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 addressed the limitations of traditional footwear sole structures, but the new invention tackles the shortcomings of fixed-angle designs by introducing adaptive geometry that responds to user movement and terrain conditions. This innovation solves the problem of compromised performance and comfort in various physical activities and environments.

Novelty and Inventive Step

The new claims introduce a paradigm shift in footwear design by incorporating adaptive geometry, real-time adjustment, and machine learning algorithms, which are not obvious extensions of the original patent's fixed-angle design. The invention's modular design and customization capabilities further distinguish it from prior art.

Alternative Embodiments and Variations

Alternative embodiments may include the use of different types of sensors, actuators, or materials to achieve the adaptive geometry. Variations could also involve integrating the system with wearable devices or mobile applications to provide users with real-time feedback and performance tracking.

Potential Commercial Applications and Market

The adaptive footwear system has vast commercial potential in the athletic, outdoor, and wellness industries, targeting consumers seeking high-performance, comfortable, and sustainable footwear solutions. The invention's customization capabilities and modular design also open up opportunities for subscription-based services and product upgrades.
