If you want to keep your feet dry,buy the rubber! I go with thinsulate 400grs. or less and use ice breakers in cold weather when Im on stand. As far as sent control I have mixed feelings on that issue. I play a little game of hide and seek with my lab. I through a stick in a corn or bean field and while he is retrieving it I run and hide the woods. Even with rubber boots on he tracks me down like a rabbit sitting in a brush pile. I feel the rubber is easier to eliminate your scent from than the leather and canvas hunting boot,but still takes some attention. good luck
