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.

“You will never pass Special Forces training if you don’t learn how to take care of your feet.”

This was 2004 and my interest in socks, and footcare, became an obsession right then and there.

Padding Where You Actually Need It

We got sick of wearing out other socks so we added more padding along the heel and ball of the foot. The heel padding is extended up to the achilles to actually give you cushion where you need it when wearing boots like MACV-1.

Fits Right, Even After All the Miles and All the Days

Extended arch support and a natural fit through the ankle and calf makes for a comfortable sock that’s not too tight and doesn’t slip over time and distance. These socks maintain their shape wear after wear.

Wear Often, Wash Sparingly

Merino wool naturally resists bacteria and fights stink. Wear as often as you want without having to wash ‘em after each use. Saving you both water, and time.

Holding up well

"Since receiving a few pairs of challenge socks, I’ve purposely decided to wear the same pair for a few weeks straight on my Rucks, 5 miles 3x’s a week,30lb plate, no holes, hot spots, no smell and my wife is nice enough to smell them for me to make sure my analysis is correct 👍 great socks and they pair well with your shoe and boot offerings."
