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.
But cold feet can lead to poor blood circulation, which can contribute to health implications. Therefore, a good pair of socks could make a world of difference. Fortunately, there are a plethora of thermal socks on the market to keep your feet warm this winter.
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
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

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.

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 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.
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.
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.
