This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,026.

Background and Problem Solved

The original patent disclosed a sole structure with fixed angles, which limited its adaptability to different foot types and terrain conditions. This invention addresses these limitations by introducing adjustable and dynamic sole structures that can be optimized for various scenarios, providing a more comfortable, efficient, and safe footwear experience.

Novelty and Inventive Step

The new claims introduce adjustable and dynamic sole structures, which are not present in the original patent. The inventive step lies in the ability to optimize the sole structure for various scenarios, providing a more comfortable, efficient, and safe footwear experience. The use of machine learning algorithms and self-cleaning mechanisms further differentiates the invention from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the invention can include different materials, geometries, and mechanisms for adjusting the sole structure. For example, the invention can be implemented using shape-memory alloys, hydraulic systems, or electromechanical actuators. Variations can also include different types of sensors and algorithms for detecting foot movement and terrain conditions.

Potential Commercial Applications and Market

The invention has significant commercial potential in the athletic, outdoor, and healthcare industries. The adaptive footwear can be marketed as a high-performance product for athletes, a safety-enhancing product for workers, or a comfort-enhancing product for individuals with foot issues. The potential market size is substantial, with opportunities for partnerships with sports brands, outdoor gear companies, and healthcare providers.
