In a similar way down comforters are wonderful (get the right weight).
Did you know people used to use sock suspenders to keep their saggy wool socks up before we started to use synthetic fibres for socks?
Bombas are one of the few brands I would recommend to anyone because they donate one pair of socks for each that you buy.
I tried less expensive wool socks, like from costco, and they were too warm and moist.
Then I tried darn tough wool socks and they are always warm and dry - even in summer.
The website says they're actually 38% polyamide and 2% elastane. I think they're 'wool mix' socks rather than wool socks.
EDIT: Also I see that the proportions differ based on the type of socks.
FWIW.
I think this is an unintended consequence of my meditation efforts to dissipate my annoyance reaction.
Also: most “wool” is polyester because it’s like 10 times cheaper.
If you wear cotton socks and they get wet you might lose tour toes.
Most wool is definitely not polyester. At least not in Scandinavia.
For around town, though, a cotton base layer and wool works pretty well.
I have been wearing cotton as my top base layer for a while, and it is not great at staying dry or drying out while damp.
I'd certainly choose it over any synthetic fabric, but once you go over that low mark, just about anything is better, e.g. wool, linen, help, silk, etc.
