Abstract: The object is to improve fitting and supporting properties relative to the midfoot region of the foot of the wearer. The upper structure 2 for the shoe 1 includes a stretchable inner upper portion 20 that has a forefoot part F to cover the forefoot region of the foot of the shoe wearer and a midfoot part M to cover the midfoot region of the foot, and an outer upper portion 21 that is less stretchable than the inner upper portion 20 and that is disposed outside the inner upper portion 20 and overlapped with the inner upper portion 20. In the state of a free length that the inner upper portion 20 is extended without slackening via its own weight when the upper structure 2 is inverted upside down, the inner upper portion 20 has a clearance e relative to the outer upper portion 21 at least at the midfoot part M.

Abstract: A shoe upper structure includes an inner upper having a foot-dorsum top portion that covers at least a dorsum top region of a foot of a shoe wearer, an outer upper having a heel portion that covers at least a heel region of the foot of the shoe wearer, and a stretchable portion that generates a tensional force to the foot-dorsum top portion of the inner upper toward a lower end of the heel portion of the outer upper when the shoe is worn by the shoe wearer.
