These socks are soft, warm and comfortable. They stay up well without being too tight around the top. They look smart too.

Warm and a good fit. These are relatively new so the durability has yet to be proven. Good value.

Toasty toosies and peace and quiet

Originally posted on marksandspencer.com (UK)

My partner feels the cold a lot and often wear socks and bed socks at home or two pairs of socks when out and about during the day. Not with these Heatgen socks. One paisr and his tootsies are toasty warm all day. Great for ke too as I don't t have to put up with him moaning about the cold. Highly recommended.

These are a repeat buy. They are really warm and lovely soft material, unlike cheaper thermal socks. I have bought them as a present as I know the recipient really likes them.

I purchased these for a man in his mid-seventies who suffers from cold feet. He has found them to be excellent, and is pleased that they go well with his smart clothes and don't make him look as if he's going for a hike!

I bought these socks because I had chilblains. Something I have never suffered from. After 7 days the chilblains had nearly gone. Today I am free of them thanks mainly to the socks
