Make sure to get one of the thin moisture wicking socks to put on first to transfer the moisture to the warmer pair of socks. I have found this gives me quite a bit more warmth. I think mine are duofold brand. I'm sure there are other good ones.
explain, what kind of thin socks? and how do you know if they are moisture wicking?
I always just wear 2 pair of merino wool socks on super cold days.
always up for learning a new trick
