Why HeatHolders Might Be the Warmest Socks in the World

A man wearing HeatHolders—the warmest socks in the world

The right pair of socks could be the difference between sickness and health this winter.

Researchers conducted a study into the effects of cold feet on getting ill. Half the participants had their feet immersed in ice-cold water for 20 minutes. During the next five days, 29% of them developed cold symptoms, compared to only 9% of those who avoided cold feet.

Not only that, of all those who caught a cold, those from the chilled group reported worse symptoms.

The researchers suggest that low body temperature causes constriction of the blood vessels in the upper airway. This reduces the supply of white blood cells and inhibits the ability of the immune system to fight viruses.1

As the temperature drops this winter, warm feet will be important to our health, comfort and happiness.

HeatHolders socks offer unbeatable protection from the cold. Are they the warmest socks in the world? Probably.

Let’s look at the evidence and consider why warm feet are so important to our well-being.

The Warmest Socks in the World

After being disappointed with other thermal socks on the market, we spent two years creating the warmest socks we could.

We invested in new machines that were able to produce socks with an extra-long looped pile, which keeps warm air close to the skin.

We also tested different mixes of yarn until the perfect blend was discovered—one that’s warm, soft and comfortable.

Finally, we developed an internal brushing process that increases the amount of warm air the socks trap.

The result? A uniquely warm and comfortable sock that achieved a scientifically accredited warmth rating of 2.34 tog. That’s seven times warmer than a basic cotton sock (0.33 tog) and over two and a half times warmer than a basic thermal sock (0.89 tog).

We also received a UK patent for our extra-long looped pile construction, so you won’t find this technology in any other brand.

Since inventing the original HeatHolders sock, we’ve launched the Lite and Ultra Lite ranges. The Lite socks fit comfortably in ordinary shoes and have an outstanding tog rating of 1.6.

The Ultra Lite socks are ideal for tight-fitting shoes. They use a short loop pile to achieve a fantastic tog rating of 1.04, making them three times warmer than a basic cotton sock.

The HeatHolders range means you enjoy warm, comfortable feet in any shoes at home, at work and outdoors.

Tog Ratings Explained

Tog ratings are a British system used to describe the warmth of a product. The higher the number is, the greater the insulation the product offers.

Tog ratings for clothing are assured by British standard 4745, so you can be confident that it’s an accurate measure of warmth. HeatHolders socks achieve a market leading tog rating that’s greater than high-quality walking socks from other well-known brands.

Why Warm Feet Are Important

Your feet, along with your hands, have a huge impact on your body temperature. They have a large surface area and specialised blood vessels that increase blood flow and shed heat when the body is hot. That’s why sticking your feet out from underneath the duvet feels great in summer.

However, it also means your feet get cold quickly. When cold, the blood vessels in your feet constrict and blood flow reduces. Add in the fact that your feet have relatively little hair and muscle, which generates heat, and your feet can quickly get cold.2

When your feet are warm, you’re happier, more comfortable and more mobile. You can walk, run and jump more easily, so you enjoy being outdoors in cold weather.

To keep your feet warm, you need to trap as much warm air next to the skin as possible. HeatHolders does this better than any other brand.

Are HeatHolders socks the warmest socks in the world? We think so, and the evidence agrees:

  • Two years of research and testing
