Abstract:
     The invention relates to an improved structure of movable spike on athlete shoes. There is an elastomer with a through hole provided at its center between the spike and the spike holder screwed on the sole. When the spike dowel is tightened onto the holder with a specified torque, the resilience of the elastomer increases the effective safety range of the pressing torque wherein the directional spike dowel can be used and adjusted to the required direction. The spike dowel thus secured will not get loose nor come off and has no free space between it and the holder, being water tight. The elastomer by its elasticity can absorb the reaction and vibration induced by impact with the ground during athletic sports.
