Product DNAThis running shoe is deceptively light. And it all starts from the bottom up. Our ground breaking UA Spine chassis may look hefty, but we carved out all the bulk to create the sturdiness of a stability shoe with the weightlessness of a distance shoe. See that body design? It’s our MPZ® technology, die-cut 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.
