Air cushion, a technology commonly known as air, was invented by Frank Rudy, an engineer of NASA in the late 1970s, and Nike bought the patent, thus rewriting the history of sports shoes.

1, air sole
Air-Sole is a "moderate" air cushion, which has a relatively balanced performance in buffering capacity, stability and reaction speed.
2, Nike air zoom
The name of nike air zoom series comes from ——zoom air, a unique air cushion unit spontaneously developed in its technical configuration. Zoom air is an air cushion with a thickness of only 4-8 mm, in which three-dimensional fiber fabric is fixed to keep its flat shape (otherwise it will "swell" into a ball), and the air pressure is 20PSI.
Zoom air not only provides shock absorption effect, but also has excellent site feeling, sensitive rebound effect and excellent acceleration performance, so it is widely used in perimeter basketball shoes (such as Flight series and AJ series) and speed running shoes (such as air zoom miler series).
3. Nike Air Max
At first, it was U-shaped, and later it developed into Air Max2 with multiple closed air chambers and Tube Max air in the shape of trachea. It has multi-range and multi-pressure, with 5PSI in low pressure area and 25PSI in high pressure area. Max air has a strong cushioning ability, which can provide proper protection for feet and even knee joints, but it pays the price of the loss of machine power. Mostly used for inside players.
