Great quality

Yes, I recommend this

Excellent value for money. You can wear them under a long skirt, great for aching legs. You can out a pair of socks over them for wearing with wellingtons or boots.

Not good

No, I don't recommend this

They sounded a good idea but unfortunately they slip down after a short time. Not worth the money

Best on the market.

Yes, I recommend this

I love these firm support knee highs. The firm support has a moulded heel giving extra support. Seen or unseen they do a fantastic job keeping my ankles in shape and preventing inevitable swelling when Im on my feet too long. As well as a help for aching calves they look super.

Disappointed

No, I don't recommend this

Bought for my elderly aunt. She said they were very hard to get on then after she had been wearing them for a few hours the tight elastic at the top was so tight it had caused her legs to swell up massively so no good for her.

I love these, just enough support, easy to put on and don’t slide down. I’m a size 6 shoe and they fit well

Not Fit For Purpose

No, I don't recommend this

They were just what I needed to help reduce swelling in my ankles but after only a few minutes wear I could feel them sliding down eventually ending up tight and wrinkled around my ankles which had the adverse effect. Totally not fit for purpose!!

Knee highs become ankle socks

No, I don't recommend this

Knee highs slide down during the day. Not doing their job of supporting.

Yes, I recommend this

Just the right consistency to not ladder easily. I love the silky texture. I wish you’d also make them in blue.

Would be great if made in wide fit

No, I don't recommend this

These are very good quality firm support knee highs. Unfortunately, although medium support knee highs 15 denier are also made in a wide fit option, as are non-support knee highs 10 denier, this is not the case for the firm support knee highs. Unfortunately, they are so tight around the top of my lower leg that they leave a deep red welt under my knee. You obviously appreciate that other women have larger legs than average as you supply wide fit in other knee high options. So my questions to you are - why do you not supply a wide fit option in the firm version of knee highs? And will you consider adding a wide option to your firm knee highs range in the future. If the answer to the second question is yes, I would be happy to buy many pairs in the future.

Fantastic Socks

Yes, I recommend this

These are really comfortable to wear and a game changer for me. Enable me to walk much further with a dodgy knee. Sheer enough to wear with a longer skirt. I’ll be buying these again

Adjustment required!

Yes, I recommend this

As with many knee highs these tend to creep down with movement. I read on another site that the solution is to put moisturizer on your legs. Hey presto, it works! Good compression without cutting off circulation.
