How to claim your warranty
Please read the following carefully - there are no strings, we promise! We just want you to have the smoothest experience possible
You’ve already taken the first step towards replacing your socks and allowing us to restore your trust in Darn Tough, for the next step, please follow these instructions:
Mail the pair of socks you’d like to warranty - we need BOTH socks from the pair (single socks will not be processed), along with a completed warranty form or, if you don't have access to a printer, a piece of paper showing your full name, shoe size, where you purchased the socks and how long you've had them along with the reason for your claim (comfort, durability or fit) and return mailing address, to:
Interex Industries Ltd.
Darn Tough Warranty
114 West 8th Avenue
You are responsible for the cost of shipping the socks to us and although we suggest mail, just to keep the costs down, we are not responsible for lost socks and you may wish to consider getting tracking.
Please complete / send 1 form per 1 pair of socks only if you are sending the socks in separate envelopes or sending a mix of men's, women's and kid's styles. No need to send multiple forms if you are sending e.g. ladies socks only and in one package.
TIP: Mail your clean, washed, socks as FLAT as possible – even in multiple envelopes if more than 1 pair – as this will significantly reduce your mailing costs! You can use an ordinary letter sized envelope - mailing your socks by letter mail and flat, rather than parcel post, will keep costs down considerably.
The final step, once we receive the socks and form, is for us to inspect the socks and record any wear areas (this helps us make better socks!) then mail out a replacement pair to you as soon as possible!
Please note that although we do our best to send an exact match, it is sometimes necessary to make a substitution as the style may no longer be in production or not currently in stock, if this is the case, we will replace it with a comparable style (height / cushion / weight / size; NOT colour or the exact same replacement if discontinued or not in stock) in accordance with the warranty policy.
We try our best to send as 'like' as possible but if you are unhappy with what you receive, please note that it is not grounds for an exchange.
Please allow 4-6 weeks for processing and shipping. Occasionally, there may be a longer delay than expected, due to availability of stock. Please note that we do our best to send you replacements as soon as possible and we thank you for your patience.
We hope that you continue to enjoy your Darn Tough socks for many years to come and continue to purchase them from our authorized retailers - we thank-you for supporting our brand.

What does your warranty cover?
Basically anything and everything. If they are not the most comfortable, durable, best fitting socks you have ever owned return the pair to us for another pair. Things that are not covered—disappeared in the laundry, the dog ate them, too close to camp fire, theft by friend or foe, or 'I lost one!' - we only warranty pairs
Can you send warranty replacements before I send in my worn out socks?
It is our policy that we first receive the socks to be replaced so we can examine them. This allows us to ensure that we’re addressing any issues that the worn sock might illustrate.
Does your guarantee include losing 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, he/she has voided our warranty. Dyes are chemicals that can adversely affect the materials we use to make our socks and resizing damages their structural integrity.
