If you’re often exposed to the cold, it’s important to keep your feet warm to distribute heat around your body. The reason your hands and feet get cold first is that your body prioritises heat for your vital organs.

We’ve scoured the internet to find the best thermal socks in the UK that are also heat holders to keep your feet warm and comfortable.

Thermal Socks Reviews

Justay 5 Pairs Ladies Winter (Editor’s Choice)

These are one of the best thermal socks in the UK for women. Designed to retain warmth, these socks are perfect for the winter season. They also boast a comfortable thickness that makes them perfect for footwear.

The socks are made with high-quality thermal contents, including 36% polyester, 35% wool, and 29% cotton. Cotton is a soft fabric that’s warm and comfortable on your skin, making this product just what you need if you often experience cold feet. Thanks to its polyester component, these winter socks are lightweight and durable, ideal for wearing regularly.

Best of all, the Justay thermal socks keep your toes dry all day and feature a breathable toe panel. Therefore, you can even use these as hiking socks. In fact, the socks prevent moisture from building up, which can also be a contributor to cold feet.

On the other hand, this five-pack of socks is only right for wearing with boots, and the height won’t provide much comfort if you’re wearing trainers. They’re also only available in earth-tone colours, which isn’t ideal if you’re searching for more colourful socks.


  • Appropriate hiking socks with elasticated cuffs for comfort
  • Made with a high percentage of cotton
  • Shape-forming feature that provides a comfortable fit
  • Polyester adds excellent durability to make sure they last


  • The socks may only be appropriate for wearing with boots and not with trainers
  • They don’t feature an elastic material, therefore, they may fall down

FALKE Men’s Cosyshoe (Luxury Choice)

If you’re looking for the best thermal socks for extreme luxury, FALKE might have a product for you. These slippers keep your feet warm and comfortable, and they’re perfect for wearing in cold weather. Plus, their slipper design means that they’ll make the perfect pair to use around the house.

This product will ensure you have warm feet for long periods of time, thanks to the materials used. In particular, they contain merino wool, which is a temperature-regulating fabric to make sure that your feet don’t get cold. Furthermore, the combination of polyamide is great for comfort and retaining heat.

Moreover, another reason that these are one of the best thermal socks for extreme cold in the UK is that they feature silicone nubs on the sole for enhanced gripping and to prevent you from slipping over. This makes these thermal socks right for wearing in the bathroom and kitchen or rooms where there could be a potential slip hazard.

Unfortunately, these winter slippers don’t come with a clasp, which could mean that the fastening is slightly loose. And you should follow the included washing instructions to prevent the slippers from shrinking in the wash.


  • Great for wearing in cold weather
  • Slipper design that makes them perfect for wearing indoors without shoes
  • The inner sole is plush and cushioned for comfort
  • With fold-over cuffs, you can reduce the sock’s height to your preferences


  • Might be too thick for boots
  • No clasp, which may provide a looser, less secure fit
  • Could shrink in the wash if you don’t follow the washing instructions included

Caterpillar 6 Pairs Men’s (Best Value)

With this purchase, you receive six pairs of some of the best thermal socks in the UK that are available in blue, black, white, and grey. They come in any size you could need, making them suitable for all.

These are one of the best thermal socks for wearing on a construction site because they have a reinforced toe and heel that prevents blisters and bubbles caused by wearing work boots. This design protects your feet from injuries while providing excellent durability that’s great for everyday use.

In addition, they come with a thermal adjustment that’s designed to keep your feet at the correct temperature. This keeps your feet comfortably warm when it’s winter and not too stuffy during warmer weather. In fact, these socks prevent a build-up of sweat, so you can work conveniently without extra moisture on your feet.

However, these may not be considered to be thermal socks for extreme temperatures and you may still experience some chill on your feet if you don’t use them with boots.


  • They’re great if you suffer from blisters and sores on your feet
  • Durable and don’t tend to receive holes after a few uses
  • Keep your feet at the perfect temperature, so you’re not too hot or cold

These thermal socks are made from 30% merino wool, 33% acrylic, 36% nylon, and 1% elastane. Using a high percentage of merino wool, these are one of the warmest socks you can buy right now. Plus, they’re ideal for wearing in winter because they act as a good insulator.

In addition, this pair of socks has moisture-wicking properties that retain the heat within the sock while remaining breathable. This makes them a great option if you’re often going out in the cold. You can walk for long periods of time without building a pool of sweat inside.

They’re one of the best socks for extreme cold weather because they boast an array of thermal materials. This includes 35% wool, 29% cotton, and 36% polyester. The wool retains heat, keeping your feet warm in winter.

In addition, they provide plenty of ventilation to prevent a build-up of sweat while offering a good amount of comfort.

However, these socks might not be good for hiking, because they don’t feature an elastic cuff. This can make them prone to falling down when moving for long periods of time.

Furthermore, the socks also have plenty of elasticity that provides extra comfort and means that you can move around freely without feeling restricted.

The high content of acrylic offers ample comfort and softness, so you can wear the socks for long periods of time with shoes or even indoors without footwear. In addition, the wool contributes to keeping the cold weather and moisture out.

What to Look for When Buying Winter Socks

Buying socks isn’t as easy as you may think and there are several factors you should know about before making your decision.


Here are the top three fabrics to consider when buying thermal socks.

Merino Wool

Merino is easy to care for because it’s both stain and odour-resistant, so you don’t have to wash the material as often as synthetic socks. In fact, airing out merino socks will keep them fresh and dry for the next day.

Furthermore, the material can absorb around 30% of its weight in moisture. Therefore, you can take merino thermal socks with you when you hike, and they’ll still keep your feet warm and dry. They also boast sweat-wicking properties.

Most important, merino wool keeps you warm, as it regulates your body’s temperature. This works through the natural crimp within the fabric’s fibre that traps body heat in pockets for optimum warmth. Best of all, this material feels soft against your skin.


Another fabric to invest in is elastane. This material increases thermal resistance to retain heat in your feet, making it a great option for thermal socks. Combined with spandex or lycra, it adds a little stretch to the socks to provide a comfortable fit. You’ll typically only need around two to five percent of the sock’s content for these benefits.

You’ll find that numerous thermal socks contain polyester. This fabric is durable and much stronger than cotton and even wool. Aside from its longevity, polyester socks also retain their shape, making them more comfortable to wear over long periods of time.

Furthermore, a high-quality blend of polyester socks will feel soft against your skin, so you’ll want to wear them even during vigorous exercise.

And polyester is lightweight, too, which is advantageous for supporting your feet. This feature means that you can walk around the office all day without your feel feeling stuffy or hot. Better still, the material won’t bunch up like some other materials, so the socks will stay in place all day long.

Sock Thickness

Thick socks keep in more heat and also provide ample cushioning, which is ideal if you’re a heavy runner or suffer from aches or foot sores. For winter, you may want to consider thicker socks than compared to the rest of the year. But for long hikes, you may want to take a few pairs of various thicknesses along with you.

Sock Height

Finally, the sock height is also critical to your comfort. Ankle socks are best for running because they keep your feet warm and they complement trainers. If you’re wearing boots, you may want to consider a taller pair to keep your shoes from digging into your skin.
