Not sure if this helps: I did switch to Looks - which are a wider pedal base.....didn't make a difference. I even thought about going back to platform pedals and a toe clip.......that might be a cheaper, better solution for you.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
