Knee Pain

incidentally, I always feel like my right foot is over-pronoating when I pedal—*I've tried to move the cleat out to stop my foot from rolling over, but it doesn't seem to work.
I've begun to think that I should switch to proper clipless road pedals on my geared bike as they spread the pressure out over a larger pedal (as opposed to mtb spd's)? Any thoughts?

stiffer shoes often helped, that is if you want to be able to use MTB spd's.
