Very warm and they do stay up, but my legs are a little too short for these, so I should have bought some slightly shorter versions.
Mens Original Bigfoot Long Socks - Black
Very good value, socks wear well, quick delivery in time for Christmas, always good service from Heat Holders, highly recommend.
I have been buying Heat Holders for maybe 20 years, and have always liked them. One minor complaint was that "long" was perhaps 2-3 cm too short for my height (not all that tall at 1m84). In my newest socks that seems to have been rectified and I am completely satisfied.
These are the warmest socks I have ever owned%2C just buy them you won’t regret it. I now have 6 pairs and the slipper sock things.
