Description

The present invention relates to shoes.

2. Description of the Related Art Footwear having a tightening material capable of tightening an upper is known. For example, Patent Document 1 describes footwear having a band-shaped tightening material that tightens the upper. In this footwear, a groove or a through hole extending in the width direction is formed in the sole. The band-shaped tightening material is wound along the through-hole and the side surface of the foot, and is folded back diagonally up and down at the instep of the foot to form an engaging portion. The engaging portion is tightened by the shoelace. When worn in this manner, the tightening material presses the upper surface of the sole against the sole surface of the foot.

Japanese Patent Application Publication No. 08-131201 Utility model registration No. 3038156 JP2017-94125A Special Publication No. 2016-507296

The present inventors have obtained the following knowledge regarding the fit of shoes having a tightening material that tightens the upper. From the perspective of ensuring support when a high load is applied in the width direction, it is desirable that the change in foot position relative to the sole during high loads is small. However, in the footwear described in Patent Document 1, since the tightening material that tightens the upper can move within the groove of the sole, the tightening material moves and the position of the foot relative to the sole tends to change when the load is high.

If the tightening material is strongly tightened to suppress changes in foot position, the tightening force will be excessively large at the front of the shoe opening, making the shoe uncomfortable to wear. Furthermore, if the tightening force on the front side increases, the fit at the back of the shoe opening will deteriorate and the front-to-back balance will be lost. Based on these findings, the present inventors recognized that the footwear described in Patent Document 1 has room for improvement in terms of ensuring fit when a high load is applied.

The present invention has been made in view of these problems, and its purpose is to provide shoes with excellent front-to-back fit balance.

In order to solve the above problems, a shoe according to an aspect of the present invention includes a sole, an upper provided above the sole and having a collar, and a shoe fixed at a boundary between the upper and the sole in front of the collar. a first band extending diagonally upward from the first base end to the rear side of the shoe opening of the upper; and a second base end fixed to the boundary; A second band extends from the second base end to the front of the shoe opening, and contacts the first band with the upper at a portion where it intersects with the first band; and a tightening force is applied to the second band to tighten the upper. and a tightening portion.

Furthermore, any combination of the above, or mutual substitution of the components and expressions of the present invention among methods, apparatuses, programs, temporary or non-temporary storage media recording programs, systems, etc. This is effective as an aspect of the present invention.

According to the present invention, shoes with excellent front-to-back fit balance can be provided.

FIG. 2 is a plan view schematically showing the shoe 100. FIG. 3 is a side view schematically showing the shoe 100 as seen from the medial side.

The shoes 100 of this embodiment can be used, for example, as shoes for walking or running, or shoes for sports such as tennis or basketball. The shoe 100 includes a sole 10 and an upper 20 provided above the sole 10 and having a collar 20b. The sole 10 is a part for contacting the ground. The sole 10 may be composed of a plurality of members such as an outsole, a midsole, and an insole, or may be composed of a single material. The upper 20 is fixed above the sole 10 by adhesive or other means.

Hereinafter, when the shoe 100 is placed on a horizontal surface (hereinafter referred to as the "horizontal state"), the width direction of the upper 20 will be simply referred to as the "width direction", and the direction along the width direction center line La of the upper 20 will be referred to as "the width direction". The vertical direction is called the "front-back direction" and the vertical direction is called the "up-down direction." The width direction, the front-rear direction, and the up-down direction are orthogonal to each other.

Further, the direction from the heel to the toe side of the upper 20 along the widthwise center is referred to as the "front side" or "front", and the opposite direction is referred to as the "rear side" or "rear". Further, along the width direction, the direction from the outer foot side to the inner foot side is referred to as "medial" or "medial", and the opposite direction is referred to as "lateral" or "lateral". Further, along the vertical direction, the direction from the sole 10 to the upper 20 is referred to as the "upper side" or "upper side", and the opposite side is referred to as the "lower side" or "lower side".

Further, the inner side of the upper 20 from the center line La is called the inner foot part 28j, and the outer side from the center line La is called the outer foot part 28e. In addition, in the front-back direction, the part of the upper 20 corresponding to the metatarsal bones is called the midfoot part, the part of the upper 20 in front of the midfoot part is called the forefoot part, and the part of the upper 20 behind the midfoot part is called the forefoot part. is called the hindfoot. The forefoot generally corresponds to the phalanges, and the hindfoot generally corresponds to the tarsal bones.

As shown in FIGS. 1 to 3, the shoe 100 includes a first band 30, a second band 40, and a tightening part 60.

(1st band)
The first band 30 is a band-shaped member extending rearward from the first base end 32. The first band 30 may extend linearly, may extend in a convex upward curve, or may extend in a downward convex curve. The first base end portion 32 is fixed to the boundary portion Bp between the upper 20 and the sole 10 in front of the opening 20b. In addition, when it has several 1st bands 30, one 1st base end part 32 should just be fixed to this range, and the fixing position of the other 1st base end parts 32 is not limited. In this example, when the longitudinal length of the upper 20 is 100%, the first proximal end portion 32 is fixed at a position 15% to 35% from the toe. The first band 30 extends rearward from the first proximal end 32 along the outer foot 28e of the upper 20 to the first band contact area 24s of the heel 24 of the upper 20. The extended end 34 of the first band 30 contacts the first band contact area 24s. That is, the first band 30 extends diagonally upward from the first base end 32 to the rear side of the opening 20b of the upper 20.

In this embodiment, the inner foot portion 28j of the upper 20 also includes an inner foot extending from the proximal end portion fixed in front of the shoe opening 20b of the boundary portion Bp to the first band contact area 24s along the inner foot portion 28j. A side first band 30 is provided. In the following description, the first band 30 of the outer foot portion 28e may be referred to as an outer foot side first band. The extended end 34 of the first band 30 on the outer foot side is connected to the extended end 34 of the first band 30 on the inner foot side at the first band contact area 24s. In other words, the first band 30 is an integral band composed of the outer foot side first band 30 and the inner foot side first band 30 which are connected to each other. In this embodiment, the extended ends 34, 34 of the first band 30 on the outer foot side and the first band 30 on the inner foot side are fixed to the first band contact area 24s by adhesive, suture, etc.; however, these are not fixed. It doesn't have to be.

(band contact area)
In this embodiment, the first band contact area 24s is provided above the rearmost portion 24a of the heel portion 24. In this case, a forward diagonally downward force acts on the heel portion 24 due to the tension in the first band 30, and this force may deform the first band contact area 24s. From the viewpoint of smooth putting on and taking off, it is desirable that the deformation of the first band contact area 24s is small. Therefore, the first band contact area 24s of this embodiment is provided with a reinforcing structure 26 that is stronger than the surrounding area. As an example, the first band contact area 24s may be formed of a material that is thicker than the surrounding area, a material that is more rigid than the surrounding area, or a material that is harder than the surrounding area, or may be formed in multiple layers than the surrounding area. However, it may be formed by combining these configurations.

(2nd band)
The second band 40 is a band-shaped member that extends from the second base end 42 to the front of the shoe opening 20b. In this embodiment, the second base end portion 42 is fixed to the boundary portion Bp behind the first base end portion 32. When the front-back length of the upper 20 is 100%, the second base end portion 42 is fixed to the boundary portion Bp in the range of 35% to 90% from the toe in the front-back direction. The second band 40 extends forward and diagonally upward along the outer leg portion 28e of the upper 20 from the second base end portion 42 to the front region of the shoe opening 20b. That is, the tip end 44 of the second band 40 is located in front of the opening 20b.

In the present embodiment, the inner foot portion 28j of the upper 20 also includes a second inner foot band extending from the second base end 42 fixed to the boundary Bp along the inner foot portion 28j in front of the collar 20b. 40 are provided. In the following description, the lateral second band 40 may be referred to as the lateral second band 40. The distal end portion 44 of the second band 40 on the outer foot side and the distal end portion 44 of the second band 40 on the inner foot side are provided with an engaging portion 44b for engaging with the tightening portion 60. The engaging portions 44b on the outer foot side and the inner foot side are separated from each other in the width direction.

The tightening portion 60 applies a tightening force to the second band 40 in order to tighten the upper 20. In this embodiment, the tightening portion 60 is a shoelace, and the engaging portion 44b is a string hole through which the tightening portion 60 passes. By tightening the tightening portion 60, tension is applied to the engaging portions 44b on the outer foot side and the inner foot side in a direction in which they approach each other. At this time, tension from the second proximal end 42 toward the distal end 44 acts on the second band 40 on the outer foot side and the second band 40 on the inner foot side. By applying tension to the second band 40, the second band 40 comes into contact with the upper 20 and tightens the upper 20 toward the foot.

The intersection where the second band 40 intersects with the first band 30 will be explained. Hereinafter, among the intersections of the first band 30 and the second band 40, the second band 40 passes through the side opposite to the upper 20 of the first band 30 (hereinafter sometimes referred to as the "surface side") and intersects. The intersection where the second band 40 passes between the first band 30 and the upper 20 and intersects is indicated with the symbol R+number. The second band 40 brings the first band 30 into contact with the upper 20 at an intersection F where the second band 40 intersects with the first band 30. Note that when the intersection F+number is collectively referred to, it is referred to as the intersection F, and when the intersection R+number is collectively referred to, it is referred to as the intersection R.

With this configuration, the upper 20 is supported not only by the second band 40 but also by the first band 30, so that the front-rear balance of the fit of the upper 20 is improved.

A plurality of second bands 40 may be provided. In order to distinguish between the plurality of second bands 40, a hyphen and a number such as "-1" are added to the end of the code. In this embodiment, two second bands 40-1 and 40-2 are provided. The second band 40-2 is arranged substantially parallel to the second band 40-1 behind the second band 40-1. The second band 40-1 intersects the first band 30 at the intersection F1 of the first band 30. The second band 40-2 intersects the first band 30 at the intersection R1 of the first band 30. The first band 30 passes over the front surface side of the second band 40-2 at the intersection R1 to bring the second band 40-2 into contact with the upper 20.

In this case, since the first band and the second band press against each other at a plurality of positions, the tightening force can be applied appropriately. Further, the tightening range can be distributed back and forth.

As shown in FIG. 1, in this embodiment, the second band 40 passes on the front side of the first band 30 at the frontmost intersection F1 among the plurality of intersections. In this case, the second band 40 can press the first band 30 at the most forward intersection F1.

The first band 30 and the second band 40 (hereinafter collectively referred to as "band") may include a planar member having a predetermined width, for example, a band-like member. It's okay. There is no limit to the width of the band, but if the band is too small, it will be easily cut, and if it is too large, it will be difficult to design and manufacture. Regarding the band width, the inventor has obtained suggestions that a range of 3 mm or more and 30 mm or less is practical, a range of 5 mm or more and 20 mm or less is preferable, and a range of 7 mm or more and 14 mm or less is more preferable. The band of this embodiment is a band-shaped member with a width of 8 mm or more and 12 mm or less. In this case, compared to the case where the band is string-like, the tightening force can be dispersed, the upper 20 can fit better along the foot, and the tightening force is less likely to concentrate locally.

The band may be configured to include a string-like or thread-like member (hereinafter sometimes referred to as "string or thread"), or may be configured to include a plurality of string-like or thread-like members, The upper 20 may include a portion made up of a plurality of filaments extending along the surface of the upper 20. The first band 30 and the second band 40 may be made of members of the same shape, or may be made of members of different shapes. One of the first band 30 and the second band 40 includes a part made of a planar member having a predetermined width, and the other of the first band 30 and the second band 40 has a string-like or It may also include a portion made of a thread-like member.

The band of this embodiment is made of a material that is elastic enough to come into contact with the upper 20 when worn. In this case, the tightening force can be applied appropriately. For example, the band can be formed of a sheet-like material that has lower stretchability and elasticity than the upper 20. The band may be constructed from a variety of known materials. The band in this example is made of artificial leather. These descriptions regarding the morphological characteristics of the first and second bands 30, 40 also apply to the third band 50 and auxiliary band 70, which will be described later.

In this embodiment, the first band 30 and the second band 40 can take various forms. Modified examples of the band will be described below with reference to FIGS. 4 to 30. 4 to 30 are side views showing modified examples of the band, and correspond to FIG. 1.

A modification of the second band 40 will be explained. It is desirable that the tightening force of the band be distributed along the surface of the upper 20. For this reason, the shoe 100 may be provided with three or more second bands 40 on at least one of the inner foot side and the outer foot side. FIG. 4 is a side view showing an example in which three second bands 40-1, 40-2, and 40-3 are provided. FIG. 5 is a side view showing an example in which four second bands 40-1, 40-2, 40-3, and 40-4 are provided. FIG. 6 is a side view showing an example in which five second bands 40-1, 40-2, 40-3, 40-4, and 40-5 are provided.

The second band 40-3 is arranged behind the second band 40-2 and substantially parallel to the second band 40-2. The second band 40-4 is arranged behind the second band 40-3 and substantially parallel to the second band 40-3. The second band 40-5 is arranged behind the second band 40-4 and substantially parallel to the second band 40-4.

The second band 40-3 passes over the front side of the first band 30 at the intersection F2 and brings the first band 30 into contact with the upper 20. The second band 40-4 passes through the upper 20 side of the first band 30 at the intersection R2, is pushed by the first band 30, and comes into contact with the upper 20 side. In other words, the first band 30 passes over the surface side of the second band 40-4 at the intersection R2, bringing the second band 40-4 into contact with the upper 20. The second band 40-5 passes over the front side of the first band 30 at the intersection F3, and brings the first band 30 into contact with the upper 20. Although not limited to this, the intersections F and R in this example are arranged alternately. In this way, by forming a large number of intersections in the front and rear, the tightening force can be distributed in the front and rear.

Another modification of the second band 40 will be described. The plurality of second bands 40 may have an A-shape, a V-shape, a W-shape, an H-shape, or an M-shape, for example, on the proximal end side, the distal side, or at one or more locations between them. may be connected to each other. Moreover, the plurality of second bands 40 may be connected at the proximal end and the distal end, for example, like a number 0 shape. Further, the second band 40 may be branched into a plurality of branch parts at one or more locations on the proximal end side, the distal end side, or in between, and the plurality of branch parts may be located at positions away from the branch point. May be connected with

7 to 9 are side views showing examples in which parts of a plurality of second bands are connected to each other. The example of FIG. 7 includes two second bands 40-1, 40-2, and the two second bands 40-1, 40-2 are connected to each other on the distal side. In this example, the engaging parts 44b of the plurality of bands that engage with the tightening part 60 (shoe laces) are gathered together at the upper end side, and the two second bands 40-1 and 40-2 are arranged in an opposite V-shape. It is structured like this. In this case, the tightening force can be efficiently distributed in the front-rear direction. In other words, the tightening force can be distributed in multiple directions from one force point (the engaging portion 44b). The second band 40-1 forms an intersection F1 that passes through the front side of the first band 30, and the second band 40-2 forms an intersection R1 that passes through the upper 20 side of the first band 30. ing.

The example of FIG. 8 includes two second bands 40-1, 40-2, which are connected to each other at the proximal end. In this example, the two second bands 40-1 and 40-2 are configured in a V-shape by gathering the second base end portions 42 of the plurality of bands at the lower end side. In this case, the tightening force can be concentrated on areas that require lifting, such as the arch of the sole. In other words, the tightening forces from a plurality of force points (the engaging portions 44b) can be concentrated in one direction. The second band 40-1 forms an intersection F1 that passes through the front side of the first band 30, and the second band 40-2 forms an intersection R1 that passes through the upper 20 side of the first band 30. ing.

The example of FIG. 9 includes three second bands 40-1, 40-2, 40-3, and the two second bands 40-1, 40-2 are connected to each other proximally and distally. . In this example, the engaging portions 44b of the plurality of bands are gathered together at the upper end side, and the base end portions 42 of the plurality of bands are gathered together at the lower end side, forming an O-shape or a D-shape. In this case, the tightening force can be distributed from one force point in multiple directions and concentrated on areas that require lifting, such as the arch of the sole of the foot. The second band 40-1 forms an intersection F1 that passes through the front side of the first band 30, and the second band 40-2 forms an intersection R1 that passes through the upper 20 side of the first band 30. , the second band 40-3 forms an intersection F2 passing through the front side of the first band 30.

Furthermore, a modification of the second band 40 will be explained. The second band 40 and its modifications described above can be arbitrarily combined with other second bands 40 or modifications thereof. For example, the modified examples of the second band 40 shown in FIGS. 7 to 9 can be combined with other second bands 40. FIGS. 10 to 14 are side views showing modified examples of the second band 40 in which other second bands 40 are provided.

The example in FIG. 10 includes inverted V-shaped second bands 40-1, 40-2 and I-shaped second band 40-3, which are connected to each other at the distal end side. The second band 40-3 extends behind the second band 40-2 and substantially parallel to the second band 40-2. The second band 40-3 forms an intersection F2 passing through the front side of the first band 30.

The example in FIG. 11 includes inverted V-shaped second bands 40-1, 40-2 and I-shaped second bands 40-3, 40-4. The second band 40-3 extends behind the second band 40-2 and substantially parallel to the second band 40-2, and the second band 40-4 extends behind the second band 40-3 and extends substantially parallel to the second band 40-2. -3 and extends approximately parallel to it. The second band 40-3 forms an intersection F2 passing through the front side of the first band 30. The second band 40-4 forms an intersection R2 that passes through the first band 30 on the upper 20 side.

As in the examples shown in FIGS. 10 and 11, the combination of the inverted V-shaped second band and the I-shaped second band provides a stronger lace tightening effect in an appropriate range. For example, by arranging the I-shaped second band around the shoe opening 20b, a strong lacing effect can be provided around the ankle.

The example in FIG. 12 includes inverted V-shaped second bands 40-1 and 40-2, and inverted V-shaped second bands 40-3 and 40-4. That is, it includes a plurality of inverted V-shaped second bands. The second band 40-3 extends behind the second band 40-2 and substantially parallel to the second band 40-2. The second band 40-4 extends non-parallel to the second band 40-3 behind the second band 40-3. The second band 40-3 forms an intersection F2 passing through the front side of the first band 30. The second band 40-4 forms an intersection R2 that passes through the first band 30 on the upper 20 side. By providing a plurality of inverted V-shaped second bands, the tightening force can be distributed in stages in the front and rear directions.

The example in FIG. 13 includes inverted V-shaped second bands 40-1, 40-2 and I-shaped second band 40-3, which are connected to each other at the distal end side. The second band 40-3 forms an intersection P2 that passes through the upper 20 side of the second band 40-2. Further, the second band 40-3 forms an intersection F2 that passes through the front side of the first band 30. The intersection P2 is located below the intersection R1 and the intersection F2.

The example of FIG. 14 includes a plurality of inverted V-shaped second bands that intersect with each other. Specifically, it includes inverted V-shaped second bands 40-1, 40-2 and inverted V-shaped second bands 40-3, 40-4. The second bands 40-1, 40-2 and the second bands 40-3, 40-4 intersect the first band 30 as in the example of FIG. The second band 40-2 forms an intersection F2 that passes through the front side of the second band 40-3. The intersection F2 is located below the intersection R1 and the intersection F1.

As in the examples shown in FIGS. 13 and 14, the plurality of second bands 40 partially intersect with each other, thereby increasing the tightening force for the overlapping portions. In particular, by overlapping the inverted V-shaped second band 40-2 on the toe side on the surface side of the adjacent second band 40-3, the tightening force can be increased in that area.

Next, a modification of the first band 30 will be explained. A plurality of first bands 30 may be provided. 15 and 16 are side views showing an example in which a plurality of first bands 30 are provided. In this example, the plurality of first bands 30 are arranged one above the other. In this case, the tightening force can be distributed in the vertical direction. The examples in FIGS. 15 and 16 include a second band 40-1, a second band 40-2 placed behind it, a first band 30-1, and a first band 30- placed below it. Contains 2 and. The first bands 30-1 and 30-2 are arranged substantially parallel to each other, and each first band intersects each second band.

In the example of FIG. 15, the second band 40-1 forms intersections F1 and F2 that pass through the front surfaces of the first bands 30-1 and 30-2, and the second band 40-2 30-1 and 30-2 form intersections R1 and R2 that pass through the upper 20 side. That is, one second band passes only on the surface side of the plurality of first bands or only on the upper 20 side. In this case, the tightening force can be gradually distributed in the vertical direction.

In the example of FIG. 16, the second band 40-1 forms an intersection F1 that passes through the front side of the first band 30-1, and an intersection R1 that passes through the upper 20 side of the first band 30-2. is formed. Further, the second band 40-2 forms an intersection R2 that passes through the upper 20 side of the first band 30-1, and also forms an intersection F2 that passes through the front side of the first band 30-2. There is. That is, one second band alternately passes through the surface side of one first band and the upper 20 side of another first band. In this case, the first and second bands can be alternately crossed, and the crossing parts F and R can be arranged alternately in the front-rear direction and the up-down direction, so that the tightening force can be distributed even more gradually. can.

The plurality of first bands 30 may be connected to each other at one or more points on the proximal end side, the distal side, or in between. Further, the first band 30 may be branched into a plurality of branch portions at one or more locations on the proximal end side, the distal end side, or in between, and the plurality of branch portions may be located away from the branch point. May be connected with 17 to 19 are side views showing examples in which a plurality of first bands 30 are connected to each other on the proximal end side, the distal side, or in the middle thereof.

The examples in FIGS. 17 to 19 include a second band 40-1 and a second band 40-2 arranged behind it, and a first band 30-1 and a first band 30-2 arranged below it. Contains. In the examples of FIGS. 17 to 19, the second band 40-1 forms intersections F1 and F2 that pass through the front surfaces of the first bands 30-1 and 30-2, and the second band 40-2 Intersections R1 and R2 are formed that pass through the upper 20 side of the first bands 30-1 and 30-2. In the examples shown in FIGS. 17 to 19, the first and second bands may alternately intersect as in the example shown in FIG.

In the example of FIG. 17, the first bands 30-1 and 30-2 have their respective base end portions 32 fixed to the boundary portion Bp at a distance from each other in the front and back, and the extending ends 34 are connected to each other.

Next, a modification of the band form will be described. 20 to 27 are side views showing modified examples of the band form.

In the example of FIG. 20, the first band 30 is formed into a string shape. All of the first bands 30 do not need to have the same shape, and a part of the band may be a band shape and another part may have another shape such as a string shape.

In the example of FIG. 21, the first band 30 is formed into a wide belt shape. The width of the first band 30 may be 1.5 times or more or twice the width of the second band. All of the first bands 30 do not need to have the same width; some of the bands may be wide and other parts may have different widths.

In the example of FIG. 22, the second bands 40-1 and 40-2 are formed into string shapes. All of the second bands 40 do not need to have the same shape, and some of the bands may be belt-like and other parts may have another shape, such as a string-like shape.

In the example of FIG. 23, the second band 40 is formed into a wide belt shape. All of the second bands 40 do not need to have the same width; some of the bands may be wide and other parts may have different widths.

As shown in FIGS. 20 to 23, the tightening force can be adjusted by making the first band 30 and the second band 40 thinner or thicker. The fit along the foot can be improved by using thin bands or strings in areas where the curvature is small. In cases where lateral holdability is required, such as in court sports, the use of a thick band can improve the holdability during braking situations.

In the examples shown in FIGS. 24 and 25, the first band 30 is composed of a plurality of string-like or thread-like members. The first band 30 includes a plurality of bundled filaments extending along the surface of the upper 20. In the example of FIG. 24, the plurality of filaments pass on the upper 20 side of the second band 40-1 at the intersection F1, and pass on the front side of the second band 40-2 at the intersection R1. Since the first band 30 is partially composed of thin strings or threads, a better fit can be achieved along the foot.

In the example of FIG. 25, the plurality of filaments include those that pass on the upper 20 side of the second band 40-1 and those that pass on the front side of the second band 40-1 at the intersections S1 and S2. In addition, each filament body may pass alternately through the surface side and the upper side of the plurality of second bands 40. By alternately intersecting the second band 40 with the parts made of thin strings or threads, the tightening force can be distributed in a more gradual manner.

In the examples shown in FIGS. 26 and 27, the second band 40 is composed of a plurality of string-like or thread-like members. The second band 40 is composed of a plurality of filaments arranged along the surface of the upper 20. In the example of FIG. 26, the plurality of filaments pass on the surface side of the first band 30 at the intersection S1, and pass on the upper 20 side of the first band 30 at the intersection S2. By partially forming the second band 40 with thin strings or threads, a better fit along the foot can be achieved.

In the example of FIG. 27, the plurality of filaments include those that pass on the upper 20 side of the first band 30 and those that pass on the surface side at the intersections S1 and S2. Note that the thread bodies passing through the upper 20 side and the thread bodies passing through the front side may be arranged alternately. Since the first band intersects with the first band in such a manner that the parts partially made of thin strings or threads intersect with each other, the efficiency of transmitting the tightening force to the first band 30 can be further improved.

Furthermore, a modification of the first band 30 will be explained. 28 and 29 are side views showing modified examples of the first band 30. FIG.

In the example of FIG. 28, the first band 30 is provided with an engaging portion 36b for engaging with the tightening portion 60. By having the engaging portion 36b, the tightening force in the front-rear direction can be increased. The engaging portion 36b in this example is provided at the protruding end of the protruding portion 36 that protrudes upward from the first band 30. The engaging portion 36b is a lace hole through which the tightening portion 60 (shoelace) passes, and has the same configuration as the engaging portion 44b. One or more engaging portions 36b may be provided, and in this example, two engaging portions 36b are provided, one in front of the second band 40-1 and the other in the rear of the second band 40-2.

Although the above description shows an example in which the first band 30 is provided in a curved shape, the first band 30 may be stretched in a straight line. In the example of FIG. 29, the first band 30 extends linearly. By forming the first band 30 in a straight line, the tightening force can be transmitted in the front-rear direction more efficiently. It is desirable that the base end 32 of the first band 30 be fixed to the boundary Bp at a position avoiding the vicinity of the MP joint.
