The heel counter 7 includes: a sole 71 of the lower heel part oppositely facing the user's sole; and a heel side-wall part 72 that rises from the circumference or the neighborhood of the sole 71 of the lower heel part. The heel counter 7 is configured such that a rear lower end part 7rd of the heel counter 7 close to a rear end 2r of a sole 2 is connected to the sole 2 or an upper 4, with a connection part 8 as a pivot, with an angle constantly held which is formed by the sole 71 of the lower heel part and the heel side-wall part 72, and with the heel counter 7 made rotatable. The heel counter 7, when the shoe is worn, becomes an erected state, with the sole 71 of the lower heel part paralleled to the sole 2 thereon and, when the shoe is not worn, the heel counter 7 is rotated from the erected state and becomes tilted by making the heel side-wall part 72 tilted backward.

Description

  The present invention relates to a shoe having a heel portion that wraps the heel when worn.

  When a shoe having a heel is worn, the rear upper end of the heel covering the back of the heel may interfere with the user's foot, making it difficult to insert the foot through the mouth. In order for the user to wear such hard-to-wear shoes, take a crouched posture and widen the mouth before inserting the foot by pulling the rear upper edge of the heel of the shoe backward with a finger, etc. It is necessary and it takes time to wear shoes. In particular, shoes such as leather shoes having a relatively hard heel part are difficult to pull the heel part to widen the mouth, and it is often the case that difficulty in wearing becomes a problem. In addition, when elderly people try to wear such shoes that are difficult to wear, there is a risk that the balance may be lost and the bicycle may fall over.

  For example, Patent Document 1 describes a shoe configured to be movable in a direction away from a heel of a foot on which a part of the heel is worn. The heel portion configured to be movable is configured to be slidable using a substantially center in the front-rear direction of the shoe as a fulcrum fulcrum, and includes a so-called moon-shaped portion that covers the outer side surface and the inner side surface and the back surface of the user heel However, it does not have a part that supports the heel from the sole side. Patent Document 2 describes a shoe in which a heel portion is cut into a slipper type. Before wearing these slipper type shoes, both sides of the instep open and fall back with the buttocks into a slipper shape.If you put the buttocks back after wearing them, both sides of the instep will also be based It is made to return, and both sides of the buttocks and the instep can be fixed with Velcro (registered trademark).

  Further, in Patent Document 3, in a shoe having a shoe sole that supports the user's foot from below and an upper that covers the user's foot from the side and from above, the upper part and the upper heel part of the upper are separated, The shoe sole is folded at the front and rear center to make it easy to insert the foot when not worn, and is shaped like a hem, and the shoe sole is elastic so that it becomes flat due to elastic deformation due to body weight after the foot is inserted. Is given. The upper part and the upper part of the heel can be fastened by fastening means after the foot is inserted.

Japanese Patent Laid-Open No. 2007-152066 JP 2005-177394 A JP 2006-334359 A

  In the shoe described in Patent Document 1, the sole corresponding to the sole of the user when worn and the lunar part of the heel that can be swung are not integrated, and the portion that wraps the user's heel is integrated. Therefore, it is difficult to obtain a sense of unity with the user's feet, and the back surface of the heel is rubbed and is not easy to wear or walk. The slipper-type shoes described in Patent Document 2 are also inferior in the ability to follow the heel because the shape retention of the heel portion is insufficient. The shoe described in Patent Document 3 bends at the arch corresponding part corresponding to the arch of the user at the shoe sole, so that the basic performance of the shoe cannot be maintained. Usually, the arch corresponding part of the shoe sole is a part in which a reinforcing member called a shank is purposely incorporated so as not to be bent, and the shoe described in Patent Document 2 in which the arch corresponding part is bent is stepped on or kicked out while being worn. When the operation is performed, the shoe bottom portion may be bent unintentionally, and it is difficult to say that the safety is high. In the shoe described in Patent Document 3, it is only the fastening means between the upper part and the upper part of the heel in the upper that can prevent bending during use, and such a shoe structure is inferior in durability and has sufficient rigidity. Otherwise, the user's heel may be rubbed with a slightly moving heel, which may cause shoe rubs.

  The present invention relates to a shoe that has excellent heel followability and is easy to walk and wear.

  The present invention includes a shoe sole that supports a user's foot from below, and an upper that stands up from the periphery of the shoe sole or the vicinity thereof and covers the user's foot inserted from the mouth from the side and from above. A shoe having a foot pocket that is defined by the shoe sole and the upper and accommodates a user's foot, and a heel counter that wraps the user's heel is disposed in the foot pocket. The heel counter is configured to include a heel lower sole facing the sole of the user, and a heel side wall standing up from the periphery of the heel lower sole or in the vicinity thereof, at the rear end of the shoe sole. The rear lower end of the adjacent heel counter is connected to the shoe sole or the upper, and the angle formed between the heel lower sole and the heel side wall is kept constant with the connecting portion as a pivot. The heel counter is configured to be rotatable. When the heel counter is worn, the lower heel sole is parallel to the sole on the shoe sole and is in an upright state, and when not worn, the heel counter is rotated from the upright state. Thus, the shoe is tilted backward by tilting the heel side wall portion backward.

  The shoes of the present invention have excellent heel followability and are easy to walk and wear. Accordingly, the shoe of the present invention can be used with peace of mind by an elderly person who may fall over when wearing the shoe.

It is a figure of a back leaning state.

  Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. 1 to 3 show one side (for the left foot) of the first embodiment of the shoe of the present invention. In the following, one side (for the left foot) of the shoe of the present invention will be mainly described, but the following description is also applied to the other side (for the right foot) unless otherwise specified. The shoe 1A according to the first embodiment includes a shoe sole 2 that supports a user's foot from below, and a user's foot that is erected from the periphery of the shoe sole 2 or the vicinity thereof and inserted through the mouth 3 And an upper 4 covering from above, which is defined by the shoe sole 2 and the upper 4 and has a footrest portion 5 for accommodating a user's foot. The shoe sole 2 and the upper 4 are integrated with each other by joining means such as sewing and adhesive.

  The shoe sole 2 is a portion that covers the sole (sole) of the user, and has a size that can cover the entire sole of the user. The shoe sole 2 is configured to block penetration of moisture or oil adhering to the floor surface into the shoe, and may be a single layer structure or a multilayer structure. As an example of the shoe sole 2 having a multilayer structure, it is formed from an outsole constituting a ground contact surface (walking surface) and a flexible and cushioning material such as urethane foam, which is disposed on the upper surface side (the sole side) of the outsole. And a midsole (medium item). A predetermined uneven pattern is formed on the lower surface (not shown) of the shoe sole 2 serving as a ground contact surface, and even when walking on a slippery floor surface such as a wet floor surface while wearing the shoe 1A, it does not slip. The desired operation can be performed. The material of the shoe sole 2 is not particularly limited, and various conventionally used materials can be used, and examples thereof include rubber, synthetic resin, thermoplastic elastomer, natural, synthetic leather, and the like.

  As shown in FIG. 3, a shank 6 corresponding to the arch of the user in the shoe sole 2 is provided with a shank 6 as a reinforcing member, thereby suppressing deformation of the arch corresponding portion during wearing. The comfort of the shoe 1A is enhanced. The shank 6 is a plate-like member having a rectangular shape in plan view, and is fitted into the arch corresponding portion of the shoe sole 2. The shank 6 is made of a material that is higher in rigidity than the sole 2 and is usually made of a metal material such as steel.

  The upper 4 is a member that covers a portion of the user's foot that is located above the sole of the foot. In the first embodiment, the upper 4 has a bag shape that can cover the entire portion. As shown in FIGS. 2 and 3, the upper 4 includes an upper front portion 41 that covers the toes of the user's toes and the vicinity thereof, and a portion closer to the ankle in the foot table (foot back) (a portion located above the arch). ) And an upper rear portion 43 covering the back surface and the left and right side surfaces of the bag. The mouth 3 is defined by upper ends of the upper central portion 42 and the upper rear portion 43.

  The upper 4 can be formed by overlaying various parts that can be sewn. An example of the upper 4 includes an outer member that forms the outer surface of the shoe 1 </ b> A, an inner member that forms an inner surface that contacts the user's foot or sock, and a cushioning material disposed between the two members. . The material of the upper 4 is not particularly limited, and various conventionally used materials can be used, and examples thereof include natural or artificial leather, synthetic resin, and cloth.

  As shown in FIGS. 1, 2, and 4, a heel counter 7 that wraps the user's heel is disposed in the foot pocket 5. The heel counter 7 includes a plate-like heel lower sole 71 that faces the sole of the user, and a heel side wall portion 72 that stands up from the periphery of the heel lower sole 71. The heel lower sole 71 corresponds to the part from the rear end of the sole of the user to the front of the arch, and is longer in the front-rear direction (the left-right direction in FIGS. 2 and 3) than the shoe sole 2 corresponding to the entire sole. Is short. The heel side wall portion 72 has an outer wall portion 72a that covers the outer surface of the heel and an inner wall portion that covers the inner surface of the heel, with a portion corresponding to the back of the user's heel (the portion marked with a dotted line in FIG. 4) as a boundary. 72b. Both wall parts 72a and 72b each have a part where the standing height gradually decreases from the upper surface of the heel lower sole 71 toward the front side (toe side). In a side view of the heel counter 7 in the upright state as shown in FIG. 2A, the upper end surfaces 72s (see FIGS. 2 and 4) of the both side walls 72a and 72b are convexly curved upward. have. Further, in the side view of the heel counter 7 in the upright state as shown in FIG. 2A, a portion corresponding to the back surface of the user's heel in the heel side wall portion 72 and its vicinity (a portion indicated by a dotted line in FIG. 4) And its peripheral portion, the rear end portion of the heel side wall portion 72) has a convex curved shape toward the rear. Since each part of the heel side wall part 72 has such a curved shape, the heel counter 7 can hold the user's heel firmly. The heel lower sole 71 and the heel side wall portion 72 are fixed to each other, and the angle formed between them is always constant. The heel counter 7 may be one in which the separate heel lower sole 71 and the heel side wall 72 are joined together by a joining means such as sewing or adhesive, and the heel counter 7 and the heel side wall 72 may be integrated. And may be integrally formed.

  As shown in FIG. 2, the heel counter 7 is disposed in the footrest portion 5 so that the outer surface of the heel side wall portion 72 and the inner surface of the upper 4 (upper rear portion 43) are in contact with each other. The heel side wall portion 72 and the upper rear portion 43 may be integrated with each other by a joining means such as sewing or adhesive at all or part of the contact portion between them.

  The material of the heel counter 7 is preferably a material excellent in shape retention so that the heel counter 7 will not be deformed during use. For example, synthetic resin, leather, cured rubber, metal, and composites thereof may be used. Can be mentioned. The heel counter 7 can be made of a material having relatively high rigidity as compared with the upper rear portion 43 surrounding the heel counter 7. For example, the material of the heel counter 7 can be a synthetic resin, and the material of the upper rear portion 43 can be a fabric, leather, or the like.

  As one of the main features of the first embodiment, as shown in FIG. 2, the rear lower end 7rd of the heel counter 7 adjacent to the rear end 2r of the shoe sole 2 is connected to the shoe sole 2 or the upper 4 to connect the connecting portion. 8 is formed, and the heel counter 7 can be rotated above the shoe sole 2 while keeping the angle formed by the heel lower sole 71 and the heel side wall 72 constant with the connecting portion 8 as a pivot. The point which is comprised is mentioned. The rear lower end 7rd of the heel counter 7 may be connected to both the shoe sole 2 and the upper 4 or may be connected to only one of them, or between the shoe sole 2 or the upper 4 You may connect directly without passing through another member, and you may connect via another member. Further, the connection form of the heel counter 7 and the shoe sole 2 or the upper 4 is not particularly limited as long as both are integrated, and the separate heel counter 7 and the shoe sole 2 or the upper 4 are sewn together. Further, it may be a form integrated by a bonding means such as an adhesive, or a form in which the heel counter 7 and the shoe sole 2 or the upper 4 are integrally formed. In the first embodiment, as shown in FIG. 2, the rear lower end portion 7rd of the heel counter 7 is connected to both the shoe sole 2 and the upper 4 (upper rear portion 43). Are connected via fastening means 9 described later, and are directly connected to the upper rear portion 43 without any other member.

  In the shoe 1 </ b> A provided with such a rotatable heel counter 7, the heel counter 7 is configured such that the heel lower sole 71 is placed on the shoe sole 2 when the foot is accommodated in the foot pocket 5. The heel counter 7 is rotated from the upright state to tilt the heel side wall portion 72 backward when not worn, when the heel counter 7 is in an upright state (see FIGS. 1A and 2A). As a result, the vehicle is tilted backward (see FIGS. 1B and 2B). In the process of changing the heel counter 7 from the upright state to the rearward tilted state, the rear upper end portion 43ru (see FIG. 2) of the upper rear portion 43 that defines the wearer 3 is pushed by the heel side wall portion 72 and By tilting, the wearer mouth 3 expands in the front-rear direction, so the rearward tilted state of the heel counter 7 is larger than that of the upright state, so that the foot can be easily inserted from the wearer mouth 3 and shoes It is a wearable state in which 1A is easy to wear. In order to change the heel counter 7 from the upright state to the backward tilted state, when the foot is not accommodated in the footrest portion 5, the rear upper end portion 43ru of the upper rear portion 43 is grasped with a finger and pulled backward. It ’s fine. Further, in order to change the heel counter 7 from the rearward tilted state to the upright state, it is only necessary to insert the foot through the mouth 3 and step on the entire sole 2 with the sole as in the case of wearing normal shoes. In the rear tilt state of the heel counter 7, when the foot is inserted from the mouth 3 and the front end 71 f is lifted from the upper surface of the shoe sole 2, the heel lower sole 71 is stepped on with the heel. In the process of becoming parallel to the heel, the heel side wall portion 72 that is integrated with the heel counter 7 rises, so that the mouth 3 is contracted in the front-rear direction, and the heel counter 7 is in an upright state. The heel counter 7 can be changed from the rearward tilted state to the upright state by pushing the heel counter 7 to the front side by hand and turning it without wearing the shoes 1A.

  As described above, the shoe 1A is configured such that the shoe mouth 3 expands / contracts when the heel counter 7 rotates, but the shoe sole 2 and the heel counter 7 do not substantially deform during the expansion / contraction process. The angle formed by the lower sole 71 and the heel side wall 72 remains constant at all times. Accordingly, while the shoe 1A is being worn, the user's heel is firmly held by the heel counter 7 and the heel counter 7 follows the heel accurately. Lateral misalignment is prevented, kicking is less uncomfortable, and walking is easier.

  In the first embodiment, the upper rear portion 43 that surrounds the heel counter 7 in the upper 4 has elasticity in the front-rear direction of the shoe 1A. Accordingly, when the heel counter 7 is rotated from the upright state to the rearward tilted state, the upper rear portion 43 is pulled rearward by the heel side wall portion 72 and extended, and the rotation of the heel counter 7 is not hindered. Further, when the heel side wall portion 72 is rotated forward from the tilted state, the extended upper rear portion 43 contracts and the heel counter 7 returns to the upright state. In the first embodiment, only the upper rear part 43 has elasticity, and the other parts of the upper 4 (upper front part 41 and upper central part 42) do not have elasticity, Part or all of the part may also have elasticity. Examples of the material of the elastic upper 4 include cloth, leather, and synthetic resin. Since the upper according to the present invention is required to have stretchability as a preferable characteristic from the viewpoint of more reliably turning the heel counter as described above, the material thereof is stretchable cloth, synthetic leather. A stretchable material such as a rubber material is preferred, but the entire upper need not be stretchable. Even if most of the upper is a non-stretchable material that is substantially poorly stretchable (for example, made of leather), by using a stretchable material such as a rubber cloth or urethane foam for the other part of the upper, This is because it is possible not to disturb the rotation of the heel counter. By making the upper a composite structure of stretchable material and non-stretchable material, the device of the present invention (rotation of the heel counter) described above can be realized more reliably, while the degree of freedom of material selection is high. The appearance of the shoes can be made a highly fashionable design, for example, the appearance of orthodox men's shoes and women's shoes.

  As shown in FIGS. 1 and 2, between the heel lower sole 71 and the shoe sole 2, the heel lower sole 71 is attached to and detached from the shoe sole 2 in the upright state of the heel counter 7 as shown in FIG. Fastening means 9 for free fastening is provided. By providing such fastening means 9, the heel counter 7 constituting the heel counter 7 is fixed to the upper surface of the shoe sole 2 while the shoe 1A is being worn. The inconvenience of unintentionally turning the lower end portion 7rd (connecting portion 8) as a rotation support shaft is prevented, and the heel counter 7 does not flutter during walking, and the ease of walking is further improved. Examples of the fastening means 9 include a hook-and-loop fastener, an adhesive material that can be used repeatedly, a small metal snap, a magnet sheet, and the like. Among these, the hook-and-loop fastener is particularly preferably used in the present invention because it fits comfortably on the foot even when worn for a long time. In particular, a surface fastener having a resinous nail head structure, represented by 3M's dual lock fastener, is more preferable in terms of comfort and durability because it has sufficient strength and does not cause displacement.

  In the first embodiment, a hook-and-loop fastener is employed as the fastening means 9, and a loop surface 91, which is one surface of the hook-and-loop fastener, is provided on the lower surface of the heel lower sole 71. A hook surface 92 detachably coupled to the loop surface 91 is provided at a portion corresponding to the lower surface of the heel lower sole 71. On the contrary, a hook surface 92 is provided on the lower surface of the heel lower sole 71. The loop surface 91 may be provided in a portion corresponding to the lower surface of the heel lower sole 71 on the upper surface of the shoe sole 2. As shown in FIG. 2, the fastening means 9 which is a hook-and-loop fastener includes two plate-like members 93 and 94 facing each other, and these two plate-like members 93 and 94 are connected at their ends. The inner surfaces of the two plate-like members 93 and 94 are configured such that the inner surfaces of the connecting portions 95 are pivoted so as to be able to contact and separate. One is a loop surface 91 and the other is a hook surface 92. The fastening means 9 (plate-like members 93 and 94) are sewn, glued or the like on the lower surface of the heel lower sole 71 and the upper surface of the shoe sole 2 with the connecting portion 95 close to the rear end 2r of the shoe sole 2. The two support members 93 and 94 are pivoted so as to be able to contact and separate in conjunction with the pivoting of the heel counter 7.

  As shown in FIGS. 1 and 2, the foot holder 5 is interposed between the sole 2 and the heel lower sole 71 and the sole of the user when worn, and the entire sole of the user (the sole 2). An insole 10 (inner sole) having a size capable of covering the entire upper surface) is disposed. The insole 10 is fixed to the heel counter 7 by joining means such as sewing and adhesive, and is not fixed to other components (shoe sole 2, upper 4) of the shoe 1A other than the heel counter 7. The insole 10 prevents the heel counter 7 from rotating. More specifically, the insole 10 is disposed in the footrest portion 5 so as to cover the upper surfaces of the shoe sole 2 and the heel lower sole 71 and is in contact with the heel counter 7 (on the sole of the user's foot). All or a part of the insole rear portion corresponding to the heel side is fixed to the heel counter 7 (the upper surface of the heel lower sole 71 and / or the inner surface of the heel side wall portion 72), and other portions other than the fixing portion (use The front part of the insole corresponding to the toe side of the sole of the person and the portion near the front part of the insole in the center part of the insole corresponding to the arch) are fixed to other shoe constituent members constituting the shoe 1A. Not a fixed part.

  The front end 10f of the insole 10 is located at substantially the same position as the front end 5f of the footrest portion 5 as shown in FIG. In the state, as shown in FIG. 2 (b), the rear portion of the insole 10 (the contact portion with the heel counter 7) is pushed up by the heel lower sole 71, thereby retreating from the position in the wearable state. When the heel counter 7 is rotated from the rearward tilted state and the rearward tilted heel side wall portion 72 is raised to the front side, the front end 10f of the insole 10 moves forward from the position in the rearward tilted state, 5 returns to substantially the same position as the front end 5f. As described above, in the first embodiment, the insole front portion (the front end 10f and the vicinity thereof) is movable in the front-rear direction of the shoe 1A as the heel counter 7 rotates.

  2B, the insole front portion (the front end 10f and the vicinity thereof) is in contact with the upper surface of the shoe sole 2, and the insole 10 is bent at the center portion in the front-rear direction. Alternatively, the state of the insole 10 in the rearward tilted state is not limited to this, but the front portion of the insole is lifted from the upper surface without contacting the upper surface of the shoe sole 2 and is in contact with the inner surface of the upper 4 There may be a state or a state where the insole front part is located in a space part between the upper surface of the shoe sole 2 and the inner surface of the upper 4. The difference in the state of the insole 10 in the rearward tilt state of the heel counter 7 is greatly affected by the material of the insole 10, and by appropriately selecting the material of the insole 10, the insole in the non-wearing state 10 can be in a desired state. The material of the insole 10 is not particularly limited, and various conventionally used materials can be used, which can suitably correspond to the shape of the sole of the user and can reduce the impact during walking. Those having cushioning properties and required hygroscopicity are preferably used. Specific examples of the material for the insole 10 include synthetic resin, non-woven fabric, metal, and foamed rubber molded product. In addition, it is not necessary to combine the insole 10 with an auxiliary member such as cloth, paper, or a non-woven fabric made of another material so as to give the insole 10 hygroscopicity or appropriate lubrication because it is not related to the essence of the present invention. You can use it.

  FIG. 5 shows one side (for the left foot) of the second embodiment of the shoe of the present invention. In the second embodiment, components that are different from those of the first embodiment described above will be mainly described, and the same components will be denoted by the same reference numerals and description thereof will be omitted. The description of the first embodiment is appropriately applied to components that are not particularly described.

  In the shoe 1 </ b> B of the second embodiment, as shown in FIG. 5, a leaf spring-like elastic member 11 is disposed between the heel lower sole 71 and the shoe sole 2. The plate spring-like elastic member 11 has a vertically long shape in the front-rear direction of the shoe 1B in plan view, and the length in the front-rear direction (longitudinal direction) is longer than the length in the front-rear direction of the heel lower sole 71, It is shorter than the length of the shoe sole 2 (insole 10) in the front-rear direction. The leaf spring-like elastic member 11 has a front extending portion 11E that is fixed to the lower surface of the heel lower sole 71 by a joining means such as sewing and adhesive, and extends forward from the front end 71f of the heel lower sole 71. ing. The front extending portion 11E of the leaf spring-like elastic member 11 is not fixed to other components (shoe sole 2, upper 4, insole 10) of the shoe 1B. Fastening means 9 is fixed between the leaf spring elastic member 11 and the shoe sole 2, and a loop surface 91 arranged on the lower surface side of the spring elastic member 11 is arranged on the upper surface side of the shoe sole 2. By fixing to the hook surface 92, the heel lower sole 71 can be detachably fixed to the shoe sole 2 via the spring-like elastic member 11.

  As shown in FIG. 5B, the leaf spring-like elastic member 11 is in a natural state (a state in which no external force is applied), and the front and rear direction center portions thereof are the front end 11 f and the rear end of the leaf spring-like elastic member 11. When the leaf spring-like elastic member 11 is in a curved state (natural state) so as to be positioned above each of 11r, the heel counter 7 is tilted backward as shown in FIG. 5 (b). Has been made to realize. Then, as shown in FIG. 5 (a), when the foot is received and worn in the foot putting part 5 of the shoe 1B (when the heel counter 7 is in the upright state), the leaf spring-like elastic member 11 is used. When the weight of the user is applied, the curved state of the leaf spring-like elastic member 11 is eliminated, and the whole leaf spring-like elastic member 11 is in a flat state along the shoe sole 2 and the leaf spring-like elastic member. 11, an urging force for pushing up the heel lower sole 71 (the front end 71f of the heel lower sole 71 and the vicinity thereof) is generated. The upward biasing force of the leaf spring-like elastic member 11 is maintained as it is while the shoe 1B is worn, and the leaf spring-like elastic member 11 remains flat without being curved. When the user takes off the shoe 1B (when the sole of the user leaves the upper surface of the insole 10), the force to step on the leaf spring-like elastic member 11 is weakened, so that the leaf spring-like elastic member 11 is curved in a natural state. At this time, the heel lower sole 71 is pushed up by the urging force, whereby the heel counter 7 is rotated to be in a backward inclined state as shown in FIG. Thus, according to the shoe 1B of the second embodiment, the action of the leaf spring-like elastic member 11 can be performed only by removing the shoe 1B from the worn state (the upright state of the heel counter 7). Since the heel counter 7 is automatically shifted to the backward tilted state, it does not take time and labor to shift from the wearable state to the non-wearing state, and is excellent in operability.

  Although the present invention has been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate. For example, the upper 4 includes fasteners such as shoelaces, and the inside of the upper 4 (a portion covering the inner surface of the user's foot) and the outside (a portion covering the outer surface of the user's foot) in the vicinity of the mouth 3. It may be possible to tighten so as to be in close contact with the foot. All the parts of only the one embodiment described above can be used together as appropriate.

  Moreover, in the said embodiment, although the upper 4 was carrying out the bag shape which can coat | cover the whole part located above a sole in a user's foot, it covers only a part of this part. Alternatively, only a part of the upper front portion 41, the upper central portion 42, and the upper rear portion 43 may be provided. For example, the upper 4 has the upper front portion 41 or the upper central portion 42, but may not have the upper rear portion 43 that covers the back surface and the left and right side surfaces of the bag. In this case, the heel counter 7 is always exposed. It will be in the state.

  In the shoe 1 </ b> A of the first embodiment, the insole 10 may have the same elasticity as the leaf spring-like elastic member 11.
