Long miles and rough terrain don't stand a chance against a running shoe engineered to conquer the challenges of any trail, any altitude and any distance. Double layers of Helion™ superfoam and CloudTec® architecture quadruple the cushioning under every stride, with closed-channel construction and welded overlays keeping stones and trail debris at bay. The breathable sock and mesh shell keep the upper ventilated and moving, while an innovative FlipRelease™ clip loosens the lacing with the flip of a switch to relieve pressure on swelling and soreness as the miles progress or your run is over.
