Benefits of technology

The present invention provides apparatus and methods for manufacturing footwear pieces. The apparatus includes a footwear form with a location mark corresponding to the location of a strap rivet. The location mark can be a metal piece or a halo section that roughly corresponds to the size of the rivet. The location mark can cause a reduced amount of molding material to form at the location of the rivet, resulting in a hole or indentation in the formed footwear piece. The method includes forming a location mark in the footwear form and using the footwear form to mold the footwear pieces. The invention also provides molds for manufacturing sectional shoe pieces with a base section and a strap section that are attached by rivets. The strap section can pivot relative to the base section. The technical effects of the invention include improved manufacturing efficiency, reduced labor costs, and improved quality of the footwear pieces.

Problems solved by technology

In particular cases, this can result in a hole or an indentation in a formed footwear piece at the location where the rivet associated with a strap on the footwear piece is to be attached.

Embodiment Construction

[0032] Among other things, the present invention provides various molds and methods for using such to manufacture footwear pieces. In various cases, the footwear pieces are molded from a lofted material. Further, in various cases, the footwear pieces include a pivoting strap that can be moved into contact with and fixed in relation to the sole of the footwear piece, or moved into contact with and fixed in relation to the upper of the footwear piece.

[0033] Turning to FIG. 1, a footwear piece 100 in accordance with some embodiments of the present invention is illustrated. Footwear piece 100 includes a base section 110 and a strap section 120. Base section 110 includes an upper 150 and a sole 162. In some embodiments, base section 110 is molded as a single piece of foam material. In other embodiments, sole 162 is molded from a foam or other foam like material, while upper 150 is manufactured of a different material that is later assembled with sole 162 to form base section 110.
