An Outsole for a Running Shoe
Abstract

The invention pertains to a shoe sole design optimized to minimize stress injuries at the knee for runners. By incorporating rows of cylindrical elements with differential stiffness, the design aims to reduce impact forces transmitted to the knee joint during running. The sole features parallel rows of elements with varying stiffness, enhancing comfort and reducing the risk of injury.

Societal Impact

This technology can significantly reduce knee injuries among runners, promoting healthier lifestyles and reducing medical costs associated with running injuries. By providing a cost-effective and efficient solution, it can make high-quality, injury-preventive footwear more accessible to a broader population.

Salient technical features and Advantages of the Technology
  • Optimized Sole Design: Incorporates cylindrical elements in parallel rows, with each row having uniform stiffness, but varying stiffness across rows. 
  • Differential Stiffness: Stiffness decreases from the heel to the forefoot, tailored to reduce impact forces on the knee during running. 
  • Honeycomb Internal Structure: Cylindrical elements feature a honeycomb structure, allowing fine-tuning of stiffness based on size and density. 
  • Ease of Manufacturing: The design strikes a balance between effectiveness and simplicity, making it economical and easy to produce.
