All I have used are rubber boots for deer and turkey. They are nice at keeping the feet dry, and fairly warm. For bow season, I have a Pair of Redheads which I bought 3 years ago for about 80$ Well now they have a hole in the side which isn't repairable. They had about 400 grams of thinsulate in them. But I wish I would of got 800 for those cold mornings. But all and all they were are good boot for the money. Now since I need a new pair for bow season, I'm going to look at rocky's or LaCrosses!
I believe its important to have a good boot for hunting, and that cost really doesn't matter to me... you know spend the money and get a good comfortable boot. But the spring I bought a cheap pair of plain jane rubber boots. Twenty dollars are Gander Mt. They are exstreamly light, and no insulation. The weight of the boot is why I bought them! When you chase turkeys all day, there isn't anything better and a pair of extremely light boots. for the money, I think they are awesome!!
Good hunting Jason
