The Altra Superior 2. 0 Men's Trail Running Shoe handles casual hikes as well as sprints to the summit. The Zero Drop platform places your heel and forefoot at the same distance for a natural stride, and the A Bound midsole includes EVA foam for the right amount of lightweight cushion and energy rebound with a low profile and not a lot of bulk. InnerFlex grooves provide flexibility in the midsole for better grip with every step, and Altra added a Contour footbed for extra cushioning. There's also a removable StoneGuard insole that provides lightweight protection from sharp rocks when you're boulder hopping or surfing your way down loose scree fields.The Superior 2. 0 also features Altra's TrailClaw sole, which models sticky rubber after your foot's bones and tendons to give natural flex and targeted support in key areas. The famous FootShape toe box lets your toes spread out naturally to ensure stability on rugged terrain. Up top, Altra equipped the Superior 2. 0 with a quick drying and durable Air Mesh upper to ventilate and keep your foot cool and finished the Superior off with its Gaiter Trap, which lets you securely attach gaiters to the shoe without having to wrap them under your sole.
