[Conventional technology]

BACKGROUND ART Conventionally, there are slush shoes manufactured by a shoe manufacturing method such as the slush manufacturing method, which are similar to hand-sewn leather shoes with pressed edges manufactured by the Gutdewyer welt method, which is a type of shoe manufacturing method.

In this slush shoe, the pressed edge and the sole body were simultaneously molded from the same material.

[Problem that the invention attempts to solve]

By the way, as mentioned above, in these conventional slush shoes, the sole body and the sole body were integrally molded from the same material at the same time. law has been adopted. For this reason, in order to make different parts of the shoe, such as the sewing thread, the hem, and the sole itself, particularly in the case of a stitched hem, delicate painting work is required, which is time-consuming and costly. I couldn't do it.

The present invention was developed based on the background of such conventional technology, and it enables diversification of design and functionality, such as making the sole body and the pressed edge different and more sophisticated, as well as making shoes with pressed edges. To provide a slush shoe which can be easily joined to the sole body and which can also improve the strength of the joint between the pressed edges and the sole body at the non-stepping part on the side opposite to the other shoe. With the goal.

[Means for solving problems]

That is, the present invention provides a slush shoe that includes a sole body and a press edge provided at the joint between the sole body and the laces, in which the sole body and the press edge are made of materials having different material properties. The pressed edge is formed with a sole body side inclined joint surface that connects the upper corner in the inner direction of the shoe and the lower corner in the outer direction of the shoe. The present invention provides a slush shoe characterized in that a push edge side inclined joint surface opposite to the sole main body side inclined joint surface is formed at the joint with the shoe sole.

[Effect]

In the slush shoe of the present invention, first, the sole body and the push-up edge are made of different materials with different material properties. Therefore, it is possible to diversify the design and functionality, such as different colors of the sole body and the pressed edge, and higher quality soles.

Thereafter, the sole body and the push edge are joined by overlapping the sole body side inclined joint surface and the press edge side inclined joint surface. For this reason, there is only one surface of the press-on edge that connects with the sole body, making it easier to connect the press-on edge with the sole body, and since the press-on edge is triangular in cross-section, The push edge can be firmly joined even on the untrodden part on the side opposite to the other shoe which is curved.
