      Heatgen™ Knee High Socks is rated 3.6 out of 5 by 23.
      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 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.

      Rated 4 out of 5 by from So far so good These socks fit beautifully. They are long enough to reach the knee and stay in place all day without ending up around your ankles. They wash well too keeping their length and shape. I hope they will go on without becoming worn at the toe but as I've only had them a short while I cannot comment on longevity yet.

      Rated 4 out of 5 by from Heatgen Knee High Light weight but warm socks, ideal for wearing under trousers. The trick is not to pull them up to their full stretch otherwise they do reach over the knee which is uncomfortable. I haven't worn them yet so can't comment on how they behave after a wash or whether they stay up all day. The seam over the toes is a bit hard but I wear socks inside-out these days so I get the smooth side against my skin (or buy seam-free socks).

      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 5 out of 5 by from Lovely and warm I actually bought this item by mistake. I was rushing because I had an offer that was due to expire and clicked on the wrong item but I have kept them mainly because I got them at 33% less than the usual price so it was not worth returning them. However now I have worn them I am likely to purchase more pairs. They are very warm but not thick so I can still wear them with shoes and tight boots not just trainers. They are a little tight on my not insignificant calfs but not too tight.

      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?
