Merino Wool Socks

Merino Wool socks are the best socks for every activity. Moisture-wicking, anti-odor, anti-blister, cool in hot weather, warm in cold – Merino Wool is where it’s at. Add in our Unconditional Lifetime Guarantee and the fact Darn Tough socks are made in the USA (in Northfield, VT, to be specific), and you know you’ve found quality.

For comfortable feet that are always the right temperature, wool is your best bet. We knit a range of cushion, height, and weight sock options so you can find the right wool sock for every activity, including thru hiking, backcountry skiing, bike racing, and… couch lounging. Our ultra-lightweight socks keep things cool and airy in running shoes while our heavyweight socks lock in warmth on a glacier or in your house.
