Description

The present invention relates to an insole that can stably transmit the force of the toes to the sole of the shoe, and shoes equipped with the insole.

As an insole for stably transmitting the force of the toes to the sole, an insole that includes an insole body and a toe bridge that is detachably attached to the insole body has been proposed (for example, Patent Document (see 1). This toe bridge includes a sole base part, an instep cover part, and a toe bridge part that connects the sole base part and instep cover part, and also has a slit in the front end of the insole body. The toe bridge portion of the toe bridge is inserted into the slit portion of the insole body.

In this insole, the toe bridge part of the toe bridge is located between the first toe and the second toe, and the toe bridge part is sandwiched between the first toe and the second toe. Therefore, the instantaneous force of the toe can be transmitted to the bottom of the toe of the shoe without loss, and athletic performance can be improved.

Patent No. 5806427

However, in conventional insoles, the toe bridge is removably inserted into the slit of the insole body, so if a large force is applied to the toe bridge when driving downhill or on a bumpy road, The toe bridge tends to move relative to the insole body, and the force of the toe cannot be reliably transmitted to the toe bottom of the shoe via the toe bridge and the insole body. In particular, when the insole is housed in the inner sole of the shoe, the sole base of the toe bridge is held in contact with the inner sole of the shoe, and the instep cover is held in contact with the inner surface of the upper of the shoe. Therefore, there is a problem in that it is difficult to hold the toe bridge sufficiently securely.

In addition, in this toe bridge, the toe bridge part is located between the first toe and the second toe, but since this toe bridge part is provided in a wall shape, the first toe and There is a problem in that it is difficult to grasp the toe bridge portion with the second toe, and therefore it is difficult to apply force to the toe tips including the first toe.

An object of the present invention is to provide an insole that can stably transmit the force of the tips of the toes to the sole of the shoe and that can strengthen the muscles of the toes, and shoes equipped with the insole.

The insole of the present invention includes an insole main body that can be stored in the inner sole of a shoe, a front tsubo provided at the front part of the insole main body on the toe side, and an end of the front tsubo provided on the side opposite to the insole main body. The instep side support member has a length from the center of the part in contact with the front tsubo to the tip on the toe side, and a length from the center of the part in contact with the front tsubo to the heel side end . It is characterized by being longer than its length.

In such an insole , it is preferable to provide a retention reinforcing part on the outer surface of the instep side support member to strengthen the retention on the instep part of the shoe.By configuring it in this way, the instep side support member and the shoe are The contact with the upper part of the foot is strengthened, and the positional relationship between the insole and the shoe does not shift even when you walk, run, climb, etc. wearing shoes containing an insole, and as a result, the position of the insole and the shoe does not shift. The position of the front tsubo sandwiched between the front and second toes does not shift.

In addition, in a state where the front tsubo stands upright with respect to the insole main body, it is preferable that the toe side tip of the instep side support member substantially overlaps the toe side tip of the insole main body at a distance in the upright direction of the front tsubo, With this configuration, when housed in the inner sole of the shoe, the tip of the instep support member reliably comes into contact with the inner surface of the tip of the shoe. movement toward the distal end side can be more reliably suppressed, and the front tsubo can be reliably held at a predetermined position between the insole main body and the instep support member.

In addition, when the instep support member is housed in the inner sole of the shoe, the toe side tip of the instep side support member contacts the inner surface of the toe side tip of the shoe, and the outer surface of the retention reinforcement portion provided on the instep side support member is in contact with the inner surface of the toe side tip of the shoe. It is preferable to configure it so that it comes into contact with the upper part of the shoe. By configuring it in this way, the tip of the instep side support member comes into contact with the inner surface of the tip of the shoe, and the outer surface of the retention reinforcement part comes into contact with the inner surface of the tip of the shoe. It is held in contact with the inner surface of the vamp, thereby making it possible to more reliably suppress movement of the instep support member toward the distal end of the shoe.

In addition, the front area is made up of a flexible hollow sleeve disposed between the insole body and the instep support member, and a core cable inserted through the hollow sleeve, and one end of the core cable is attached to the insole body. The other end may be fixed to the support member on the instep side. With this configuration, the first and second toes of the foot and the crotch of the toes between them are provided with flexibility. The hollow sleeve comes into contact and can provide a foot-friendly insole.

In addition, the front area is made up of a columnar member disposed between the insole body and the instep support member and an elastic sleeve covering this columnar member, one end of the columnar member is fixed to the insole body, and the other end is fixed to the insole body. may be fixed to the support member on the instep side. By configuring in this way, the first toe and the second toe of the foot can be secured while ensuring sufficient rigidity and strength by the columnar member at the center of the front tsubo. The elastic sleeve comes into contact with the toes and the crotch of the toes, and even with this configuration, it is possible to provide an insole that is gentle on the feet but highly irritating to the crotch of the toes.

Further, the front tsubo and the instep support member may be constructed integrally, and by constructing them in this way, they can be formed by integral molding of synthetic resin or the like, which improves the workability of manufacturing this insole. can be improved.

Further, it is preferable to provide a holding reinforcing part on the outer surface of the instep side support member to strengthen the hold on the instep part of the shoe.By configuring it in this way, the instep side support member of the insole and the instep part Even if you walk, run, or climb a mountain while wearing shoes containing this insole, the positional relationship between the insole and the shoe will not shift, and therefore the first toe and second toe of the foot will remain in contact with each other. The position of the front tsubo sandwiched between the two will not shift.

In addition, an insertion slit is provided in the front part of the insole body on the toe side in the direction connecting the toe side and the heel side, and the front part is inserted into the insertion slit so that the position can be adjusted freely, and then it is fixed to the insole body. By configuring it in this way, the front tsubo can be attached to the insertion slit in a position-adjustable manner, and the position of the front tsubo can be adjusted according to the depth of the crotch between the first toe and the second toe. It can be attached to the insole body. In short, if you adjust the length from the heel to the first and second toes to suit your individual feet, the length from the heel to the tip of the shoe will be slightly longer. Since they can firmly hold your feet, you can choose shoes with an emphasis on shape, even if they are slightly wider or larger.

By adjusting the position of the front tsubo so that when the shoes are worn, the toes do not come into contact with the inner surface of the toe-side tip of the shoe, stress is not applied to the toes, and the tips of the toes are Avoid damage and fatigue. This also improves the muscle strength of the toes.

In addition, it is preferable to provide an anti-slip member on the back surface of at least the front part on the toe side of the insole body to prevent slipping.With this configuration, the force of the toes is transferred to the sole of the shoe through the insole body. This allows for more stable walking, running, etc.

In addition, a thin part that reduces the thickness of the insole body may be provided in the area including the part that supports the toes in the front part of the insole body on the toe side. When climbing, the part where your toes touch the insole is thinner, making it easier for your toes to press down on the insole, which reduces the burden on the heel side and prevents lower back and knee pain. You can improve the strength of your toes.

Further, an adjustment part for adjusting the opening angle of the big toe may be provided on the tip of the toe side from the position where the front tsubo is provided. With this configuration, it is possible to push the body from the left and right. Even when you are attacked, your big toes and soles of your feet will be able to hold back. Moreover, by adjusting the position of this adjustment part, bunions can be corrected for each person.

Furthermore, the shoe of the present invention is characterized in that the insole according to any one of claims 1 to 11 is accommodated in the inner sole of the shoe body.

In such shoes, it is preferable to adjust the position of the front area so that the toes do not come into contact with the inner surface of the toe-side tip of the shoe when the shoe is worn. When wearing shoes, the tips of the toes do not come into contact with the inner surface of the tip of the toe side of the shoe, and stress and pressure are not applied to the tip of the toe, thereby avoiding damage and fatigue to the tip of the toe. This also improves the muscle strength of the toes.

Further, the retention reinforcing portion may be composed of a male hook-and-loop fastener or a female hook-and-loop fastener, and a corresponding female hook-and-loop fastener or male hook-and-loop fastener may be provided on the inner surface of the upper part of the shoe. By doing so, the movement of the support member on the instep side of the insole is reliably suppressed, and on the lower end side of the front tsubo, the insole main body is accommodated within the shoe main body, and the foot rests on this accommodated insole main body and weight is applied. As a result, the movement of the lower end side is reliably suppressed, and at the upper end side, the tip of the instep support member comes into contact with the inner surface of the tip of the shoe body, and the male surface of the instep support member side By attaching the fastener (or female hook-and-loop fastener) to the corresponding female hook-and-loop fastener (or male hook-and-loop fastener) on the inner surface of the upper part of the shoe body in a detachable manner, this movement of the upper end side is prevented. This is reliably suppressed, and as a result, the front tsubo can be reliably held at a predetermined location within the shoe body.

According to the insole of the present invention, the length of the instep side support member from the center of the part in contact with the front tsubo to the tip on the toe side is longer than the length from the center of the part in contact with the front tsubo to the heel side end. Therefore, when housed in the inner sole of the shoe, the instep side support member easily comes into contact with the inner surface of the tip of the shoe, preventing the instep side support member from moving toward the tip of the shoe, and the front area of the insole Since it is reliably supported between the foot and the instep support member, the crotch of the toes is reliably held on the front tsubo.

In other words, when you wear shoes with the insole stored in the inner sole of the shoe, the front tsubo is located between the first toe and the second toe, and when you walk, this front tsubo is located between the toes. As a result, when walking, the weight shifts in a straight line from the heel to the first toe, and as a result, the force of the toes is stably transmitted to the sole of the shoe, allowing walking, running, etc. It can be stabilized. In addition, in this walking and running state, the front foot acts on the crotch between the first and second toes, and when applying force to the toes, the first and second toes grasp the front foot . As a result, force is applied to the tips of the toes, making it easier to push forward, which also makes walking and running more stable.It also helps to improve the muscle strength of the toes, which is good for the toes. Excellent insoles and shoes can be provided.

Furthermore, according to the shoes of the present invention, any of the above-mentioned insoles is accommodated in the inner sole of the shoe body, so that the force of the toes can be stably transmitted to the sole, and the toes can be You can improve your muscle strength.

EMBODIMENT OF THE INVENTION Hereinafter, various embodiments of an insole according to the present invention and shoes equipped with the same will be described with reference to the accompanying drawings. First, a first embodiment of an insole according to the present invention will be described with reference to FIGS. 1 to 6.

1 to 5, the illustrated insole 2 includes an insole main body 4 corresponding to the shape of the inner surface of the sole 104 of the shoe 102 (i.e., the inner sole 106) (see FIG. 7), and the toe of the insole main body 4 The front side portion 6 is formed flat, and the center portion 10 in the width direction at the rear heel side 8 is formed flat, and both side portions 12 in the width direction curve upwardly. It extends upwards towards the direction. Therefore, in this insole main body 4, the back surface of the foot 108 is located on the flat part of the insole main body 4 (that is, the widthwise central part 10 of the toe side front part 6 and the heel side rear part 8), and The width direction side parts 12 wrap the heel side of the foot 108 from both sides, so that it can be accommodated in the shoe 102 and has a shape that corresponds to the foot.

Such an insole main body 4 can be formed from, for example, a flexible synthetic resin material, and its surface may be covered with a woven fabric or the like. Furthermore, the insole main body 4 may be made of a material that is substantially flat as a whole.

In this insole 2, a front area 14 is provided at the toe side front part 6 of the insole body 4, and an instep side support member 16 is provided at the upper end of this front area 14. The length of the front tsubo 14 is arbitrary, but it is desirable that the insole be at a height that does not put pressure on the toes when the insole is put in the shoe and can come into contact with the inner surface of the upper part 112 of the shoe. .

Referring also to FIG. 6, the front base 14 includes a cylindrical hollow sleeve as a flexible hollow sleeve and a pair of core cords 20 and 22 inserted through the cylindrical hollow sleeve 18. The hollow sleeve 18 can be made of, for example, a synthetic resin material, and the pair of core cords 20 and 22 can be made of, for example, a string of cloth. Note that the pair of core cables 20 and 22 may be combined into one, or the cylindrical sleeve 18 may be omitted.

In this first embodiment, one end (lower end, that is, the end on the insole main body 4 side) of the cylindrical hollow sleeve 18 is arranged so as to come into contact with the surface of the toe-side front part 6 of the insole main body 4, The other end (the upper end, that is, the end on the instep side support member 16 side) is arranged so as to abut the inner surface of the instep side support member 16, and connects one end side of the pair of core cords 20, 22 to one end of the hollow sleeve 10. They are supported between the insole main body 4 and the instep support member 16 by fixing them to the insole main body 4 through the sides and fixing their other ends to the instep support member 16 through the other end of the hollow sleeve 10. Ru.

In this first embodiment, one end side of the pair of core cords 20, 22 is made to protrude to the back side through the insertion slit 24 formed in the insole main body 4, for example, as shown by the broken line in FIG. It is fixed to the insole main body 4 by expanding one end and fixing it to the outer surface of the insole main body 4 with an adhesive or the like. Although not shown, the other ends of the pair of core ropes 20 and 22 may be expanded, for example, and fixed to the inner surface of the instep support member 16 with adhesive or the like. It is fixed to the side support member 16. This insertion slit 24 extends in a direction connecting the toe side and heel side of the insole main body 4, and therefore, the position of the front area 14 can be adjusted in this direction.

In this first embodiment, the pair of core cords 20, 22 are attached through the insertion slit 24 of the insole main body 4, so before the pair of core cords 20, 22 are fixed, these core cords 20, 22, 22 can be moved in the front-rear direction of the insole body 4 (horizontal direction in FIG. 7) along the insertion slit 24, and by moving in this way, the attachment position of the front tsubo 14 to the insole body 4 can be adjusted. Can be done.

For example, when going down stairs or down a mountain path, the tips of the toes are usually pressed against the inner surface of the tip of the toe side of the shoe and may be stressed. This can lead to damage to the toes and fatigue throughout the body. Therefore, when the shoe is worn, the position of the front tsubo 14 can be set using the insertion slit 24 at a position where the toe does not come into contact with the inner surface of the toe-side tip of the shoe.

In addition, in this form, one end (lower end) of the cylindrical hollow sleeve 18 of the front tsubo 14 is brought into contact with the surface of the insole main body 4, but instead of such a configuration, the front of the insole main body 4 on the toe side An insertion opening is provided in the section 6 (in this case, the slit 24 is omitted), and one end of the cylindrical hollow sleeve 18 is positioned within this insertion opening and fixed with adhesive or the like, and the hollow sleeve inside this insertion opening is One end side of the pair of core cords 20, 22 may be made to protrude to the back side of the insole main body 4 through one end side of the insole body 4 and fixed as described above.

Further, in the first embodiment, the other end (upper end) of the cylindrical hollow sleeve 18 of the front tsubo 14 is brought into contact with the inner surface of the back support member 16, but instead of such a configuration, the front Similar to the lower end side of the tsubo 14, an insertion opening is provided in the instep side support member 16, and the other end of the cylindrical hollow sleeve 18 is positioned within this insertion opening and fixed with adhesive, etc. The other end side of the pair of core cords 20, 22 may be made to protrude to the outer surface side of the instep support member 16 through the other end side of the hollow sleeve 18, and fixed as described above.

Although the hollow sleeve 18 has a cylindrical shape in the first embodiment, it is not necessarily limited to this, and can be modified as appropriate. For example, the hollow sleeve 18 may be shaped like a triangular prism, a hexagonal prism, an elliptical cylinder, etc. Even with such a configuration, the hollow sleeve 18 can be firmly held at the crotch of the toe.

In addition, the instep side support member 16 can be made of, for example, a synthetic resin material, and its width W (see FIG. 3) is configured to be larger than the widths of the first and second toes of the foot. With this configuration, the front floor 14 can be supported reliably.

In addition, as shown in FIGS. 2 and 3, the instep side support member 16 has a substantially flat plate shape, and the length SL from the center of the part in contact with the front tsubo 14 to the tip on the toe side is equal to the front tsubo 14. It is configured to be longer than the length KL from the center of the contacting part to the heel side end. Therefore, the toe-side tip of the instep side support member 16 extends in the direction of the toe-side tip of the insole main body 4, and is configured not to extend too long toward the heel. It should be noted that the heel side portion of the instep support member 16 may be constructed so as to hardly protrude from the front tsubo 14 toward the heel side. In this case, the length from the center of the part in contact with the front tsubo 14 to the heel side end is approximately equal to the radius of the front area 14.

With this configuration, when housed in the inner sole 106 of the shoe 102, the tip of the instep support member 16 easily comes into contact with the inner surface of the tip 110 of the shoe 102, as shown in FIG. The movement of the instep support member 16 toward the distal end of the shoe 102 can be reliably suppressed, and the instep support member 16 does not extend too long toward the heel, so that it does not impede insertion of the foot. There is. It is desirable that this instep support member 16 has a certain degree of rigidity, so that the tip of the instep support member 16 does not come into contact with the inner surface of the tip of the shoe and undergo large elastic deformation, and as a result, the front It is possible to prevent the tsubo 14 from moving forward.

This insole 2 is preferably configured such that when the front tsubo 14 is in an upright state, the tip of the instep support member 16 substantially overlaps the tip of the insole main body 4 with an interval in the upright direction of the front tsubo. Thereby, the tip of the instep support member 16 can be reliably brought into contact with the inner surface of the tip 110 of the shoe 102.

In this stowed state, the outer surface of the instep support member 16 contacts the instep part 112 of the shoe 102, and this contact causes friction with the instep part 112, and the suppression of deformation of the instep support member 16 causes It is possible to prevent the side support member 16 from moving toward the distal end of the shoe 102, and as a result, the front base 14 is moved between the insole main body 4 and the instep side support member 16, that is, at a predetermined part of the front inside the shoe 102. can be held securely.

In this first embodiment, an anti-slip member 32 is disposed on the back surface of the toe-side front portion 6 of the insole main body 4. The surface of this anti-slip member 32 is provided with an appropriate anti-slip shape. The anti-slip member 32 is made of a material such as rubber or synthetic rubber, and is fixed to the insole main body 4 using, for example, an adhesive. By providing the anti-slip member 32, the force from the toe is reliably transmitted to the inner sole 106 of the shoe 102 via the insole main body 4 and the anti-slip member 32, making it possible to stabilize walking and running. Furthermore, with this configuration, one end of the pair of core cords 20, 22 (the end exposed on the back surface of the insole main body 4) is covered by the anti-slip member 32, and one end of these core cords 20, 22 is covered with the anti-slip member 32. can be fixed more reliably, and the front bottom surface of the insole 2 can be made flat. The desired effect can be achieved by providing the anti-slip member 32 on the back surface of at least the toe-side front portion 6 of the insole main body 4, but it may also be provided on the back surface of the entire insole main body.

Furthermore, in this first embodiment, a pair of cover members 34 are provided on the inner surface of the instep support member 16 (see FIGS. 2, 5, and 6). This cover member 34 is formed of, for example, woven fabric, non-woven fabric, leather, rubber, synthetic resin, etc., and as understood from the above description, the other end of the pair of core cords 20, 22 (the back support member 16 The other end portions of these core cables 20, 22 can be fixed more reliably.

As shown in FIG. 7, the insole 2 is housed in a shoe 102, such as a walking shoe, an athletic shoe, or a sports shoe, and is placed on the surface of an inner sole 106 of the shoe. In this stored state, as shown in FIG. 7, the tip of the insole main body 4 contacts the inner surface of the lower end of the tip 110 of the shoe 102, and the tip of the instep support member 16 contacts the inner surface of the lower end of the tip 110 of the shoe 102. It comes into contact with the inner surface of the upper end portion, thereby reliably suppressing the movement of the insole main body 4 and the instep support member 16, in other words, the front area 14 toward the distal end side of the shoe 102. It can be held securely in the front part. Furthermore, on the lower end side of the front tsubo 14, when the shoe 102 is worn, the foot 108 rests on the insole main body 4, so the weight acts on the insole main body 4 via the foot 108, and this also causes the front Movement of the lower end side of the tsubo 14 is suppressed.

In order to more reliably suppress the movement of the upper end side of the front tsubo 14, although not shown, it is possible to provide a holding reinforcement part on the outer surface of the instep support member to strengthen the holding of the shoe 102 to the instep part. can. The holding reinforcing portion can be configured, for example, from a hook-and-loop fastener (male hook-and-loop fastener or female hook-and-loop fastener) provided at least on the outer surface of the instep support member 16, and by providing the hook-and-loop fastener in this way, The movement of the instep support member 16 on the side of the insole 2 can be more reliably suppressed, and the front tsubo 14 can always be kept upright, making it easier to wear the shoe 102 containing the insole 2. The quality is improved.

In addition, for example, a female hook-and-loop fastener (or male hook-and-loop fastener) that is removably attached to, for example, a male hook-and-loop fastener (or female hook-and-loop fastener) provided on the outer surface of the instep support member 16 of the insole 2 is attached to the shoe 102 body. It may be provided on the inner surface of the vamp 112 side. Thereby, the front seat 14 can be held in a predetermined position within the shoe 102 body more reliably. These male hook-and-loop fasteners (or female hook-and-loop fasteners) can be attached to the outer surface of the instep support member 16 with an adhesive or sewn with thread (or string).

Although the instep support member 16 may be detachably attached to the inner surface of the upper part 112 of the shoe 102 using a hook-and-loop fastener as described above, instead of configuring it in this way, The support member 16 may be fixed to the inner surface of the upper part 112 of the shoe 102 with an adhesive or the like, or may be sewn onto the upper part 112 with thread or the like.

The shoe 102 containing the insole 4 is worn so that the front tsubo 14 is located within the crotch of the toe between the first toe and the second toe of the foot 108. When walking (running) wearing these shoes 102, the front foot 14 acts on the crotch between the first toe and the second toe, and as a result, the weight shift when walking is in a straight line from the heel to the first toe. As a result, the force of the toes is transferred to the sole of the shoe, allowing for stable walking (running). In addition, in this walking (running) state, the foretsubo 14 acts on the crotch between the first toe and the second toe, so when kicking the ground, the pressure is applied to the toe tip. This also makes it possible to stabilize walking (running), and to strengthen the muscle strength of the toes and soles so that the foot can maintain its hold when kicking. As a result, walking posture can be improved and lower back pain, knee pain, etc. can be prevented. In addition, since the outer shape of the front tsubo 14 is cylindrical, it is easier to grasp by the first toe and second toe, which makes it easier to apply force to the toes of the foot and hold down when kicking, increasing the muscle strength of the toes and the sole of the foot. can be achieved.

For example, the front tsubo may be configured as shown in FIG. In FIG. 8 showing a modified front floor, the front floor 14A is composed of a columnar member 52 and, for example, a cylindrical elastic sleeve 54 as an elastic sleeve that covers the columnar member 52. A shaped elastic sleeve 54 is disposed between the insole main body 4A and the instep support member 16A.

In this modified form, a lower female threaded hole 56 is provided at one end of the columnar member 52, and by screwing the male threaded portion 60 of the mounting screw 58 into this lower female threaded hole 56 through the insole main body 4A, A lower end portion of the columnar member 52 is fixed to the insole main body 4A. Further, an upper female threaded hole 62 is provided on the other end side of this columnar member 52, and by screwing the male threaded portion 66 of the mounting screw 64 into this upper female threaded hole 62 through the instep support member 16A, The upper end of the columnar member 52 is fixed to the instep support member 16A.

In such a front floor 14A, the columnar member 52 can be formed from a metal material such as iron or stainless steel, or a hard synthetic resin material, and by forming from such a material, the columnar member 52 has rigidity. and strength. In addition, the elastic sleeve 54 can be formed from a soft synthetic resin material, a foamed resin material, etc. By configuring it in this way, it is gentle on the foot but does not affect the crotch of the toe between the first and second toes. A highly stimulating insole can be provided.

In addition, as a front tsubo of another modified form, the mounting screw 58 (or the mounting screw 64) is lengthened, and the columnar member 52 and the instep support member 16A ( or the columnar member 52 and the insole main body 4A ) are A nut (not shown ) may be screwed onto the male threaded portion 60 (or 66) protruding from the instep support member 16A (or the insole main body 4A) to fix it. Screw 64 (or 58) is omitted. Thereby, the configuration can be simplified and the ease of assembly can be improved. Instead of such a configuration, the columnar member 52 is omitted, the male threaded portion 60 (or 66 ) of the mounting screw 58 (or 64) is inserted through the inside of the elastic sleeve 54, and the instep side support member 16 (or insole main body 4A) is inserted. Alternatively, a nut may be screwed onto the male threaded portion 60 (or 66) protruding from the housing .

In a further modified form of the front tsubo, the front tsubo 14A and the instep support member 16A may be integrally formed of synthetic resin or the like. In that case, the lower end side of the front tsubo 14A may be fixed to the insole main body 4.

Next, a second embodiment of the insole according to the present invention will be described with reference to FIGS. 9 to 11. This second embodiment is different from the first embodiment in that a thinner part is provided in the area including the part that supports the toes in the front part of the insole body on the toe side. It is different from

In FIG. 9, in the insole 202 of the second embodiment, a thinner part 261 is formed by reducing the thickness of the insole main body 204 in a region including the part that supports the toes in the toe-side front part 206 of the insole main body 204. The thin portion 261 is provided in an inverted V shape at the front portion on the toe side. In the second embodiment, as shown in FIG. 10, a thin portion 261A is formed by removing a thickness D from the surface of the insole main body 204 on the front side that comes in contact with the foot. Note that the structure is not limited to the above-mentioned structure, and as shown in FIG. 11, the thin wall portion 261B is formed by removing the thickness D by scraping the back side of the insole body 204 that is in contact with the foot and the opposite side that is in contact with the shoe. Alternatively, both the front and back surfaces of the insole main body 204 may be removed by a desired thickness to form a thin portion. Although the cutting thickness D for forming the thin portion 261A (261B) is arbitrary, it is desirable that the degree of freedom of the toes can be ensured as much as possible and that the toes can be stepped on.

In the second embodiment, the thin portions 261 (261A, 261B) are formed in an inverted V shape, but the shape is not necessarily limited to this and may be modified as appropriate. For example, the thin wall portion may be formed only in the portion that contacts each finger, or the thin wall portion may be formed in a region that includes the ball of the foot in addition to the portion that contacts each finger. It is sufficient that the thin portion exists in a region including at least a portion where each finger including the thumb comes into contact with the insole main body 204.

In this way, in the second embodiment, the thin wall portion 261 (261A, 261B) that reduces the thickness of the insole main body is provided in the area including the part that supports the toes in the front part of the insole main body 204 on the toe side. As a result, when climbing a mountain path or stairs, the part where the toes come into contact with the insole body 204 becomes thinner, making it easier for the toes to press on, reducing the burden on the heel side, and preventing lower back pain and knee pain. . In addition, since the degree of freedom of the toes is improved, it is expected that the strength of the toes will be improved.

Next, a third embodiment of the insole according to the present invention will be described with reference to FIGS. 12 and 13. This third embodiment differs from the above-described first and second embodiments in that an adjustment section for adjusting the opening angle of the thumb is provided.

12 and 13, in the insole 302 of this third embodiment, an adjustment part 319 for adjusting the opening angle of the thumb is provided in addition to the front area 14, and this adjustment part 319 is connected to the insole main body 304. It is provided closer to the tip of the toe than the position where the front tsubo 314 is provided.

This adjustment part 319 has the same material and shape as the front tsubo 314, and its lower end is fixed to the insole main body 304, and its upper end is fixed to the instep support member 316. Regarding the positional relationship from the front tsubo 314, the adjustment part 319 is provided a distance A away from the front tsubo 314 toward the tip of the toe, and this distance A is arbitrary depending on the size of each person's big toe. In this third embodiment, this distance A is, for example, 25 mm. This distance A may be configured to be adjustable depending on the size and shape of each person's toes. This distance A can be adjusted by inserting one end of the adjusting section 319 through a slit provided in the insole main body 304 and inserting the other end through a slit provided in the instep side restraining member.

By providing this adjustment portion 319, it is possible to adjust the angle at which the thumb opens outward (to the side opposite to the index finger). For example, by adjusting the front and rear positions using slits to create the optimal angle for each person, force is applied to the big toe and sole of the foot even when the body is pushed from the left and right. You can hold out. Furthermore, by adjusting the position in the left and right directions, it is possible to correct bunions for each person.

In the third embodiment, the adjustment part 319 is provided at a position closer to the tip of the toe than the position where the front tsubo 314 is provided. The adjustment portion 319 may be provided by adjusting its installation position to a position closer to the thumb. In this case, the position can be adjusted by providing a new slit diagonally from the front tsubo 314 toward the thumb and inserting the adjustment part 319 through the new slit . By increasing the opening angle between the thumb (first toe) and index finger (second toe), bunion can be further corrected.

In this third embodiment, the adjustment portion 319 may have the same material and shape as the front tsubo 14. For example, it may be configured to include a hollow sleeve 18 as a hollow sleeve having flexibility in the front area 14 described above, and a pair of core cords 20 and 22 inserted through this hollow sleeve 18. The hollow sleeve 18 may be omitted and only the pair of core cables 20 and 22 may be provided. Further, the adjustment portion 319 may be configured as the above-mentioned columnar member 52 and the cylindrical elastic sleeve 54 as an elastic sleeve that covers the columnar member 52. At that time, the configuration of the front floor 14 and the configuration of the adjustment section 319 may be different. Furthermore, the instep side support member 316, the front tsubo 14, and the adjustment part 319 may be formed integrally.

In this way, in the third embodiment, since the adjustment part for adjusting the opening angle of the big toe is provided on the tip of the toe side from the position where the front tsubo is provided, it is possible to adjust the opening angle of the big toe. At times, the pressure is applied to the big toe and the sole of the foot, making it possible to press down. Furthermore, by adjusting the position, it is possible to correct bunions for each person.

Although various embodiments of the insole and shoes equipped with the insole according to the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes can be made without departing from the scope of the present invention. is possible.

For example, in the above-described embodiment, the insole body is configured to correspond to the shape of the entire inner sole of the shoe and accommodated so as to cover the entire inner sole, but the insole body is not limited to such a configuration, The insole body may correspond to the shape of the front part of the inner sole of the shoe and be accommodated so as to cover the front area of the inner sole of the shoe.
