The Carhartt All-Terrain Crew Sock has a graduated compression top to ensure legs and feet stay energized throughout the most active day. Mesh cooling panels plus instep channels promote air flow and a braced arch adds stability and holds the sock in place. A resilient wool/acrylic blend transports moisture, naturally combats odor and retains its shape and bounce wash after wash. Reinforced for durability, this sock delivers ultimate all-terrain performance.
