First launched in 2000, the Nike Shox R4 is defined by its futuristic technology that represents the visual extreme of energetic return. This 'White Flash' version—debuted in June 2019—is faithful to the iconic design with a double-lasted synthetic upper and reflective elements. Neon Swooshes render modern style. The Phylon midsole and two-tone Shox columns combine to enhance cushioning while a rubber outsole supplies traction.
