The inner sole for footwear is the distal phalanx of all fingers from the first to fifth fingers of the toes with the user wearing the footwear provided with the inner sole for footwear on the tip side of the body (1) There is provided a finger hooking portion (2) on which the last joint of all fingers is hooked when the interphalangeal joint, the proximal interphalangeal joint, and the metacarpophalangeal joint are bent inward.

Description

  The present invention relates to an insole for footwear and footwear for preventing or treating flat feet, for dieting and / or for training muscles and leg strength of soles. More specifically, the present invention relates to a technique for preventing or treating a flat foot by forging a muscle group for forming an arch structure (arch) on the sole of the foot by encouraging the user to expand and contract the entire toe. At the same time, the present invention relates to an insole for footwear and footwear that promotes muscle movement of the legs and legs by naturally accelerating the expansion and contraction motion of the entire toes during walking, thereby providing a diet effect. Furthermore, the present invention relates to an insole for footwear and footwear for training muscles of feet and legs such as soles, shins, calves and thighs.

Inside the human sole, there is an upwardly curved arch structure called an arch. This arch structure plays an important role in weight distribution and shock absorption during standing and walking.
In the arch structure, when the bone, ligament, and muscle that support the arch structure are damaged, the arch is lowered and flat feet are formed. It is said that flat feet tend to cause pain or fatigue in various parts of the body such as feet and hips, especially when standing for a long time or walking.

  As a means for preventing the above-mentioned adverse effects caused by being flat feet, for example, there is a “foot correction shoe sole” described in Japanese Patent Application Laid-Open No. 7-207. This shoe sole is used to correct an adductor foot known as a soft flat foot, and has a front part and a middle part of the foot, and the front part of the foot is behind the toes of the inner two fingers. The structure is such that the part that does not reach the heel is supported at a high position, and the middle part of the foot supports the middle root bone at a higher position and supports the arch.

As a result, the center of the sole can be inverted, and the height of each part of the adduction foot can be adjusted by increasing the first middle root bone and the two inner toes.
However, this shoe sole performs so-called symptomatic treatment, and cannot perform fundamental treatment or correction of the flat foot.

  To prevent or correct (correct) flat feet, train the muscles that support the arch structure of the soles (especially, the sole muscles on the sole and the posterior tibial muscle that connects the foot and leg). As a movement for that purpose, the toe standing-up movement, etc. can be considered, but in recent years, there is also the knowledge that the so-called “goo-par movement” of the toes, which is the form of the so-called toes, is effective. (Refer nonpatent literature 1). However, it is difficult to continue these exercises in daily life. In particular, when a child performs the exercise therapy, it seems that the effect is higher than that performed by an adult, but it is more difficult to instruct the child to continue such an exercise and to continue the exercise.

  In view of this, it has been proposed that footwear such as shoes used on a daily basis has a function of strengthening the muscle group of the sole of the foot so that the flat foot can be efficiently prevented or treated. As such a thing, for example, “Infant shoes and insoles” described in Patent Document 2 (Japanese Patent Application Laid-Open No. 2001-157601) and “Insole of baby shoes” described in Patent Document 3 (Japanese Patent Application Laid-Open No. 2004-254864). There are “sets and insoles”.

  These are structures in which a partition wall is erected at a position where the first finger and the second finger of the foot on the front side of the insole or shoe insole can be sandwiched. It makes it easy to move one finger and the other four fingers separately, for example, when a child walks, it can be easily moved to grab the ground with the foot, resulting in the formation of a proper arch The effect of promoting the healthy growth of the foot can be expected.

In recent years, public interest in metabolic syndrome (abbreviated as “metabo”) has increased, and there has been a strong interest in diets for preventing metabolic syndrome. Under these circumstances, a lot of diet instruments, foods, etc. have been commercialized.
Among these, as one of the diet devices, devices related to footwear such as diet shoes, diet insoles, and diet soles have been proposed.
Furthermore, there is a strong interest in leg and leg strength training, and several training footwear exists or has been proposed.

  For example, in “Shoe-inner shoe with O-leg prevention / diet function” described in Patent Document 4 (Japanese Patent Application Laid-Open No. 2007-325897), the inner side of the heel and the thumb side of the toe are used as the insole or shoe sole form ( It is devised so that the force of the sole of the foot gathers at the center when walking by providing a semicircular depression on the inside. As a result, it is an insole or shoe insole that is expected to induce muscle exercise so as to force balance of the body during walking, as well as prevent O-legs, and expect the resulting diet effect.

In addition, in the “shape-up shoes” described in Patent Document 5 (Japanese Patent Application Laid-Open No. 2006-20656), the shoe sole has a notch in the ground contact portion at the center of the sole and the stepped portion in the vicinity of the thumb ball portion, and these notches have elasticity. There has been proposed a shoe sole that is expected to have a diet effect due to an increase in exercise calories due to the undulation effect of the shoe sole that occurs during walking by embedding a volume absorber having a displacement function in the vertical direction. At the same time, they are also suggested to train leg strength by keeping balance against instability of the soles.
Furthermore, as footwear for muscular strength training, footwear for training muscular strength of legs by increasing the weight of footwear itself such as iron clogs and shoes has been well known.

However, the insole and shoes described in Patent Documents 2 and 3 have the following problems.
That is, although the partition wall makes it easy to move the first finger and the other four fingers separately, it does not promote toe movement. Therefore, when walking, if the user does not consciously exercise the toes, the effect on the arch formation cannot be expected so much.
In addition, when walking toes to move the toes to grab the ground with the feet, there is almost no hang on the partition wall, so there is little resistance to the toes, and in the sense of training the muscles of the soles The effect is not enough.

  In addition, the insoles and shoes described in Patent Documents 4 and 5 cause muscle movement by balancing the motility of the thumb and walking, resulting in an increase in muscle energy consumption. However, since the toe movement is limited to the thumb, the muscle stimulation and exercise are not sufficient, and the larger muscle stimulation and the greater energy from the exercise. Consumption is desired.

(Object of the present invention)
It is an object of the present invention to perform the movement of a user's toes such as an insole or insole of a shoe such as a shoe insole, in particular, an expansion / contraction movement that moves the toes so that the ground is repeatedly grabbed by the feet. (Goo-Per-exercise) is a structure that can be actively promoted, and the toes can be exercised naturally even when the user is not conscious at the time of walking. It is to provide an insole for footwear and footwear that can be effectively performed.

In addition, as another object of the present invention, it is not a partial motion such as a thumb as a toe, but a “goo-par motion” is forcibly urged when walking with all toes. Compared to the lower limb and upper limb muscles, by providing greater and stronger stimulation and exercise, the consumption of kinetic energy is increased and the footwear insole and footwear have a greater diet effect.

It is restored and installed so that there is no sense of incongruity of the sole including the toes in the extended state, and it is recommended to use an elastomer resin or the like, but in the present invention, the material that achieves the function If it is, it will not be specifically limited.

(Work)
The action of the insole for footwear and the footwear for the prevention or treatment of flat feet according to the present invention, for dieting and / or for the training of muscles and leg strength of the soles will be described. Here, the constituent elements used in the description are assigned in correspondence with the reference numerals given to the respective parts in the embodiments described later. These reference numerals are the same as the reference numerals described in the claims of the claims. Similarly, it is only for the purpose of facilitating the understanding of the contents, and the meaning of each component is not limited to each of the above parts.

The insole for footwear for the prevention or treatment of flat feet, diet and / or training of muscles and leg strength of the foot according to the present invention is positively applied to all toes (first finger which is a thumb) during walking. To all the fifth fingers (small fingers) to promote expansion / contraction (finger goo / par).
As mentioned above, the muscles that support the arch structure (arch) of the soles (especially the sole muscle group on the soles, the feet and lower legs) The tibia muscles etc. that are tied are trained to promote the formation of arches and prevent or treat flat feet.
Furthermore, in addition to the muscle group, the thigh muscles and calf muscles are also loaded, and a large energy consumption is promoted as compared with normal walking, and a diet and shape-up effect is expected. At the same time, because it trains the legs and local muscles, it is also effective in strengthening muscle strength.
A shoe insole as shown in FIG. 1 according to the present invention is inserted into a shoe and used on a shoe sole. When the user puts on the shoes, all five toes are hung so that the depression on the back side of each toe covers the finger-hanging portion (2).
When the user walks in this state, from the grounding of the shoe to the kicking-up, each toe is naturally forced in the direction of inward bending, and so-called “foot movement” of the foot junken is performed. When each toe makes a “goo movement”, the end node of each toe is strongly hooked on the finger hooking portion (2), and a force acts in a direction in which the toe portion of the main body (1) slides backward and contracts. As a result, the center part of the insole of the present invention is raised. (Because the heel part, the last part of the insole of the present invention, the back part of the shoe serves as a stopper and does not slide.)

Also, from the kicking up of the shoe to the grounding, each toe is relaxed and extended from the “goo” state, and becomes a so-called “par” state of the foot junken. Along with this, the force applied to the finger rest (2) by each toe is released. As a result, the insole of the present invention is released by the force applied when it rises, so that the toe side slides forward and returns to its original position due to the repelling force of the insole (force to return strain). Restored.
In this way, by using the insole, the inward bending / extension movement (goo-par movement) of each toe was naturally provided with the walking of the user, or the finger hanging part (2) was provided. By repeatedly doing so as to be actively encouraged by the structure, the muscle group that supports the arch structure of the user's sole is trained. Thereby, the arch structure of the sole, that is, formation of an arch or prevention and treatment effects of flat feet can be expected. Furthermore, as mentioned above, the muscles of the thigh, shin, and calf are also trained at the same time, which promotes a large energy consumption compared to normal walking, and is expected to have a diet and shape-up effect. At the same time, because it trains the muscles of the feet and local areas, it is also effective for the training of strength.

  When the main body is formed of a material having flexibility or deformability, and the main body is provided with a notch portion that facilitates deformation in the longitudinal direction (see FIG. 2), In this case, the slides are easy to slide, and in both cases, the degree of freedom in moving the toes is increased. Furthermore, if the main body is made of a material having a property that causes a smaller frictional force against the inner surface of the shoe sole, the main body can be more effectively slid in the heel direction and the toe direction. Further effects can be obtained. In addition, during the “goo movement”, the width of the notch is narrowed and the insole is deformed and distorted. When the “goo motion” shifts to the “par motion”, the insole is restored to its original form by the repulsive force generated by the strain.

Like the insole shown in FIG. 2, the main body is provided with, for example, a triangular notch (3) that facilitates deformation in the longitudinal direction, and the notch (3) is provided on the upper surface side of the main body (1). What is covered with the cover (4) can alleviate the discomfort of the user's sole due to the provision of the notch (3).
The cover (4) is fixedly connected so as to close the notch (3). If it is not fixedly connected, the position of the expansion / contraction (goo-par) movement will shift during walking, and the effect of alleviating the feeling of discomfort on the soles will be impaired.
As the form of the fixed connection, it is preferable to select either the form fixed on the toe side of the triangle formed by the notch portion or the form of fixing both sides of the toe side and the heel side knitting.
If the part along the heel side of the triangle is fixed and not fixed along the side of the toe side, the main body part on the toe side of the notch part will be Since they are attracted to each other, they are easily caught between the toe side of the triangular cover and the sole, which may cause a sense of incongruity. In addition, as a method of fixed connection, any method can be used as long as the cover and insole can be bonded and bonded and fixed, but for example, a method that is easy to perform sewing, bonding with an adhesive, etc. Illustrated.

As another embodiment of the present invention, as a means for actively promoting the expansion / contraction movement of all fingers from the first to fifth toes during walking, an insole as shown in FIG. The shape of the inner bottom for footwear such as the main body (1) is formed by cutting off a part of the tip (toe) side or by molding it into the same shape, for example, it is formed with the thickness part of the insole main body (1) If there is a dent with a certain depth on the toe part of the shoe sole, there will be a large space at the toe and tip, and the space where the toes will move will increase. The expansion and contraction (goo-par) movement becomes easier and the effect can be expected.
At this time, the toes are easily caught by providing a finger hook portion having a thickness of the insole main body or a thickness greater than the depth of the dent at the front end of the cut portion of the insole or at the boundary portion of the insole bottom recess portion. And more effective exercise is possible.

  As shown in FIG. 5, when the shape of the main body (1) is made into a footwear insole of a shape in which a part of the tip side is cut off or molded into an insole for footwear of the same shape, as shown in FIG. Those with a soft finger holder (15) that does not interfere with the movement of bending the toes in the excised or recessed part of the bottom relaxes (extends) the toes. Sometimes, each toe can be stably held by the finger placement part (15). As a result, a sense of incongruity during walking is reduced, and comfortable walking exercise is possible.

  The footwear (S) in which the insole for footwear is integrally formed for prevention or treatment of each flat foot, for dieting and / or for training of muscles of the soles and leg strength, The present invention can be used as footwear having the same action as footwear using an inner bottom for footwear.

(A) In the present invention, the structure of an insole (insole), the sole of a shoe, etc. is applied to the movement of a user's toes, particularly toe expansion / contraction movements that move the toes so that the ground is repeatedly grabbed by the feet.・ A structure that can actively promote high-momentum (par exercise), and can naturally exercise toes effectively even if the user is not particularly conscious during walking. It is possible to provide an insole for footwear and footwear that can be expected to have a therapeutic effect, a diet effect, and / or a training effect such as leg strength.

(B) In the present invention, when the toes are moved so as to grab the ground by the feet during walking, there is a hook and / or a sufficient space for toe expansion / contraction motions, so that a large motion of the toes It is possible to promote strong exercises of the toes, and a sufficient effect can be expected in the sense of strengthening the muscle groups of the soles and upper and lower limbs.

The effect | action of 4th Embodiment of a shoe insole is shown, (a) is sectional explanatory drawing of the state which extended the toe, (b) is sectional explanatory drawing of the state which bent the toe. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a shoe according to the present invention, where (a) is a cross-sectional explanatory diagram in a state where the toes are extended, and (b) is a cross-sectional explanatory diagram in a state where the toes are bent inward.

  The present invention will be described in detail based on the embodiments shown in the drawings.

The structure of the shoe insole A1 will be described with reference to FIG. The shoe insole A1 is a shoe insole for preventing or treating a flat foot used in a shoe sole, for dieting, and / or for training muscles and leg strength of a sole (a shoe insole or a shoe described later). The same applies to the inner bottoms A2 to A5).
The insole A1 has a required thickness and includes a so-called foot-shaped main body 1. The main body 1 is made of a slightly hard urethane as a material, and has a required elasticity, flexibility, or a deformability having a required strength restoring property.

  Near the top end of the upper surface of the main body 1, a finger hooking member 2 protruding upward is fixed at a predetermined interval from the front end. The finger hooking member 2 is provided in the width direction of the main body 1 in the length direction, and has a length extending over almost the entire width. The finger hooking member 2 is provided in the shape and position corresponding to the dent on the back side of all the five toes 7 of the user or the tip 71 (see FIG. 6) slightly from the dent. You can hang it. What is important is that the toes are designed so that there is as little play as possible between the toes and the finger-hanging part when the toes start inward bending (goo movement) and during inward bending movements. As a result, the expansion / contraction (goo-par) exercise at the time of walking can be promoted more efficiently and with a large amount of exercise. Further, the finger-hanging member 2 is formed of a synthetic resin having a strength sufficient to withstand the force acting when all fingers are hooked and each toe is bent inward. In addition, the finger hook member 2 can also be provided in the main body 1 by integral molding.

In addition, in order to promote the toe expansion and contraction movement more greatly and efficiently during walking, the frictional force between the bottom of the insole in contact with the shoe sole and the bottom of the shoe in contact with the insole is reduced, and more It is recommended to use a structure and / or material that the insole is on the inner surface of the shoe and is slippery during toe movement.
This is because the contact surface between the insole and the sole is made slippery so that the contact part with the shoe sole from the tip of the insole to the center part during the internal bending of the finger (contraction movement / goo movement) As a result, the resistance between the sole and the insole is small, and the insole can slide greatly in the heel direction. As a result, the toes are bent more greatly, and as a result, the toes have a larger momentum, and the effects of the present invention can be obtained more greatly.
In the present invention, as described above, at least from the center part of the sole of the insole, with respect to the toe portion, with respect to the contact portion with the shoe sole, the frictional resistance at the contact surface is reduced, and the portion is in the shoe sole. It is preferable to slide backward (in the heel direction).

Next, the structure of the shoe insole A2 will be described with reference to FIG.
The shoe insole A2 has a structure equivalent to that of the shoe insole A1 and further provided with a notch 3 and a cover 4.
The cutout portion 3 is provided in a substantially V-shaped cutout at an approximately middle portion in the longitudinal direction of the main body 1 so as to open in an inward direction. A hole 30 is provided at the tip of the notch 3 to prevent this portion from becoming a base point for tearing.
By providing the notch 3, the inner toe movement of the toes during walking is easier and larger, and slides in the heel direction where the toe side portion of the insole is behind. As a result, a greater expansion / contraction motion of the finger is achieved, and the effect of the present invention can be increased.
As shown in FIG. 2, the shape of the notch 3 is preferably notched in a triangular shape. By cutting out into triangles, the slide in front and back of the insole can be achieved more effectively, and the above-described great effect can be obtained.

In this case, the part that slides in the insole is mainly the part forward (toe side) from the notch. Therefore, in contact with the shoe bottom surface of this portion, reducing the frictional force as much as possible slides the insole more effectively.
In addition, the presence of the hole 30 is not particularly limited, and the present invention can be carried out without the hole 30, but the presence or absence of the hole causes the toe to expand or contract during walking (goo Par) When the front part (toe side part) slides back and forth in the heel direction and the toe direction from the notch of the insole, it is possible to alleviate the uncomfortable feeling given to the sole of the foot. Moreover, as described above, it is possible to prevent the insole from being broken.
Further, the shape of the hole 30 is not particularly limited in the present invention, but it is preferably a circular shape from the viewpoint of durability of the insole described above and relaxation of a feeling of strangeness on the sole.

In the insole A2 of the present invention shown in FIG. 2, a cover 4 that covers the notch is attached.
The material of the cover 4 is not particularly limited in the present invention, but is preferably a material having flexibility. In this embodiment, the cover 4 is formed into a triangular shape using a material formed of a soft urethane in a sheet shape. Is formed. The cover 4 is fixed to the upper surface side of the main body 1 by sewing two sides along both edges of the cutout portion of the cutout portion 3, thereby closing the cutout portion 3.
The cover 4 is provided to relieve a user's discomfort on the sole of the foot due to the provision of the notch 3 by closing the notch 3.
Further, the fixing of the cover 4 is not particularly limited in the present invention. Even if the cover 4 is not fixed, there is no problem if the cover covers the notch and does not shift during walking. Thus, such a deviation can be surely prevented.

Further, the fixing method of the cover 4 is not particularly limited in the present invention. As described above, the cover 4 may be fixed by sewing, or may be fixed by an adhesive or the like.
The fixing position / portion may be fixed along both edges of the cutout portion of the cutout portion 3 as in this embodiment, or one of the edge portions may be fixed.
In the case of fixing one edge, it is preferable to fix the edge on the toe side among both edges. When only the heel-side edge is fixed, the insole will bend inward during expansion / contraction during walking, and when the toe part slides backward (in the heel direction) from the notch 3, The cover may feel strange and the cover may turn over.
Such a problem is alleviated when only the edges on both toes are fixed. However, when wearing shoes with such insoles, if only one edge, which is the toe side part of both edges, is fixed, there is a risk of turning when inserting the foot when wearing shoes, It is usually recommended to fix both edges.

The structure of the shoe insole A3 will be described with reference to FIG.
When the insole A3 is inserted into a shoe as an insole, the insole material does not need to be particularly flexible or deformable, and has a certain degree of hardness such as relatively hard leather or hard urethane. A material that does not give excessive stimulation to the sole of the foot is used as a material, and it is formed only with a main body having a required thickness (about 5 to 10 mm in the present embodiment). The thickness of the insole A3 is not limited to this, and the toe is sufficiently stretched / retracted (goo-par) in the toe portion that is a part to be cut and hung by a finger. If there is no problem in securing the space, it can be set to an appropriate thickness. In particular, it is preferable to set the thickness according to the length of the toe that varies depending on the person. From this, it is preferable that the thickness of the main body (also for the dent described later) is equal to or longer than the height of the finger hooking member 2 in the insole described above. The shoe insole A3 is higher in rigidity than the main body 1 of the shoe insoles A1 and A2, and is not easily deformed. However, the shoe insole A3 may be formed of the same material as each main body 1 to have the same deformability.

  The sock insole A3 has a shape in which a part on the front end side of the foot-shaped main body is cut out. The tip surface shape of the finger-hanging portion 10 is formed in a gentle arc shape in which the central portion in the width direction slightly bulges outward. The finger hooking portion 10 is provided at a position corresponding to the depression 71 on the back side of all the five toes 7 of the user so that all fingers can be hooked on the finger hooking portion 10.

The structure of the shoe insole A4 will be described with reference to FIG.
The shoe insole A4 includes a main body 1a having a two-layer structure. The lower layer portion 11 of the main body 1a is formed in a foot shape using a synthetic resin such as leather or hard urethane as a material. The upper layer portion 12 bonded to the upper surface of the lower layer portion 11 is also formed of a synthetic resin such as leather or hard urethane, and the main body 1a and the lower layer portion 11 are integrated, so to speak, on the tip side of the foot-shaped main body. It is a shape that is partly excised. The finger hooking member 13 is bonded to the distal end surface 120, which is a portion of the upper layer portion 12 cut out, with the upper end slightly protruding from the upper surface of the upper layer portion 12.
In practicing the present invention, the finger-hanging member does not necessarily have to be attached, and the cut surface of the main body 1a can be substituted.

The shape of the finger hooking member 13 or the cut surface is not particularly limited as long as the finger is applied to the finger hook member 13 or the cut surface. For example, the shape of the cut surface 10 in FIG. 3 may be used, but like the tip surface 130 in FIG. A shape that is curved so as to substantially conform to the back surface shape of the terminal node of all five toes of the user is also preferable. In the case of installing the finger hanging member, the finger hanging member 13 is preferably formed of a material having stronger elasticity and restoring force than the main body 1a formed of synthetic resin such as leather or hard urethane. In the present embodiment, a slightly hard urethane foam is used, but the present invention is not limited to this.
The finger hooking member 13 is provided at a position corresponding to the depression 71 on the back side of all the five toes 7 of the user so that all fingers can be hooked on the distal end surface 130.

Since the shoe insole A4 is provided with the foot-shaped lower layer portion 11, when used as a shoe insole, the shoe insole A4 is more stable because the position does not shift in the shoe compared to the shoe insole A3. .
Further, the finger hooking member 13 is provided such that the upper end slightly protrudes from the upper surface of the upper layer portion 12, and the toes of each toe are better compared to the shoe insole A3.

The structure of the shoe insole A5 will be described with reference to FIG.
The insole A5 is formed in a foot shape as a whole and includes a main body 1b. The main body 1b uses a synthetic resin such as leather or hard urethane as a material, and is so-called a part of the foot-shaped main body that is cut off, and is the same as the main body 1a in FIG. However, regarding the thickness of the main body 1b, it is preferable to make it thicker than the thickness of the main body 1a.
And the front end surface used as the part which the main body 1b removed is the finger-hook part 14. In FIG. The shape of the finger hanging portion 14 is the same shape as the distal end surface 130 of the finger hanging member 13 of the shoe insole A4. In addition, the present invention can be implemented without installing the finger hook portion 14 by making the tip surface of the main body 1b have the same shape.

  A finger rest 15 is in close contact with the cut surface of the finger rest 14 or the main body 1b having the same form as the finger rest 14 so as to be continuous therewith. The finger placement part 15 has the same thickness as the main body 1b and has a shape that forms a foot shape as a whole of the shoe insole A5 by being integrated with the main body 1b. The finger rest portion 15 is formed of a material having elasticity and restoring force as compared with the main body 1b formed of a synthetic resin such as leather or hard urethane. It has a softness that does not hinder the operation of hanging. In other words, in order to smoothly promote all toe expansion and contraction during walking, it is sufficiently depressed during internal flexion, which is a contraction, and in close contact with the back of the toes during expansion (toe extension), the shape is restored. Is done. In the present embodiment, an elastomer (elastomer) such as soft urethane is used as the material for the finger placement unit 15, but the present invention is not limited to this.

As described above, the material for the finger placement part 15 is sufficiently depressed or expanded (extension of the toes) during the internal bending movement, which is a contraction movement, so as to smoothly promote the expansion and contraction movement of all toes during walking. Sometimes, any material can be used as long as it can adhere to the toe back surface. As a specific example, elastomers such as the above-mentioned soft urethane, silicone resin, etc., and for example, a space portion of a two-layer sheet of these elastomers has an elastomer pillar (pillow / pillar) upright, and a space is maintained between the two layers. And a hollow elastomer molded body, a spongy material, and the like.
Compared with the insole of FIG. 3 or FIG. 4, the discomfort of the soles in the state of wearing shoes is alleviated by installing the finger placement unit 15.
In addition, it is preferable that the thickness of the finger placement portion 15 is basically the same as the thickness of the main body 1b in order to avoid a feeling of strangeness of the entire sole. As described above, the thickness of the insole A3 main body shown in FIG. The thickness depends on the degree of compression of the finger holder 15 when the finger of the finger holder 15 is bent, and differs depending on the individual material. However, the thickness is sufficient to achieve a sufficiently large finger expansion / contraction motion during walking. Preferably there is.

3 to 5 used in the present embodiment, these shoe insoles are directly bonded to the shoe insole (shoe insole), in other words, the shoe insole is shown in FIG. 5 are also included in the present invention.
In the case of an integrated shoe insole, which has the same functions and configurations as the insole shown in FIGS. 3 to 5 compared to the insole, the individual insole directly compared to the insole Therefore, it is possible to further reduce a sense of incongruity when wearing shoes or walking.

(Work)
Taking the shoe insole A2 and the shoe insole A4 as an example, the operation when these are laid on the inner bottom of the shoe will be described.

First, with reference to FIG.2 and FIG.6, the effect | action of shoe insoles A2 is demonstrated.
(1) Insert the insole A2 into the inside of the shoe 5 and lay it on the sole (sole) 50 of the shoe 5. When the user puts on the shoes 5, all five toes have a depression on the back side of each toe 7 or a portion close to the depression on the back of each toe (a position in the toe direction slightly from the depression) 71 on the finger-hook member 2. It is hung so as to cover it (see FIG. 6A). When the user walks in this state, the shoe insole A2 acts as follows.
When the position of the finger hanging member 2 is located on the heel side from the toe back side depression 71, even if the toe tries to perform “goo movement”, an effective repulsive force from the finger hanging portion to the toe is not obtained, and as a result Not enough insole slides. As a result, since a semi-unconscious toe “go-par motion” does not occur, the presence of the finger-hook member 2 itself is lost. Moreover, if the position of the finger hooking member 2 is too far from the depression on the back side of the toes, the toes will not effectively touch the finger hooking member 2, and the effective effect of the present invention will not be obtained.

(2) During walking, from the grounding of the shoe 5 to the kicking-up, each toe 7 is naturally forced in the direction of inward bending, and the so-called “foot movement” of the foot junken is performed. When each toe 7 performs a “goo movement”, the end node 70 of each toe 7 is strongly hooked on the finger hooking member 2, and the force that the main body 1 of the shoe insole A 2 contracts in the heel direction acts. By this force, the front end side of the main body 1 slides so as to reduce the distance between the front and rear of the notch 3. At this time, the cover 4 covering the notch 3 is deformed so as to be curved upward, and at the same time, the interval between the notches of the insole body is deformed and narrowed, and is distorted in the vicinity of the notch. (See FIG. 6 (b)).

(3) Also, from the kicking up of the shoe 5 to the grounding, each toe 7 is relaxed and extended from the “goo” state, so that it becomes a so-called “par” state of the foot junken (see FIG. 6A). ). Along with this, the force applied to the finger hooking member 2 by each toe 7 is released, and the main body 1 is released from the distortion and returned to its original stretched state by elasticity. As described above, as the user walks, the inflection / extension movement (goo-par movement) of each toe 7 is naturally urged with a large momentum or the structure provided with the finger hanging member 2. By repeatedly performing as described above, the muscle group supporting the arch structure of the user's sole is trained, which can contribute to the formation of an arch structure, that is, an arch or prevention of flat feet. In addition, since each toe 7 is often moved inside the shoe 5, an effect of preventing or treating hallux valgus can be expected.

  About the effect of shoe insoles A2, it is not necessarily only the prevention and treatment of flat feet. For example, the inward bending / extension movement of each toe 7 can be performed naturally or semi-forcefully, so that the amount of exercise of both the shin muscle and the calf muscle and the thigh muscle is normal. Since it increases compared to walking with shoes, resulting in an increase in energy consumption, a diet effect is brought about. At the same time, it also has the effect of increasing leg strength.

  For this reason, it can also be used as a sport performance-enhancing device for the purpose of strengthening the ability of running or training the legs. Further, as described above, by simply walking using the insole A2, the exercise of the muscle group of the sole part, the shin part, the calf part, and the thigh part is naturally or forcibly forced (or promoted). Therefore, the amount of exercise in walking increases, and it can be used for footwear such as shoes for dieting and shaping up.

  Unlike the shoe insole A2, the shoe insole A1 is not provided with the notch 3. However, the main body 1 has the same action as the shoe insole A2 by using the elastic deformation as a restoring force. , Have an effect.

Next, with reference to FIG.4 and FIG.7, the effect | action of shoe insoles A4 is demonstrated.
(1) Insert the insole A4 into the shoe 5 and place it on the sole 50 of the shoe 5. When the user puts on the shoes 5, the five toes cover the finger resting member 13 in the vicinity of the depression 71 on the back side of each toe 7 or the toe depression slightly on the heel side from the back side of the toes. (See FIG. 7A). When the user walks in this state, the shoe insole A4 acts as follows.

(2) During walking, from the grounding of the shoe 5 to the kicking-up, each toe 7 is naturally forced in the direction of inward bending, and the so-called “foot movement” of the foot junken is performed. When each toe 7 performs “goo movement”, the end joint 70 of each toe 7 is strongly hooked on the finger hooking member 13, and a force acts in a direction in which the main body 1 a of the shoe insole A 4 contracts. The main body 1a is made of leather, hard urethane, or a normal synthetic resin that does not have flexibility. Even if this force is applied, the body 1a does not bend or hardly bends and hardly deforms. A sufficient load is applied to each toe 7. At the same time, the positional relationship between the finger-hanging member and the sole in the toe extension (par state) is larger by positioning it in the vicinity of the heel slightly shifted from the dent or dent of each toe as described above. The range of motion of the toes is ensured, and the effects of the present invention can be exhibited more efficiently. Of course, if the position of the finger-hanging member is shifted too much in the heel direction, each toe cannot obtain a sufficient repulsive force in the “goo” state. In addition, when the toes are located closer to the toes than the toes of each toe, effective fingertip movement cannot be achieved. In FIG. 7B, slight deformation of the main body 1a is not shown for convenience of illustration.

(3) Further, from the kicking up of the shoe 5 to the grounding, each toe 7 is relaxed and extended from the “goo” state to a so-called “par” state of the foot junken (see FIG. 7A). ). Along with this, the force applied to the finger hooking member 13 by each toe 7 is released, and the main body 1a returns to its original state due to its elasticity.
As described above, as the user walks, a large inward bending / extension movement (goo-par movement) of each toe 7 is naturally promoted or actively encouraged by the structure provided with the finger hooking member 13. By performing repeatedly, the muscle group which supports the arch structure of a user's sole is trained similarly to said shoe insole A2, and it can contribute to formation of an arch structure, ie, an arch, or prevention of a flat foot. Moreover, since each toe 7 is moved well inside the shoe 5, the effect of prevention or treatment of hallux valgus is also obtained. Note that the shoe insole A4 is more effective than the shoe insole A2 because the space where the toes 7 move is larger, making the movement easier.

  The effect of the shoe insole A4 is not necessarily just the prevention and treatment of flat feet, as in the case of the shoe insole A2. For example, the inflection / extension movement of each toe 7 can be performed naturally or semi-forcedly, which leads to strengthening of the muscles of the shin, calf and thighs, and the leg strength. The effect of strengthening can also be obtained.

  For this reason, it can also be used as an instrument for enhancing sports ability for the purpose of strengthening running and training of the legs. In addition, just by walking using the insole A4, the exercise of the muscle group of the foot is promoted (or promoted) naturally or semi-forced, so that the amount of exercise in walking increases, for example, It can also be used for footwear such as shoes for shape-up purposes.

  The insole A3 can be used in substantially the same manner as the insole A4. Unlike the shoe insole A4, the shoe insole A3 is not provided with the finger hanging member 13, so that the hook of each toe on the finger hanging portion 10 is slightly inferior to the shoe insole A4. There is also an advantage that the sense of incongruity felt on the back side is reduced, and overall, it has almost the same operation and effect as the insole A4.

The structure of the shoe S according to the present invention will be described with reference to FIG.
The shoe S which is footwear is a shoe insole 6 which is an inner bottom for footwear.
The shoe inner sole 6 has a structure substantially equivalent to the shoe insole A5.
In FIG. 8, the same or equivalent portions as the insole A5 are denoted by the same reference numerals, and redundant description of the structure is omitted.

(1) When the user wears the shoes S, all five toes are in the extended state of the toes, and the depressions 71 on the back side of the toes 7 or the vicinity of the back side of each toe slightly from the depressions Cover the finger rest 14. In the extended state of each toe 7, that is, during normal relaxation, each toe 7 is stably held by the finger rest 15 deformed so as to be depressed (see FIG. 8A). When the user walks in this state, the sole 6 of the shoe S acts as follows. The positional relationship between the soles and the finger rests 14 is the same as the positional relationship described in the above-mentioned shoe insole A4.

(2) During walking, from the ground contact of the shoe S to the kicking-up, each toe 7 is naturally forced in the direction of inward bending, and the so-called “foot movement” of the foot junken is performed. When each toe 7 performs “goo movement”, the finger rest 15 is pressed by the end joint 70 or the fingertip of each toe 7 to be further depressed, and the end joint 70 is hooked on the finger hook 14. Thereby, force acts in the direction in which the main body 1b of the shoe sole 6 of the shoe S contracts. The main body 1b is made of leather, hard urethane, or a normal synthetic resin that does not have flexibility. Even if this force is applied, the main body 1b does not bend and hardly deforms. Sufficient load is applied. At the same time, the positional relationship between the finger-hanging member and the sole in the toe extension (par state) is larger by positioning it in the vicinity of the heel slightly shifted from the dent or dent of each toe as described above. The range of motion of the toes is ensured, and the effects of the present invention can be exhibited more efficiently. Of course, if the position of the finger holding member is shifted too much in the heel direction, each toe cannot obtain a sufficient repulsive force in the “goo” state. In addition, when the toes are located closer to the toes than the toes of each toe, effective fingertip movement cannot be achieved. In FIG. 8B, slight deformation of the main body 1b is not shown for convenience of illustration.

(3) Further, from the kicking up of the shoe 5 to the grounding, each toe 7 is relaxed and extended from the “goo” state to a so-called “par” state of the foot junken (see FIG. 8A). ). Along with this, the force applied to the finger hook 14 by each toe 7 is released, and the main body 1a returns to its original state due to its elasticity. Further, when each toe 7 changes from the “goo” state to the “par” state as described above, the movement of each toe 7 is assisted by the elasticity (restoring force) of the finger placing portion 15.
In addition, it is preferable that the thickness of the main body 1b and the finger rest part 15 is the same thickness in order to relieve a sense of discomfort when wearing shoes. The thickness, the position of the finger rest, the material and the like are the same as those described in the shoe insole A5.

  As described above, as the user walks, a large inward bending / extension movement (goo-par movement) of each toe 7 is naturally promoted or actively encouraged by the structure provided with the finger-hanging portion 14. By performing repeatedly, the muscle group which supports the arch structure of a user's sole is trained similarly to said shoe insoles A2 and A4, and it can contribute to formation of an arch structure, ie, an arch, or prevention of a flat foot. Further, since each toe 7 is often moved inside the shoe S, the effect of preventing or treating hallux valgus is obtained.

  As for the effects of the shoes S, as in the insoles A2 and A4, not only the prevention and treatment of flat feet, but also, for example, the inflection / extension movement of each toe 7 is naturally or semi-forced. Therefore, the muscles of the shin portion, the calf portion, and the thigh muscles are strengthened, and the leg strength is also enhanced.

  For this reason, the shoe S can be used as an instrument for enhancing the ability of sports for the purpose of strengthening running and training of the legs. In addition, simply walking with shoes S naturally or half-forcedly promotes (or encourages) the exercise of muscles in the sole of the foot, increasing the amount of exercise during walking, such as dieting and shaping up. Can also be used as a shoe for the purpose.

Needless to say, when the shoe insole A5 is used in a shoe, it exhibits the same action and effect as the shoe sole 6 of the shoe S.
Further, the shoe insoles A1, A3, A4 other than the shoe insole A2 can be built into the shoe as a shoe sole in the same manner as A5.

  The terms and expressions used in this specification are merely explanatory and are not limiting at all, and exclude terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to do. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.

  According to the present invention, the structure of a shoe insole (insole), shoe sole, etc. is used to move the toes of the user, particularly toe expansion / contraction movements that move the toes so that the ground is repeatedly grabbed by the feet. (Par exercise) can be actively promoted to a high momentum, and the toe can be naturally and effectively exercised even when the user is not particularly conscious during walking. It is possible to provide an insole for footwear and footwear that can be expected to have a therapeutic effect, a diet effect, and / or a training effect such as leg strength.

  Further, according to the present invention, when the toe is moved so as to grab the ground by the foot during walking, there is a space for the toe and / or sufficient toe expansion / contraction motion. Exercise and strong toe exercise can be promoted, and a sufficient effect can be expected in the sense of strengthening muscle groups of the soles and upper and lower limbs.
