I used to date a guy that was a hiking/outdoor expert.

He said to wear thin(like men's dress) nylon socks first, then the heavier sock over those, as the nylon wicked away the moisture to the outer sock.

I still recall being in the Arctic when I was a kid and putting on the footwear to walk to school in - 60 F temps: heavy winter work socks, then the stitched duffel sock, THEN the tightly sewn and hand-beaded mukluks (done locally by people before it became a trendy tourist and fashion thing!). Mukluks had a drawstring right around the top - tie it up, and away you go. Light as a feather, and perfect outdoor/indoor wear! Never came off til we got home.
