I have big ol wide feet too.
I ended up buying the Cableas OUtfitters serires boot in the 10 inch height in 13 4E. All leather, but gore-tex and 1000 gram thinsulate. Only thing I have found I wish was different is the soles are made out of a real hard material that does not grip on slick or smooth ice at all, so some kind of grips are needed for traction on slick surfaces.
