The purposes in this study were to evaluate the contact area between the shoe sole and the ground in running by using a textile sensor and to determine the influence of sole bending stiffness distribution on the contact condition and center of pressure. A textile sensor is a flexible and thin sensor that has applied compression properties on the multi-layer fabric. The result of contact area obtained from the textile sensor corresponded to that from vertical coordinates of sole markers by using motion capture system. Center of pressure moved within the contact area during support phase. The velocity of center of pressure obtained by the shoe with a slit line under MP joint was small during kicking phase. In this shoe, the backward end of contact area moved forward. The shift of contact area is caused from the local bending of the shoes sole. The result indicates that the noncontiguous bending stiffness of a shoe sole prevents center of pressure from moving smoothly.
