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.
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.
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 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. 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 check the status of your claim here. To check the status, you must use the same email used to file your claim.
If you need assistance, please reach out to our support team.
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.
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 where you are currently located. You can find the international warranty contact information for our active distributors by country here, as well as more FAQs specifically addressing international questions.
If there is no warranty service available in your location, we're happy to work with you directly to process your claim. Please keep in mind, however, that in these cases you are responsible for returning your socks to Vermont, USA.

Every time my socks wear out, they've happily accepted them and sent me vouchers for a new pair. The only downside is that you have to pay for shipping your old socks back to them. But love that they take back old socks, in any conditions, even unmatching pairs!
