Discover the world’s warmest socks!

Our stylish thermal socks don’t just look the part. They’ll warm your feet like no other sock brand on the market. But how do they work and what maintenance is required between wears?

Let’s explore some frequently asked questions about Heat Holders thermal socks.

How do Thermal Socks Work?

Our cozy thermal socks will help your feet stay up to seven times warmer than traditional cotton socks can.

We’ve selected an innovative yarn designed in Japan. Resembling cashmere, this acrylic fiber creates high-performing insulation with the added bonus of wicking-away moisture to prevent cold and damp feet spoiling your day.

Creating thermal socks with a patented (extra-long) looped cushion pile and innovative knitting technology, you’ll notice that your new thermal socks have their own TOG rating.

Repeatedly brushing the inside of our socks means the warm air generated by your body stays nearer your skin for longer. It’s this combination of heat-holding material and production techniques that ensure your thermal socks preserve the most heat possible.

How are Heat Holders® Different to Other Thermal Sock Brands?

Unlike the competition, you can tailor the level of warmth your feet will experience. Think of it as dialing your home’s thermostat to the exact temperature required on any given day.

Feeling the cold more than usual? We’d recommend reaching for a pair of Heat Holders® ORIGINAL™ thermal socks. These are the chunkiest, thickest and warmest socks we make. They have a tog rating of 2.3; making them seven times warmer than cotton socks.

Looking for warmth when wearing socks with boots or casual shoes like sneakers? Switch to Heat Holders® LITE™ thermal socks for a medium thickness that’s practical and effective. Every pair of socks in this range offers a tog rating of 1.6; making them four times warmer than standard cotton alternatives.

Our Heat Holders® ULTRA LITE™ option is perfect when you want to team them with closer-fitting shoes and boots. Their tog rating of 1.0 means they’re still an incredible three times warmer than traditional cotton socks.

In a nutshell, we offer you more choice and customization suited to your daily needs.

What are Thermal Socks Good for?

Whenever you’re feeling the chill is the perfect time to pull on a pair of Heat Holders thermal socks. However, those living in cool climates or traveling north will especially appreciate having toasty warm feet and toes.

Off to the mountains? Trust in our socks during winter sports season for warmth. Now, you can focus on your performance, knowing your feet will stay snug on the slopes.

But our socks aren’t just for the colder months. Customers with diabetes or poor circulation are experiencing everyday comfort and helping to care for their feet, thanks to these innovative thermal socks.

How do I Wash Thermal Socks?

We’re confident you’ll want to wear your thermal socks time after time. To ensure they stay in the very best condition, wash them in warm water using the 104°F setting on your laundry machine. And remember to wash dark colors separately to prevent washing disasters.

Thankfully, there’s no need to use bleach or turn them inside-out either. And costly dry cleaning bills are a thing of the past. Keep your thermal socks looking their best and stay true to size by line drying them - avoid the tumble dryer and iron.

Are Heat Holders® Thermal Socks Battery Powered?

Never! We focus on comfort and practicality across our entire range.

This fuss-free approach includes our thermal blankets too. No batteries or bulky packs are required, meaning your feet can stay toasty warm without the discomfort, upkeep, or expense of electricity and batteries.

Due to the yarn and processes described above, you can wear your Heat Holders® products with ease. Simply pick out your favorite pattern or color and live your life, as no switches are required across our entire range.
