Alpaca Boot Socks - Heavy Duty

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.

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.

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.
