1. I have Mucks that have Neoprene uppers and rubber bottoms and they are not good in cold weather. My feet get cold very quickly in them. In fact I just bought a winter pair of rubber boots with 1000 grams of Thinsulate because my feet were getting cold.

2. After sweating in them I put baking soda in them and spray them out. This is my 3rd year using them and they aren't "stinky" as far as I can tell.

3. Yes they are waterproof, but neoprene tears easier on thorns than rubber, but it won't crack like rubber.

All in all I like the boots, but I definitely need something warmer for cold weather hunting.
