Few things are worse than experiencing numb toes on a cold day due to a poor choice in socks. One incident may be enough to drive you to buy dozens of pairs of wool socks for future winter runs or lazy days spent lounging by the fire.

Sourced from the fleece of an animal — typically from sheep, but also goats, alpacas and camels — wool is the textile fiber that comprises the warm, relatively coarse fabric you know and love. The fiber itself is renowned for its insulating and antibacterial qualities.

Contrary to popular belief, wool is suited for both warmer and colder months. "Wool is a thermoregulating fiber, so it's great for year-round wear," sayss Kristen Pandolph, vice president of product engineering and innovation for socks at Bombas. "Not only does it trap heat against the body when it's cold outside to help keep you warm — the natural crimp of the fiber creates air pockets — but also when it's warm out, it provides a cooling effect by pulling moisture away from your body and letting it evaporate quickly." (

Some wool socks are made with pure wool. For example, "a luxury wool sock would be made from 100 percent Merino wool yarn in the body, or a casual boot/ragg sock may be knit from 100 percent lambswool, which has a larger diameter fiber and can be used for chunkier gauge knits," says Pandolph. (If you're wondering, Merino wool is sourced from Merino sheep, which are known for producing fine wool which lends itself to high-quality fabrics.) Technically, these "all-wool socks" will always still include a percentage of polyester or spandex added for stretch and recovery, according to Pandolph.

Other times, socks are made with a wool blend. "The addition of other fibers can change the handfeel (softness or harshness), performance (pilling rate, moisture-wicking function) and durability of the socks — all of which can have both pros and cons," says Pandolph. "For instance, adding cotton to the wool will reduce the natural stretch of the yarn, or adding nylon to the wool might increase the durability and reduce pilling, but result in a scratchy or stiff fabric that is less breathable." (

All things considered, wool socks deserve their reputation as the ultimate base layer for winter activities, but they also have other use cases. Here, the best wool socks to add to your drawer.
