It means there is an air cushion in the shoe, and shox is also used to mean a compressed air column.

Max Air is the second air cushion launched by NIKE. It is improved based on the earliest AIR cushion launched by NIKE. It was launched in 1987 and used in the classic sneaker AIR MAX 1 of that year. The shoe was named AIR MAX 1 because it was the first pair of sports shoes equipped with MAX AIR air cushion.

MAX AIR air cushion will belong to the NIKE air cushion series. It uses gas to the limit and is the best protection system in the face of impact. Because when people’s feet repeatedly impact the ground during exercise, it will affect the body and sports performance. Cause a lot of damage, the MAX AIR air cushion can share the powerful impact of the athlete's load and give the athlete comprehensive protection.

Extended information

The air cushion technology developed by Nike from the first to the present.

1. Air sole

The earliest developed air cushion technology, the principle is to pour gas into a tough synthetic rubber layer at high pressure, and to control the gas poured into the rubber layer. Treat it so that it cannot penetrate the outer rubber layer.

Air-Sole has a relatively balanced performance in terms of cushioning capacity, stability and response speed, and is a "moderate" air cushion. The popular Air Jordan 1 uses this air cushion. Generally speaking, the Air sole is invisible and is embedded inside the midsole of the sneaker.

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 effect, but also has excellent court feel, sensitive rebound effect 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.

Nowadays, most of Nike’s signature sneakers for NBA stars use zoom Air! It provides cushioning while also giving enough elasticity. I personally think it is softer and more comfortable than Max air, and is more suitable for outside players who are not heavy and can start quickly.

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 on inside players and most running shoes.

4. Total air

The giant air cushion can be regarded as an enhanced version of Max air. The capacity and distribution area of ??the air cushion are larger, covering the whole palm, and the performance is the same as that of Max air No different. Mostly used in running shoes, all-around shoes, and inside basketball shoes. The last pair of NIKE shoes Yao Ming wore after entering the NBA (he later switched to Reebok) used this technology, and the shoe was named Air Uptempo Ultramaitc.

5. Tuned air

The adjustable air cushion has a hemispherical frame structure visible on the surface of the air cushion, which is used to adjust the balance of human body movement at any time. It's basically hard to see now.

6. SHOX

Elastic cushioning columns made of special materials have the functions of shock absorption and buffering at the same time. There are many criticisms. It is relatively hard. If you are not heavy enough (>70KG), it is difficult to feel the presence of SHOX. And because SHOX has a different form compared to other technologies, it is relatively high.
