ABSTRACT:
Apparatus is provided for maintaining the tuckboard of footwear in a particular shape. The apparatus includes a tuckboard member made from a sheet of deformable material such as a fiberboard. Retention members are attached to the opposite surfaces of the tuckboard at localized positions such as where the tuckboard has been or is to be deformed. One of the retention members is in compression and the other is in tension. Each of the retention members may be thermosetting or a thermoplastic composite material formed from fibers (preferably non-woven) impregnated and covered with a thermoplastic material. The fibers may be made from a material selected from the group consisting of carbon, glass and aramid. The thermoplastic material may be an acrylic, nylon, polycarbonate or ABS. The retention members help to maintain the tuckboard in a particular shape. The retention members may be initially attached to the tuckboard, and the retention members and the tuckwear may subsequently be deformed to the desired shape. Alternatively, the tuckboard and the retention members may be separately deformed to the desired shapes initially and the retention members may be subsequently attached to the tuckboard. In either alternative, the inner sole and the outsole are then attached to the tuckboard. This embodiment has a particular utility to ladies shoes.
