FAQ: Warranty Program

What does your warranty cover?

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.

How do I file a warranty claim?

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.

I’m on the trail thru hiking and need to warranty my socks. What do I do?

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.

My socks have holes; how do I get warranty replacements?

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.

How long does it take to receive credit after I send my socks back?

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.

I sent my warranty claim in but haven't received my new socks credit yet - how do I check the status?

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.

My warranty credit code is not working! What do I do?

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.
    1. If you are prompted to enter a 6-digit code, please simply close that box.
    2. 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.
  3. Enter your warranty credit code in the "Darn Tough Warranty code" box, not the "Gift card or discount code" box.

Can you send warranty replacement socks before I send in my worn-out socks?

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.

Does your warranty include replacing lost socks? Would you sell me just one sock?

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.

Does the warranty still apply if I dye my socks a different color or if I cut down my socks to make a smaller size?

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.

Can I submit multiple pairs on a single warranty claim?

Yes, please submit all pairs on a single warranty claim. There is an option in blue to "add additional pairs."

Do I need to register my socks in order to file a warranty claim in the future?

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.

International Warranty

How do I file a warranty claim outside the US?

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.

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.

I live in a country where Darn Tough does not have an International Distributor, does that mean I can’t warranty my socks?

You can still receive replacement socks, but you will have to cover the cost of all shipping. For warranty claims in countries without a distribution/warranty partner, we ask that you fill out our international warranty form, then ship the socks and form to our US location using the most cost-effective service. Once we have processed your warranty, a member of our support team will email you to help facilitate your replacement.

I live in a different country than where I originally bought these Darn Tough socks. With whom should I file my warranty claim?

You have the option to file for warranty in either country. Keep in mind that customers are responsible for shipping costs in both directions if claiming from outside a distributor’s region, so you may want to use the distributor in the country you are currently located in.

I am filing an international warranty claim. Will I receive the same sock style back that I sent in?

We do our best to provide the same sock or match the socks as closely as possible. We do have to make substitutions if the sock style you are warrantying is out of stock or no longer in production. In that case, we will replace the socks with a comparable style (same height, cushion, weight, size, and activity category) in accordance with our warranty policy. If you are unhappy with what you receive, we apologize, but please note that it is not grounds for an exchange.

Can I choose a different style or color for replacement when filing an international warranty claim?

We cannot guarantee that a particular sock color or style requests can be accommodated. Some International Distributors do not carry the entire Darn Tough line, so warranty replacements are limited to the styles currently offered in that region.

What if I need a different size? Can I request a different size as part of an international warranty claim?

Yes, no problem! Please have a look inside the front cuff of each sock to see what size you currently have. If you need a smaller/bigger replacement, please indicate what size you would like it changed to on the International Warranty Claim form. Otherwise, we will replace your socks with the same size as received.
