Podiatry or podiatric medicine is a field of healthcare devoted to the study and treatment of disorders of the foot and lower leg.  

The titles “podiatrist” and “chiropodist” are interchangeable, with the term “podiatrist” becoming more favoured within the profession. 

So a podiatrist or chiropodist is a medical professional; a person devoted to the study and medical treatment of disorders of the foot and ankle; trained to assess, diagnose and manage foot complaints.
