Description

  The present invention relates to an insole capable of stably transmitting a force of a toe to a shoe sole and a shoe including the insole.

  As an insole for stably transmitting the force of a toe to a shoe sole, an insole body and a toe bridge which is detachably attached to the insole body have been proposed (for example, Patent Document 1). 1). This toe bridge comprises a sole base, an instep cover, a toe bridge connecting the sole base and the instep cover, and a slit at the front end of the insole body. The toe bridge part of the toe bridge is inserted into the slit part of the insole body.

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

Japanese Patent No. 5806427

  However, in the conventional insole, since the toe bridge is configured to be removably inserted into the slit portion of the insole body, when a large force is applied to the toe bridge when traveling on a downhill or a bumpy road, The toe bridge easily moves 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, in a state where the insole is accommodated 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 its upper cover is held in contact with the inner surface of the upper of the shoe. Therefore, there is a problem that it is difficult to hold the toe bridge sufficiently reliably.

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

  An object of the present invention is to provide an insole capable of stably transmitting the force of the toes to the sole of the shoe and improving the muscles of the toes, and a shoe provided with the insole.

  The insole according to the present invention is provided at an insole main body that can be accommodated in the inner sole of the shoe, a front tsubo provided at a toe-side front portion of the insole main body, and provided at an end of the front tsubo opposite to the insole main body. The back support member has a length from the center of the portion in contact with the front tsubo to the tip of the toe side, and the length from the center of the portion in contact with the front tsubo to the heel side end. It is longer than the length.

  In such an insole, it is preferable to provide a holding reinforcement portion on the outer surface of the upper support member to enhance the holding of the shoe on the upper portion. Even when walking, running, climbing, or the like while wearing shoes containing the insole, the positional relationship between the insole and the shoes does not shift, and the first toe of the foot is thereby improved. The position of the front tsubo sandwiched between the first and second toes does not shift.

  Further, in a state in which the front tsubo stands upright with respect to the insole body, it is preferable that the toe-side tip of the instep support member substantially overlaps with the toe-side tip of the insole body in the front tsubo upright direction, With this configuration, in a state in which the shoe is accommodated in the inner sole of the shoe, the tip of the upper support member surely comes into contact with the inner surface of the tip of the shoe. Can be more reliably suppressed from moving to the distal end side, and the front tsubo can be reliably held at a predetermined portion between the insole main body and the back support member.

  Further, in a state of being stored in the inner bottom of the shoe, the toe-side tip of the instep support member abuts against the inner surface of the toe-side tip of the shoe, and the outer surface of the holding reinforcement portion provided on the instep support member is It is preferable that the upper part of the shoe be in contact with the upper part of the shoe. With this configuration, the tip part of the upper support member abuts on the inner surface of the tip part of the shoe, and the outer surface of the holding reinforcing part is formed of the shoe. It is held in contact with the inner surface of the instep portion, whereby the movement of the instep support member toward the tip of the shoe can be suppressed more reliably.

  In addition, a flexible hollow sleeve disposed between the insole main body and the instep supporting member and a core cable inserted through the hollow sleeve constitute the front tsubo, and one end of the core cable is attached to the insole body. And the other end may be fixed to the instep support member. With such a configuration, the first and second toes of the foot and the toe between them are flexible. The hollow sleeve comes into contact, providing a foot-friendly insole.

  In addition, the front tsubo is composed of a columnar member disposed between the insole main body and the back support member and an elastic sleeve covering the columnar member, and one end of the columnar member is fixed to the insole main body, and the other end is fixed. May be fixed to the back support member. With such a configuration, the first toe and the second toe of the foot can be secured while securing 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 toes between them, and even with such a configuration, it is possible to provide an insole which is gentle to the feet but strongly stimulates the toes.

  In addition, the front tsubo and the back support member may be integrally formed. With such a configuration, for example, the front tsubo and the back support member can be formed by integral molding of a synthetic resin or the like. Can be improved.

  In addition, it is preferable to provide a holding reinforcement portion on the outer surface of the upper support member to enhance the holding of the shoe to the upper portion. With this configuration, the upper support member of the insole and the upper portion of the shoe are provided. The contact between the insole and the shoe is not shifted even when walking, running, climbing, or the like while wearing the shoe in which the insole is housed, so that the first and second toes of the foot are not displaced. The position of the front tsubo sandwiched between and does not shift.

  Also, an insertion slit may be provided in the toe side front part of the insole body in a direction connecting the toe side and the heel side, and the front tsubo may be fixed to the insole body after the front tsubo is inserted through the insertion slit so as to be freely adjustable. With such a configuration, the front tsubo can be attached to the insertion slit in a freely adjustable manner, and the position of the front tsubo can be adjusted according to the depth of the toe crotch between the first toe and the second toe. Can be attached to the insole body. In short, if the length from the heel of the foot to the toe of the first and second toes of the toe is adjusted according to the individual's foot, the length from the toe to the tip of the shoe is slightly longer. Because the foot can be held firmly, even a slightly wider and larger shoe can be selected with a focus on the shape.

  Then, when the shoe is worn, by adjusting the position of the front tsubo so that the toe does not come into contact with the inner surface of the toe side tip of the shoe, stress is not applied to the tip of the toe, and Damage and fatigue can be avoided. In addition, it is possible to improve the muscular strength of the toes.

  Further, it is preferable to provide a non-slip member for suppressing slippage on at least the back surface of the front part of the insole body on the toe side. With this configuration, the force of the toes of the toes can be applied to the sole of the shoe via the insole body. , And walking, running, and the like can be further stabilized.

  In addition, a thin portion for reducing the thickness of the insole body may be provided in a region including the portion supporting the toe in the toe side front portion of the insole body. When climbing, because the part where the toe is in contact with the insole body is thin, the toe is easy to step on, which reduces the burden on the heel side and can prevent back pain and knee pain, Strength of toes can be improved.

  In addition, an adjusting portion for adjusting the opening angle of the toe may be provided on the tip end side of the toe from the position where the front tsubo is provided. When you do, you can press on your toes and soles. Further, by adjusting the position of the adjusting section, the hallux valgus of each person can be corrected.

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

  In such shoes, it is preferable to adjust the position of the front tsubo so that the toes do not come into contact with the inner surface of the toe-side tip of the shoes when the shoes are worn. When wearing the toe, the tip of the toe does not come into contact with the inner surface of the tip of the toe of the shoe, so that stress is not applied to the tip of the toe and the toe is not pressed, so that damage and fatigue of the toe can be avoided. In addition, it is possible to improve the muscular strength of the toes.

  Further, the holding reinforcement portion may be constituted by a male hook-and-loop fastener or a female hook-and-loop fastener, and the 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 insole support member of the insole is reliably suppressed, and at the lower end side of the front tsubo, the insole body is housed in the shoe body, and the feet are put on the housed insole body and the weight is added. Thereby, the movement on the lower end side is reliably suppressed, and on the upper end side, the front end of the upper support member contacts the inner surface of the front end of the shoe body, and the male surface on the upper support member side. When the fastener (or female hook-and-loop fastener) is detachably attached to the corresponding female hook-and-loop fastener (or male hook-and-loop fastener) on the inner surface of the upper part of the upper part of the shoe body, the movement of the upper end side is prevented. Is reliably suppressed, and as a result, The basis may be held securely at a predetermined portion of the shoe body.

  According to the insole of the present invention, the instep support member has a length from the center of the portion in contact with the front tsubo to the tip end of the toe is longer than the length from the center of the portion in contact with the front tsubo to the heel side end. Therefore, the upper support member can easily come into contact with the inner surface of the tip of the shoe when housed in the inner sole of the shoe, and the upper support member can be prevented from moving toward the distal end of the shoe. The toe crotch is securely held on the front tsubos because it is securely supported between the upper back support member.

  In other words, when the shoe is worn while the insole is accommodated in the inner sole of the shoe, the anterior tsubo is located at the toe between the first toe and the second toe of the foot. Acts, and thereby, the weight shift when walking moves linearly from the heel toward the first toe, and as a result, the force of the toes is stably transmitted to the shoe sole, and walking, running, etc. Can be stabilized. In addition, in this walking and running state, the anterior tsubo acts on the toe crotch between the first toe and the second toe. As a result, force is applied to the tip of the toe and the toe becomes more powerful, which also makes walking, running, etc. stable, and also increases the muscle strength of the toe. Excellent insoles and shoes can be provided.

  Further, according to the shoe of the present invention, since any of the above-mentioned insoles is housed in the inner sole of the shoe main body, the force of the toe can be stably transmitted to the sole of the shoe, and the toe of the toe can be stably transmitted. Muscle strength can be improved.

The front view which shows some insoles of FIG.

  Hereinafter, various embodiments of an insole according to the present invention and a shoe including 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 5, the insole 2 shown includes an insole body 4 corresponding to the shape of the inner surface of the bottom 104 of the shoe 102 (that is, the inner sole 106) (see FIG. 7). The side front part 6 is formed flat, the center part 10 in the width direction of the rear part 8 on the heel side is formed flat, and both side parts 12 in the width direction are curved upward and extend. It extends obliquely upward toward the direction. Accordingly, in the insole body 4, the back surface of the foot 108 is located at a flat portion of the insole body 4 (ie, the width direction central portion 10 of the toe-side front portion 6 and the heel-side rear portion 8). The width-direction both sides 12 wrap the heel side of the foot 108 from both sides, so that the shoe 108 can be accommodated in the shoe 102 and has a shape corresponding to the foot.

  Such an insole main body 4 can be formed of, for example, a synthetic resin material having flexibility, and its surface may be covered with a woven cloth or the like. Further, as the insole main body 4, a generally flat one may be used.

  In the insole 2, a front tsubo 14 is provided at the toe-side front portion 6 of the insole main body 4, and an upper support member 16 is provided at an upper end of the front tsubo 14. The length of the front tsubo 14 is arbitrary, but it is preferable that the insole is accommodated in shoes and does not compress the toes, and has a height capable of abutting against the inner surface of the upper part 112 of the shoes. .

  Referring to FIG. 6 as well, the front tsubo 14 includes a cylindrical hollow sleeve as a hollow sleeve having flexibility, and a pair of core cords 20 and 22 provided through the cylindrical hollow sleeve 18. The hollow sleeve 18 can be formed of, for example, a synthetic resin material, and the pair of core cords 20, 22 can be, for example, a cord-shaped cloth. It should be noted that a pair of core cords 20 and 22 may be combined into one, or the cylindrical sleeve 18 may be omitted.

  In the first embodiment, one end (the lower end, that is, the end on the insole body 4 side) of the cylindrical hollow sleeve 18 is disposed so as to contact the surface of the toe side front part 6 of the insole body 4. The other end (upper end, that is, the end on the back support member 16 side) is disposed so as to contact the inner surface of the back support member 16, and one end of the pair of core cords 20 and 22 is connected to one end of the hollow sleeve 10. By fixing the other end side of the insole body 4 to the instep support member 16 through the other end side of the hollow sleeve 10, it is supported between the insole body 4 and the instep support member 16. You.

  In the first embodiment, one end side of the pair of core cords 20 and 22 is projected to the back side through an insertion slit 24 formed in the insole main body 4, for example, as shown by a broken line in FIG. One end is expanded and fixed to the outer surface of the insole main body 4 with an adhesive or the like, whereby the insole main body 4 is fixed. The other ends of the pair of core cords 20 and 22 are not shown, but, for example, the other ends are expanded and fixed to the inner surface of the upper support member 16 with an adhesive or the like. It is fixed to the side support member 16. The insertion slit 24 extends in a direction connecting the toe side and the heel side of the insole main body 4, so that the front tsubo 14 can be adjusted in this direction.

  In the first embodiment, since the pair of core cords 20 and 22 are attached through the insertion slits 24 of the insole main body 4, before the pair of core cords 20 and 22 are fixed, the core cords 20 and 22 are fixed. 22 can be moved in the front-rear direction (left-right direction in FIG. 7) of the insole main body 4 along the insertion slit 24, and by moving in this way, the mounting position of the front tsubos 14 with respect to the insole main body 4 can be adjusted. Can be.

  For example, when descending stairs or down a mountain path, the tip of the toe may be pressed against the inner surface of the toe-side tip of the shoe, which may cause stress. As a result, the toes may be damaged or the whole body may feel tired. 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 tip does not contact the inner surface of the tip end of the shoe.

  In this embodiment, 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. An insertion opening is provided in the portion 6 (in this case, the slit 24 is omitted). One end of the cylindrical hollow sleeve 18 is positioned in the insertion opening and fixed with an adhesive or the like. One end of the pair of core cords 20 and 22 may be made to protrude toward the back side of the insole main body 4 through one end of the cable 18 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 in contact with the inner surface of the back support member 16. Similarly to the lower end of the tsubo 14, an insertion opening is provided in the upper support member 16, and the other end of the cylindrical hollow sleeve 18 is positioned in the insertion opening and fixed with an adhesive or the like. The other end of the pair of core cords 20 and 22 may be projected to the outer surface of the back support member 16 through the other end of the hollow sleeve 18 and fixed as described above.

  In the first embodiment, the hollow sleeve 18 has a cylindrical shape. However, the present invention is not limited to this, and can be appropriately changed. For example, the shape may be a triangular prism, hexagonal column, elliptical column, or the like. Even with such a configuration, the hollow sleeve 18 can be firmly held on the toe.

  The back support member 16 can be formed 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 tsubo 14 can be reliably supported.

  As shown in FIGS. 2 and 3, the instep supporting member 16 has a substantially flat plate shape, and the length SL from the center of the portion in contact with the front tsubo 14 to the tip of the toe side is equal to that of 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 supporting member 16 is configured to extend in the direction of the toe-side tip of the insole main body 4 and not to extend too long to the heel side. Note that the heel side portion of the instep support member 16 may be configured to hardly protrude from the front tsubo 14 to the heel side. In this case, the length from the center of the portion in contact with the front tsubo 14 to the heel side end portion Is substantially equal to the radius of the front tsubo 14.

  With such a configuration, in a state in which the shoe is stored in the inner bottom 106 of the shoe 102, as shown in FIG. 7, the distal end of the upper support member 16 easily comes into contact with the inner surface of the distal end 110 of the shoe 102, The movement of the upper support member 16 to the tip side of the shoe 102 can be reliably suppressed, and the upper support member 16 does not extend too long on the heel side, so that the insertion of the foot is not prevented. I have. It is desirable that the upper support member 16 has a certain degree of rigidity, so that the front end of the upper support member 16 does not abut on the inner surface of the front end of the shoe and undergoes large elastic deformation. The movement of the tsubo 14 forward can be suppressed.

  In the insole 2, it is preferable that the front end of the instep supporting member 16 be substantially overlapped with the front end of the insole main body 4 at an interval in the front tread upright direction when the front insole 14 is upright. Thereby, the front end of the upper support member 16 can be reliably brought into contact with the inner surface of the front end 110 of the shoe 102.

  In this stored state, the outer surface of the upper support member 16 comes into contact with the upper 112 of the shoe 102, and the contact with the upper 112 causes friction between the upper and the upper 112, and deformation of the upper support 16 is suppressed. The movement of the side support member 16 to the tip side of the shoe 102 can be prevented. As a result, the front tsubo 14 is placed between the insole body 4 and the upper support member 16, that is, a predetermined portion of the front portion in the shoe 102. Can be securely held.

  In the first embodiment, a non-slip member 32 is provided on the back surface of the toe-side front portion 6 of the insole main body 4. The surface of the anti-slip member 32 has an appropriate anti-slip shape. The non-slip member 32 is formed of, for example, a material such as rubber or synthetic rubber, and is fixed to the insole main body 4 by, for example, an adhesive. By providing the non-slip member 32, the force from the toe is transmitted to the inner sole 106 of the shoe 102 via the insole main body 4 and the non-slip member 32, so that walking and running can be stabilized. Further, with this configuration, one end of the pair of core cords 20 and 22 (ends exposed on the back surface of the insole main body 4) is covered with the non-slip member 32, and one end of the core cords 20 and 22 is provided. Can be fixed more reliably, and the front bottom surface of the insole 2 can be flattened. Although the desired effect can be achieved by providing the non-slip member 32 on at least the back surface of the toe-side front portion 6 of the insole body 4, it may be provided on the entire back surface of the insole body.

  Furthermore, in the first embodiment, a pair of cover members 34 are provided on the inner surface of the back support member 16 (see FIGS. 2, 5 and 6). The cover member 34 is formed of, for example, woven fabric, nonwoven fabric, leather, rubber, synthetic resin, or the like, and as understood from the above description, the other ends of the pair of core cords 20 and 22 (the back support member 16). Of the core wires 20 and 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, and a sports shoe, and is placed on a surface of an inner bottom 106 thereof. In this stored state, as shown in FIG. 7, the tip of the insole main body 4 abuts on the inner surface of the lower end portion of the tip 110 of the shoe 102, and the tip of the upper support member 16 is the tip of the tip 110 of the shoe 102. It comes into contact with the inner surface of the upper end portion, so that the movement of the insole body 4 and the back support member 16, in other words, the front tsubo 14 toward the tip side of the shoe 102 is reliably suppressed. Can be securely held at the front part. In addition, on the lower end side of the front tsubo 14, when the shoes 102 are worn, the foot 108 rests on the insole body 4, so that the weight acts on the insole body 4 via the foot 108, whereby The movement of the lower end 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 necessary to provide a holding reinforcing portion on the outer surface of the upper support member for strengthening the holding of the shoe 102 to the upper part. it can. As the holding reinforcing portion, for example, a hook-and-loop fastener (a male hook-and-loop fastener or a female hook-and-loop fastener) provided on at least the outer surface of the back support member 16 can be used. By providing such a hook-and-loop fastener, The movement of the back support member 16 on the insole 2 can be more reliably suppressed, and the front tsubo 14 can be kept upright at all times. As a result, the shoes 102 containing the insole 2 can be easily worn. Is improved.

  Further, for example, a female hook-and-loop fastener (or male hook-and-loop fastener) detachably attached to, for example, a male hook-and-loop fastener (or a female hook-and-loop fastener) provided on the outer surface of the instep side supporting member 16 of the insole 2 is attached to the shoe 102. May be provided on the inner surface of the instep portion 112 side. Thereby, the front tsubo 14 can be more reliably held at a predetermined portion in the main body of the shoe 102. These male hook-and-loop fasteners (or female hook-and-loop fasteners) can be attached to the outer surface of the back support member 16 with an adhesive or sewn with a thread (or string).

  As described above, the upper support member 16 may be detachably attached to the inner surface of the upper part 112 of the shoe 102 by using the hook-and-loop fastener. 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 to the upper part 112 with a thread or the like.

  In the shoe 102 accommodating the insole 4, the shoe 102 is worn so that the front tsubo 14 is located in the crotch between the first and second toes of the foot 108. When walking (running) while wearing the shoes 102, the front tsubo 14 acts on the toe crotch between the first toe and the second toe, whereby the weight shift during walking is straight from the heel to the first toe. As a result, the force of the toes can be transmitted to the sole of the shoe, and the user can stably walk (run). Further, in this walking (running) state, the front tsubo 14 acts on the toe crotch between the first toe and the second toe. This also makes it possible to stabilize walking (running), and to increase the strength of the toes and soles of the toes because kicking is more effective. As a result, the walking posture is improved, and lower back pain, knee pain, and the like can be prevented. In addition, since the outer shape of the front tsubo 14 is cylindrical, it is easy to grasp by the first toe and the second toe, thereby it is easier to step on when kicking by applying force to the toes of the toes, and to increase muscle strength of toes and soles. Can be achieved.

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

  In this modification, a lower female screw hole 56 is provided at one end of the columnar member 52, and the male screw portion 60 of the mounting screw 58 is screwed into the lower female screw hole 56 through the insole main body 4 </ b> A. Is fixed to the insole main body 4A. An upper female screw hole 62 is provided on the other end of the columnar member 52, and the male screw portion 66 of the mounting screw 64 is screwed into the upper female screw hole 62 through the upper support member 16 </ b> A. The portion is fixed to the hole-side support member 16A.

  In such a front tsubo 14A, the columnar member 52 can be formed from a metal material such as iron or stainless steel, a hard synthetic resin material, or the like. And strength. In addition, the elastic sleeve 54 can be formed from a soft synthetic resin material, a foamed resin material, or the like. With this configuration, the elastic sleeve 54 is gentle on the foot but can be applied to the crotch between the first and second toes. An insole with strong stimulation can be provided.

  In addition, as another front form of the modified example, the mounting screw 58 (or the mounting screw 64) is lengthened to allow the columnar member 52 and the upper support member 16A (or the columnar member 52 and the insole main body 4A) to pass therethrough, and the upper support is provided. A nut (not shown) may be fixed to the male screw portion 60 (or 66) projecting from the member 16A (or the insole main body 4A) by screwing. In this case, the other mounting screw 64 (or 58) is used. Is omitted. Thereby, the configuration can be simplified and the assemblability can be improved. Instead of such a configuration, the columnar member 52 is omitted, the male screw portion 60 (or 66) of the mounting screw 58 (or 64) is inserted through the elastic sleeve 54, and the back support member 16 (or the insole main body 4A) is inserted. A nut may be screwed into the male screw portion 60 (or 66) projecting from the nut and fixed.

  In the front tsubo as still another modification, the front tsubo 14A and the back support member 16A may be integrally formed of a 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. The second embodiment is different from the first embodiment in that a thin portion in which the thickness of the insole body is reduced is provided in a region including a portion supporting the toe in the toe side front portion of the insole body. Is different.

  In FIG. 9, in the insole 202 of the second embodiment, a thin portion 261 having a reduced thickness of the insole main body 204 is provided in a region including a portion supporting the toe in the toe side front portion 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.

The adjustment portion 319 may be provided by adjusting the installation position to a position closer to the thumb direction. In this case, the position can be adjusted by providing a new slit obliquely from the front tsubo 314 in the thumb direction and inserting the adjusting portion 319 into the new slit. The hallux valgus can be further corrected by increasing the opening angle between the thumb (first toe) and the index finger (second toe).

  In the third embodiment, the adjusting section 319 may have the same material and shape as the front tsubo 14. For example, a configuration may be provided that includes a hollow sleeve 18 as a flexible hollow sleeve in the above-mentioned front tsubo 14 and a pair of core cords 20 and 22 inserted through the hollow sleeve 18. The hollow sleeve 18 may be omitted and only the pair of core cords 20 and 22 may be provided. Further, the adjusting section 319 may be formed as the above-described columnar member 52 and the cylindrical elastic sleeve 54 as an elastic sleeve covering the columnar member 52. At that time, the configuration of the front tsubo 14 and the configuration of the adjustment unit 319 may be different. Further, the back support member 316, the front tsubo 14, and the adjustment portion 319 may be integrally formed.

  As described above, in the third embodiment, since the adjusting portion for adjusting the opening angle of the thumb is provided on the tip end side of the toe from the position where the front tsubo is provided, the body is pressed from the left and right. Sometimes, you can press on your toes and soles. Further, by adjusting the position, the hallux valgus of each person can be corrected.
