It’s important to consider what you will be using the socks for and what type of activity you’ll be doing in the socks.

Darn Tough Boot Cushion Sock Check latest prize

If you’re looking for a thermal sock that is well-made and long-lasting, look no further than Darn Tough’s Full Cushion Sock for Hikers. Made in Vermont, Darn Tough socks excel at keeping your feet comfortable even in extreme winter conditions.

Best for active lifestyle

If you’re looking for a pair of socks for active winter activities such as nordic skiing or hiking, these are an excellent choice for moisture control. 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.


  • Darn Tough socks have a lifetime guarantee, so your purchase is guaranteed for quality.
  • These socks are exceptional at moisture-wicking and keeping your feet dry while sweating.
  • These Merino Wool socks are breathable even in extreme conditions or during extreme activities such as winter sports or snow sports.
  • The cushioned bottom is great for hiking or walking and keeping the bottom of your feet comfortable in winter shoes and boots. They also offer arch protection.


  • These socks can be pricier than other options, so aren’t as affordable.
Heat Holders Thermal Socks Check latest prize

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. They also come in a variety of colors and patterns, so can be a good choice for everyday use or if style and color is an important choice when determining the right pair of thermal socks for you.


  • These are an extremely warm and cozy pair of socks that are great for every day use.
  • Heat Holders thermal socks are make of heavy bulk yarn, which keep feet warm and comfortable.
  • These socks trap heat while also maintaining comfort due to inside of each sock being intensively brushed.
  • Heat Holders socks are affordable and have a great price point, so these socks won’t break the bank.


  • These aren’t the best at moisture wicking, so if you’re looking for a sock to keep your feet dry while sweating, these probably aren’t your best choice. They also aren’t the most lightweight thermal socks on the market.
Carhartt Extremes Heavyweight Sock Check latest prize

These Carhartt socks might be our best pick for an all-around thermal sock choice. With a 4.7-rating on Amazon in 2022, these socks fit the bill for a variety of uses and customers. We loved using them for everything from going to the office to cold winter hikes outside.

Carhartt began as durable workwear clothing brand and has branched into outdoor and active gear. As a result, their pairs of socks offer functional warmth at a great value.

Best socks for a variety of activities

These socks are made of a blend of materials that includes 66% Acrylic, 21% Merino Wool, 12% Nylon, and 1% Spandex. As a result, they have some moisture wicking capabilities with high quality merino wool, as well as a blend of materials that offer everything from antibacterial properties to comfort in low temperatures. They can be used for a variety of purposes and are a great all-around pick for a thermal sock.


  • These socks are popular and affordable with a $10 price point.

  • These socks are simple and stylish and come in a variety of subtle and neutral colors.


  • These are a great pair of all-around socks, but aren’t the best pick if you’re looking for something super specific, such as snow sports or ski socks.
Danish Endurance Merino Wool Cushioned Hiking Socks Check latest prize

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.


  • 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.
  • Danish Endurance thermal socks can be used for extreme conditions such as hiking and training in cold and wintery environments.
  • Made of Merino Wool, these feature thermoregulation by way of the merino wool blend. This means that they keep your feet feeling good in summer activities and also warm in the winter.
  • The cushioned bottoms keep feet comfortable and come with arch support. This can help prevent blisters and hot spots from hiking as well as provide arch support for miles of hiking or traveling outdoors.


  • These are excellent pair of performance socks, but are lightweight and specialize in performance. If you’re looking for something super soft or with a cozier feel to it, try one of our other recommendations for thermal socks.
Icebreaker Women's Ski Plus Medium OTC Socks Check latest prize

These Icebreaker Merino wool socks are our top pick for a longer pair of wool socks that go over the calf.

Great sock for longer coverage

These thermal socks are a great choice for people that want to get sock coverage over the calf for longer winter boots, or can also be used with ski boots.

These over the calf socks are made of 65% Merino Wool, 33% Nylon, and a 2% Elastane blend, which offers breathability and odor resistance along with helping with cold feet.

These socks can also enhance recovery due to a graduated compression and precise anatomical fit. While they maintain stretch, they also have compressive qualities. Some describe that compression socks enhance performance and recovery, and we’ve noticed these socks are a great choice to maintain circulation in the winter as well as enhanced our recovery afterwards.


  • The longer fit of these socks work well for winter boots, including snow boots, ski boots, and longer rain boots.
  • Icebreaker Merino socks have graduated compression and maintain a precise anatomical fit that can help with performance and recovery.
  • Merino wool maintains breathability and naturally wicks while keeping feet fresh in the cold and heat.
  • The longer fit of these pair of socks can maintain extra warmth and coverage over your foot and calf and can protect skin from colder conditions.
