I also am plagued by my foot turning in, repeated bouts of plantar fasciitis, and lower back pain associated with gait problems caused by these occurences. Orthotics have helped some, but concentrating on posture is most effective. If you try walking with with your palms facing forward/up, you will see it naturally pulls your shoulders back and makes you more upright. it looks a little strange, but then so does all of our shakin'.
