Rotatable midsole ambulatory footwear apparatus

Abstract

A method for manufacturing a footwear apparatus includes placing footwear upper material onto a bottom portion of a midsole mold. The upper material includes a first portion residing within a cavity in the bottom portion of the midsole mold and a second portion extending beyond boundaries of the cavity in the bottom portion of the midsole mold. The method further includes closing a second portion of the midsole mold onto the bottom portion of the midsole mold, injecting midsole mold material into the closed first and second portions of the midsole mold, where the midsole material is fused with the first portion of the upper material, and forming the second portion of the upper material into at least a portion of an upper of the footwear apparatus. The midsole material is attached to the first portion of the upper material without stitching or gluing.
