Originally designed as an innovative running shoe, Nike released its Shox R4 back in 2000. Inspired by spacesuits, a silky silver upper is topped with white synthetic leather, which boasts laser perforations across the design. Holding up the heel are four blue compressive columns that deliver astronaut-inspired bounce and forward propulsion, while the Pebax stability plate keeps you grounded. | HQ1988-101, Textile & Synthetic Upper/Synthetic Sole.
