As shown in No. 2-8574 and Japanese Unexamined Patent Publication No. 49-87459, a porous material is adhered to the lower surface of the midsole of a shoe cover consisting of a shoe cover and an insole, and a sole is injection molded on the lower surface of the midsole of the shoe cover. A method of embedding a porous body in a shoe sole is generally known.

阻害していた。However, when the sole is injection molded with vinyl chloride, a copolymer of ethylene and vinyl acetate, thermoplastic rubber liquid polyurethane, etc., the porous material is bonded to the lower surface of the midsole by the heat of melting or reaction heat of the sole molding material. When the porous material is heated, the air bubbles contained in the porous material expand, or if the porous material is a synthetic resin or rubber foam, the blowing agent remaining in the porous material may be thermally decomposed during the molding process. Gas is generated from within the porous body, and this gas has no place to escape, causing the adhesive surface between the inner sole and the porous body to
As the heat is concentrated on the adhesive surface and thermally expands at this adhesive surface, the adhesive between the inner sole and the porous material tends to separate due to the expansion pressure, and in the finished product, the inner sole rises above the sole, significantly impairing the comfort of the shoe. Was.

A method of attaching the porous body 2 to the lower surface of the midsole of a shoe cover 1 consisting of a shoe cover 1 and an inner sole 12, injection molding the sole 3 on the bottom surface of the shoe cover 1, and embedding the porous body 2 in the shoe sole 3. , prior to the injection molding of the shoe [3, the inner sole 12 is placed in advance at the position where the porous body 2 of the inner sole is attached.
The gist of this is a shoe molding method characterized by forming exhaust holes 121, 121... that pass through the shoes.

後、針、錐、千枚通し等によって行ってもよい。The adhesion position to the lower surface of the inner sole of the porous body 2 is as follows:
2. The adhesive may be limited to the heel, heel area, etc. on the lower surface of the insole, or the entire lower surface of the insole may be adhered. If the fabrics 21.22 are glued on the top and bottom of the porous body 2 in advance, the fabrics 21.2
2, the porous body 2 is reinforced and the fabric 21.
22, the midsole 12 as well as the injection molded sole 3
The adhesion strength is significantly increased. The exhaust holes 121 and 121 may be formed in the inner sole 12 at the same time as the cutting process of the inner sole 12, or after the porous body 2 is glued to the lower surface of the inner sole 12, it may be formed using a needle, awl, an awl, etc. good.

Therefore, the gas that has no place to escape is concentrated on the bonding surface between the insole and the porous body, unlike in the past, and the expansion pressure of the concentrated gas does not cause the bond between the insole and the porous body to separate. It is possible to provide shoes that are comfortable to wear without lifting up from the sole 3.
