The art and science of fitting shoes.

The two primary components of achieving proper shoe fit are shoe shape and shoe size. Shoe shape refers to the shape of both the sole and the upper. Proper fit is achieved when shoe shape is matched to foot shape. Shoe size is determined by arch length rather than overall foot length. The proper shoe size is the one that accommodates the first metatarsal joint in the widest part of the shoe. A set of seven guidelines for achieving proper shoe fit is offered. Properly fitting shoes are important in avoiding foot discomfort and deformity, and are absolutely essential in patients with arthritis, diabetes, and other foot disorders.
