Glasgow Enthusiast
Snug fit, feels nice next to skin, padded but not too warm.
Expensive, heel seams on the Smartwool socks seem to be more noticeable then versions from several years ago and hence may not be as comfortable.

Tamworth Love the great outdoors
Worn every day for two weeks, with only occasional washing, they proved comfortable and warm, even when wet.
