Darn Tough

Merino wool socks that stay comfortable, dry, and in one piece, backed by a lifetime guarantee.

Darn Tough is known for merino wool socks built for hiking, running, skiing, work, and everyday wear, in every height from no-show to over-the-calf and a wide range of weights and patterns. Its standout is the unconditional lifetime guarantee: if a pair isn’t the most comfortable, durable, best-fitting sock you own, the brand will replace it. The merino wool naturally manages moisture, regulates temperature, and resists odor, so feet stay dry and comfortable in both warm and cold weather. What sets it apart is the durability and the fit, with cushioning options from ultra-lightweight to heavyweight and men’s, women’s, and kids’ sizing. It’s made for people who spend long days on their feet and want socks that last for years.
