Description

Hi. My name is Sal. I’m two weeks old. I love hiking. And I enjoy long trips to/from daycare. In my free time, I like rolling around in the mud. I don’t have teeth, so I won’t bite. But I will keep your kiddo’s feet warm, comfortable, and blister-free. And since I’m Guaranteed for Life, you’ll only have to buy me once. Let’s be friends?

Perfect for
Trail and hike
Micro Crew.
Blister-free fit
Performance knit.
Guaranteed for Life
Reinforced, lifetime-backed.
Features
  • Merino wool blend. Fine Merino wool manages temperature, wicks moisture and resists odor; nylon and Lycra Spandex add durability and stretch. Blend: 47% Merino Wool, 50% Nylon, 3% Lycra Spandex.
  • True Seamless™ Toe. Every toe seam is closed for an ultra-smooth, undetectable feel with no bulk against the foot.
  • Performance fit. A fine-gauge knit with strategic elasticity locks the sock in place — no slipping, no bunching, run after run.
  • Targeted cushioning. Terry-loop cushioning is knit in where you need it to add comfort, warmth and durability underfoot.
  • Guaranteed for Life. Still knit in Northfield, Vermont, USA and backed by Darn Tough's unconditional lifetime guarantee.

Questions, answered

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
How do I pick a sock size?

Darn Tough socks are sized off your shoe size — check the Darn Tough sock chart on this page. This style is offered in SM, MD, LG.

Will Merino wool make my feet itchy?

No. Darn Tough uses fine-gauge Merino wool, which is soft against the skin, naturally temperature-regulating and odor-resistant.

How do I wash them?

Machine wash cold on a gentle cycle with socks inside-out. Do not bleach, tumble dry low or hang dry, and do not dry-clean. Skip fabric softener, which flattens the cushion.

What is the guarantee?

Every pair is Unconditionally Guaranteed for Life. If they are not the most comfortable, best-fitting, most durable socks you have owned, return them for another pair.

Where are they made?

Darn Tough knits every sock at their mills in Northfield, Vermont, USA.
