Heatgen™ Thermal Knee High Socks is rated 3.2 out of 5 by 35.
Rated 1 out of 5 by from 2 pairs faulty I bought a pair of these socks and they are comfortable and warm but being one size they don't have a proper heel. After one wearing the left foot had a hole in the toe. I took them back to the store and didn't want a refund so I opted to take a 2nd pair. The same thing has happened with the them. I hole in the toe (not the same foot!) I also bought a couple of pairs of thermal tights and have not had a problem with them. I checked that I didn't have any sharp toenails that could have contributed to this so this wasn't the problem. I think they are of poor quality and will be asking for a refund

Rated 1 out of 5 by from No warmth Sorry to say, these heatgen knee high socks were very disappointing. (bought a previous of pair of thicker knee length socks, great warmth but slide down!) I could feel the cold in my foot and ankle area (very bare). bought another pair for my daughter told her not to wear as i will need to return them. For milder months fine but i bought them specifically for winter so not suitable for that. surprised they didnt live up to the description. sorry.

Rated 1 out of 5 by from Warm but they are over the knee, not knee high I bought these socks to wear with wellies and although they appear well made and nice and warm, they go right up to the middle of my knees and beyond (and I am at least average height of 5' 7"). I was expecting knee high socks to go up to just below my knee joint and these are longer than that. I found them uncomfortable to wear, with the elasticated part that holds them up going right across my knee joint - they were so long I had to fold them over at the top and that made them even more uncomfortable. I had nothing else suitable so I had to wear these, but I would not buy them again.

Rated 1 out of 5 by from Disappointing Heatgen socks ! I had a pair of these socks from a couple of years ago. I thought they were very good for Winter, under boots, because they are not too thick, yet warm and comfortable, so I decided to buy 2 more pairs. What a disappointment ! The tops of the socks are much tighter than my older pair, so I know they would not be comfortable, even though I have fairly slim legs. I have returned them. So disappointed !

Rated 3 out of 5 by from sizing all wrong I am a short lady~ barely 5f t1" and as with all socks not only from M&S but also from many other retailers the sizing is completely wrong ~ far too long in the leg but more importantly the actual foot sizing which means the heel of the sock is half way up the back of your achilles. A size 3 shoe is significantly smaller than a size 5 1/2. I usually have to buy childrens socks in order to get a comfortably fitting sock, but then they have to be ankle socks because of the width of the calf. Why can't manufacturers make socks to fit specific shoe sizes like 4-4 1/2 etc?

Rated 3 out of 5 by from Heatgen Knee High Socks I ordered 6-8 size (my normal shoe size is 5.5). They fit OK on the foot and the leg length was fine but the elastic cuff was far too tight. I tried them with shoes and they were comfortable and warm but the mark on my calf after a few hours was worrying. I am only a size 8 with slim legs. I have hand washed them and tried to stretch the cuff but not successful.
