Description

  The present invention relates to a belt-type shoe provided with an upper belt for adjusting the tightening state of the upper.

  A shoe that adjusts the tightening state of the former with a shoelace (a so-called lace shoe) must be released when the shoe is put on and taken off. Also, if the shoelaces loosen when worn, the shoelaces must be retightened, which is very troublesome. For this reason, there are many people who refrain from lace shoes, and a shoe in which the tightening state of the upper can be adjusted with the upper belt (hereinafter, this type of shoe is sometimes referred to as a “belt-type shoe”). .) Is popular.

  There are various types of belt-type shoes, but one end (base end) of the upper belt is a fixed end fixed to the upper and the other end (front end) of the upper belt is freely removable from the upper. The mainstream is the one that can adjust the tightening state of the upper by adjusting the position at which the tip of the upper belt is fastened to the upper.

  In this type of belt-type shoe, there are various means for fastening the tip of the upper belt to the upper, but considering the ease of operation and low manufacturing costs, the outer surface of the upper and the upper belt The inner surface of the tip (the surface facing the inner side when the tip of the upper belt is fastened to the upper) is provided with a male surface fastener on one side and a female surface fastener on the other side (surface fastener type) Has become commonplace.

  In addition to the hook-and-loop fastener type, the belt-type shoe has a pin supported by the upper in which the pin is inserted into one of a plurality of holes provided at a predetermined interval at the tip of the upper belt ( Pin buckle type), a belt with a belt in between a pair of plates supported by the upper (plate buckle type), or an upper belt between multiple rings supported by the upper There are things that are sandwiched (ring buckle type) and those that use a snap button or other button to fasten the upper belt to the upper (button type).

  The belt-type shoes can be easily put on and taken off as compared with the string shoes, and thus have been used in shoes for various purposes. However, with belt-type shoes, when the top of the upper belt was fastened to the upper shell, the degree of tightening of the upper was uniform (for example, if the upper belt was fastened tightly, the upper was not removed until the shoes were removed). There were few things that were comfortable to wear. In addition, although belt-type shoes can be easily put on and taken off as compared with string shoes, they cannot be put on or taken off without removing the tip of the upper belt from the upper cover.

  In view of such a situation, until now, there are belt-type shoes (for example, refer to Patent Documents 1 to 3) in which the entire upper belt is formed of an elastic material, and a predetermined section near the root of the upper belt. Shoes (for example, see Patent Documents 4 and 5) formed of an elastic material have been proposed. This makes it possible to expand and contract the upper belt according to the movement of the foot, etc., so that not only the comfort of the shoe is improved, but also the shoe can be worn without removing the tip of the upper belt from the upper It can also be taken off.

  However, the belt-type shoes sometimes have the tip of the upper belt detached from the upper shell when the wearer performs violent movements. In such a case, as shown in FIG. 6, when the stretchable material 11 is used for the upper belt 10, as shown in FIG. 7, when the upper belt 10 is removed from the upper 20, the stretchable material is used. 11 could not support the upper belt 10 on the front end side more than that, and the entire upper belt 10 was easily hung from the upper 20.

  For this reason, a wearer of a belt-type shoe in which the stretchable material 11 is used for the upper belt 10 may step on the upper belt 10 that is detached from the upper cover 20 by himself. Therefore, the belt-type shoes using the stretchable material 11 for the upper belt 10 are not only comfortable and easy to wear, but also small children who are likely to fall even if they are slightly worn, elderly people, and patients who receive rehabilitation. As such, it is not necessarily suitable for wearing.

  Not only is it comfortable to wear, it can be put on and taken off without removing the upper belt, but even if the upper belt is removed from the upper shell during wearing, the upper belt does not hang down. It would be sufficient if there were belt-type shoes, but no belt-type shoes that solved these problems were found so far.

Japanese Utility Model Publication No. 56-009203 Noto 3035815 JP 2000-116409 A Japanese Utility Model Publication No. 56-142603 JP 2008-188312 A

  The present invention has been made to solve the above-described problems, and the upper belt does not hinder the movement of the wearer's foot and is not only comfortable to wear, but also can be worn without removing the upper belt. The present invention provides a belt-type shoe that can be taken off and does not hang down even if the upper belt is detached from the upper shell when worn.

  The above problem is a shoe provided with an instep belt for adjusting the tightening state of the instep, and a predetermined section α in the vicinity of the base of the instep belt is formed of an elastic material. This is solved by providing a shoe formed on the upper and having at least a part of the outer surface of the predetermined section α of the upper belt covered with the belt loop.

  As a result, when the upper belt belt is detached from the upper shell and the upper belt is about to be opened, the upper belt belt is supported not to hang down at the upper edge of the belt loop, The upper belt can be naturally returned to the initial position due to the difference in stress generated on the front and back of the bent portion (bent portion). Therefore, even if the tip of the upper belt is once detached from the upper, it is possible to automatically fix the upper end of the upper belt to the upper. The difference in stress generated on the front and back of the upper belt will be described in detail later.

  By the way, the word “top” may mean, in a narrow sense, a portion covering a portion (top) that does not contact the ground on the toe side of the ankle among the portions covering the foot in the shoe. However, in this specification, the term “top” is used to mean a portion of the shoe covering the foot, excluding the shoe sole. Therefore, even a shoe in which a belt loop is formed in a portion covering a foot in a shoe, a portion covering just under the ankle, or a portion covering the heel side from the ankle is included in the technical scope of the present invention. And

  In addition, the term “top” may mean, in a narrow sense, a portion that covers a foot in a shoe and is formed of a continuous face material. However, in this specification, the term “top” is not limited to the case where the portion of the shoe covering the foot is formed of a continuous face material, and a face material having an opening, or other band or string. Even if it is formed by combining these, a net, etc., it is included in the concept.

  In the above shoes, the belt loop is not particularly limited as long as it is formed so as to cover at least a part of the outer surface of the predetermined section α (section formed of stretchable material) in the upper belt. It is preferable that it is formed so as to cover substantially the entire outer surface of the predetermined section α. This not only makes the portion formed of the stretchable material in the upper belt difficult to get dirty, but also prevents the portion from being deteriorated by sunlight, rainwater, and the like, thereby extending the life of the shoe.

  Here, “substantially the entire outer surface of the predetermined section α of the upper belt” means that the predetermined section α of the upper belt has a natural length (the stretchable material is not stretched or contracted along the longitudinal direction of the upper belt). This means substantially the entire outer surface of the predetermined section α. Further, “substantially the whole is covered with the belt loop” means that a range of 80% or more with respect to the entire area of the corresponding portion is covered with the belt loop, preferably 85%. As mentioned above, it means that the range of 90% or more, more preferably 95% or more is covered with the belt loop.

  In the above shoes, the belt threading is not particularly limited in its formation method, and may be formed by providing a pair of slits in the upper, for example. However, in this case, the upper shell may be easily torn starting from the slit or the like. Therefore, the belt loop is formed by stacking a belt-like material having a length longer than the width of the upper belt so as to be substantially perpendicular to the upper belt, and fixing both ends of the belt-like material to the upper shell. preferable. Thereby, it becomes possible to make it difficult to tear an instep, and it becomes possible to lengthen the lifetime of shoes.

  Further, in the above shoe, the length of the stretchable material (predetermined section α) in the direction along the longitudinal direction of the upper belt varies depending on the use of the shoe and the type of stretchable material, and is not particularly limited. However, if the length of the stretchable material in the direction along the longitudinal direction of the upper belt is too short, it becomes difficult to impart desired stretchability to the upper belt. For this reason, the length of the stretchable material in the direction along the longitudinal direction of the upper belt is usually 3 mm or more. The length of the stretchable material in the direction along the longitudinal direction of the upper belt is preferably 5 mm or more, and more preferably 7 mm or more.

  On the other hand, if the length of the stretchable material in the direction along the longitudinal direction of the upper belt is too long, it may be difficult to secure a place for arranging the belt loop. In addition, the upper belt becomes too easy to stretch, and there is a possibility that the upper tightening force of the upper belt may be reduced. Furthermore, there is a possibility that the appearance of the shoes may be deteriorated. For this reason, the length of the stretchable material in the direction along the longitudinal direction of the upper belt is usually 30 mm or less. The length of the stretchable material in the direction along the longitudinal direction of the upper belt is preferably 25 mm or less, and more preferably 20 mm or less.

  Here, “the length of the stretchable material in the direction along the longitudinal direction of the upper belt” means the stretchable material in the direction along the longitudinal direction of the upper belt when the predetermined section α of the upper belt is a natural length. (The minimum value if the length varies depending on the location).

  Furthermore, the stretch rate of the stretchable material in the direction along the longitudinal direction of the upper belt varies depending on the use of the shoe and the length of the stretchable material, and is not particularly limited. However, if the stretch rate of the stretchable material in the direction along the longitudinal direction of the upper belt is too small, it becomes difficult to impart desired stretchability to the upper belt. For this reason, the elongation percentage of the stretchable material in the direction along the longitudinal direction of the upper belt is usually 130% or more. The elongation percentage of the stretchable material is preferably 150% or more, and more preferably 170% or more.

  On the other hand, if the stretch rate of the stretchable material in the direction along the longitudinal direction of the upper belt is too large, the upper belt is likely to be stretched too much, and the tightening force of the upper by the upper belt may be reduced. In addition, it may be difficult to maintain the strength of the upper belt. For this reason, the elongation percentage of the stretchable material in the direction along the longitudinal direction of the upper belt is usually 400% or less. The elongation percentage of the stretchable material in the direction along the longitudinal direction of the upper belt is preferably 300% or less, and more preferably 250% or less.

  Here, the “elongation rate” of the stretchable material in the direction along the longitudinal direction of the upper belt means the elongation rate at constant load (%) measured in accordance with the constant load method defined in “JIS L 1018”. ).

  By the way, the above-mentioned problem is a shoe provided with an instep belt for adjusting the tightening state of the instep, and a predetermined section α in the vicinity of the base of the instep belt formed of an elastic material, and the belt for passing the instep belt The present invention can also be solved by providing a shoe characterized in that a through is formed on the upper and at least a part of the outer surface of the upper belt on the front side of the predetermined section α is covered with the belt through.

  This also not only supports the upper belt at the upper edge of the belt loop so that the upper belt does not hang down when the upper belt belt is detached from the upper shell and the upper belt is about to open. The upper belt can be naturally returned to the initial position by the difference in stress generated on the front and back of the portion (bent portion) bent at the upper edge of the thread. Therefore, even if the tip of the upper belt is once detached from the upper, it is possible to automatically fix the upper end of the upper belt to the upper.

  As described above, according to the present invention, the upper belt does not hinder the movement of the wearer's foot and is not only comfortable to wear, but also can be put on and taken off without removing the upper belt. However, even if the upper belt is detached from the upper shell at the time of wearing, it is possible to provide a belt-type shoe in which the upper belt does not hang down.

1.0 Shoes of First Embodiment A preferred embodiment of the shoes of the present invention will be described more specifically with reference to the drawings. FIG. 1 is a perspective view showing a preferred embodiment (first embodiment) of the shoe of the present invention. FIG. 2 is an enlarged cross-sectional view showing a state in which the periphery of the belt of the shoe of the first embodiment of the present invention is cut by a plane perpendicular to the upper and including the center line along the longitudinal direction of the belt (FIG. 1). AA sectional view in FIG. FIG. 3 shows a state in which the periphery of the belt passing when the upper belt is closed in the shoe of the first embodiment of the present invention is cut by a plane including a center line perpendicular to the upper and along the short direction of the belt passing. It is the expanded sectional view shown (BB sectional drawing in FIG. 1). FIG. 4 shows a state in which the periphery of the belt threading when the upper belt of the shoe of the first embodiment of the present invention is opened is cut by a plane including a center line perpendicular to the upper shell and along the short direction of the belt threading. It is the expanded sectional view shown (sectional drawing corresponded in BB sectional drawing in FIG. 1). 1 to 4, only the shoes for the right foot are illustrated, but the left foot shoe can adopt a configuration that is symmetrical to the shoe for the right foot.

  As shown in FIG. 1, the shoe of the first embodiment of the present invention includes an upper belt 10 for adjusting the tightening state of the upper, and a predetermined section α near the root (base end) of the upper belt 10 is expanded and contracted. It is formed of the material 11. A belt thread 30 for passing the upper belt 10 is formed on the outer surface of the upper 20, and substantially the entire outer surface of the predetermined section α formed of the stretchable material 11 in the upper belt 10 is formed by the belt thread 30. It is in a covered state.

1.1 Upper belt (predetermined section α)
The type of the stretchable material 11 forming the predetermined section α of the upper belt 10 is not particularly limited as long as it is a stretchable material. Examples of the stretchable material 11 include not only those made of synthetic rubber alone or natural rubber alone, but also rubber-woven fabrics made by weaving fibers made of these rubbers with other fibers. In the shoe of the first embodiment, the stretchable material 11 uses a stretchable fiber made of rubber as a warp along the longitudinal direction of the instep belt 10 and a non-stretchable fiber as a weft along the short direction of the instep belt 10. It is formed by a rubber woven fabric using.

  In this way, by making the elastic material 11 into a rubber woven fabric, the elastic material 11 can be expanded / contracted only in the longitudinal direction of the upper belt 10 and not expanded in the short direction of the upper belt 10. Become. Therefore, it is possible to increase the tensile strength of the stretchable material 11 while maintaining the stretchability of the stretchable material 11. Moreover, not only the stretchable material 11 is not easily deteriorated by sunlight or rainwater, but also the entire shoe can be washed with water.

  The length and elongation rate of the stretchable material 11 in the direction along the longitudinal direction of the upper belt 10 are not particularly limited as described above, but in the shoe of the first embodiment, the direction along the longitudinal direction of the upper belt 10 The length of the stretchable material 11 is about 10 mm, and the stretch rate of the stretchable material 11 in the direction along the longitudinal direction of the upper belt 10 is about 200%. For this reason, the upper belt 10 can extend about 10 mm as compared with the natural length.

  Further, the length of the stretchable material 11 in the direction along the short direction of the upper belt 10 (the length when the stretchable material 11 is a natural length) is a predetermined section formed by the stretchable material 11 in the upper belt 10. It depends on the width of the part other than α and is not particularly limited. However, if the length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is too short, it is difficult to ensure the strength of the stretchable material 11. For this reason, the length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is usually 10 mm or more. The length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is preferably 15 mm or more, and more preferably 20 mm or more.

  On the other hand, if the length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is too long, it may be difficult to impart desired stretchability to the stretchable material 11. Moreover, there is a possibility that the appearance of the shoes may be deteriorated. For this reason, the length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is usually 50 mm or less. The length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is preferably 45 mm or less, and more preferably 40 mm or less. In the shoe of the first embodiment, the length of the stretchable material 11 in the direction along the short direction of the upper belt 10 is slightly more than 30 mm.

  Furthermore, the thickness of the stretchable material 11 (thickness when the stretchable material 11 is a natural length. When the stretchable material 11 is made of woven fabric, the thickness specified in “JIS L 1018”) is used for shoes. Also, it differs depending on the thickness of the portion other than the predetermined section α formed of the stretchable material 11 in the upper belt 10 and is not particularly limited. However, if the stretchable material 11 is too thin, it is difficult to ensure the strength of the stretchable material 11. For this reason, the thickness of the stretchable material 11 is normally 0.5 mm or more. The thickness of the stretchable material 11 is preferably 0.8 mm or more, and more preferably 1 mm or more.

  On the other hand, if the stretchable material 11 is too thick, it may be difficult to impart desired stretchability to the stretchable material 11. Further, the stretchable material 11 becomes thicker than the thickness of the portion other than the predetermined section α in the upper belt 10, and the appearance of the shoes may be deteriorated. For this reason, the thickness of the stretchable material 11 is usually 4 mm or less. The thickness of the stretchable material 11 is preferably 3 mm or less, and more preferably 2.5 mm or less. In the shoe of the first embodiment, the thickness of the stretchable material 11 is about 1.5 mm.

1.2 Upper belt (parts other than the specified section α)
The root (base end) of the upper belt 10 may be arranged on the outer edge side of the upper 20 (side closer to the little finger of the wearer's foot). In this case, the tip of the upper belt 10 is the upper 20 It is arranged on the inner edge side (the side closer to the wearer's toe). Therefore, there is a possibility that the tip of the upper belt 10 may be easily detached from the upper 20 due to the other leg of the wearer coming into contact with the tip of the upper belt 10 during walking or the like. For this reason, in the shoe of the first embodiment, the root of the upper belt 10 is arranged on the inner edge side of the upper 20 as shown in FIG.

  A means for fastening the tip of the upper belt 10 to the upper 20 is not particularly limited. Examples of the means include a hook-and-loop fastener, a pin buckle, a plate buckle, a ring buckle, and a button. In particular, it is preferable to use a hook-and-loop fastener. The hook-and-loop fastener is not only easy to attach and detach, but also can continuously change the location where the tip of the upper belt 10 is fastened. Further, the hook-and-loop fastener is easy to come off compared to a pin buckle or the like, and the significance of adopting the configuration of the present invention is enhanced.

  Further, if the tip of the upper belt 10 and the upper 20 are fastened with a hook-and-loop fastener, the artificial belt will force when the front end of the upper belt 10 once comes off the upper 20 and returns to the initial position again. Even if it is not added, the tip of the upper belt 10 can naturally stay on the upper 20 with the momentum at that time. The shoe of the first embodiment is a surface fastener type in which a male surface fastener (not shown) is fixed to the outer surface of the upper 20 and a female surface fastener (not shown) is fixed to the inner surface of the front end of the upper belt 10. It has become.

  The material of the portion other than the predetermined section α formed of the stretchable material 11 in the upper belt 10 varies depending on the use of the shoe and is not particularly limited. Various materials generally used for the upper belt 10 can be used for portions other than the predetermined section α in the upper belt 10. Specific examples include synthetic leather, natural leather, synthetic resin, natural resin, and woven or non-woven fabric made of synthetic fiber or natural fiber.

  In the shoe of the first embodiment, the base end portion 12 of the upper belt 10 and the front side edge portion 13 of the front end portion of the upper belt 10 are formed of synthetic leather, but the rear side of the front end portion of the upper belt 10 The edge 14 is formed by covering a thick, woven fabric that is flexible and elastic with a mesh sheet. When the shoe is put on or taken off, or when walking, the wearer wears the belt 14 from the upper belt 10. The excessive pressure is not applied to the instep.

1.3 Belt Threading The belt threading 30 is provided in the upper belt 10 in a state that does not inhibit the movement of the upper belt 10 in the longitudinal direction (a state in which the expansion and contraction of the elastic material 11 in the direction along the longitudinal direction of the upper belt 10 is not inhibited). If it is a thing of the form which can let a desired location pass, it will not specifically limit. For example, the belt loop 30 may be formed by providing a pair of parallel slits on the upper 20 at a predetermined interval.

  In the shoe of the first embodiment, as shown in FIG. 2, the belt loop 30 has a width of the elastic material 11 in the upper belt 10 (the length of the elastic material 11 in the direction along the short direction of the upper belt 10). In a state in which the belt-like material 31 having a longer length is overlapped so as to be substantially perpendicular to the upper belt 10, both ends of the belt-like material 31 are sewn to the upper 20 (sewn portions P, It is formed by sewing with Q).

  Thus, by forming the belt loop 30 with the belt-shaped material 31, it becomes possible to form the belt loop 30 after fixing the base end of the upper belt 10 to the upper cover 20. Even if the width of the belt 10 is wide or the tip of the upper belt 10 is thick, a desired portion of the upper belt 10 can be easily passed through the belt loop 30.

  Therefore, a portion other than the predetermined section α in the upper belt 10 is made wider than the predetermined section α, and a portion other than the predetermined section α in the upper belt 10 is made thicker than the predetermined section α, and is formed by the belt loop 30. It is also possible for the loop to have a dimension that allows only a predetermined section α of the upper belt 10 to pass through. For this reason, even if it is intentional, it becomes possible to prevent the leading end of the upper belt 10 from being pulled out from the belt loop 30 to the proximal end side.

  The thickness of the belt-shaped material 31 that forms the belt loop 30 is not particularly limited. However, if the strip 31 is made too thin, the strength of the belt thread 30 may not be maintained. Further, the difference in stress generated between the front and back of the upper belt 10 (the elastic material 11 in the shoe of the first embodiment) folded at the upper edge of the belt loop 30 (bent portion) is reduced, and the upper belt 10 is naturally There is also a risk that it will be difficult to return to the initial position. For this reason, the thickness of the strip | belt-shaped material 31 shall be 0.3 mm or more normally. The thickness of the strip-shaped material 31 is preferably 0.5 mm or more, and more preferably 0.7 mm or more.

  On the other hand, if the belt-like material 31 forming the belt loop 30 is too thick, the surface of the belt-like material 31 is the surface of the portion other than the predetermined section α of the upper belt 10 when the tip of the upper belt 10 is fastened to the upper 20. The shape of the shoe protrudes more outward than the shoe, and the appearance of the shoe may deteriorate. For this reason, the thickness of the strip-shaped material 31 is normally 5 mm or less. The thickness of the strip-shaped material 31 is preferably 4 mm or less, and more preferably 3 mm or less. In the shoe of the first embodiment, the thickness of the belt-like material 31 is about 1 mm.

  Further, the material of the belt-like material 31 forming the belt loop 30 is not particularly limited. In the shoe of the first embodiment, the belt-like material 31 is formed of the same synthetic leather as the base end portion 12 of the upper belt 10 and the front side edge portion 13 of the distal end portion of the upper belt 10. Thus, by using the material used for the upper belt 10 for the belt-shaped material 31, it is possible to make the upper belt 10 simple and give a sense of unity to the design of the shoe.

1.4 Other For the parts other than those described above, such as the upper 20 in the shoe of the first embodiment, various configurations adopted in general shoes are adopted unless they are contrary to the spirit of the present invention. be able to.

1.5 Operation of Upper Belt Next, the operation of the upper belt 10 will be described. In the shoe of the first embodiment, in a state where the tip of the upper belt 10 is fastened to the upper 20 (a state where the upper belt 10 is closed), the stretchable material 11 has an outer surface as shown in FIG. It is pressed down by the belt-like material 31 of the belt loop 30, and the whole is in a state along the upper 20.

  When the wearer runs around from the state shown in FIG. 3, the tip of the upper belt 10 is detached from the upper 20 and the front side of the upper belt 10 is folded back to the proximal side of the upper belt 10. As shown, the stretchable material 11 extends more than the state of FIG. 3, and the distal end side of the stretchable material 11 is also folded back to the proximal end side of the upper belt 10. At this time, the upper belt 10 or the stretchable material 11 is supported by the upper edge of the belt-like material 31 of the belt loop 30, and the tip side of the upper belt 10 is not lowered any more when it is folded to some extent. .

  In the state shown in FIG. 4, since the stretchable material 11 is in a state of being stretched more than the natural length, the stretchable material 11 is subjected to stress that tends to shrink. However, at the portion (bent portion) of the stretchable material 11 that is bent at the upper edge of the strip-shaped material 31, the back surface of the stretchable material 11 (the surface that faces the upper 20 in the state of FIG. 3) is the stretchable material. 11 is in a state of extending more greatly than the surface of 11 (the surface facing the belt-like material 31 in the state of FIG. 3).

  For this reason, in the said bending part of the elastic material 11, the stress (arrow b in FIG. 4) which is going to shrink | contract the back surface side of the elastic material 11 is the stress (in FIG. 4) which is going to shrink the surface side of the elastic material 11 It is larger than the arrow a). Due to the difference in stress generated between the front and back of the stretchable material 11, the stretchable material 11 returns to the state shown in FIG. At this time, the front end side of the upper belt 10 also moves in the direction of the arrow c shown in FIG. 4 and naturally returns to the initial position.

  The tip of the upper belt 10 that has returned to the initial position collides with the upper 20 by the momentum at that time. Therefore, the female hook-and-loop fastener provided at the tip of the upper belt 10 and the male hook-and-loop fastener provided at the upper 20 are entangled and fixed again. As described above, in the shoe of the first embodiment, even if the tip of the upper belt 10 is once detached from the upper 20, the upper belt 10 is returned to the initial position again, and the front of the upper belt 10 is naturally moved to the upper 20. It is possible to stay in.

2.0 Shoes of Second Embodiment Subsequently, another embodiment (second embodiment) of the shoe of the present invention will be described. FIG. 5 is a perspective view showing another embodiment (second embodiment) of the shoe of the present invention. In FIG. 5, only the shoe for the right foot is illustrated, but the shoe for the left foot can adopt a configuration that is symmetrical to the shoe for the right foot.

  As shown in FIG. 5, the shoe of the second embodiment includes an upper belt 10 for adjusting the tightening state of the upper, and a predetermined section α in the vicinity of the base (base end) of the upper belt 10 is an elastic material 11. It has been formed. A belt loop 30 for passing the upper belt 10 is formed on the outer surface of the upper 20, and a part of the front end side of the predetermined section α formed of the stretchable material 11 in the upper belt 10 is a belt loop 30. It is in a state covered by.

  The difference in stress described in “1.5 Operation of the upper belt” can also occur in a portion of the upper belt 10 other than the predetermined section α (portion not formed of the stretchable material 11). In addition, if a part of the front end side of the upper belt 10 than the predetermined section α formed by the stretchable material 11 is covered with the belt loop 30, even if the front end of the upper belt 10 is detached from the upper 20, It is possible to return the upper belt 10 to the initial position again, and to naturally keep the tip of the upper belt 10 on the upper 20.

  In the shoe of the second embodiment, with respect to the other configurations, a configuration substantially the same as that of the shoe of the first embodiment can be adopted, and thus description thereof is omitted.
