If you are an "average student" like you claim, then go to medical school. Trust me: medical schools are filled with "average students." (and this goes for both MD and DO schools) Do something utterly amazing and original that will make you "above average", and you'll get accepted. This will require you to sit down, look at your community and see where you can start some intervention that others have overlooked. (READ: don't volunteer in an ER or do some other pathetic activity that 90% of premeds seem compelled to participate in)
Anyways, Podiatric Medicine was a great field in the past. Unfortunately, outside forces are crushing it and their applicant pool has dropped so dramatically that the schools no longer even require the MCAT in order to be accepted. I've received numerous e-mails from podiatrists trying to go to DO schools. Despite acceptances, they can't get funding because they have had to default on their podiatric school loans.
I don't want to completely discourage you from podiatric medicine because it is a rigorous, respected field and I readily admit that pods know more about feet than I will ever know. I just want you to closely examine the current state of the profession before investing your time and money.
BTW, when I was in college, a podiatrist changed my life forever. I was suffering from incredible back and neck pain that had practically stopped my athletic activities and was starting to impact my daily life. The pod built some custom orthotics for me, and I pretty much got my life back, thanks to her. As a result, I have the utmost of respect for pods and I sincerely hope that their professional situation will improve in the near future.
