      180 Denier Heatgen Plus™ Thermal Knee Highs is rated 4.1 out of 5 by 52.
      Rated 3 out of 5 by from Cosy but not so comfy round the toes! Loved these socks, lightweight with a cosy layer on the inside. They are constructed like the bottom half of tights, having no heel and there is a seam around the toe area. Sadly, after wearing them for an hour or so, the seam round the toes started to dig into my toes, which was most irritating and not very comfortable. Being made of fairly thick material the toe seam is quite bulky, and however often I adjust the seam back under my toes they ride back upwards across my toes, not very comfortable when wearing shoes or boots.

      Rated 2 out of 5 by from Very uncomfortable I bought these to go dog walking in frozen weather. The seam at the toe is in such a bad position that it rubs my toes. They are completely unwearable for me and I'll have to bin them. Please beware.

      Rated 2 out of 5 by from Warm yes, but uncomfortable Although they do keep one's feet warm, they are poorly constructed around the toe area. They are bulky and have no definition so whether worn with boots, or ballet pumps they "bunch" up and cannot be smoothed. I have decided I can only wear them at home, which defeats the purpose. Also, at £6 a pair they are overpriced. Why, when you can produce comfortable knee highs with a high denier, can you not improve on this style? Quality control needs to be improved.

      Rated 2 out of 5 by from Uncomfortable socks These socks are so uncomfortable because the seam at the toes is in the wrong place: across the tip of your toes. Normally a sock seam is across the top of your toes not at the end. Very odd! This makes wearing shoes painful! A shame as these are made of a beautiful, quality, warm fleecy fabric.

      Rated 3 out of 5 by from Cosy Just what I have been looking for, the feel is lovely so soft. However the toe seam is so bulky it just makes them very uncomfortable to wear, if I hadn't thrown the packaging away sadly these would have been returned.

      Rated 5 out of 5 by from MY FAVOURITE PRODUCT OF THE WINTER/YEAR! Cannot emphasise enough how I love these thermal knee highs. I have bought 4 pairs and just about to order another! They hold up, they are fleecy, comfy and warm. I am unsure why people say they are bulky/uncomfortable where the toe seam is as I cannot even feel the toe seam! Perhaps just need to check the seam is in the right place on your foot! Best thing M&S have ever brought out. Cannot understand why they are only available online though and not in store. The next best thing would be for M&S to bring these out in navy blue and other colours!

      Rated 5 out of 5 by from Luxury Beautiful smooth and very warm knee length tights. Bought 4 pairs on a M&S multiple offer day so very good value for money. Only 5 foot tall so they do pull over my knees but I don't mind as I want to wear them either under trousers or with a long skirt with boots perfect!

      Rated 5 out of 5 by from Light but warm socks These socks are very light to wear but are very warm. As the material is thin they are perfect when taking on holiday as they do not take up much room. I am able to wear these socks with my normal shoes.
