Abstract
Melded footwear and process for manufacture of footwear. This enhanced shoe can be formed and assembled with a limited number of steps and without the need for much stitching. The shoe has a durable polyurethane shell, which is an integrated upper and outsole. The shoe contains a textile upper portion which is attached by direct injection molded. Molding the textile to the outsole eliminates the need for the use of adhesives. A locking plug element is provided that serves the dual function of providing cushioning around the heel and locking certain elements together.
