Description

The Altra Lone Peak 9 is a women's trail running shoe built for legendary adventures. Altra reengineered the upper for durability, with no-sew overlays and a 100% recycled ripstop mesh made for high mileage. A lighter Altra EGO midsole keeps a comfortable connection to the ground, and the improved MaxTrac outsole adds sticky grip. Zero drop and Altra's roomiest toe box give the classic Altra feel, with room for toes to move freely.
