Year Introduced: 1987

The Nike Air Trainer 1 wasn't the exactly the first multi-sport sneaker - pretty much any sneaker designed before 1970 filled that role - but it was one of the first designed expressly to be a multi-sport sneaker. Tinker Hatfield developed a shoe that would be equally at home on the courts or in the gym, and John McEnroe proved its worth by essentially adopting it as his signature shoe. The "chlorophyll" colorway remains a grail to many despite several re-releases.
