1. Please read the Warranty FAQs below - most claims qualify for a replacement pair but there are a couple of rare exceptions. Also, please read the details below thoroughly.

​

2.  Prepare your claim:

• Complete the warranty form. You can download a form from this page but If you don't have access to a printer, send a piece of paper showing your full name, mailing/return address, shoe size & preferred sock size, where you purchased the socks and how long you've had them along with the reason for your claim (comfort, durability or fit)

• Please complete & send 1 form per 1 pair of socks unless you are sending multiples of the exact same sock.(ie. exact same - STYLE, COLOUR, HEIGHT, SIZE etc)

• If you need a different size, please indicate it on the Warranty form in the section 'Preferred socks size', otherwise we will replace them with the same size as received. The sock size is woven inside the front cuff of each sock (you will see a capital letter - S, M, L, XL etc.). Please see the size chart below or click HERE.

• Prepare your socks for mailing. They MUST be freshly washed.

• Make them as flat as possible so they will fit in a letter sized envelope (8.5" x 11") to keep the shipping cost down (1 small envelope with 1 pair of socks along with the form shouldn't be more than the cost of 1 stamp/$2.09 when using Canada Post Regular (no tracking). This is a suggestion only, it is at a discretion of Canada Post and please check  with Canada Post for rates.

• You can find a few examples of lettermail we receive on a daily basis sent to us via Canada Post HERE ($2.09 for the smaller sized envelope/each and $3.43 for bigger envelopes/each). Although we suggest letter mail, just to keep the costs down for you, please note that we are not responsible for lost socks and you may wish to consider getting tracking.

• Note - you may need more than one envelope but that is usually cheaper than mailing them together by parcel post. We need BOTH socks from the pair (a complete pair). Single socks will not be processed. Please double check that they are Darn Tough - we cannot warranty any other brands for you! ;)

3.  ​Mail to our warehouse.

4.  The final step, once we receive the socks & form, is for us to inspect the socks and record any wear areas (this helps us make better socks!)

• We DO NOT contact / inform our customers once we receive the socks. 

•  Once checked, we record your information into our system, then mail out a comparable replacement to you as soon as possible.

• We understand that you want your awesome new socks as soon as possible but please allow 8-10 weeks for processing and shipping before contacting us to follow up.

• Occasionally, there may be a longer delay due to unavailability of stock (we are limited by the Darn Tough mill availability). We will send you a comparable sock as soon as we can but sometimes there are no comparable styles available and we must wait for the mill to knit some more! 

• Sometimes, if you sent multiple pairs we are unable to send all pairs back at the same time due to stock availability. Rather than have you wait, we send back what we can. The remaining pairs will remain on file until we can fulfill your warranty claim. 

• We ship replacement pairs in separate envelopes (up to 4 pairs) so please note that they might be delivered on different days!

• Although we do our best to match the socks as CLOSE as possible, we usually have to make a substitution as the style / colour may no longer be in production or not currently in stock. If this is the case, we will replace the socks with a comparable style (height, cushion/weight, size & usage category) 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. 

​

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.
