In the present study, we measured 3-axis force at other 3 points on studs of soccer shoes. To fabricate sensors with a diameter of 1 centimeter, we used MEMS (Micro Electric Mechanical System) 3-axis force sensor chips. These sensors made us possible to understand the force distribution when a soccer player performed the kicking. The force distribution was different from how the player approaches to the ball. At the first half of kicking motion, 3-axis forces were applied to outside and backward area of the sole affected the ball speed. The direction of shear force also influenced the ball kicking. We examined better movement of support leg for kicking a faster ball.
