This running shoe is seriously light. And it all starts from the bottom up. Our ground breaking UA Spine chassis may look a little big, but we carved out all the bulk to create the sturdiness of a stability shoe with the weightlessness of a distance shoe. The body is built with a die-cut MPZ® technology for just the right amount of protection and lateral support. Topped off with a super-breathable mesh overlay, these shoes don’t just look cool, they make sure you stay cool.
