Altra’s original trail shoe got some fresh new updates to make this version better than ever! First off, the upper is not only more breathable but more durable and secure, it features a static webbing cinch strap at the midfoot, a sandpaper textured toe cap, and improved drainage holes. The outsole got a complete makeover with decoupled TrailClaw™ and multi-directional, carved lugs for increased traction and reduced weight. And just in case all the new features didn’t already have you stoked, the StoneGuard™ is completely new and now resembles the skeletal structure of a foot for dynamic flexibility and better performance. 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. A-BOUND™ Made of recycled materials, this unique layer sits directly under the foot to reduce the impact of hard surfaces and return energy return into each stride. It’s literally a layer of bouncy ball between the road and your feet! 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. FIT4HER GENDER SPECIFIC DESIGN 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 . 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. MAXTRAC This amazing combination of grip, traction and durability will allow you to tackle more terrain, more often. Featured on the new Lone Peak 3.0 Series.
