“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.

Heavyweight, so no abrasions or

"Heavyweight, so no abrasions or blisters at all. The run true to size, but also fit tightly, which for me, reduces fatigue on longer rucks. They don't stink afterwards and I dont need to wash them after every use."
