The air sign on Nike shoes indicates that the product is equipped with Nike's homemade shock absorption technology, that is, an air cushion made of special gas and air pressure. Generally, Nike shoes marked with air logo are equipped with air sole air cushion, which is an early air cushion of Nike and is generally comfortable, but it is absolutely more than enough to meet the daily leisure and comfort needs. Such air cushions are generally common in the Air Force series.

Ike Air professional air cushion contains a special gas, which is injected into tough synthetic rubber by high pressure. The key to the success of Nike Air technology is that the volume of special polymer gas in Nike Air professional air cushion is larger than the tiny gap of synthetic rubber layer, so the gas in the air cushion will not be lost. Nike Air gas molecules absorb external shock and impact pressure, and then quickly recover to the original state, ready to absorb the next impact. At the same time, it will not wear with the life cycle of shoes.
