If you're looking for some very warm boots for iceboating, you might look at
www.iceboatersboots.comTheyre called 'iceboaters" and have iceboats on the side of the leather boot. More important, they're amazingly warm with a real wool fleece liner, and a heat-reflective layer under the insert. very nice boots. almost too nice to screw cleats into. so i'm snapping on removable cleats. let me know how they perform. this is my first season using them. all the best, jory squibb
