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.

Socks are final sale and not eligible for returns or exchanges.
