Agree with the advice above.
For Pod, its not the shadowing hour amount, it about how do you feel about going into podiatry vs other fields. This isnt MD where you get to pick a specialty later on down the road, get the highest paying Nuero or Spine surgical residencies if you do well on the test or barely pass and scramble into family medicine. A Pod, for better and worse, is locked in at the start. There are pluses and minuses to Podiatry vs other specialties, and it is up to you to do the research on it.
It is also one of the most rapidly evolving medical specialties. Laws are constantly being decided on the rights on a licensing podiatrist, that will have lasting effects for generations to come (again, for better or worse). I see podiatry very optimistically because there are some really quality students out there pounding the pavement for practicing rights. The old Pods "Eating their young" so to speak are retiring or dying out and will be when you are done with your residency in 7 years (really 8+ if you are getting started now). I feel bad for the pods getting out now, they suffered through the worst of the profession-the residency shortage, the lack of quality jobs, but that is changing by the year.
