Features
- Merino 10 wool blend. Fine-gauge 200-needle merino naturally regulates temperature and resists odor — warm when it's cold, cool when it's hot.
- Anatomical design. Right/left-specific fit with a wider toe box — each sock is knit for your actual foot.
- Targeted arch compression. A secure, custom-like fit that locks the sock in place and supports long miles.
- Seamless toe. The Perfect Toe® closure cuts friction where blisters start.
- No-slip cuff. Gentle cuff compression keeps the sock up without sliding or squeezing.
- Made in the USA. Designed and produced in the USA.
Size & Fit
Materials
- Fabric: 49% nylon, 24% merino wool, 23% Tencel, 4% spandex — a 200-needle merino wool blend.
- Care: machine wash cold or warm on the gentle cycle with a mild soap, avoiding bleach and fabric softeners. Tumble dry low. Turn inside out before washing; for best results, hang or lay flat to dry.
About the brand
Feetures began around a kitchen table in small-town North Carolina, where a family of lifelong sock makers set out to prove that a performance sock could actually make you move better. Still family-owned today, they obsess over every knit and fiber — anatomical right-and-left specific design, targeted compression for a custom-like fit, a seamless toe that shuts down blisters, and iWick fibers that keep feet cool and dry. At Mountain Sports, we love Feetures because they sweat the small details that make big miles feel easy — socks built to outlast the season and keep you moving.
