In all seriousness it’s an old trick used in the military, long before there was such a thing as hunting sock liners. and nylons were actually made of silk. But the cheap synthetic ones do the same thing pretty well
They are very thin, very snug, yet somewhat durable, and a good first layer sock. almost always synthetic. Thinner than that you'd be looking at panty hose type socks.
Personally i've switched to the thinnest/lightest weight darn tough(made in america/lifetime warranty/primarily wool sock) sock as my base sock, than do an additional medium/heavy weight sock over that. Haven't had a blister in 7 years. The big difference with darn tough is they come in actual sizes since it's impossible for a sock to properly fit a size 12 and size 6 foot.
