[Shoe sole member]
The shoe sole member has a structure in which the outsole, the insole, and the seam allowance protrusion are integrated. The shoe sole member has an insole and an outsole integrated with each other, and has a seam allowance protrusion for sewing the entire circumference of the lower edge portion of the upper portion on the outer peripheral edge thereof. The outsole and / or insole and / or seam allowance protrusions are made of the same material or different materials. As the material, a foamable or non-foamable material having elasticity such as a synthetic resin or a rubber material having a cushioning property even at a low specific density and a relatively high flexural modulus is used. It is also possible to manufacture the insole and the outsole with different materials. In the case of different materials, the insole can be a material that is excellent in absorbing the impact from the floor, for example, a low-resilience foam, and the outsole can be a material that is flexible but has excellent friction resistance.
Ethylene-vinyl acetate copolymer and polyethylene foam are exemplified as preferable ones, but the friction resistance property can be improved by mixing a rubber material. For molding of shoe sole members using these foams, a rubber material is mixed with a resin such as an ethylene-vinyl acetate copolymer and / or polyethylene, and further, a cross-linking agent, a foaming agent, a filler, and other additives are added. The added / kneaded product is heated with a mold or the like to form a foamed product by cutting, or the foamed product is heated and compressed by a molding mold and then cooled to shape the shape. It is not limited to the above-exemplified ones.

[Seam allowance protrusion]
The seam allowance protrusion is a flange shape that protrudes outward from the end face of the outer peripheral edge at the boundary position between the outsole and the insole, or a cup insole that forms a bank portion in which the peripheral edge of the insole extends upward. It has a shape. In the flange-shaped seam allowance protrusion having a flange shape protruding from the outsole or the insole, the upper part forms the insole from the seam allowance protrusion, the lower part forms the outsole, and the seam allowance protrusion. , Outsole and insole are integrally formed. It is preferable that the thickness and the protruding width are within a range in which the upper can be locked by contacting and the room shoes are not damaged during the period of use.
In addition, the cup insole-shaped seam allowance protrusion surrounds the insole that is integrally formed with the outsole, and the seam allowance protrusion rises from the periphery of the insole, and its edge is along the upper of the shoe. The thickness and protrusion width of the hem are within a range in which the upper can be locked by contact and the room shoes are not damaged during the period of use. That is, the seam allowance protruding portion and the upper portion are sewn together with a width and thickness that can be sewn together, and the seam allowance protrudes outward or upward. It is desirable that the inner surface of the bank portion is inclined along the outer surface of the foot, and that the outer surface thereof has a shape suitable for upper and sewing. It is preferable that the thickness and the upward extension length are within a range in which the upper can be locked by contacting and the room shoes are not damaged during the period of use.
Further, it is desirable to make the outsole and the insole with the same material because the manufacturing method is simple. The material of the seam allowance protrusion is not particularly limited as long as the upper and the seam allowance protrusion are sewn together and have durability for use as room shoes.

[Outsole]
The outsole has a structure integrated with the insole and the seam allowance protrusion, which are made of the same material or different materials. The surface of the outsole that contacts the floor is formed with an uneven pattern (groove) that prevents slipping. The outsole is an insole having a seam allowance protrusion, or a laminated insole and a seam allowance protrusion, and a highly anti-slip outsole molded product engraved with an uneven pattern is joined, or three of them are joined. It can be manufactured by molding at the same time.
When a foam of ethylene-vinyl acetate copolymer (EVA) mixed with a rubber material is used as the material of the outsole, an outsole having excellent lightness, slip resistance and excellent wear resistance can be obtained, but it is limited to this. Not done.

[Insole]
The insole has a shape whose surface is suitable for the structure of the sole of a human foot, as is the case with the insole having a seam allowance protrusion. The contact surface side with the foot is preferably provided with a convex curved ridge that supports the medial longitudinal arch, lateral longitudinal arch and lateral arch of the skeleton of the foot, which are ridges to reduce wearer fatigue. It is a department. Further, the outer peripheral portion on the contact surface side with the foot may be provided with an outer peripheral ridge portion for enhancing the stability of the foot. In this case, a gently rising ridge is formed on the side edge along the peripheral edge. By forming this outer peripheral ridge, the holdability of the foot is improved. By preventing the foot from moving or shifting from the insole surface in this way, the position of the foot can be stabilized and the comfort of wearing can be improved.
When a foam of ethylene-vinyl acetate copolymer (EVA) mixed with a rubber material is used as the material of the insole, it is excellent in light weight and has cushioning property, so that the tiredness of the foot is reduced, but it is limited to that. Not done.

A cloth can be attached to the contact surface side (the surface of the insole) of the insole member of the shoe sole member with the foot. In that case, since the surface of the insole of the room shoe is covered with a cloth or the like, it comes into contact with the back surface of the wearer's foot, and the flexible fabric and the cushioning effect of the insole can improve the comfort of wearing. It is desirable to attach the cloth before sewing the lower edge of the upper portion using the seam allowance protrusion.
