I like them but they have their limitations. You don't want to have to walk a long ways in them. They are a little heavy. You will also need cleats/ice grippers of some kind on ice without much snow, very slick. If you are going to be inside a shack they may get too warm. If your feet are on the ice they are great.
Oh and don't put on double or heavy socks, your feet need some room in them.
