Nowadays trail running which is a running on rough roads in forest and mountain is in fashion. Footwears' requirement properties depend on applications. For instance requirement properties of running shoes are cushioning, stability, forefoot flexibility, fitting and so on. However the direct application of the running shoes designing method to the trail running shoes is not valid. The purpose of this paper is the proposition of the trail running shoes evaluation method. Motion analyses under various sloped down hill running (SDHR) are performed and compared with acceleration histories obtained from shank. It is confirmed that footwear stability on SDHR could be evaluated by the acceleration history. By using the acceleration history, stabilities of 5 typed shoes with various midfoot torsional stiffness are evaluated and the relationship between sole stiffness and stability on SDHR are discussed.
