The revolutionary Nike Air-Sole unit began being used in Nike shoes in 1978. In 1987, the Nike Air Max 1 was introduced with a visible Air-Sole unit in the heel, allowing fans of the model not only to feel but also to see this groundbreaking technology. Two years later, the Nike Air Max 95 made its appearance with a visible Air-Sole unit in the forefoot, while the Nike Air Max 97 was released with the first full-length unit. The shoe became a favorite model among runners, as expected from its wavy design lines. More than two decades later, it continues to make waves.
