Love the material and feel but they don’t stay up and I don’t have skinny legs

I’m disappointed that these fall down - my legs are pretty average so not wide or narrow. I wouldnt say they were firm support either - more medium. If I hadnt had to wear a pair to work this out, they’d have been returned.

I ordered firm support knee highs - standard fit, but they keep slipping down. I end up looking like Norah Batty.

Not the best

Originally posted on marksandspencer.com (UK)

These seemed good value for money in the 3 pack, but don't perform well. They are easy to get on and off but don't give much support and do not stay up, I can't walk any distance and they are rolled down around mid calf level. Wouldn't buy again.l

Decent compression but they don't last more than two wears. Toe tore right through them.

My customers complain they have difficulty in getting their prescription support socks on, hence stop wearing them. These are better than nothing, & are great for mild fluid issues.

Good support Socks

These are really good for support. Wear well with reinforced heel. Not always easy to find in the shops so great to get them easily online.

I have previously purchased the firm support tights which I have found very effective for times when my legs and feet become swollen during the day.

I wanted 15 denier but they are only sold in large size.Tried these instead Good support 20 denier looks fine as they have a nice sheen. Would have preferred without reinforced heel

Would not buy again

Found these knee highs to be too firm around the top of the leg; after wearing for most of the day found they cut into my skin behind the knee and made the area very sore. On the plus side would say they are long enough in length and didn't fall down but unfortunately not for me.

These are great. I bought them for my 80 year old mum who has fluid retention in her legs and they have really helped with the swelling and pain. Her nurse practitioner recommended them.

Solved my problem!

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I am an older purchaser and am supposed to wear support stockings due to minor circulatory problems but the NHS ones I cannot manage to put on due to arthritis in hands!!! Conundrum!! So I tried these and they are excellent. Not as difficult to put on, they stay just below knee, feel firm and are helping my legs, especially in this hot weather! I keep a stock of these now together with the medium strength which are also excellent.
