Nike Air Max is a line of shoes produced by Nike, Inc., with the first model released in 1987. Air Max shoes are identified by their midsoles incorporating flexible urethane pouches filled with pressurized gas, visible from the exterior of the shoe and intended to provide cushioning to the underfoot. Air Max was conceptualized by Tinker Hatfield, who initially worked for Nike designing stores. Overview M. Frank Rudy, an aeronautical engineer, first brought the idea of an air-cushioned sole to Nike in 1977. In 1979, he patented a design using polyurethane sacs filled with pressurized inert gas, and Nike has been using some version of this design ever since. As the name indicates, all Air Max shoes feature one or more translucent pouches of pressurized gas embedded in the midsole and visible from the outside of the shoe. Referred to as "Air units" or "airbags," their stated purpose is to provide superior cushioning to traditional foam while also reducing weight. The effectiveness of the technology for this purpose is disputed; nevertheless, the shoes enjoy consistent popularity, especially among sneaker enthusiasts and collectors. The size, design, and number of air units varies within the product line; the "retro" Air Max 1 simply includes one small unit under the heel, while in the contemporary Air VaporMax, effectively the entire midsole is composed of air units with no conventional foam present.

The extremely inflated prices of the shoes led to a rash of muggings in the normally-peaceful country wherein Air Max wearers were attacked and their shoes were stolen. Even used shoes were in demand, and fakes also became a problem. Models Air Max 1 Released in 1987 as simply the Air Max, the Air Max 1 was the first shoe ever to employ Max Air technology. It was marketed for running, which would continue to be the case for new Air Max designs until 2018's Air Max 270. Its upper was composed of nylon and synthetic felt, with a leather version being released in 1988. The Air Max 1 continues to enjoy significant popularity with sneaker enthusiasts, with Nike releasing "retro" models employing both
