Abstract
Recently "Ride" is described as the perception of running shoes in the international running magazine. But it is difficult to evaluate the "Ride" perception by physical measurements. The purpose of this study is to find the relation between the "Ride" perception and physical measurements for running shoes. In this research, good and bad "Ride" perception shoes are prepared. The running motions using these shoes were captured and the energy due to MP Joint Torque was calculated. The results showed that the "Ride" perception of the toe-off phase tended to depend on the energy loss due to MP Joint Torque. The analysis of the energy found the optimal construction of the grooves in forefoot of running shoes.
