If I may ask, what shoe were you using before that and what sort of problems made you switch? How long did it take to get used to the Vibrams?<p>I have a flat foot (over-pronator) and am using stability shoes along with specially made orthotics. For the past five years I have been experiencing different levels of pain in my left shin. Nothing helped (changing shoes, orthotics).<p>Now I'm trying barefoot running. Very low mileage for now and lots of strengthening exercises. Will report positive results - if any.
