The Science of Air
Our inserts combine specialized polymers, supportive foam, and pressurized air to provide tailored support and flexibility.
Unlike conventional inserts, our products are tuned through varying inflation pressures, optimizing energy absorption based on your size and activity level. This unique design ensures both durability and comfort. Traditional inserts are made with foams and gels, which don't have the same elasticity response as air. Think of it like a spring - every time it's compressed and decompressed, it returns to its shape. Foams and gels break down and lose their cushioning and support. Air doesn't.
One of the most revered laws of physics is Sir Issac Newton’s 3rd Law of Motion that states, “For every action there is an equal and opposite reaction”. As a result, with every step you take, a “Ground Impact Force” is directed through your feet and into your body which absorbs this energy. The amount of force with every step depends upon your weight and level of activity.
Numadx Inserts are based on this same law - they are designed to absorb the maximum amount of energy possible and reduce the amount of energy transferred back into your body. This reduction in energy transfer provides a reduction of impact energy entering your feet, ankles, knees, hips and lower back providing an immediate reduction in pains associated with these ground forces.

Pressure Tested
We’ve tested our materials through millions of cycles in our laboratory, ensuring they deliver unmatched durability and performance. Unlike foam and gel-based shoe inserts, which can compress and degrade over time, Numadx inserts harness the power of air, a superior medium for energy absorption and distribution. Pneumatic materials provide dynamic support by adjusting to your every step, reducing impact forces on your joints and enhancing energy return for a more efficient stride.
Air’s inherent elasticity offers a consistent and customizable cushioning experience, adapting to your weight, activity level, and unique biomechanics. The result? Reduced fatigue, better shock absorption, and an overall lighter, more responsive feel.
