FOOTSHAPE™ TOE BOX
Allows the toes to relax and spread out naturally and the big toe to remain in a straight position for more stability and a powerful toe-off to maximize running performance.
ZERO DROP™ PLATFORM
Places your heel and forefoot the same distance from the ground to promote low-impact technique, naturally align body posture and strengthen lower leg muscles weakened from running on elevated heels.
GAITER TRAP
This innovative hook-and-loop tab conveniently secures your trail running gaiters to the shoe without having to strap them below the outsole. This prevents annoying debris from building up beneath the shoe.
DURATREAD™
Durable outsole rubber made to last long and offer great grip on both tame and technical terrain.
STONEGUARD
Sandwiched between the A-Bound and EVA midsoles, StoneGuard offers flexible protection from the rugged terrain by deflecting rocks into the midsole for a smooth, stable ride.
TRAILCLAW™
Conquer the gnarly terrain with our TrailClaw outsole technology. Our trail shoes feature canted lugs positioned beneath the metatarsals to provide traction where your foot needs it most. Each lug is strategically placed to ensure fast uphill climbs, stable descents and superior traction across muddy trails.
