Heat Holders

These Mens Ultra Lite Cardinal Plain Thermal Socks in Charcoal are specially designed to fit comfortably inside tighter-fitting and formal shoes. With an amazing 1.0 TOG rating, these men's thermal socks are three times warmer than a basic cotton sock, so you get more of our famous thermal protection with less of the bulk.

Formal and tighter-fitting shoes can often feel cold to wear. Not only do they offer less insulation than casual shoes, but most of the socks that will fit inside them provide little or no thermal protection.

Heat Holders Ultra Lite are different! 

Size: UK 6-11, EUR 39-45, US 7-12

Length: Crew length socks

Fibre Composition: 89% Acrylic, 10% Nylon, 1% Elastane

Machine Washable at 40°C. Heat Holders can be tumble dried but are happiest when line dried.

Brilliant Socks!

Love these. I've used the thicker version of these socks for years, but these are perfect because they are thin enough to fit inside slippers and socks, but still much warmer than ordinary socks. I used to get really cold ankles until I got these. Highly recommend them and have now bought some for my husband.

FAQs About Our Ultra Lite 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 Ultra Lite 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 Ultra Lite socks have a TOG of 1.0 TOG, which is 3 x warmer than a basic cotton sock.
