Not all socks are created equal. Wool socks are especially known for their technical prowess since they wick sweat away from your feet, regulate temperature, and resist odor — an especially important job in the dark, dank abyss that is your moist shoe.
And, spoiler alert: wool doesn’t mean those socks are only meant for cold weather. Thanks to a variety of weaves and weights, you can wear wool socks trekking through the desert beneath a high noon sun (although we may question your life choices).
Still, there are literally thousands of wool socks out there so it’s tough to decide which is the best for you. We spend countless hours hiking, skiing, running and biking outside every year, so we brought a bunch of socks along for the ride. From slushy trails to desert sandstone and powdery steeps, we put these socks to the test. We bring you our favorites.

Frequently Asked Questions
This will vary from person to person. In general, you won’t want socks that are 100% wool because they’ll be itchy, scratchy, and likely miserable to wear. On the lower end, any socks with less than 30% wool will perform more like synthetic socks. Knowing that, we’d recommend socks with roughly 35-70% wool content.
Just because wool socks resist odors doesn’t mean you can skip the wash cycle (all the time anyway). However, excessive washing will wear them down faster and cut their life cycle short. We recommend washing your socks after two or three days of day-long use.
Of course, this will look different for everyone. If you go on a week-long backpacking trip, chuck them in the wash to get all of the grit out. If you’re day hiking for an hour at lunchtime, you can probably go a bit longer.
When it’s time to throw those suckers in the wash, flip them inside out. Use warm or cold water and keep your machine on a gentle cycle with a mild soap. Once they’re done, lay flat to dry so they retain their shape. Some wool socks can be tossed in the dryer, but wool socks are prone to shrinking (especially merino), so we prefer air drying.
