Great socks, but shrink terribly!

I have been buying these socks for some years. They never wear out. But that's because they shrink so much I have to replace them every other winter! I don't wash them too hot, or tumble dry them. They just shrink. I've searched for a replacement, but there isn't one. They're warm and good quality. However, after the second winter, they are literally no good. I'd give them away, but nobody could get their feet in them!

Good knee length socks

Yes, I recommend this

Expected them to be warmer, but otherwise just what I wanted. Wish they did more colours, something a bit brighter?

Lovely socks, they DO fall down eventually though!

Yes, I recommend this

Lovely, warm socks. As with all knee highs, they do fall down eventually though so could have a slightly wider, thicker band to keep them up.

Warm

Yes, I recommend this

These socks are a little big usually have size 6 /8 . They feel soft & time will tell if the knee high slowly slip.

Rubbish

No, I don't recommend this

I would have given them 0 if I could. Plasticky material and they fall down on first wear so the elastic is also useless. They are not the quality of the previous version of these socks. Don’t bother buying.

Okayish

No, I don't recommend this

Lovely and soft and warm, not too tight at the top. But they bobble quickly and leave bits on the floor, plus the heel wears out quite quickly.

comfortable to wear

No, I don't recommend this

The socks are comfortable and soft to wear, but I wouldn't say they're thermal, they're not actually that warm, because they're too thin.

Not for a low tox user

No, I don't recommend this

I had already taken off the label when I realised that these socks were coated in some slimy chemical that is supposed to be anti microbial. I live a low tox life these days so won’t ever be wearing these and feel really annoyed that they did this and made the notification on the label so small I didn’t notice.

Not a good item

No, I don't recommend this

Very large and do not stay up in shoes, or slippers. Do not keep feet warm, thermal is not a good word for them.

Kept slipping down!!

No, I don't recommend this

I wanted some warm knee length socks to wear with my walking boots for some extra warmth. Right from the start they kept slipping down and ending up around my ankles. Spent the whole walk pulling them back up. Never had this problem before. On the upside they were very warm.

They roll down!

No, I don't recommend this

I can't recommend these socks enough for their warmth, however they are very annoying as They roll down! The elastic at the calf is very loose, therefore I can only wear them with leggings, as they hold the socks in place.
