They were a great choice for our leisurely activities as well like hiking around our neighborhood. They also are a great choice or if you tend to have sweaty feet.
Merino Wool is an excellent fabric that naturally wicks and we recommend these socks for extreme activities as well as daily activities in the cold. Darn Tough also makes excellent socks for other sports such as skiing and trail running, but their hiking socks are their most popular and versatile because they perform well for outdoor activities like hiking as well as daily use.
We recommend the version of these socks that come with a full cushion on the bottom. This feature can kept our feet comfortable and prevented irritation in a variety of winter shoes and boots. They also offer a little more protection to keep your feet and skin comfortable in harsher winter climates.

#2 - - Premium Choice

Heat Holders market themselves as the warmest thermal socks, and for good reason. These thermal socks are the antidote to frozen toes and are excellent at keeping feet extremely cozy and comfortable during colder weather.
Coziest Winter Option
According to Heat Holders, they have a Thermal Overall Grade rating of 2.34 (and describe other socks as tending to fall much lower). This means that they will definitely keep your toes warm and retain heat well.
If you’re looking for a sock to keep you dry while sweating, you might want to look elsewhere. We did notice that that kept our feet warm and dry in the extreme cold, but did not offer protection if your feet get wet. For activities where you might be sweating, we recommend one of our other top picks. For example, the Darn Tough Hiker Boot Full Cushion Sock in Women’s and Men’s or the Danish Endurance Merino Wool Cushioned Hiking Socks in Women’s and Men’s.
These are an Amazon bestseller and have an Amazon rating of 4.6/5. Customers rave about the comfort, fit, and warmth of these socks all winter long.

#4 - - The Winter Performance Sock

We love these cushioned hiking socks by Danish Endurance are made of premium merino wool to control moisture and retain heat while also being breathable. These socks feature ventilation mesh lanes that help wick away sweat while maintaining warmth.
They are ideal for hiking and outdoor uses such as trekking, walking, or camping, but they can also be used for everyday wear. One tester took them on a winter camping trip, and they were excellent at performing throughout, and his feet stayed dry the entire time. These are another excellent pair of merino wool socks that can be used with hiking boots, running shoes, or streetwear shoes and feel comfortable in any scenario.
Great for winter performance
According to Danish Endurance, these socks are thermal socks for extreme conditions as well. They are recommended by Rasmus Kragh, who in May 2019 became the first Dane to climb Mount Everest without the use of supplemental oxygen. During his training and different expeditions, Kragh tested these socks for their ability to perform in tough conditions.
Pros:
- These socks are a great value for a good pair of active and outdoor thermal socks, coming in around $30 for a pack of 3 pairs.

These socks can also enhance recovery due to a graduated compression and precise anatomical fit. While they maintain stretch, they also have compressive qualities.

Buying Guide
Here are a few thinks to keep in mind when choosing a pair of thermal socks.
Intended Use of Thermal Socks
Thermal socks can be used throughout the winter for everything from ski sports like downhill skiing, backcountry skiing, cross-country skiing, hiking, sledding, and snowshoeing.
If you’re looking for socks that feel warm and cozy on your feet indoors or during daily activities in the winter, we recommend a pair of socks that have a brushed interior for comfort or made of a heavy bulk yarn. A soft and comfortable fabric is important for a warm pair of thermal socks for this type of activity. One of our top picks is the Heat Holders in Women’s and Men’s for extreme warmth and comfort. These are a great pair of socks for everyday use and keeping feet comfortable and warm.
If you will be participating in activities in the outdoors where your feet might get wet or sweaty, then the warmest thermal socks are actually a blend of wool socks and lightweight fabrics. These socks are more lightweight and have a performance design to make sure that any sweat or moisture is wicked away and that heat is maintained around your foot.
When you are sweating or exposing your feet to the elements, whether that’s hunting, skiing, hiking, or camping, warmth often means staying dry and sweat-free. If a sock is cozy when dry, but wet and damp when cold, then this won’t be a good choice for the warmest pair of thermal socks.
Materials Used
Merino wool is an excellent material for thermal socks and some of the best hiking socks are made of this fabric. Be sure to check out our guide on the best hiking socks of the year as well for some of our tips on this. As a result, merino wool are thermal socks for extreme activities as well as for people looking to have warm feet all winter.
Some other common materials are blends of nylon, polyester, lycra, acrylic, or merino sheep wool. When you’re shopping for your first pair of thermal socks, we recommend reading the list of materials used to make the socks. A good pair will usually have a blend of these types of materials. The percentage of wool in the sock can often dictate what type of activity that sock will be used for.
Cost
Cost is an important factor in our review process and our buying guide. Some performance materials to wick away sweat and keep skin dry can be very costly, so we wanted to choose socks that excelled at doing their job, but also did not break the bank.
We selected thermal socks that were affordable and also well-made and durable. You’ll be pleased to find that these socks will last you for many winters to come, at are at a price point that you can buy more than one pair.
Pro Tip
Before taking your new pair of socks out on a long winter activity, we recommend trying them out first for wear and fit in your home. You can also take them out on a short activity, but have another pair of socks handy in case they don’t work for you.
Like any piece of clothing or footwear, it’s important to choose the right fit for you.
