Inspired by the rocky and rugged mountains of Utah's Wasatch Range, Altra Lone Peak 2.0 running shoes are designed to help you tackle such rough terrain. Endurance runners specifically will benefit from reliable stability in both uphill and downhill directions. A Stone Guard™ combined with the Trail Claw™ outsole protect your feet from rocks and other debris with cushioning comfort.Upper: Gaiter Trap hook-and-loop tab conveniently secures the trail running gaiters to the shoe without having to strap them below the outsole. Padded tongue and heel collar enhance comfort. Lace-up front offers an adjustable fit. Quick-Dry Trail Mesh provides breathable flexibility.Midsole: Foot Shape allows the toes to relax and spread out naturally and the big toe to remain in a straight position for more stability and powerful toe-off to maximize running performance. Abound sits directly under the foot to reduce the impact of hard surfaces and return energy into each stride. Stone Guard™ offers flexible protection from the rugged terrain by deflecting rocks into the midsole for a smooth, stable ride.Outsole: Trail Claw™ positions canted lugs directly below the foot metatarsals and “claws” near the front of the shoe for incredible traction in uphill and downhill conditions.
