There’s straight-ahead speed, and then there’s VAPOR 1XR speed – the kind of speed that can close the distance in any direction. With a winning fit and feel, you’ll get more go. And the more go you have, the better you play. Every detail, every technology is designed to keep your foot locked in place so your last stride is as fast as your first. From the LOCK-FIT PRO facing and liner to the slow-molding FLEX-LOCK PRO tongue, the 1X will fit like an extension of your foot. So, go. And leave the competition in a cloud of dust.
