Podiatrists often prescribe orthotics for a patient that hasn’t responded to other measures, or they can be an initial choice of therapy. A standardized x-ray evaluation is performed, a history and physical exam are taken, and an impression casting of both feet is done. With all of this, a podiatrist then writes a prescription for the orthotic lab to make. Most patients find their orthotics can last several years even with daily use, and movement from one shoe to the other.
