ABSTRACT:
Disclosed herein is a shoe sole having functions of correcting a gait, of absorbing shocks, and of mitigating partial side wear of the sole. The shoe sole according to the present invention includes a main sole, which has a front foot part provided with a soft front midsole and a front outsole, and has a rear foot part provided with a hard rear midsole. The shoe sole further includes a subsidiary sole. The subsidiary sole includes an elastic member, a rear outsole, which is coupled to the lower end of the elastic member, and a connection member, which is provided on the upper end of the elastic member. The connection member has an internal threaded part, which couples the connection member to the rear midsole, and stop protrusions, which are provided around the internal threaded part. The shoe sole further includes a coupling support, which is provided under the rear midsole. Stop holes corresponding to respective stop protrusions are formed in the coupling support. A through hole is formed in the coupling support at the center of the stop holes, so that a bolt can be secured into the internal threaded part through the through hole. Therefore, the orientation of the subsidiary sole with respect to the main sole is changeable, or the subsidiary sole is replaceable with a new one, depending on the characteristics of the gait of a user.
