pr1or.art Inc., “Advanced Footwear Design: Customizable Performance Sole,” Published Technical Disclosure No. 24-11857026_0001_PTD, Published October 27, 2025, available at https://archive.pr1or.art/24-11857026_0001_PTD
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 of a footwear with a wavy shape in the peripheral portion of the heel, which improved the performance of the footwear. However, the original design had limitations in terms of durability and customization options. The present invention addresses these limitations by introducing reinforced components, a cushioning system, and removable and replaceable parts, thereby enhancing the overall performance and user experience of the footwear.

Novelty and Inventive Step

The present invention provides a novel solution to the limitations of the original patent by introducing reinforced components, a cushioning system, and removable and replaceable parts. The combination of these features provides a non-obvious improvement over the prior art, enhancing the durability, performance, and customization options of the footwear.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include varying the material and design of the reinforced toe cap and heel counter, or incorporating additional features such as adjustable lacing systems or customizable insoles. Variations of the cushioning system may also be explored, such as using different materials or configurations of air-filled chambers.

Potential Commercial Applications and Market

The enhanced durability and performance footwear has potential commercial applications in the sports and outdoor industries, as well as in the fashion and lifestyle markets. The customization options and improved comfort features make it an attractive product for a wide range of consumers.
