I'm going to agree with the others, but will add that your socks will make a huge difference in your comfort level. Wicking moisture away from your feet is important and some heavy wool socks will allow you to wear shoes or boots with less insulation. And they can be changed for warm, dry ones much more easily than the boots can.
I would also like to ask big swede what a snow scooter is? Like a Vespa with skis, or is it what we would call a snowmobile, or Ski-doo?
