We can raise and lower our saddles, move them fore and aft, adjust our stem height, change our crank length, change our handlebar width, etc. But I've never seen any mention or mechanism for changing the width between pedals.

My feet tend to splay out a bit naturally, and I think my hips are kind of wide for my height. When I adjust my float so my feet are comfortable on the pedals, my heels come very close the clipping the chainstays or crankarms. I've felt sometimes like if my pedals were a bit farther away from the bottom bracket, I'd be able to pedal smoother. And I'm not a big guy (5'9"). Do big people have issues with pedal spacing? Why doesn't anyone offer a way to adjust this?

Edit: Yes, I've adjusted my cleat spacing. There just isn't much room for adjustment there. Do other cleat brands (I've got Look) offer more width options?
