Why do l buy heatholder sock.

The reason l buy heatholder socks is they keep my legs from my knees down warm. When l was 5 yrs old l had polio and from 1971 to 2005 l had 6 operations on my knees with complete removal and rebuilds on both. In 2006 l was told l was a diabetic due to 30 years of shift work !!! .This why l buy these socks. I am 73 now and will do till l die.

Really warm

The warmest I've had
Thank you

Pretty good warm socks.

I have quite a lot of Heat Holder socks in a variety of styles and, though I am a woman, usually wear the men’s version of these because they are more spacious and can be pulled up higher. Though these boot socks are good, I was a little disappointed to find that the top section of the leg is NOT brushed and fluffy inside so the full warmth of the sock doesn’t extend right up to my knee. I think you can see from what I’ve said that I don’t turn the top of the sock down but make it extend as far up my leg as possible. I have a male friend who does the same with his Heat Holder boot socks and also wants the whole of his lower leg to be warm. I wish Heat Holders made a sock that was 2.3 tog all the way up to the knee.

FAQs About Our Original Socks

How do Heat Holders socks work?

There are no batteries, switches, solar panels or other gimmicks! Heat Holders thermal socks are made using our unique three-stage thermal construction:

1. Heat Holders thermal yarn: Our advanced Japanese-designed thermal yarn provides high-performance insulation with superior softness and moisture-minimising breathability.

2. Heat Holders thermal loops: Our innovative knitting technology produces our PATENTED long-loop cushion pile to hold more warm air close to the skin, boosting the socks' thermal overall grade (TOG) rating.

3. Heat Holders thermal brushing: Our expert brushing process maximises the amount of warm air held within the fabric of the socks for unbeatable warmth and all-day comfort.

Are Heat Holders the warmest thermal socks in the world?

As far as we know and based on all the tests carried out so far, Heat Holders socks are indeed the warmest thermal socks in the world.

What is a TOG rating?

TOG (Thermal Overall Grade) is an independent laboratory-tested standard for insulation. The higher the TOG rating, the better the product is at keeping you warm. You’ll see TOG ratings applied to duvets and babywear, as well as thermal clothing like Heat Holders.

How warm are Heat Holders Original socks?

As far as we know and have ever tested, all three weights of Heat Holders socks (Original, Lite and Ultra Lite) are the warmest thermal socks in their respective weight/thickness categories.

Our Original socks have a TOG of 2.3, which is 7 x warmer than a basic cotton sock.

We also have our Original Wool socks, with a TOG of 2.7 and our Original Merino Wool socks, with a TOG of 2.9.
