Thin,warm and kneelength socks to gp under boots?

[Allthingspretty]

Need some longish socks to go undery new national treasure boots. Any suggestions?

I really like the ones from Hot Squash. They are thin enough to go under everyday boots rather than just hiking boots and you also don't notice them under skinny jeans. They were my life saved last winter and I have already bought another couple of pairs for this winter!

I got some great ones a few years ago from BHS which were knee-length and thermal but nice and thin. Just looked and can't see them on their website but they have some others that might work.

Uniqlo do socks as part of their Heattech range, (scroll down) they are amazing.

Not called national treasure...forgot the name.of the boots

National sugar..
