AIR SOCK RACER ULTRA FLYKNIT PREMIUM REVOLUTIONARY RIDE The Sock Racer raised more than a few eyebrows when it first launched in 1986. With its stretchy, laceless upper, it looked more like a sock than a running shoe. Its unique blend of flexibility and full-length cushioning caught on, though, giving runners a comfortable, natural-feeling ride and creating a new paradigm for future footwear. It returns in premium fashion, featuring a full Flyknit upper, lightweight Ultra sole and radiant rainbow fade. In good pre-owned condition. Size- 9 Color- Rainbow
