It depends on how much you want to spend. I can't afford the very high quality of boots they have out there. I bought a pair of Whinchester rubber boots and they do pretty good. They also don't cost very much. The only bad thing about them is that they only have 200 grams of Thinsulate, but if you hunt where it is not very cold, then they will do fine.
