In the world of Nike Shox, a metallic silver pair of Shox R4 is up there with the best of them.

Over 20 years since it first released into the market, Nike's Shox R4 is back on the scene and looking wild as ever. It's hard to consider that this was one of Nike's top-tier performance shoes in 2000, but this is what the future was looking like at the turn of the century.

Although Shox technology didn't really take the running world by storm, the out-of-this-world look of the cushioning system cemented the shoes into the memory of a whole generation. Nike revisits that nostalgia by returning to the original Shox model and giving it a faithful reproduction – just in wild new colourways.
