The Science of Air
Numadx inserts are engineered with cutting-edge materials, combining specialized polymers, supportive foam, and the power of pressurized air to deliver unmatched support and flexibility. Designed to be tuned to your unique needs, they cater to people looking for support throughout the day as well as individuals looking for lasting relief from foot pain, joint pain, and back pain.
Unlike conventional foam or gel inserts that lose their shape and effectiveness over time, Numadx inserts are fully customizable. By adjusting inflation pressures, they optimize energy absorption and cushioning based on your size, activity level, and biomechanics. This innovative design not only enhances comfort but also ensures long-term durability, helping you move better, longer, and with less fatigue.

Pneumatic Cushioning
What is pneumatic cushioning technology?
Pneumatic cushioning is using compressed pressurized air to soften impacts and absorb energy. It's commonly found in products including “bubble wrap”, shock absorbers, pressurized car tires, and other advanced industrial cushioning applications. It's used in industries where impact protection, shock absorption, and energy return are important. Sounds a lot like when you move, huh?
Why Haven’t I Seen Pneumatic Cushioning in Other Footwear Products?
You actually have! The flagship technology of the world’s largest athletic shoe brand is a form of pneumatic cushioning. Numadx, however, is the first to move this technology out of the shoe’s midsole and position it closer to the foot as a removable insert. Putting the pneumatic cushioning closer to your foot provides superior benefits over burying the technology in the mid-sole.
Moving Better at every Step of the Way
How are Numadx Inserts Superior Over Foams and Gels?
Foams and gels lose their effectiveness over time, providing less cushioning and energy absorption compared to pneumatic cushions. They also break down more quickly, absorb moisture and bacteria with use, and are harder to optimize for individual sizes or activity levels. Numadx inserts, on the other hand, maintain long-term performance, resist moisture, and are tunable to meet the needs of each user. Foams and gels are a one-size-fits-all approach. Wouldn't you want something that's tuned to you?
Why Do Numadx Inserts Look Different from Other Products?
Let’s face it—most foam and gel insoles on the market look alike and offer similar benefits, which can be confusing for consumers. Numadx inserts stand out with their unique design: pressurized, flat, and low-profile. They’re made to fit between the removable insole and the midsole of your shoe, delivering an unmatched level of energy absorption and comfort.
Why Isn't There Any Fabric on the inserts?
We intentionally avoid adding fabric to our inserts to prevent common issues like foot odors and bacteria buildup caused by moisture. Instead, our inserts are made from thermoplastic polyurethane, a durable, antimicrobial material that resists bacteria and keeps your feet fresher, longer. By eliminating fabric, we ensure a cleaner, more hygienic experience with every step.
