The athletic shoe is very important equipment for athlete, because they bring out the best performance and also protect their legs from injury. Therefore the athletic shoe is generally required eight functional properties; cushioning, traction, flexibility, lightweight, fitting, durability, stability and breathability. Their properties depend on structure and material design of shoes. In the half-century, their properties have been significantly improved due to developments in new material. In this paper, it is introduced the history of material development and study of new material design about running shoes.
