The air logo on Nike shoes indicates that the product is equipped with Nike's famous shock-absorbing technology, which is an air cushion made of special gas and special air pressure.
The technology of air cushion, generally called Air, was created by Frank Rudy, an engineer at NASA, in the late 1970s. Nike bought the patent and from then on Rewrote the history of sneakers.

Classification
1. Air sole
Air-Sole has cushioning capacity, stability and response speed. The performance is relatively balanced in other aspects, and it is a "moderate" air cushion.
2. Nike air Zoom
The name of the Nike air zoom series comes largely from the unique air cushion unit developed independently in its technical configuration - zoom air. zoom air is an air cushion with a thickness of only 4-8mm. There is a three-dimensional fiber fabric fixed in it to maintain its flat shape (otherwise it will "bulge" into a ball shape), and the air pressure is 20 PSI.
Zoom Air not only provides shock absorption, but also has excellent court feel, sensitive rebound and excellent acceleration performance. Therefore, it is widely used in outside basketball shoes (such as Flight series, AJ series) As well as speed running shoes (such as air zoom miler series), etc.
3. Nike air Max
It was originally U-shaped, and later developed into the Air Max2 with multiple closed air chambers and the tracheal-shaped Tube Max air. It has multiple zones and multiple pressures. The air pressure in the low-pressure area is 5PSI, and the air pressure in the high-pressure area is 25PSI. Max air has strong cushioning capabilities and can provide proper protection for feet and even knee joints, but the price paid is a loss of mobility. Mostly used for inside players.
