NIKE SHOX R4 SPMaking its audacious debut in 2000, the Shox R4 shattered the mold of traditional sneakers with its futuristic look. It combines a silky smooth synthetic upper with fluid ripples and laser perforations, which take style cues from space suits and other astronaut gear. Four compressive columns lift the heel while offering both a stable structure and bona fide bounce. Product Code : IQ0636 300
