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.

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.

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.

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.
