The impact force which runners receive passively during running reaches approximately 1.5〜5.0 times the body weight. The joint movements of lower extremity have strategy which absorbs the impact force. In addition, shoes have an important role of absorbing the impact force. This study investigated the relationship between the impact force and joint movements wearing different shoes. Eight subjects ran at 3.5m/s wearing 3-types of shoes with different shock-absorbing capacities. Shoes with thicker outer-sole were defined as shoes with higher shock-absorbing. GRF, joint angle, joint angular velocity, sole angle which is angle between foot and ground at touch down, and time of maximum joint angular velocity were sampled and computed. Time of GRF first peak and loading rate were longer and smaller significantly and knee joint angle at touchdown tended to be smaller when runners wore shoes with higher shock-absorbing. It was suggested that shoes with higher shock-absorbing attenuated the impact to the body and influenced running motion.
