Of the cross-sectional shape in the direction, at least a part of the heel support portion protrudes in the direction of the shoe sole base.

  Preferably, the insole further includes a plurality of insoles installed on the sole base and having different ratios of the height of the heel to other regions.

  According to the present invention, cushioning properties can be improved.

It is an assembly drawing which illustrates typically shoes 1 concerning this embodiment. It is an exploded view which illustrates the composition of shoes 1 concerning this embodiment. 2 is a diagram illustrating a configuration of a midsole 2. FIG. It is a figure which illustrates the structure of the heel support part. It is a figure which illustrates insole 40. FIG. It is a figure explaining the cross-sectional shape at the time of the combination of the midsole 2 and the heel support part 20. FIG.

The background according to the present embodiment will be described.
For example, the shoe is generally composed of an upper that wraps the entire foot and a sole that is a sole portion. The sole includes an insole (midsole) that supports the sole of the wearer and protects the foot from an impact by an elastic force, and an outsole that has gripping properties for capturing the ground. However, depending on the wearer, there is a risk of pain in the foot and joints due to insufficient cushioning of the sole.
On the other hand, in order to make up for the lack of cushioning properties, the sole has a toe by separately forming a toe support member that supports the vicinity of the wearer's toe and a heel support member that supports the vicinity of the wearer's heel on the midsole. It compensated for cushioning between the vicinity and the vicinity of the heel. However, in order to obtain more cushioning properties, it is difficult to change the configuration of the toe support member and the heel support member by deviating from the shape and elasticity of the shoes that are easy for the wearer to use.

Therefore, the shoe sole and shoes according to the present embodiment partially protrude the heel support member in the direction of the midsole out of the cross-sectional shape when the midsole and the heel support member are combined.
The shoe sole according to the present embodiment is configured to include a shoe sole base that supports the sole and a heel support portion that supports the vicinity of the heel of the shoe base portion, and the cross-sectional shape in the width direction of the heel support portion is a shoe. By projecting in the direction of the bottom base, it is convex upward. In addition, the shoe sole has a concave shape because the cross-sectional shape in the width direction of the shoe sole base is recessed in the direction of the heel support portion at a position facing the heel support portion. Further, the heel support portion has a peripheral region including a convex shape upward, and the height of the region excluding the peripheral region of the heel support portion is 1.5 of the height of the peripheral region of the heel support portion. It is twice or twice as high. The shoe sole further includes an arch support portion that supports the vicinity of the arch of the shoe sole base, and the heel support portion is made of a material that is more elastic than the arch support portion.
As described above, the shoe sole can further increase the cushioning property by forming the heel support portion in a convex shape in the direction of the shoe base and providing a peripheral region including the protruding portion. I can expect. In addition, the shoe sole is shaped so that the cross-sectional shape in the width direction of the shoe sole base at the position facing the heel support portion is recessed toward the heel support portion, so that the elasticity of the portion protruding into the convex shape of the heel support portion is obtained. It can be expected to convey the sex to the wearer more.

Further, the shoe according to the present embodiment is configured to include a shoe base that supports the sole and a heel support that supports the vicinity of the heel of the shoe base, and the shoe support and the shoe base are combined. Of the cross-sectional shape in the width direction of the case, at least a part of the heel support portion protrudes in the direction of the shoe sole base. Moreover, it has several insoles which are installed in piles on the sole base, and differ in the ratio of the height of the heel with respect to another area | region.
In this way, since the shoe is configured such that at least a part of the heel support portion protrudes in the direction of the shoe sole base, the elasticity of the protruding portion of the heel support portion can be transmitted to the wearer more. , Cushioning can be further increased.
Moreover, the shoe can adjust the cushioning property of the heel portion by installing an insole with a different heel height than the other regions on the shoe.

Next, a configuration according to the present embodiment will be described.
Hereinafter, the configuration of an embodiment according to the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples. Specifically, the shoe sole and the shoe according to the present embodiment are not necessarily limited to a shoe having a continuous surface-shaped upper covering portion or a shoe sole intended to be provided in the shoe. For example, footwear having a strap-like, belt-like, or net-like upper covering like a sandal, or a shoe sole intended to be provided in the footwear is also included in the technical scope of the present invention. Shall be. In addition, even footwear that has been separated by fingers, such as tabi or sandals, or a shoe sole intended to be provided for the footwear is also included in the technical scope.
Further, in this embodiment, for the sake of convenience of explanation, the description will be focused on the shoe sole or shoe for the left foot, but the left foot and the right foot are substantially bilaterally symmetrical, and the same configuration as the left foot is adopted for the right foot. Shall be able to.

[Shoe 1]
FIG. 1 is an assembly diagram schematically illustrating a shoe 1 according to this embodiment.
As illustrated in FIG. 1, the shoe 1 is generally composed of an upper and a sole.
The upper is a portion excluding the sole (sole) in the shape of the shoe and is a portion covering the instep. The upper keeps the foot in close contact with the sole so as to protect the foot from changes in external weather (heat, cold, rain, etc.) and impact, and to eliminate the gap between the foot and the shoe during walking. . Further, the upper needs to select a material in consideration of the physiological condition of the foot, and a material that absorbs and reduces moisture is preferable. The upper is preferably made of a stretchable material that takes into account changes in the foot volume due to fatigue or the like.

The sole is a portion of the shoe shape excluding a portion (upper) covering the instep, and is a shoe sole portion. The sole protects the foot from impacts caused by road surface irregularities and the like, and from hazards such as nails and glass. The sole is preferably made of a material that has excellent flexibility so that walking can be performed smoothly, is not easily consumed, and is difficult to slip. For example, the sole is made of an elastic member.
The sole is composed of an elastic member, and specifically, synthetic rubber, natural rubber, flexible resin, or the like can be used. In particular, the sole is preferably made of a thermoplastic flexible resin such as ethylene-vinyl acetate copolymer (EVA) or an elastic member such as polyurethane thermoplastic elastomer (TPU) as a material for the sole. As long as the sole is a material that can be used for a shoe sole, the material is not limited thereto, and a material can be selected as appropriate.

FIG. 3 is a diagram illustrating the configuration of the midsole 2.
FIG. 3A is a perspective view of the midsole 2.
As illustrated in FIG. 3A, the midsole 2 has a surface (midsole upper end surface portion 6) that has a gentle, substantially S shape in order to support a wearer's foot. Specifically, the midsole upper end surface portion 6 includes a midsole toe portion 6a, a midsole arch portion 6b, and a midsole heel portion 6c.
The midsole 2 is formed in a gentle substantially downward inclined surface that continues from the midsole front end 4a to the midsole toe portion 6a that supports the vicinity of the wearer's toe and the midsole arch portion 6b that supports the vicinity of the arch of the foot. . Further, the midsole 2 is formed so as to turn from a substantially downward inclined surface to a substantially upward inclined surface in the vicinity of the midsole arch portion 6b that supports the wearer's arch vicinity.
The midsole 2 reduces the collapse of the arch shape of the foot from the vicinity of the toe of the wearer to the vicinity of the arch by a continuous gentle inclined surface from the midsole front end 4a to the vicinity of the midsole arch 6b. In addition, assistance for maintaining the arch shape can be performed.

Further, the midsole 2 is formed in a continuous, substantially upward inclined surface from the midsole arch portion 6b to the midsole heel portion 6c that supports the vicinity of the heel of the wearer's foot and the midsole rear end portion 4b. The The midsole 2 is formed to be a substantially flat surface from the vicinity of the midsole collar 6c to the midsole rear end 4b.
The midsole 2 has the shape of the foot from the vicinity of the arch of the wearer's foot to the vicinity of the heel by the gentle, substantially upward inclined surface extending from the vicinity of the midsole arch 6b to the rear end 4b of the midsole. Helps to reduce and maintain the arch shape.

  Therefore, the midsole 2 can assist the wearer's foot into a correct arch shape by the continuous gentle inclined surface formed by the midsole upper end surface portion 6. Moreover, the midsole 2 can correct | amend the cushioning property with which a leg | foot is equipped by assisting a wearer's leg | foot so that it may become a correct arch shape. In other words, the midsole 2 can reduce the burden on the joint and the like by keeping the wearer's foot in the correct arch shape.

FIG. 3B is a bottom view of the midsole 2.
As illustrated in FIG. 3A and FIG. 3B, the midsole 2 has a midsole lower end surface portion 8 on the back surface side (side to the outsole 30) of the midsole upper end surface portion 6. The midsole lower end surface portion 8 includes a midsole toe portion 8a, a midsole arch portion 8b, and a midsole ridge portion 8c.
The midsole 2 includes a midsole toe portion 8a having a shape that fits into a shape of a toe support portion 10 described later.
The midsole 2 passes through the midsole toe portion 8a from the midsole front end portion 4a, and is formed in a gentle substantially downward inclined surface from the midsole arch portion 8b.

The midsole arch portion 8b is an example of an arch support portion according to the present invention.
The midsole arch portion 8b supports the vicinity of the arch of the wearer's sole. The midsole arch portion 8b is configured to protrude downward from the midsole toe portion 8a and the midsole flange portion 8c. Moreover, as illustrated in FIG. 3B, the midsole arch portion 8b is configured to have a substantially fan-shaped lower end surface. Specifically, the midsole arch portion 8b is formed in a substantially fan shape so that the length of the outer curve where the small heel is located is longer than the length of the inner curve where the heel is located. The lower end surface of the midsole arch portion 8b is formed in a substantially fan shape because the height and range of the arch of the arch on the heel side of the wearer and the foot side of the foot are different.
Further, the midsole arch portion 8b is configured so that the lower end surface is substantially flat. For this reason, the midsole arch portion 8b can support the weight of the wearer. The midsole arch portion 8 b is made of a material harder than the toe support portion 10 and the heel support portion 20. In other words, the toe support part 10 and the heel support part 20 are members that are softer and more elastic than the midsole 2. The midsole arch portion 8b functions as a fulcrum so that the wearer can move without trouble when the weight moves from the heel side to the toe side. Therefore, when a wearer moves from the heel side to the toe side, the wearer can move the weight naturally without difficulty. Midsole arch part 8b can change a shape and hardness suitably according to a wearer.
Here, as illustrated in FIG. 2 and FIG. 3, the midsole 2 of the present embodiment exemplifies a configuration that is integrated with the midsole arch portion 8 b that supports the arch, but is not limited thereto. Alternatively, the midsole 2 may be configured and combined separately from the midsole arch portion 8b.

FIG. 3C is an end view of the midsole 2 taken along the line AA.
As illustrated in FIG. 3, the midsole 2 includes a midsole collar 8 c having a shape that fits into the shape of a collar support 20 described later. Moreover, the midsole 2 has the peripheral part 8d in the periphery of the midsole collar part 8c. The midsole 2 is formed on a gently inclined surface from the peripheral edge 8d to the midsole rear end 4b.
Further, as illustrated in FIGS. 3B and 3C, the midsole 2 is, for example, substantially hemispherical (substantially dome-shaped) from the inner edge of the peripheral edge 8 d to the midsole flange 8 c. It is processed so that it becomes a concave shape. The midsole 2 is configured such that the midsole heel portion 8c and the heel support portion upper surface portion 20c are fitted together, and the peripheral edge portion 8d and the peripheral edge portion 20e are fitted together.

[Toe support 10]
As illustrated in FIGS. 1 and 2, the toe support unit 10 supports the vicinity of the wearer's toe. The toe support part 10 can be appropriately changed as long as it has a shape capable of supporting the vicinity of the wearer's toe. As illustrated in FIG. 1, the toe support portion 10 is formed in a shape that fits the top surface portion 10 c of the toe support portion into the midsole toe portion 8 a. The toe support 10 is a softer and more elastic member than the midsole 2 including the midsole arch 8b.
Further, as illustrated in FIG. 2, the toe support portion 10 is formed to be curved from the toe support portion front end portion 10 a to the toe support portion rear end portion 10 b. Further, when combined with the midsole 2, the toe support unit 10 is formed such that the toe support unit lower surface portion 10d and the midsole arch portion 8b are smoothly continuous. The toe support part 10 is formed with the toe support part lower surface part 10d so as to be smoothly connected to the midsole arch part 8b, thereby reducing the impact at the time of weight transfer from the wearer's arch vicinity to the toe side. Stability can be achieved.

[踵 support part 20]
FIG. 4 is a diagram illustrating the configuration of the heel support 20.
FIG. 4A is a perspective view of the heel support portion 20, and FIG. 4B is a left side view of the heel support portion 20. FIG. 4C is a plan view of the heel support portion 20, and FIG. 4D is a right side view of the heel support portion 20.

The heel support portion 20 is an example of a heel support portion according to the present invention.
As illustrated in FIGS. 1 and 2, the heel support portion 20 is attached to the midsole 2 at positions that become the midsole heel portion 8 c and the peripheral edge portion 8 d. The heel support portion 20 is a member that is softer and more elastic than the midsole 2 including the midsole arch portion 8b.
Further, as illustrated in FIG. 4, the heel support portion 20 includes a heel support portion front end portion 20a, a heel support portion rear end portion 20b, a heel support portion upper surface portion 20c, a heel support portion lower surface portion 20d, and a peripheral edge portion 20e.

The heel support portion 20 is curved and formed from the heel support portion front end portion 20a to the heel support portion rear end portion 20b. The heel support portion 20 is smoothly formed from the heel support portion front end portion 20a through the heel support portion lower surface portion 20d to the heel support portion rear end portion 20b.

The heel support portion 20 is formed such that the heel support portion upper surface portion 20c protrudes into a convex shape. Specifically, the heel support portion 20 is formed to protrude in a substantially hemispherical shape (substantially dome shape). Since the heel support portion 20 protrudes in a substantially hemispherical shape, the heel support portion 20 is formed so as to protrude not only in the direction from the heel support portion front end portion 20a to the heel support portion rear end portion 20b but also in the width direction.
Further, the height of the heel support portion 20 from the heel support portion lower surface portion 20d to the heel support portion upper surface portion 20c is about 1.5 times to about 2 times the height from the heel support portion lower surface portion 20d to the peripheral edge portion 20e. It is double the height. Specifically, the heel support portion 20 has a height of 1.8 cm at the highest portion of the height from the heel support portion lower surface portion 20d to the peripheral edge portion 20e, and the heel support portion lower surface portion 20d supports the heel support. The height of the highest part among the height to the part upper surface part 20c is 2.8 cm.
In this way, the heel support portion 20 can receive the pressure from any direction by making the heel support portion upper surface portion 20c project in the width direction, so that the cushioning property in the vicinity of the heel can be obtained. It can be further increased.

In addition, the heel support portion 20 is provided with a peripheral edge portion 20e so as to include the heel support portion upper surface portion 20c. The peripheral portion 20e is an example of a peripheral region according to the present invention.
The peripheral edge portion 20e has a width of 5 mm to 15 mm, for example. The shape of the peripheral portion 20e can be changed as appropriate as long as the peripheral portion 20e is fitted to the peripheral portion 8d.
As described above, the heel support portion 20 includes not only the heel support portion upper surface portion 20c but also the pressure applied from the vicinity of the heel of the wearer by arranging the peripheral edge portion 20e so as to include the heel support portion upper surface portion 20c. It can also be received at the peripheral edge 20e. In addition, the heel support portion 20 that is soft and raised at the center portion is combined with the harder midsole 2 so that the hardness at the heel center portion is lower than that of the heel peripheral portion. Thereby, stability can be given to a heel periphery part, ensuring sufficient elasticity in a heel center part, and improvement of durability and securing of walking stability can be expected.

[Outsole 30]
As illustrated in FIGS. 1 and 2, the outsole 30 is a part in contact with the floor surface of the shoe sole. The outsole 30 is also referred to as the outsole or the outsole. The outsole 30 is made of, for example, an elastic material, and specifically, is synthetic rubber, leather, urethane, wood, cork, jute or the like.
The outsole 30 is formed in a sheet shape, for example. The outsole 30 according to the present embodiment includes a midsole from the midsole front end 4a of the midsole 2 with the toe support 10 attached to the midsole toe 8a and the heel support 20 attached to the midsole heel 8c. It is attached so as to cover the rear end 4b.

  As described above, the shoe 1 includes the midsole 2, the toe support part 10, the heel support part 20, and the outsole 30.

[Insole 40]
FIG. 5 is a diagram illustrating the insole 40.
FIG. 5A is a perspective view illustrating the insole 40, and FIG. 5B is a diagram illustrating the insole 40a. FIG. 5C illustrates the insole 40b.
The insole 40 is an example of the insole according to the present invention.
As illustrated in FIG. 5A, the insole 40 is configured in a sheet shape. The insole 40 is a rug that has a portion in contact with the sole and is installed in a shoe.
The insole 40 is also called an insole or an inner sole. The insole 40 is also medically called, for example, a sole plate, a sole insert plate, or a straight insole.
In the present embodiment, the insole 40 is detachable and illustrated as an example to be inserted into the shoe 1. Moreover, although the case where the insole 40 is a flat insole having no concavo-convex shape is described, the present invention is not limited thereto, and may be a footbed insole having an concavo-convex shape. Further, the length of the insole 40 can be changed.
The insole 40 is made of, for example, a synthetic resin material, a synthetic fiber material, a leather material, a polyurethane material, or an activated carbon material. The insole 40 may be used for medical purposes for the treatment or correction of foot disease or deformation. In this case, for the medical insole 40, for example, cork is used.
The insole 40 is used to adjust the size of the shoe, but is not limited to this. For example, the heel for tightening the ankle for absorbing the shock and reducing the impact on the foot and the heel For lifting, hallux valgus measures, foot stuffiness measures to improve breathability in shoes, deodorization and deodorization, balance improvement to reduce knee and lower back pain, relief of strain and shock on the soles during exercise It can be applied to sports, O-leg / X-leg countermeasures for preventing O-leg / X-leg symptoms, or cold protection for preventing cold feet.

As illustrated in FIGS. 5B and 5C, the insole 40 is configured in a shape corresponding to the midsole upper end surface portion 6 of the midsole 2. Further, the insole 40 is configured so that the ratio of the height of the heel to other regions is different.
First, as illustrated in FIG. 5B, the insole 40a is configured with a lower height in the vicinity of the heel than the insole 40b illustrated in FIG. 5C. The insole 40a can easily apply pressure to the heel support portion 20 by suppressing the height in the vicinity of the heel. Therefore, the wearer can experience moderate sinking in the vicinity of the heel by laying the insole 40a on the shoe 1. In addition, since the wearer will experience a relatively deep subsidence near the heel, it will use greater muscle strength to move weight from the heel side to the toe side than during normal walking. A moderate load can be applied to a person's leg.
Next, as illustrated in FIG. 5C, the insole 40b is configured to have a height in the vicinity of the collar higher than that of the insole 40a illustrated in FIG. The insole 40b reduces the pressure applied to the heel support 20 and limits its elasticity by increasing the height in the vicinity of the heel. The insole 40b can prevent moderate sinking in the vicinity of the heel by limiting the elasticity of the heel support 20. Therefore, the wearer can smoothly move the weight from the heel side to the toe side because the heel does not sink from the insole 40a by laying the insole 40b on the shoe 1. Therefore, the insole 40b can walk lightly without applying a load to the muscle strength of the wearer's foot, compared to the insole 40a.
The insole 40 can appropriately adjust the height in the vicinity of the heel according to the elasticity of the heel support 20.

FIG. 6 is a diagram illustrating a cross-sectional shape when the midsole 2 and the heel support 20 are combined.
6A is a combination diagram of the midsole 2 and the heel support portion 20, and FIG. 6B is an end surface of the BB cut portion when the midsole 2 and the heel support portion 20 are combined.
As illustrated in FIG. 6A, the heel support portion 20 has a mid portion so that the heel support portion upper surface portion 20c and the peripheral portion 20e are in contact with the midsole ridge portion 8c and the peripheral portion 8d of the midsole 2. It is attached to the sole 2. When the heel support portion 20 is combined with the midsole 2, the heel support portion front end portion 20a, the heel support portion rear end portion 20b, and the heel support portion lower surface portion 20d include the midsole arch portion 8b and the midsole rear end. It is formed to be smoothly continuous with the portion 4b. The heel support portion 20 forms the heel support portion lower surface portion 20d so as to be smoothly continuous, thereby reducing an impact at the time of weight transfer from the wearer's heel side to the arch.
As illustrated in FIG. 6B, the heel support portion 20 projects the heel support portion upper surface portion 20 c in a convex shape with respect to the midsole 2. The midsole 2 is recessed in a concave shape with respect to the heel support portion 20. In the vicinity of the heel of the shoe 1, the heel support portion 20 and the midsole 2 are combined.
The heel support portion 20 is formed such that the heel support portion upper surface portion 20c protrudes not only in the direction from the heel support portion front end portion 20a to the heel support portion rear end portion 20b but also in the width direction and the midsole 2. Yes. Therefore, the wearer can experience more elasticity in the central region between the heel support portion upper surface portion 20c and the midsole heel portion 6c.
Further, the midsole 2 and the heel support portion 20 are assembled with the peripheral edge portion 8d and the peripheral edge portion 20e being in contact with each other. Therefore, the midsole 2 and the heel support portion 20 have a structure that is difficult to separate because the peripheral portion 8d and the peripheral portion 20e are combined with each other even when pressure from various directions is applied by the wearer.
