Warm boots and shoes are a necessity in cold temperatures, but you also need something to keep your feet warm.

Otherwise, you’ll kick them off as soon as you get back inside and your feet can get really cold really fast!

Although there are plenty of winter-specific socks out there claiming to be the best rated, it’s hard to know the truth because there are so many brands, designs, and materials to consider.

To eliminate the guess work, I made sure to test out a wide variety of socks.

I wore them for a long period of time in some of the coldest temperatures, just so I could be assured that I found the warmest socks in 2020.

The Darn Tough Men's Over The Calf Sock is so reasonably priced that I ordered a few pairs for my exercise wardrobe and my day-to-day use. Have only worn them for a short time, but so far they seem to be a good basic sock for hikers, as well as for many other uses.

Frequently Asked Questions (FAQ)

What are the warmest socks on the market?

While many socks claim to be the warmest, you should be wary of marketing hype. If you’re trying to stay warm on a cold winter day, you want a super warm pair of thermal socks that will keep your foot warm all day. The best warm winter socks should do this without making your feet sweat or keeping them too hot.

So we tested over 20 different warm socks in 2019. We tried all of the different types of winter socks: boot socks, mid-calf, knee high socks, and socks made from 100% wool. After testing each of these winter socks in a variety of conditions, we outlined the best quality 100% wool socks which keep your feet warm all day long without causing any sweating.

What type of socks keep feet warmest?

There is a large range of socks at the top of the market that make big claims to keep feet warm. Some, like Thorlo socks, have been around for decades and have stood the test of time, while others like Uniqlo and SmartWool boast state-of-the-art technology for maximizing warmth. There are even socks that claim to keep feet cooler than regular socks, like Darn Tough’s “Ice” line. In fact, if you’re not interested in warming your feet but rather getting an ice-like chill, take a look at the Top 5 Coldest Socks in 2020 below!

After trying out 41 different sock brands from over 20 different brands, we tested our finalists in a variety of temperatures and conditions like while working indoors, running, lifting, and walking.

What are the warmest socks for cold weather?

If you are looking for the warmest socks for cold weather, wool socks are always a good idea since they naturally provide great insulation. No matter what shape or size the wool fiber is, it retains air that traps heat inside the socks.

In our last 60-day trial, we tested 6 wool options out of 24 pairs in our 5K+ member community. Here are the results!

Plantwo Wool Socks (4.6 /5)

Meet the second most popular wool socks we’ve tested so far! They are a warm pair of socks that do a great job of keeping the feet warm and dry. They have a good amount of fiber at 50% and they have a nice cozy texture. The material is heavy enough to be durable, but not overly thick. The result is lightweight yet warm socks perfect for cold weather walks.

Conclusion

We believe in doing our due diligence before ever recommending anything to our readers. It took a long time to create our testing method and test the socks, but we hope there was a lot learned along the way. Not all socks will fit the needs of every person, but hopefully this guide will help you find the perfect pair for your warm winter feet.
