    ▪︎ Our merino wool blend naturally wicks sweat — keeping your feet dry and blister-free whether you’re running a 5K or a 50K.

    ▪︎ You know you’re wearing a great sock when you forget it’s there. That’s why we use the softest merino wool for lasting, itch-free comfort.

    ▪︎ On the trail or off the trail, no one wants stinky feet. Our naturally odor-resistant wool blend fights unwanted odors.

    ▪︎ When you want to run fast and light, you shouldn’t sacrifice durability — our reinforced heel and toe ensure these socks will hold up for the long haul.

    ▪︎ We love a little variety in our miles — cool mornings, warm evenings— and we built a sock to excel through it all. Our temperature-regulating merino wool lets you wear these socks for a range of adventures.

    ▪︎ Our socks are thoroughly trail-tested in the Pacific Northwest.

    ▪︎ American Made from Quality Materials: The perfect blend of 57% Ultra Soft Merino Wool, 37% Nylon, and 6% Spandex.

    ▪︎ Ultralight weight: Our lightest, no-cushion sock — feel free and run far.

    ▪︎ No-Show Profile: Perfect coverage when you want to go ultralight.

    ▪︎ Easy Care: Always wash inside out to prevent pilling. Machine wash and dry warm, do not bleach. Can also be hand washed and line dried on the trail.

    Lifetime Guarantee:
