Slip on the most comfortable, durable, best fitting socks you now own.
When we say our socks are durable, it’s about more than wearing through – it means they will remain comfortable, with a performance fit, day after day. Our warranty data helps us improve, and we knit a better sock.
The unconditional guarantee ensures we maintain the standards we set. Does it drive us to be better? Absolutely.
We get it, the idea of “unconditionally guaranteed” could be interpreted differently, but we guarantee our work, and our socks. Hike to the Moon, and we will cover that kind of wear, but if you leave them there, we don’t want to assume responsibility for that.
We don’t need a receipt, we don’t need a reason – although we do like to see them, and if you want to share a story, we are always curious. In the meantime, these are the most common questions we can answer:
We can only speak to the sock itself, not dogs or other means of devastation brought on by not wearing the socks on your feet. They are not trailer tie downs.
Merino Wool is naturally flame resistant, but fire can be avoided. They will survive a brief encounter with flame, but they won't save you pain from a fire walk. Nor will we cover that.
We only warranty pairs, not singles. There's still a good chance they are hiding in the pant leg or sleeve. Regardless, loss is not something we can prevent on our end.
★★★★★Stephen F.I literally only own Darn Tough socks. I kinda want to see how good their customer service is, but their durability prevents me from it.
★★★★★Tanya P.I recently had a fit issue a certain sock style. I contacted Darn Tough, and they stood behind their guarantee (it's not just words). I could not have been more pleasantly surprised by their excellent customer service. The new socks fit perfectly. I love them!
★★★★★James S.Darn Tough socks have lasted longer than any sock I have ever owned. I did recently have a pair develop some thin spots and holes in high wear areas and Darn Tough replaced them no questions asked.
★★★★★Mary M.I love Darn Tough Socks. The online replacement is easy. I am amazed by the Lifetime Guarantee and will continue to buy them and replace them.
★★★★★Danny B.Best socks ever and the lifetime guarantee is real. I sent a 5 year old pair back because some stitching came loose, I got a credit for another pair. BOOM just like that.
★★★★★Tara S.Can't wait to take advantage of your lifetime guarantee, but so far our socks just won't wear out. I think we have a pair that is at least 10 years old and worn often. They just keep going strong.
