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.

Many runners experience stress-related injuries due to impact forces on body parts, particularly the knees. Existing shoe designs either lack quantifiable impact force reduction or are too complex and expensive to produce. There is a need for a shoe sole design that effectively reduces impact forces without complicating the manufacturing process or significantly increasing costs.
- Optimized sole design: The design incorporates cylindrical elements in parallel rows, with each row having uniform stiffness, but varying stiffness across rows.
- Differential stiffness: The decreasing stiffness from the heel to the forefoot is tailored to reduce impact forces on the knee during running.
- Honeycomb internal structure: The 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.
