Abstract
Provided is a shoe upper that includes an upper body including a region having elasticity, and a film arranged in the region, in which the film has a heat shrinkage rate of 30% or more at least in one direction. Also provided is a method for producing a shoe upper that includes: a preparation step of preparing an upper body including a region having elasticity; an arrangement step of arranging a film in the region of the upper body, in which the film has a heat shrinkable rate of 30% or more at least in one direction; an attachment step of attaching the upper body to a shoe last or foot; and a heating step of, after the arrangement step and the attachment step, heating the upper body with the film arranged thereon to thereby allow the film to shrink to conform to the shoe last or foot.

A shoe upper comprising:
- an upper body including a region having elasticity;
- and
- a film having ends, wherein only the ends of the film are directly attached to the region via a fastening member, the film being heat shrinkable in at least one direction of the film in a state of being attached to the region, and the film having a heat shrinkage rate of 30% or more at least in the one direction of the film in the state of being attached to the region.
A shoe upper comprising:
- an upper body including a region having elasticity;
- and
- a film arranged in at least one of an instep region and a medial longitudinal arch region of the upper body, the film having ends, wherein only the ends of the film are directly attached to the region, the film being heat shrinkable in at least one direction of the film in a state of being attached to the region, and the film having a heat shrinkage rate of 30% or more at least in the one direction of the film in the state of being attached to the region.
