Darn Tough logoDarn Tough socks are guaranteed for life and made in the USA. The best socks for hiking, running, casual wear, and more, our merino wool socks are the best-fitting, most durable socks you'll own, or we'll replace them. We are family owned. For close to 40 years we’ve been knitting socks here in the Green Mountains of Vermont. We are three generations strong and know how to make socks. Crafting the world’s most comfortable, durable, and best fitting socks is an ardent skill passed down from father to son. This commitment, this passion, it’s in the blood. Our unconditional lifetime guarantee is simple. If our socks are not the most comfortable, durable and best fitting socks you have ever owned, return them for another pair. No strings. No conditions. Socks guaranteed for life. If you can wear out our socks we will replace them free of charge.
