Dr. Comfort has expanded its custom functional insert line to include Exos advanced technology—a thermoformable material that allows practitioners to make adjustments quickly and easily in their own offices. Exos bondable material is thin, strong, easy to grind, and has a low thermosetting temperature that allows for adjustments to be made efficiently. The inserts come with an Exothermix heat patch that allows the practitioner to apply heat to the specific part in need of adjustment, at a temperature much lower than a heat gun. Most inserts are delivered less than one week from the time an order is placed.
