AI Technical Summary
Existing shoe designs, particularly those with a belt-like foot wrap, struggle to apply sufficient pressure to the sole of the wearer's foot, especially during dynamic movements, as they fail to flexibly follow the changing sole shape.
The shoe incorporates a casing formed by combining multiple linear bodies that surround the foot from below, with shoelaces connected to inner and outer foot portions, allowing the casing to flexibly adjust to sole shape changes and apply pressure to the sole.
This configuration ensures adequate pressure is applied to the sole, improving the fitting feeling and flexibility during movement, enhancing comfort and fit.

Summary of the Invention
Problems to be Solved by the Invention
[0004] In order to improve the fitting feeling, it is important to apply pressure not only to the instep of the wearer's foot but also to the sole. However, the above-mentioned foot wrap formed of a belt-like member is difficult to flexibly follow changes in the sole shape according to the movement of the wearer's foot in a state where the tension accompanying the tightening of the shoe laces acts. Therefore, in the shoes described in Patent Document 1, it may be difficult to apply sufficient pressure to the sole of the wearer's foot. Particularly in a scene used for sports, since the sole shape of the wearer changes drastically, the influence is likely to appear significantly.
[0005] This disclosure has been made in view of the above circumstances, and provides shoes capable of improving the fitting feeling.
Means for Solving the Problems
[0006] The shoes of this disclosure include a sole, an upper provided on the upper side of the sole, and shoelaces provided on the upper. The upper includes a base that covers at least a portion of the wearer's foot, and a casing disposed inside the base. The casing has an inner foot portion disposed on the inner foot side of a housing space in which the wearer's foot is housed, an outer foot portion disposed on the outer foot side of the housing space, and a lower portion disposed below the housing space, and is configured to surround at least a portion of the wearer's foot from below. The casing is formed by combining a plurality of linear bodies. The shoelaces are connected to the inner foot portion and the outer foot portion, respectively, via lacing holes provided on the base.

[0008] Figure 1 is a perspective view showing a shoe 1 according to one embodiment of the present disclosure. The shoe 1 can be used as a sports shoe such as a running shoe, a walking shoe, or a casual shoe. However, the use of the shoe 1 is not particularly limited. The wearer of the shoe 1 is assumed to be a person with a standard build and feet that fit the size of the shoe 1.
[0009] In this embodiment, a shoe for the left foot 1 is used as an example for explanation, but the explanation can be similarly applied to a shoe for the right foot. The shoe for the right foot is formed to be symmetrical to the shoe for the left foot, or to be generally similar in shape.
[0010] Regarding the terminology used to indicate direction, the foot length direction refers to the direction in which the shoe center SC (see Figure 4), which is the centerline of shoe 1 in a top view (plan view), extends. The foot width direction refers to the direction perpendicular to the foot length direction in a top view. The front refers to the direction from the heel to the toes, and the back refers to the opposite direction. The medial side refers to the first toe side of the foot in the foot width direction, and the lateral side refers to the fifth toe side of the foot in the foot width direction. The lower side refers to the side towards which gravity is directed when shoe 1 is placed on a horizontal surface, and the upper side refers to the opposite side.
[0011] The shoe 1 comprises a sole 2, an upper 3 provided above the sole 2, and shoelaces 4 provided on the upper 3. The wearer's foot is supported from below by the sole 2 and covered from above by the upper 3. The upper 3 is joined to the sole 2 by adhesive or sewing. The upper 3 is provided with an opening 31 for inserting the wearer's foot. The inner surface of the opening 31 is formed by an inner layer 9, which will be described later. In this embodiment, shoelaces 4 are provided in pairs, left and right, and for convenience of explanation, they may be distinguished and referred to as shoelaces 4M and 4L.
[0012] FIG. 2 is a longitudinal sectional view of the shoe 1 in the heel side region that supports the heel of the wearer's foot. FIG. 3 is a longitudinal sectional view of the shoe 1 in the instep region that faces the instep of the wearer's foot, and the illustration of the shoe lace 4 is omitted. FIGS. 2 and 3 schematically show the front view cross sections of the shoe 1 cut along the foot width direction. The upper 3 forms an accommodation space 30 in which the wearer's foot is accommodated together with the sole 2. In the present embodiment, the upper 3 has a midsole 32 that covers the sole of the wearer's foot. The midsole 32 is joined to the sole 2 by adhesion, sewing, or the like. An insole (not shown) may be mounted on the upper side of the midsole 32. When the insole is mounted, the lower portion 6B described later is disposed below the insole.
[0013] The upper 3 includes a base 5 that covers at least a part of the wearer's foot and an enclosure 6 disposed inside the base 5. From the perspective of FIG. 1, the enclosure 6 is hidden by the cloth-like base 5. In FIGS. 2 and 3, the enclosure 6 is represented by a thick line. The base 5 has a toe opening 51 that extends forward from the mouth part 31 and string-through parts 52 provided on the left and right side edges of the toe opening 51. The string-through parts 52 are formed by a plurality of holes arranged at intervals along the foot length direction. In FIG. 1, the shoe lace 4 is inserted through the string-through parts 52, and the specific manner thereof will be described later.
[0014] In the present embodiment, a tongue 7 that covers at least a part of the wearer's toe is disposed below the shoe lace 4. The tongue 7 is configured to cover the range from the front part of the wearer's ankle to the toe while closing the toe opening 51 from below. When the shoe lace 4 is tightened, the tongue 7 is pressed downward and pressure acts on the wearer's toe, thereby improving the fitting feeling. As specifically shown below, the shoe 1 of the present embodiment is provided with a configuration for applying pressure not only to the wearer's toe but also to the sole, whereby the fitting feeling can be further improved.
[0015] FIG. 4 is a development view of the base body 5, and the illustration of the shoe lace 4 is omitted. The base body 5 includes an outer layer 8 that forms the outer surface of the upper 3 and an inner layer 9 that is located inside the outer layer 8. The enclosure 6 is disposed between the outer layer 8 and the inner layer 9. FIG. 5 is a development view of the enclosure 6 and corresponds to the state where the outer layer 8 is removed from FIG. 4. FIG. 6 is a development view of the enclosure 6 with the shoe lace 4 connected, and the position of the string-through portion 52 is indicated by a broken line. FIG. 7 is a side view of the enclosure 6 as viewed from the inner foot side. FIG. 8 is a side view of the enclosure 6 as viewed from the outer foot side. FIG. 9 is a bottom view of the enclosure 6 as viewed from the lower side. In FIGS. 7 to 9, the feet of the wearer are depicted together with the enclosure 6 respectively.
[0016] As shown in FIGS. 2 to 9, the enclosure 6 has an inner foot side portion 6M disposed on the inner foot side of the accommodation space 30, an outer foot side portion 6L disposed on the outer foot side of the accommodation space 30, and a lower side portion 6B disposed on the lower side of the accommodation space 30. The enclosure 6 is configured to surround at least a part of the wearer's foot from below. The enclosure 6 is formed by combining a plurality of linear bodies 60. The shoe lace 4 is connected to each of the inner foot side portion 6M and the outer foot side portion 6L via a string-through portion 52 provided in the base body 5. As shown in FIG. 6, the shoe lace 4L is connected to the outer foot side portion 6L, and the shoe lace 4M is connected to the inner foot side portion 6M.
[0017] According to such a configuration, by tightening the shoe lace 4 to apply tension to the enclosure 6, each of the inner foot side portion 6M and the outer foot side portion 6L is pulled up, and as a result, the lower side portion 6B is pulled up and pressure acts on the sole of the wearer's foot. Moreover, since the enclosure 6 is formed by combining a plurality of linear bodies 60, it is easy to move even when tension acts due to the tightening of the shoe lace 4, and can flexibly follow the change in the sole shape according to the movement of the wearer's foot. For this reason, sufficient pressure can be applied to the sole of the wearer's foot to improve the fitting feeling well.
[0018] As shown in Figure 4, the outer layer 8 includes a reinforcing member 81 that reinforces the side edge of the instep opening 51, a reinforcing member 82 that reinforces the front end of the upper 3, and a reinforcing member 83 that reinforces the rear end of the upper 3. Materials with excellent durability and abrasion resistance are preferably used for each of the reinforcing members 81 to 83. In Figure 4, the reinforcing member 83 is shown separately for the medial and lateral sides, but it may be a single member. The lower edge of the outer layer 8 is joined to the sole 2 or insole 32. The joining point of the lower edge of the outer layer 8 is set in the range from the front end 8a to the rear end 8b of the lower edge.
[0019] As shown in Figures 2 to 6, the inner layer 9 includes the tongue 7. Moreover, the inner layer 9 is used as a lining that forms the inner surface of the upper 3. In other words, the inner layer 9 is formed as a component in which the tongue 7 is integrated with the lining. However, it is not limited to this, and the inner layer 9 may be formed from components separate from the tongue 7 and the lining.
[0020] In this embodiment, the inner foot portion 6M and the outer foot portion 6L are covered by the inner layer 9 so as not to be exposed to the housing space 30. With this configuration, discomfort or unpleasant feeling caused by the touch of the linear body 60 forming the inner foot portion 6M and the outer foot portion 6L can be effectively reduced. The enclosing body 6 is positioned between the outer layer 8 and the inner layer 9, but is not limited to this, and may be positioned inside the inner layer 9. Furthermore, the base body 5 is not limited to a two-layer structure that incorporates a gap in which the enclosing body 6 is positioned, but may, for example, be a single-layer structure with the enclosing body 6 positioned inside. Even in such a configuration, the enclosing body 6 will be positioned inside the base body 5.
[0021] A gap 91 is formed between the sole 2 and the lower edge of the inner layer 9, through which the linear body 60 (specifically, the linear bodies 61 and 66 described later), which will form the lower portion 6B, can pass. In Figures 5 and 6, the area where the gap 91 is formed is indicated by a dashed-dotted line frame. The lower edge of the inner layer 9 is joined to the sole 2 or insole 32, except in the area where the gap 91 is formed. That is, the joining point of the lower edge of the inner layer 9 is set in the area from the front end 9a to the rear end 9b of the lower edge, excluding the gap 91. In the gap 91, the lower edge of the inner layer 9 is not joined to the sole 2 and insole 32, so the linear body 60 can pass through the gap between the outer layer 8 and the inner layer 9.
[0022] In this embodiment, the inner foot portion 6M and the outer foot portion 6L are arranged so as not to be exposed to the outside of the base 5. The shoelace 4 is connected to the inner foot portion 6M and the outer foot portion 6L inside the base 5. As shown in Figures 1 and 6, the shoelace 4M is located outside the base 5 and the inner foot portion 6M is located inside the base 5, but the shoelace 4M is connected to the inner foot portion 6M via the eyelet 52, specifically by a part of the shoelace 4M entering the inside of the base 5 through the eyelet 52. The connection between the shoelace 4L and the outer foot portion 6L is similar. Thus, the connection point between the shoelace 4 and the encasing 6 is located inside the base 5, specifically in the gap between the outer layer 8 and the inner layer 9.
[0023] The enclosing body 6 is formed by a plurality of linear bodies 60 that are independent of each other. In this embodiment, the enclosing body 6 is formed by six linear bodies 60 as shown in Figures 5 to 9, and for the sake of convenience of explanation, they are distinguished and referred to as linear bodies 61 to 66. The inner foot portion 6M is formed by three linear bodies 61 to 63. The outer foot portion 6L is formed by three linear bodies 64 to 66. The lower portion 6B is formed by two linear bodies 61 and 66. Thus, the inner foot portion 6M and the outer foot portion 6L are each formed by a plurality (specifically three) of linear bodies 60, but this is not limited to this. For example, it is also possible to form the inner foot portion 6M and the outer foot portion 6L each by a single linear body.
[0024] Each of the multiple linear bodies 60 has a fixed portion 60f fixed to the base 5 and an unfixed portion 60n not fixed to the base 5. The fixed portion 60f may be, for example, a part in which the linear body 60 is woven or knitted into the base 5. In the drawings, the fixed portion 60f is represented by a black circle. The fixed portion 60f is provided at at least one end of the linear body 60, and in this embodiment, it is provided at both ends. In the inner foot portion 6M, the linear body 61 has five fixed portions 60f indicated by points A, L, M, N and O. The linear body 62 has two fixed portions 60f indicated by points B and P. The linear body 63 has five fixed portions 60f indicated by points C, Q, R, S and T. The outer foot portion 6L is configured symmetrically with the inner foot portion 6M. Each of the multiple linear bodies 60 extends from the anterior edge to the posterior edge of the inner layer 9. The linear bodies 60 are fixed to the inner layer 9, but they may also be fixed to the outer layer 8.
[0025] The non-fixed portion 60n is provided on the part of the linear body 60 other than the fixed portion 60f. The non-fixed portion 60n of one linear body 60 and the non-fixed portion 60n of an adjacent linear body 60 are interlocked. Figure 5 shows an enlarged view of the interlocking portion 60H where the non-fixed portion 60n of one linear body 62 and the non-fixed portion 60n of an adjacent linear body 63 are interlocked, and the linear bodies 60 are interlocked in a similar manner in other places. In this embodiment, each linear body 60 is arranged such that the portion enclosed by two adjacent linear bodies 60 forms a rhombus. As shown in Figure 6, in each of the linear bodies 63 and 64, which are located near the center in the width direction of the foot, a part of the non-fixed portion 60n is interlocked with the shoelace 4.
[0026] Each of the multiple linear bodies 60 extends in a first direction and is arranged in a second direction intersecting the first direction. At least one of the multiple linear bodies 60 (specifically linear bodies 62, 65) has an unfixed portion 60n that is attached to another linear body 60 adjacent to one side in the second direction, and an unfixed portion 60n that is attached to another linear body 60 adjacent to the other side in the second direction, which are alternately set along the first direction. In this embodiment, the first direction is the direction along the leg length direction, and the second direction is the direction along the leg width direction. Each of the multiple linear bodies 60 extends in a zigzag pattern along the leg length direction, alternately protruding to one side and the other side in the leg width direction, and a fixed portion 60f or a hooking portion 60H is set at the protruding portion.
[0027] In this embodiment, the shoelace 4 has a fixed portion 4f fixed to the base 5 and an unfixed portion 4n not fixed to the base 5. In Figure 6, the fixed portion 4f is represented by a black circle indicated by points D and E. The fixed portion 4f is provided at the front end of the shoelace 4. The unfixed portion 4n is provided on the part of the shoelace 4 other than the fixed portion 4f. The shoelace 4 is fixed to the inner layer 9, but it may also be fixed to the outer layer 8. The unfixed portion 4n of the shoelace 4 interlocks with the unfixed portion 4n of an adjacent shoelace 4, or with the unfixed portion 60n of an adjacent linear body 60. Since the arrangement of the shoelace 4 is the same as the arrangement of adjacent linear bodies 60, a redundant explanation is omitted.
[0028] Figure 6 shows a magnified view of the engagement portion 60H where the unfixed portion 4n of the shoelace 4M and the unfixed portion 60n of the adjacent linear body 63 engage with each other. As described above, the engagement portion 60H, which is the connection point between the shoelace 4M and the inner foot portion 6M, is located inside the base body 5, specifically in the gap between the outer layer 8 and the inner layer 9. The connection point between the shoelace 4L and the outer foot portion 6L is similar. In this embodiment, the shoelace 4, located outside the base body 5, and the enclosing body 6, located inside the base body 5, are connected via the lace-threading portion 52, as has already been explained.
[0029] The lowermost of the multiple linear bodies 60, linear bodies 61 and 66, each include portions that pass through the gap 91 and emerge from the gap between the outer layer 8 and the inner layer 9, and these portions form the lower portion 6B. Therefore, the lower portion 6B is formed from a part of linear body 61 and a part of linear body 66. In this embodiment, the lower portion 6B has an engaging portion 60H where the linear bodies 60 engage, as shown in Figure 9. With this configuration, the engaging portion 60H acts as a joint, making it easier for both linear bodies 60 (i.e., linear bodies 61 and 66) to move, so the enveloping body 6 follows the changes in the shape of the sole of the foot in response to the wearer's foot movements more flexibly, thereby improving the fit.
[0030] In this embodiment, the lower portion 6B has multiple (specifically three) engaging portions 60H, but is not limited to this, and for example, a structure with one engaging portion 60H is also possible. However, with such a configuration having multiple engaging portions 60H, multiple pairs of linear bodies 60 extending from the left and right and engaging with each other are provided, so that pressure can be applied to the sole of the wearer's foot over a relatively wide area. The multiple engaging portions 60H shown in Figure 9 are arranged along the length of the foot while being aligned in the width direction of the foot, but is not limited to this.
[0031] Figure 10 is a perspective view showing the lower portion 6B and insole 32 of the enveloping body 6. The insole 32 extends along the length of the foot from the toe-side region TF, which supports the toes of the wearer's foot, through the arch-side region AF, which faces the arch of the wearer's foot, to the heel-side region HF, which supports the heel of the wearer's foot. The lower portion 6B is positioned over at least a part of the arch-side region AF. The enveloping body 6 is configured to surround at least a part of the arch of the wearer's foot from below. This allows pressure to be applied to the arch of the foot, thereby more effectively improving the fit.
[0032] Figure 11 shows a modified example regarding the placement of the lower portion 6B. In this modified example, a cylindrical sleeve 10 having openings 10a is formed at both ends of the insole 32 in the foot width direction, and the lower portion 6B is inserted into the sleeve 10. With this configuration, since the sleeve 10 is interposed between the wearer's sole and the lower portion 6B, discomfort or unease caused by the feel of the linear body 60 forming the lower portion 6B can be effectively reduced. The lower edge of the inner layer 9, which forms a gap 91 (see Figures 5 and 6), may be connected to the edge of the opening 10a.
[0033] In Figure 11, since the sleeve 10 is formed on the insole 32, the relative position of the lower portion 6B with respect to the insole 32 is stable. The central part of the insole 32 in the foot length direction is separated vertically from one end to the other in the foot width direction, and the sleeve 10 is formed by this separated portion. The sleeve 10 is depicted as bulging upwards, but it may be a flat shape that follows the upper surface of the insole 32. From the viewpoint of applying sufficient pressure to a predetermined area on the sole of the wearer's foot, the area ratio of the sleeve 10 to the insole 32 in a top view may be 20% or less. Alternatively, from the viewpoint of expanding the range of motion of the lower portion 6B to accommodate individual differences in the wearer's physical characteristics, the above area ratio may be 20% or more.
[0034] The sleeve 10 shown in Figure 11(A) has a shape in which the sleeve width along the leg length direction is substantially constant. Since a sleeve 10 of this shape can be manufactured relatively easily, manufacturing costs can be reduced. The sleeve 10 shown in Figure 11(B) has a shape in which the sleeve width along the leg length direction increases toward the center in the leg width direction. With this configuration, the movement of the lower portion 6B along the leg length direction is suppressed at both ends in the leg width direction, while the movement of the lower portion 6B along the leg length direction is permitted at the center in the leg width direction. In the illustrated example, the sleeve 10 is formed in the shape of an inverted hourglass, but it is not limited to this, and may be oval, for example.
[0035] The linear body 60 forming the enveloping body 6 can be made of, for example, a yarn made by bundling multiple fibers, a linear form of resin, or a twisted yarn. The material for the linear body 60 can be, for example, polyurethane-based thermoplastic elastomer, polyurethane, nylon, spandex, Kevlar®, ultra-high molecular weight polyethylene, or SCY (Single Covered Yarn) or DCY (Double Covered Yarn) covered with polyurethane. It is preferable that the linear body 60 be formed from a resin material that is easily recyclable at the same time as the upper 3. The linear body 60 of the medial foot portion 6M is formed from the same material as the linear body 60 of the lateral foot portion 6L, but is not limited to this. The shoelace 4 may be made from the same material as the linear body 60 forming the enveloping body 6, or from a different material.
[0036] The connection between the shoelace 4 and the surrounding body 6 is not limited to the embodiment shown above, and various modifications are possible. For example, the inner foot portion 6M and the outer foot portion 6L each have a portion exposed to the outside of the base 5, and the shoelace 4 is connected to the inner foot portion 6M and the outer foot portion 6L respectively on the outside of the base 5. In this case, the shoelace 4 may be passed through the lacing portion 52, or the linear body 60 forming the inner foot portion 6M and the outer foot portion 6L may be passed through it. Other embodiments of the connection between the shoelace 4 and the surrounding body 6 will be described with reference to Figures 12 to 14.
[0037] Figure 12 is a perspective view of shoe 1. Figure 13 is an unfolded view of the enclosure 6 of shoe 1, but the outer foot portion 6L is omitted to make the arrangement of the linear body 60 easier to understand. Figure 14 is an unfolded view of the enclosure 6, showing both the inner foot portion 6M and the outer foot portion 6L. In Figures 12 to 14, the shoelaces are not shown. This embodiment can be configured in the same way as the previously described embodiment with reference to Figures 1 to 11, except for the configuration described below, so the commonalities will be omitted and the differences will be mainly described. Components that have already been described are given the same reference numerals and redundant explanations will be omitted.
[0038] In this embodiment, each of the medial foot portion 6M and the lateral foot portion 6L includes a loop 60L formed by a linear body 60 exposed to the outside of the base 5. The shoelace is inserted through the loop 60L. The loop 60L is spaced apart along the length of the foot at the left and right side edges of the instep opening 51. Since the tension of the loop 60L can be individually changed by inserting the shoelace into the loop 60L, the fit of the shoe 1 can be adjusted more flexibly compared to a normal lace-up shoe. The shoelace is located outside the base 5, and each of the medial foot portion 6M and the lateral foot portion 6L is located inside the base 5, but the shoelace is connected to each of the medial foot portion 6M and the lateral foot portion 6L via a lacing section 52, specifically by exposing a part of the linear body 60 to the outside of the base 5 via the lacing section 52.
[0039] In this embodiment, the surrounding body 6 is formed by eight linear bodies 60 as shown in Figure 14, and for the sake of convenience of explanation, they will be distinguished and referred to as linear bodies 61 to 68. The inner foot portion 6M is formed by four linear bodies 61 to 63 and 67. The outer foot portion 6L is formed by four linear bodies 64 to 66 and 68. The lower portion 6B is formed by two linear bodies 61 and 66. The linear bodies 61 to 66 are configured in the same manner as in the previously described embodiment. The outer foot portion 6L is configured symmetrically with the inner foot portion 6M.
[0040] The linear body 67 has two fixing parts 60f indicated by points D and U. The linear body 67 extends in a zigzag pattern along the length of the foot, alternately protruding to one side and the other side in the width direction of the foot. The portion of the linear body 67 that protrudes to the inner side of the foot is attached to the adjacent linear body 63. The portion of the linear body 67 that protrudes to the outer side of the foot is exposed to the outside of the base body 5 via the lace-up part 52 on the outer side, rather than the lace-up part 52 on the inner side. The linear body 67 exposed to the outside of the base body 5 is arched between adjacent holes, as shown in Figure 12, thereby forming a loop 60L. The linear body 68 is arranged symmetrically with the linear body 67. The linear bodies 67 and 68 intersect each other and are exposed at the instep opening 51.
[0041] Even with this configuration, tightening the shoelaces 4 and applying tension to the encasing 6 allows sufficient pressure to be applied to the wearer's sole, thereby improving the fit. Moreover, since the linear body 67 forming the inner foot portion 6M is inserted through the outer foot lacing portion 52, and the linear body 68 forming the outer foot portion 6L is inserted through the inner foot lacing portion 52, tightening the shoelaces 4 causes the inner foot portion 6M and the outer foot portion 6L to be strongly pulled towards each other. As a result, sufficient pressure is applied to the wearer's sole by the lower portion 6B, and the upper 3 is firmly tightened, further improving the fit.
[0042] Those skilled in the art will understand that the embodiments described above are specific examples of the following embodiments.
[0043] [1] The shoes of this disclosure include a sole, an upper provided on the upper side of the sole, and shoelaces provided on the upper. The upper includes a base that covers at least a portion of the wearer's foot, and a surrounding body disposed inside the base. The surrounding body has an inner foot portion located on the inner foot side of a housing space in which the wearer's foot is housed, an outer foot portion located on the outer foot side of the housing space, and a lower portion located below the housing space, and is configured to surround at least a portion of the wearer's foot from below. The surrounding body is formed by combining a plurality of linear bodies. The shoelaces are connected to the inner foot portion and the outer foot portion, respectively, via lace-throughs provided on the base. This configuration can improve the fit.

[0054]
[12] In the shoes described in
[11] above, the lower portion does not have to be positioned in the toe area located in front of the arch area. This configuration is convenient for concentrating the pressure acting on the wearer's sole to the arch, where a stronger fit is desired.
[0055]
[13] In the shoes described in
[11] or
[12] above, the lower portion does not have to be located in the heel region behind the arch region. This configuration is convenient for concentrating the pressure acting on the wearer's sole to the arch, where a stronger fit is desired.
[0056]
[14] In any one of the shoes described in [1] to
[13] above, the lower portion may have an interlocking portion into which the linear body engages. With this configuration, the interlocking portion acts as a joint, making it easier for the linear body to move. As a result, the enveloping body follows the changes in the shape of the sole of the foot in response to the wearer's foot movements more flexibly, thereby improving the fit.
[0057]
[15] In any one of the shoes described in [1] to
[14] above, a tubular sleeve having openings at both ends in the width direction of the foot may be provided, and the lower portion may be inserted into the sleeve. With such a configuration, since the sleeve is interposed between the wearer's sole and the lower portion, discomfort or unease caused by the feel of the linear body forming the lower portion can be effectively reduced.
[0058]
[16] In the shoes described in
[15] above, the sleeve may be formed in the insole. This stabilizes the relative position of the lower portion with respect to the insole.
[0059]
[17] In the shoes described in
[15] or
[16] above, the sleeve may have a shape in which the sleeve width along the length of the foot increases toward the center in the width of the foot. With such a configuration, movement of the lower portion along the length of the foot is suppressed at both ends in the width of the foot, while movement of the lower portion along the length of the foot is permitted in the center of the width of the foot.
