All the benefits of Altra's award-winning minimalist running shoe are back with a hot, new look in the Altra Instinct 2 barefoot-inspired sneaker. This men's athletic shoe boasts a quick-drying air mesh upper with streamlined seaming construction lining to wick moisture and reduce chafing. The distinctive foot-shaped toe box gives toes more room to work properly; the Zero Drop™ platform allows a more natural, efficient foot strike that helps reduce joint impact, shin splints and forefoot pain. A dual-density, cushioned footbed rides atop a cushioned midsole providing essential shock absorption and responsiveness. Built on a male-specific last, the Altra Instinct 2 runner is finished with a blown rubber outsole to provide a natural, all-purpose traction system for a variety of surfaces from road to treadmill to trails.A-Bound™ TechnologyAsymmetric LacingA-WrapBack pull loopBlown rubber outsoleDual-layer, EVA cushioned midsoleFootPod™ OutsoleFoot-Shaped DesignGender Specific Footwear by AltraMesh upperNRS - Natural Ride System™Padded collar and tongueStack height: 25 mmWeight: 9.5 ouncesZero Drop™ FootwearStyle Number: A1333-1View All Altra ProductsCustomer Reviews for Men's Altra Instinct 2
