The Nike Shox Gravity returns in new form with exceptional performance and design features. Nike Shox technology first launched in 2000, and the Shox Gravity has been updated to deliver an unparalleled in-shoe experience with Nike Shox foam for cushioning and shock absorption. Primarily dressed in black, the shoe gets lit up with volt green accents on the innovative lacing and Shox systems. The stand-out feature is the dark blue iridescent heel counter. Underfoot, four circles on the outsole of the Nike Shox Gravity are inspired by rocket engines.
