentum for the 4D runner.
Uniquely Responsive Ride
In addition to their energetic snap, 4D shoes also provide a sensation of connectedness and control that runners love. The lattice design makes the cushioning incredibly responsive to each foot movement and flexion. There is no lag or delay between when your foot changes position or pressure and when the midsole reacts to stabilize or propel accordingly.
This hyper-responsive sensation gives 4D shoes almost a mind of their own, intelligently optimizing their support and flexibility to match the runner’s needs in real time. The smooth transitions and targeted stability let you ride the shoes with confidence and focus fully on picking up the pace.
Personalized Fit
While other performance running shoes use generic one-size-fits-all cushioning, each pair of 4D shoes is uniquely matched to the owner’s foot. Adidas accomplishes this through biometric scans and gait analysis. Thousands of data points on the specifics of your foot skeletal structure, pressure points, and running motion inform the lattice pattern printed into the 4D midsole.
This custom fit eliminates uncomfortable pressure points and provides stability precisely where you need it most. The 4D shoes become natural extensions of your own feet, moving seamlessly with them mile after mile. For runners who have struggled to find shoes that work with their biomechanics rather than against them, 4D tech is a revelation.
Endless Optimization
Because 4D midsoles are digitally printed based on algorithmic data patterns, Adidas can continually refine and enhance the shoe design without any manufacturing limitations. Even after you get your customized pair of 4D shoes, Adidas engineers are still working behind the scenes to analyze aggregated data from thousands of runners’ footsteps and mileage.
As the biomechanical dataset grows, the proprietary 4D algorithms become more intelligent and precise. Your next pair of 4D shoes will benefit from everything Adidas has learned since you first laced up. It’s a never-ending quest to engineer the perfect ride.
