Many researches have been going on related to the activity of kicking in the foot ball. But there have been few researches to clarify the relation of the stiffness of a foot joint and its effect. In this paper, we focused on in-step kick activity which is performed quite often in the foot ball match. And we developed a pendulum like kicking model which is allowed to adjust the knee joint stiffness in the Sagittal plane to achieve the activity of left leg kicking. Then the experiments were conducted to clarify the relation of the foot stiffness and its influence including the velocity of the ball.
