Description

  The present invention relates to a shoe insole pad and a related technique in which the height of the shoe sole, the lateral width of the shoe, and the like are appropriately adjusted by being placed on the bottom of the shoe (the shoe sole). In particular, the present invention relates to an insole pad for shoes and related technology that can advantageously provide walking support while suitably obtaining a sense of unity between shoes and feet during use.

  Conventionally, an insole placed on the insole of a shoe is known. Such an insole is often used for the purpose of so-called shoe fitting, for example, matching the shape and size of a shoe with the shape and size of a foot. Insoles with air permeability, deodorant function, cushion function, etc. are also commercially available.

  However, many insoles are simply a plate having a substantially constant thickness dimension formed into a foot shape. In this case, an effective effect cannot be expected with respect to shoe fitting, foot support during walking, and the like.

  In view of such problems, some highly functional insoles have been proposed. For example, in the insole shown in Japanese Patent Application Laid-Open No. 2000-287705 (Patent Document 1), Japanese Utility Model Laid-Open No. 6-24504 (Patent Document 2), etc., a pad is provided at a predetermined location so It is applied to a portion protruding by a heel or the like, or a portion that is likely to protrude, and by restricting the protruding deformation of the portion, correction of the hallux valgus or the like is realized.

  However, since only the part protruded by the hallux valgus is only pressed locally, there is a possibility that the pressure is concentrated only on the protruding part and the walking is painful. Moreover, it was never an effective treatment just by forcing the protruding part with the hallux valgus.

  In the examination of Japanese Patent Application No. 2004-72864, which was the basis of the domestic priority claim of this application, Japanese Patent Application Laid-Open No. 11-222602 (Patent Document 3) and Utility Model Registration No. 3096443 (Patent Document 4) Quoted. In these Patent Documents 2 to 4, a plate-like insole that is overlaid on the insole, the thickness dimension of the insole is static throughout the entire area from the base of the toes to the vicinity of the heel. A structure that is continuously changed along the shape is disclosed.

  However, like the insole disclosed in Patent Documents 2 to 4, simply by matching with the static shape of the sole, it can be said to be a dynamic gait while sufficiently supporting many bones forming the foot. It is impossible to achieve effective assistance during movement.

  In particular, it is almost undesired to fit an off-the-shelf shoe whose internal shape is limited to each individual's differently shaped foot. For example, the size of the length of a shoe is generally in increments of 5 mm, and a shoe with a specific design often has only one type of shoe having a different width dimension for each length size. In that case, it can be easily understood that fitting with only the insole laid on the shoe sole is extremely rough.

  In addition, as described in Patent Document 3 and Patent Document 4 above, an insole that has been flattened as a whole and only has its thickness changed in accordance with the shape of the sole that is statically placed on a flat plate is already abnormal. Almost no therapeutic effect can be expected for deformed foot bones. In addition, if the insole is simply laid on the sole, the overall depth of the shoe will be reduced by wearing it. There is a problem in that the shoe protrudes upward, and the opening peripheral edge of the shoe is not easily caught in the bag, and the shoe is easily removed. In addition, with an insole that only matches such a static sole shape, it may not be able to follow the deformed sole shape during dynamic walking, and it may even be difficult to walk on the contrary. It ’s not difficult to imagine.

  In addition, it can be understood that the insole itself is often not flat, especially considering women's shoes, especially high heels. In such a case, as described in Patent Documents 3 and 4 described above, it should be understood that an insole that is flat as a whole cannot always exhibit the intended effect.

  In addition, in the examination of Japanese Patent Application No. 2004-72864, which is the basis of the domestic priority claim of the present application, Utility Model Registration No. 3058953 (Patent Document 5) is also cited. In this gazette, in addition to the main body part laid under the tip part of the foot, the shoe inner sheet having a non-slip function by integrally providing both side parts that are superimposed on the left and right sides of the tip part of the foot Is disclosed.

  However, the inner seat shown in Patent Document 5 is merely for preventing the foot from slipping forward in the shoe with high heels or the like, and in order to narrow the width of the spread shoe inside, both It only provided the side part. Accordingly, both side portions are positioned so as to sandwich the midfoot point between the shin side and the heel side of the metatarsal bone from both sides so as to prevent the slipping of the tip of the foot. This is the same as when the most protruding portion of the hallux valgus is intensively pressed from the outside, and the external force acts intensively and is likely to cause pain. In addition, it is considered effective to sandwich the front of the foot from the midfoot point of the shin side and the heel side with both side parts in order to prevent forward slipping. There is a risk that the abnormality will be further advanced.

  In short, the inner seat described in Patent Document 5 has only the purpose of preventing the slipping forward in the inclined shoe sole such as high heels. In terms of support, it is hardly effective. In particular, even in the central portion of the inner seat, it is merely provided with a mere plate cushion having a substantially constant thickness dimension as a whole, and this can effectively demonstrate an effective support function during walking. It was not.

  Here, the present invention has been made in the background as described above, and the problem to be solved is that the pad part that assists a predetermined part of the foot moves the foot and shoes during walking. Provided with insole pads for shoes and shoes with a novel structure that can be advantageously deformed following a change in the environment and effectively assisting the relevant part, so that the fitting function and walking support function of the shoes can be advantageously exhibited. There is to do.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible. Further, aspects or technical features of the present invention are not limited to those described below, but are described in the entire specification and drawings, or an invention that can be understood by those skilled in the art from those descriptions. It should be understood that it is recognized based on thought.

(Aspect 1 of the present invention)
A feature of aspect 1 of the present invention is that it is a single sheet insole pad for shoes that is used by being superimposed on the insole of a shoe, and is (i) located at the front part. A swollen front bottom pad portion, (ii) a rear bottom pad portion swollen at the rear, (iii) an inner lateral pad portion bulged at the inner side and extending in the front-rear direction, and (iv) Four pad portions, which are located on the outer side and swell and extend in the front-rear direction, are provided so as to be elastically deformable, and a first gap between the front bottom pad portion and the rear bottom pad portion is provided. By making it bendable as a thin portion, and allowing bendability between the front bottom pad portion and the rear bottom pad portion and the inner and outer lateral pad portions as second and third thin portions, respectively. In a state of being attached to the insole of the shoe, A lateral arch is assisted by the anterior bottom pad portion, and a lateral arch at the tarsal bone is assisted by the posterior bottom pad portion, and further on both sides of the metatarsal on the shin side and the metatarsal on the heel side In the insole pad for shoes, the inner lateral pad portion and the outer lateral pad portion are applied to the surface from both sides in the foot width direction.

  In the insole pad for shoes having the structure according to this aspect, four swelled pad portions are provided in a substantially independent state, and a thin wall portion is provided between each pad portion and the pad portion. Can be bent. Therefore, it is possible to satisfactorily follow the changes in the dynamic shape of the soles during walking, and the walking support is made effective, and it is also possible to cope with irregular shapes on the bottom surface such as high heels.

  In addition, the lateral arch at the approximate tip of each metatarsal bone and the lateral arch at the tarsal bone are assisted by the front and back bottom pads, so that the therapeutic effect on health is sufficient in addition to the support effect of walking. Is expected. I think it is important to support these two lateral arches in terms of foot shock absorption and walking function. For example, “Basic knowledge of good shoes (revised 11th edition)” published by the Japan Shoe Research Institute This is because it is clearly pointed out in technical documents related to the present invention such as Japanese Patent No. 3049443 (Patent Document 4).

  That is, it can be said that one of the major features of the present invention is that these two lateral arches can be supported substantially independently. As a result, even when walking with shoes with special shapes such as high heels, each lateral arch is supported at each bottom pad part while advantageously following and deforming to the dynamic changes in the sole shape and the internal shape of the shoe. It will be assisted and excellent walking support can be realized.

  Moreover, since the medial lateral pad portion and the lateral lateral pad portion are applied to both sides of the shin side metatarsal bone and the heel side metatarsal bone, It will be supported by each lateral pad part in a wide range in the length direction, for example, concentrated load only on protruding parts such as shin side midfoot point (mt.t) and heel side midfoot point (mt.f) Is suppressed. Therefore, not only healthy people but also users of hallux valgus are alleviated from the pain and fatigue caused by the fact that the protruding part of the foot is pressed down strongly, and effective support force is applied to each metatarsal bone. It is conveyed stably.

  In addition, the foot is thickened up and down by the action of effective support (pressing force) from both sides in the foot width direction by the inner and outer lateral pad portions by holding the two lateral arches by the front and rear bottom pad portions, that is, by the effective arch The instep height of the metatarsal is increased. This is important not only for foot health but also for shoe fitting. The lid is not only held from both sides in the foot width direction by the inner and outer side pad parts, but also by being held from both the upper and lower sides by the upper member of the shoe that supports the upper etc. and the front and rear bottom pad parts. This is because the entire shoe is stably held. In addition, the pad portion formed by the thin wall portion is curved between the pad portions, so that the pad portion can be displaced or deformed according to the shape of the foot or the shoe, and the foot is further stabilized. And is held. This is the reason why the shoe fitting function is effectively demonstrated. In the insole pad for shoes according to this aspect, such an effect is that the two lateral arches are supported by the front and rear bottom pad portions, and the shin , 腓, can be achieved for the first time by applying the inner and outer lateral pad parts to both sides of the metatarsal bones from both sides in the foot width direction, and further enabling the bending between each pad part and the pad part It has one big technical feature.

(Aspect 2 of the present invention)
A feature of aspect 2 of the present invention is that, in the insole pad for shoes according to aspect 1 of the present invention, the front bottom pad portion is the foremost end edge portion. Five toes protrude from the bottom pad portion toward the front, and the five toes are placed directly on the insole of the shoe.

  In the insole pad having the structure according to the present aspect, the tip portion of the shoe in which the toes are accommodated is not narrowed by the insole, so that the toes are not unnecessarily compressed. In addition, since the toes are directly placed on the insole of the shoe, the force accompanying the kicking out action of the toes is efficiently transmitted to the insole during walking, and walking is made more advantageous, The feeling of wearing shoes can also be kept good.

(Aspect 3 of the present invention)
A feature of aspect 3 of the present invention is that in the insole pad for shoes according to the aspect 1 or 2 of the present invention, the rear bottom pad part is the rearmost edge part, and at the time of use, A heel protrudes rearward from the rear bottom pad portion so that the heel is placed directly on the insole of the shoe.

  In the insole pad structured according to this aspect, the depth dimension at the rear end portion of the shoe in which the heel is accommodated is not reduced by the insole. Therefore, the state where the heel is caught on the opening edge of the rear end of the shoe can be skillfully maintained, and the removal of the shoe may become a problem due to wearing the insole. Absent.

(Aspect 4 of the present invention)
The aspect 4 of the present invention is characterized in that, in the insole pad for shoes according to any one of the first to third aspects of the present invention, the front bottom pad portion has a protrusion height that is largest at a substantially central portion. Further, it has a substantially dome shape and is positioned below the connecting portion of each metatarsal bone with the ribs when used.

  In the insole pad structured according to this aspect, the connecting portion of each metatarsal bone with the rib is stably supported by the anterior bottom pad portion. The arch is assisted more effectively.

(Aspect 5 of the present invention)
A feature of aspect 5 of the present invention is that, in the insole pad for shoes according to any one of aspects 1 to 4 of the present invention, the rear bottom pad portion has a front-rear length dimension as compared to a left-right width dimension. In the use, the arch is positioned over substantially the entire arch, and the inner portion with the arch is made higher than the outer portion.

  In the insole pad structured according to this aspect, the posterior bottom pad portion supports the transverse arch in the tarsal bone over a wide range in the longitudinal direction. Further, based on the fact that the inner portion with the arch is raised higher than the outer portion, the rear bottom pad portion is more stably applied to the arch, and eventually to the lateral arch of the tarsal bone. Therefore, the said horizontal arch will be more effectively assisted by the back pad part, and the further improvement of walking support can be aimed at.

(Aspect 6 of the present invention)
A feature of aspect 6 of the present invention is that in the insole pad for shoes according to any one of aspects 1 to 5 of the present invention, the front edge of the inner lateral pad part is It is designed to be positioned rearward of the side midfoot point, and the front edge of the outer lateral pad portion is positioned rearward of the heel side midfoot point during use. There is in being.

  In the insole pad having the structure according to the present aspect, the inner and outer lateral points of the shin side middle foot point and the heel side middle foot point, which are the most prominent portions in the foot width direction, which are particularly noticeable in hallux valgus, etc. It is avoided that the pad portion is pressed. Therefore, even a healthy person and a user of hallux valgus can suppress pain caused by pressing the midfoot point with the lateral pad portion, and as a result, more comfortable walking Is realized.

(Aspect 7 of the present invention)
A feature of aspect 7 of the present invention is that in the insole pad for shoes according to any one of aspects 1 to 5 of the present invention, the inner and outer lateral pad portions are respectively located on the shin side and the heel side. It is to be applied over almost the entire length of the foot bone.

  In the insole pad structured according to this aspect, the lateral pad portion is applied to each metatarsal bone over a wider range, and the concentration of the load on each metatarsal bone is further advantageously suppressed.

(Aspect 8 of the present invention)
A feature of aspect 8 of the present invention is that, in the insole pad for shoes according to any one of aspects 1 to 7 of the present invention, one of the surfaces is a flat surface and the other surface is The front bottom pad portion, the rear bottom pad portion, the inner lateral pad portion, and the outer lateral pad portion are formed so as to protrude.

  In the insole pad having the structure according to this aspect, for example, by placing the flat surface on the insole and placing it, each pad part is directly applied to the foot and is stably attached to the insole. It is supported. In addition, for example, by placing the surface from which each pad portion protrudes on the insole and placing it, each pad portion is applied to the foot through a flat surface, and the pressing force exerted on the foot by the pad is adjusted. You can do it. That is, according to this aspect, it is possible to appropriately select an aspect in which the pad portion is directly or indirectly applied to the foot according to use conditions, manufacturability, and the like.

(Aspect 9 of the present invention)
A feature of aspect 9 of the present invention is that in the insole pad for shoes according to any one of the above aspects 1 to 8 of the present invention, the shoe is placed on the surface that is superimposed on the insole of the shoe in use. The fixing means for fixedly positioning with respect to the inner surface of this is provided.

  In the insole pad having the structure according to this aspect, each pad portion is stably applied according to the intended position of the foot, based on the fact that the wearing state is stable, so that walking support and fitting can be performed. Further improvements can be achieved. In addition, it does not specifically limit as a fixing means, For example, the well-known fixing means which adheres an insole pad to an insole etc. other than an adhesive tape, an adhesive agent, etc. is employ | adopted.

(The present invention relating to shoes)
A feature of the present invention relating to shoes resides in a shoe in which an insole pad for shoes according to any one of the first to ninth aspects of the present invention is attached.

  In such a shoe according to the present invention, depending on the internal shape of the shoe, the insole pad for the shoe is attached so that the space between each pad portion is curved. The pad can be easily deformed. Thereby, each pad portion is advantageously arranged at a target position. In addition, the two lateral arches and the tarsal bones described above are independently assisted at each pad portion, and they are also advantageously assisted in the dynamic change of the sole shape and the internal shape of the shoe. Has great technical features.

  Therefore, in the shoes having the structure according to the present invention, any of the effects of the insole having the structure according to the present invention as described above can be effectively exhibited, corresponding to the static sole shape. The superior auxiliary function of the arch structure and the fitting function of the shoe can be achieved to the extent that it cannot be achieved at all with the shoe of the conventional structure in which the insole of the shape is merely disposed.

  As is apparent from the above description, the insole pad for a shoe structured according to the present invention has a characteristic configuration in which four pad portions are provided in a substantially independent state. Two lateral arches are assisted by the front and rear bottom pad portions, and the shin, heel, and both metatarsals are supported from both sides in the foot width direction by the inner and outer lateral pad portions. In addition, the thin portion can be bent between each pad portion and the pad portion. As a result, during walking, each pad part is displaced or deformed so as to follow the dynamic changes of shoes and feet, and two lateral arches and metatarsals which are important parts for walking support are formed. Effectively assisted. Therefore, shoe fitting and walking support can be advantageously realized.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described. First, the insole 10 as one Embodiment of this invention is shown by FIGS. By placing the insole 10 on the midsole 14 of the high heel 12 as a shoe (see FIG. 6 and the like), for example, the height of the shoe sole, the inner width of the shoe, and the like are appropriately adjusted. ing. Note that the insole 10 shown in FIG. 1 is for the right foot. The insole for the left foot has a bilaterally symmetric shape as if the insole 10 for the right foot is mirrored, and the description thereof is omitted.

  More specifically, the insole 10 has a thin plate shape. The material is not particularly limited. For example, synthetic resin materials such as ethylene vinyl acetate resin, elastomer resin, polyurethane resin, natural resin materials such as natural rubber, sponge materials such as cork materials and foamed resins, etc. Or it is employ | adopted as a composite material which those multiples combined suitably. That is, for the insole 10 of the present invention, various known materials that have been conventionally applied to insoles can be employed, and in particular, those having a certain degree of elasticity are suitably employed. Further, the insole 10 is a flexible one in addition to elasticity, and can be bent or bent.

  The insole 10 includes a main body sheet portion 16, a front bottom pad portion 18, a rear bottom pad portion 20, an inner lateral pad portion 22, and an outer lateral pad portion 24.

  The main body sheet portion 16 has a thin flat sheet shape. In particular, in the present embodiment, the planar shape is substantially rectangular or substantially elliptical, and side portions 26 and 26 projecting outward in the width direction are integrally formed on both sides in the width direction. ing. The shape, size, position, and the like of the side portion 26 are not particularly limited, but in the present embodiment, an intermediate portion of the main body sheet portion 16 in the front-rear direction (longitudinal direction corresponding to the up-down direction in FIG. 1). A substantially rectangular flat plate shape extending in the longitudinal direction from the rear to the rear (downward in FIG. 1) is exhibited. A front bottom pad portion 18 and a rear bottom pad portion 20 are fixedly provided on the front portion and the rear portion of the main body sheet portion 16.

  The front bottom pad portion 18 has a substantially disk shape, and the outer peripheral portion has a conical shape from one side in the thickness direction (bottom in FIGS. 2 and 3) to the other side (in FIGS. 2 and 3, top). The taper is gradually reduced in diameter. In other words, the front bottom pad portion 18 has a substantially circular dome shape in which the protruding height is maximized at the central portion.

  The rear bottom pad portion 20 has a substantially rectangular flat plate shape with a long front and rear length dimension larger than the left and right width dimension. In addition, the outer peripheral portion of the rear bottom pad portion 20 is gradually reduced in height from one side in the height direction (in FIGS. 2 and 3 and above) to the other side (in FIGS. 2 and 3 and down). Thereby, the height dimension of the center part of the back bottom pad part 20 is made larger than the height dimension of the outer peripheral part. The slope of the outer peripheral portion is substantially the same as the slope of the outer peripheral portion of the front bottom pad portion 18. Further, the protruding height at the center portion of the rear bottom pad portion 20 is substantially the same as that of the center portion of the front bottom pad portion 18.

  In particular, in the present embodiment, the front bottom pad portion 18 and the rear bottom pad portion 20 are integrally formed at one place on the circumference by a valley-shaped connecting portion that linearly extends in the width direction (left-right direction in FIG. 1). It is connected. That is, the front and rear bottom pad portions 18 and 20 are integrally formed, and as a whole, have a flat and broad, substantially square shape.

  Further, the front bottom pad portion 18 and the rear bottom pad portion 20 are integrally connected to each other by a valley-shaped connecting portion (see FIG. 2), so that the space between the front bottom pad portion 18 and the rear bottom pad portion 20 is obtained. However, it is comprised as the 1st thin part 28 thinned over the full length. The first thin portion 28 is easily bent or curved along the valley line.

  Further, the front bottom pad portion 18 is superimposed on the front (upper in FIG. 1) portion of the main body sheet portion 16. Further, the rear bottom pad portion 20 is superposed on the rear portion (lower in FIG. 1) of the main body sheet portion 16 positioned between the pair of side portions 26 and 26. Then, the surface superimposed on the main body sheet portion 16 of the front and back bottom pad portions 18 and 20 and the surface superimposed on the front and rear bottom pad portions 18 and 20 of the main body sheet portion 16 are mutually bonded with an adhesive or the like. It is fixed. Further, an intermediate portion of the main body sheet portion 16 to which the first thin portion 28 is fixed is positioned forward of the front end portion of the side portion 26 and is integrated with the curvature of the first thin portion 28. It is designed to be curved.

  Further, the inner side pad portion 22 is fixed to one (left in FIG. 1) side portion 26a, and the outer side pad portion 24 is provided to the other side portion 26b (right in FIG. 1). Is fixed. These inner and outer lateral pad portions 22 and 24 each have a rectangular shape that is substantially narrower than the bottom pad portions 18 and 20 and extends substantially in the front-rear direction (vertical direction in FIG. 1). Then, one side (the lower side in FIG. 4) of each of the lateral pad portions 22 and 24 is overlapped over substantially the entire side portion 26 of the main body sheet portion 16 and fixed with an adhesive or the like.

  As a result, the inner lateral pad portion 22 and the outer lateral pad portion 24 are positioned apart in the width direction with the front bottom pad portion 18 and the rear bottom pad portion 20 interposed therebetween. Further, the outer peripheral portions of the horizontal pad portions 22 and 24 excluding the surfaces facing the front and rear bottom pad portions 18 and 20 are directed from one side (upper side in FIG. 4) to the other side (lower side in FIG. 4). The height dimension is gradually reduced. Further, the thickness dimension (projection height) of the inner lateral pad portion 22 and the outer lateral pad portion 24 is made substantially the same as that of the front bottom pad portion 18 and the rear bottom pad portion 20.

  Further, the inner side pad portion 22 and the front and rear bottom pad portions 18 and 20 are connected by a thin main body sheet portion 16. As a result, the second thin-walled portion 30 that can be bent is formed so that the inner side (left side in FIG. 1) of the front and rear bottom pad portions 18 and 20 extends substantially in the front-rear direction. Further, the outer lateral pad portion 24 and the front and rear bottom pad portions 18 and 20 are connected by a thin main body sheet portion 16. Thus, the third thin-walled portion 32 that can be bent is formed so that the outer sides (the right side in FIG. 1) of the front and rear bottom pad portions 18 and 20 extend substantially in the front-rear direction.

  For example, as shown in FIG. 5, the second thin portion 30 and the third thin portion 32 are curved or curved so as to form a valley shape on the protruding side surfaces of the horizontal pad portions 22 and 24. By being bent, each lateral pad portion 22, 24 is displaced so as to rise upward from the arrangement surface of the front and rear bottom pad portions 18, 20.

  As is clear from the above description, the main body sheet portion 16 and the side portions 26a and 26b have one surface (the lower surface in FIGS. 2 to 5) as a flat surface 34, while the other surface. Front and rear bottom pad portions 18 and 20 and inner and outer lateral pad portions 22 and 24 are overlapped and fixed to (the upper surface in FIGS. 2 to 5).

  The insole 10 having such a structure is attached to the high heel 12 as shown in FIGS. The high heel 12 is a well-known one, and has a heel 36 at a rear end portion on which the heel is placed, and an insole 14 which is inclined so as to gradually increase from the front where the toes of the foot are placed to the rear where the heel is placed. It has. The bottom bottom 38 is overlapped and fixed to the lower surface of the midsole 14. Further, an upper 40 that covers the toes, the upper, the heel and the like over the entire circumference is provided so as to rise from the outer peripheral edge of the insole 14 or the outsole 38. A housing region 42 into which a foot is inserted is formed in a portion surrounded by the insole 14 and the upper 40.

  The above-described insole 10 is inserted into the high heel 12 so that the front bottom pad 18 is directed to the front of the high heel 12 by being inserted into the accommodation region 42 from the opening of the upper 40. Under such a mounted state, the easily deformable first thin portion 28 is curved in a valley shape, so that the lower surface (flat surface 34) of the main body sheet portion 16 is aligned with the shape of the curved insole 14. It is positioned by being superimposed on the surface of the insole 14.

  Further, the second thin portion 30 is curved in a valley shape substantially corresponding to the shape of the upper 40 that covers the inside of the instep, and the flat surface 34 of the side portion 26 a is substantially overlapped with the inner surface of the upper 40. It is arranged in this way. Further, the third thin portion 32 is curved in a valley shape substantially corresponding to the shape of the upper 40 covering the outer side of the foot, and the flat surface 34 of the side portion 26b is substantially overlapped with the inner surface of the upper 40. It is arranged in this way.

  Accordingly, the front and rear bottom pad portions 18 and 20 and the inner and outer lateral pad portions 22 and 24 are supported by the inner surface of the shoe formed by the insole 14 and the upper 40, and project from the inner surface of the shoe toward the accommodation region 42. It has been.

  In the present embodiment, the shape of the insole 10 is maintained and superposed on the inner surface of the high heel 12 using the flexibility and elasticity of the first, second, and third thin portions 28, 30, and 32. It is positioned and mounted. However, if necessary, the flat surface 34 may be positioned on the inner surface of the shoe by being fixed to the inner surface of the high heel 12 using a fixing means such as an adhesive or an adhesive tape. .

  In the high heel 12 to which the insole 10 is mounted in this manner, when the foot 44 is put in the accommodation region 42, the front metatarsal arch 48 as a lateral arch at the substantially distal end portion of each metatarsal 46. Is supported by the front bottom pad portion 18. That is, the front bottom pad portion 18 is positioned below the substantially distal end portion of each metatarsal 46, and the front metatarsal arch 48 is placed on the front bottom pad portion 18. It can be positioned. As a result, the anterior metatarsal arch 48 is supported from below by the anterior bottom pad portion 18 so that the front metatarsal arch 48 has the correct arch shape, so that the lateral arch of the foot can be kept effective.

  Further, a transverse arch 56 as a transverse arch in the three wedge-shaped bones 52 and the cubic bones 54 constituting a part of the tarsal bone 50 is assisted by the rear bottom pad portion 20. That is, the rear bottom pad portion 20 is positioned below the substantially distal end portions of the wedge bone 52 and the cubic bone 54 so as to extend from the rear end portion of each metatarsal bone 46. The transverse arch 56 is positioned so as to rest on the part 20. As a result, the lateral arch of the foot can be effectively maintained by being supported from below by the rear bottom pad portion 20 so that the transverse arch 56 has a correct arch shape.

  The arch shapes of the front metatarsal arch 48 and the transverse arch 56 are held by the front and rear bottom pub portions 18 and 20, so that the original function of the foot can be effectively exhibited, and shock absorption and weight Movement and the like will be performed normally, which can contribute to foot health. In addition, since the arch shapes of the two arches 48 and 56 are positively held, the unhealthy foot spreading in the horizontal direction can be sufficiently secured. As a result, the foot 44 inserted into the shoe storage area 42 can be held by the upper part of the foot 44 so as to be skillfully sandwiched from the upper and lower sides by the shoe midsole 14 and the upper 40. In this way, the foot is held not only in the foot width direction but also in the upper and lower height directions by the inner surface of the shoe so as to surround the entire circumference including the lower surface and the upper surface of the foot. It will be fitted to the foot, and while maintaining good foot health, excellent fitting to the shoe will be realized, for example, effectively suppressing uncomfortable fluttering in the foot shoe during walking, etc. Is possible.

  Further, the inner lateral pad portion 22 is applied to the side surface of the shin side metatarsal 46a from the middle portion in the front-rear direction to the rear side. The lateral lateral pad portion 24 is also applied to the side surface of the metatarsal bone 46b on the heel side from the intermediate portion in the front-rear direction to the rear. That is, when the foot 44 is inserted into the accommodation area 42, the front edge (upper in FIG. 7) of the inner lateral pad portion 22 is substantially rearward (in FIG. 7) from the shin side midfoot point 58. The front edge of the outer lateral pad portion 24 is positioned substantially rearward of the heel-side middle foot point 60.

  As a result, both sides of the foot are supported by the inner and outer lateral pad portions 22 and 24, and the arch shapes of the anterior metatarsal arch 48 and the transverse arch 56 described above can be more advantageously maintained. In addition, because of the structure of the shoe, there is a gap between the foot 44 and the shoe inner surface. Since the lateral pad portions 22 and 24 are filled, the fitting to the shoe inner surface of the foot can be further improved. As a result, the feeling of wearing the shoes is greatly improved, and unnecessary movement of the foot in the front-rear direction in the shoes during walking is effectively suppressed.

  In particular, in the present embodiment, the front bottom pad portion 18 is formed on the foremost end edge portion of the insole 10. As a result, when the foot 44 is put into the accommodation area 42, the five toes 62 are protruded from the tip edge portion of the front bottom pad portion 18, and the five toes 62 become the insole 14. It is designed to be placed directly on.

  Further, the rear bottom pad portion 20 is the rearmost edge portion of the insole 10. As a result, when the foot 44 is put in the accommodation area 42, the heel 64 is projected from the rear edge of the rear bottom pad portion 20 toward the rear (right in FIG. 6), and the heel 64 is in the middle. It is placed directly on the bottom 14.

  Further, as described above, the front bottom pad portion 18 is positioned below (in FIG. 6, below) the connection portion between each metatarsal bone 46 and each rib 66 when the foot 44 is inserted into the accommodation region 42. It is supposed to be squeezed. Further, the rear bottom pad portion 20 is positioned over substantially the entire arch 64 when the foot 44 is put in the accommodation area 42 as described above. Furthermore, while the center part of the back bottom pad part 20 is made to oppose the inner part of the arch 68 in the foot height direction (up and down in FIG. 6), the outer peripheral part of the back bottom pad part 20 is The outer part of the arch 68 can be positioned opposite to the foot height direction.

  Therefore, in the insole 10 having the structure as described above, the height dimension (so-called shoe sole height dimension) and the width dimension (so-called shoe inner width) of the accommodation region 42 are attached to the high heel 12. Dimension) can be adjusted appropriately. In addition, the insole 10 can be used as an insole that exhibits specific functions and effects when used by being formed of a material having specific functions such as moisture absorption performance, deodorization performance, and buffer performance.

  In the present embodiment, the front metatarsal arch 48 and the transverse arch 56 are independently assisted by the front bottom pad portion 20 and the rear bottom pad portion 20, respectively. The support effect and the therapeutic effect on health can be advantageously exhibited.

  Further, the inner lateral pad portion 22 and the outer lateral pad portion 24 extending in the front-rear direction are applied to both side surfaces of the shin side metatarsals 46a and the heel side metatarsals 46b from both sides in the foot width direction. 44 is stably supported inside the shoe. Moreover, since the metatarsal bone 46 is prevented from being compressed locally, it is possible to suppress the occurrence of meat stabs, heels and the like on the foot 44, and the protruding portion of the foot of the hallux valgus, fish eyes, etc. It is avoided to hold down strongly.

  Further, there is a space between the front bottom pad portion 18 and the rear bottom pad portion 20, between the front and rear bottom pad portions 18 and 20 and the inner lateral pad portion 22, and between the front and rear bottom pad portions 18 and 20 and the outer lateral pad portion 24. Each of the thin portions 28, 30, 32 can be bent. Accordingly, by bending each thin portion 28, 30, 32, the mounting angle with respect to the middle bottom 14 of the front bottom pad portion 18 and the rear bottom pad portion 20, and the upper 40 of the inner lateral pad portion 22 and the outer lateral pad portion 24. The pad portions 18, 20, 22, and 24 are stably supported even on a specially shaped shoe such as the high heel 12 of the present embodiment by appropriately adjusting the mounting angle with respect to. In addition, it is possible to advantageously cope with different foot shapes for each individual.

  Furthermore, the inner lateral pad portion 22 and the outer lateral pad portion 24 are supported by the upper 40 and the like based on the elasticity of the second thin portion 30 and the third thin portion 32. It is avoided that the opening portion of the upper 40 is forcibly pushed out by the lateral pad portions 22 and 24 or the inner width dimension is increased more than necessary. Therefore, the fit feeling of the shoes is improved, and problems such as removal of shoes during walking and running and slipping out of the bag are effectively prevented.

  Furthermore, when the shape of the foot 44 and the internal shape of the high heel 12 are dynamically changed during walking or the like, each pad portion 18, 20, 22, 24 advantageously follows due to the curvature between the pad portions. As a result, the support function of the foot 44 can continue to be exhibited.

  In the present embodiment, in use, the five toes 62 are projected forward from the front bottom pad portion 18 and placed directly on the insole 14, and 64 protrudes rearward from the rear bottom pad portion 20 and is placed directly on the midsole 14. As a result, the outside of the heel 64 can be stably landed through the insole 14 and each toe 62 can be kicked out strongly, so that the normal walking support referred to as so-called tilt walking or the like is supported. Can advantageously contribute. In the tilting walk, first, the outer side of the heel 64 of the foot 44 is landed, and then the base of the little finger (the small ball) and the width of the thumb base (the base ball or the ball portion) are landed in this order. The second and third toes 62 refer to a method of kicking out while bending the joint of the toes 62 (the middle foot phalanx joint).
