Re: "9 wide, 6 long"
Safety boots are the easiest for me, given my flippers. Sure, my toes don't get within 3 inches of the end, but the steel toecap stops the front collapsing in and looking weird, and to all outsiders, my feet look a bit big but otherwise normal. It's only when I take them off that people notice that the feet are wider than they are long. Also, Steelies are handy when working with horses, cars and heavy racks, although I also have shiny ones for when I'm trying to look civilised.
Ski-boots. Now they're the enemy.
