The Men's Altra Lone Peak 9 features a reengineered 100% recycled ripstop mesh upper with no-sew overlays, specifically built to provide high-mileage durability on technical terrain. A revised Altra EGO™ midsole foam is now lighter than previous versions, delivering a comfortable, responsive connection to the ground that keeps you moving efficiently. For superior traction, the updated MaxTrac™ outsole offers sticky underfoot grip to handle loose dirt, rocks, and mud with confidence. Complete with Altra’s signature Balanced Cushioning™ and the roomiest Original FootShape™ fit, these trail runners allow your toes to splay naturally for maximum stability and comfort throughout the day.
