Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to shoes.

[0002]

[Prior art]

 A conventional shoe instep cover is known that is composed of a surface material made of non-stretchable materials and a backing material made of a flexible material, which are joined to each other.

[0003]

[Problems to be solved by the device]

 When a conventional shoe with an instep made of the above materials is worn, the instep feels good due to the presence of the insole backing made of a flexible material. When walking, the lateral protrusion behind the thumb base and the lateral protrusion behind the little finger base were pressed from both sides of the instep, causing discomfort and sometimes pain. This is because the width of the legs is widened in these areas and they are laterally overhanging. To avoid these problems, wide shoes should be made, but this is not preferable for women, because they lack smartness. It is also conceivable to use a stretchable material for the entire instep, but using such a material makes it impossible to make mechanical shoes because of the stretchability.

An object of the present invention is to provide a shoe which can solve the problem of pressure from both sides of the instep when the shoe is worn without damaging the appearance of the shoe, and which can be a mechanical shoe. It
