Everything everyone else has said has been great. One thing I would like to add about keeping your feet warm is to not tie your boots too tight. I will even keep mine tied just tight enough to keep them sealed up. If you are walking all day you would have to have your boots tied on good so they don't move around. If you are like most deer hunters and sit for a long amount of time you want to make sure you have enough blood flowing to your extremities. Tight boots keep the blood from flowing to your feet and thus making them cold. Just my two cents worth.
