Smartwool® Merino running gear is built for heat, sweat, and steady effort on the road and trail
Over muddy switchbacks and under redwood canopies. Wherever the trail leads, our Merino running clothes and socks are happy to follow. They’re designed to handle long hours of active wear with features like no-chafe flatlock seams and odor-resistant Merino wool liners. Because when you’re comfortable, you can focus on what really matters—like putting some distance between you and the work week.
Our active collection is designed for sweat-inducing activities. With gender-specific, body-mapped mesh zones, Merino + poly blends, and reflective elements for visibility in low-light conditions, these performance pieces will help support your longest hauls.
Our running sock collection is 20 years, thousands of prototypes, and millions of miles in the making. Our athletes and product testers put our Merino wool running socks to the test all over the world—helping us continue to push the limits of our designs.
There’s a running sock for every style—from our cold weather targeted cushion crew socks to our zero cushion low ankle socks. All feature our 4 Degree™ elite fit system, activity-specific mesh zones, and premium Merino Wool.
We make incredible layers and socks for all of your running needs. But did you know we also make Merino wool accessories, perfect for keeping you comfortable from head to toe? Our accessories are made from breathable, temperature regulating, and super-soft Merino. From gloves to lightweight beanies and neck gaiters, we have the gear to keep pace with you.
