Are Darn Tough socks really made in Vermont?

Yes, they really are!

What makes Darn Tough socks so tough?

All of our socks are knit on small needle, fine gauge knitting machines. This approach produces durable, high density stitching without bulk. Less bulk means a better fit. The better the sock fits, the longer it will last. We only use fine gauge, high micron 100% merino wool in the knitting of our wool socks—we do not cheapen the wool by adding nylon or polyester to the blend of the wool. We reinforce the outside and inside of the sock with nylon and lycra for added comfort, durability and fit. Throw in 3 generations of knitting know-how, and you get one darn tough sock!

What is the best way to wash my Darn Tough Socks?

Machine wash warm, tumble or line dry, and do not bleach.

Are men’s and women’s sizing different? Are men’s wider?

Generally, as a foot gets longer it gets wider. To compensate for that increase in width, we knit the socks with a bit more cross stretch, roomier if you will, to compensate for that increase in width.

No-Show: 4" above the heel.

¼ Tops and Shorty: 6.5" above the heel

How does your warranty work?

In a nutshell, if you wear a hole in them, we will replace them free of charge, for life. Our socks are guaranteed to be the most comfortable, durable and best fitting socks you can buy. If for some reason you are dissatisfied with your purchase, visit our Unconditional Lifetime Guarantee and fill out our online warranty form.

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 them to us for another pair. Things that generally are not covered—disappeared in the dryer, the dog ate them, too close to camp fire, theft by friend or foe, etc., etc. However all claims made in good faith will be considered. Please note, socks purchased as seconds or irregulars are not covered by our warranty.

How long is the turnaround on warranty returns?

We strive to process your claims within 3 business days of receiving your socks. During peak season, it may take us a bit longer.

Can you send warranty replacement 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.

How do I get warranty in another country?

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. If you are unable to do so, we’re happy to work with you directly to process your claim. Please keep in mind, however, that in cases such as these we would need you to take responsibility for all international shipping-related costs.

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.

What is the difference between Merino Wool and Coolmax?

Merino wool is a durable, natural fiber that keeps you cool in the summer and warm in the winter. Merino wool wicks moisture away from your skin and it dries very quickly. Merino wool is naturally anti-microbial which means you can wear merino wool socks for days on end without them getting that funky workout smell. Coolmax is a durable man-made fiber that is ideal for warmer temperatures. Coolmax wicks moisture away from your skin and also dries very quickly. Coolmax is an excellent alternative for those may not prefer wool or are allergic to wool fibers.

Are the materials in your socks primarily manufactured in the USA?

All of our socks are manufactured in Northfield, Vermont. Our raw materials are sourced globally. That is not to say we don’t use domestic yarns in the production of our socks, because we do. This past year we used more merino wool, nylon, lycra from the USA than from any other country. As to whether all our raw materials are primarily made in USA, depends on many factors—including availability of raw materials, quality of raw materials, price of those materials and capacity of our domestic suppliers to meet our needs. When we can, our first choice is to buy domestically.

Where can I find Darn Tough socks near me?

What is the thinnest sock you make?

Our Ultra-Lights and Lights are the thinnest, lightest socks we make, and we have them in most of our categories.

What is the thickest, warmest sock you make?

The thickest, warmest socks we have are our Men’s and Women’s Hike/Trek Mountaineering Socks. These are over-the-calf socks and provide extra cushioning for the entire foot and leg. The Mountaineering Sock is 25% thicker than our standard cushion socks.

Why do my socks wear out in the same place?

Everyone’s feet are different, but generally speaking, if a person has pressure point spots, it’s more likely that a sock could wear out there.

Do you make diabetic or compression socks?

We don’t make medical-grade compression socks (anywhere from 20-50 mmHg), however, we do make several "Graduated Light Compression" socks that offer graduated compression from 11-16 mmHg to help speed your recovery from even the most intense activities.

Do I need liners with Darn Tough Vermont socks?

Nope. Long ago people used them to compensate for socks that fit poorly but you won’t find that problem with Darn Tough socks.

Any recommendations to shrink socks?

Our socks are preshrunk. They are a snug fit and should be fitted according to your shoe size. You can find our sizing guides on each sock page.

I just bought a new pair of Darn Toughs and both have an “L” inside the cuff. Did I mistakenly get two left socks?

We don’t make asymmetrical socks. That letter actually stands for the size, in this case large. All of our socks are knit with a size letter or letters inside the cuff.

Where do you guys get your wool?

Part of the Darn Tough formula is that we use only the finest merino wool available. With standards so high, we work with select partners to obtain premium wool from North America, Europe and Oceania.

Is the wool you use to make your socks sourced from farms that treat their sheep ethically and humanely?

Our partners do not harm their sheep in the shearing process in any way and do not practice mulesing. It’s a natural, sustainable process.

Do you have brand ambassadors?

We do! However, the application process is closed as this time. Please check back in the future.
