Benefits of technology

The present invention introduces a shoe with a sponge member in the heel area to improve the fitting of the shoe. This is done by attaching markers to the foot in a specific pattern and using images to analyze the markers. The sponge member is placed in the areas where the shape of the foot is hollowed and does not change significantly, directly below the medial ankle and also immediately below the lateral ankle, to enhance the fit.

Problems solved by technology

Therefore, in the prior art, the conformity of the upper to the foot (the fitting property) has not been satisfactory.

embodiment 1

FIGS. 4 to 5D Show Embodiment 1

[0070]As shown in FIG. 4, the upper 1 includes the inner skin 11 placed on the wear's skin side, and the outer skin 12 placed on the opposite side from the inner skin 11. The sponge member 3 is housed between the inner skin 11 and the outer skin 12 in the heel portion 10.

[0071]Note that although the sponge member 3 undergoes substantial compressive deformation, or the like, when manufacturing the shoe, FIG. 4 merely shows the conceptual placement of the sponge member 3. Reference numeral 6 denotes an insole.

[0072]The inner skin 11 may be a mesh material, or the like, as well as a woven material or a knit material having desirable stretchability and air-permeability. On the other hand, the outer skin 12 may be a mesh material, or the like, as well as a plate or tape material made of a synthetic leather or a non-foamed synthetic resin having a desirable shape retention.

[0073]Note that each of the inner skin 11 and the outer skin 12 may include a single l...

embodiment 3

FIGS. 7A to 7D Show Embodiment 3

[0092]In the present embodiment, the third sponge plate 33 is absent. In such a case, the thickness of the first and second sponge plates 31 and 32 is preferably made greater than that in Embodiments 1 and 2.

[0093]In various embodiments, the thickness of the sponge plates 31 and 32 is preferably about 5 to 15 mm, and more preferably about 7 to 12 mm.

[0094]As shown in FIG. 7A, in Embodiment 3, the second sponge plate 32 has a narrowed portion 38 that is narrowed downwardly in the area of the center line CL. The narrowed portion 38, in cooperation with the narrowed portion 36, will further unlikely causes compression on the Achilles tendon.

[0095]As shown in FIGS. 7A, 7C and 7D, the second sponge plate 32 has a significantly larger area on the medial side portion 34 than on the lateral side portion 35. The second sponge plate 32 extends to a point anterior to the posterior end Ab of the medial ankle A1 on the medial side portion 34 of FIG. 7C, and the se...

embodiment 4

FIGS. 8A to 8D Show Embodiment 4

[0096]In this example, the medial side portion 34 and the lateral side portion 35 have shapes that are generally in line symmetry with each other about the center line CL.

[0097]In the present embodiment, the medial side portion 34 of the first sponge plate 31 covers at least a portion of the lower edge Ce of the calcaneal bone Ca directly below the talus Ta. On the other hand, the lateral side portion 35 of the first sponge plate 31 covers an area of the calcaneal bone Ca directly above the point O, wherein the point O is a bisector between the lower end of the lateral ankle A0 and the lower edge Ce of the calcaneal bone Ca.

[0098]The second sponge plate 32 of FIG. 8A includes, at its opposite ends, protruding portions 39 and 39 that coincide with the upper edge line of the first sponge plate 31. The protruding portions 39 will be helpful in positioning the first sponge plate 31 and the second sponge plate 32 with each other.

[0099]The sponge member 3 o...

Abstract

An upper includes an inner skin placed on a wear's skin side, and an outer skin placed on an opposite side from the inner skin, wherein a sponge member is housed between the inner skin and the outer skin in a heel portion; the sponge member includes a medial side portion covering a medial side of a calcaneal bone, and a lateral side portion covering a lateral side of the calcaneal bone; and in a developed view where the sponge member is unfolded into a planar shape, a height of a lateral first centroid of a portion corresponding to the lateral side portion is set to be higher than a height of a medial first centroid of a portion corresponding to the medial side portion.

Description

TECHNICAL FIELD[0001]The present invention relates to an upper having a sponge member in a heel portion.BACKGROUND ART[0002]Shoes having a sponge member in the heel portion in order to improve the fit of the heel portion of the upper are well known in the art.CITATION LISTPatent Literature[0003]First Patent Document: JP2011-041590 A (abstract)[0004]Second Patent Document: JP2010-022791 A (abstract)SUMMARY OF INVENTION[0005]There have been no researches in the prior art on the sponge member conducted while sufficiently taking into consideration the change in the shape of the foot. Therefore, in the prior art, the conformity of the upper to the foot (the fitting property) has not been satisfactory.[0006]It is therefore an object of the present invention to provide an upper having a sponge member in a heel portion, with which it is possible to improve the fitting property of the upper.Principle of the Invention[0007]Prior to the description of the configuration of the present invention...
