[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-177736 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when multiple linear materials are bonded together across the entire upper, the bonding of the linear materials increases the rigidity of the entire upper, which can lead to problems such as a decrease in the upper's ability to follow the bending and twisting of the foot during movement, and fatigue failure of the material when the foot bends.

[0005] The present invention has been made in view of the above, and has an object to provide an upper that can reduce the rigidity of the upper. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the upper according to the present invention comprises an upper body having an upper forefoot portion covering the instep of the forefoot portion, an upper midfoot portion covering the instep of the midfoot portion, and an upper rearfoot portion covering the instep of the rearfoot portion, and at least a portion of the upper body includes an opening region in which an opening is formed and a joining region formed around the opening region, and a plurality of linear first members extending in one direction are arranged in the opening region in a non-joined state, and both ends of the first members are fixed ends fixed to the joining region of the upper body. The order in which the fixed ends on one end sides of the plurality of linear first members are arranged is equal to the order in which the fixed ends on the other end sides of the plurality of linear first members are arranged, the opening area in which the plurality of linear first members are arranged has lower rigidity than the joining area, and the joining area includes a first joining area arranged on the lower edges of the lateral side of the upper forefoot section, the upper midfoot section, and the upper rear foot section, a second joining area arranged on the lower edges of the medial side of the upper forefoot section, the upper midfoot section, and the upper rear foot section, and a third joining area arranged on the distal edge of the heel side of the upper rear foot section.

[0009] Hereinafter, embodiments of an upper and a shoe including the same according to the present invention will be described in detail with reference to the drawings, although the present invention is not limited to these embodiments.

[0010] In the embodiments described below, the direction in which the shoe center axis, which is a perpendicular line passing through the center of the shoe when viewed in a plan view, extends is referred to as the front-to-rear direction, and the direction perpendicular to the front-to-rear direction when viewed in a plan view is referred to as the left-to-right direction.

[0011] In addition, in the front-to-back direction, the direction from the end of the upper where the part covering the hind foot is located to the end of the upper where the part covering the forefoot is located is called the forward direction, and the direction from the end of the upper where the part covering the forefoot is located to the end of the upper where the part covering the hind foot is located is called the rear direction.

[0012] The side of the foot that is closest to the midline in the anatomical orthogonal position is called the medial side, and the side of the foot that is opposite the midline in the anatomical orthogonal position is called the lateral side. In other words, the side closest to the midline in the anatomical orthogonal position is called the medial side, and the side farthest from the midline in the anatomical orthogonal position is called the lateral side.

[0013] Furthermore, if the first boundary line is a line running left and right from the front end of the upper through a position equivalent to 25% to 50% of the front-to-back dimension of the upper, and the second boundary line is a line running left and right from the front end of the upper through a position equivalent to 55% to 80% of the front-to-back dimension of the upper, the part located in front of the first boundary line is called the upper forefoot part, the part sandwiched between the first and second boundary lines is called the upper midfoot part, and the part located behind the second boundary line is called the upper rearfoot part.

[0014] The upper forefoot portion corresponds to the portion covering the forefoot of a wearer with a standard body type, the upper midfoot portion corresponds to the portion covering the midfoot of a wearer with a standard body type, and the upper rearfoot portion corresponds to the portion covering the rearfoot of a wearer with a standard body type. That is, the first boundary line is a line that roughly follows the MP joint of a wearer with a standard body type, and the second boundary line is a line that roughly follows the Chopart joint of a wearer with a standard body type.

[0015] Furthermore, unless otherwise specified, the height direction means the direction perpendicular to both the front-to-back and left-to-right directions, and the thickness means the dimension in the height direction unless otherwise specified.

[0016] (Embodiment 1) FIG. 1 is a plan view of shoe 1 according to a first embodiment of the present invention. FIG. 2 is a side view of shoe 1 according to the first embodiment, showing the outer side of the foot. FIG. 1 shows only shoe 1 for the left foot. Since shoe 1 has a symmetrical structure for left and right feet, only shoe 1 for the left foot will be described in this embodiment, and description of shoe 1 for the right foot will be omitted. Shoe 1 may be, for example, a shoe for running or walking, a shoe for mountain climbing, or a shoe for sports such as tennis or basketball. As shown in FIG. 2, shoe 1 has an upper 2 and a sole 3 located below upper 2.

[0017] As shown in FIG. 1, the upper 2 includes an upper body 20, a shoe tongue 21, and shoelaces 22.

[0018] The upper body 20 mainly covers the instep side of the foot. An opening 20a for inserting the wearer's foot and a throat portion 20b communicating with the opening 20a and extending forward from the opening 20a are formed at the top of the upper body 20. At least a portion of the upper body 20 is an opening region 4 in which an opening is formed. In the opening region 4, a plurality of first members 5 extending in one direction are arranged in a non-bonded state. Details of the opening region 4 and the first members 5 will be described later. Note that although the first members 5 are actually linear, in Figures 1 and 2, the first members 5 are depicted as bands with diagonal hatching for ease of understanding.

[0019] The shoe tongue 21 is a component that protects the instep of the wearer. The shoe tongue 21 covers the throat portion 20b inside the upper body 20. The shoe tongue 21 is fixed to the upper body 20 by stitching, welding, bonding, or a combination of these. The upper body 20 and shoe tongue 21 are made of materials such as woven fabric, knitted fabric, synthetic leather, or resin. In shoes 1 that require particular breathability and lightness, the upper body 20 and shoe tongue 21 are preferably made of double raschel warp knitted fabric made from knitted polyester yarn. The materials for the upper body 20 and shoe tongue 21 are not limited to the materials exemplified above.

[0020] The shoelaces 22 are string-like members that are alternately hooked onto the first members 5 provided on both left and right edges of the throat portion 20b, and are detachably attached to the upper body 20.

[0021] As shown in FIG. 2, the sole 3 covers the sole of the foot. The sole 3 includes an outsole 30 and a midsole 31. The sole 3 is fixed to the upper body 20 by stitching, welding, adhesion, or a combination of these. The lower surface of the outsole 30 forms a contact surface 30a that is placed on the ground. The midsole 31 is located on the upper surface of the outsole 30 and has cushioning properties. The outsole 30 may be integrated with the midsole 31. The midsole 31 integrated with the outsole 30 is also called a "unisole."

[0022] Next, the configuration of the upper body 20 will be described in more detail with reference to Fig. 3. Fig. 3 is a development view of the upper 2 according to the first embodiment.

[0023] As shown in FIG. 3 , the upper body 20 includes an upper forefoot section 23 that covers the forefoot of a wearer with a standard build, an upper midfoot section 24 that covers the midfoot of a wearer with a standard build, an upper rearfoot section 25 that covers the rearfoot of a wearer with a standard build, and an upper sole section 26 that covers the sole of a wearer with a standard build. The upper forefoot section 23, upper midfoot section 24, and upper rearfoot section 25 are connected in this order in the front-to-rear direction from the front of the upper body 20. The upper forefoot section 23 is located forward of the first boundary line S1. The upper midfoot section 24 is located between the first boundary line S1 and the second boundary line S2. The upper rearfoot section 25 is located rearward of the second boundary line S2. The upper sole section 26 is connected to the lower edge of the upper midfoot section 24 on the lateral side of the foot. The upper sole portion 26 serves as a midsole that covers a lower opening formed by the lower edges of the upper forefoot portion 23, the upper midfoot portion 24, and the upper rearfoot portion 25. The upper sole portion 26 is fixed to the upper surface of the midsole 31 shown in FIG. 2 by adhesive or welding. The shoe 1 may also include an insole. If the shoe 1 includes an insole, the insole is placed on the upper sole portion 26 inside the upper 2.

[0024] The upper body 20 is formed with an opening region 4 in which the first member 5 is disposed, and a joining region 6 to which the first member 5 is fixed. The opening region 4 is an area that opens to the upper body 20 excluding the throat portion 20 b and the opening 20 a. The opening region 4 is formed across the upper forefoot portion 23, the upper midfoot portion 24, the upper rearfoot portion 25, and the upper sole portion 26. The opening region 4 is formed in a portion of the upper body 20 excluding the edge of the throat portion 20 b, the edge of the opening 20 a, the lower edge of the upper forefoot portion 23, the lower edge of the upper midfoot portion 24 excluding the boundary between the upper midfoot portion 24 and the upper sole portion 26, and the outer edge of the upper sole portion 26, and the lower edge and heel-side distal edge of the upper rearfoot portion 25.

[0025] The bonding region 6 is a planar region formed around the opening region 4. In other words, the opening region 4 is formed in the region surrounded by the bonding region 6. The configuration of the bonding region 6 is not particularly limited as long as it has a higher rigidity than the opening region 4 in which the first member 5 is arranged. Materials for the bonding region 6 include, for example, films, fibers, resins, and composites of fibers and resins. Fibers, resins, and composites of fibers and resins are bonded by knitting, weaving, braiding, welding, adhesives, and the like. The bonding region 6 is arranged along the outline of the upper body 20 in the unfolded state.

[0026] The joining region 6 includes a first joining region 61 arranged on the lateral lower edges of the upper forefoot section 23, the upper midfoot section 24, and the upper rearfoot section 25, a second joining region 62 arranged on the medial lower edges of the upper forefoot section 23, the upper midfoot section 24, and the upper rearfoot section 25, and a third joining region 63 arranged on the heel-side distal edge of the upper rearfoot section 25. The joining region 6 also includes a fourth joining region 64 arranged on the front edge of the throat section 20b, a fifth joining region 65 arranged on the lateral edge of the throat section 20b and the opening 20a, and a sixth joining region 66 arranged on the medial edge of the throat section 20b and the opening 20a. The bonding area 6 also includes a seventh bonding area 67 arranged on the outer edge of the upper sole 26, an eighth bonding area 68 arranged on the inner edge of the upper sole 26, and a ninth bonding area 69 arranged on the distal edge of the heel side of the upper sole 26.

[0027] The first bonding area 61 is not formed in a part of the boundary between the upper midfoot portion 24 and the upper sole portion 26. The first bonding area 61 and the second bonding area 62 extend from the rear to the front so as to approach the shoe center axis C. The front ends of the first bonding area 61 and the second bonding area 62 are connected to each other. The rear ends of the first bonding area 61 and the second bonding area 62 are connected to the lower end of the third bonding area 63. The fifth bonding area 65 and the sixth bonding area 66 extend forward from the upper end of the third bonding area 63 toward the fourth bonding area 64. The front ends of the seventh bonding area 67 and the eighth bonding area 68 are connected to each other. The rear end of the seventh bonding area 67 is connected to the first bonding area 61. The end of the ninth bonding area 69 on the outer side of the foot is connected to the first bonding area 61.

[0028] The multiple first members 5 are linear members extending across the opening region 4 in the left-right or height direction. The multiple first members 5 are arranged at intervals from one another in the front-to-rear direction. The first members 5 are formed of a single material. The first members 5 are, for example, fibers, threads formed by bundling multiple fibers, or linear resin, and are flexible. The first members 5 are stretchable in only one direction. The first members 5 are arranged in the upper forefoot portion 23, the upper midfoot portion 24, the upper rearfoot portion 25, and the upper sole portion 26. The first member 5 in the upper forefoot portion 23 extends in the left-right direction between the first bonding region 61 and the second bonding region 62. The first member 5 located on the lateral side of the upper midfoot portion 24 extends from the fifth bonding region 65 through the boundary between the upper midfoot portion 24 and the upper sole portion 26 to the eighth bonding region 68. The first member 5 located on the medial side of the upper midfoot portion 24 extends in the height direction between the sixth bonding region 66 and the second bonding region 62. The first member 5 located on the lateral side of the upper rearfoot portion 25 extends in the height direction between the fifth bonding region 65 and the first bonding region 61. The first member 5 located on the medial side of the upper rearfoot portion 25 extends in the height direction between the sixth bonding region 66 and the second bonding region 62. The first member 5 located on the upper sole portion 26 extends in the left-right direction between the seventh bonding region 67 and the eighth bonding region 68, or extends in the left-right direction between the boundary between the upper midfoot portion 24 and the upper sole portion 26 and the eighth bonding region 68.

[0029] Each of the multiple first members 5 has a fixed end 50 fixed to the joining region 6 of the upper body 20 adjacent to the opening region 4. Hereinafter, when distinguishing between the fixed ends 50 of the first members 5, the fixed end 50 on one end of the first member 5 will be referred to as the fixed end 51, and the fixed end 50 on the other end of the first member 5 will be referred to as the fixed end 52. The fixed ends 51 on one end of the multiple first members 5 are aligned in the front-to-rear direction. The fixed ends 52 on the other end of the multiple first members 5 are aligned in the front-to-rear direction. The order in which the fixed ends 51 on one end of the multiple first members 5 are aligned is the same as the order in which the fixed ends 52 on the other end of the multiple first members 5 are aligned. The spacing between adjacent fixed ends 50 in the front-to-rear direction may be different on one end and the other end, but in this embodiment, it is the same on one end and the other end. The multiple first members 5 are arranged parallel to each other. The shoelace 22 is passed through a gap formed between adjacent first members 5 and is hung on the first members 5.

[0030] Next, the effects of the upper 2 according to this embodiment will be described.

[0031] In this embodiment, as shown in FIG. 1 , the upper 2 includes an upper main body 20 that covers the instep, and as shown in FIG. 3 , at least a portion of the upper main body 20 is an opening region 4 in which an opening is formed. Furthermore, in the opening region 4, a plurality of first members 5 extending in one direction are arranged in a mutually unbonded state. Furthermore, both ends of the first members 5 are fixed ends 50 that are fixed to a joining region 6 of the upper main body 20 adjacent to the opening region 4, and the order in which the fixed ends 51 on one end of the plurality of first members 5 are arranged is the same as the order in which the fixed ends 52 on the other end of the plurality of first members 5 are arranged. With this configuration, the opening region 4 in which the first members 5 are arranged has lower rigidity than the joining region 6 adjacent to the opening region 4, and therefore the rigidity of the upper main body 20 can be locally reduced.

[0032] When the upper rear foot portion 25 is lifted off the ground while the upper forefoot portion 23 shown in FIG. 3 is in contact with the ground, the forefoot portion bends, creating a bent portion in the upper forefoot portion 23. In this embodiment, the first member 5 is disposed in the upper forefoot portion 23 where the bent portion is created, thereby reducing the bending rigidity of the portion of the upper forefoot portion 23 where the bent portion is created. This reduces the bending resistance of the upper main body 20 when the foot bends. Furthermore, because the first member 5 is more likely to deform in response to the bending of the foot, the feel of the upper main body 20 on the foot can be alleviated and fatigue failure of the material of the upper main body 20 can be suppressed. By suppressing fatigue failure of the material of the upper main body 20, the strength required for the material of the upper main body 20 can be reduced, leading to a lighter shoe 1.

[0033] In this embodiment, as shown in FIG. 3, the first member 5 is disposed in a part of the foot that has large curvature in multiple directions, so that the upper body 20 can fit well along the foot.

[0034] During movement, distortions such as shrinkage and twisting occur mainly in the skin of the midfoot region, causing shear deformation in the upper midfoot portion 24 shown in FIG. 3. In this embodiment, the first member 5 is disposed in the upper midfoot portion 24, thereby reducing the rigidity of the upper midfoot portion 24. This allows the first member 5 to more easily deform in response to distortions in the skin of the foot, thereby suppressing the occurrence of wrinkles in the upper main body 20 and also suppressing fatigue failure of the material of the upper main body 20. By suppressing fatigue failure of the material of the upper main body 20, the strength required for the material of the upper main body 20 can be reduced, leading to a lighter shoe 1.

[0035] 3, in this embodiment, the shoelace 22 is hooked onto the first member 5, and the first member 5 serves as a substitute for the eyelet, eliminating the need to form a separate eyelet. Also, by hooking the shoelace 22 onto some of the multiple first members 5, the tightening force generated by tensioning the shoelace is applied to some of the first members 5, allowing the upper body 20 to be tightened locally.

[0036] In this embodiment, as shown in Figure 3, multiple first members 5 extending in one direction are arranged in the opening region 4 in a non-bonded state, thereby improving the breathability between the inside and outside of the upper body 20 and reducing the weight of the shoe 1.

[0037] In this embodiment, the distance between adjacent fixed ends 50 is the same on both ends, which makes it difficult for the first members 5 to cross each other. This makes the first members 5 more susceptible to shear deformation, so that the first members 5 are more likely to deform in accordance with the distortion of the skin of the foot during movement.

[0038] In this embodiment, the first member 5 shown in FIG. 3 is formed from a single material, and therefore the upper body 20 including the first member 5 can be easily manufactured.

[0039] (Embodiment 2) Fig. 4 is a plan view of a shoe 1A according to a second embodiment of the present invention. Fig. 5 is a side view of the shoe 1A according to the second embodiment on the lateral side of the foot. Fig. 6 is a developed view of an upper 2A according to the second embodiment. The upper 2A according to the second embodiment differs from the upper 2 according to the first embodiment in that the upper 2A has a monosock structure and in the range of the opening region 4A and the first member 5A. In the second embodiment, parts that overlap with those in the first embodiment are designated by the same reference numerals and will not be described.

[0040] As shown in Figures 4 and 5, the upper 2A has a monosock structure in which a portion corresponding to the tongue 21 of the first embodiment is integrated with the ankle portion of the upper body 20A. As shown in Figure 6, a portion of the connection region 6A is formed in front of the opening 20a of the upper body 20A. Hereinafter, this portion of the connection region 6A will be referred to as the central connection region 6B. In this embodiment, the opening region 4A is formed across the upper forefoot portion 23, the upper midfoot portion 24, and the upper sole portion 26. The opening region 4A is formed from the front edge of the central connection region 6B to near the center of the upper forefoot portion 23 in the front-to-rear direction. The opening region 4A is also formed from the outer foot side edge of the central connection region 6B to near the lower edge of the outer foot side of the upper forefoot portion 23 and the midfoot portion of the upper sole portion 26. Furthermore, the opening region 4A is formed from the medial edge of the central joining region 6B to the vicinity of the medial lower edges of the upper forefoot portion 23 and the upper midfoot portion 24.

[0041] A plurality of first members 5A extending in one direction are arranged in the opening region 4A in a mutually unjoined state. The first members 5A are arranged in the upper forefoot portion 23, the upper midfoot portion 24, and the upper sole portion 26. The first members 5A bridge between the portions of the joining region 6A that are arranged on either side of the opening region 4A. This embodiment can also achieve the same effects as the first embodiment described above.

[0042] (Embodiment 3) Fig. 7 is a plan view of shoe 1B according to embodiment 3 of the present invention. Fig. 8 is a side view of shoe 1B according to embodiment 3 on the outer side of the foot. An upper 2B according to embodiment 3 differs from the upper 2 according to embodiment 1 in the range of an opening region 4B and a first member 5B. In embodiment 3, parts that overlap with embodiment 1 described above are denoted by the same reference numerals and description thereof will be omitted.

[0043] As shown in FIGS. 7 and 8, the opening region 4B is formed in the upper midfoot portion 24 in this embodiment. The opening region 4B is formed on each of the lateral and medial sides of the throat portion 20b. The opening region 4B is formed from near the edge of the lateral side of the throat portion 20b to near the lower edge of the lateral side of the upper midfoot portion 24. The opening region 4B is formed from near the edge of the medial side of the throat portion 20b to near the lower edge of the medial side of the upper midfoot portion 24. The first member 5B is disposed in the upper midfoot portion 24. As shown in FIG. 8, the first member 5B extends from the edge of the lateral side or the edge of the medial side of the throat portion 20b toward the sole 3. The lower end of the first member 5B reaches near the lower edge of the upper midfoot portion 24. The extension direction of the first member 5B is inclined so that it is positioned more rearward as it moves from the edge of the throat portion 20b toward the sole 3.

[0044] This embodiment can achieve substantially the same effects as the first embodiment. In other words, in this embodiment, the first member 5B is disposed in the upper midfoot portion 24, which allows the first member 5B to easily deform in response to strains in the skin of the foot. This prevents wrinkles from forming in the upper body 20B and also prevents fatigue failure of the material of the upper body 20B. By preventing fatigue failure of the material of the upper body 20B, the strength required for the material of the upper body 20B can be reduced, leading to a lighter shoe 1B. In this embodiment, the shoelace 22 is fastened to the first member 5B, which serves as a substitute for an eyelet, eliminating the need for a separate eyelet. Furthermore, by fastening the shoelace 22 to some of the first members 5B, the tightening force generated by tensioning the shoelace is applied to some of the first members 5B, thereby locally tightening the upper body 20B. In addition, in this embodiment, multiple first members 5B extending in one direction are arranged in the opening region 4B in a non-bonded state to each other, thereby improving the breathability between the inside and outside of the upper body 20B and reducing the weight of the shoe 1B.

[0045] (Fourth embodiment) Fig. 9 is a plan view of shoe 1C according to embodiment 4 of the present invention. Fig. 10 is a side view of shoe 1C according to embodiment 4 on the outer side of the foot. An upper 2C according to embodiment 4 differs from the upper 2 according to embodiment 1 in the range of an opening region 4C and a first member 5C, and in that a lace-insertion section 27 is provided in an upper body 20C. Note that in embodiment 4, parts that overlap with those in embodiment 1 described above are given the same reference numerals, and description thereof will be omitted.

[0046] As shown in FIGS. 9 and 10 , the opening region 4C is formed in the upper forefoot portion 23 in this embodiment. The opening region 4C is formed from the lower edge of the lateral side of the upper forefoot portion 23, passing in front of the throat portion 20b, to the lower edge of the medial side of the upper forefoot portion 23. The first member 5C is disposed in the upper forefoot portion 23 and extends in the left-right direction. The end of the first member 5C on the lateral side reaches the lower edge of the lateral side of the upper forefoot portion 23. The end of the first member 5C on the medial side reaches the lower edge of the medial side of the upper forefoot portion 23. As shown in FIG. 10 , the extension direction of the first member 5C is inclined so that it is positioned further rearward from the shoe center axis toward the lower edge of the upper forefoot portion 23. As shown in FIG. 9 , a plurality of lace insertion portions 27 spaced apart in the front-rear direction are provided on both lateral edges of the throat portion 20b. The lace passage 27 is not particularly limited in configuration as long as it can pass the shoelace 22 through it, but in this embodiment it is a through-hole that passes through the upper body 20C in the vertical direction.

[0047] This embodiment can achieve substantially the same effects as the first embodiment. In other words, in this embodiment, the first member 5C is disposed in the upper forefoot portion 23 where the bending portion occurs. This allows the first member 5C to easily deform in accordance with the bending of the foot, thereby mitigating the impact of the upper body 20C on the foot and suppressing fatigue failure of the material of the upper body 20C. Suppressing fatigue failure of the material of the upper body 20C reduces the strength required for the material of the upper body 20C, leading to a reduction in the weight of the shoe 1C. Furthermore, in this embodiment, multiple first members 5C extending in one direction are disposed in the opening region 4C in a non-bonded state, thereby improving breathability between the interior and exterior of the upper body 20C and reducing the weight of the shoe 1C.

[0048] (Embodiment 5) Fig. 11 is a plan view of a shoe 1D according to a fifth embodiment of the present invention. Fig. 12 is a side view of the outer side of the foot of the shoe 1D according to the fifth embodiment. An upper 2D according to the fifth embodiment differs from the upper 2 according to the first embodiment in the range of the opening region 4D and the first member 5D, and in that a lace-insertion section 27 is provided in the upper body 20D. In the fifth embodiment, parts that overlap with those in the first embodiment are designated by the same reference numerals, and description thereof will be omitted.

[0049] As shown in FIGS. 11 and 12, in this embodiment, the opening region 4D is formed from the upper midfoot portion 24 to the upper rearfoot portion 25. As shown in FIG. 11, the opening region 4D is formed from the lateral edge of the throat portion 20b, passing through the heel-side distal edge of the upper rearfoot portion 25, and extending to the medial edge of the throat portion 20b. The first member 5D is disposed from the upper midfoot portion 24 to the upper rearfoot portion 25. The first member 5D extends from the lateral edge of the throat portion 20b toward the upper rearfoot portion 25, passing through the heel-side distal edge of the upper rearfoot portion 25, and extending to the medial edge of the throat portion 20b. The first member 5D extends to surround the shoe opening 20a. As shown in FIG. 12, the extension direction of the first member 5D is inclined downward from the lateral and medial edges of the throat portion 20b toward the upper rearfoot portion 25. 11, multiple lace-insertion sections 27 spaced apart in the front-rear direction are provided on both left and right edges of the throat section 20b. The rear ends of the shoelaces 22 are hooked onto the first members 5 and exposed to the outside of the upper body 20D through the gaps between adjacent first members 5.

[0050] This embodiment can achieve substantially the same effects as the first embodiment. In other words, in this embodiment, the shoelace 22 is hooked onto the first member 5D, and the first member 5D serves as a substitute for an eyelet, eliminating the need for a separate eyelet. Furthermore, the shoelace 22 is hooked onto some of the first members 5D, and the tightening force generated by tensioning the shoelace 22 is applied to some of the first members 5D, thereby locally tightening the upper body 20D. In particular, in this embodiment, the first members 5D extend to surround the opening 20a, thereby locally tightening the portion of the upper body 20D around the opening 20a. Furthermore, in this embodiment, multiple first members 5D extending in one direction are arranged in the opening region 4D without being joined to each other, thereby improving breathability between the inside and outside of the upper body 20D and reducing the weight of the shoe 1D.

[0051] (Embodiment 6) FIG. 13 is a plan view of a shoe 1E according to a sixth embodiment of the present invention, showing the state before the shoelace 22 is pulled. FIG. 14 is a side view of the shoe 1E according to the sixth embodiment on the lateral side of the foot. FIG. 15 is a plan view of the shoe 1E according to the sixth embodiment, showing the state after the shoelace 22 has been pulled from the state shown in FIG. 13. An upper 2E according to the sixth embodiment differs from the upper 2 according to the first embodiment in the scope and configuration of an opening region 4E and a first member 5E. In the sixth embodiment, parts that overlap with those in the first embodiment are denoted by the same reference numerals and will not be described again. In FIGS. 13 to 15, for ease of understanding, the opening region 4E is illustrated with dot hatching, and the first member 5E is omitted in FIGS. 13 and 15.

[0052] As shown in FIGS. 13 and 14, the opening region 4E is formed in the upper midfoot portion 24 in this embodiment. The opening region 4E is adjacent to the lateral edge of the throat portion 20b, and is formed from the lateral edge of the throat portion 20b to near the lower edge of the lateral side of the upper midfoot portion 24. The opening region 4E is adjacent to the medial edge of the throat portion 20b, and is formed from the medial edge of the throat portion 20b to near the lower edge of the medial side of the upper midfoot portion 24. As shown in FIG. 14, the first member 5E is disposed in the upper midfoot portion 24. The first member 5E extends from the lateral edge of the throat portion 20b toward the sole 3 in the lateral opening region 4E. The lower end of the lateral side of the first member 5E reaches near the lower edge of the upper midfoot portion 24. Although not shown, in the medial opening region 4E, the first member 5E similarly extends from the medial edge of the throat portion 20b toward the sole 3. The medial lower end of the first member 5E reaches near the lower edge of the upper midfoot portion 24. The extension direction of the first member 5E is inclined so that it is positioned further rearward from the lateral and medial edges of the throat portion 20b toward the sole 3.

[0053] The first member 5E includes a first elongate member 53 and a second elongate member 54 having higher extensibility in one direction than the first elongate member 53. The opening region 4E includes a first region 41 in which a plurality of first elongate members 53 are arranged in the front-to-rear direction, and a second region 42 in which a plurality of second elongate members 54 are arranged in the front-to-rear direction. The first region 41 and the second region 42 are alternately arranged in the front-to-rear direction on the lateral foot side and medial foot side of the throat portion 20b. Note that in Figures 13 to 15, the first region 41 and the second region 42 are distinguished from each other by the shade of dot hatching.

[0054] As shown in Fig. 13, the upper 2E includes a front edge 20c, a first side edge 20d, a second side edge 20e, a plurality of first forming portions 20f, a plurality of second forming portions 20g, and a plurality of lace-through portions 27. Hereinafter, when distinguishing between the plurality of lace-through portions 27, they will be referred to as the lateral foot-side lace-through portion 27a, the medial foot-side lace-through portion 27b, the toe-side lace-through portion 27c, and the heel-side lace-through portion 27d. Although the lateral foot-side lace-through portion 27a, the medial foot-side lace-through portion 27b, the toe-side lace-through portion 27c, and the heel-side lace-through portion 27d are actually gaps formed between adjacent first members 5E, in Figs. 13 to 15, the lace-through portions 27 are illustrated as circular holes for ease of understanding.

[0055] The front edge 20c is the front edge of the throat 20b. The front edge 20c extends in the left-right direction. The first side edge 20d is the edge on the outer side of the throat 20b. The second side edge 20e is the edge on the inner side of the throat 20b. The first side edge 20d and the second side edge 20e extend in the front-to-back direction.

[0056] The first forming portion 20f is a part of the second region 42 and protrudes from the first side edge 20d toward the second side edge 20e. The shape of the first forming portion 20f in a plan view is not particularly limited, but in this embodiment it is a rectangle with rounded corners. The shape of the first forming portion 20f in a plan view may also be a polygon or semicircle. The number of first forming portions 20f is not particularly limited, but in this embodiment it is two. The two first forming portions 20f are spaced apart from each other in the front-to-rear direction. Note that the first forming portion 20f may be a part of either the first region 41 or the second region 42.

[0057] The second forming portion 20g is a part of the second region 42 and protrudes from the second side edge 20e toward the first side edge 20d. The shape of the second forming portion 20g in a plan view is not particularly limited, but in this embodiment, it is a rectangle with rounded corners. The shape of the second forming portion 20g in a plan view may also be a polygon or semicircle. The number of second forming portions 20g is not particularly limited, but in this embodiment, there are two. The two second forming portions 20g are spaced apart from each other in the front-to-rear direction. The first forming portion 20f and the second forming portion 20g are alternately arranged in the front-to-rear direction. In this embodiment, the second forming portion 20g and the first forming portion 20f are alternately arranged from front to rear in this order. Note that the second forming portion 20g may be a part of either the first region 41 or the second region 42.

[0058] One toe-side lace-threading portion 27c is provided on the outer side of the throat portion 20b. The toe-side lace-threading portion 27c is provided forward of the outer side lace-threading portion 27a. The toe-side lace-threading portion 27c is provided near the boundary between the first side edge portion 20d and the front edge portion 20c.

[0059] Each outer foot-side lace-through portion 27a is made up of a pair of a first lace-through portion 27e provided in the first formation portion 20f and a second lace-through portion 27f spaced apart from the first lace-through portion 27e toward the outer foot. The first lace-through portion 27e is located in the second region 42. The second lace-through portion 27f is located in the first region 41. The number of pairs of outer foot-side lace-through portions 27a is not particularly limited, but in this embodiment, there are two pairs. The two pairs of outer foot-side lace-through portions 27a are spaced apart from each other in the front-to-back direction. The first lace-through portion 27e and the second lace-through portion 27f are offset from each other in the front-to-back direction and the left-to-right direction. In each pair of outer foot-side lace-through portions 27a, the second lace-through portion 27f is spaced apart from the first lace-through portion 27e toward the outer foot and rearward. The second lace-through portion 27f is located on the outer side of the first side edge 20d. The outer side lace-through portion 27a may be located in at least one of the first region 41 and the second region .

[0060] Each medial side lace-through portion 27b is formed as a set including a third lace-through portion 27g provided in the second formation portion 20g and a fourth lace-through portion 27h spaced medially from the third lace-through portion 27g. The third lace-through portion 27g is located in the second region 42. The fourth lace-through portion 27h is located in the first region 41. The number of sets of medial side lace-through portions 27b is not particularly limited, but in this embodiment, there are two sets. The two sets of medial side lace-through portions 27b are spaced apart from each other in the front-to-back direction. The third lace-through portion 27g and the fourth lace-through portion 27h are offset from each other in the left-right direction and the front-to-back direction. In each set of medial side lace-through portions 27b, the fourth lace-through portion 27h is spaced medially and forward from the third lace-through portion 27g. The fourth lace-through portion 27h is located medially relative to the second side edge portion 20e. The fourth lace-through portion 27h, which is located most forward of the two pairs of medial lace-through portions 27b, is located symmetrically with the toe-side lace-through portion 27c across the throat portion 20b. In this embodiment, the first lace-through portion 27e is located on the lateral side of the foot and spaced rearward from the third lace-through portion 27g; however, the first lace-through portion 27e and the third lace-through portion 27g may be arranged side by side in the front-to-rear direction. The medial lace-through portion 27b may be located in at least one of the first region 41 and the second region 42.

[0061] The heel-side lace-through portion 27d is located further back than the lateral and medial lace-through portions 27a and 27b. In this embodiment, two heel-side lace-through portions 27d are provided, one on the lateral side and one on the medial side of the throat portion 20b. The two heel-side lace-through portions 27d are located symmetrically on either side of the throat portion 20b. The heel-side lace-through portion 27d is located near the boundary between the edge of the throat portion 20b and the edge of the opening 20a.

[0062] The shoelace 22 is threaded through the toe-side threading portion 27c, the outer foot-side threading portion 27a, the inner foot-side threading portion 27b, and the heel-side threading portion 27d. Although not shown, both longitudinal ends of the shoelace 22 are tied with a bow or similar. The shoelace 22 has a first portion 22a that is threaded alternately through the second threading portion 27f and the third threading portion 27g, a second portion 22b that is threaded alternately through the first threading portion 27e and the fourth threading portion 27h, and a third portion 22c that extends between the toe-side threading portion 27c and the forward-most fourth threading portion 27h to connect the first portion 22a and the second portion 22b. The third portion 22c extends laterally across the throat portion 20b.

[0063] The first portion 22a extends diagonally rearward from the toe-side lace-through portion 27c and is threaded alternately through the third lace-through portion 27g and the second lace-through portion 27f, and then threaded through the heel-side lace-through portion 27d on the outside of the foot. As shown in Figure 13, before the shoelace 22 is pulled, the second lace-through portion 27f and the third lace-through portion 27g are offset in the front-to-back and left-to-right directions. Therefore, the first portion 22a, which is threaded alternately through the second lace-through portion 27f and the third lace-through portion 27g, extends in a zigzag pattern left-to-right from the front to the rear.

[0064] The second portion 22b extends diagonally rearward from the fourth lace-through portion 27h, which is located at the forefront, and is threaded alternately through the first lace-through portion 27e and the fourth lace-through portion 27h before being threaded through the heel-side lace-through portion 27d on the medial side of the foot. Before the shoelace 22 is pulled, the first lace-through portion 27e and the fourth lace-through portion 27h are offset in the front-to-back and left-to-right directions. Therefore, the second portion 22b, which is threaded alternately through the first lace-through portion 27e and the fourth lace-through portion 27h, extends in a zigzag pattern left-to-right from the front to the rear. Before the shoelace 22 is pulled, the first portion 22a and the second portion 22b do not intersect with each other. Before the shoelace 22 is pulled, the portions of the first portion 22a that are alternately threaded through the second lace-passing portion 27f and the third lace-passing portion 27g and the portions of the second portion 22b that are alternately threaded through the first lace-passing portion 27e and the fourth lace-passing portion 27h are parallel to each other.

[0065] 15, by pulling the first portion 22a and the second portion 22b rearward from the state shown in Fig. 13, the first side edge 20d and the second side edge 20e of the upper body 20E are drawn toward each other. This reduces the left-right distance between the second lace-through portion 27f and the third lace-through portion 27g, and reduces the left-right distance between the first lace-through portion 27e and the fourth lace-through portion 27h. Therefore, the first portion 22a, which is alternately threaded through the second lace-through portion 27f and the third lace-through portion 27g, approaches a state in which it extends linearly in the front-to-rear direction, and the second portion 22b, which is alternately threaded through the first lace-through portion 27e and the fourth lace-through portion 27h, approaches a state in which it extends linearly in the front-to-rear direction. When the shoelace 22 threaded through the lateral and medial lace-threading portions 27a, 27b is pulled, the first and second portions 22a, 22b do not cross each other. When the shoelace 22 threaded through the lateral and medial lace-threading portions 27a, 27b is pulled, the portions of the first portion 22a that are alternately threaded through the second and third lace-threading portions 27f, 27g are parallel to the portions of the second portion 22b that are alternately threaded through the first and fourth lace-threading portions 27e, 27h.

[0066] This embodiment can achieve substantially the same effects as those of the above-described embodiment 1. That is, in this embodiment, a plurality of first members 5E extending in one direction are arranged in the opening region 4E in a mutually unjoined state, which improves the breathability between the inside and outside of the upper body 20E and also reduces the weight of the shoe 1E.

[0067] In this embodiment, when shoelace 22 is pulled, first portion 22a and second portion 22b do not cross each other on the instep as shown in Fig. 15. This reduces pressure on the instep compared to when shoelace 22 crosses over the instep, and can alleviate the feeling of tightness on the instep.

[0068] In this embodiment, as shown in Fig. 14, the first region 41 in which multiple first elongate members 53 are arranged and the second region 42 in which multiple second elongate members 54 are arranged are alternately arranged in the front-to-rear direction on the lateral and medial sides of the throat portion 20b, and as shown in Fig. 15, the lateral lace-through portion 27a and the medial lace-through portion 27b are arranged in the first region 41 and the second region 42, making it easier to draw the first side edge 20d and the second side edge 20e together when the shoelace 22 is pulled. This allows the upper 2E to fit snugly against the foot.

[0069] In this embodiment, as shown in Figure 15, the outer foot-side lace-through portions 27a, each consisting of a pair of one first lace-through portion 27e and one second lace-through portion 27f, and the inner foot-side lace-through portions 27b, each consisting of a pair of one third lace-through portion 27g and one fourth lace-through portion 27h, are arranged alternately in the front-to-rear direction. That is, because there are two lace-through portions 27 alternately on the outer foot side and the inner foot side of the throat portion 20b, the force that draws the first side edge 20d and the second side edge 20e together when the shoelace 22 is pulled is stronger than when there are only one lace-through portion 27 alternately on the outer foot side and the inner foot side of the throat portion 20b. This allows the upper 2E to fit snugly against the foot.

[0070] (Embodiment 7) 16 is a perspective view schematically showing a first member 5F of a shoe according to embodiment 7 of the present invention. An upper 2F according to embodiment 7 differs from the upper 2 according to embodiment 1 in the configuration of the first member 5F. In embodiment 7, parts that overlap with those in embodiment 1 described above are given the same reference numerals and descriptions thereof will be omitted.

[0071] The first member 5F is a flexible cylindrical tube. In the present embodiment, the shape of the first member 5F is cylindrical, but it may be a square cylindrical shape or the like. According to this embodiment, it is possible to achieve the same effects as those of the first embodiment.

[0072] (Embodiment 8) 17 is a development view of a shoe upper 2G according to an eighth embodiment of the present invention. The upper 2G according to the eighth embodiment differs from the upper 2 according to the first embodiment in that it includes a second member 7. In the eighth embodiment, parts that overlap with those in the first embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0073] In the opening region 4, a plurality of second members 7 extending in one direction are arranged in a non-bonded state. The plurality of second members 7 are linear members extending longitudinally across the opening region 4 in the front-to-rear direction. The plurality of second members 7 are arranged at intervals from each other in the left-to-right direction. The second members 7 are formed of a single material. The second members 7 are, for example, fibers, threads formed by bundling multiple fibers, or linear resin, and are flexible. The second members 7 are stretchable in only one direction. The plurality of second members 7 are arranged to overlap the first members 5. The plurality of second members 7 extend in a direction intersecting with the first members 5. The second members 7 are arranged across the upper forefoot portion 23, the upper midfoot portion 24, and the upper rearfoot portion 25. In each of the upper forefoot portion 23, the upper midfoot portion 24, and the upper rearfoot portion 25, the number of first members 5 is greater than the number of second members 7. The first member 5 and the second member 7 are disposed in a non-bonded state. The second member 7 may be formed by combining a plurality of materials.

[0074] The second members 7 are disposed on the lateral and medial sides of the throat portion 20b and the opening 20a. The second member 7 on the lateral side extends in the front-to-rear direction between the first joining region 61 and the third joining region 63, so as to traverse the upper forefoot portion 23, the upper midfoot portion 24, and the upper rearfoot portion 25. The second member 7 on the medial side extends in the front-to-rear direction between the second joining region 62 and the third joining region 63, so as to traverse the upper forefoot portion 23, the upper midfoot portion 24, and the upper rearfoot portion 25. Both ends of each of the multiple second members 7 are fixed ends 70 that are fixed to the joining region 6 of the upper main body 20G adjacent to the opening region 4. Hereinafter, when distinguishing between the fixed ends 70 of the second members 7, the fixed end 70 on one end of the second member 7 will be referred to as the fixed end 71, and the fixed end 70 on the other end of the second member 7 will be referred to as the fixed end 72. The fixed ends 71 ​​on one end side of the multiple second members 7 are lined up in the left-right direction. The fixed ends 72 on the other end side of the multiple second members 7 are lined up in the left-right direction. The order in which the fixed ends 71 ​​on one end side of the multiple second members 7 are lined up is the same as the order in which the fixed ends 72 on the other end side of the multiple second members 7 are lined up. The spacing between adjacent fixed ends 70 in the left-right direction may be different on one end side and the other end side, but in this embodiment, it is the same on one end side and the other end side. The multiple second members 7 are arranged parallel to each other.

[0075] This embodiment can achieve the same effects as the first embodiment. Furthermore, in this embodiment, a plurality of second members 7 extending in a direction intersecting the first members 5 are arranged in the opening region 4 in a non-bonded state. This reduces damage to the first members 5 and increases the variation in rigidity of the upper body 20G compared to a portion of the opening region 4 where only the first members 5 are arranged. Furthermore, since the first members 5 and the second members 7 are arranged in a non-bonded state and the number of first members 5 is greater than the number of second members 7, excessive increase in rigidity in the region where the second members 7 are arranged can be prevented. The location of the second members 7 is not limited to the illustrated example and may be changed as appropriate. The first members 5 and the second members 7 may intersect with each other. For example, the first members 5 may extend in the front-rear direction and the second members 7 may extend in the left-right direction.

[0076] (Embodiment 9) 18 is a development view of an upper 2H of a shoe according to a ninth embodiment of the present invention. The upper 2H according to the ninth embodiment differs from the upper 2 according to the first embodiment in that it includes a second member 8. In the ninth embodiment, parts that overlap with those in the first embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0077] In the opening region 4, a plurality of second members 8 are arranged so as to overlap the plurality of first members 5. The plurality of second members 8 are flexible sheet-like members. The second members 8 are formed from a single material. The material of the second members 8 is, for example, resin. The second members 8 are arranged in the upper midfoot portion 24. The number of second members 8 is not particularly limited, but in this embodiment, there are two. One second member 8 is arranged on the lateral side and one on the medial side of the throat portion 20b and the opening 20a. The first members 5 and the second members 8 are arranged in a non-bonded state. The second members 8 are fixed to the joining region 6 adjacent to the opening region 4. The second members 8 may be formed from a combination of multiple materials.

[0078] According to this embodiment, it is possible to achieve the same effects as in the first embodiment. Furthermore, according to this embodiment, the second member 8 is arranged in the opening region 4 so as to overlap with the first member 5. This makes it possible to suppress damage to the first member 5 and increase the variation in rigidity of the upper body 20H compared to a portion in the opening region 4 where only the first member 5 is arranged. Furthermore, since the first member 5 and the second member 8 are arranged in a non-bonded state, it is possible to suppress excessive increase in rigidity in the region where the second member 8 is arranged. Note that the location of the second member 8 is not limited to the example shown in the drawings and may be changed as appropriate.

[0079] The configurations shown in the above embodiments are examples of the content of the present invention, and can be combined with other known technologies, and parts of the configuration can be omitted or changed without departing from the gist of the present invention. The ranges of the opening regions 4-4E and the first members 5-5E are not limited to the examples shown in the above embodiments, and can be changed appropriately to suit the parts of the upper body 20-20E where it is desired to reduce the rigidity.

[0080] The upper sole portion 26 may be omitted from each of the above-described embodiments. Furthermore, while the first members 5-5F are formed from a single material in each of the above-described embodiments, the first members 5-5F may be formed from a combination of multiple materials. Furthermore, the first members 5-5F may be arranged in contact with each other or spaced apart from each other, as long as they are arranged in a non-bonded state. [Explanation of symbols]
