Method of manufacturing spray-on footwear

A method of constructing footwear comprising:

• spraying a first spray-on fabric onto a plurality of exterior footwear surfaces of a three dimensional last;
• applying a material to at least one of the spray-on fabric and the exterior footwear surfaces of the three dimensional last;
• allowing the first spray-on fabric to cure on the three dimensional last to form a flexible non-woven first fabric upper, the first fabric upper having a thickness extending from a first upper exterior to a first upper interior, the first upper interior being adjacent the three dimensional last;
• removing the first fabric upper and the material from the three dimensional last;
• and
• joining a sole to the first fabric upper.

A method of constructing footwear comprising:

• applying a spray-on fabric including a plurality of fibers on a three dimensional last in the form of a human foot;
• allowing the spray-on fabric to cure to form a flexible non-woven fabric upper;
• removing the fabric upper from the three dimensional last;
• turning the fabric upper inside out;
• and
• joining a sole to the fabric upper while the fabric upper is turned inside out.
