Your feet put up with a lot when it's cold outside — they allow you to cram them into oversized boots, trudge outside into the snow, and hoof it around town in 30 below weather. After all that, you might as well do them a solid by getting the best wool socks you can find to keep them warm in the frigid temperatures.

The truth of the matter is that when it’s horrendously cold outside, only wool will do. Unlike cotton — the great villain of wintertime apparel — wool dries super fast. That means when you step off the curb into that giant mud puddle, you won’t spend the rest of the day listening to squishing sounds sloshing around in your shoes. On top of that, wool has the ability to maintain its warm, insulating properties even when it's wet so you won’t feel your toes going numb while you wait for your socks to dry.

If you can find yourself a pair of socks with a temperature-regulating wool such as merino, you'll get the additional benefit of being able to wear them during every season. Merino wool has the magical ability to keep you cool when it's hot, and hot when it's cool, so you can wear those socks in the spring, fall, and winter.

Furthermore, wool has natural anti-bacterial properties (aka it's "odor resistant") which means that if you work up a sweat hiking across town to the supermarket, your feet won’t explode with aroma when you get back home and take your shoes off. Plus, wool is ultra comfy and cozy, making it the perfect material for curling up in front of the fire with a book, or settling in for a well-deserved Netflix binge. If you’ve got the best wool socks, you’ll be snug and happy all winter long.


The Best For Freezing Temperatures

These unbelievably warm wool socks will help your feet stay toasty and warm when you go outside to brave the cold. Featuring a whopping 85% pure wool, the -40 degree Fahrenheit sock is engineered specifically for the most freezing, sub-zero temperatures around. The trade-off is that the high wool content makes it slightly scratchy so you may want to wear a liner underneath; however, if your bottom line is staying warm, this is the sock for you.

According to one reviewer: "I was looking for some seriously warm, heavy wool socks, and these certainly fit the bill. I spend a couple hours every day walking my dog in the Chugach Mtns. outside Anchorage, AK, and not surprisingly it can get cold. My feet are by far my weakest link, and thick wool hiking socks weren't doing the trick. Now my feet stay warm down to -5F (-20C) with 200 gram winter boots.”

The material, made from a wool-cotton-polyester-spandex blend is breathable and airy, leaving you warm and fresh.

According to one reviewer: "First let me say, I am a sock person in the winter time, hardcore. While socks do not touch my feet during the summer months, I have issues with anemia and once the snow begins to fall my poor toes get cold rather quickly. I happened to grab these on a lightning deal and they are FANTASTIC! Soft, warm and the patterns are adorable! These shall be my 'go to' winter socks for years to come.

These merino wool socks from Icebreaker are made from merino wool, nylon, and elastane, so they’re both warm and lightweight. They boast reinforced heels and extra support around the instep and Achilles, which means they’re great for long hikes or days when you walk around a lot. They’re also super breathable, so your feet won’t get sweaty, no matter what the weather is like.

Editor’s note: “These are my favorite socks for hiking, camping, or days when I walk all over the city and log several miles on my feet. I can really feel the difference that the added support zones in these socks provide, and I love that they’re high-performance with a sleek, minimalist look. They can also be worn for a few days on a camping trip without needing to be washed, which is a huge plus.’’ — Carina Finn
