If you remember our instructions, you won’t have any problems when you search for thermal socks in your local sports shops and supermarkets.

You also may ask a shop assistant to help you to choose the best thermal socks, however, they are sometimes busy, not willing to help or trying to make you pay as much money as you can. We think that you can study some information regarding thermal socks and make a decision on your own. These are the features which you should take into account:

  • Materials

Top 6 The Best Thermal Socks for Winter [2020-2021] - Review

The material which your socks are made of is the most important feature. The right choice of material will make your winter activities joyful and comfortable, while the wrong choice will prevent you from proper walking or skiing, or any other activity. In the list below you can see the good and the bad points of each of them.

  • Merino wool

This is the warmest material for thermal socks. If your socks are made of merino wool, it will guarantee that your feet won’t get cold at any temperature. Another good point is that this wool is antibacterial and naturally wicking, which makes them smell well enough even after kilometers of hiking.

However, the wool itself is expensive and can be itchy in its pure condition, so often it is combined with some synthetic material to avoid itchiness.

  • Synthetic materials

Top 6 The Best Thermal Socks for Winter [2020-2021] - Review

Synthetic materials like spandex and nylon are good for blending with merino wool since they add elasticity and support while also provide a cushion. But it’s good to remember that synthetic materials themselves are not so warm as wool and don’t have its waterproof quality, that’s why they are usually combined with wool in order to produce the best thermal socks.

If you see any pair of thermal socks made of totally synthetic materials, don’t forget that they cannot save enough warmth so they are not suitable for being outdoors for a long time.

  • Cotton

Although you may find cotton thermal socks in some local shops and online, we don’t recommend buying them since cotton is a good material for summer socks, however, since it is truly breathable and holds water, cotton socks are horrible for winter activities.

  • Weight and thickness

The weight and thickness of a thermal sock are another important feature to think about. When the sock is heavy and thick, it will certainly be warm enough, however, it can make any physical activity difficult and it will make much discomfort during fitting them into your boots or shoes.

So we recommend you to concern the footwear under which you will put your thermal socks when you choose a pair of socks to buy. The best thermal socks for physical activities will be thin enough and mid-weight as well as made of mostly merino wool to be super-warm.

But if you need socks for any slow activities or for sitting or standing, you may choose thicker and warmer socks.

  • Activity type

This particular feature corresponds with both materials and thickness. For instance, if you are planning to snowboard a lot, you should keep in mind that your feet will sweat, so you need a material that is moisture-wicking as well as flexible in motion.

Or, if you will just be watching a football game or hunting slowly, you need more warmth and less flexibility from your socks and you don’t have to think a lot about their waterproof.

  • Durability and cushioning

Most thermal socks are sold to provide some cushion, but they will offer more comfort if they have some added cushion on the footbed or heel. This will be perfectly suitable if you are going to use them in a house that has hard flooring, such as hardwood or ceramics.

In addition to this, some thermal socks brands try to reinforce toes and/or heels to make socks more durable since these areas face the most pressure during walking. It would be nice particularly when you buy an expensive pair of socks, so you know that they won’t wear out too quickly. Some thermal socks companies even provide a lifetime guarantee as they produce very high-quality socks.

  • Color and design

That’s right – we should pay attention to such things since even nobody sees them you should feel comfortable and confident that every item of your clothes is stylish. Moreover, if you use thermal socks somewhere in a house, it’s truly essential to feel good when looking down on your feet. You may smile or even laugh at it – but nice clothes make your good mood!

Top 6 The Best Thermal Socks for Winter [2020-2021] - Review


To sum up, it’s important to think carefully about what pair you would like to buy. You should think of the material, their weight and thickness, correspond it with the winter activity you’re going to perform as well as choose some pretty design.

If you don’t want to do your own research, you can choose from our top-6 presented above. Otherwise, we hope that all the provided information will be enough for you to make the right choice.
