Known for its innovative designs and heritage sport aesthetic, Nike delivers all the best street and sportswear across a range of sweats, tees, pants and classic kicks. Debuting in 2000, the Shox R4 broke convention with its futuristic design, pairing a silky synthetic upper with fluid ripples and laser-perforated detailing inspired by spacesuits and astronaut gear.
