Sock Features

  • 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.
