ABSTRACT:
A method of making an article of footwear includes the steps of forming a foam shell for an article of footwear by wrapping a foam side wall around the periphery of a base, positioning the foam shell on a last, securing the last and the foam shell within a mold and closing the mold, applying heat and pressure to thereby mold the foam shell to the shape of the last, and then opening the mold and removing the molded article of footwear from the last. In a preferred embodiment, the method further includes the steps of forming an inner bootie, having an inner liner and a foam overlay, and inserting the inner bootie over the last prior to positioning the foam shell thereon. The inner bootie includes the inner liner with the foam overlay attached to selected regions thereof. The step of applying heat and pressure thereby includes molding the inner bootie with the foam shell to form the molded article of footwear.
