Over 20 years since its initial release, Nike's Shox R4 is back, revamped for women. Once a top-tier performance shoe in 2000, it embodied futuristic design at the turn of the century. The shoe features its signature smooth synthetic upper with ripple effects and perforations, reminiscent of futuristic space suits. The upper has a white leather base with a metallic platinum panel beneath the Swoosh. The shoe sits atop a barely grape Shox sole, complementing the platinum accents throughout.
