Year Released: 1985
Sometimes game-changing design doesn't catch on immediately. The Nike Sock Racer is an example, produced originally as a lightweight marathon shoe and favored mostly by triathletes (so easy to get on after the bike segment). Joanne Ernst, winner of the 1985 Hawaii Ironman, sported the Sock Racer and was later featured in the brand's early "cross-training" advertisements. With all the barefoot technology being sold to us as new today, it is important to remember this often ignored mid-80s experiment.
