Not much to add better that what was said already.
I have a pair of LaCrosse 800's. If you're moving, they're a bit warm, which in turn leads to cold feet when you quit moving.
I have also found a good pair of socks is equally important. anything to keep your feet from sweating.
I also use my Iceman's but they are cumbersome to walk in and not a chance of doing it quietly. They are pretty much for stand hunting and ice fishing.
