Perfect fit and super soft

Yes, I recommend this

Perfect fit. Super soft and a great alternative to black or plain grey knee highs. Purchased for my 90 year old mum. She loves them.

Warm and soft to touch

Yes, I recommend this

Lovely and soft to touch. Warm but the elasticated top is not the next as it edges its way down on walking. But good price.

Does not stay up

No, I don't recommend this

Socks constantly slide down my leg which defeats the purpose of wearing knee high socks

They fall down

Not enough elastic to hold them up so will return after Christmas. Same for the ankle ones but I've worn them now

Cosy socks

Great for wearing with boots under long skirt or dress and for wearing under jeans to avoid the gap between sock and leg when sitting down! They don't fall down even on a long walk, they are soft snd comfortable

Didn’t stay knee high for long!

No, I don't recommend this

I wore the knee high socks for about 15 minutes when they started slipping down my legs. I had to keep pulling them up which defeats the purpose of buying knee high socks. They felt soft and cosy but the ribbing at the top was not strong enough to hold them in place. I’ll have to keep the set in that I’ve already opened but the other pack of 2 will be returned.

Mid shin but very warm

Don’t stay up !!

No, I don't recommend this

Disappointed with these socks. They seem very short and don’t stay up. I wear a lot of knee high socks and not happy. They are warm however.
