I've been wearing the Bean regular boots and most recently the insulated ones for years for rabbit, squirrel and deer hunting in Ohio and Pennsylvania. I get a size bigger boot than I normally wear for better confort with heavier socks and room enough for my arch supports. The Bean boots are flat as a board inside thus the need for the arch supports. One thing I always do is not lace them up too tight. Just enough to keep my foot from sliding around in them. Otherwise, if they were laced up tight my feet would freeze up.
