Nike

Nike Air is pressurized air inside a tough, yet flexible bag. These Air Sole units are located in the midsole beneath the heel, forefoot or in both locations. The Air Sole unit compresses to reduce the force of impact and then immediately recovers to its original shape and volume, ready for the next impact.

The 4 main benefits of Nike Air:

Lightweight - By displacing heavier midsole materials with Nike Air cushioning, we can reduce the weight of the shoe without sacrificing performance. This is important because the lighter the shoe, the less energy the athlete must expend during performance.

Versatile – This is important because different athletes in different sports require different performance characteristics. Nike Air cushioning can be tuned to meet the exact specifications of athletic performance.

Cushioning – As the foot strikes the ground, Nike Air cushioning "gives" or absorbs the impact forces and allows the muscles, joints and tendons to be protected. And it will immediately return to its original shape ready to protect the body against the next impact force. As a result, the athlete is able to protect their body from fatigue and stress.
