FIELD
The present invention relates to a shoe including an upper and a sole.
BACKGROUND
Conventionally, a shoe including an upper and a sole positioned below the upper is known. When a wearer wears the shoe, a gap tends to occur between the shoe and both sides of the heel position of the foot along the foot width direction. When a gap occurs between the heel position and the shoe, the heel position is displaced in the shoe. Therefore, it is necessary to prevent a gap between the heel position and the shoe from occurring.
Conventionally, as in Patent Literature 1, a technique has been developed in which a band member extending from a lower end portion of a medial-foot-side wall portion of an upper to an upper end portion of a lateral-foot-side wall portion through a bottom wall portion is disposed inside the upper, and by pulling the band member, a portion of the band member disposed over the lateral-foot-side wall portion and the bottom wall portion is lifted toward the medial foot side and obliquely upward to prevent the calcaneus from falling outward. In addition, as in Patent Literature 1, a technique has been developed in which a band member extending from a lower end portion of a lateral-foot-side wall portion of an upper to an upper end portion of a medial-foot-side wall portion through a bottom wall portion is disposed inside the upper, and by pulling the band member, a portion of the band member disposed over the medial-foot-side wall portion and the bottom wall portion is lifted toward the lateral foot side and obliquely upward to prevent the calcaneus from falling inward. In other words, a technique of lifting a heel position from one side of the heel position along the foot width direction has been developed. However, a technique for preventing a gap between the shoe and both sides of the heel position along the foot width direction has not been developed.

DESCRIPTION OF EMBODIMENTS
Hereinafter, embodiments of a shoe according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by the embodiments. In the following description, the same portions are denoted by the same reference signs, and redundant description will be omitted.
First Embodiment
FIG. 1 is a plan view schematically illustrating a shoe 1 according to a first embodiment of the present invention overlapped on a skeleton model of a foot. In the drawings including FIG. 1, only the shoe 1 for a left foot is illustrated. Since the shoe 1 has a left-right symmetrical structure for a left foot and a right foot, only the shoe 1 for a left foot is described in the present embodiment, and the description of the shoe 1 for a right foot is omitted. In the following description, a direction in which a shoe center axis C, which is a perpendicular line passing through the center of the shoe 1 in a plan view of the shoe 1, extends is referred to as a fore-rear direction, and a direction orthogonal to the fore-rear direction in a plan view of the shoe 1 is referred to as a foot width direction.
In addition, of the fore-rear direction, a direction directed from the end on the side where the shoe 1 supporting the rear foot position of a foot is positioned toward the end on the side where the shoe 1 supporting the fore foot position of the foot is positioned is referred to as a fore side, and of the fore-rear direction, a direction directed from the end on the side where the shoe 1 supporting the fore foot position of the foot is positioned toward the end on the side where the shoe 1 supporting the rear foot position of the foot is positioned is referred to as a rear side.
In addition, a median side of a foot in the anatomical position is referred to as a medial foot side, and the side opposite to the median side of the foot in the anatomical position is referred to as a lateral foot side. That is, the side closer to the median line in the anatomical position is referred to as the medial foot side, and the side farther from the median line in the anatomical position is referred to as the lateral foot side.
In addition, a vertical direction means a direction orthogonal to both the fore-rear direction and the foot width direction unless otherwise specified.
A foot of a human is mainly constituted by a cuneiform Ba, a cuboid Bb, a navicular Bc, a talus Bd, a calcaneus Be, a metatarsal Bf, and a phalange Bg. The foot joints include an MP joint Ja, a Lisfran joint Jb, and a Chopart joint Jc. The Chopart joint Jc includes a calcaneocuboid joint Jc1 constituted by the cuboid Bb and the calcaneus Be, and a talonavicular joint Jc2 constituted by the navicular Bc and the talus Bd.
A fore foot position of the foot refers to a part positioned anterior to the MP joint Ja. A mid-foot position of the foot refers to a part from the MP joint Ja to the Chopart joint Jc. A rear foot position of the foot refers to a part positioned posterior to the Chopart joint Jc. A medial longitudinal arch Ar of the foot refers to a part from the calcaneus Be through the talus Bd, the navicular Bc, and the medial cuneiform Ba to the hallucal area of a first metatarsal Bf1 on the medial foot side of the foot.
An upper 2 includes an upper fore foot portion R1 which is a portion covering a fore foot position of a foot of a wearer with a standard body shape, an upper mid-foot portion R2 which is a portion covering a mid-foot of a foot of a wearer with a standard body shape, and an upper rear foot portion R3 which is a portion covering a heel position of a foot of a wearer with a standard body shape. The upper fore foot portion R1, the upper mid-foot portion R2, and the upper rear foot portion R3 are connected in this order in the fore-rear direction from the fore side of the upper 2.
A line along the foot width direction passing through a position corresponding to about 25% to 50% of the dimension of the upper 2 from the fore end of the upper 2 in the fore-rear direction is defined as a first boundary line S1, and a line along the foot width direction passing through a position corresponding to about 55% to 80% of the dimension of the upper 2 from the fore end of the upper 2 in the fore-rear direction is defined as a second boundary line S2. The first boundary line S1 is a line roughly along the MP joint Ja of a wearer with a standard body shape. The second boundary line S2 is a line roughly along the Chopart joint Jc of a wearer with a standard body shape. The upper fore foot portion R1 is positioned in front of the first boundary line S1. The upper mid-foot portion R2 is positioned between the first boundary line S1 and the second boundary line S2. The upper rear foot portion R3 is positioned behind the second boundary line S2.
FIG. 2 is a perspective view illustrating the shoe 1 according to the first embodiment. The shoe 1 is used as, for example, running shoes, other sports shoes, walking shoes, and climbing shoes. The shoe 1 includes the upper 2, a sole 3, a pair of panel members 4, and a shoelace 5.
The upper 2 is positioned above the sole 3. The upper 2 includes an upper body 20 and a shoe tongue 21.
The upper body 20 covers a part on the instep side of a foot. At the upper portion of the upper body 20, a foot insertion opening 20a for inserting a foot of a wearer and an opening 20b communicating with the foot insertion opening 20a and extending from the foot insertion opening 20a to the fore side are disposed. On both side edges of the opening 20b in the foot width direction, a first string passing portion 22 and a second string passing portion 23, which are separated from each other in the fore-rear direction, are disposed. The structure of the first string passing portion 22 is not particularly limited as long as the shoelace 5 can be passed therethrough, but the first string passing portion 22 in the present embodiment is a through hole that passes through the upper body 20 in the vertical direction. At the upper end portion of each panel member 4, one second string passing portion 23 is disposed. Details of the second string passing portion 23 will be described later. On each side of the upper body 20 in the foot width direction with the opening 20b sandwiched therebetween, a side wall portion 24 extending in the vertical direction is disposed. In the present embodiment, the upper 2 including the shoe tongue 21 and the shoelace 5 is described as an example, but the upper 2 may have a monosock structure in which a portion corresponding to the shoe tongue 21 is integrated with an ankle portion of the upper body 20.
The shoe tongue 21 is a member for protecting the instep of a wearer. The shoe tongue 21 covers the opening 20b inside the upper body 20. The shoe tongue 21 is fixed to the upper body 20 by stitching, welding, bonding, or a combination thereof. As the material of the upper body 20 and the shoe tongue 21, woven fabric, knitted fabric, synthetic leather, or resin is used, for example. In particular, in the shoe 1 required to have air permeability and lightweight property, a double raschel warp knitted fabric knitted with polyester yarn is preferably used as the material of the upper body 20 and the shoe tongue 21. Note that the material of the upper body 20 and the shoe tongue 21 is not limited to those exemplified.
The sole 3 is positioned below the upper 2. The sole 3 covers the sole of a wearer. The sole 3 includes an outsole 30 and a midsole 31. The sole 3 is fixed to the upper body 20 by stitching, welding, bonding, or a combination thereof. The lower surface of the outsole 30 serves as a ground contact surface 30a to be contacted on the ground. The midsole 31 is positioned on the upper surface of the outsole 30 and has a cushioning property. Note that the outsole 30 may be integrated with the midsole 31. The outsole 30 integrated with the midsole 31 is also referred to as a “unisole”.
FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2. In FIG. 3, the panel members 4 are each illustrated as one member for easy understanding, but the panel member 4 is actually formed of a plurality of members as described later. The sole 3 includes an inner sole 32 and an insole 33. The inner sole 32 covers the lower opening of the upper body 20. The inner sole 32 is fixed to the lower end portion of the upper body 20 by stitching. The inner sole 32 is further fixed to the upper surface of the midsole 31 by bonding or welding. The inner sole 32 is disposed on the midsole 31 with the outsole 30 sandwiched therebetween inside the upper body 20. The insole 33 is disposed on the outsole 30 with the inner sole 32 and the midsole 31 sandwiched therebetween. The sole 3 may have a structure in which the inner sole 32 is omitted.
As illustrated in FIG. 1, the panel members 4 are each disposed on the lateral foot side and the medial foot side inside the upper rear foot portion R3. The panel members 4 are each disposed on the lateral foot side and the medial foot side of the heel position of a foot F. The panel member 4 on the lateral foot side is disposed behind a fifth metatarsal tuberosity Bh of the wearer. The panel member 4 on the medial foot side is disposed at a position corresponding to a part of the medial longitudinal arch Ar of the wearer in the fore-rear direction. The fore end portion of the panel member 4 on the medial foot side and the fore end portion of the panel member 4 on the lateral foot side correspond in position to each other in the fore-rear direction. The rear end portion of the panel member 4 on the medial foot side and the rear end portion of the panel member 4 on the lateral foot side correspond in position to each other in the fore-rear direction. The panel member 4 on the medial foot side and the panel member 4 on the lateral foot side are symmetrical in shape.
As illustrated in FIG. 2, each panel member 4 extends obliquely upward and forward from the lower end portion of the upper body 20. The lower end portion of each panel member 4 is disposed at a position corresponding to the foot insertion opening 20a in the fore-rear direction. The upper end portion of each panel member 4 is disposed at a position corresponding to the boundary portion between the side edge of the opening 20b and the foot insertion opening 20a in the fore-rear direction. The upper end portion of each panel member 4 is fixed to the upper body 20 behind the rearmost first string passing portion 22. The shape of each panel member 4 is a triangular shape in which the width in the fore-rear direction decreases from the lower end portion toward the upper end portion. Specifically, the shape of each panel member 4 is a triangular shape with the second string passing portion 23 as an apex at the uppermost position. The fore end portion and the rear end portion of each panel member 4 extend linearly toward the obliquely upward and forward.
As illustrated in FIG. 3, the lower end portion of each panel member 4 is fixed to the lower end portion of the upper body 20 by a stitch SE in the present embodiment, but is only required to be fixed to the lower end portion side of the upper 2 or the sole 3. Here, the line connecting the outermost portion of the upper 2 in plan view of the shoe 1 is referred to as an “R-R line”. In the present specification, the lower end portion side of the upper 2 means a portion of the upper 2 below the R-R line when the shoe 1 is viewed from the side. When the panel members 4 are fixed to the sole 3, the lower end portions of the panel members 4 are preferably fixed to the inner sole 32 or the insole 33 of the sole 3. In other words, the lower end portions of the panel members 4 may be fixed to any one of the lower end portion side of the upper 2, the inner sole 32, and the insole 33 by the stitch SE or the like.
The second string passing portion 23 is disposed on the upper end portion of each panel member 4. The upper end portion of the panel member 4 passes above the side wall portion 24 of the upper body 20 from the inside toward the outside of the upper body 20 and is folded downward. Then, the portion of the panel member 4 passing above the side wall portion 24 and positioned outside the upper body 20 and the side wall portion 24 are fixed to each other by the stitch SE to form the loop-shaped second string passing portion 23.
FIG. 4 is a side view of the panel member 4 according to the first embodiment when viewed from the inside of the upper 2. FIG. 5 is a cross-sectional view taken along line V-V in FIG. 4. As illustrated in FIG. 5, each panel member 4 includes an inner panel member 40 capable of being in contact with the foot F of the wearer, and an outer panel member 41 disposed on the side opposite to the foot F of the wearer with the inner panel member 40 sandwiched therebetween. As the material of the inner panel member 40 and the outer panel member 41, a material that hardly stretch when the panel member 4 is pulled up, that is, a material having low stretchability is preferably used. Such a material having low stretchability is, for example, a suede-like artificial leather. The thickness of the inner panel member 40 capable of being in contact with the foot F is preferably thicker than the thickness of the outer panel member 41 that is not in contact with the foot F.
A certain region from the upper end portions toward the lower end portions of the inner panel member 40 and the outer panel member 41 is a bonded region 45 bonded to each other by a bonding agent 42. The bonding agent 42 is, for example, hot melt. Of the inner panel member 40 and the outer panel member 41, a region below the bonded region 45 is a stitched region 46 stitched to each other. The stitched region 46 is a region that is easily brought into contact with the foot F of the wearer as compared with the bonded region 45. The hardness of the bonded region 45 is higher than the hardness of the stitched region 46. FIG. 4 illustrates a stitched portion 47 in which the inner panel member 40 and the outer panel member 41 are stitched. The stitched portion 47 is disposed over the fore end portion, the lower end portion, the rear end portion, and a portion between the fore end portion and the rear end portion of the inner panel member 40 and the outer panel member 41.
As illustrated in FIG. 5, each panel member 4 includes a cushioning member 43 disposed to be capable of being in contact the foot F of the wearer and formed of a material softer than the inner panel member 40 and the outer panel member 41. The cushioning member 43 protrudes from the inner panel member 40 toward the foot F of the wearer. The cushioning member 43 is disposed near the center of the panel member 4 in the vertical direction. An attaching hole 40a is disposed in a portion of the inner panel member 40 corresponding to the cushioning member 43. The cushioning member 43 is disposed in the attaching hole 40a. As illustrated in FIG. 4, the shape of the cushioning member 43 is substantially similar to the shape of the panel member 4, and is a triangular shape in which the width in the fore-rear direction decreases from the lower end portion toward the upper end portion. Specifically, the shape of the cushioning member 43 is a triangular shape with one vertex positioned above the others. A part of the inner panel member 40 and the outer panel member 41 is disposed on both front and rear sides with the cushioning member 43 sandwiched therebetween.
As illustrated in FIG. 5, each panel member 4 includes a protective cover 44 covering the cushioning member 43 from the inner side of the upper body 20. As the material of the protective cover 44, a material that is easily extended so as not to hinder the bulge of the cushioning member 43, that is, a material having high stretchability is preferably used. Such a material having high stretchability is, for example, a mesh material. The cushioning member 43 is disposed between the protective cover 44 and the outer panel member 41. The circumferential edge of the protective cover 44 is sandwiched between the inner panel member 40 and the outer panel member 41 and fixed by stitching. FIG. 4 illustrates a stitched portion 48 in which the protective cover 44, the inner panel member 40, and the outer panel member 41 are stitched. The stitched portion 48 is disposed along the outer circumference of the cushioning member 43. FIG. 6 is a lateral-foot-side side view schematically illustrating a state in which the panel member 4 is overlapped on the foot F. As illustrated in FIG. 6, the cushioning member 43 of the panel member 4 on the lateral foot side is disposed to be capable of being in contact with an area below a lateral malleolus D of the wearer.
FIG. 7 is a plan view illustrating the panel member 4 and the surroundings of the panel member 4 according to the first embodiment. As illustrated in FIG. 7, the shoe 1 includes a lining member 6 disposed between the rear end portions of the pair of panel members 4 inside the upper rear foot portion R3. The rear end portion of each panel member 4 and the lining member 6 are stitched to be flush with each other. In the following description, a portion in which each panel member 4 and the lining member 6 are stitched is referred to as a stitched portion 9.
FIG. 8 is a view of the panel member 4, the lining member 6, and a heel counter 7 according to the first embodiment when viewed from the inner side of the upper 2. The shoe 1 includes the heel counter 7 disposed on the side opposite to the foot F of the wearer with each panel member 4 and the lining member 6 sandwiched therebetween. An upper end portion 9a of the stitched portion 9 of each panel member 4 and the lining member 6 is positioned above an upper end portion 7a of the heel counter 7 at least at the position where the stitched portion 9 is disposed.
FIG. 9 is a perspective view illustrating the panel member 4 and a reinforcing member 8 according to the first embodiment. The reinforcing member 8 having non-stretchability is disposed on a portion of the upper body 20 overlapping each panel member 4 in the foot width direction of the shoe 1. The reinforcing member 8 serves to prevent the upper body 20 from stretching when the panel member 4 is pulled up. As the material of the reinforcing member 8, a suede-like artificial leather is used, for example. A middle portion of the panel member 4 in the vertical direction is not fixed to the upper body 20 and capable of being separated from the upper body 20.
As illustrated in FIG. 2, the shoelace 5 is a string-like member that is alternately passed through the first string passing portion 22 and the second string passing portion 23 disposed on one side edge of the opening 20b in the foot width direction, and the first string passing portion 22 and the second string passing portion 23 disposed on the other side edge in the foot width direction. The shoelace 5 is detachably attached to the upper body 20. The shoelace 5 is a pulling member that is connected to the upper end portion of each panel member 4 via the second string passing portion 23 and capable of applying a force for pulling up each panel member 4 to each panel member 4 in a direction toward the upper mid-foot portion R2 and in a direction away from the sole 3. In other words, the shoelace 5 is capable of applying a force for pulling up each panel member 4 obliquely upward and forward to each panel member 4.
FIG. 10 is a cross-sectional view illustrating a state after each panel member 4 is pulled up from the state illustrated in FIG. 3. In FIG. 10, the panel member 4 is illustrated as one member for easy understanding. As illustrated in FIG. 10, when the shoelace 5 is tightened, the second string passing portion 23 of each panel member 4 is pulled obliquely upward and forward, and each panel member 4 is pulled up in the direction toward the upper mid-foot portion R2 and in the direction away from the sole 3. As a result, each panel member 4 is tensioned to decrease the distance between the pair of panel members 4 in the foot width direction, which causes the panel member 4 on the lateral foot side to pull up the heel position of the foot F from the lateral foot side and the lower side and the panel member 4 on the medial foot side to pull up the heel position of the foot F from the medial foot side and the lower side.
Next, effects of the shoe 1 according to the present embodiment are described.
In the present embodiment, as illustrated in FIG. 2, the shoe 1 includes the upper 2 in which the upper mid-foot portion R2 covering the upper mid-foot position of the foot F of the wearer and the upper rear foot portion R3 covering the heel position of the foot F are disposed, and the sole 3 positioned below the upper 2. The shoe 1 also includes the pair of panel members 4 each disposed on the lateral foot side and the medial foot side inside the upper rear foot portion R3 with the lower end portion fixed to the lower end portion side of the upper 2 or the sole 3, and the shoelace 5 connected to the upper end portion of the panel member 4 and capable of applying a force for pulling up the panel member 4 to the panel member 4 in the direction toward the upper mid-foot portion R2 and in the direction away from the sole 3. With these structures, since each panel member 4 is pulled up in the direction toward the upper mid-foot portion R2 and in the direction away from the sole 3 by tightening the shoelace 5, each panel member 4 is tensioned to decrease the distance between the pair of panel members 4 in the foot width direction, and it is possible to pull up the heel position from both sides in the foot width direction and from the lower side. As a result, the panel members 4 are brought into close contact with both sides of the heel position along the foot width direction so as to wrap the heel position with the pair of panel members 4 from both sides in the foot width direction and from the lower side, and it is possible to prevent the positional displacement of the heel position in the shoe 1 and improve the fit of the shoe 1 with the heel position. In particular, since an area below the malleolus of the wearer is an area in which a gap tends to occur between the foot F and the shoe 1, the panel members 4 are brought into close contact with the area to fill the gap, and it is possible to improve the fit of the shoe 1 with the heel position.
In the present embodiment, as illustrated in FIG. 3, the second string passing portion 23 is disposed on the upper end portion of each panel member 4, and the pulling member is the shoelace 5 passed through the second string passing portion 23. With this structure, since the panel members 4 can be directly pulled up by tightening the shoelace 5, it is possible to further improve the fit of the shoe 1 with the heel position. In addition, by tightening the shoelace 5, the upper body 20 can be tightened and the panel member 4 can be pulled up at the same time, and it is possible to reduce the burden on the wearer.
In the present embodiment, as illustrated in FIG. 5, each panel member 4 includes the inner panel member 40 capable of being in contact with the foot F of the wearer, and the outer panel member 41 disposed on the side opposite to the foot F of the wearer with the inner panel member 40 sandwiched therebetween. In addition, a certain region from the upper end portions toward the lower end portions of the inner panel member 40 and the outer panel member 41 is the bonded region 45 bonded to each other, and a region of the inner panel member 40 and the outer panel member 41 below the bonded region 45 is the stitched region 46 stitched to each other. With these structures, by partially changing the fixing method between the inner panel member 40 and the outer panel member 41, it is possible to change the hardness of each panel member 4. In addition, by disposing the bonded region 45 harder than the stitched region 46 in the certain region from the upper end portions toward the lower end portions of the inner panel member 40 and the outer panel member 41, the upper end portion of the inner panel member 40 and the outer panel member 41 including the second string passing portion 23 becomes hard, and it is possible to improve the effect of pulling up the panel member 4 by the shoelace 5 and the strength of the second string passing portion 23 against the pulling load. On the other hand, by disposing the stitched region 46 softer than the bonded region 45 in the region of the inner panel member 40 and the outer panel member 41 below the bonded region 45, the region of the panel member 4 that is easily brought into direct contact with the foot F becomes soft, and it is possible to improve the contact of the panel member 4 with the foot. The inner panel member 40 and the outer panel member 41 are overlapped to form each panel member 4, whereby the stretch of the panel member 4 is prevented when the panel member 4 is pulled up, and it is possible to pull up the panel member 4 to further improve the fit of the shoe 1 with the heel position.
In the present embodiment, as illustrated in FIG. 5, each panel member 4 includes the cushioning member 43 disposed to be capable of being in contact with the foot F of the wearer and formed of a material softer than the inner panel member 40 and the outer panel member 41. With this structure, it is possible to further improve the contact of the panel member 4 with the foot.
The area below the lateral malleolus D of the wearer illustrated in FIG. 6 is an area in which a gap tends to occur between the foot F and the shoe 1. In this regard, in the present embodiment, the cushioning member 43 of the panel member 4 on the lateral foot side protrudes from the inner panel member 40 toward the foot F of the wearer and is disposed to be capable of being in contact with the area below the lateral malleolus D of the wearer. With this structure, when the panel member 4 is pulled up, the cushioning member 43 can be brought into contact with the area below the lateral malleolus D to fill the gap, and it is possible to further improve the fit of the shoe 1 with the heel position.
In the present embodiment, as illustrated in FIG. 7, the shoe 1 includes the lining member 6 disposed between the rear end portions of the pair of panel members 4 inside the upper rear foot portion R3, and the rear end portion of each panel member 4 and the lining member 6 are stitched to be flush with each other. With this structure, since there is no difference between the rear end portion of each panel member 4 and the lining member 6, it is possible to prevent the contact due to the difference with the foot.
In the present embodiment, as illustrated in FIG. 8, the shoe 1 includes the heel counter 7 disposed on the side opposite to the foot F of the wearer with each panel member 4 and the lining member 6 sandwiched therebetween, and the upper end portion 9a of the stitched portion 9 of the panel member 4 and the lining member 6 is positioned above the upper end portion 7a of the heel counter 7 at least at the position where the stitched portion 9 is disposed. With this structure, since the heel counter 7 is not exposed to the inside of the upper 2 from between the panel member 4 and the lining member 6, it is possible to prevent the contact due to the exposure of the heel counter 7 with the foot. Note that, the upper end portion 9a of the stitched portion 9 is positioned above the upper end portion 7a of the heel counter 7 at least at the position where the stitched portion 9 is disposed, whereby it is possible to prevent the reduction in the movable range of the panel member 4 due to being stitched to the lining member 6. That is, in the present embodiment, it is possible to prevent the contact due to the exposure of the heel counter 7 with the foot while securing the effect of pulling up the panel member 4 to improve the fit of the shoe 1 with the heel position.
In the present embodiment, as illustrated in FIG. 1, the panel member 4 on the lateral foot side is disposed behind the fifth metatarsal tuberosity Bh of the wearer, whereby it is possible to prevent the contact of the panel member 4 on the lateral foot side with the fifth metatarsal tuberosity Bh. In addition, the fore end portion of the panel member 4 on the medial foot side and the fore end portion of the panel member 4 on the lateral foot side correspond in position to each other in the fore-rear direction, whereby it is possible to reduce the range in which the panel member 4 on the medial foot side is in contact with the medial longitudinal arch Ar and to reduce the contact of the panel member 4 on the medial foot side with the medial longitudinal arch Ar when the medial longitudinal arch Ar collapses.
In the present embodiment, as illustrated in FIG. 2, the shape of each panel member 4 is a shape in which the width in the fore-rear direction decreases from the lower end portion toward the upper end portion. With this structure, the tension applied to the panel member 4 when the shoelace 5 is tightened is easily transmitted from the lower end portion to the upper end portion of the panel member 4. Therefore, it is possible to pull up the panel member 4 to further improve the fit of the shoe 1 with the heel position.
Since the second string passing portion 23 at the upper end portion of the panel member 4 illustrated in FIG. 3 is stitched to the upper body 20, the upper body 20 is also slightly pulled up when the panel member 4 is pulled up. In this regard, in the present embodiment, as illustrated in FIG. 9, the reinforcing member 8 having non-stretchability is disposed on the portion of the upper 2 overlapping the panel member 4 in the foot width direction of the shoe 1, whereby it is possible to prevent the upper body 20 from being pulled up when the panel member 4 is pulled up. As a result, the panel member 4 can be easily moved relative to the upper body 20, and it is possible to pull up the panel member 4 to improve the fit of the shoe 1 with the heel position.
In the present embodiment, as illustrated in FIG. 9, the middle portion of the panel member 4 in the vertical direction can be separated from the upper body 20. With this structure, the panel member 4 can be easily moved relative to the upper body 20 when the shoelace 5 is tightened, and it is possible to pull up the panel member 4 to further improve the fit of the shoe 1 with the heel position.
In the present embodiment, a material having low stretchability is used for the inner panel member 40 and the outer panel member 41 illustrated in FIG. 5. With this structure, the stretching of the inner panel member 40 and the outer panel member 41 when the inner panel member 40 and the outer panel member 41 are pulled up is prevented, and it is possible to pull up the panel member 4 to further improve the fit of the shoe 1 with the heel position.
Note that, the pair of panel members 4 illustrated in FIG. 1 has a left-right symmetrical shape in the present embodiment, but may have a left-right asymmetric shape. For example, the panel member 4 on the medial foot side illustrated in FIG. 1 may be extended forward from the panel member 4 on the lateral foot side, and the panel member 4 on the medial foot side may be disposed at a position corresponding to the entire medial longitudinal arch Ar of the wearer in the fore-rear direction. In addition, the shape of each panel member 4 is preferably a shape in which the width in the fore-rear direction decreases from the lower end portion toward the upper end portion, but is not limited to the illustrated example.
In the present embodiment, the second string passing portion 23 illustrated in FIG. 3 is formed by folding back the upper end portion of the panel member 4 and stitching it to the upper body 20, but may be formed by fixing a loop-shaped member separate from the panel member 4 to the upper end portion of the panel member 4.
Each panel member 4 illustrated in FIG. 5 is formed by overlapping two members although there is an exception in part in the present embodiment, but may be formed of one member or may be formed by overlapping a plurality of members other than two members. In addition, each panel member 4 includes the bonded region 45 and the stitched region 46 in the present embodiment, but the bonded region 45 may be disposed over the entire region of the panel member 4. Each panel member 4 includes the cushioning member 43 in the present embodiment, but the cushioning member 43 may not be disposed or may be disposed on any one of the panel members 4 on the lateral foot side and the medial foot side.
The rear end portion of each panel member 4 and the lining member 6 illustrated in FIG. 8 are stitched in the present embodiment, but may not be stitched as long as the panel member 4 can be formed of a thin material that the difference between the rear end portion of each panel member 4 and the lining member 6 is not felt. If the rear end portion of each panel member 4 and the lining member 6 are not stitched in this manner, the reduction in the movable range of the panel member 4 due to being stitched to the lining member 6 does not occur, and it is possible to pull up the panel member 4 to further improve the fit of the shoe 1 with the heel position.
In the present embodiment, the upper end portion 9a of the stitched portion 9 of each panel member 4 and the lining member 6 is positioned above the upper end portion 7a of the heel counter 7 at least at the position where the stitched portion 9 is disposed, but may be positioned below the upper end portion 7a of the heel counter 7, or may be positioned at a position corresponding to the upper end portion 7a of the heel counter 7 in the vertical direction.
