Evaluation method for running shoes’ outsole durability using a robot

<p>Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)</p> <p>Footwear brands develop a variety of running shoes with functions including shock attenuation, fit, stability, and durability. Among them, durability of outsole is one of the important functions all running shoes need and describes the resistance toward wear and tear. The outsole gradually wears out through running, but if it occurs too quickly, it is not acceptable for users. Generally, the most common evaluation method for durability is that runners wear a pair of shoes and run for a certain distance, several kilometers. As an evaluation method, it takes a considerable amount of time to complete, roughly two or three months. In addition to that, a further issue is the consistency of outcomes. No two runners are exactly the same, especially when it comes to running paces and foot strike patterns. Also, it is challenging to restrict running environments such as running surfaces for all runners. The purpose of this study was to establish a new evaluation method for the durability, specifically in the outsole of running shoes, utilizing a robot. </p>
