This paper presents optimized heel counter structure considering footwear stability by using topology optimization method. Stability is a very important property requirement in the design of running shoes, for injury prevention. For stability design, controlling the heel counter deformation is effective. However the direct designing is very difficult, because analytical conditions are affected by runners' individual styles and different shoe structures. In this study normal displacement of the heel counter is directly measured by using optical 3D deformation analysis system. Then analysis conditions are determined by the comparison with experiment result, and under these conditions heel counter structure is optimized. Finally the validity of the heel counter structure proposed is checked by 3D motion analysis system.
