The footbed, also known as the insole, is the inner portion of the shoe that runs under the bottom of the foot. For better fit and comfort, it may have several layers of structure and structural components, as well as a removable sock lining. Some footbeds may be heat molded to give the wearer a semi-custom fit. Others can advertise memory foam that molds to the wearer’s foot as the shoe is worn. Footbeds, on the other hand, are not the same as custom orthotics made by a podiatrist to correct a person’s foot issues.
A full-sole leather shoe supports the arch properly and typically are used for dancers. It forces the dancer to work the foot and muscles while increasing strength in the feet and legs. This aids in the development of proper technique and the preservation of muscle memory needed for more advanced barre and center work.
