More grip and reduced weight makes the Altra Superior 2.0™ sneaker even more coveted than its predecessor. Constructed of durable, breathable trail mesh with synthetic overlays, this men's lightweight trail-running shoe features a FootShape™ toe box for natural splay atop the Zero Drop™ platform. InnerFlex™ midsole technology delivers an added degree of responsiveness to adapt to rapidly changing terrain. Canted lugs in the TrailClaw™ sticky rubber outsole offer superior grip over the most challenging terrain; a removable StoneGuard™ plate protects from stone bruising.
