Unconditionally Guaranteed for Life

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 darntaugh.com in the last 90 days, you probably want to start a return or exchange instead.

We Knit a Longer Lasting Sock

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.

Our Guarantee Means Everything

The unconditional guarantee ensures we maintain the standards we set. Does it drive us to be better? Absolutely.

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.

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!

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.

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.

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.

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.

On May 21, 2024, aiming to better serve our customers, we removed previously listed warranty conditions, including inadvertent damage. Please note that socks purchased as seconds or irregulars are not covered by our warranty.

FAQ: Lifetime Warranty Program

What does your warranty cover?

We will replace your socks free of charge:

  • If they are not 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.
  • If your socks are inadvertently damaged.

As long as we can tell that they were once a pair of Darn Tough socks, our warranty will apply. All claims made in good faith will be considered.

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 Ground Advantage). 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.

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.

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 reach out to our support team. To check the status, use the same email used to file your claim.

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

Please ensure you are using the same email at checkout that was used to file the claim originally. If the emails don't match, your credit will not apply.

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 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. 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.

Can I warranty my socks no matter how damaged they are?

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.

Can I submit multiple pairs on a single warranty claim?

Yes, please submit all socks 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 are the socks. We knit our name on all our socks, so we know where they came from, no receipts or proof of purchase required.
