I'm like Jerry, my feet get cold easy.
Always wanted to try the military "mickey mouse boots" white version. I use one of the LaCrosse version of packs, supposedly rated to -80*F. My feet still get a bit chilly.....wish I'd found the ones rated at -150*F. The rating has got to be bull, but the insulation is heavier.
I like to sit for a while, AND I like to walk. I wear the thin poly socks under heavy wool. It helps.
PS-Jerry, How the hell you been??
