Disclosure of Invention

Problems to be solved by the invention

The present inventors have obtained the following recognition regarding the fastening mechanism and the fit of the upper.

In order to shorten the time required to put on or take off the shoe, it is desirable to easily fasten the upper. However, in the shoe described in patent document 1, since the buckle is fixed to the upper portion of the upper near the wearing opening, the fastening force concentrates near the wearing opening, and the fastening force decreases from the wearing opening toward the toe, so that the gap between the upper and the instep becomes larger, and the fit becomes poor.

In order to improve the fit on the toe side, it is conceivable to strongly fasten the shoelace as a whole, but at this time, the fastening force near the wearing opening becomes too large, which is disadvantageous from the viewpoint of wearing comfort. From these circumstances, the present inventors have recognized that the shoe described in patent document 1 has room for improvement in terms of both easy fastening of the upper and maintaining of fit.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a shoe that can easily fasten a shoe upper and maintain fit.

Means for solving the problems

In order to solve the above problem, a shoe according to an aspect of the present invention includes: a sole; a vamp which is arranged above the sole and accommodates the foot; a fastening portion for giving a fastening force to the upper; and a force transmitting portion for transmitting a fastening force of the fastening portion to a lower portion of the midfoot portion of the upper.

Any combination of the above or a form in which the constituent elements or expressions of the present invention are mutually replaced between a method, an apparatus, a program, a temporary or non-temporary storage medium, a system, or the like in which a program is recorded is also effective as an aspect of the present invention.

(sole)

The sole 10 is a portion for contacting the ground. The sole 10 includes an outsole 12 and an insole 14. An upper 20 is fixed to the upper of the sole 10 by bonding or the like. The sole 10 may also include a midsole between the outsole 12 and the insole 14. Sole 10 may also be of a single sole (uninsole) construction and may also be devoid of insole 14.

(shoe uppers)

The upper 20 is provided above the sole 10 and accommodates the foot. Upper 20 includes: an inner space 20a for receiving the foot. The upper 20 has a central opening 20c formed forward from the wearing opening 20 b. The central opening 20c is not necessarily required, and the upper 20 may have a so-called sock (sock) structure. The upper 20 has: an inner foot portion 22, an outer foot portion 24, a lacing formation 26, and a lacing portion 28. The upper 20 is provided with a tightening portion 30 for applying a tightening force to the upper 20, and a force transmission portion 18 for transmitting the tightening force of the tightening portion 30 to a lower portion of the midfoot portion 20m of the upper 20. In the present embodiment, the force transmission unit 18 includes: a clip 36 for detachably fixing the fastening portion 30 to the upper 20, and a receiving portion 38. The upper 20 is provided with a position adjustment mechanism 42 and a tongue 70. Fig. 1 shows a state in which the clip 36 is not fixed to the upper 20, and fig. 2 and 3 show a state in which the clip 36 is fixed to the upper 20.

(fastening part)

Fastening portion 30 fastens upper 20. The tightening portion 30 of this example is disposed so as to extend across the central opening 20c in the width direction. The tightening portion 30 applies a tightening force to the upper 20 so as to close the central opening portion 20c in the width direction. The fastening portion 30 may include a band-shaped member, a string-shaped member, a band-shaped member, and a string-shaped member. The tightening unit 30 of the present embodiment is a shoelace 30s, and includes: a first portion 32 and a second portion 34 that are contiguous with each other. The first portion 32 is the portion of the lace 30s from the boundary 30b with the second portion 34 to the end 32 e. The second portion 34 is the portion of the lace 30s from the boundary 30b with the first portion 32 to the end 34 e. The boundary 30b and the

end portions

32e and 34e will be described later.

The lace 28 is passed through by the first portion 32 or the second portion 34, and transmits the fastening force of the fastening portion 30 to the upper 20. The string-threading part 28 in this example is a grommet (euslet) having a hole penetrating vertically. The lacing portion 28 is formed in the lacing formation portion 26, and the lacing formation portion 26 is provided at the periphery of the central opening portion 20c of the upper 20. The string-passing formation portion 26 includes: a first formation 26a provided in the inner leg portion 22, and a second formation 26b provided in the outer leg portion 24. The string-passing formation portion 26 may be formed of a low-elasticity material having elasticity lower than that of the surroundings, a material thicker than the surroundings, a material having a higher density than the surroundings, or a material harder than the surroundings, or may be formed of the same material as the surroundings, in order to increase rigidity.

The string threading part 28 of the present embodiment includes: an outer side string passing portion 28e provided on the outer leg side, and an inner side string passing portion 28j provided on the inner leg side. The inner tether 28j is provided in plurality in the first formation portion 26a, and the outer tether 28e is provided in plurality in the second formation portion 26 b. From the viewpoint of flattening the distribution of the fastening force in the front-rear direction, the number (e.g., 5) of the inner string-passing portions 28j is larger than the number (e.g., 4) of the outer string-passing portions 28 e. The number of the inner string passing portions 28j is an odd number, the number of the outer string passing portions 28e is an even number, and the sum of these numbers is an odd number. That is, the outer string-passing portion 28e and the inner string-passing portion 28j are arranged asymmetrically with respect to each other in the width direction.

(fastener)

The clip 36 is a member for detachably fixing the tightening part 30 to a lower portion of the midfoot portion 20m of the upper 20, and corresponds to a force transmission part. The clip 36 is fixed to the upper 20 by being coupled to a receiving portion 38 provided in the upper 20. That is, the clip 36 has: a fixed state of being connected to the receiving portion 38, and an unfixed state of being separated from the receiving portion 38. Preferably, the clip 36 is fixed to the vicinity of the boundary portion 20h between the upper 20 and the sole 10 on the lateral side of the midfoot portion 20m when the clip is fixed, but the receiving portion 38 may be fixed to a line constituting the outline of the upper 20 in plan view or below the line. The receiving portion 38 may be fixed to a side surface of the shoe sole 10. In addition, the contour of upper 20 is a strand that joins the most outwardly protruding portions of upper 20. The clip 36 may be a hook or a hook, a magnet, or the like, as long as the fastening portion 30 can be fixed. The buckle 36 in this example is an external buckle portion of a resin buckle (buckle), and the receiving portion 38 is an internal buckle portion of the buckle. The buckle 36 and the receptacle 38 may also be a front release buckle or a side release buckle.

(position adjusting mechanism)

The shape of the foot varies for each wearer, and it is desirable that the fixing position of the buckle 36 is adjustable. Therefore, the present embodiment has the position adjusting mechanism 42, and the position adjusting mechanism 42 can move the catch 36 in the front-rear direction at the fixed position of the upper 20. For example, the position adjustment mechanism 42 is a slider mechanism. The position adjustment mechanism 42 of the present embodiment includes: a rail member 42b provided on the forefoot portion 24 of the upper 20 and extending in the front-rear direction, and a slider 42s provided slidably in the front-rear direction on the rail member 42 b. The receiving portion 38 is fixed to the slider 42 s. The position adjusting mechanism is not essential, and the position of the receiving portion 38 may be fixed.

Tongue 70 covers central opening 20c on the side of interior space 20a of upper 20. For the tongue 70, a so-called bifurcated tongue (split tongue) may also be used, namely: the widthwise end portions are fixed to the left and right ends of the central opening portion 20c, and the central portion of the tongue 70 is divided left and right.

Reference is also made to fig. 4. Fig. 4 is a plan view showing the periphery of the fastening portion 30. The figure shows a portion of the clip 36 cut away. The plurality of inner tether portions 28j are referred to as insertion portions 28j1, 28j2, 28j3, 28j4, and 28j5 in this order from front to back. The outer string passing portions 28e are referred to as insertion portions 28e1, 28e2, 28e3, and 28e4 in this order from front to back. The insertion portions 28j1, 28j2, 28j3, 28j4, and 28j5 may be arranged at equal intervals or may be arranged at partially unequal intervals. The insertion portions 28e1, 28e2, 28e3, and 28e4 may be arranged at equal intervals or may be arranged at partially unequal intervals.

The insertion portion 28j3 disposed at the center in the front-rear direction of the inner tether portion 28j is particularly referred to as a center insertion portion 28j 3. The portion of the fastening portion 30 that passes through the central penetration portion 28j3 is defined as the boundary 30b of the first portion 32 and the second portion 34. A portion of the fastening portion 30 connected to the rear side from the central insertion portion 28j3 is defined as a first portion 32. The second portion 34 is a portion of the fastening portion 30 that is continuous from the center insertion portion 28j3 to the front side. That is, the first portion 32 and the second portion 34 have a relationship in which one is longer and the other is shorter, and the position of the boundary 30b in the entire length of the tightening portion 30 changes accordingly.

End 32e of first portion 32 and end 34e of second portion 34 are secured to the lateral side of upper 20. In this example, the end 32e of the first portion 32 is fixed to the second insertion portion 28e2 from the front to the rear of the outer tether portion 28 e. Further, the end 34e of the second portion 34 is fixed to a fourth (first from rear to front) insertion portion 28e4 from front to rear of the outer tether portion 28 e. Here, the term "end portion is fixed" means: even if the clip 36 is pulled, the end portion is not dropped from the insertion portion and is held. The fixing structure of the

end portions

32e, 34e is not limited, but in this example, a knot (knot) having a size that cannot pass through the insertion portion 28e is formed at the

end portions

32e, 34 e. The

end portions

32e, 34e may also be constructed using a cord lock member.

As shown in fig. 1, the portions of the shoelace 30s extending from the knots of the

end portions

32e, 34e to the opposite side of the insertion portion 28e are referred to as protruding

cord portions

32j, 34 j. The tip of the projecting

cord portions

32j, 34j may also be free ends. The distal ends of the

extension cord portions

32j, 34j may be cut to an appropriate length according to the wearer.

The shape of the foot will vary for each wearer and, thus, the appropriate length of first portion 32 and second portion 34 will vary. Thus, the length of the first and

second portions

32, 34 is desirably variable. Therefore, in the present embodiment, the lengths of the first portion 32 and the second portion 34 are adjustable at the end 32e of the first portion 32 and the end 34e of the second portion 34.

When the knot position of the end portion 32e is changed to extend the protruding cord portion 32j, the first portion 32 becomes short, and when the protruding cord portion 32j is shortened, the first portion 32 becomes long. When the knot position of the end portion 34e is changed to extend the protruding cord portion 34j, the second portion 34 becomes short, and when the protruding cord portion 34j is shortened, the second portion 34 becomes long. As described above, the knot may be cut to an appropriate length on the tip side. Instead of forming the knot, a length adjustment mechanism of a dial (dial) type, for example, may be provided. In these cases, the length can be easily adjusted.

The path of the first portion 32 from the end 32e will be explained. As shown in fig. 4, first portion 32 extends from insertion portion 28e4 to insertion portion 28j5, from insertion portion 28j5 to insertion portion 28j1, from insertion portion 28j1 to insertion portion 28e1, and then from insertion portion 28e1 to central insertion portion 28j 3. In the first portion 32, a portion extending from the insertion portion 28j5 to the insertion portion 28j1 is drawn inward to form a guide portion 32 p. The guide portion 32p is provided with a catch 36. The portions of the first portion 32 extending between the inner tether portion 28j and the outer tether portion 28e are referred to as inner and outer extension portions 32 k.

The path of the second portion 34 from the end 34e will be explained. As shown in fig. 4, second portion 34 extends from insertion portion 28e2 to insertion portion 28j2, from insertion portion 28j2 to insertion portion 28j4, from insertion portion 28j4 to insertion portion 28e3, and then from insertion portion 28e3 to central insertion portion 28j 3. In the second portion 34, a portion from the insertion portion 28j2 to the insertion portion 28j4 is drawn inward to form a guide portion 34 p. The guide portion 34p is provided with a catch 36. Further, the portions of the second portion 34 extending between the inner tether portion 28j and the outer tether portion 28e are referred to as inner and outer extension portions 34 k.

The

guide portions

32p, 34p of this example pass through passages in the clip 36. Accordingly, by pulling the clip 36, tension is applied to the first portion 32 and the second portion 34, and a fastening force is applied to the upper 20.

The catch 36 is disposed on each of the first portion 32 and the second portion 34. The catch 36 is mounted in a relatively movable manner with respect to the first and

second portions

32, 34. Therefore, by changing the positional relationship between the boundary 30b of the first portion 32 and the second portion 34 and the catch 36, one of the first portion 32 and the second portion 34 can be shortened to enhance the fastening force thereof, and the other can be lengthened to weaken the fastening force thereof.

The first portion 32 and the second portion 34 are respectively divided into:

front portions

32f, 34f disposed further forward than the clip 36, and

rear portions

32b, 34b disposed rearward. That is, the catch 36 is disposed between the

front portions

32f, 34f and the

rear portions

32b, 34 b. By changing the positional relationship of the buckle 36 with respect to the shoelace 30s, the fastening force of one of the

front portions

32f, 34f and the

rear portions

32b, 34b can be weakened, and the fastening force of the other can be strengthened. This makes it possible to adjust the distribution of the tightening force in the front-rear direction.

Reference is also made to fig. 5. Fig. 5 is a plan view showing the positional relationship between the shoelace 30s and the large and small ball portions of the wearer. In this figure, a straight line connecting the small and large ball portions of the wearer is denoted by symbol Lb. The straight line Lb is inclined clockwise by 15 ° with respect to the width direction when viewed in plan.

In the present embodiment, the rearmost portion of the first portion 32 constitutes a top line (top line)30h of the fastening portion 30, and the foremost portion of the first portion 32 constitutes a bottom line (bottom line)30j of the fastening portion 30. In the example of fig. 4, the top line 30h and the bottom line 30j are located more rearward on the outer leg side than on the inner leg side. The top line 30h and the bottom line 30j are inclined by a predetermined angle θ n with respect to the width direction in plan view. The predetermined angle θ n may be an angle (for example, 15 °) approximating a positional relationship between the large and small ball portions of the wearer when viewed on a plane.

The positional relationship of the insertion portion 28j5 through which the top line 30h passes and the insertion portion 28e4 as viewed in plan is similar to the positional relationship of the large ball portion and the small ball portion of the wearer. That is, a straight line connecting insertion portion 28j5 and insertion portion 28e4 extends substantially parallel to a straight line connecting the large ball portion and the small ball portion. The positional relationship between the insertion portion 28j1 through which the bottom thread 30j passes and the insertion portion 28e1 as viewed in plan is similar to the positional relationship between the large and small ball portions of the wearer. That is, a straight line connecting insertion portion 28j1 and insertion portion 28e1 extends substantially parallel to a straight line connecting the large ball portion and the small ball portion.

In order to absorb the impact of walking or the like and reduce fatigue, it is desirable to maintain the lateral arch from the large ball portion to the small ball portion. Therefore, the tightening section 30 of the present embodiment is configured such that a tightening force acts in a direction in which the large ball portion and the small ball portion approach each other. In particular, the tightening portion 30 is configured to tighten the upper 20 in a direction substantially parallel to a line connecting the small ball portion and the large ball portion.

More specifically, the average of the extending directions of the inner and outer extending

portions

32k and 34k extending between the inner tether portion 28j and the outer tether portion 28e is set to be substantially parallel to a straight line connecting the small ball portion and the large ball portion. A straight line connecting the large ball portion and the small ball portion is inclined by approximately 15 ° with respect to the width direction so as to be positioned more rearward than the inner foot side on the outer foot side.

In the first portion 32, the inner and outer extending portions 32k extending from the insertion portion 28e1 to the central insertion portion 28j3 are inclined so as to be positioned more rearward on the inner leg side than on the outer leg side. In the second portion 34, the inner and outer extensions 34k extending from the insertion portion 28e3 to the central insertion portion 28j3 are greatly inclined so as to be positioned more rearward on the outer leg side than on the inner leg side. When these average values are included, the average value of the extending directions (i.e., the directions of tension) of the inner and outer extending

portions

32k and 34k is inclined by approximately 15 ° with respect to the width direction.

The top line of the wearing opening 20b will be explained. As shown in fig. 1, the top line of the wearing opening 20b may be provided symmetrically on the outer leg side and the inner leg side, but in the present embodiment, from the viewpoint of easy wearing, it is provided asymmetrically on the outer leg side and the inner leg side. That is, when wearing shoes, the wearer often inserts the shoe into the wearing opening 20b with the foot turned inside out (with the big toe side facing upward), and the wearer can easily wear the shoe with the big toe side of the wearing opening 20b open. Therefore, the top line 20e on the inner foot side (big toe side) of the wearing opening 20b of the upper 20 is positioned forward of the top line 20j on the outer foot side of the wearing opening 20 b. The top thread 20j is located in the vicinity of the insertion portion 28e4 to which the rear end 32e of the shoelace 30s is fixed. As shown in fig. 2, the top line 20j is located further above the top line 20 e.

The features of the shoe 100 of the present embodiment configured as described above will be described. The shoe 100 includes: a sole 10; a shoe upper 20 provided above the shoe sole 10 and accommodating a foot; a fastening portion 30 for giving a fastening force to the upper 20; and a force transmitting portion 18 for transmitting the fastening force of the fastening portion 30 to a lower portion of the midfoot portion 20m of the upper 20. According to this structure, the fastening portion 30 can be fixed to the lower portion of the midfoot portion 20m of the upper 20, and thus, it can contribute to flattening of the distribution of the fastening force in the front-rear direction.

The force transmission unit 18 includes: and a clip 36 for detachably fixing the fastening portion 30 to the upper 20. At this time, the fastening force can be transmitted to the upper 20 with a simple structure.

The clip 36 is fixed to the upper 20 near the boundary 20h with the sole 10. In this case, the foot can be reliably provided with tightening force, and the distribution of the tightening force can be flattened.

The fastening portion 30 includes: the first and

second portions

32 and 34 are continuous with each other, and the catch 36 is provided for each of the first and

second portions

32 and 34. By changing the positional relationship between the boundary 30b of the first portion 32 and the second portion 34 and the catch 36, the fastening force of one of the first portion 32 and the second portion 34 can be strengthened, and the fastening force of the other can be weakened. In this case, the fastening amount can be adjusted near the wearing opening 20b and on the toe side.

Fastening portion 30 is a lace, and upper 20 has: the lacing portion 28 through which the first portion 32 or the second portion 34 passes, an end portion 32e of the first portion 32 and an end portion 34e of the second portion 34 are secured to the lateral side of the upper 20, and the clasp 36 is secured to the lateral side. At this time, the shoelace can be easily tightened from the medial aspect to the lateral aspect. Can contribute to flattening of the distribution of the fastening force.

The threading portion 28 includes: an outer string-passing portion 28e provided on the outer leg side and an inner string-passing portion 28j provided on the inner leg side, wherein the number of the inner string-passing portions 28j is larger than the number of the outer string-passing portions 28 e. In this case, since the inner string portion 28j can be fastened at a plurality of points in a dispersed manner, it can contribute to flattening of the distribution of the fastening force.

The lengths of the first portion 32 and the second portion 34 are adjustable at least one of the catch 36, the end 32e of the first portion 32, and the end 34e of the second portion 34. At this time, the length of the shoelace 30s is adjusted in accordance with the foot size.

The rearmost portion of the first portion 32 constitutes a top line 30h of the fastening portion 30, the foremost portion of the first portion 32 constitutes a bottom line 30j of the fastening portion 30, and the top line 30h and the bottom line 30j are located more rearward on the outer leg side than on the inner leg side. At this time, lines corresponding to heel and Metatarsophalangeal (MP) joints may be appropriately fastened.

A position adjusting mechanism 42 is provided, and the position adjusting mechanism 42 can move the fixing position of the catch 36 in the front-rear direction. At this time, the catch 36 may be fixed in place in the front-rear direction.

The top line 20e on the inner side of the wearing opening 20b of the upper 20 is located forward of the top line 20j on the outer side of the wearing opening 20 b. At this time, when the shoe 100 is worn, the inner leg side of the wearing opening 20b is opened, and thus putting on and taking off is facilitated.

The tightening section 30 tightens the upper 20 in a direction substantially parallel to a straight line connecting the small ball section and the large ball section. At this time, when the foot receives a load, the small ball part and the large ball part spread and a force acts so that the lateral arch collapses, but the small ball part and the large ball part can be brought close to each other to fasten the foot, thereby contributing to maintaining the lateral arch.

[ modified examples ]

Hereinafter, a modified example will be described. In the drawings and the description of the modified examples, the same or equivalent constituent elements and members as those of the embodiment are denoted by the same reference numerals. Descriptions overlapping with the embodiments will be omitted as appropriate, and the structural emphasis different from the embodiments will be described.

[ first modification ]

In the description of the embodiment, the tightening unit 30 is constituted only by the shoelace 30s, but the present invention is not limited thereto. The fastening portion 30 may also comprise a band-shaped member. Fig. 6 is a plan view schematically showing a shoe 200 according to a first modification, and corresponds to fig. 1. Fig. 7 is a side view of the shoe 200, corresponding to fig. 3. The fastening portion 30 of the present modification includes a band-shaped portion 30m in addition to the shoelace 30s, and differs from the embodiment in that the first surface fastener 36m and the second surface fastener 38m are used instead of the buckles for the buckles 36.

As shown in fig. 6, a base end portion 30n of the strip portion 30m is fixed to the inner foot portion 22 of the upper 20. The belt-shaped portion 30m has a short strip shape extending in the width direction from the base end portion 30n, and the first surface fastener 36m is provided at the tip end portion 30 p. In the vicinity of the distal end portion 30p of the belt-like portion 30m, a guide support portion 30q for passing the

guide portions

32p, 34p of the shoelace 30s is formed. The guide support portion 30q is a passage through which the

guide portions

32p, 34p pass forward and backward.

The second surface fastener 38m is provided near a boundary 20h between the upper 20 and the sole 10. One of the first surface fastener tape 36m and the second surface fastener tape 38m has a loop surface, and the other has a burr surface. Therefore, the first surface fastener 36m is detachably fixed to the second surface fastener 38 m. The upper 20 is fastened by the first surface fastener 36m being fixed to the second surface fastener 38 m. The fastening of the upper 20 is released by separating the first surface fastener 36m from the second surface fastener 38 m.

In the description of the first modification, the fastening section 30 is formed of a single band-shaped member, but the present invention is not limited thereto, and the fastening section 30 may include a plurality of band-shaped members. For example, the fastening portion 30 may have two or more short strip-shaped portions extending in the width direction. In this case, the proximal ends of the two or more short bar-shaped portions may be connected to each other or may be separated from each other. Further, the tip portions of two or more short strip-shaped portions may be connected to each other or may be separated from each other.

[ second modification ]

Referring to fig. 8, a shoe 300 according to a second modification will be described. Fig. 8 is a side view schematically showing a shoe 300 according to a second modification, and corresponds to fig. 3. The force transmission unit 18 of the present modification includes: a clasp 36 for detachably fixing the lace 30s to the upper 20, and a member for pulling the intermediate portion of the lace 30s toward the lower portion of the midfoot portion 20m of the upper 20. In particular, in the present modification, the fixing structure of the

guide portions

32p and 34p of the tightening portion 30 is different from that of the embodiment, and the other structures are the same. Therefore, the fixing structure of the

guide portions

32p and 34p will be mainly described. The fixing structure of the

guide portions

32p and 34p of the present modification includes: an extension 44 and an intermediate support 46. The intermediate support portion 46 is exemplified as a member that pulls the intermediate portion of the shoelace 30s closer, and corresponds to a force transmitting portion.

(elongation)

In the description of the embodiment, the

guide portions

32p, 34p of the shoelace 30s are directly coupled to the buckle 36, but the

guide portions

32p, 34p of the present modification are coupled to the buckle 36 via the extension portion 44. The extension 44 is a belt-shaped member formed of a flexible material such as cloth. A ring portion 44b for passing the

guide portions

32p, 34p is provided on the proximal end side of the extension portion 44. The ring portion 44b may be formed by folding back, for example. The loop portion 44b need not be a loop closed, but may be a partially open loop. Instead of the ring portion 44b, a hook may be provided on the proximal end side of the extension portion 44. The clip 36 is fixed to the distal end side of the extension 44. The buckle 36 is an external buckle portion of a resin buckle.

The fixing position of the receiving portion 38 is not limited, and in the present modification, the receiving portion 38 is fixed to the lateral side of the hindfoot portion 20g of the upper 20. In particular, the receiving portion 38 is fixed to or above the thread forming the top contour of the upper 20. The receiving portion 38 may be fixed to a lower portion than the wire. The receiving portion 38 may be directly fixed to the upper 20, but the receiving portion 38 in this example is fixed to the upper 20 via a strap 38 b. Alternatively, bolster 38 may be secured directly to upper 20. The receiving portion 38 is an inner buckle portion of the resin buckle.

The intermediate support portion 46 gathers and supports the intermediate regions of the

guide portions

32p, 34p in order to concentrate the direction of tension (tightening force) of the

guide portions

32p, 34p of the lace 30s toward the lower portion of the midfoot portion 20m of the upper 20. That is, the intermediate support portion 46 draws the

intermediate portions

32q, 34q of the

guide portions

32p, 34p toward the lower portion of the midfoot portion 20m and supports them.

The intermediate support portion 46 is not limited in its configuration as long as it can apply tension to the

guide portions

32p, 34p toward a predetermined position. In the example of fig. 8, the intermediate support portion 46 is a member having a ring portion 46b for passing the

intermediate portions

32q, 34q of the

guide portions

32p, 34p, and gives tension toward the front lower direction to the

intermediate portions

32q, 34 q. The intermediate support portion 46 is a belt-shaped member formed of a flexible material such as cloth, and the loop portion 46b is formed by folding back the belt-shaped member. The loop portion 46b need not be a loop closed, but may be a partially open loop. Further, the intermediate support portion 46 may have hooks for passing the

intermediate portions

32q, 34q or protrusions for catching the

intermediate portions

32q, 34q instead of the ring portions 46 b. The upper edge of the ring portion 46b is desirably positioned lower than the outline of the upper.

The base end portion 46a of the intermediate support portion 46 is fixed to the vicinity of the boundary portion 20h with the shoe sole 10 of the upper 20. The ring portion 46b is located rearward and upward relative to the base end portion 46 a. When the catch 36 and the receiving portion 38 are disposed rearward, the positional relationship between the base end portion 46a of the intermediate support portion 46 and the ring portion 46b is configured as described above, whereby tension (tightening force) of the

guide portions

30s and 34p can be further applied to the upper. When the clip 36 and the like are provided on the front side, the ring portion 46b is preferably arranged on the front upper side of the base end portion 46 a.

A method of using the fixing structure of the

guide portions

32p and 34p will be described. The extension portion 44 connected to the

guide portions

32p and 34p and the hook 36 connected to the tip end side thereof are connected to the receiving portion 38 in a state where the hook 36 is inserted through the ring portion 46b of the intermediate support portion 46, whereby the fastening portion 30 can fasten the upper 20. In this state, the tension toward the lower portion of the midfoot portion 20m acts on the

guide portions

32p, 34p, and the variation in the distribution of the tightening force of the upper 20 in the front-rear direction can be reduced. Then, by separating the catch 36 from the receiving portion 38, the tightening portion 30 is in the non-tightened state, and the tightening of the upper 20 is released.

The intermediate support portion 46 may be configured to be movable in the front-rear direction by a position adjustment mechanism.

The clip 36 and the receiving portion 38 may be a surface fastener, a hook, a magnet, or the like, instead of the resin buckle.
