Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to shoes and methods of manufacturing shoes. [Background technology]

[0002] International Publication No. 2015 / 151195 (Patent Document 1) discloses a conventional shoe, the upper of which includes a sock, outer and inner eyelets, at least one outer reinforcement member, and at least one inner reinforcement member.

[0003] The outer and inner eyelets are disposed on the outer and inner edges of the sock opening, respectively. The outer and inner eyelets are less likely to stretch than the material forming the sock. The outer and inner eyelets have a plurality of holes through which the shoelaces pass. The eyelets may be formed from a material such as tape or artificial leather, or a combination of two or more of these materials. The plurality of holes through which the shoelaces pass may be small circular holes formed in the artificial leather or the like, or may be loop material sewn to the artificial leather or the like.

[0004] The outer reinforcement is less stretchable than the sock-forming elements and extends from the outer eyelet to the sole or heel counter. The inner reinforcement is less stretchable than the sock-forming elements and extends from the inner eyelet to the sole or heel counter. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] International Publication No. 2015 / 151195 Summary of the Invention [Problem to be solved by the invention]

[0006] In the shoe disclosed in Patent Document 1, in order to provide multiple holes for the shoelaces, it is necessary to either form multiple holes directly in the eyelets or to prepare a separate member from the eyelets. Furthermore, in order to provide the multiple holes, it is necessary to mold the reinforcing member (reinforcing material) into the desired shape. In this way, in shoes in which the reinforcing member is disposed on the outer surface of the upper body, there is room for improving production efficiency by simplifying the processing of the reinforcing member and the structure of the reinforcing member itself.

[0007] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a shoe and a shoe manufacturing method with improved production efficiency for shoes in which reinforcing members are arranged on the surface of the upper body. [Means for solving the problem]

[0008] A shoe according to the present disclosure includes a sole and an upper. The upper is located above the sole and has an opening for inserting a wearer's foot when worn, and a lacing area located in front of the opening. The upper includes an upper body and a tape-like tape member. The upper body, together with the sole, can accommodate the wearer's foot. The tape member is sewn to the outer surface of the upper body. The tape member is more rigid than the upper body. The tape member has a first band-shaped portion, a folded portion, and a second band-shaped portion. The first band-shaped portion is located in the lacing area and extends along the front-to-rear direction of the upper. The folded portion is continuous with at least one of the front and rear ends of the first band-shaped portion. The folded portion is formed by folding the tape member downward when viewed from the first band-shaped portion. The second band-shaped portion extends downward from the folded portion. The first band-shaped portion is sewn to the upper body so as to form a plurality of gaps between the first band-shaped portion and the upper body for threading shoelaces through.

[0009] A method for manufacturing a shoe according to the present disclosure includes the steps of preparing a sole, manufacturing an upper having an opening for inserting a wearer's foot when worn and a lacing area located in front of the opening, and joining the upper to the upper side of the sole. The upper manufacturing step includes the steps of preparing an upper body capable of accommodating the wearer's foot together with the sole, folding a tape member having a higher rigidity than the upper body at a folding location to form a folded portion, sewing a first band-shaped portion of the tape member, which is one side of the folded portion, to the outer surface of the upper body so that it is located in the lacing area and extends along the front-to-rear direction of the upper, and attaching a second band-shaped portion of the tape member, which is the other side of the folded portion, to the outer surface of the upper body so that it extends downward from the folded portion. The first band-shaped portion is sewn to the upper body so that multiple gaps for threading shoelaces are formed between the first band-shaped portion and the upper body. [Effects of the Invention]

[0010] According to the present disclosure, first and second bands for reinforcing the upper body are provided by folding a tape member. This simplifies the processing of the reinforcing members and the configuration of the members themselves. Furthermore, multiple gaps for threading shoelaces are formed by sewing the first band to the upper body. This simplifies the processing of the first band and the configuration for threading shoelaces themselves. Therefore, the present disclosure can provide a shoe and a shoe manufacturing method in which reinforcing members are arranged on the surface of the upper body and which has improved production efficiency.

[0016] (Embodiment 1) [shoes] FIG. 1 is a perspective view of a shoe according to a first embodiment of the present disclosure, shown from the outer side of the foot. FIG. 2 is a perspective view of a shoe according to the first embodiment of the present disclosure, shown from the inner side of the foot. FIG. 3 is a side view of a shoe according to the first embodiment of the present disclosure, shown from the outer side of the foot. FIG. 4 is a side view of a shoe according to the first embodiment of the present disclosure, shown from the inner side of the foot. FIG. 5 is a plan view of a shoe according to the first embodiment of the present disclosure. As shown in FIGS. 1 to 5, a shoe 1 according to the first embodiment of the present disclosure includes a sole 5 and an upper 10.

[0017] The sole 5 has a ground contact surface 5G and a peripheral side surface 5S. The peripheral side surface 5S extends upward from the peripheral edge of the ground contact surface 5G.

[0018] Although there are no particular limitations on the material that constitutes the sole 5, it is preferable that the entire sole 5 be made of a single polymer composition, for example, from the viewpoint of improving production efficiency. More preferably, from the viewpoint of improving cushioning performance, the polymer composition contains a component that is at least either a homopolymer containing farnesene as a constituent unit or a copolymer containing farnesene as a constituent unit.

[0019] The upper 10 is located above the sole 5. The upper 10 has an opening 10A and a lacing area 10L. The opening 10A is formed so that the wearer's foot can be inserted when wearing the shoe. The lacing area 10L is located in front of the opening 10A. The components arranged in the lacing area 10L will be described later.

[0020] The upper 10 has an upper body 100 , at least one tape member 200 , and a plurality of stitched portions 300 .

[0021] First, a description will be given of the upper body 100. The upper body 100 is configured to be able to accommodate the wearer's foot together with the sole 5.

[0022] The upper body 100 is composed of an outer foot portion 100L and an inner foot portion 100M. The outer foot portion 100L is located mainly on the outer foot side. The inner foot portion 100M is located mainly on the inner foot side. The inner foot portion 100M is connected to the outer foot portion 100L. More specifically, the inner foot portion 100M is connected to the outer foot portion 100L in front of the lacing region 10L. Furthermore, the inner foot portion 100M is connected to the outer foot portion 100L behind the opening 10A.

[0023] The upper body 100 has a slit 101. The slit 101 extends forward from the opening 10A and is located in the lacing region 10L so as to separate the outer foot portion 100L and the inner foot portion 100M from each other (see mainly FIG. 5).

[0024] As shown in FIG. 5, the outer foot portion 100L has a first extension portion 110. The first extension portion 110 is a portion of the upper body 100 located on one side as viewed from the slit 101. In other words, the first extension portion 110 is located in the lace-up area 10L. The first extension portion 110 extends toward the inner foot side. The first extension portion 110 is configured to be able to overlap with the inner foot portion 100M when viewed from above.

[0025] The inner foot portion 100M has a second extension portion 120. The second extension portion 120 is a portion of the upper body 100 located on the other side as viewed from the slit 101. In other words, the second extension portion 120 is located in the lace-up region 10L. The second extension portion 120 extends toward the outer foot portion 100L. The second extension portion 120 is configured to be able to overlap with the outer foot portion 100L when viewed from above.

[0026] The upper body 100 is made of knit fabric. As a result, the shoe according to this embodiment provides an improved fit to the wearer's foot. Furthermore, the upper body 100 made of knit fabric can eliminate the need for molding processes such as die-cutting to create the outer shape during the manufacturing process. This improves the production efficiency of the shoe 1. Furthermore, from the viewpoint of recyclability, the knit fabric is preferably made of fibers containing polyester resin as a main component.

[0027] Next, the tape member 200 will be described. The width of the tape member 200 is approximately constant in the direction of extension, and the tape member 200 has a tape-like outer shape. The width of the tape member 200 is, for example, 3 mm to 50 mm. The tape member 200 is sewn to the outer surface SA of the upper main body 100. The tape member 200 is flexible but has higher rigidity than the upper main body 100. From the viewpoint of recyclability, the tape member 200 is preferably made of a resin composition containing a polyester-based resin as a main component. From the viewpoint of reducing the environmental load, the polyester-based resin is more preferably made of recycled materials, and even more preferably made of only recycled materials.

[0028] The upper 10 may have at least one tape member 200, but in this embodiment, the upper 10 has a plurality of tape members 200. Specifically, the tape members 200 include an outer foot side tape member 200L attached to the outer surface SA of the upper main body 100 on the outer foot side, and an inner foot side tape member 200M attached to the outer surface SA of the upper main body 100 on the inner foot side. Therefore, the shoe 1 according to this embodiment has the tape members 200 provided on both the outer foot side and the inner foot side of the upper main body 100, which further improves the fit of the shoe 1.

[0029] In this embodiment, the lateral tape member 200L and the medial tape member 200M are separate tape members, but they may also be formed from a single continuous tape member (this variation will be described later). Furthermore, the lateral tape member 200L and the medial tape member 200M may have different structures. However, in this embodiment, the lateral tape member 200L and the medial tape member 200M may have the same structure. Therefore, in the following description of this embodiment, when the term "tape member 200" is used, the tape member 200 may be understood to refer to either the lateral tape member 200L or the medial tape member 200M.

[0030] The tape member 200 has a first band-shaped portion 210 , at least one folded portion 220 , and at least one second band-shaped portion 230 .

[0031] The first band portion 210 is located in the lace-up region 10L and extends along the front-to-rear direction of the upper 10. More specifically, the first band portion 210 extends along the front-to-rear direction and is positioned so as to slope downward as it extends forward (see FIGS. 3 and 4). Additionally, the first band portion 210 may extend along the front-to-rear direction and slope in either direction in the foot width direction as it extends forward (see FIG. 5).

[0032] The first band-like portion 210 is sewn to the upper body 100 so as to form a plurality of gaps G between the first band-like portion 210 and the upper body 100, through which the shoelaces L are passed. Specifically, the first band-like portion 210 is sewn to the upper body 100 by a plurality of stitched portions 300 (the stitched portions 300 will be described in detail later).

[0033] The outer foot portion 100L and the inner foot portion 100M are configured so that, by tying up the shoelaces L threaded through the multiple gaps G between the first band-shaped portion 210 and the upper body 100, the outer foot portion 100L and the inner foot portion 100M located on both sides of the slit 101 in the foot width direction overlap each other. This allows the upper 10 to wrap around the wearer's foot in the lacing region 10L even if the upper 10 does not further include a tongue. This configuration simplifies the configuration of the components associated with the lacing region 10L. Furthermore, because the outer foot portion 100L and the inner foot portion 100M of the upper body 100 are configured to overlap each other, the occurrence of wrinkles in the upper body 100 due to lacing up is suppressed. This ultimately improves the feel and fit of the shoe on the wearer's foot. At this time, more specifically, the first extending portion 110 overlaps with the inner leg portion 100M, and the second extending portion 120 overlaps with the outer leg portion 100L.

[0034] The folded portion 220 is continuous with at least one of the front end portion 211 and the rear end portion 212 of the first band-shaped portion 210. In this embodiment, the tape member 200 has two folded portions 220. More specifically, the folded portion 220 includes a front folded portion 221 and a rear folded portion 222. The front folded portion 221 is continuous with the front end portion 211 of the first band-shaped portion 210. The rear folded portion 222 is continuous with the rear end portion 212 of the first band-shaped portion 210. Hereinafter, in the description of this embodiment, when the term "folded portion 220" is simply used, the folded portion 220 may be understood as either the front folded portion 221 or the rear folded portion 222.

[0035] The folded portion 220 is formed by folding the tape member 200 downward when viewed from the first band-shaped portion 210 (see FIGS. 3 and 4). More specifically, the folded portion 220 is formed by folding the tape member 200 in a direction away from the lace fastening region 10L. The folded portion 220 is a portion where the tape member 200 overlaps as a result of being folded.

[0036] The second band portion 230 extends downward from the bent portion 220. In this embodiment, the tape member 200 has two second band portions 230. More specifically, the second band portion 230 includes a front second band portion 231 and a rear second band portion 232. The front second band portion 231 extends downward from the front bent portion 221. The rear second band portion 232 extends downward from the rear bent portion 222. Therefore, both the front second band portion 231 and the rear second band portion 232 for reinforcing the upper body 100 are provided by folding the tape member 200. This further simplifies the processing of the reinforcing member and the configuration of the member itself. When the length of the shoe 1 in the front-to-rear direction is Lx, the front second band-shaped portion 231 is provided, for example, at a distance in the range of 0.6Lx to 0.8Lx from the rear end of the shoe 1. The rear second band-shaped portion 232 is provided, for example, at a distance in the range of 0.2Lx to 0.5Lx from the rear end of the shoe 1.

[0037] Hereinafter, in the description of this embodiment, when the term "second band portion 230" is simply used, the second band portion 230 may be understood as either the front second band portion 231 or the rear second band portion 232.

[0038] More specifically, the second band portion 230 extends downward from the bent portion 220 while slanting backward. When viewed in the foot width direction, the rear second band portion 232 has a larger rearward slanting angle than the front second band portion 231. Note that the slanting angle here is the angle between the extension direction of the second band portion 230 and the up-down direction when viewed in the foot width direction. The second band portion 230 extends until it reaches the circumferential side surface 5S of the sole 5.

[0039] The second band portion 230 is fixed to the upper body 100. There are no particular limitations on the method for fixing the second band portion 230, but in this embodiment, it is fixed by being sewn to the upper body 100. This improves production efficiency by sewing the second band portion 230 together with the first band portion 210. Note that the second band portion 230 may also be fixed to the upper body 100 by a method other than sewing, for example, by adhesive.

[0040] The tape member 200 is not limited to the above-described configuration. FIG. 6 is a side view schematically showing a shoe according to a first modified example of the first embodiment of the present disclosure. As shown in FIG. 6, in the shoe 1a according to the first modified example of the first embodiment of the present disclosure, the bent portion 220a may be continuous only with the front end portion 211 of the first band-shaped portion 210. That is, the bent portion 220a may be only the front bent portion 221. The rear end portion 212a of the first band-shaped portion 210 may be the end of the entire tape member 200a. The second band-shaped portion 230a may be only the front second band-shaped portion 231.

[0041] Fig. 7 is a side view schematically showing a shoe according to a second modified example of the first embodiment of the present disclosure. As shown in Fig. 7, in a shoe 1b according to the second modified example of the first embodiment of the present disclosure, the bent portion 220b may be continuous only with the rear end portion 212 of the first band portion 210. That is, the bent portion 220b may be only the rear bent portion 222. The front end portion 211b of the first band portion 210 may be the end of the entire tape member 200b. The second band portion 230b may be only the rear second band portion 232.

[0042] Fig. 8 is a side view schematically illustrating a shoe according to a third modified example of the first embodiment of the present disclosure. Fig. 9 is a plan view schematically illustrating a shoe according to the third modified example of the first embodiment of the present disclosure. As shown in Figs. 8 and 9, in a shoe 1c according to the third modified example of the first embodiment of the present disclosure, the tape member 200c may further include a reverse bent portion 240c and a connecting strip portion 250c. In this modified example, the two reverse bent portions 240c may be positioned to correspond to the outer foot side tape member 200L and the inner foot side tape member 200M, respectively.

[0043] The reverse bent portion 240c may be continuous with the front end portion 211c of the first band-shaped portion 210. The reverse bent portion 240c may be formed by bending the tape member 200 upward when viewed from the first band-shaped portion 210 (see FIG. 8). More specifically, the reverse bent portion 240c may be formed by bending the tape member 200c in a direction toward the center of the upper 10 in the foot width direction (see FIG. 9).

[0044] The connecting strips 250c may extend in the foot width direction from the reverse bent portion 240c. The connecting strips 250c may be connected to both the reverse bent portion 240c of the lateral tape member 200L and the reverse bent portion 240c of the medial tape member 200M. Therefore, in this modification, the lateral tape member 200L and the medial tape member 200M may be formed from a single continuous tape member.

[0045] 1 to 5, in this embodiment, the upper 10 further includes a secondary tape member 290. The secondary tape member 290 extends from the end of the lateral tape member 200L opposite the rear bent portion 222 of the rear second band-shaped portion 232 to the end of the medial tape member 200M opposite the rear bent portion 222 of the rear second band-shaped portion 232. This makes the lateral tape member 200L and the medial tape member 200M appear to be made of a single tape member, improving the design of the shoe 1.

[0046] Additionally, the secondary tape member 290 is positioned so as to wrap around the rear of the upper body 100. The secondary tape member 290 is positioned so that a portion of it is separated from the upper body 100. This allows the wearer of the shoe 1 to put on the shoe 1 more easily by hooking their toes into the secondary tape member 290 when putting on the shoe 1.

[0047] The tape member 200 and the sub-tape member 290 may be formed from separate tape members. This eliminates the need to bend the tape member near the sole 5, and prevents the tape member from interfering with the joining of the sole 5 and the upper 10. The tape member 200 may also be formed from a single continuous tape member. This reduces the number of parts that make up the shoe 1.

[0048] Next, the multiple stitched portions 300 will be described. As shown in Figures 1 to 5, the multiple stitched portions 300 are provided by sewing the first band portion 210 to the upper main body 100 to form multiple gaps G. The multiple stitched portions 300 are arranged at intervals from one another in the extension direction D1 of the first band portion 210 (see Figures 1 and 2), so that the shoelace L passed through the gap G between the upper main body 100 and the first band portion 210 can be folded back around the stitched portion 300 on the outer surface SA of the upper main body 100 and locked with the stitched portion 300.

[0049] With the above configuration, when the wearer tightens the shoelace L, force is unlikely to be applied in a direction that would cause the first band-like portion 210 to peel away from the upper body 100. Furthermore, the stitch portion 300 that is engaged with the shoelace L pulls the upper body 100 and the first band-like portion 210 along the in-plane direction of the outer surface SA of the upper body 100. This allows the shoelace L to tighten along the outer surface SA of the foot of the wearer of the shoe, thereby providing more secure support for the foot of the wearer wearing the shoe.

[0050] Each of the plurality of stitched portions 300 is formed by sewing the thread-like members that make up the stitched portion 300 in a zigzag pattern to the upper body 100 and the tape member 200 (first band-like portion 210). The stitched portion 300 is a so-called zigzag stitch. Furthermore, each of the plurality of stitched portions 300 is firmly provided so that it can be locked with the shoelace L by being sewn in a zigzag pattern and with the thread-like members overlapping each other.

[0051] Each of the plurality of stitch portions 300 extends in a direction substantially perpendicular to the extension direction D1 (see FIGS. 1 and 2). However, the extension direction of each of the plurality of stitch portions 300 and the extension direction D1 of the first band portion 210 do not have to be perpendicular to each other. The number of the plurality of stitch portions 300 provided on one first band portion 210 is adjusted as appropriate.

[0052] The size of each of the multiple stitch portions 300 in the extension direction D1 is smaller than the distance between the multiple stitch portions 300. In other words, in this embodiment, the stitch width of the multiple stitch portions 300 (the length in the short side direction of the entire stitch portion 300) is smaller than the distance between the multiple stitch portions 300.

[0053] According to the above configuration, after the user passes the shoelace L through the gap G, the shoelace L can be folded back at the stitched portion 300 and passed between the stitched portions 300 that are spaced apart from each other by a relatively large distance. This makes it easier for the shoelace L to tighten in a direction along the outer surface SA of the foot of the wearer of the shoe.

[0054] In the width direction of the first band portion 210, each of the multiple stitch portions 300 is positioned so that its entirety overlaps the first band portion 210. The width direction of the first band portion 210 is a direction that is perpendicular to the extending direction D1 and that runs along the outer surface SA of the upper body 100.

[0055] In this embodiment, the multiple stitched portions 300 are configured so that when the shoelace L is engaged with the stitched portions 300, at least a portion of the folded portion L1 of the shoelace L is not positioned between the upper body 100 and the first band portion 210. In other words, as shown in FIG. 5 , at least a portion of the folded portion L1 of the shoelace L is configured to protrude from the first band portion 210 when the shoe 1 is viewed in plan. This configuration makes it easier for the user to pinch up the folded portion L1 of the shoelace L at the stitched portion 300, facilitating the user's adjustment of the tightness of the shoelace L. Specifically, the stitch length of each of the multiple stitched portions 300 (the longitudinal length of the entire stitched portion 300) is, for example, approximately 80% or more and less than 100% of the width dimension of the first band portion 210.

[0056] Next, in this embodiment, the configuration disposed on the inner surface SB of the upper body 100 will be described. Fig. 10 is a perspective view of a shoe according to embodiment 1 of the present disclosure, shown from the outer foot side, illustrating the configuration on the inner surface of the upper body. Fig. 11 is a perspective view of a shoe according to embodiment 1 of the present disclosure, shown from the inner foot side, illustrating the configuration on the inner surface of the upper body. Fig. 12 is a plan view of a shoe according to embodiment 1 of the present disclosure, showing the configuration on the inner surface of the upper body.

[0057] 10 to 12, the upper 10 further includes a first reinforcing portion 400, a second reinforcing portion 500, and a third reinforcing portion 600. In Figures 10 to 12, the first reinforcing portion 400 and the second reinforcing portion 500 located on the inner surface SB of the upper body 100 are schematically shown by relatively dense dots. In addition, the third reinforcing portion 600 located on the inner surface SB of the upper body 100 is shown by relatively sparse dots.

[0058] In this embodiment, the upper 10 has two first reinforcing portions 400 and two second reinforcing portions 500.

[0059] The two first reinforcing portions 400 include an outer foot-side first reinforcing portion 400L located on the outer foot side and an inner foot-side first reinforcing portion 400M located on the inner foot side. Hereinafter, when simply referring to a "first reinforcing portion 400," the first reinforcing portion 400 may be understood to mean either the outer foot-side first reinforcing portion 400L or the inner foot-side first reinforcing portion 400M.

[0060] The two second reinforcing portions 500 include an outer foot side second reinforcing portion 500L located on the outer foot side and an inner foot side second reinforcing portion 500M located on the inner foot side. Hereinafter, when simply referring to a "second reinforcing portion 500," the second reinforcing portion 500 may be understood to mean either the outer foot side second reinforcing portion 500L or the inner foot side second reinforcing portion 500M.

[0061] The first reinforcing portion 400 has higher rigidity than the upper body 100. The first reinforcing portion 400 is located on the inner surface SB of the upper body 100 so as to sandwich the upper body 100 together with the first band-shaped portion 210. More specifically, the first reinforcing portion 400 is sewn to the upper body 100 together with the first band-shaped portion 210. This makes it possible to suppress excessive stretching of the upper body 100 and firmly attach the first band-shaped portion 210 to the upper body 100, even if the rigidity of the upper body 100 is relatively low.

[0062] From the viewpoint of recyclability, the first reinforcing portion 400 is preferably made of a resin composition containing a polyester resin as a main component. The first reinforcing portion 400 is made of a sheet-like member. The thickness of the first reinforcing portion 400 is thinner than the thickness of the tape member 200. This allows the first reinforcing portion 400 to reinforce the upper 10 while preventing the fit of the upper 10 to the wearer from being impaired.

[0063] The first reinforcing portion 400 is entirely bonded to the inner surface SB of the upper body 100 with an adhesive. The first reinforcing portion 400 extends in the extension direction of the first band-shaped portion 210. When viewed in the thickness direction of the upper body 100, the first reinforcing portion 400 is positioned so as to substantially overlap the first band-shaped portion 210. The first reinforcing portion 400 is configured so that its width increases toward the rear.

[0064] The second reinforcement portion 500 has higher rigidity than the upper body 100. The second reinforcement portion 500 is fixed to a region of the upper body 100 between a portion where the front second band portion 231 is fixed and a portion where the rear second band portion 232 is fixed. The second reinforcement portion 500 extends in the up-and-down direction along the upper body 100. This prevents the region of the upper body 100 surrounded by the front first band portion 210, the front second band portion 231, and the rear second band portion 232 from stretching too much in the direction along the outer surface SA of the upper body 100 when the shoelace L is tightened. The second reinforcement portion 500 extends all the way to the circumferential side surface 5S of the sole 5.

[0065] The second reinforcing part 500 has a front second reinforcing part 510, a rear second reinforcing part 520, and at least one central second reinforcing part 530. The front second reinforcing part 510 is the part of the second reinforcing part 500 that is located most forward.

[0066] The rear second reinforcement portion 520 is the rearmost portion of the second reinforcement portion 500. The rear second reinforcement portion 520 is positioned away from the front second reinforcement portion 510. This prevents excessive restriction of stretch of the upper body 100 in the region surrounded by the front first band portion 210, the front second band portion 231, and the rear second band portion 232, thereby preventing a decrease in fit in that region.

[0067] The central second reinforcement portion 530 is located between the front second reinforcement portion 510 and the rear second reinforcement portion 520. The central second reinforcement portion 530 is located apart from both the front second reinforcement portion 510 and the rear second reinforcement portion 520. This makes it possible to more appropriately suppress stretching of the upper body 100 and suppress deterioration of the fit in the region surrounded by the front first band portion 210, the front second band portion 231, and the rear second band portion 232.

[0068] From the viewpoint of recyclability, the second reinforcing part 500 is preferably made of a resin composition containing a polyester resin as a main component. The second reinforcing part 500 is made of a sheet-like member. The thickness of the second reinforcing part 500 is thinner than the thickness of the tape member 200. This allows the second reinforcing part 500 to reinforce the upper 10 while preventing the fit of the upper 10 to the wearer from being impaired.

[0069] In this embodiment, the second reinforcing portion 500 is located on the inner surface SB of the upper body 100. The second reinforcing portion 500 is connected to the first reinforcing portion 400. The second reinforcing portion 500 and the first reinforcing portion 400 are made of a single member. Because the first reinforcing portion 400 and the second reinforcing portion 500 are made of a single member, the processing of the reinforcing portion members and the configuration of the members themselves are simplified. This in turn allows for improved production efficiency of the shoe 1.

[0070] More specifically, the front second reinforcing portion 510 extends downward from the front end of the first reinforcing portion 400 while following the front second band-shaped portion 231. The rear second reinforcing portion 520 extends downward from the rear end of the first reinforcing portion 400 so as to be approximately parallel to the first reinforcing portion 400. The central second reinforcing portion 530 extends downward from approximately the center of the first reinforcing portion 400 so as to be parallel to both the front second reinforcing portion 510 and the rear second reinforcing portion 520.

[0071] The second reinforcing portion 500 is not limited to the above configuration. The front second reinforcing portion 510, the rear second reinforcing portion 520, and the central second reinforcing portion 530 may be continuous and not spaced apart from one another. The second reinforcing portion 500 may have a plurality of central second reinforcing portions 530 that are spaced apart from one another.

[0072] The third reinforcing part 600 is located on the inner surface SB of the upper body 100. The third reinforcing part 600 is more rigid than the upper body 100, and is located at least forward of the tape member 200 (specifically, the front second band-shaped part 231). This makes it possible to prevent the upper body 100, which has a relatively low rigidity, from stretching too much even in front of the tape member 200 when the wearer puts on the shoe 1.

[0073] More specifically, the third reinforcing portion 600 is disposed in a portion of the upper body 100 that comes into contact with the sole 5. The third reinforcing portion 600 extends along the circumferential surface 5S of the sole 5. The third reinforcing portion 600 extends from the lateral foot side second reinforcing portion 500L to the medial foot side second reinforcing portion 500M.

[0074] As described above, the shoe 1 according to the first embodiment of the present disclosure includes a sole 5 and an upper 10. The upper 10 is located above the sole 5 and has an opening 10A through which the wearer's foot is inserted when the shoe is worn, and a lacing region 10L located in front of the opening 10A. The upper 10 includes an upper main body 100 and a tape-like tape member 200. The upper main body 100, together with the sole 5, can accommodate the wearer's foot. The tape member 200 is sewn to the outer surface SA of the upper main body 100. The tape member 200 is more rigid than the upper main body 100. The tape member 200 includes a first band-shaped portion 210, a folded portion 220, and a second band-shaped portion 230. The first band-shaped portion 210 is located in the lacing region 10L and extends along the front-to-rear direction of the upper 10. The folded portion 220 is continuous with at least one of the front end portion 211 and the rear end portion 212 of the first band-shaped portion 210. The folded portion 220 is formed by folding the tape member 200 downward when viewed from the first band-shaped portion 210. The second band-shaped portion 230 extends downward from the folded portion 220. The first band-shaped portion 210 is sewn to the upper main body 100 so that a plurality of gaps G for passing the shoelaces L through are formed between the first band-shaped portion 210 and the upper main body 100.

[0075] According to the above configuration, the first band-shaped portion 210 and the second band-shaped portion 230 for reinforcing the upper body 100 are provided by folding the tape member 200. This simplifies the processing of the reinforcing members and the configuration of the members themselves. Furthermore, the multiple gaps G for threading the shoelaces L are formed by sewing the first band-shaped portion 210 to the upper body 100. This simplifies the processing of the first band-shaped portion 210 and the configuration for threading the shoelaces L. Therefore, the above configuration can improve the production efficiency of shoes in which reinforcing members are arranged on the surface of the upper body 100.

[0076] [Shoe manufacturing method] Next, a method for manufacturing shoe 1 according to embodiment 1 of the present disclosure will be described. Fig. 13 is a flow diagram showing a method for manufacturing shoe according to embodiment 1 of the present disclosure. As shown in Fig. 13, the method for manufacturing shoe according to embodiment 1 of the present disclosure includes step S1 of preparing a sole, step S2 of manufacturing an upper, and step S3 of joining the upper to the top of the sole.

[0077] Process S2 of manufacturing the upper includes process S21 of preparing the upper body, process S22 of forming the folded portion, process S23 of sewing the first band portion, process S24 of attaching the second band portion, and process S25 of forming the upper.

[0078] Specifically, in step S21 of preparing the upper body, a plurality of flat knitted members that constitute the upper body 100 are prepared. Therefore, in the process of preparing the upper body 100, it is possible to omit the process of forming the outer shape, such as die cutting. This in turn improves the production efficiency of the shoe 1. Furthermore, when predetermined reinforcing members (for example, the first reinforcing member 400, the second reinforcing member 500, and the third reinforcing member 600) are provided on the inner surface SB of the upper body 100, these reinforcing members are bonded to the above-mentioned members with an adhesive or the like.

[0079] FIG. 14 is a plan view showing the tape member before being folded in the shoe manufacturing method according to the first embodiment of the present disclosure. FIG. 15 is a plan view showing the tape member immediately after being folded in the shoe manufacturing method according to the first embodiment of the present disclosure. As shown in FIGS. 14 and 15 , in step S22 of forming the folded portion, a tape member 200 in the form of a tape having higher rigidity than the upper body 100 is folded at a folding position P to form a folded portion 220. In this embodiment, the tape member is folded at a first folding position P1 and a second folding position P2 as the multiple folding positions P. As a result, a front folding portion 221 and a rear folding portion 222 are formed, respectively.

[0080] In step S22 of forming the folded portion, the tape member 200 folded at the folding position P as described above may be further heated and compressed using a heat press device. This stably maintains the outer shape of the folded portion 220. This in turn makes it possible to easily sew the first band-like portion 210 and the second band-like portion 230 to the upper body 100 in a later step. The above compression may be performed multiple times.

[0081] Furthermore, in the step S22 of forming the folded portion, the overlapping tape members 200 at the folded portion 220 may be sewn together as a temporary stitch. This stably maintains the outer shape of the folded portion 220. This in turn makes it possible to easily sew the first band-like portion 210 and the second band-like portion 230 to the upper main body 100 in a later step.

[0082] In step S23 of sewing the first band-like portion, the first band-like portion 210, which is a portion of the tape member 200 on one side as seen from the folded portion 220, is sewn to the outer surface SA of the upper main body 100 (specifically, a plurality of flat members made of knitted fabric) so as to be located in the lace-fastening region 10L and extend along the front-to-rear direction of the upper 10. The first band-like portion 210 is sewn to the upper main body 100 so as to form a plurality of gaps G between the first band-like portion 210 and the upper main body 100, through which the shoelaces L are passed. A plurality of stitched portions 300 are formed by step S23 of sewing the first band-like portion.

[0083] In step S24 of attaching the second band-like portion, the second band-like portion 230, which is the portion of the tape member 200 on the other side as seen from the folded portion 220, is attached to the outer surface SA of the upper main body 100 (specifically, a plurality of flat members made of knitted fabric) so as to extend downward from the folded portion 220. In this embodiment, the second band-like portion 230 is attached to the upper main body 100 by being sewn to the upper main body 100.

[0084] The order of step S23 of sewing the first band-shaped portion and step S24 of attaching the second band-shaped portion is not particularly limited. That is, step S23 of sewing the first band-shaped portion may be performed after step S24 of attaching the second band-shaped portion, or step S23 of sewing the first band-shaped portion and step S24 of attaching the second band-shaped portion may be performed simultaneously in parallel.

[0085] In step S25 of forming the upper, a plurality of flat knitted members prepared as members for constituting the upper body are placed over the last with the tape member 200 sewn and attached, and the edges of the members are sewn together at predetermined locations to produce the upper 10 of this embodiment.

[0086] Finally, in step S3, the upper 10 is joined to the upper side of the sole 5. The joining method is not particularly limited. Any conventionally known method can be used to join the upper 10 to the upper side of the sole 5. In this manner, the shoe according to the first embodiment of the present disclosure is manufactured.

[0087] As described above, the method for manufacturing a shoe according to embodiment 1 of the present disclosure includes a step S1 of preparing a sole 5, a step S2 of manufacturing an upper 10 having an opening 10A for inserting the wearer's foot when worn and a lacing area 10L located in front of the opening 10A, and a step S3 of joining the upper 10 to the upper side of the sole 5. The process S2 for manufacturing the upper 10 includes a process S21 for preparing the upper main body 100 capable of accommodating the wearer's foot together with the sole 5, a process S22 for forming a folded portion 220 by folding a tape member 200, which is a tape-like member having higher rigidity than the upper main body 100, at a folding portion P, a process S23 for sewing a first band-like portion 210, which is a portion of the tape member 200 on one side as viewed from the folding portion 220, to the outer surface SA of the upper main body 100 so as to be located in the lacing region 10L and extend along the front-to-rear direction of the upper 10, and a process S24 for attaching a second band-like portion 230, which is a portion of the tape member 200 on the other side as viewed from the folding portion 220, to the outer surface SA of the upper main body 100 so as to extend downward from the folding portion 220. The first band-like portion 210 is sewn to the upper main body 100 so as to form a plurality of gaps G between the first band-like portion 210 and the upper main body 100, through which shoelaces L can be passed.

[0088] According to the above configuration, the first band-shaped portion 210 and the second band-shaped portion 230 for reinforcing the upper body 100 are provided by folding the tape member 200. This simplifies the processing of the reinforcing members and the configuration of the members themselves. Furthermore, the multiple gaps G for threading the shoelaces L are formed by sewing the first band-shaped portion 210 to the upper body 100. This simplifies the processing of the first band-shaped portion 210 and the configuration for threading the shoelaces L. Therefore, according to the above configuration, a reinforcing member is disposed on the surface of the upper body 100, and a shoe manufacturing method with improved production efficiency can be provided.

[0089] (Embodiment 2) Hereinafter, a shoe according to a second embodiment of the present disclosure will be described. The shoe according to the second embodiment of the present disclosure differs from the shoe 1 according to the first embodiment of the present disclosure in the configuration of the stitching portion. Therefore, the description of the same configuration as the first embodiment of the present disclosure will not be repeated.

[0090] Fig. 16 is a plan view showing a shoe according to a second embodiment of the present disclosure. Note that in Fig. 16, the folded-back portion L1 of the shoelace L cannot be seen from above, but is indicated by a dashed line for convenience of explanation. As shown in Fig. 16, in the shoe 2 according to the second embodiment of the present disclosure, the multiple stitched portions 300x are configured so that when the shoelace L is engaged with the stitched portions 300x, the entire folded-back portion L1 of the shoelace L is positioned between the upper body 100 and the first band-like portion 210. Configuring the multiple stitched portions 300x in this manner reduces the chance of the folded-back portion L1 of the shoelace L at the stitched portions 300x being worn by other external objects.

[0091] Specifically, the stitch length of the plurality of stitch portions 300x is, for example, approximately 25% or more and less than 50% of the width dimension of the first band-shaped portion 210.
