Heat Holders

Whether you’re putting in a tough shift, working long hours in cold environments or staying on your feet all day long, these Ladies Original Workforce Thermal Socks in Black won’t let you down.

Our Workforce socks are an evolution of our classic and warmest Original Heat Holders socks, engineered for unbeatable warmth and comfort at work.

To meet the demands of the toughest workplace, we’ve boosted protection and durability in the heel and toe, which usually see most impact and wear. We also use a special fibre blend and knitting structure for these elements, making them more resistant to abrasion (rubbing).

Size: UK 4-8, EUR 37-42, US 5-9

Length: Crew length socks

Additional Features: Reinforced heel and toe

Fibre Composition: 91% Acrylic, 5% Nylon, 3% Polyester, 1% Elastane

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

Buying more of these as I can find nothing warmer, and working outside I appreciate that. However, although the Workforce socks wear better than the regular, I find holes develop around the reinforcing e.g. on the sides, which is really disappointing. FYI with the regular, it's the soles and heels which wore thin.

Warm and comfortable

Working in a warehouse in the winter I need socks that are warm and comfortable. Being heat holders helps keep my feet warm even in a cold environment

I recently bought a couple of pairs of these socks for work. Unfortunately, I found the reinforced heel and toe sections really uncomfortable to were.

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.
