1. A shoe assembly, comprising:
- an upper; and
a midsole assembly coupled to the upper, the midsole assembly having a heel impact region located to be under a heel of a foot of a wearer and a forefoot region located to be under a forefoot of the foot of the wearer, the midsole assembly comprising a molded foam material,the heel impact region comprising a non-linearly viscous, SEBS block copolymer-based material molded with the foam material and defining;
a generally circular heel portion; and
a tapered extension extending forward from the heel portion;
the forefoot impact region comprising a non-linearly viscous, SEBS block copolymer-based material molded with the foam and defining;
a generally oval-shaped portion positioned under an inside metatarsal of the foot of the wearer; and
an arcing extension extending laterally outwardly from the oval-shaped portion, wherein the arching extension is configured in an arcing pattern of metatarsals of the foot of the wearer to substantially underlie the metatarsals.

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.
