MILE TWENTY, NO HOT SPOTS

Zone-knit alpaca built for long days under a full pack.

ZONE-KNIT CUSHIONING

ZONE-KNIT CUSHIONING

Thick under the heel and forefoot, thin across the top. Padding where the pack weight lands, breathability everywhere else.

WATER BEADS UP AND ROLLS OFF

The fiber repels water and sweat instead of holding it. Wet feet are what turn friction into blisters.

FLAT TOE SEAM

FLAT TOE SEAM

No ridge across your toes to rub for ten miles. The seam you stop noticing because it isn't there.

SIZING

Between sizes? Size down. Alpaca relaxes slightly with wear, and a sock that shifts inside your shoe is what creates the hot spot you are trying to avoid.

Sizes are US shoe sizes. Our socks are unisex, so the men's and women's ranges overlap inside each size.

GOT QUESTIONS?

Alpaca fiber is naturally hollow — tiny air chambers wick moisture, release heat and trap warmth when you need it. It's softer than sheep's wool, drier than cotton, naturally odor-resistant and lanolin-free, so it's gentle even on sensitive skin.
View material comparison chart
Machine wash cold on the gentle cycle with mild detergent, then air dry. Skip bleach and fabric softener — they break down the natural fiber. They'll keep their shape and softness wash after wash.
Our socks are unisex and sized by US shoe size. Most styles run Medium (Men 6-9 / Women 7-9.5), Large (Men 9.5-12 / Women 10-13) and X-Large (Men 12.5-15). The Hiking and Trail Ankle socks use their own grid: Medium (Men 8-10 / Women 7-10), Large (Men 10.5-13 / Women 10.5-12), X-Large (Men 13.5-15). Between sizes? Size down — alpaca relaxes slightly with wear, and a sock that shifts inside your shoe is what creates hot spots.
View size guide
Our compression line uses graduated 15-20 mmHg support — firmest at the ankle, gentler up the calf. It should feel like a supportive hug, not restrictive. First-timers usually adjust within a day or two.
Every order is covered by our 30-day comfort guarantee. Not in love? Reach out within 30 days for an exchange or a full refund — wrong size swaps are on us.
Start a return
Orders are processed within 1-2 business days and US delivery usually takes 5-9 business days after that. Orders over $50 ship free — and you'll get a tracking link by email as soon as it's on the way.
