What does the AIR brand in Nike mean? What brand is it?

1.AIR is not a brand, but a technology, which is a patent of Nike. 2. The words' AIR',' zoom' and' max' will appear on Nike shoes, indicating that there is' air' technology in these shoes. 3. Air is an air cushion. 4. Nike's air types are: Air sole, Zoom air and Max air. Total air volume and regulated air volume 5. The three most common types: 1. Airsole: Air cushion technology first developed by Nike. The principle is to inject gas into a tough synthetic rubber layer through high pressure and treat the gas injected into the rubber layer. It cannot pass through the outer rubber layer. Air-Sole is a "moderate" air cushion in terms of buffering capacity, stability and reaction speed. 2.Zoom air: Nike official website interprets it as an impact air cushion. Very thin, make feet closer to the ground and improve stability. It provides enough flexibility and cushioning. Personally, I feel softer and more comfortable than Max air. It is more suitable for light weight. 3. air maximum: air maximum 2 was initially u-shaped, and later developed into a multi-closed air chamber, which controlled the maximum air. It has multi-stage and multi-pressure, the air pressure in the low-pressure area is 5PSI and the air pressure in the high-pressure area is 25 psi. Max Air has a strong cushioning ability, which can provide proper protection for the foot and even the knee joint, but at the cost of losing the machine power. Mostly used for inside players.
