For scent control and warmth, I like the lacrosse alphaburly sport insulated 100 or 1500. This boot is light weight and decently warm. Since it doesn't breathe, it is best for stand hunting. Another option is to the get the uninsulated alphaburly sport and use ice-breaker overboots for cold weather. I also put foot-warmers on my toes if it is really cold. If you are going to be driving/pushing, still hunting, or you just want a general purpose hunting boot, I like the Danner pronghorn or the Irish Setter Tamarack boot. I have both and they are both good solid boots.
