Stabilizing Sole Structure for Foot Alignment and Shock Absorption

The patent applies local quality by varying the thickness of the midsole and outsole at different portions of the foot. Specifically, the combined thickness is greater at the heel portion to provide enhanced cushioning and support where needed, while maintaining appropriate thickness at other areas. This localized thickness variation resolves the contradiction by providing targeted support without compromising overall uniformity.

The patent employs composite materials by combining the midsole and outsole made of different materials with different hardness levels. The outsole is made of a harder material to provide structural support and durability, while the midsole uses a softer material to absorb impact forces. This composite material approach resolves the contradiction by achieving both impact absorption and support functions through material selection rather than complex manufacturing processes.

The patent applies dimensionality change by extending the sidewall of the outsole above the footbed in the vertical dimension. This elevated sidewall creates a cradling effect that naturally aligns and stabilizes the foot within the footwear. By utilizing the vertical space above the footbed, the design achieves foot alignment and stability without adding complex internal support structures, thus resolving the contradiction between stability improvement and structure complexity.
