2. Air Force 1
Year Introduced: 1982
The first Nike basketball sneaker to feature the then new Air cushioning system, 1982's Bruce Kilgore designed Air Force 1 was a shining beacon of functionality. During the design process, Nike designers played a game of basketball with scissors on the sideline, and every few minutes they had to cut a piece off of the shoe to see what was essential and what wasn't. If the shoe became unplayable, the player dropped out. Practical experiments like this helped in the development of one of the most beloved sneakers of all time, often imitated but never duplicated.
