While a sturdy pair of snow boots are 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 compliment to your winter footwear. 

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. 

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 for a pair to keep your feet warm in cold climates on your daily commute, consider an extra-thick pair that has built-in cushioning. 

To help you figure out which pair of wool socks is best for your needs, we scoured through thousands of customer reviews to see which ones they love the most. Whether you're looking for a durable men's pair of wool socks to wear while hiking or a breathable women's option, these are the 12 best pairs of wool socks that shoppers say will keep your feet warm all winter long.
