Considered the greatest tennis sneaker of all time by some, the Air Trainer 1 from Nike changed the direction of sneakers forever. It established a new genre, found its way onto athletes of all types and opened up the world of tennis to colorful sneakers and personalities. The Nike Air Trainer 1 is as iconic as it gets and still avoids the abyss of countless colorways that some silhouettes have fallen into. This year, the Air Trainer 1 celebrates its 25th anniversary. While some silhouettes from the same era seem old and tired, the Air Trainer 1's design, done by Tinker Hatfield, is as attractive today as it was when it first released in 1987. Tomorrow, the original Chlorophyll colorway of the Air Trainer 1 releases around the world, so it's only appropriate that we take a look back at the 25 Best Air Trainer 1s of All Time.
