No, we do not use foam box to casts for orthotics because your foot changes when your foot is pushed into the foam to get the impression. This is particularly important for patients who over-pronate or have flat feet or fallen arches because the pressure applied to the foot will flatten the arch and thus not providing a proper cast. If the cast was done non-weight bearing (foot off the ground), the orthotic will be properly designed to support your natural foot without any weight on it. Many patients who previously have had orthotics done by the foam box method will notice a difference in their new orthotics.
