New Trail Running technology that brings some serious swift, keeping adventure racers centered and efficient to maintain speed over changeable terrain. Proprietary TrailSpring™ design positions visible tubes bi-sected by support beams in a full-length TPU plate to inhibit overpronation and cushion heel-strike. Trail balanced last with integrated arch bridge stabilizes the heel while freeing the forefoot for easy toe-off. Both quick-cinch Airmesh upper and Air Cushion® sole drain readily and are gaiter-compatible. Vibram® Full Speed II™ sole features heel-centering cutaway design and flex grooves for propulsion at the forefoot.
