A chiropodist is a doctor who specializes in feet. In other words, a chiropodist is a podiatrist.
If your heel hurts or you have a broken foot, who should you call? A chiropodist, of course. If you've never heard of a chiropodist, that's because this word, especially in American English, has been nearly eclipsed by its synonym podiatrist. The two words share the Greek root pod- (meaning "foot"). A chiropodist was originally a hand and foot doctor, but in many parts of the world today chiropodist is used instead of podiatrist to designate a foot doctor.
