Great for smaller feet.

These are very nice socks, good quality and a lovely feel. Unfortunately for me they are too short in the foot length. After only half an hour, I had to take them off as they were hurting my toes. I take a size 7 shoe. I passed them on to a friend who takes a size 5 shoe, and they were fine for her.

Feels great but horrible colour!

Originally posted on marksandspencer.com (UK)

They feel great but the colour is not very good! Why don't you offer Black??? The "Nearly Black" is a sort of wishy washy grey colour and not very flattering at all. In fact, somebody asked why I was wearing a "Granny Grey"??? So disappointing...

Nice colour and finish. Feel just slightly firmer than the medium version. Slip down very little.

Nice socks but not very strong. I need to wear support socks and these aren’t really strong enough although better than nothing

20 den firm support socks

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These support socks are excellent - I can see my ankles again! So comfortable, even at the top of the calf and do not roll down. Wearing them all the day and legs feel so much more comfortable. Anyone with varicose veins or circulatory problems should be buying them. So reasonably priced too for 3 pairs.

Purchased 20denier natural colour knee highs to wear under a long dress to formal occasion. So pleased as now my feet and ankles will not swell and still look dressier than normal support socks. Can always rely on M&S !

Unwearable

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

These were easy to put on and fitted well. Unfortunately, within an hour the wide elastcated welts at the top of the socks had rolled up into a tight sausage, which was very uncomfortable and left a red indentation on the skin at the top of my calves which was still there the next day. I was worried that it would cut off circulation and increase the risk of blood clots - I had to break my journey to take them off, and get alternative socks from my suitcase. Maybe these are not 'one size' but 'slim leg only'?

Too firm

Originally posted on marksandspencer.com (UK)

Unfortunately I ordered the wrong support knee highs. These are too firm, really need medium only.
