A method for manufacturing an article of footwear, comprising:
- providing a first plastic to a first shoe mold to yield a heel insert substrate;
- placing the heel insert substrate into a second shoe mold;
- providing a second plastic to the second shoe mold to overmold the heel insert substrate and yield a shoe;
- wherein the first plastic has a greater hardness than the second plastic;
- and
- wherein a portion of at least one of the first plastic and second plastic extends from a sole structure to at least a portion of a rear heel collar of the shoe.
A method of manufacturing an article of footwear, comprising:
- injecting a first plastic material having a first hardness into a first mold to form a heel insert;
- injecting a second plastic material having a second hardness into a second mold to form an upper heel substrate;
- injecting a third plastic material having a third hardness into a third mold to form a sole substrate;
- and
- positioning and uniformly molding the heel insert, the upper heel substrate, and the sole substrate into a fourth mold.
A method of manufacturing an article of footwear, comprising:
- placing a heel cup having a first hardness into a mold;
- positioning a heel cup overmold in the mold adjacent to the heel cup;
- the heel cup overmold having a second hardness;
- injecting a plastic material having a different hardness than the heel cup into the mold;
- molding the plastic onto the heel cup and heel cup overmold to form a shoe structure;
- and
- wherein a portion of at least one of the heel cup and heel cup overmold extends from a sole structure to at least a portion of a rear heel collar of the shoe structure.
