Abstract
A method of forming a shoe upper includes obtaining a mold defining a shoe component, spraying a polymer formulation onto the mold to form a sprayed polymer formulation layer, curing the sprayed polymer formulation layer to form a polymer film, removing the film from the mold, and incorporating the film into the shoe upper.
Claims7
A method of forming a shoe upper, the method comprising:
- obtaining a mold defining a shoe component;
- spraying a polymer formulation onto the mold to form a sprayed polymer formulation layer, the polymer formulation include a plurality of polymer droplets in solution;
- curing the sprayed polymer formulation layer to form a polymer film;
- removing the film from the mold;

3 more elements
A method of forming a shoe upper, the method comprising:
- forming a fabric material by spraying one or more layers on a mold, wherein the fabric material comprises fibers at least partially embedded within the one or more layers of the formed fabric material, and the mold comprises an array of substructures that impart substructures to the fabric material;
- and
- forming the shoe upper with the fabric material such that the substructures are provided on an outer surface of the fabric material.
