Description

Technical Field

[0001] The invention relates to a shoe upper and a shoe comprising the shoe upper. Background Art

[0002] Conventionally, embroidery has been formed on a shoe upper in order to decorate the shoe upper to improve the design of the shoe upper or to control the physical properties of the shoe upper, such as tensile rigidity and abrasion resistance (see, for example, Patent Document 1).

[0003] The upper includes a cloth-like base material. The base material generally includes one or more layers including a surface and a back surface. As disclosed in Patent Document 1, conventional embroidery is formed by sewing thread onto the base material after manufacturing the base material. Hereinafter, the "thread" fixed to the base material is referred to as "thread material".

[0004] In order to expand the range of expression of the design of the shoe upper or partially change the physical properties of the shoe upper, it is ideal to be able to arbitrarily select the position of the linear material in the base material.

[0007] Patent Document 1: Japanese Patent Publication No. 2020-525088 Summary of the invention

[0008] Problems to be solved by the invention

[0009] However, in the conventional embroidery, when the base material is a single layer, the linear material must be arranged on the surface, back and inside of the layer of the base material, and when the base material is two or more layers, the linear material must be arranged in each layer of the base material. Therefore, in the conventional embroidery, there is a problem that the degree of freedom in selecting the position of the linear material in the base material is low.

[0010] The present invention has been made in view of the above, and an object of the present invention is to obtain a shoe upper capable of increasing the degree of freedom in selecting the position of a linear material in a base material.

[0011] Technical means of solving problems

[0012] In order to solve the above-mentioned problems and achieve the purpose, the upper of the present invention includes: a cloth-like substrate, including a layer, wherein the layer includes a surface and a back surface opposite to the surface; and a plurality of linear materials arranged on the substrate and formed independently of each other. The plurality of linear materials respectively include: a plurality of fixed portions, fixed to the layer, and separated from each other; and a plurality of non-fixed portions, located between adjacent fixed portions, and not fixed to the layer. The plurality of linear materials are alternately folded back along the in-plane direction of the substrate. The plurality of non-fixed portions connected via the fixed portions are exposed on at least one of the surface and the back surface of the layer, or are arranged inside the layer.

[0013] Effects of the Invention

[0014] The shoe upper of the present invention has the effect of increasing the degree of freedom in selecting the position of the linear material in the base material. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Hereinafter, embodiments of the shoe upper and the shoe of the present invention will be described in detail based on the accompanying drawings. In addition, the present invention is not limited to the embodiments described above. In the following description, the same reference numerals are used for the same parts, and repeated descriptions are omitted.

[0042] (Implementation Method 1)

[0043] Figure 1 FIG. 2 is a development diagram showing the upper 2 of the shoe 1 according to the first embodiment of the present invention. Figure 1 Each of the figures only illustrates the shoe 1 for the left foot. Since the shoe 1 has a bilaterally symmetrical structure between the left foot and the right foot, in this embodiment, only the shoe 1 for the left foot is described, and the description of the shoe 1 for the right foot is omitted. In the following description, the direction in which the shoe center axis C, which is a vertical line passing through the center of the shoe 1 when the shoe 1 is viewed from above, extends is referred to as the front-back direction, and the direction orthogonal to the front-back direction when the shoe 1 is viewed from above is referred to as the foot width direction.

[0044] In the following description, the direction from the heel toward the toe in the front-back midsole 1 is referred to as the front, and the direction from the toe toward the heel in the front-back midsole 1 is referred to as the rear.

[0045] In the following description, the median side of the foot in the anatomical position is referred to as the inner crura side, and the side opposite to the median side in the anatomical position is referred to as the outer crura side. That is, the side closer to the median in the anatomical position is referred to as the inner crura side, and the side farther from the median in the anatomical position is referred to as the outer crura side.

[0046] In the following description, unless otherwise specified, the up-down direction means a direction perpendicular to both the front-back direction and the foot width direction.

[0047] The shoe upper 2 includes a shoe front foot portion R1 covering the front foot portion of a wearer's foot of a standard body shape, a shoe midfoot portion R2 covering the middle foot portion of a wearer's foot of a standard body shape, and a shoe rear foot portion R3 covering the rear foot portion of a wearer's foot of a standard body shape. From the front of the shoe upper 2 toward the rear, the shoe front foot portion R1, the shoe midfoot portion R2, and the shoe rear foot portion R3 are connected in sequence.

[0048] A line along the foot width direction passing through a position approximately 30% to 40% of the front-to-back dimension of the upper 2 from the front end is set as the first boundary line S1, and a line along the foot width direction passing through a position approximately 73% to 83% of the front-to-back dimension of the upper 2 from the front end is set as the second boundary line S2. The first boundary line S1 is a line roughly along the metatarsophalangeal joint of a wearer with a standard body shape. The second boundary line S2 is a line roughly along the transverse tarsal joint of a wearer with a standard body shape. The forefoot portion R1 of the upper is the portion located in front of the first boundary line S1. The midfoot portion R2 of the upper is the portion located between the first boundary line S1 and the second boundary line S2. The rearfoot portion R3 of the upper is the portion located behind the second boundary line S2.

[0049] Figure 2 1 is a perspective view showing a shoe 1 according to Embodiment 1 of the present invention. The shoe 1 is preferably a running shoe, but may also be a shoe for other sports, a walking shoe, a mountain climbing shoe, etc. The shoe 1 includes an upper 2 and a sole 3 .

[0050] The upper 2 is located above the sole 3. The upper 2 includes a base material 20, a linear material arrangement area 21, a tongue 23, and a shoelace 24.

[0051] The base material 20 covers the part on the instep side of the wearer. A shoe opening 20a and a shoe throat 20b are formed on the upper part of the base material 20. The shoe opening 20a is an opening for the wearer's foot to enter the inside of the base material 20. The shoe throat 20b is an opening that is connected to the shoe opening 20a and extends forward from the shoe opening 20a. A plurality of rope threading parts 20c separated from each other in the front-to-back direction are provided on the side edges of both sides of the shoe throat 20b in the foot width direction. Figure 2 In the figure, only the threading portion 20c provided at the side edge of the shoe throat portion 20b on the outer foot side is shown. The threading portion 20c only needs to allow the shoelace 24 to pass through. The threading portion 20c is, for example, a through hole that penetrates the base material 20 along the thickness direction of the base material 20.

[0052] exist Figure 1 and Figure 2 In order to clarify the range of the linear material arrangement region 21, the linear material arrangement region 21 is marked with dotted lines. The linear material arrangement region 21 plays a role in decorating the upper 2 and partially changing the physical properties of the upper 2. The substrate 20 and the linear material arrangement region 21 are described in detail below.

[0053] The tongue 23 is a component for protecting the instep of the wearer. The tongue 23 covers the shoe throat 20b inside the base material 20. The tongue 23 is fixed to the base material 20 by sewing, welding, bonding or a combination of these. The base material 20 and the tongue 23 are, for example, a woven fabric in which a thread is curled into a chain shape and the chain-shaped parts are hooked to each other to form a cloth-like fabric, a woven fabric in which warp yarns and weft yarns are crossed at a certain angle to form a cloth-like fabric, and a woven fabric in which three or more twisted yarns are crossed with each other and run diagonally to form a cloth-like fabric. In particular, in the shoe 1 that requires breathability and lightness, the base material 20 and the tongue 23 are preferably a double-layer Raschel warp knitted fabric into which polyester yarn is knitted. In addition, the raw materials of the base material 20 and the tongue 23 are not limited to the raw materials illustrated.

[0054] The shoelace 24 is a band-shaped member that is alternately passed through the stringing part 20c provided on one side edge of the shoe throat 20b in the foot width direction and the stringing part 20c provided on the other side edge in the foot width direction.

[0055] In addition, in the present embodiment, the upper 2 including the tongue 23 and the shoelace 24 is described as an example, but the upper 2 may also be a sock structure in which a portion corresponding to the tongue 23 is integrated with the ankle portion of the base material 20. Moreover, the mechanism for making the base material 20 closely attached to the foot may be, for example, a hook and loop fastener instead of the shoelace 24. When the mechanism for making the base material 20 closely attached to the foot is a hook and loop fastener, the base material 20 is not formed with the string threading portion 20c.

[0056] The sole 3 is located below the upper 2. The sole 3 covers the sole of the wearer. The sole 3 is fixed to the base material 20 by stitching, welding, bonding or a combination of these. The sole 3 includes an outer sole 30 and a midsole 31. The lower surface of the outer sole 30 becomes a ground contact surface 30a provided on the ground. The midsole 31 is located on the upper surface of the outer sole 30 and has a cushioning property. In addition, the outer sole 30 can be integrated with the midsole 31. The outer sole 30 integrated with the midsole 31 is also called an "integrated sole".

[0057] Although not shown in the figure, the sole 3 includes an insole covering the lower opening of the base material 20. The insole is fixed to the upper surface of the midsole 31 by bonding or welding. The insole is fixed to the lower edge of the base material 20 by sewing. Although not shown in the figure, the shoe 1 may also include an insole. In the case where the shoe 1 includes an insole, the insole is provided inside the upper 2 and on the sole 3. In addition, the sole 3 may also be a structure in which the insole is omitted.

[0058] Next, refer to Figures 1 to 4 , the substrate 20 and the linear material configuration area 21 are further described in detail. Figure 3 It is along Figure 2 A cross-sectional view along line III-III is shown. Figure 4 is from Figure 3The arrow X shown is a diagram when observing the shoe upper 2.

[0059] like Figure 1 As shown, the substrate 20 includes a forefoot portion R1, a midfoot portion R2, and a rearfoot portion R3. Figure 2 As shown, the substrate 20 is disposed in the entire area of ​​the upper 2 except the tongue 23 and the shoelace 24. Figure 3 As shown, the substrate 20 is a cloth-like member including a layer 20d. The layer 20d includes a surface 20e and a back surface 20f facing opposite to the surface 20e.

[0060] The surface 20e is the surface facing the outside of the upper 2. In other words, the surface 20e is the surface located on the opposite side of the wearer's foot. The back side 20f is the surface facing the inside of the upper 2. In other words, the back side 20f is the surface located on the wearer's foot side. Figure 4 As shown in the figure, in this embodiment, the base material 20 is a knitted fabric formed by knitting a plurality of yarns 20g. The base material 20 includes a plurality of wales 20h extending along a first direction, and a plurality of rows 20i extending along a second direction orthogonal to the first direction. One of the first direction and the second direction coincides with the front-back direction, and the other of the first direction and the second direction coincides with the foot width direction.

[0061] like Figure 1 As shown, the linear material configuration area 21 is disposed in the forefoot portion R1 and the midfoot portion R2 of the upper of the substrate 20. In this embodiment, the linear material configuration area 21 is disposed in Figure 1 The position of the linear material configuration area 21 is not limited to the example shown in the figure. Figure 4 As shown, the linear material configuration area 21 is an area where a plurality of linear materials 22 are configured. The plurality of linear materials 22 are arranged on the base material 20 and are formed independently of each other. The plurality of linear materials 22 are arranged along the in-plane direction of the base material 20. The plurality of linear materials 22 are alternately folded back along the in-plane direction of the base material 20. The linear materials 22 have a variation range of 3 mm or more in the front-back direction or the foot width direction.

[0062] The yarn 20g of the linear material 22 and the base material 20 is, for example, a yarn formed by bundling a plurality of fibers, a yarn formed by linearizing a resin, a twisted yarn, etc. The material of the yarn 20g of the linear material 22 and the base material 20 is, for example, polyester, polyurethane-based thermoplastic elastomer, polyurethane, nylon, spandex elastic fiber, Kevlar (registered trademark), ultra-high molecular weight polyethylene, single covered yarn (Single Covered Yarn, SCY) or double covered yarn (Double Covered Yarn, DCY) formed by covering polyurethane, etc.

[0063] The material of part or all of the plurality of linear materials 22 may be the same as or different from the material of the yarn 20g of the base material 20. For example, the material of at least one of the plurality of linear materials 22 may be different from the material of the yarn 20g of the base material 20. The thickness of part or all of the plurality of linear materials 22 may be the same as or different from the thickness of the yarn 20g of the base material 20. For example, the thickness of at least one of the plurality of linear materials 22 may be different from the thickness of the yarn 20g of the base material 20.

[0064] The melting point of the material of at least one of the plurality of linear materials 22 is preferably lower than the melting point of the material of the substrate 20. For example, a part or all of the plurality of linear materials 22 may be yarns having a lower melting point than the yarn 20g of the substrate 20. Moreover, a part or all of the plurality of linear materials 22 may also be composite yarns containing fibers with different melting points. It is particularly desirable that a part or all of the plurality of linear materials 22 use a core-sheath structure in which a core material (fiber) having a high melting point is covered with a material having a low melting point. In this way, by heat-treating the linear material 22 at a temperature above the melting point of the material having a low melting point, the material having a low melting point is partially melted and solidified, thereby further improving the tensile rigidity of the upper 2.

[0065] The plurality of linear materials 22 respectively include a plurality of fixed portions 22a fixed to the layer 20d, and a plurality of non-fixed portions 22b not fixed to the layer 20d. The plurality of fixed portions 22a are arranged separately from each other. The fixed portion 22a is a portion that passes through the through portion 20j formed in the base material 20 and is wound around the yarn 20g. The through portion 20j is a circular hole. The through portion 20j is formed by winding a portion of adjacent loops in the base material 20. The plurality of non-fixed portions 22b are arranged separately from each other. The non-fixed portion 22b is located between adjacent fixed portions 22a.

[0066] The length L of the non-fixed portion 22b along the first direction may be appropriately set, and is preferably greater than 3 mm. The plurality of non-fixed portions 22b are respectively arranged across one wale of the substrate 20, and are arranged across two rows of the substrate 20. The number of rows of the substrate 20 spanned by the non-fixed portion 22b is greater than the number of wales of the substrate 20 spanned by the non-fixed portion 22b.

[0067] like Figure 3 As shown, the plurality of linear materials 22 are exposed on the surface 20e of the layer 20d, or are exposed on the back surface 20f of the layer 20d. Figure 3 , the figure shows a state where two separately formed linear materials 22 are arranged along the length direction of the linear materials 22. In the following description, when distinguishing the two linear materials 22, one of the linear materials 22 indicated by the dashed line is referred to as the first linear material 22A, and the other linear material 22 indicated by the dotted line is referred to as the second linear material 22B.

[0068] The plurality of non-fixed portions 22b of the first linear material 22A that are continuous via the fixed portion 22a are exposed on the surface 20e of the layer 20d. The non-fixed portion 22b of the first linear material 22A is exposed to the surface 20e of the substrate 20 that is located on the opposite side of the wearer's foot. The plurality of non-fixed portions 22b of the second linear material 22B that are continuous via the fixed portion 22a are exposed to the back surface 20f of the layer 20d. The non-fixed portion 22b of the second linear material 22B is exposed to the back surface 20f of the substrate 20 that is located on the wearer's foot side. The material of the first linear material 22A and the material of the second linear material 22B may be the same or different from each other. The thickness of the first linear material 22A and the thickness of the second linear material 22B may be the same or different from each other.

[0069] The upper 2 can be manufactured by using a dedicated machine such as a warp knitting machine, and the formation of the base material 20 and the formation of the linear material arrangement region 21 can be performed in a single process.

[0070] Next, the effects of the instep upper 2 and the shoe 1 according to the present embodiment will be described.

[0071] Figure 5 2 is a cross-sectional view of a shoe upper 110 of a shoe 100 according to a comparative example, and is a view showing a state where embroidery is formed on the shoe upper 110 having a layer 20d of a substrate 20. Figure 5 As shown, in the conventional embroidery, the non-fixed portion 22b of the thread-like material 22 is alternately exposed to the surface 20e and the back surface 20f of the layer 20d. That is, in the conventional embroidery, if the non-fixed portion 22b of the thread-like material 22 is exposed to the surface 20e of the layer 20d, the thread-like material 22 passes through the inside of the layer 20d, and the non-fixed portion 22b of the thread-like material 22 is also necessarily exposed to the back surface 20f of the layer 20d, and the thread-like material 22 is necessarily arranged on the surface 20e, the back surface 20f and the inside of the layer 20d of the base material 20.

[0072] In this embodiment, if Figure 3 As shown, the plurality of linear materials 22 respectively include a plurality of fixed portions 22a fixed to the layer 20d and arranged separately from each other, and a plurality of non-fixed portions 22b located between adjacent fixed portions 22a and not fixed to the layer 20d. In the present embodiment, the plurality of non-fixed portions 22b connected via the fixed portions 22a are exposed on the surface 20e arranged on the layer 20d, or are exposed on the back surface 20f arranged on the layer 20d. Through these structures, the plurality of non-fixed portions 22b of one linear material 22 can be continuously exposed to the surface 20e of the layer 20d, or the plurality of non-fixed portions 22b of one linear material 22 can be continuously exposed to the back surface 20f of the layer 20d, so that the degree of freedom of selection of the position of the linear material 22 in the base material 20 can be increased compared with the existing embroidery.

[0073] When a plurality of non-fixed portions 22b are exposed on the surface 20e of the layer 20d through the fixed portion 22a, any design can be freely given to the appearance of the upper 2. In addition, when a plurality of non-fixed portions 22b are exposed on the surface 20e of the layer 20d through the fixed portion 22a and the linear material 22 with high wear strength is used, the touch of the wearer's foot when the base material 20 is contacted can be maintained as the touch of the upper 2, and the wear strength and tensile rigidity of the outer surface of the upper 2 can be improved. When a plurality of non-fixed portions 22b are exposed on the back surface 20f of the layer 20d through the fixed portion 22a, the non-fixed portions 22b do not affect the design of the upper 2, or are unlikely to affect the design of the upper 2, so it is easy to maintain the design of the base material 20 as the design of the appearance of the upper 2. Furthermore, when a plurality of non-fixed portions 22b are exposed on the back surface 20f of the layer 20d through the fixed portion 22a and a linear material 22 with high wear strength is used, the wear strength and tensile rigidity of the inner surface of the upper 2 can be improved. Furthermore, when a plurality of non-fixed portions 22b are exposed on the back surface 20f of the layer 20d through the fixed portion 22a and a linear material 22 with a good skin touch is used, the touch of the wearer's foot when it contacts the linear material 22 can be improved. That is, in this embodiment, by being able to arbitrarily select the position of the linear material 22 in the base material 20, the expression range of the design of the upper 2 can be increased, and the physical properties of the upper 2 can be freely changed locally.

[0074] like Figure 5 As shown, in the conventional embroidery, when the non-fixed portion 22b can be observed from the surface 20e of the layer 20d, the non-fixed portion 22b is alternately exposed to the surface 20e and the back surface 20f of the layer 20d, so that the back surface 20f of the layer 20d has unevenness. The unevenness has an adverse effect on the touch of the foot, so it is necessary to attach a lining to the back surface 20f of the layer 20d, but this will increase the weight of the shoe 1. In this regard, in the present embodiment, as shown in FIG. Figure 3 As shown, when the non-fixed portion 22b can be observed from the surface 20e of the layer 20d, the plurality of non-fixed portions 22b are continuously exposed to the surface 20e of the layer 20d as in the first linear material 22A. Therefore, the back surface 20f of the layer 20d does not have unevenness, and the upper 2 with good foot touch can be provided without using a lining.

[0075] In this embodiment, it is possible to carry out the Figure 3 The formation of the substrate 20 and the formation of the linear material arrangement region 21 shown can reduce the number of manufacturing steps and the amount of waste of the upper 2, thereby achieving cost reduction and reduction of environmental load.

[0076] In order to pass Figure 4The wire material 22 shown improves the tensile rigidity of the upper 2, and needs to be arranged across two or more rows and wales of the base material 20. In the case of knitted fabrics, the maximum size of the rows and wales is about 3 mm, so it is ideal that the variation range of the wire material 22 is 3 mm or more as in the present embodiment.

[0077] In order to realize the diversity of the design and the diversity of the physical properties of the vamp 2 as in the present embodiment by using the prior art of forming embroidery on the vamp or welding yarn to the vamp, lining and adhesive are required. In the present embodiment, the diversity of the design and the diversity of the physical properties of the vamp 2 can be realized only by the linear material 22, and the lining and adhesive are not required, so the vamp 2 can be made lighter than the prior art.

[0078] In this embodiment, if Figure 3 As shown, the first linear material 22A exposed on the surface 20e of the layer 20d and the second linear material 22B exposed on the back surface 20f of the layer 20d are formed separately. Thus, the material, thickness, etc. of the first linear material 22A and the second linear material 22B can be changed to partially change the physical properties of the upper 2.

[0079] In the case of knitted fabrics, the size of the mesh is at most 3 mm. In this embodiment, Figure 4 Since the length L of the non-fixed portion 22 b shown exceeds 3 mm, it is possible to give the appearance of the upper 2 a design that cannot be expressed by knitted fabrics.

[0080] If Figure 4 If the thickness of at least one of the plurality of linear materials 22 shown is different from the thickness of the yarn 20g of the base material 20, physical properties such as abrasion resistance and tensile rigidity can be changed by the linear material 22 and the yarn 20g. Therefore, the physical properties of the portion of the upper 2 where the linear material 22 is arranged can be different from the physical properties of the portion of the upper 2 where the linear material 22 is not arranged.

[0081] If Figure 4 If the material of at least one of the plurality of linear materials 22 shown is different from the material of the yarn 20g of the base material 20, physical properties such as abrasion resistance and tensile rigidity can be changed by the linear material 22 and the yarn 20g. Therefore, the physical properties of the portion of the upper 2 where the linear material 22 is arranged can be different from the physical properties of the portion of the upper 2 where the linear material 22 is not arranged.

[0082] In this embodiment, if Figure 4 As shown, at least one of the plurality of non-fixed portions 22b is arranged across two or more rows of the base material 20. Thus, the appearance of the upper 2 can be given a design that cannot be expressed by knitted fabrics, and the tensile rigidity of the upper 2 in the row direction can be increased.

[0083] In this embodiment, if Figure 4 As shown, the number of rows of the base material 20 spanned by the non-fixed portion 22b is greater than the number of wales of the base material 20 spanned by the non-fixed portion 22b. Thus, for example, when the base material 20 is made of a material that is easily stretched and the linear material 22 is made of a material that is not easily stretched, it is possible to produce an upper 2 that is easily stretched in the wale direction (first direction) but not easily stretched in the row direction (second direction).

[0084] Next, a modification of the first embodiment will be described.

[0085] You can also Figure 3 The wire material 22 is divided into two parts. Figure 6 As shown, one linear member 22 is provided. Figure 6 2 is a cross-sectional view of a shoe upper 2 of a shoe 1 according to a first modification of the first embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III.

[0086] The linear material 22 is a single member including a first region 22c and a second region 22d. The first region 22c is a region where a plurality of non-fixed portions 22b are continuous via the fixed portion 22a and are only exposed on the surface 20e of the layer 20d. The second region 22d is a region where a plurality of non-fixed portions 22b are continuous via the fixed portion 22a and are only exposed on the back surface 20f of the layer 20d.

[0087] In this modification, the linear material 22 is a single member including the first region 22c and the second region 22d, so that the processing cost and environmental load can be reduced compared to the case where the portion corresponding to the first region 22c and the portion corresponding to the second region 22d are formed separately. In this modification, the linear material 22 is a single member including the first region 22c and the second region 22d, so that when the first region 22c is stretched, tension can be applied to the second region 22d, and the fit between the foot and the upper 2 can be improved. In addition, it is sufficient that at least one of the plurality of linear materials 22 is a single member including the first region 22c and the second region 22d.

[0088] In this embodiment, if Figure 3 As shown, a plurality of non-fixed portions 22b connected via the fixed portion 22a are exposed on the surface 20e of the layer 20d, or are exposed on the back surface 20f of the layer 20d, but may also be as shown in FIG. Figure 7 That is, the plurality of non-fixed portions 22b connected via the fixed portion 22a may be exposed on at least one of the front surface 20e and the back surface 20f of the layer 20d, or may be arranged inside the layer 20d. Figure 72 is a cross-sectional view of a shoe upper 2 of a shoe 1 according to a second variation of the first embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III.

[0089] like Figure 7 As shown, the structure of the first linear material 22A is the same as that of the first embodiment. In this modification, the second linear material 22B is arranged as a whole inside the layer 20d. Even in the case where the second linear material 22B is arranged as a whole inside the layer 20d, the second linear material 22B includes a plurality of fixed portions 22a and a plurality of non-fixed portions 22b. The fixed portion 22a is a portion knitted and woven into the yarn 20g inside the layer 20d. The non-fixed portion 22b is a portion that is not knitted and woven into the yarn 20g inside the layer 20d. In the second linear material 22B, a plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are arranged inside the layer 20d. The non-fixed portion 22b of the second linear material 22B is not exposed to the surface 20e and the back surface 20f of the substrate 20. In this modification, the formation of the substrate 20 and the formation of the linear material arrangement area 21 can be performed in one process, so the linear material 22 can be arranged inside the layer 20d of the substrate 20.

[0090] When the plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are arranged inside the layer 20d, although some non-fixed portions 22b can be observed when observing the appearance of the upper 2, it is easy to maintain a design similar to the base material 20 as the design of the appearance of the upper 2. In addition, when the plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are arranged inside the layer 20d, the touch of the wearer's foot when contacting the base material 20 can be maintained as the touch of the upper 2, and the tensile rigidity of the upper 2 can be improved. Depending on whether the positions of the plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are the surface 20e of the layer 20d, the back surface 20f of the layer 20d, or the inside of the layer 20d, the design of the base material 20 can be used directly or another design can be added to the base material 20, and the physical properties of the base material 20 can be used directly or another physical property can be added to the base material 20.

[0091] In addition, a structure in which the linear material 22 exposed on the surface 20e of the layer 20d and the linear material 22 disposed inside the layer 20d are integrally formed may be adopted. In the case of such a structure, the linear material 22 becomes a single member including a first region and a second region. The first region is a region in which a plurality of non-fixed portions 22b continuous via the fixed portion 22a are only exposed on the surface 20e of the layer 20d. The second region is a region in which a plurality of non-fixed portions 22b continuous via the fixed portion 22a are only disposed inside the layer 20d.

[0092] The linear material 22 may also be arranged at Figure 7The surface 20e of the layer 20d, the inside of the layer 20d, and the back side 20f of the layer 20d are shown. In this way, the non-fixed portion 22b is clearly observed in the region, the non-fixed portion 22b is slightly observed in the region, and the non-fixed portion 22b is not observed in the region. Therefore, a design having a height difference not only along the in-plane direction of the upper 2 but also along the thickness direction of the upper 2 can be expressed. That is, a three-dimensional design including the thickness direction of the upper 2 and the in-plane direction of the upper 2 can be created.

[0093] For example, when the layer 20d is a porous body such as a net, when the thickness of the layer 20d is thin, or when the layer 20d is transparent, there is a case where the non-fixed portion 22b arranged inside the layer 20d and the back side 20f of the layer 20d can be observed. In this case, the linear material 22 can also be arranged on the surface 20e of the layer 20d, the inside of the layer 20d, and the back side 20f of the layer 20d. In this way, the easy observation of the non-fixed portion 22b changes depending on the position of the non-fixed portion 22b in the substrate 20. Therefore, the linear material 22 can be vaguely observed, and a design with a height difference along the thickness direction of the upper 2 can be expressed.

[0094] The arrangement of the non-fixed portion 22b is not limited to Figure 4 The illustrated example may be modified as appropriate. For example, at least one of the plurality of non-fixed portions 22 b may be arranged across two or more wales of the base material 20 or two or more rows of the base material 20 .

[0095] For example, the configuration of the non-fixed portion 22b may be as follows Figure 8 Configuration shown. Figure 8 2 is a diagram showing a shoe upper 2 of a shoe 1 according to a third variation of the first embodiment of the present invention, Figure 3 The figure is equivalent to the figure when observing the vamp 2 along the arrow X shown. The plurality of non-fixed portions 22b are respectively arranged across five wales of the base material 20, and are arranged across one horizontal row of the base material 20. The number of wales of the base material 20 spanned by the non-fixed portion 22b is greater than the number of horizontal rows of the base material 20 spanned by the non-fixed portion 22b. In this modified example, it is possible to give the appearance of the vamp 2 a design that cannot be expressed by knitted fabrics. In this modified example, for example, when the base material 20 is made of a material that is easily stretched and the linear material 22 is made of a material that is not easily stretched, it is possible to produce a vamp 2 that is easily stretched along the horizontal row direction (second direction) but not easily stretched along the vertical row direction (first direction). In addition, the number of horizontal rows of the base material 20 spanned by the non-fixed portion 22b and the number of horizontal rows of the base material 20 spanned by the non-fixed portion 22b may be the same.

[0096] In the present embodiment, the base material 20 is a knitted fabric in which the plurality of yarns 20g are knitted, but may be a woven fabric in which the plurality of yarns 20g are woven, or a knitted fabric in which the plurality of yarns 20g are combined, for example.

[0097] (Implementation Method 2)

[0098] Reference Fig. 9 and Fig.10 A shoe 1A according to the second embodiment will be described. Fig. 9 2A is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a second embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III. Fig.10 2A of a shoe 1A according to a second embodiment of the present invention, Fig. 9 The figure corresponds to the figure when the shoe upper 2A is viewed along the arrow X. The shoe 1A of the second embodiment is different from the shoe 1 of the first embodiment in that the base material 20 has two or more layers 20d.

[0099] like Fig. 9 As shown, the substrate 20 is a cloth-like member including two or more layers 20d. In this embodiment, the number of layers 20d of the substrate 20 is three, but it can be changed appropriately. The substrate 20 includes a first layer 20k, a second layer 20m arranged with a gap between the first layer 20k and the second layer 20m, and a third layer 20n located between the first layer 20k and the second layer 20m.

[0100] The first layer 20k is located on the outermost side of the substrate 20. In other words, the first layer 20k is the layer 20d farthest from the wearer's foot in the substrate 20. The second layer 20m is located on the innermost side of the substrate 20. In other words, the second layer 20m is the layer 20d located closest to the wearer's foot in the substrate 20. The third layer 20n is located between the first layer 20k and the second layer 20m. The third layer 20n is a layer 20d that connects the first layer 20k and the second layer 20m and avoids contact between the first layer 20k and the second layer 20m. Although not shown in the figure, the third layer 20n includes a portion that connects the first layer 20k and the second layer 20m. In the present embodiment, the third layer 20n includes a space formed between the first layer 20k and the second layer 20m. The first layer 20k and the second layer 20m respectively include a surface 20e and a back surface 20f facing opposite to the surface 20e.

[0101] The surface 20e of the first layer 20k is the surface of the first layer 20k that faces the outside of the upper 2A. In other words, the surface 20e of the first layer 20k is the surface of the first layer 20k that is located on the opposite side of the wearer's foot. The back surface 20f of the first layer 20k is the surface of the first layer 20k that faces the inside of the upper 2A. In other words, in the first layer 20k, the back surface 20f of the first layer 20k is the surface located on the wearer's foot side.

[0102] The surface 20e of the second layer 20m is the surface of the second layer 20m that faces the inner side of the upper 2A. In other words, the surface 20e of the second layer 20m is the surface of the second layer 20m that is located on the wearer's foot side. The back surface 20f of the second layer 20m is the surface of the second layer 20m that faces the outer side of the upper 2A. In other words, the back surface 20f of the second layer 20m is the surface of the second layer 20m that is located on the opposite side of the wearer's foot.

[0103] In this embodiment, the surface of the layer 20d exposed to the inside or outside of the upper 2A is the surface 20e, and the surface of the layer 20d not exposed to both the inside and the outside of the upper 2A is the back surface 20f. Fig.10 As shown in the figure, in this embodiment, the base material 20 is a knitted fabric formed by knitting a plurality of yarns 20g. The base material 20 includes a plurality of wales 20h extending along a first direction, and a plurality of rows 20i extending along a second direction orthogonal to the first direction. One of the first direction and the second direction coincides with the front-back direction, and the other of the first direction and the second direction coincides with the foot width direction.

[0104] As in the first embodiment, the linear material arrangement region 21 is provided in the forefoot portion R1 and the midfoot portion R2 of the upper of the base material 20. Figure 1 The position of the linear material configuration area 21 is not limited to the example shown in the figure. Fig.10 As shown, the linear material configuration area 21 is an area where a plurality of linear materials 22 are configured. The plurality of linear materials 22 are arranged on the base material 20 and are formed independently of each other. The plurality of linear materials 22 are arranged along the in-plane direction of the base material 20. The plurality of linear materials 22 are alternately folded back along the in-plane direction of the base material 20. The linear materials 22 have a variation range of 3 mm or more in the front-back direction or the foot width direction.

[0105] The yarn 20g of the linear material 22 and the base material 20 is, for example, a yarn formed by bundling a plurality of fibers, a yarn formed by linearizing a resin, a twisted yarn, etc. The material of the yarn 20g of the linear material 22 and the base material 20 is, for example, polyester, polyurethane-based thermoplastic elastomer, polyurethane, nylon, spandex elastic fiber, Kevlar (registered trademark), ultra-high molecular weight polyethylene, single covered yarn (Single Covered Yarn, SCY) or double covered yarn (Double Covered Yarn, DCY) formed by covering polyurethane, etc.

[0106] The material of part or all of the plurality of linear materials 22 may be the same as or different from the material of the yarn 20g of the base material 20. For example, the material of at least one of the plurality of linear materials 22 may be different from the material of the yarn 20g of the base material 20. The thickness of part or all of the plurality of linear materials 22 may be the same as or different from the thickness of the yarn 20g of the base material 20. For example, the thickness of at least one of the plurality of linear materials 22 may be different from the thickness of the yarn 20g of the base material 20.

[0107] The melting point of the material of at least one of the plurality of linear materials 22 is preferably lower than the melting point of the material of the substrate 20. For example, a part or all of the plurality of linear materials 22 may be yarns having a lower melting point than the yarn 20g of the substrate 20. Moreover, a part or all of the plurality of linear materials 22 may also be composite yarns containing fibers with different melting points. It is particularly desirable that a part or all of the plurality of linear materials 22 use a core-sheath structure in which a core material (fiber) having a high melting point is covered with a material having a low melting point. In this way, by heat-treating the linear material 22 at a temperature above the melting point of the material having a low melting point, the material having a low melting point is partially melted and solidified, thereby further improving the tensile rigidity of the upper 2.

[0108] The plurality of linear materials 22 respectively include a plurality of fixed portions 22a fixed to at least one layer 20d, and a plurality of non-fixed portions 22b not fixed to the layer 20d. The plurality of fixed portions 22a are arranged separately from each other. The fixed portion 22a is a portion that passes through the through portion 20j formed in the base material 20 and is wound around the yarn 20g. The through portion 20j is a circular hole. The through portion 20j is formed by winding a portion of adjacent loops in the base material 20. The plurality of non-fixed portions 22b are arranged separately from each other. The non-fixed portion 22b is located between adjacent fixed portions 22a.

[0109] The length L of the non-fixed portion 22b along the first direction may be appropriately set, and is preferably greater than 3 mm. The plurality of non-fixed portions 22b are respectively arranged across one wale of the substrate 20, and are arranged across two rows of the substrate 20. The number of rows of the substrate 20 spanned by the non-fixed portion 22b is greater than the number of wales of the substrate 20 spanned by the non-fixed portion 22b.

[0110] like Fig. 9 As shown, a plurality of linear materials 22 are exposed on a surface 20e of at least one layer 20d. A plurality of non-fixed portions 22b connected via the fixed portions 22a are exposed on a surface 20e of the first layer 20k. The non-fixed portions 22b are exposed to the surface 20e of the first layer 20k, which is farthest from the wearer's foot in the base material 20.

[0111] The upper 2A can be manufactured by using a dedicated machine such as a warp knitting machine, and the formation of the base material 20 and the formation of the linear material arrangement region 21 can be performed in a single process.

[0112] Next, effects of the instep upper 2A and the shoe 1A according to the present embodiment will be described.

[0113] Fig.11 2 is a cross-sectional view showing a shoe upper 210 of a shoe 200 of a comparative example, and is a view showing a state where embroidery is formed on the shoe upper 210 having three layers of layer 20d of the substrate 20. Fig.11 As shown, in the conventional embroidery, the non-fixed portion 22b of the linear material 22 is alternately exposed to the surface 20e of the first layer 20k and the surface 20e of the second layer 20m. That is, in the conventional embroidery, if the non-fixed portion 22b of the linear material 22 is exposed to the surface 20e of the first layer 20k, the linear material 22 passes through the third layer 20n, and the non-fixed portion 22b of the linear material 22 is also necessarily exposed to the surface 20e of the second layer 20m, and the linear material 22 is necessarily arranged in each layer 20d of the base material 20.

[0114] In this embodiment, if Fig. 9 As shown, the plurality of linear materials 22 each include a plurality of fixed portions 22a that are fixed to at least one layer 20d and are arranged separately from each other, and a plurality of non-fixed portions 22b that are located between adjacent fixed portions 22a and are not fixed to the layer 20d. In this embodiment, the plurality of non-fixed portions 22b that are continuous via the fixed portions 22a are exposed on the surface 20e arranged on at least one layer 20d. With these structures, it is possible to Fig. 9 As shown, since the plurality of non-fixed portions 22b of one linear material 22 are continuously exposed on the surface 20e of the layer 20d, the degree of freedom in selecting the position of the linear material 22 in the base material 20 can be increased compared to conventional embroidery.

[0115] When the plurality of non-fixed portions 22b continuous via the fixed portion 22a are exposed on the surface 20e of the first layer 20k disposed farthest from the foot of the wearer in the base material 20, any design can be freely given to the appearance of the upper 2A. In addition, when the plurality of non-fixed portions 22b continuous via the fixed portion 22a are exposed on the surface 20e disposed on the first layer 20k and the linear material 22 with high wear strength is used, the touch of the wearer's foot when contacting the base material 20 can be maintained as the touch of the upper 2A, and the wear strength and tensile rigidity of the outer surface of the upper 2A can be improved.

[0116] like Fig.11 As shown, in the conventional embroidery, when the non-fixed portion 22b can be observed from the surface 20e of the first layer 20k, the surface 20e of the second layer 20m has unevenness because the non-fixed portion 22b is alternately exposed to the surface 20e of the first layer 20k and the surface 20e of the second layer 20m. The unevenness has an adverse effect on the touch of the foot, so it is necessary to attach a lining to the surface 20e of the second layer 20m, but this will increase the weight of the shoe 1A. In this regard, in the present embodiment, as shown in FIG. Fig. 9 As shown, when the non-fixed portion 22b can be observed from the surface 20e of the first layer 20k, the plurality of non-fixed portions 22b are continuously exposed to the surface 20e of the first layer 20k. Therefore, the surface 20e of the second layer 20m does not have unevenness, and the upper 2A with good foot touch can be provided without using a lining.

[0117] In this embodiment, it is possible to carry out the Fig. 9 The formation of the substrate 20 and the formation of the linear material arrangement region 21 shown can reduce the number of manufacturing steps and the amount of waste of the upper 2A, thereby achieving cost reduction and reduction of environmental load.

[0118] In order to pass Fig.10 The linear material 22 shown improves the tensile rigidity of the upper 2A, and needs to be arranged across two or more rows and wales constituting the base material 20. In the case of knitted fabrics, the maximum size of the rows and wales is about 3 mm, so it is ideal that the variation range of the linear material 22 is 3 mm or more as in the present embodiment.

[0119] In order to realize the diversity of design and physical properties of the vamp 2A as in the present embodiment by using the prior art of forming embroidery on the vamp or fusing yarn to the vamp, lining and adhesive are required. In the present embodiment, the diversity of design and physical properties of the vamp 2A can be realized only by the linear material 22, and the lining and adhesive are not required, so the vamp 2A can be made lighter than the prior art.

[0120] In the case of knitted fabrics, the size of the mesh is at most 3 mm. In this embodiment, Fig.10 Since the length L of the non-fixed portion 22b shown exceeds 3 mm, it is possible to give the appearance of the upper 2A a design that cannot be expressed by knitted fabrics.

[0121] If Fig.10 If the thickness of at least one of the plurality of linear materials 22 shown is different from the thickness of the yarn 20g of the base material 20, physical properties such as abrasion resistance and tensile rigidity can be changed by the linear material 22 and the yarn 20g. Therefore, the physical properties of the portion of the upper 2A where the linear material 22 is arranged can be different from the physical properties of the portion of the upper 2A where the linear material 22 is not arranged.

[0122] If Fig.10 If the material of at least one of the plurality of linear materials 22 shown is different from the material of the yarn 20g of the base material 20, physical properties such as abrasion resistance and tensile rigidity can be changed by the linear material 22 and the yarn 20g. Therefore, the physical properties of the portion of the upper 2A where the linear material 22 is arranged can be different from the physical properties of the portion of the upper 2A where the linear material 22 is not arranged.

[0123] In this embodiment, if Fig.10 As shown, at least one of the plurality of non-fixed portions 22b is arranged across two or more rows of the base material 20. Thus, the appearance of the upper 2A can be given a design that cannot be expressed by knitted fabrics, and the tensile rigidity of the upper 2 in the row direction can be increased.

[0124] In this embodiment, if Fig.10 As shown, the number of rows of the base material 20 spanned by the non-fixed portion 22b is greater than the number of wales of the base material 20 spanned by the non-fixed portion 22b. Thus, for example, when the base material 20 is made of a material that is easily stretched and the linear material 22 is made of a material that is not easily stretched, it is possible to produce an upper 2A that is easily stretched in the wale direction (first direction) but not easily stretched in the row direction (second direction).

[0125] Next, a modification example of the second embodiment will be described.

[0126] like Fig.12 As shown, the number of layers 20d of the substrate 20 may also be two. Fig.12 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a first modification of the second embodiment of the present invention, Figure 2The base material 20 includes a first layer 20k and a second layer 20m disposed in contact with the first layer 20k. The first layer 20k and the second layer 20m overlap each other along the thickness direction of the upper 2A. The back surface 20f of the first layer 20k and the back surface 20f of the second layer 20m are in contact with each other. A plurality of non-fixed portions 22b connected via the fixed portion 22a are exposed on the surface 20e disposed on the first layer 20k. This modified example can also achieve the same effect as the above-described embodiment.

[0127] The position of the non-fixed portion 22b is not limited to Fig. 9 The example shown in the figure can also be changed appropriately. For example, the position of the non-fixed portion 22b can also be as follows Fig.13 Position shown. Fig.13 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a second modification of the second embodiment of the present invention, Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III. Fig.13 The plurality of non-fixed portions 22b shown to be continuous via the fixed portion 22a are arranged inside the layer 20d.

[0128] In this modification, the entirety of the linear material 22 is arranged inside the layer 20d. In the case where the entirety of the linear material 22 is arranged inside the layer 20d, the linear material 22 also includes a plurality of fixed portions 22a and a plurality of non-fixed portions 22b. The fixed portion 22a is a portion knitted and woven into the yarn 20g inside the layer 20d. The non-fixed portion 22b is a portion that is not knitted and woven into the yarn 20g inside the layer 20d. A plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are arranged inside the first layer 20k. The non-fixed portion 22b is not exposed to the surface 20e and the back surface 20f of each layer 20d. In this modification, the formation of the substrate 20 and the formation of the linear material configuration area 21 can be performed in a single process, so that the linear material 22 can be arranged inside the layer 20d of the substrate 20.

[0129] As in this modification, when a plurality of non-fixed portions 22b are arranged inside the first layer 20k via the fixed portion 22a, although some non-fixed portions 22b can be observed when observing the appearance of the upper 2A, it is easy to maintain a design similar to the base material 20 as the design of the appearance of the upper 2A. In addition, when a plurality of non-fixed portions 22b are arranged inside the first layer 20k via the fixed portion 22a, the tensile rigidity of the first layer 20k of the upper 2A can be increased.

[0130] The position of the non-fixed portion 22b may also be as follows Fig.14 Position shown. Fig.14 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a third variation of the second embodiment of the present invention. Figure 2The figure shown is equivalent to the cross-sectional view along line III-III. Fig.14 The plurality of non-fixed portions 22b shown in the figure are connected to the fixed portion 22a and are exposed on the surface 20e of the first layer 20k or are arranged inside the first layer 20k. Fig.14 , the figure shows a state where two separately formed linear materials 22 are arranged along the length direction of the linear materials 22. In the following description, when distinguishing the two linear materials 22, one of the linear materials 22 indicated by the dashed line is referred to as the first linear material 22A, and the other linear material 22 indicated by the dotted line is referred to as the second linear material 22B.

[0131] The plurality of non-fixed portions 22b that are continuous via the fixed portion 22a in the first linear material 22A are exposed and arranged on the surface 20e of the first layer 20k. The plurality of non-fixed portions 22b that are continuous via the fixed portion 22a in the second linear material 22B are arranged inside the first layer 20k. The material of the first linear material 22A and the material of the second linear material 22B may be the same or different. The thickness of the first linear material 22A and the thickness of the second linear material 22B may be the same or different.

[0132] In this modification, the same effect as any one of the above-mentioned embodiments and modifications can be achieved. Moreover, by separately forming the first linear material 22A exposed on the surface 20e of the first layer 20k and the second linear material 22B disposed inside the first layer 20k, the material, thickness, etc. of the first linear material 22A and the second linear material 22B can be changed, thereby partially changing the physical properties of the upper 2A.

[0133] In addition, the wire-shaped material 22 divided into two may be set as one wire-shaped material 22. That is, at least one of the plurality of wire-shaped materials 22 may be a single member including a region where a plurality of non-fixed portions 22b connected via the fixed portion 22a are only exposed and arranged on the surface 20e of the first layer 20k, and a region where a plurality of non-fixed portions 22b connected via the fixed portion 22a are only arranged inside the first layer 20k. In this way, processing costs and environmental loads can be reduced.

[0134] The position of the non-fixed portion 22b may also be as follows Fig.15 Position shown. Fig.15 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a fourth variation of the second embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III. Fig.15 The plurality of non-fixed portions 22b that are continuous via the fixed portions 22a are exposed on the surface 20e of the second layer 20m.

[0135] As in this modification, when a plurality of non-fixed portions 22b are exposed on the surface 20e of the second layer 20m through the fixed portion 22a, the non-fixed portions 22b will not affect the design of the upper 2A, or will not easily affect the design of the upper 2A. Therefore, it is easy to maintain the design of the first layer 20k of the base material 20 as the design of the appearance of the upper 2A. Moreover, when a plurality of non-fixed portions 22b are exposed on the surface 20e of the second layer 20m through the fixed portion 22a and a linear material 22 with high wear strength is used, the wear strength and tensile rigidity of the inner surface of the upper 2A can be improved. Moreover, when a plurality of non-fixed portions 22b are exposed on the surface 20e of the second layer 20m through the fixed portion 22a and a linear material 22 with a good skin touch is used, the touch of the wearer's foot when contacting the linear material 22 can be improved.

[0136] The position of the non-fixed portion 22b may also be as follows Fig.16 Position shown. Fig.16 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a fifth variation of the second embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III. Fig.16 The plurality of non-fixed portions 22b shown to be continuous via the fixed portion 22a are arranged inside the second layer 20m.

[0137] As in this modification, when a plurality of non-fixed portions 22b are arranged inside the second layer 20m via the fixed portion 22a, the non-fixed portions 22b do not affect the design of the upper 2A, or are unlikely to affect the design of the upper 2A. Therefore, it is easy to maintain the design of the first layer 20k of the base material 20 as the design of the appearance of the upper 2A. In addition, when a plurality of non-fixed portions 22b are arranged inside the second layer 20m via the fixed portion 22a and the linear material 22 is used, the touch of the wearer's foot when contacting the base material 20 can be maintained as the touch of the upper 2A, and the tensile rigidity of the second layer 20m of the upper 2A can be improved.

[0138] The position of the non-fixed portion 22b may also be as follows Fig.17 Position shown. Fig.17 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a sixth variation of the second embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III. Fig.17 The plurality of non-fixed portions 22b shown as being continuous via the fixed portion 22a are exposed on the surface 20e of the second layer 20m or are disposed inside the second layer 20m. Fig.17, the figure shows a state where two separately formed linear materials 22 are arranged along the length direction of the linear materials 22. In the following description, when distinguishing the two linear materials 22, one of the linear materials 22 indicated by the dashed line is referred to as the first linear material 22A, and the other linear material 22 indicated by the dotted line is referred to as the second linear material 22B.

[0139] The plurality of non-fixed portions 22b that are continuous via the fixed portion 22a in the first linear material 22A are exposed on the surface 20e of the second layer 20m. The plurality of non-fixed portions 22b that are continuous via the fixed portion 22a in the second linear material 22B are arranged inside the second layer 20m. The material of the first linear material 22A and the material of the second linear material 22B may be the same as or different from each other. The thickness of the first linear material 22A and the thickness of the second linear material 22B may be the same as or different from each other. In this modification, the same effect as any of the above-described embodiments and modifications can be achieved.

[0140] In addition, the wire material 22 divided into two may be set as one wire material 22. That is, at least one of the plurality of wire materials 22 may be a single member including a region where a plurality of non-fixed portions 22b connected via the fixed portion 22a are exposed only on the surface 20e of the second layer 20m, and a region where a plurality of non-fixed portions 22b connected via the fixed portion 22a are connected inside the second layer 20m. In this way, processing costs and environmental loads can be reduced.

[0141] The position of the non-fixed portion 22b may also be as follows Fig.18 Position shown. Fig.18 2 is a cross-sectional view showing a shoe upper 2A of a shoe 1A according to a seventh variation of the second embodiment of the present invention. Figure 2 The figure shown is equivalent to the cross-sectional view along line III-III. Fig.18 The plurality of non-fixed portions 22b shown in the figure are connected to the fixed portion 22a and are exposed on the surface 20e of the first layer 20k or are arranged inside the third layer 20n. Fig.18 , the figure shows a state where two separately formed linear materials 22 are arranged along the length direction of the linear materials 22. In the following description, when distinguishing between the two linear materials 22, one of the linear materials 22 indicated by the dashed line is referred to as the first linear material 22A, and the other linear material 22 indicated by the solid line is referred to as the second linear material 22B.

[0142] The plurality of non-fixed portions 22b that are continuous via the fixed portion 22a in the first linear material 22A are exposed on the surface 20e arranged on the first layer 20k. The entire second linear material 22B is arranged inside the third layer 20n. In the case where the entire second linear material 22B is arranged inside the third layer 20n, although not shown in the figure, the second linear material 22B also includes a plurality of fixed portions 22a and a plurality of non-fixed portions 22b. Although not shown in the figure, the fixed portion 22a of the second linear material 22B is a portion knitted into the portion of the third layer 20n that connects the first layer 20k and the second layer 20m. The non-fixed portion 22b is a portion knitted into the yarn 20g inside the third layer 20n. The plurality of non-fixed portions 22b that are continuous via the fixed portion 22a in the second linear material 22B are arranged inside the third layer 20n. The material of the first linear material 22A and the material of the second linear material 22B may be the same as or different from each other. The thickness of the first linear material 22A and the thickness of the second linear material 22B may be the same as or different from each other.

[0143] As in this modification, when a plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are arranged inside the third layer 20n, the non-fixed portions 22b do not affect the design of the upper 2A, or are unlikely to affect the design of the upper 2A. Therefore, at the portion where the second linear material 22B is arranged in the base material 20, it is easy to maintain the design of the first layer 20k of the base material 20 as the design of the appearance of the upper 2A. Thus, without changing the appearance of the base material 20, the bending rigidity of the upper 2A can be partially improved. Moreover, when a plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are arranged inside the third layer 20n, it is possible to maintain the touch of the wearer's foot when it contacts the base material 20 as the touch of the upper 2A, and improve the tensile rigidity of the third layer 20n of the upper 2A.

[0144] In addition, the wire material 22 divided into two may be set as one wire material 22. That is, at least one of the plurality of wire materials 22 may be a single member including a plurality of non-fixed portions 22b continuous via the fixed portion 22a only exposed in the region arranged on the surface 20e of the first layer 20k, and a plurality of non-fixed portions 22b continuous via the fixed portion 22a only arranged in the region inside the third layer 20n.

In this modification, the same effect as any of the above-mentioned embodiments and modifications can be exerted.

[0168] In addition, the three-piece linear material 22 may be provided as one linear material 22. That is, at least one of the plurality of linear materials 22 may be a single member including a plurality of non-fixed portions 22b continuous via the fixed portion 22a only exposed in the region of the surface 20e of the second layer 20m, a plurality of non-fixed portions 22b continuous via the fixed portion 22a only arranged in the region inside the first layer 20k, and a plurality of non-fixed portions 22b continuous via the fixed portion 22a only arranged in the region inside the third layer 20n. In this way, processing costs and environmental loads can be reduced.

[0169] As described above, in this embodiment, the plurality of non-fixed portions 22b that are continuous via the fixed portion 22a only need to be exposed on the surface 20e of at least one layer 20d or inside the at least one layer 20d. Depending on whether the positions of the plurality of non-fixed portions 22b that are continuous via the fixed portion 22a are the surface 20e of at least one layer 20d or inside the at least one layer 20d, the design of the base material 20 can be directly used or other designs can be added to the base material 20, and the physical properties of the base material 20 can be directly used or other physical properties can be added to the base material 20. That is, in this embodiment, by being able to arbitrarily select the position of the linear material 22 in the base material 20, the expression range of the design of the upper 2A can be increased, and the physical properties of the upper 2A can be partially freely changed.

[0170] The linear material 22 may also be arranged at Fig.25 At least one of the surface 20e of the first layer 20k, the interior of the first layer 20k, the interior of the third layer 20n, the interior of the second layer 20m, and the surface 20e of the second layer 20m is shown. In this way, it is divided into an area where the non-fixed portion 22b can be clearly observed, an area where some non-fixed portions 22b can be observed, and an area where the non-fixed portions 22b cannot be observed. Therefore, it is possible to express a design in which there is a height difference not only along the in-plane direction of the upper 2A but also along the thickness direction of the upper 2A. That is, it is possible to create a three-dimensional design including the thickness direction of the upper 2A and the in-plane direction of the upper 2A.

[0171] For example, when the layer 20d is a porous body such as a net, when the thickness of the layer 20d is thin, or when the layer 20d is transparent, there is a case where the non-fixed portion 22b arranged inside the third layer 20n, inside the second layer 20m, and the surface 20e of the second layer 20m can be observed. In this case, the linear material 22 can also be arranged on at least one of the surface 20e of the first layer 20k, the inside of the first layer 20k, and the inside of the third layer 20n, the inside of the second layer 20m, and the surface 20e of the second layer 20m. In this way, the easy observation of the non-fixed portion 22b changes according to the position of the non-fixed portion 22b in the substrate 20. Therefore, the linear material 22 can be vaguely observed, and a design with a height difference along the thickness direction of the upper 2A can be expressed.

[0172] The arrangement of the non-fixed portion 22b is not limited to Fig.10 The illustrated example may be modified as appropriate. For example, at least one of the plurality of non-fixed portions 22 b may be arranged across two or more wales of the base material 20 or two or more rows of the base material 20 .

[0173] For example, the number of wales of the base material 20 spanned by the non-fixed portion 22b may be greater than the number of wales of the base material 20 spanned by the non-fixed portion 22b. In this way, the appearance of the upper 2A can be given a design that cannot be expressed by knitted fabrics. For example, when the base material 20 is made of a material that is easily stretched and the linear material 22 is made of a material that is not easily stretched, it is possible to produce an upper 2A that is easily stretched along the wale direction (second direction) but not easily stretched along the wale direction (first direction). In addition, the number of wales of the base material 20 spanned by the non-fixed portion 22b and the number of wales of the base material 20 spanned by the non-fixed portion 22b may be the same.

[0174] In the present embodiment, the base material 20 is a knitted fabric in which the plurality of yarns 20g are knitted, but may be a woven fabric in which the plurality of yarns 20g are woven, or a knitted fabric in which the plurality of yarns 20g are combined, for example.
