More info

    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.


    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.


    Women’s feet are anatomically different than men’s feet. Women have a narrower heel and mid foot, higher instep, longer arch and unique metatarsal spacing. The Fit4Her technology means we customize every women’s shoe to the unique shape of the female foot .


    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.
