Warm, not restricting, can use with dress shoes

Yes, I recommend this

I purchased these for my brother, who thinks they're excellent - warm, comfortable, not too tight at the top, and most importantly, they're not too thick for his dress shoes. A review by another customer mentioning this last point had encouraged my purchase.

Thermal socks

Yes, I recommend this

Bought these mens socks for me as the women’s version won’t stay up & neither do these so I knocked a point off. That said, it could be my boots that drag them down!! They are warm & very soft.

Brilliant warmth despite not being that thick

A relatively think sock for a thermal sock, but surprisingly incredibly warm. I'm finding it great on its own as well as finer undersock.

Good quality... and they really work!

Yes, I recommend this

Bought as a stoking filler for my brother, who gets through socks at a great rate. He reports back that they are a great fit, but more importantly, keep his feet warm!
