Slip on the most comfortable, durable, best fitting socks you now own.
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.
The unconditional guarantee ensures we maintain the standards we set. Does it drive us to be better? Absolutely.
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.
We will replace your socks free of charge:

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.
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 socks 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 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.
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 for our active distributors by country here, as well as more FAQs specifically addressing international questions.
If you live in an area without active distribution of Darn Tough socks, we’re happy to work with you to process your claim and still replace your socks for free. However, in such cases, you are responsible for all shipping and international costs, including but not limited to the cost of shipping us your old pair, us shipping you the new pair, and any local taxes, import duties, customs clearance fees, etc.
