Who's up for a hike? You are, and these socks are! You'll get the best wear out of these socks while hiking, trekking, or trail running in any season with the comfort of Merino Wool. The WRIGHTSOCK™ Patented anti-blister system with dual-layered socks. The inner layer wicks away moisture to keep your feet dry whilst controlling the temperature of your feet. Merino wool outer keeps feet warm in cool weather and cool on those hot days. The dual layer absorbs the friction that normally transfers to the skin causing blisters.
