Shoe upper and shoe

Abstract

Provided are a shoe upper and a shoe that have good fittability to the instep side of a foot and are capable of inhibiting the depression of the heal at the time of coming into contact with the ground. The present invention relates to, in one or more embodiments, a shoe upper, and the upper includes an instep cover for covering an instep side of the foot, the instep cover has a structure in which a tongue portion and an instep cover main body are formed as a single body, and a center portion of the instep cover in a width direction is substantially unstretchable in a length direction of the foot. The present invention relates to a shoe in which the shoe upper is integrated with a sole.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a shoe upper and a shoe, and specifically to a shoe upper and a shoe that have good fittability to the instep side and are capable of inhibiting the depression of the heel at the time of coming into contact with the ground.2. Description of Related Art[0002]With an upper of a sports shoe, usually, an upper main body and a tongue portion are separated from each other, and the upper covers an instep portion in a state in which the materials thereof overlap each other. In recent years, uppers for integrally covering the instep side have been proposed in order to improve contact with a foot. JP 2014-210179A discloses a shoe upper that is produced as a one-piece knitwear and includes a first partial region and a second partial region that have different elasticities, in which the first partial region and the second partial region extend in directions that are basically orthogonal to a longitudinal ...

AI Technical Summary

Benefits of technology

The present invention provides a shoe upper and a shoe that have good fittability to the instep side and are capable of inhibiting the heel from being depressed at the time of coming into contact with the ground. This is achieved by forming the tongue portion and the instep cover main body as a single body (bootee structure) and preventing the center portion of the instep cover located in the width direction from stretching in the length direction of the foot and the center portion of the instep cover in the instep cover.

Problems solved by technology

In the case of the shoe upper disclosed in JP 2014-210179A, although fittability to a foot with various sizes can be flexibly exerted due to the first partial region and the second partial region that have different elasticities being provided, it is not possible to inhibit the heel from being depressed after the forefoot portion or the midfoot portion has come into contact with the ground because the upper excessively stretches in the length direction of the foot.

With the shoe upper disclosed in JP 2014-131772A, flat knitting is highly stretchable, and thus the upper is likely to stretch in the length direction of the foot, and it is not possible to inhibit the heel from being depressed after the forefoot portion or the midfoot portion comes into contact with the ground.
