Best-in-class wool socks built for time and distance We put our feet through hell, so our socks must meet the highest standards—no blisters, no friction where the sock meets the shoe. The Merino Wool Challenge Sock - Crew was built to tackle anything from rucking miles across the rainforest to sandbag workouts in your driveway, these socks won’t wear thin or lose shape. They’ll keep your feet dry and, even after days of use, they don’t stink. Ultimately, they work well with any shoe but were designed to counter friction from the heel cup over time and distance when wearing boots. They’re unconditionally backed by our Scars Lifetime Guarantee and proudly made in the USA.

I ordered the XL based on the sizing chart (men's 12-14.5), but these were incredibly tight. They felt like a compression sock rather than a comfortable crew sock. My toes were cramped, and they were difficult to pull on. Had to return them because the fit was just not right.
I wear these inside my work boots for 10+ hours a day, and they've made a huge difference. My feet stay dry, and I've had zero issues with rubbing on my heels. The Charcoal color also hides dirt well. Will definitely be getting more pairs.
These socks are exactly what I needed for my hiking boots. The targeted cushioning prevents any rubbing or hot spots, even on longer trails. My feet stay completely dry and blister-free, which is a huge improvement over my old cotton socks.
The Merino wool fabric feels great and keeps my feet dry during longer walks. However, these run a bit small, especially around the ankle, making them somewhat uncomfortable after a few hours of wear. I got the Small and usually wear a women's 6, but wish I'd sized up.
These are truly the best rucking socks I've ever owned. The Merino wool keeps my feet cool and dry no matter how many miles I put in, even in humid conditions. They prevent any friction from the heel cup of my heavy boots, which used to be a constant issue for me. The cushioning is just right – supportive without feeling bulky. Definitely buying more pairs in Coyote and Black.
