A structure of reducing a weight and mitigating shock of a shoe is provided to reduce the fatigue of the user's sole and to prevent the user's body like a knee, vertebra, etc. from being uncomfortable. An elongated hole(11a) is formed on the upper part of the center in a longitudinal direction of the bottom sole that is bonded to the mid sole to reduce the weight of the shoe. Protrusions(11b) are formed to correspond to each other on the inner wall surface of the elongated hole on the position that corresponds to an arch portion of a user's foot to provide elasticity for the pressurizing force given from the mid sole. |
