If these aren’t the longest lasting socks you’ve ever owned, you can return them to us for another pair. No receipt needed, just the pair in question.
Our online warranty process is easy ... 6 steps. But if you purchased our socks on DarnTough.com in the last 90 days, you probably want to start a return or exchange instead.
Issue discovered, decision to return socks made.

Clean socks, include your form, send them back.
We will email you a code to use on darntough.com, once we receive and process your pair.
Your new pair of lifetime guaranteed socks will ship for free.
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.
Our socks are guaranteed to be the most comfortable, durable, and best fitting socks you can buy. In a nutshell, if you wear a hole in them, we will replace them free of charge, for life. Things that generally are not covered—disappeared in the dryer, the dog ate them, too close to a campfire, theft by friend or foe, etc., etc. However, all claims made in good faith will be considered.
Please note, socks purchased as seconds or irregulars are not covered by our warranty. For more information about our Unconditional Lifetime Guarantee or to start a warranty claim, visit Our Guarantee page.

It is our policy that we first receive the socks to be replaced before issuing credit for new pairs. If you are in a time pinch, contact our support team, and they have some tricks to speed up delivery of replacement socks.
While it’s pretty darn comprehensive, our guarantee does not cover sock loss, and we don’t sell single socks. Our guarantee applies to socks that have not met expectations relating to comfort, durability, and fit.
No, when a customer alters the sock in any way, through resizing or dyeing, they have voided our warranty. Dyes are chemicals that can adversely affect the materials we use to make our socks, and resizing socks damages their structural integrity.
Yes, please submit all pairs on a single warranty claim. There is an option in blue to "add additional pairs."
No sock registration required. All you need when filing a warranty claim with us is a complete pair of Darn Tough socks. We knit our name on all our socks, so we know where they came from, no receipts or proof of purchase required.
We unconditionally guarantee our socks for life. If they’re not the most comfortable, durable, best fitting socks you’ve ever worn, return them for another pair. In return, we ask that you submit any warranty claims in the country from which they were purchased. You can find the international warranty contact information by country here, as well as more FAQs specifically addressing international questions.
If you are unable to do so, we’re happy to work with you directly to process your claim. Please keep in mind, however, that in cases such as these customers are responsible for all international shipping-related costs.
