Debuting in 2000, the Nike Shox R4 revolutionized performance footwear forever with their proprietary shock-absorbing polyurethane columns in the heel. These columns took sixteen years to develop at the Nike labs, all with the goal of turning the impact of running into an advantageous energy return for the runner. The Nike Shox R4 quickly transcended the world of running though, and became streetwear icons thanks to their futuristic athletic look. Amidst the wave of Y2K nostalgia, Nike brought back the Shox R4 through re-releases and collabs, making the Nike Shox R4 more relevant ever.
