Shoe Sole And Manufacturing Method Thereof

Abstract

The present invention relates to a shoe sole and manufacturing method thereof, wherein the shoe insole comprises: a body that is formed by a space support so as to be inserted into a shoe and support at least a portion of a sole; and a finishing band that is joined along an open edge of the body to the circumference of the body so as close the open edge and allows a filler to be injected into an inner space of the body. Since the finishing band is closely lap joined along the open edge of the body by fusing, a joint part between the finishing band and the body receives a shearing force even when the pressure inside the body is increased by injecting the filler into the body, and thus the compressive strength of the joint part can be significantly increased. Accordingly, the sealing performance of the joint part can be further improved, and thus the usable life or performance of the shoe insole can be significantly improved.
