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.

Reviews

Not For Rucking Only

"Not only do these socks feel great in my Mackalls, but they have become my all-round favorite socks for everyday living. They fit well in the heel and toe box, have just the right tightness, and keep my feet nice and warm, even when I wear them without shoes around the house. I will definitely stock up on them to get me through the winter."

— Christian F. (5/5)

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."
