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

Great length and fit

These are super soft, fantastic fit, especially considering I have larger width calves. Highly recommend.

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

I bought them because they looked knee high & warm. In fact they are very warm but not knee high.

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.

Just the job

Yes, I recommend this

Bought some last year, the sock monster that lives in my washer seems to have taken a liking to them, so have had to buy more.

Really warm!

Yes, I recommend this

Really warm and comfortable. I will buy more. They could be slightly longer and they weren’t noticeably wider even though I bought the wide ones.

Warm socks for winter days

Yes, I recommend this

I didn't actually keep these as I didn't like the mixed pattern, but I kept the same socks in black and can vouch for them fitting comfortably and keeping my feet and legs warm. That's what the four stars are for. One star removed because I didn't like the pattern.

Not great

No, I don't recommend this

These socks feel nice and soft, but don’t seem to be any warmer than ordinary socks and they don’t stay up for long if you’re walking around - falling down around the ankles and needing constant adjustment.
