Running Socks

Lightweight running socks that help prevent blisters, wick moisture, and never slip — ideal for all runners, from joggers to marathoners, and everyone in between. 

If you’ve never tried running in wool socks, here’s a hint: Merino Wool makes the best running socks to prevent blisters. They wick sweat, resist odors, and regulate foot temperature. Knit from ultralight Merino, our thin running socks still hold up mile after mile with unrivaled durability.

From Road Running to Trail Running

Choose your sock based on your cushion preference and run style. For example, road runners may prefer no show and no cushion options for low profile running socks with that close-to-the-pavement feel. We combine ultralight Merino fibers, the ultimate performance fabric, with breathable mesh to keep things light and fast.

Trail runners tend to gravitate to micro crew run socks for protection from debris and scrapes. If you’re running long distances, our cushion socks for running feature an ultralight layer of padding for impact protection and rebound.

Ideal for winter running, our lightweight athletic kits also features zoned cushioning and are still thin, but offer a little extra warmth for cold weather runs.

Performance Fit

All our socks are knit with a performance fit to help prevent blisters, slippage, and muscle fatigue. This close fit acts like a second skin and works with your run shoe.

Optimized support around the center of the foot provides arch support. Combine that with the soft, cushy support in our cushion styles, and you've got socks that are ready to crush your goals.
