I'm gonna cast my vote for the Mucks. My pair of Muck Wetlands are at least four years old now IIRC. Couldn't tell ya if they are more scent free but they seem to me to be O.K.. But I don't do stuff like pumping gas with them on if I'm gonna hunt in them any time soon. They're great for walking but you gotta make sure they fit you and a pair of heavy socks. Two years ago the winter was super cold and the only time my feet ever got cold was sitting still in 12 degree weather during deer season (after the first hour I had cold feet). I also did a lot of work related outdoor walking and snowshoeing with them in sub-zero temps and never had cold feet as long as I was moving. I think if they had any scent on them it wouldn't stay on them as long as it would stay on leather/nylon boots. I retired last spring so they'll probably last me longer than I thought but if I wear these out I'd gladly get another pair of the same.
