RE: Keeping your feet warm.
Do NOT wear cotton socks. That is the worst thing that you could possibly do. Wear wool socks, they will keep your feet warmer and help wick moisture away from the skin. I wear a pair of knee high rubber boots that has some kind of thin lining. Bought them at the COOP farm store for $40. They have to metal buckles at the top of each boot. For the money, best rubber boots I've found. Keep your toes moveing at all times when your sitting in stand. That helps alot as well.
