2. Description of the Related Art Conventionally, a shoe sole having an anti-slip function, which is particularly effective on a snowy road surface or a road ice surface during severe cold, is disclosed in Japanese Utility Model Publication No. 46-32432. A metal stud is provided at the center of the cylindrical projection, and the base thereof is embedded in the sole of the shoe to provide a slip-proof sole, or a rubber stud is used instead of the metal stud as disclosed in Japanese Patent Publication No. 4-76684. Although anti-slip shoe soles and the like having a grip property with respect to the ground used have been proposed, many of them have conventionally provided anti-slip metal fittings, for example, in Japanese Examined Patent Publication No. 63-66201 and Japanese Examined Patent Publication No. 3-16841. As in the method of manufacturing an injection-molded shoe, many shoes in which metal spikes are projected from the ground plane have been proposed.

In a shoe having a slip-resistant shoe sole as described above, generally, when attaching a spike metal fitting, a bolt is inserted into a through hole in a mounting surface of the spike and tightened and fixed. However, with this spike mounting structure, it is easy for water to seep from the bolt or pin attachment point or to seep into the foot contact surface side, and there is a tendency to form even small voids that will be flooded when worn for a long period of time. The discomfort caused by the protrusion is a problem. Also, in this type of spiked shoe, when the nail bites into the ground, a large ground reaction force is applied to the nail, and especially on icy snow roads and road ice surfaces, the surface contact portion of the nail cuts into the ground as much as possible. Since it is difficult to disperse because it is not obtained, it is easy to directly transmit the ground reaction force as a feeling of pushing up the sole of the foot, and it is desired to reduce this feeling of pushing up.

A manufacturing method by slush molding is known as one of manufacturing methods of shoes made of synthetic resin.
As a method for manufacturing this type of shoe, for example, a shoe outer skin is integrally formed by slush molding using a vinyl chloride resin for plastisol, and after the bottom portion and the inner sole of the shoe outer skin are bonded, the shoe outer skin and the lining material are formed. A method of forming a shoe by fixing the upper and lower parts of the shoe by sewing, that is, introducing plastisol into a metal mold such as nickel or copper, and heating it with a heating bath,
The outer wall surface of the mold, which corresponds to the portion requiring reinforcement of the semi-gelling layer of uniform thickness on the inner wall surface of the mold, is locally heated, and the meat of the semi-gelling layer is formed at the toe, bottom and heel. Methods of increasing thickness are known. The method of manufacturing shoes by slush molding of this kind has been widely adopted for manufacturing various shoes because the shoes can be mass-produced at low cost, and the waterproof and heat-retaining properties are good. Has a completely waterproof performance to prevent discomfort due to water permeation from the slipped sole, that is, the screw-threaded portion of the sole of the shoe formed by the above-mentioned slush molding, and especially the slip-resistant performance effective on ice and snow roads and frozen roads. At the same time, the present invention provides a slush molded shoe with anti-slip spikes in which the ground contact reaction force applied to the claw portion when the spike claw portion bites into the surface contact portion is alleviated and the push-up feeling that is easily transmitted directly is reduced.

The present invention relates to a slush molding shoe in which plastisol is introduced into a molding mold and heated so that a gelling layer is attached to the inner wall surface of the mold and the shoe skin and the lining material are integrally bonded.
