10 1/2 wide
This doesn't really have anything to do with how big my feet are, but it's related so I thought I'd mention it:
I wear the same 10-dollar K-Mart boots year round. When they need to be replaced, I go to K-Mart and buy the same 10 dollar boots. Every... single... time.
I haven't worn a different kind of footwear (not counting the slippers I occasionally throw on when I'm running somewhere really quick) since the 9th grade.
Jeez, I have about 5 or 6 pairs, dependant on what colour shirt I'm wearing!
