ABSTRACT:
Preformed fitting pads are disclosed having a protective envelope enclosure with flowable fitting material retained therein. The enclosure is shaped and constructed to provide therein communicating reservoir and primary fitting sections constructed in operative relationship to each other, so as to selectively provide for, as desired, the deliberate transfer of flowable fitting material from or to a reservoir section or a primary fitting section, and to selectively maintain, as desired, a controllable or predetermined volume of fitting material in a primary fitting section, all without requiring that fitting material be introduced into the pad from an external source of supply or be removed from the confines of the pad. The fitting material confined in said primary fitting section provides desirable pressure-compensating support when and where needed. Footwear or ankle-covering boots are also disclosed which are designed and constructed to receive and maintain such removable fitting pads therein, and which also include therein other, separate and distinct, removable fitting pads.
