Ah, the age old struggle of socks.
I find a simple pair of average socks is best for me.
2 socks = sweatsville(regardless of fabric. Tried everything)
Wool socks = sweatsville(despite all the claims)
Thin socks = sometimes ok, but only in summer
Thick socks = a bit sweaty, depends on fabric, weather etc and can take too much space in shoes/restrict movement
