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.

Stephen F.

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!

Tanya P.

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.

James S.

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.

Mary M.

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.

Danny B.

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.

FAQ: Lifetime Warranty Program

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. 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.

For customers within the US, fill out our online claim form. Ship your socks and completed claim form back to us using the cheapest method available (which for most customers is USPS first class mail). We will process the socks and form and email you a credit code for the full replacement value of your claim to use on our website.

We understand that following our standard warranty process may not be possible if you’re in the backcountry for an extended time period. If you need to warranty socks mid thru-hike, you can use our Store Locator to find a Darn Tough retail partner near your location who accepts in-store warranty exchanges. Simply change the top filter on the Store Locator from “All Stores” to “Authorized Warranty Center” to view participating retailers.

If there’s no locations near you or you are unable to go in store to complete a warranty exchange, you can also contact our customer service team with the subject line “Thru Hiker Warranty,” and they will be happy to assist you.

For customers within the US, fill out our online claim form. Ship your socks and completed claim form back to us using the cheapest method available (which for most customers is USPS first class mail). We will process the socks and form and email you a credit code for the full replacement value of your claim to use on our website. You can learn more about this process on our warranty page.

We strive to process your claims within 7-10 business days of receiving your socks. During peak season, it may take us a bit longer.

Our current turn around time for processing warranty claims is up to two weeks. If you shipped your socks back to us more than three weeks ago, please first check your spam or junk folder. The email with your replacement credit is sent from support@darntough.com with the subject line "Warranty Claim Processed."

If it has been more than 3 weeks since you submitted your claim, and there is nothing in your junk mail, please reach out to our support team.

Here are a few troubleshooting steps to follow if you are having trouble applying your warranty credit to your order on our website.

  1. Ensure the email you're using at checkout matches the email you used to file your warranty claim.
  2. Select the regular "Checkout" button instead of using any of the express checkout options.
  3. If you are prompted to enter a 6-digit code, please simply close that box.
  4. If you find yourself in the ShopPay checkout, click "Check out as guest" to be routed to the regular checkout where you can enter your warranty credit.
  5. Enter your warranty credit code in the "Darn Tough Warranty code" box, not the "Gift card or discount code" box.

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.

Our guarantee applies to socks that have not met expectations relating to comfort, durability, and fit. But if one of your socks was stolen by a falcon, you can send us back the remaining single sock for half credit.

We don’t sell single socks.

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.

If you want to extend the life of your socks by darning them, we will still cover them under our warranty when you do eventually need to replace them.

As long as there's enough of your sock remaining that you can send it back to us and we can tell it was once a Darn Tough sock, we'll cover it. Even if there are more holes than sock left.

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.
