Orthotics are "braces" that are external to the body, such as a knee or wrist brace. Foot orthotics are "insoles" that are inserted into shoes, to accommodate or correct the motions of the feet (known as biomechanics). Based on the philosophies of the practitioner, as well as the patient’s symptoms, some orthotics are accommodative, some strictly offer "arch support", and some can offer correction.
To manufacture a truly costume-made orthotic, a 3-dimensional "replica" of the foot must be produced. This process is called "casting", although plaster casts are not always the chosen method. With evolving technologies come many opportunities to capture the shape of the foot digitally. For reasons described in the casting section of this site, we feel plaster casting is still the gold standard.
