I've had good luck with rubber boots and I've hiked hundreds of miles in them. I used to wear them every day when I used to work in the woods and I didn't have an issue with sweat. I would wear them 9 months out of the year. Only in the summer would they be too warm. I had the Lacrosse Alphaburlys with 800 grams of thinsulate. I never got cold feet either, used them down to 25 degrees and in the snow. Sure is nice to never have to worry about wet feet. You don't want to do a lot of mounting climbing in them, but for a lot of your deer hunting, rubber boots are great. Just don't get the cheap ones. The good ones are $150 to $200.
