This project focuses on designing and optimizing a high-efficiency running shoe sole pod that maximizes energy return. The team is conducting detailed research into pod geometry, material behavior, and energy storage mechanisms to create a system that significantly outperforms traditional foam soles. Using COMSOL and MATLAB, the team models the hyperelastic deformation and fluid-structure interactions within the pod to predict how it will behave under realistic forces during running. To validate these simulations and assess real-world performance, a custom mechanical drop test apparatus has been built to accurately measure force-displacement behavior, energy return, and fatigue resistance. This testing system allows for direct comparison between physical results and COMSOL simulations, helping refine both the design and the accuracy of the models. By combining computational modeling with precision testing, the team is working toward an optimized sole pod that improves energy efficiency and contributes meaningfully to the development of next-generation running footwear.
