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 (with Q-form stride alignment for women) drain readily and are gaiter-compatible. Vibram Full Speed II sole features heel-centering cutaway designed and flex grooves for propulsion at the forefoot.
