My heel pain turned out to be heel spurs and Plantar Fastitus (sp?). I found custom orthotics to be a big help as well as stretching and advil. The orthopedist did offer a cortizone shot in my heel (yuck!) which I will resort to if I have to before my first century ride. I would be interested to hear if your othopedist recommends orthotics in the bike shoes - mine did and it seems to work.
