靴本底２の肉厚に応じて決定する。Next, the manufacturing method of the present invention will be explained, focusing on the manufacturing process. FIG. 4(a) shows a male last 8 used in the present invention. The female last 8 is used to cover the shoelace 1 and keep it in a certain shape, and the overall shape is the same as the conventional one, but in the present invention, the part corresponding to the heel part is A convex portion 9 is provided on. The length of the protrusion is determined depending on the thickness of the sole 2 to be molded.

ョン性並びに衝撃吸収拡散効果を高めることが出来る。In FIG. 4(b), sole molding resin 14 is injected into the cavity 12 through the injection port 13, and the shoe sole 2 is injection molded. After the resin solidifies, the sole 2 of the shoe is molded in the shape of the convex part 9 of the male last 8 as shown in FIG. 4(c).
A recess 4 is formed on the inner surface of the heel. Pass the shoe opening 13 of the obtained injection molded shoe 16 through the recess 4 as shown in FIG. 4(d).
The cushioning material 5 is inserted inside to complete the product. Note that when making the most of the shape and pattern of the cushioning material 5, the cushioning material 5 may be fixed in the recess and the design may be directly expressed in the shoe, but the cushioning material 5 may be further inserted by further inserting the cup insole 17 to hide the cushioning material 5. At the same time, by utilizing the cushioning properties of the cup insole I7, the cushioning properties and impact absorption/diffusion effect can be further enhanced.

クッション材５を選定しようすれば、クッション材５を
凹部１５内に圧入するのみでその脱出を阻止できる。In the present invention, since the shoe outsole 2 made of injection resin has elasticity, it is possible to remove the mold even if a dovetail-shaped convex part is provided on the female last. By selecting a cushioning material 5 formed on the sole 2 of the shoe and having a tapered surface that matches the shape of the recess, the cushioning material 5 can be prevented from escaping by simply press-fitting it into the recess 15.
