Heat Holders

Whether you need thermal protection outdoors or some extra warmth and comfort at home, these Ladies IOMI Dual Layer Raynaud's Slipper Socks in Block Stripe Denim will make your life warmer.

IOMI FootNurse® thermal socks have been designed to help people living with Raynaud’s and alleviate the symptoms associated with the condition. Non-slip grippers on the sole of each sock keep you steady when walking on polished wood or floor tiles.

Heat Holders Dual Layer are among the warmest socks we produce. Using our unique manufacturing process, we put two Heat Holders Lite socks inside each other and bind them together to create a super thermal sock with twice the thermal protection and a huge TOG rating of 3.1. That makes Dual Layer even warmer than our Original socks and over eight times warmer than a basic cotton sock.

Heat Holders are proud to work in partnership with SRUK, who are dedicated to improving the lives of people with Scleroderma and Raynaud's Phenomenon.

I've tried various thermal socks for my Raynaud's, this is the only pair that's worked and actually kept my feet warm.

FAQs About Our Dual Layer 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 Dual Layer socks?

Heat Holders Dual Layer are among the warmest socks we produce. Using our unique manufacturing process, we put two Heat Holders Lite socks inside each other and bind them together to create a super thermal sock with twice the thermal protection and a huge TOG rating of 3.1.

That makes Dual Layer even warmer than our Original socks and over eight times warmer than a basic cotton sock.

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.
