Abstract
The improvement of the pedestal of roller shoes, which is a technique in the field of sports shoes, provides the capability of shock absorption. The improvement of the pedestal includes the following features: the middle part of the joint shelf is mounted to the pedestal, a roller is mounted to the one end; the middle part of the spring steel plate is mounted to the appropriate place of the pedestal, the two ends of it mount to the other ends of the two joint shelves. This new design will absorb the shock imposed on the rollers via the damping of the spring steel plate, and prevent the shock from going to the feet of the user.
