2. Description of the Related Art A conventional shoe keeper has a hollow hermetically sealed structure molded from a synthetic resin such as vinyl chloride into a shape that can be inserted into the inside of a shoe upper, or a foamed molded product such as a styrofoam having a solid structure. As in Japanese Utility Model Laid-Open No. 6-55410, a structure in which wooden insteps are connected with metal fittings has been used.

Although these shoe keepers are suitable for maintaining the shape of shoes, they are filled so as to close the inside of the instep, so that they are easy to remove moisture in the shoes that causes mold and the like. Was difficult to maintain. Further, when discarded after use, plastics and metals are treated as non-combustible waste, which is a cause of air pollution during combustion, which is a social and environmental problem. In addition, although there has been a bilaterally symmetrical shape using cardboard as in Registered Utility Model No. 3053573, it is difficult to insert because it is rolled and inserted into the instep of a shoe, and it is bent. When it is formed into an inverted U shape or arch shape when it is opened, a space-like gap is formed without hitting the shoe keeper side surface to the inner side surface of the shoe, and the shape retention effect cannot be achieved. Since the waist strength is weak and the spring-like elastic force is poor, the shape retention of the shoe is not sufficient, which is a practical problem. Other,
Some of them are made of a symmetrical pulp molding material as disclosed in Japanese Patent Laid-Open No. 10-234426. However, like a cardboard, the waist force is weak and the spring-like elastic force is inferior, so that the shape of the shoe is not sufficient and practical. It was a problem.
