I don't think podiatry fellowships will ever be as prevalent as they are in the allopathic world, where a general Internal Medicine resident can do a fellowship to become a GI doc, a cardiologist, an endocrinologist, etc. In contrast, a podiatrist who does a fellowship...is still a podiatrist, just more knowledgeable. It doesn't change your scope of practice/salary nearly the same way. That being said, I'm sure doing a biomechanics fellowship would make you a more desirable hire for any practice
