So I examined all my winter gear and decided to look for warm socks. The trail led to Thorlos Extreme Cold socks on Amazon. Normally $25, got a pair for $21.14. Thickest socks ever especially in the ball of the foot and heel. They go over the calf and stay up. Life time warranty. Send em back and you get a new pair no questions asked. They are better than my merino wool socks....
