I just got videoed from behind recently running on a tread mill during the purchase of running shoes. I run toes out, and my right foot wobbles left/right while in the air and plants with the foot tilted out. When I get knee pain, it's always the right knee.

I'm readjusting my cleats to allow my toes to point out more and may resort to the pedal extenders as well. I may experiment with cleat wedges.

My SPD cleats seem to allow adequate float to let my feet wander in their natural range adequately. I just need to make sure they are adjusted to the correct angle to pedal toes out.
