Darntough Due North Women's Snow Socks 2026

Cold feet? The struggle is real. For the never warm, our synthetic Due North ski/ride socks are built for two purposes: warmth and longevity. The hollow, moisture-wicking fibers from our 100% recycled THERMOLITE® ECOMADE materials trap heat and insulate feet with a soft, dry layer that protects you from hot spots, holey socks, and the need for frequent visits to the lodge to thaw out.

• Women's over the calf socks average 16.25 in. from heel to cuff - expect them to cover the leg to just below the knee.
• A performance fit means no slipping, no bunching, no boundaries. Here's to feeling connected and comfortable in your boots run after run.
• Reinforced Achilles cushion reduces heel lift, which helps socks feel better on and last season to season.
• We close every toe seam using our True Seamless™ Toe technology for an ultra smooth, undetectable feel.
• Synthetic THERMOLITE® is a vegan option that is lightweight and insulating so your feet feel good.
• Midweight Thermolite® synthetic socks insulate and protect feet run after run. Vegan friendly.
• The “still” in Still Made in Vermont, USA is personal. We knit all our socks at our VT-based Mills using the highest quality yarns, sourced from around the globe.
• Unconditionally Guaranteed for Life - if these aren’t the longest lasting socks you’ve ever owned, return them for another pair.

Care Instructions: Machine wash in cold water on gentle cycle with socks inside-out. Do not bleach. Tumble dry on low or hang dry. Do not dry clean. You can learn more about how to wash merino wool socks here.
