PROBLEM TO BE SOLVED: To provide shoes wherein the shoe soles of the uppermost layers are partially exposed on the side of sole surface in injection-molded shoes having shoe soles having a double-layered structure. SOLUTION: When a shoe sole 21 having a three-layered structure consisting of the impact absorbing material 2a of the uppermost layer, the main sole 2b of an intermediate layer and the earth material 2c of a lower layer is integrated by injection molding, a design window X is formed to the bottom surface of a heel part so that the impact absorbing material 2a can be observed from a rear surface side through the design window X. At this time, design effect is enhanced by changing the hue of the impact absorbing material 2a and shoes having impact absorbing function are easily discriminated. Impact absorbing effect is accelerated by the cavity of the design window X. |
