Injinji's Trail Midweight Crew sock is designed to provide ultimate foot protection and comfort on long runs and challenging hikes over rugged terrain. The toesocks minimize friction between toes, allowing your feet to move naturally in narrow spaces and cushioning them against the impact of the terrain. The crew length prevents debris from entering and the arch band provides support. Special COOLMAX® fibers and mesh venting ensure breathability and keep feet dry and cool, whilst nylon fibers add durability.
