I needed a good outdoor boot for Hunting and Fishing. I purchased these Rocky Blizzard Stalkers at Dicks Sporting Goods for 99.99. These boots come with 1200 grams of Thinsulate and are waterproof. These boots are very heavy for regular walking around in but I have taken them hunting and ice fishing in really cold temperatures with a pair of wool socks on my feet have never been cold. I have stepped in large puddles and streams while walking and when I take these boots off the only wetness inside is some sweat from my feet from having them on with a couple pairs of sox on. Rock has definately come out with a reliable and very reasonably priced boot here. I continue to wear these boots during the winter and will definately buy another pair if these ever wear down.
