Year Released: 1987

It would be hard to find a bigger year for Nike — and newly minted sneaker designer Tinker Hatfield — than 1987. The architect (of buildings) became the architect of a category when Nike introduced the Air Trainer, a shoe built for a new discipline called "cross training." Running, weightlifting, basketball — anything an all-around athlete would do. And if that wasn't enough versatility, the shoe was adopted by petulant tennis star John McEnroe as his matchday shoe. As with any Hatfield shoe, the function dictated the form, but the form stood on its own.
