Designed by Bruce Kilgore, the Nike Shox R4 made its debut in 2000 - 16 years after Shox technology was originally developed. Expanding its lineup, Nike presents a black and 'Metallic Gold' edition, which features laser perforations and fluid ripples on the astronaut-inspired upper. The bounce comes from underfoot with four 'Metallic Silver' compressive columns at the heels. This stylish sneaker features a textile and synthetic upper with a synthetic sole for durability and comfort. Nike Shox R4 Women's - black, Textile & Synthetic Upper/Synthetic Sole.
