ABSTRACT:
A deformable, elastic insole liner is provided with height adjustment pads for shoes to independently support the heel area, the longitudinal arch area, and the metatarsal arch area. Each pad comprises a base pad and a plurality of thin stacking pads which completely overlay the base pad and any stacking pads, and are self stabilized thereby. The stacking pads may be removably stacked onto each base pad, without requiring a fixed means of attachment to each other, in order to achieve the proper height adjustment for an individual user. This enables an individual shoe to be separately height adjusted for any combination of heel, longitudinal arch and metatarsal areas. In addition, after an initial adjustment, a particular support can be further height adjusted after a period of time, as necessary. This enables the user to adjust a shoe to treat the initial support problem, and subsequently to readjust the support for ongoing changes in the arches and heel areas.
