Abstract
Shoes and shoe sole assemblies and associated methods of manufacture are disclosed herein. One aspect of the invention is directed toward a shoe and shoe sole assembly made of a non-linearly viscous, SEBS block copolymer-based material that becomes more resilient as more energy is applied. The shoe and shoe sole assembly is configured with a heel and forefoot insert configured to fit within a recess in a midsole. In other embodiments, the non-linearly viscous, SEBS block copolymer-based material is mixed with at least one other polymer in a foam. The midsole is formed with a heel impact region and a forefoot region made of the foam.
Claims7
A method of manufacturing a shoe sole, comprising:
- mixing a non-linearly viscous, SEBS block copolymer-based material with at least one other polymer to create a foam;
- molding the foam into a heel impact region and a forefoot impact region;
- and
- forming a midsole to receive the heel impact region and the forefoot impact region, wherein the midsole, the heel impact region, and the forefoot impact region comprise an insole surface configured to receive a foot.
