ASICS use 3D computational models to better understand the role of stability in running shoes. Optimizing with simulation reduces the risk of lower extremity injuries for runners, as well as enhancing performance. Sole structure and heel eversion angle are particularly important for understanding stability. Alongside experimental methods, models created in Simpleware software for export to Abaqus simulation tools help ASICS reduce prototyping time and costs, as well as manufacturing waste.
