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 color combinations and reliable, lightweight cushioning.
