Overall very good socks

Warm and snug and cosy - and comfy once they’re on and fiddled about with till the rubber bits are in the right place. I’ve found I have to turn the tops down a bit, otherwise the rim or edge or whatever it’s called, digs in a bit if it’s next to the skin, and leaves a slightly indented line around my legs. But I use them every day and wouldn’t be without them.

Slow delivery, but good quality

I ordered this item over a month ago, and it just recently arrived, I have no idea if this is due to the post office or the company itself. Regardless, the socks are incredibly comfortable and heat up quickly with minimal effort, which is very impressive given my current temperatures, I'm pleased with the product itself, but not with the delivery time.

Really comfortable and warm.
Wear as slippers ever day with good ,hard wearing soles .
Will always buy …excellent socks .

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.
