Great winter socks

Yes, I recommend this

Excellent socks, very warm but remarkably thin! As warm as the best thick Nordic socks that cost a lot more. Equally at home in a shoe or a boot, smart or casual. No more cold feet , well worth the money

Definitely warmer for colder weather

Yes, I recommend this

I bought these for myself as M&S don’t seem to make this thickness of Heatgen socks for women any more. I’m a size 6 and after washing/tumbling they fit nicely. Only gripe is, the elastic in the top can give way very easily. They still stay up but not as well. I like the material - very slightly thicker than a cotton sock but not bulky like most thermal socks.

Fine knit thermal socks that really work!

Yes, I recommend this

Brilliant, a lightweight, fine knit sock with thermal capacity. Much more comfortable than usual thick thermal socks and well priced.

Cosy warm winter socks

These are good. A small improvement on ordinary socks and not too thick and cumbersome. Good value too.

Perfect

Yes, I recommend this

Thin enough for two pairs, but thick and warm enough to be worn alone. Kept my son's feet warm and toasty whilst we walked round a chilly, snow covered New York!

Holes

All got holes in after 1 month of wear (ie 3 5 or 4 uses) but was for dog walks so a bit punishing.

Super soft, but not thermal

Yes, I recommend this

Bought because I wanted warmer socks than standard, however I wouldn't say they had thermal qualities. No warmer than normal socks, not as thick as expected. However, super soft, well fitting and comfortable.

No, I don't recommend this

My husband wanted some, thin thermal docks to be less bulky in shoes. He knows it is extremely cold at the moment but his feet was cold, just like he had his normal socks in
