A non-slip arc shaped sole is provided to prevent slipping by bringing non-slip cushion soles made of a thermosetting highly elastic body into contact with the ground before a rubber insole comes into contact with the ground. A lower surface of an arc shaped sole is formed to have an arc shape. A hard support is installed on the upper surface of the sole. A heel bottom rubber sole(3) in the shape of a horseshoe is attached to a heel part of a sole body(2). A front bottom rubber sole(4) is attached to the front lower surface of the sole body(2) except for the part corresponding to a big toe. Non-slip cushion soles(5,6) are attached to the bottom surface of the sole body(2) except for the parts to which the heel bottom rubber sole(3) and the front bottom rubber sole(4) are attached. |
