Heat Holders, the warmest thermal sock in the a statement that we don't make lightly, but one we have every confidence in, and a title we believe we have earned.

Heat Holders are thermal socks which possess a 2.34 tog rating and have been produced using a unique three-stage knitting process. This means that our customers can be certain that wearing Heat Holders will keep their feet warm like no other sock has before. Heat Holders' reputation has grown tremendously, with over 10 million pairs sold worldwide so far, but our success wasn't achieved overnight. The creation of such an innovative and high-quality product took years of brain-storming, design and experimentation to get to where we are today.

How It Started...

Back in 2006 the term 'thermal' was fast becoming associated with 'budget'. The thermal sock market was flooded by products which were cheap to make and cheap to buy. Most available socks offered very poor insulation and were therefore utterly redundant in their sole task of keeping people's feet warm. Appalled that customers weren't getting what they were paying for, we decided to bring the market what it was missing - a high-quality, affordable thermal sock that actually worked.

Two years later... 

Two years were dedicated to creating this sock, as we retooled and completely redesigned our machinery to deliver what we set out to achieve. Once built, our new machines were able to produce an extra-long looped pile which locks in warm air close to the skin; the fundamental key to thermal insulation. Yarn mixes were routinely tested and discarded until the final blend was discovered – a warm and cosy feel that was incredibly soft to the touch and super – comfortable to wear. Finally we developed our intense brushing process, the method a closely guarded secret to this day, which maximises the number of small air pockets and in turn maximises your total warmth, comfort and overall thermal protection. In December 2014 Heat Holders were granted a UK patent verifying that only Heat Holders are constructed using the unique extra – long loop pile distinguishing them from all of their competitors.

and not only that!..

We also achieved the scientifically accredited 2.34 tog rating that we are so proud of. When you compare that to the 0.89 tog rating of an ordinary thermal sock, it truly highlights how warm Heat Holders really are and why we call them...



In 2008 we introduced Heat Holders and by the end of 2009 we had revolutionised the thermal sock market. From our original product the Heat Holders line has grown to include long leg, stripe, slipper, ski, twist and Wellington boot socks, as well as hats, gloves, tights, leggings, thermal underwear and more - all created with the same underlying belief that warmth comes first. Today Heat Holders are not just a sock but a concept. Our promise and our commitment to you is to serve up a supreme thermal brand you can both recognise and trust.
