AI Technical Summary

Benefits of technology

The invention provides a shoe with a specific design at the mid-foot area. The inner upper portion of the shoe has a small space relative to the outer upper portion, which allows for a snug fit and improved comfort. The inner upper portion also stretches to provide a pressing force to the mid-foot region, which helps to reduce pain and make the shoe fit better. The outer upper portion, on the other hand, provides better support and comfort to the mid-foot region. This design feature helps to make the shoe fit better and more comfortably.

Problems solved by technology

Such a large difference in level restricts a smooth bending at the time of bending of the foot, impedes adhesive and fitting properties relative to the foot, and gives discomfort to a sensitive forepart region.

first alternative embodiment

[0116]In the above-mentioned embodiment, an example was shown in which the rearmost end 20Bb of the stretch portion 20B is disposed at a position closer to the front end of the heel part H (see FIGS. 4, 5, 10-13), but the application of the present invention is not restricted to such an example. The rearmost end 20Bb of the stretch portion 20B may be disposed at a position closer to the rear end of the heel part H, for example, at the bottom portion of the calcaneus CA (see FIGS. 12, 13).

second alternative embodiment

[0117]In the above-mentioned embodiment, an example was shown in which the clearances e1, e2 are respectively formed between the medial-side and lateral-side parts 211, 212 of the outer upper portion 21 and the inner upper potion 20 (see FIGS. 8, 9, 8A, 9A), but only either one of these clearances e1, e2 may be formed.

third alternative embodiment

[0118]In the above-mentioned embodiment, an example was shown in which the perimeter 201L of the external surface 20s of the inner upper portion 20 is smaller than the perimeter 211L of the internal surface 211S of the medial-side part 211 of the outer upper portion 21, and the perimeter 202L of the external surface 20s of the inner upper portion 20 is smaller than the perimeter 212L of the internal surface 212S of the lateral-side part 212 of the outer upper portion 21 (see FIGS. 8, 9, 8A, 9A), but the application of the present invention is not limited to such an example. Such a size relation of the perimeters of the inner upper portion 20 and the outer upper portion 21 may be satisfied at only either one of the medial-side part 211 and the lateral-side part 212 of the outer upper portion 21.

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.

Description

TECHNICAL FIELD[0001]The present invention relates generally to a shoe upper structure for a shoe that can improve fitting and supporting properties not only at a forefoot region but also at a midfoot region of a foot of a shoe wearer, to a shoe having the upper structure, and to a method for manufacturing the shoe.BACKGROUND ART[0002]U.S. Pat. No. 4,438,574 discloses a sports shoe (10) that has an upper structure comprising a stretchable inner layer (40) and a non-stretchable outer layer (42) at a forepart section (see lines 32-39 of column 4 and FIGS. 1-4). Here, the forepart section designates a toe portion of a foot (see lines 60-63 of column 3).[0003]The above-mentioned US Pat. describes that a limited amount of stretch of the stretchable inner layer (40) causes the inner layer (40) to conform to the shape of the forefoot section of the foot thus obtaining a proper fit (see lines 11-13 of column 3) and the non-stretchable outer layer (42) can prevent the inner layer (90) from s...
