In this guide
Most hiking socks are sold on wool content and cushion maps. Darn Tough sells style 1466 on a promise: if these are not the longest lasting socks you have ever owned, send them back for another pair. Altitude Sports, one of the authorized Canadian dealers the brand lists, sells the men's pair for $36.99; the maker's US store asks US$26.00.
Coverage that broad deserves a careful reading, because a guarantee is a process before it is a benefit. In Canada the claim does not go to Vermont. It goes to a warehouse in Vancouver, it needs a printed form for each pair, and the payout is a mailed pair that may not match the one you sent.
Our verdict
A $36.99 merino hiking sock worth buying on its knit and fibre blend. The guarantee is real and lasts for life, but in Canada it costs a stamp, a printed form per pair and a wait of roughly two months.
- A good fit for
- Someone who hikes enough to wear socks out, and doesn't mind mailing worn pairs to Vancouver and waiting about two months for a comparable replacement.
- We would skip it if
- You need a replacement quickly, want a refund or the same colour back, or dislike printing a claim form for every single pair.
Reasons to consider it
- The published blend is 61% merino, 36% nylon, 3% Lycra, so durability comes from the nylon content rather than from wool alone
- Darn Tough Canada lists Altitude Sports as an authorized online dealer, and Altitude ships free over $74 and takes returns within 30 days
- The maker's own guarantee page promises another pair with no receipt needed, only the pair in question
The compromises
- You pay postage on the worn pair, and Darn Tough Canada is not responsible for socks lost in the mail
- The replacement is a comparable style in height, weight and size, so the colour may differ, and a colour you dislike is not grounds for an exchange
- There are no refunds, no replacement sent ahead of your worn pair, and Canadian claims are quoted at 6 to 10 weeks
What we have not verified: Wear life per pair is unmeasured, and claim time and postage vary by mailing method. The Canadian warranty page quotes both 6 to 8 and 8 to 10 weeks, and the exclusion for seconds and irregulars appears only on the US guarantee page, so Canadian treatment is unconfirmed.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Hiker Micro Crew Midweight Sock · 1466
The blend and the cushion placement are what you use every hike; the guarantee is a backstop you will only touch after a pair fails.
Before you buy: Check Altitude's sizing chart, which lists M, L and XL, and note that two pairs at $36.99 come to $73.98, just under the $74 free-shipping line.
Price checked October 17, 2026. Retailer prices can change.The blend explains the durability claim
Altitude lists style 1466 at 61% merino wool, 36% nylon and 3% Lycra spandex. Over a third of the sock is nylon, and that is where abrasion resistance lives; merino handles moisture and temperature, but it is not the fibre that survives a season of boot friction.
A high merino percentage is not automatically better. Anyone who has retired socks with holes in exactly two places should weigh the nylon share as heavily as the wool share. These are published percentages, not a measurement of abrasion. The maker's US store prices the same sock at US$26.00; the Canadian price is a separate figure and not a conversion of that one.
Micro crew is a height, and it commits you
Altitude describes micro crew height as peeking just above the top of a standard hiking boot, with mid-level cushion density under the foot and True Seamless construction. Darn Tough's own page calls the sock midweight and pairs it with hiking shoes, hiking boots and backpacking boots.
Height is the decision people get wrong. A sock that ends below the boot collar lets the collar work directly against skin, which is where hot spots start, while someone in low trail runners may find micro crew taller than they want in summer. Sizing needs a second look too: Altitude lists M, L and XL only, while the maker's US store also sells XS, S and XXL, so a very small or very large foot should check the chart before ordering.
What filing a claim in Canada involves
Darn Tough Canada is distributed by Interex Industries, and the Canadian warranty page sets out its own process. Fill in the online form, one per pair, then print the confirmation email or write your name, return address, shoe size and reason for the claim on a sheet of paper. Mail the freshly washed pair with that sheet to the warranty address in Vancouver, or drop it off there on weekdays. The page says Darn Tough does not contact you when the socks arrive.
The wait is the second cost. The page quotes 8 to 10 weeks in its steps and 6 to 8 weeks in its FAQ, and warns of longer delays when the mill has no stock. A replacement will not be sent before the worn pair arrives, and the page states that it does not offer monetary refunds, wherever the socks were bought.
Postage is the first cost. Darn Tough suggests flat letter mail, saying one pair with its form should not exceed one stamp at $2.09 with Canada Post Regular, and cites $3.43 for larger envelopes. That is untracked mail, and the page says Darn Tough Canada is not responsible for socks lost in transit.
What the Canadian guarantee leaves out
The replacement is comparable, not identical. Darn Tough Canada matches height, cushion or weight, size and category of use, and says colour and pattern are limited because styles go out of production; a colour you dislike is not grounds for an exchange. Naming a colour on the form can lengthen the wait on top of the quoted weeks, and the page says a specific colour may never be available.
The US guarantee page adds that socks bought as seconds or irregulars are not covered, and that Darn Tough removed its earlier conditions, including inadvertent damage, on May 21, 2024. The Canadian page lists no exclusions and says the guarantee comes without strings or conditions, so the seconds rule is worth confirming with Darn Tough Canada before you buy a discounted irregular.
When a cheaper sock is the better answer
Someone who hikes a few weekends a year will not wear out any decent wool sock, and the guarantee is worth nothing to a person who never files. At that frequency the money buys comfort and fit, both of which are personal, and a less expensive sock that fits your foot beats an expensive one that bunches at the arch.
Skip it too if a claim sounds worse than buying a new pair. A claim here is a form, a printed page, a stamp and two months of waiting, with no say over the colour that comes back. Anyone who does file is better off keeping worn pairs in a drawer until there is a batch to post, though each pair still needs its own form.
