Has anybody tryed, or have the new Korker 1200,or 600grs. thinsulate snow boots. They come with 2 different ice cleats & have a neat fast change on/off system, for easy use. Cabela's was carrying the 1200 series but sold out of them with a great mark down. I'm thinking about giving my old Mickey's a break. They are a great warm bought , & I have been wearing them for over 40 years. I would like to go with a lighter,but, warm boot .Getting to old for all this walking. Thanks, Don.
