While a sturdy pair of snow boots is essential to get through winter, if you find your feet are still getting cold, it might be time to invest in some thick wool socks. The fabric's built-in insulation keeps your feet much warmer than their cotton, polyester, or bamboo counterparts, making them the perfect complement to your winter footwear whether you're skiing or shoveling snow.

We love the Darn Tough Micro Crew Midweight Wool Sock for women because it's designed to balance coziness with temperature-regulation. For men, we recommend the Darn Tough Micro Crew Cushioned Sock thanks to its nonslip fit and antimicrobial properties.

These are the 10 best pairs of wool socks that shoppers say will keep your feet warm all winter long.

Tips for Buying Wool Socks

Consider the materials

If you're afraid wool socks will be rough and scratchy on your feet, don't be. Most companies use merino wool in their designs. Merino is not only softer than regular wool but it's also known for its moisture-absorbing capabilities and odor-resistant properties — so it will keep your feet dry and smell-free even as you work up a sweat. Plus, merino wool is often mixed with other materials like nylon and elastane to give the socks extra stretch and comfort.

Think about the intended use

All wool socks will keep your feet nice and toasty, but some are designed with special features that make them perfect for outdoor activities. If you're looking for a pair to wear while skiing, you should opt for a thinner, seamless option, so your heavy ski boots won't cut off your circulation. Meanwhile, hikers might want to opt for a pair that features mesh vents for added breathability. And if you're just looking to keep your feet warm in cold climates while commuting or sightseeing, consider an extra-thick option that has built-in cushioning.
