My sons cold feet

My husband has several pairs of your very warm socks, and when my Son in Sydney complained about their cold winter! I had no hesitation in buying him 3 pairs to send to him, he’s thrilled with them👍

Soft and warm

Bought as a present for my partner. He was very pleased with them and said they had a lovely, soft interior and kept his feet warm.

Great value for money

Bought them for partner who has diabetes and his feet are always cold. These socks keeps them warm and them are loose enough to be comfortable.

FAQs About Our Original Slipper Socks

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.

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.

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.

What's different about your slipper socks?

Heat Holders thermal slipper socks and lounge socks, also known as ‘gripper socks’, offer all the warmth and comfort of regular Heat Holders socks plus a non-slip grip on the sole. Heat Holders gripper socks are perfect when you need a little more traction on indoor wood or tiled surfaces, without sacrificing on comfort and warmth.
