The author presents a description of three geometric models to serve as a framework for establishing a numerical classification system of unlimited refinement for structural variations of the foot and foot types. Such a classification system may identify different forms (foot types) that may be closely aligned to complex movements of the foot (dynamic foot function). This may help in the diagnosis and treatment of biomechanical disabilities. Clinical evaluations are based on radiographic landmark data from weightbearing radiographs.
