Nike embarked on a four-year mission with teams of programmers, engineers and designers to create the technology needed to make the knit upper with static properties for structure and durability. Then the precise placement of support, flexibility and breathability-all in one layer-was refined. The result is a featherweight, formfitting and virtually seamless upper., Nike air max origins: Nike’s revolutionary Air-Sole unit made its way into Nike footwear in the late ’70s. In 1987, the Nike Air Max 1 debuted with visible air in its heel, allowing fans more than just the feel of Air-Sole comfort-suddenly they could see it. Since then, next-generation Nike Air Max shoes have become a hit with athletes and collectors by offering striking colour combinations and reliable, lightweight cushioning.
