Description

[Technical field]

[0001] The present invention relates to a foot mat and an insole that can respond to an individual's foot size and foot problems. [Background technology]

[0002] It is said that by using an insole with a front part at a position corresponding to an individual's foot size or foot trouble, and walking with the toe between the toes sandwiching the front part, it is possible to improve the troubles of disorders such as Morton's disease, hallux valgus, little toe varus, bowed toes, floating toes, etc. For example, it is said that improvement is possible by walking with the front part at the toe between the second and third toes or the toe between the third and fourth toes for Morton's disease, the toe between the first and second toes for hallux valgus, and the toe between the fourth and fifth toes for little toe varus.

[0003] It is said that one of the causes of the injury is wearing tight shoes. On the other hand, wearing shoes that are too big makes the feet slip in the shoes and move back and forth and side to side, which can cause fatigue and lead to ankle pain, back pain, knee pain, stiff shoulders, floating toes, etc. By using insoles correctly that have a front part and prevent the feet from slipping and moving in the shoes, pressure can be applied evenly over the entire sole of the foot, reducing the burden on the body such as the sole, ankle, knee, hips, and back, and reducing fatigue and pain.

[0004] Patent Document 1 describes the configuration of an insole that can stably transmit the force of the toes to the sole of the shoe, while also increasing the strength of the toes, and is easy to wear when placed in the shoe. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6617308 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the insole described in Patent Document 1 has a problem that the front surface is limited to the crotch between the first and second toes, and the movement of the front surface is limited to the front-rear direction, making it difficult to adapt to the foot problems and disorders of each person. Also, it is difficult to set the front surface at an optimal position according to the foot length and foot width according to the growth of each person. Furthermore, for people with foot disorders, the position of the crotch may move not only in the front-rear direction but also in the width direction as the foot grows, making it difficult to set the front surface at an optimal crotch position.

[0007] The present invention aims to solve the above problems and realize a foot mat, insole, and shoe that can attach a front part to a position that corresponds to the foot troubles of as many people as possible, differences in foot length and width size, differences in toe length and thickness due to individual differences, and changes due to growth. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a foot mat that is placed on the sole of the foot when walking, etc., and is characterized by having a plurality of front part attachment holes for attaching a front part in the tip area, which is the area within the range from the location of each of the five toes to the tip of the toes on the toe side of the foot mat.

[0009] This configuration makes it possible to realize a foot mat that can be attached to a position that corresponds to the foot troubles of as many people as possible, differences in foot length and width size, toe length and thickness due to individual differences, or changes due to growth. A foot mat is an insole that is made by attaching one or more front parts to any front part attachment hole provided in the foot mat. For example, by providing a front part in the area where the crotch between the third and fourth toes is located and walking or jogging, it is expected that Morton's disease will improve, by providing a front part in the area where the crotch between the first and second toes is located and walking, it is expected that hallux valgus will improve, and by providing a front part in the area where the crotch between the fourth and fifth toes is located and walking, it is expected that little toe varus will improve. In addition, by providing a front part in the area where the crotch between the second and third toes is located, it is possible to strengthen muscles.

[0010] Also, some people say that children grow quickly and soon become unable to wear shoes that are adjusted to their feet. In response to this, by purchasing shoes that are a little larger than they will be in a year or two, and inserting insoles that fit these shoes and gradually shifting the position of the front part toward the tip as the child's feet grow, the child can continue to wear the purchased shoes for a long period of time.

[0011] Furthermore, even adults with small feet can easily wear shoes that prioritize design and are optimally suited to them by purchasing larger shoes that prioritize design, storing a foot mat that matches the purchased shoes, and adjusting the position of the front part so that an appropriate gap is provided between the tips of the toes and the tip of the shoe.

[0012] Here, the region where the toe gap between the first and second toes is located, the region where the toe gap between the second and third toes is located, the region where the toe gap between the third and fourth toes is located, or the region where the toe gap between the fourth and fifth toes is located does not simply refer to the position of each toe gap on a person's foot, but refers to the surrounding region including the position of each toe gap of a standard person. In this way, by making the region a little wider, it is possible to accommodate the difference in toe gap position due to the difference in foot length and width size. In this case, each region may be set separately for an adult standard and a child standard.

[0013] The front part mounting hole is a through hole to which the front part can be mounted. The front part is made of a columnar member, and can be mounted from the back side of the sole mat using a bolt or a press-in member by using the front part mounting hole. By positioning this front part at each crotch and pinching it between the toes, the toes and the entire sole of the foot can be exerted with force. The front part may be cylindrical, rectangular, hexagonal, triangular, or elliptical.

[0014] The foot mat may be configured such that the plurality of front mounting holes are arranged in a front region of the foot mat, which is a region ranging from the tread portion of the sole to the tip of the toes.

[0015] With this configuration, when a person with a small foot wears a large shoe, the location where the front part is attached can be expanded to the location on the foot mat where the foot is placed, further improving the degree of freedom, and it is possible to realize a foot mat that can accommodate as many people's foot problems as possible, differences in foot length and width due to individual differences, differences in toe length and thickness, and changes due to growth. For example, improvements can be expected for hallux valgus, little toe varus, floating toes, flat feet, high arches, calluses on the backs of the toes, ingrown nails, calluses on the soles of the feet, etc., because the front part can be placed in an appropriate position.

[0016] It is also known that the arrangement of the first toe through the fifth toe varies from person to person. For example, there is the Egyptian type, in which the first toe is the longest and the second toe through the fifth toe are shorter, the Greek type, in which the second toe is the longest, the Roman type, in which the first toe through the fifth toe are almost equal in length, the German type, in which the first toe is exceptionally long and the second toe through the fifth toe are almost the same length, and the Celtic type, in which the second toe is the longest, the first toe and the third toe are almost the same length, followed by the fourth toe and fifth toe, which are shorter. In other words, since the position of the toes varies depending on the characteristics of each foot type (however, the positions of the above five toes and the position of the toes are not necessarily correlated), it is desirable to walk with the front part upright in a position that suits each foot type, and by configuring the multiple front part mounting holes to be located in the front area, which is the area from the toes between the five toes to the plantar part of the foot, the freedom of positioning of the front part can be improved.

[0017] The foot mat may be configured such that the plurality of front base mounting holes are through holes that are evenly arranged in a staggered pattern.

[0018] With this configuration, the number of holes can be increased efficiently by staggering the front part mounting holes, and the strength of the foot mat can be maintained even if many holes are made through the front part. In addition, by arranging the holes evenly, the front part mounting holes can be arranged in a balanced manner. Furthermore, by making the holes through the front part, the front part can be easily attached.

[0019] The sole mat may be configured so that a ventilation hole for ventilation is provided on the heel side of the front region.

[0020] This structure allows the sole mat to have good ventilation. Also, if the front mounting hole is made larger than the ventilation hole, the sole mat can have particularly good ventilation. Also, the ventilation hole does not necessarily have to be a through hole, and the surface may be covered with a meshed cloth or the like.

[0021] The sole mat may be in the form of a flat sheet, with the left and right foot mats having the same shape.

[0022] With this configuration, the left foot pad can be turned inside out to become the right foot pad, and the right foot pad can be turned inside out to become the left foot pad, improving production efficiency and usability for the user.

[0023] The sole mat may be configured to have a thick sole with at least a high heel portion.

[0024] This configuration allows the center of gravity of the body to shift forward, allowing the user to assume a posture in which they can put pressure on their toes, contributing to improved health.

[0025] The sole mat may be configured so that positions according to foot sizes are indicated in the tip area.

[0026] With this configuration, for example, a standard sole mat for children can be prepared and cut according to the markings according to the foot size to obtain the desired size, improving production efficiency and usability for users. Also, by using a sole mat that matches the size of a shoe larger than the foot size and positioning the front part of the sole mat closer to the heel than usual, contact between the toes and the inner tip of the shoe can be avoided, preventing damage to the toes, and allowing the wearer to wear larger shoes that prioritize design.

[0027] The sole mat may be configured such that a region within a range from where the crotch of the toes is located to the tip side is cut off.

[0028] This structure allows the toes to bend when walking, so that on steep uphill slopes the toes grip the edge of the cut foot mat, allowing the toes to exert more force, which contributes to health promotion. Also, on downhill slopes, the lack of a foot mat under the toes allows the toes to brace themselves more firmly, supporting the body and preventing slipping. This is expected to have a deterrent effect against toe fatigue, ankle pain, fractures, blood blisters, blisters, lower back pain, knee pain, and falls.

[0029] The sole mat may be configured so that the heel side is cut away from the area within the range where the tread portion is located.

[0030] This configuration allows the user to walk in a posture that allows the toes to be pressed firmly, which contributes to health promotion through strengthening and training the plantar muscles and dieting.

[0031] The sole mat may have a small projection attached to the front mounting hole where the pressure points on the sole of the foot are located.

[0032] With this configuration, the acupressure points are stimulated while walking or jogging, and physical problems can be expected to be relieved.

[0033] The insole may be characterized in that the front part made of a columnar member is attached to the above-mentioned sole mat by a bolt or a press-fit member.

[0034] This configuration allows the insole to be attached to a position that can accommodate the foot problems of as many people as possible, differences in foot length and width, and toe length and thickness due to individual differences, or changes due to growth. The columnar member may be any shape, such as a cylindrical or rectangular column shape.

[0035] The shoe may be characterized by containing an insole having the aforementioned front part.

[0036] This configuration allows the shoe to be equipped with an insole that can accommodate the foot problems of as many people as possible, differences in foot length and width, and differences in toe length and thickness due to individual differences, or changes due to growth. Effect of the Invention

[0037] The foot mat, insole, and shoes of the present invention can realize a foot mat, insole, and shoes that can attach the front part to a position that corresponds to the foot troubles of as many people as possible, differences in the length and width of the foot and the length and thickness of the toes due to individual differences, and changes due to growth. It is also expected to be effective in strengthening the muscles of the toes and sole and forming the arch of the foot. [Brief description of the drawings]

[0039] A foot mat according to a first embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a diagram for explaining the foot mat according to the first embodiment of the present invention, in which Fig. 1(a) shows a front view and Fig. 1(b) shows a side view.

[0040] The sole mat 10 in the first embodiment is placed on the sole of the foot when walking (walking, jogging, climbing, etc.), and may be used as an insole or placed on top of an insole, as described later. The sole mat 10 is a flat sheet made of synthetic resin and has a shape roughly resembling the sole of the foot, and has a plurality of front part attachment holes M for attaching a front part in a tip area 21 (see FIG. 1), which is an area within a range from the places 11-14 where the crotches of the five toes are located to the tip of the sole mat on the toe side. The shape of the front part attachment holes M is not particularly limited, and may be any shape such as a circle, a triangle, a rectangle, a hexagon, or an ellipse.

[0041] Here, the five toe spaces refer to the spaces between the first toe 1 and the second toe 2, the second toe 2 and the third toe 3, the third toe 3 and the fourth toe 4, and the fourth toe 4 and the fifth toe 5, as shown by the two-dot chain lines in Fig. 1(a). The toe crotch refers to the crotch between the first toe 1 and the second toe 2, the second toe 2 and the third toe 3, the third toe 3 and the fourth toe 4, and the fourth toe 4 and the fifth toe 5, i.e., the base of the toes.

[0042] The front part mounting holes M in the tip region 21 are provided in the length direction of the foot (direction from the heel to the toes) and the width direction of the foot (direction perpendicular to the length direction of the foot). This allows the front part to be attached to the front part mounting holes M that correspond to individual differences in the length direction of the foot, individual differences in the width direction of the foot, and individual differences and growth changes in the length and thickness of the toes, making it possible to create an insole.

[0043] Here, the front part is, for example, as shown in the front part 88 of FIG. 8, a cylindrical columnar member of 11 mmφ×20 mm, with an internal thread and can be attached from the back side of the sole mat 10 by a bolt 89 or a press-in member using the front part attachment hole. The front part 88 can be positioned at each crotch and sandwiched between the toes to allow the toes to exert force. For example, by attaching the front part 88 to the area 11 between the first toe 1 and the second toe 2 and sandwiching it between the first toe 1 and the second toe 2, a person with hallux valgus can walk easily, and by attaching the front part 88 to the area 14 between the fourth toe 4 and the fifth toe 5 and sandwiching it between the fourth toe 4 and the fifth toe 5, a person with little toe varus can walk easily. The size of the front part attachment hole M is preferably 3 mmφ to 6 mmφ, and most preferably about 5 mmφ.

[0044] In addition, in order to strengthen the muscles of each toe and increase the ability to brace oneself, it is expected to be effective to attach the front part 88 to the area 12 between the second toe 2 and the third toe 3 and walk with the foot sandwiched between the second toe 2 and the third toe 3, or to attach the front part 88 to the area 13 between the third toe 3 and the fourth toe 4 and walk with the foot sandwiched between the third toe 3 and the fourth toe 4.

[0045] Here, in Example 1, there are multiple front base mounting holes M in tip region 21, which is the area within the range from locations 11-14 where each of the five toes is located to the tip of the toes on the toe side of the sole mat, but the front base mounting holes M do not necessarily have to be provided over the entire surface of tip region 21, and may be provided in any area within tip region 21 that is required by each individual.

[0046] Also, it is not necessary to attach the front part to all of the locations 11-14 where the toes are located, but it is sufficient to attach it to the location that is necessary for each person. Conversely, the front part may be attached to one front part attachment hole M in the area where all the toes are located. Furthermore, the front part may be attached to multiple front part attachment holes M in the area where any of the toes are located.

[0047] In this way, the front part can be attached to the front part mounting hole M at any position and can also be freely removed, so the mounting position of the front part can be freely changed depending on the growth of the feet and the presence or absence of foot problems or disorders.

[0048] As described above, the sole mat 10 in the first embodiment has a flat sheet-like shape that is roughly the shape of a sole, so that the right foot mat in Fig. 1 can be turned over to become the left foot mat. In other words, the left foot mat and the right foot mat have a common shape. In addition, since the sole mat 10 is a flat sheet-like shape, it can be used by being placed in the sole of a shoe, and can also be used by being placed on top of an insole placed in the sole of a shoe.

[0049] In the first embodiment, the front edge is configured to be a cylindrical member having a diameter of 11 mm×20 mm, but this is not necessarily limited to this and can be modified as appropriate. For example, the front edge may be a rectangular prism that is long from front to back, a triangular prism, a hexagonal prism, or an elliptical prism. The front edge does not have to be a cylindrical member, and may be any shape such as a bellows shape. The front edge may be a cylindrical member having a diameter of 11 mm or less or a diameter of 11 mm or more, and may be a height of 20 mm or more or 20 mm or less.

[0050] In addition, in the first embodiment, the sole mat is in the form of a flat sheet, but this is not necessarily limited to this and can be modified as appropriate. For example, the shape may be such that it has a convex portion on the side or rear of the heel portion to fit the heel portion.

[0051] Thus, in Example 1, a foot mat is placed on the sole of the foot when walking, etc., and is characterized by having a plurality of front part attachment holes for attaching a front part in the tip area, which is the area within the range from the location of each of the five toes to the tip of the toes on the toe side of the foot mat.This makes it possible to realize a foot mat that can attach a front part in a position that corresponds to the foot problems of as many people as possible, individual differences in foot length and width size, and toe length and thickness, or changes due to growth. EXAMPLES

[0052] The second embodiment of the present invention is different from the first embodiment in that a plurality of front mounting holes are arranged in a front region of the foot mat, which is a region within a range from the tread portion of the sole to the tip of the toes. The second embodiment will be described with reference to Fig. 2. Fig. 2 is a diagram for explaining the foot mat in the second embodiment of the present invention, in which Fig. 2(a) shows a front view and Fig. 2(b) shows a side view.

[0053] The sole mat 20 in the second embodiment has a flat sheet shape that is roughly the shape of a sole of the foot. Although the sole mat 20 is shown in Fig. 2 as being for the right foot, it can be turned over to be for the left foot because it has a flat sheet shape, so that the user only needs to prepare two of the same mat, which is convenient and improves the efficiency of production.

[0054] In the second embodiment, a plurality of front mounting holes M are evenly arranged in the front region 22, which is the region in the range from the planting part of the sole of the foot to the tip of the toes. This improves the degree of freedom in the position to attach the front part, and it is possible to realize a foot mat in which the front part can be attached in a position that corresponds to the foot troubles of as many people as possible, differences in the length and width of the foot and the length and thickness of the toes due to individual differences, or changes due to growth. Here, the planting part refers to the region other than the tip region 21 in the front region 22 of the sole mat.

[0055] For example, as shown in Fig. 8, a front part 88 made of a cylindrical columnar member can be attached to any front part attachment hole M in the front region 22 from the back side of the sole mat 20 with a bolt 89 or a press-in member to form an insole, and the front part 88 can be positioned at any crotch and sandwiched between the toes to allow the toes to exert force. For example, by attaching the front part 88 to a location 11 between the first toe 1 and the second toe 2 and sandwiching it between the first toe 1 and the second toe 2, a person with hallux valgus or flat feet can walk easily, and by attaching the front part 88 to a location 14 between the fourth toe 4 and the fifth toe 5 and sandwiching it between the fourth toe 4 and the fifth toe 5, a person with little toe varus or sleeping toe can walk easily. Also, by attaching the front part 88 to the location 12 between the second toe 2 and the third toe 3 and sandwiching it between the second toe 2 and the third toe 3, people with floating toes or people with Morton's disease can walk easily, or by attaching the front part 88 to the location 13 between the third toe 3 and the fourth toe 4 and sandwiching it between the third toe 3 and the fourth toe 4, people with Morton's disease can walk easily. Also, by attaching the front part 88 to the location 14 between the fourth toe 4 and the fifth toe 5 and sandwiching it between the fourth toe 4 and the fifth toe 5, the force applied to the outside can be reduced, and people with sleeping toes on the fifth toe 5 can walk easily. Furthermore, it is expected to be effective in strengthening the muscles of each toe. Also, it is expected that by attaching the front part 88 or small protrusions to the positions that stimulate each acupoint, it can be expected to relieve insomnia and irritability.

[0056] It is also known that the arrangement of the first toe 1 to the fifth toe 5 varies from person to person. For example, the Egyptian type in which the first toe 1 is the longest and the second toe 2 to the fifth toe 5 are shorter, the Greek type in which the second toe 2 is the longest, the Roman type in which the first toe 1 to the fifth toe 5 are almost equal in length, the German type in which the first toe 1 is exceptionally long and the second toe 2 to the fifth toe 5 are almost the same length, and the Celtic type in which the second toe 2 is the longest, the first toe 1 and the third toe 3 are almost the same length, and the fourth toe 4 and the fifth toe 5 are short. In other words, since the locations 11 to 14 where the toes are located differ depending on each foot type, it is desirable to walk with the front part standing at a position that matches each foot type, and the configuration in which multiple front part mounting holes are widely arranged in the front region 22 can improve the freedom of the position to mount the front part.

[0057] Furthermore, by providing the front part mounting holes M in the area where the foot is located, it is possible to accommodate the foot sizes of, for example, junior high school and high school students, and to improve breathability.

[0058] In the second embodiment, ventilation holes H are further provided uniformly around the heel of the sole. The size of the front mounting hole M is preferably 1 mmφ to 15 mmφ, and most preferably about 5 mmφ. The size of the ventilation hole H is about 1 to 15 mmφ.

[0059] The front base mounting holes M may be through holes arranged in a staggered pattern and evenly. By arranging the front base mounting holes in a staggered pattern, the number of holes can be increased efficiently, and the strength of the sole mat can be maintained even if many holes are inserted. In addition, by arranging them evenly, the front base mounting holes can be arranged in a balanced manner. Furthermore, by making them through holes, the front base can be easily attached.

[0060] In the second embodiment, the front base mounting holes M are arranged in a staggered and uniform manner, but this is not necessarily limited to this and can be modified as appropriate. For example, they may be arranged randomly, or may be arranged linearly in the front-rear or width direction. The size of the ventilation hole H is not particularly limited. For example, the ventilation hole H may be a hole smaller than the front base mounting hole M, the ventilation hole H may be a hole of the same size as the front base mounting hole M, or the ventilation hole H may be a hole larger than the front base mounting hole M.

[0061] Thus, in Example 2, a number of the front part mounting holes are positioned in the front region, which is the area in the range from the plantar part of the sole of the foot to the tip of the toes, thereby improving the freedom of positioning to attach the front part, and making it possible to realize a foot mat in which the front part can be attached in a position that corresponds to the foot problems of as many people as possible, individual differences in foot length and width size, toe length and thickness, or changes due to growth. EXAMPLES

[0062] Example 3 of the present invention differs from Examples 1 and 2 in that it has at least a thick sole with a high heel. Example 3 will be described with reference to Fig. 3. Fig. 3 is a diagram for explaining the foot mat in Example 3 of the present invention, with Fig. 3(a) showing a front view and Fig. 3(b) showing a side view.

[0063] In the third embodiment, a thick sole 33' is attached to the heel part on the back side (opposite the direction in which the foot is positioned) of the sole mat 30. The thick sole 33' is attached to the heel part of the sole mat body 33 by adhesive. The thick sole 33' has a maximum height of about 10 mm. This allows the center of gravity of the body to shift forward, allowing the user to assume a posture in which the toes are pressed, which contributes to health promotion.

[0064] In the third embodiment, the thick sole 33' is attached to the heel of the sole mat body 33 by adhesion, and has a maximum height of about 10 mm, but this is not necessarily limited to this and can be modified as appropriate. For example, the thick sole may be attached not only to the heel but also from the tip of the toe side to the heel. In this case, the thick sole may be slightly lower on the toe side. The sole mat body 33 may also be an integrated thick sole, with a maximum height of 10 mm or more. It is sufficient to have a thick sole with at least a high heel.

[0065] Here, when the shoe has a thick sole with a high heel, problems such as blood flow problems, swelling, poor circulation, ingrown nails, calluses, corns, bowed toes, bunions, bunions, flat feet, floating toes, or high arches that tend to occur due to cramped toes can be prevented by attaching the front part to an appropriate position and providing a gap between the toes and the front surface of the shoe.

[0066] In this way, in the third embodiment, by providing a thick sole with a high heel, the center of gravity of the body is shifted forward, allowing the wearer to assume a posture in which the toes are pressed down, which contributes to health promotion. It is also expected to have an effect on hip-up beauty. EXAMPLES

[0067] Example 4 of the present invention is different from Examples 1 to 3 in that a position according to the foot size is displayed in the tip region. Example 4 will be described with reference to Fig. 4. Fig. 4 is a diagram for explaining a foot mat in Example 4 of the present invention, Fig. 4(a) is a front view, and Fig. 4(b) is a side view.

[0068] The sole mat 40 in the fourth embodiment has a flat sheet shape that is roughly the shape of a sole of the foot. Although the sole mat 40 is shown in Fig. 4 as being for the right foot, since the sole mat 40 has a flat sheet shape, it can be turned over to be for the left foot, so that the user can prepare and use two of the same mats, which is convenient and improves the efficiency of production.

[0069] A plurality of front part mounting holes M are evenly arranged from the tip region 21 where each of the five toes of the foot mat 40 is located to the region 22 where the plantar part of the sole is located. This improves the degree of freedom in the position where the front part is attached, and makes it possible to realize a foot mat that can accommodate as many people's foot problems as possible and differences in foot length and width due to individual differences or growth.

[0070] In the fourth embodiment, the tip of the area where the toes are located is printed to indicate the position according to the foot size. That is, the line 44 indicating the tip of the toes and the foot size 45 such as "23", "24", and "25" are printed on the surface of the sole mat. By cutting the sole mat 40 according to the line 44 indicating the tip of the displayed toes, it is possible to obtain a sole mat of the desired foot size, which reduces inventory and allows the user to easily obtain a sole mat of the desired foot size.

[0071] In this way, in Example 4, by displaying the position according to the foot size in the tip area, the desired size can be achieved by cutting along the marking according to the foot size, thereby improving production efficiency and usability for the user. EXAMPLES

[0072] Example 5 of the present invention differs from Examples 1 to 4 in that the area within the range from where the crotch of the toes is located to the tip side is cut. Example 5 will be described with reference to Fig. 5. Fig. 5 is a diagram for explaining the sole mat in Example 5 of the present invention, Fig. 5(a) is a front view, and Fig. 5(b) is a side view.

[0073] The sole mat 50 in the fifth embodiment has a flat sheet shape that is roughly the shape of a sole of the foot. Although the sole mat 50 is shown for the right foot in Fig. 5, since the sole mat 50 has a flat sheet shape, it can be turned over to be for the left foot, so that the user can prepare two of the same mats for use, which is convenient and improves the efficiency of production.

[0074] A plurality of front base attachment holes M are evenly arranged from the tip region 21 of the foot mat 50 to the front region 22, which is the region within the range where the plantar part of the sole is located. This improves the degree of freedom in the position to attach the front base, and makes it possible to realize a foot mat that can accommodate as many people's foot problems as possible and differences in foot length and width due to individual differences or growth.

[0075] In the fifth embodiment, the tip side 56 of the sole mat 50 is cut from the location where the toes are located. As a result, the toes are in an area without the sole mat 50, and the toes are in a position where they can be forced when walking. In particular, when climbing a mountain, the base of the toes can be easily climbed by grabbing the cut surface of the sole mat with the five toes to get a foothold, and when going downhill, the toes can be firmly supported by the pads of the five toes, making it easier to force the toes. This allows the ankles, feet, knees, and hips to be stable and allows for easier walking. In addition, if a sole mat smaller than the foot size is placed on the sole, the toes may protrude from the sole mat, but even in this case, the same effect as the configuration in which the tip side 56 is cut from the area within the range where the toes are located can be obtained.

[0076] In this way, in the fifth embodiment, the tip side 56 is cut from the location of the pads of the toes, so that the toes can be forced into a posture when walking, which contributes to health promotion. In addition, the ability to brace oneself is improved, and mountain climbing can be performed easily. EXAMPLES

[0077] Example 6 of the present invention differs from Examples 1 to 6 in that the heel side is cut from the area within the range where the footbed is located. Example 6 will be described with reference to Fig. 6. Fig. 6 is a diagram for explaining the sole mat in Example 6 of the present invention, Fig. 6(a) is a front view, and Fig. 6(b) is a side view.

[0078] The sole mat 60 in the sixth embodiment has a flat sheet shape that is roughly the shape of a sole of the foot. Although the sole mat 60 is shown for the right foot in Fig. 6, since the sole mat 60 has a flat sheet shape, it can be turned over to be for the left foot, so that the user can prepare and use two of the same mats, which is convenient and improves the efficiency of production.

[0079] A plurality of front part mounting holes M are evenly arranged from the tip part 21 of the foot mat 60 to the front part 22, which is the part where the plantar part of the sole is located. This improves the degree of freedom in the position where the front part is attached, and makes it possible to realize a foot mat that can accommodate as many people's foot problems as possible and differences in foot length and width due to individual differences or growth.

[0080] In the sixth embodiment, the heel side 67 is cut from the area where the foot is located. This leaves the heel without the sole mat 60, allowing the wearer to exert force on the toes and stretch the body.

[0081] In the sixth embodiment, the heel side 67 is cut from the area where the foot is located, but this is not necessarily limited to this and can be modified as appropriate. For example, the heel side 67 may be cut from the area where the foot is located, and the tip side 56 may be cut from the area where the toes are located. This allows the user to apply more force to the toes and stretch the body.

[0082] In this way, in the sixth embodiment, the heel side 67 is cut from the area within the range where the foot is located, so that the toes can be forced when walking, which contributes to health promotion. Also, since there is no sole mat in the heel area, more pressure is applied to the toes and soles, which is expected to strengthen the muscles of the toes and soles, improve posture, lift the hips, and have a diet effect. It is especially suitable for athletes and others who want to strengthen their legs and hips. EXAMPLES

[0083] Example 7 of the present invention differs from Examples 1 to 6 in that a small protrusion is attached to the front base attachment hole where the acupressure points on the sole are located. Example 7 will be described with reference to Fig. 7. Fig. 7 is a diagram for explaining the insole in Example 7 of the present invention, with Fig. 7(a) being a front view, Fig. 7(b) being a side view, and Fig. 7(c) being a side view of the small protrusion.

[0084] It is said that there are several dozen acupressure points on the sole and crotch. In the seventh embodiment, in order to appropriately stimulate the acupressure points suitable for each person, small protrusions 71 are attached to any front mounting holes M in the sole or crotch where the acupressure points are located in the front region 22 of the sole mat 70 by bolts 72 or press-fitting members. In this way, by focusing on the acupressure points necessary for each person and attaching the small protrusions 71, a custom-made sole massage can be achieved, and the acupressure points can be stimulated while walking or jogging, and physical problems can be expected to be relieved. The height of the small protrusions may be about 2 mm to 5 mm.

[0085] In this way, in Example 7, by attaching small protrusions to the front part mounting holes of the sole mat 70 where the acupressure points on the soles of the feet are located, the acupressure points can be stimulated while walking, jogging, etc., and physical problems can be expected to be relieved. EXAMPLES

[0086] Example 8 of the present invention differs from Examples 1 to 7 in that an insole is formed by attaching a front part made of a cylindrical columnar member to a sole mat with a bolt or a press-fit member. Example 8 will be described with reference to Fig. 8. Fig. 8 is a diagram for explaining the insole in Example 8 of the present invention, Fig. 8(a) is a front view, and Fig. 8(b) is a side view.

[0087] The insole 80 in Example 8 is formed by attaching a front part 88 made of a cylindrical columnar member to any of the sole mats 10 to 70 described above with a bolt 89 or a press-fit member to any front part mounting hole M in the front region 22, and positioning it at each crotch and holding it between the toes so that pressure can be applied to the toes. In Example 8, there are four front parts 88 so that the front part 88 is attached to a location 11 between the first toe 1 and the second toe 2 and sandwiched between the first toe 1 and the second toe 2, the front part 88 is attached to a location 14 between the fourth toe 4 and the fifth toe 5 and sandwiched between the fourth toe 4 and the fifth toe 5, the front part 88 is attached to a location 12 between the second toe 2 and the third toe 3 and sandwiched between the second toe 2 and the third toe 3, and the front part 88 is attached to a location 13 between the third toe 3 and the fourth toe 4 and sandwiched between the third toe 3 and the fourth toe 4, allowing walking with the front part 88 sandwiched between the third toe 3 and the fourth toe 4.

[0088] The front part 88 is made of a cylindrical columnar member with a female thread cut in the center, and can be attached from the underside of the foot mat (the side opposite to the direction in which the feet are positioned) with a bolt 89 or a press-in member. This allows the front part 88 to be attached in any position.

[0089] Here, in the eighth embodiment, the front part 88 is attached to all of the locations 11 between the first toe 1 and the second toe 2, 12 where the toe gap between the second toe 2 and the third toe 3 is located, 13 where the toe gap between the third toe 3 and the fourth toe 4 is located, and 14 where the toe gap between the fourth toe 4 and the fifth toe 5 is located, but it is not necessary to attach the front part 88 to all the locations where the toes are located, and it is sufficient for each person to attach the front part to one of the front part mounting holes M at the location required. Furthermore, the front part 88 may be attached to multiple front part mounting holes M at the locations where any of the toes are located.

[0090] In the eighth embodiment, the front base 88 made of a cylindrical columnar member is attached to any one of the sole mats 10 to 70, but this is not necessarily limited to this and can be modified as appropriate. For example, it may be a square prism, a hexagonal prism, a triangular prism, or an elliptical prism, or any other shape. The front base 88 may be attached by cutting a male thread in the front base 88 and attaching it with a nut, or it may be configured to cut a female thread in the front base attachment hole M of the sole mat and screw in a bolt. Furthermore, the front base may be a flexible, bendable press-in member made of synthetic resin.

[0091] A soft, cylindrical elastic sleeve (not shown) may be provided around the front part 88 to be gentle on the toes and toes. The elastic sleeve may be of any shape. When the front part 88 is attached to the front part mounting hole M, it may be attached with a bolt 89 or a press-fit member via a washer (not shown) to prevent it from coming loose.

[0092] In this way, in the eighth embodiment, the insole 90 is made by attaching the front part made of a columnar member to any one of the sole mats 10 to 70 with a bolt or a press-in member, thereby realizing an insole that can attach the front part at a position that corresponds to the foot troubles of as many people as possible, differences in foot length and width size due to individual differences, differences in toe length and thickness, and changes due to growth. This insole can be used by inserting it into shoes. EXAMPLES

[0093] Example 9 of the present invention differs from Examples 1 to 8 in that an insole support member is provided in the front part of the insole where the insole support member in Example 8 described above is not required. Example 9 will be described with reference to Fig. 9. Fig. 8 is a diagram for explaining the insole in Example 9 of the present invention.

[0094] The insole 90 in the ninth embodiment has a front part 88 attached to one of the sole mats 10 to 70, and further has an instep support member 91 attached to the end of the front part 88 on the opposite side to the sole mat. The instep support member 91 can be attached by a bolt 92 or a press-in member, utilizing the female thread of the front part. This makes it possible to realize an insole that can attach the front part to a position that corresponds to the foot problems of as many people as possible, differences in foot length and width size due to individual differences, differences in toe length and thickness, or changes due to growth.

[0095] Here, the upper support member 91, when housed in the insole of the shoe, makes the front part difficult to collapse by contacting the inner surface of the front part of the shoe and the inner surface of the upper part. In other words, when the insole 90 is housed in the insole of the shoe, the heel side area of ​​the upper support member 91 and the inner surface of the upper part of the shoe are in contact and held, so that the movement of the upper support member 91 toward the tip side of the shoe and the movement to the left and right can be more reliably suppressed, and the front part can be reliably held in a predetermined position between the insole body 93 and the upper support member 91.

[0096] The length of the instep support member 91 on the toe side may be short or long, and the length on the heel side may be short or long. The shape may be any shape, such as a substantially triangular, substantially rectangular, or substantially elliptical shape. Furthermore, the instep support member 91 is configured to be attached using the female thread of the front part with the bolt 92 or a press-in member, but this is not necessarily limited to this and can be modified as appropriate. For example, a longer bolt may be inserted into the front part from the instep support member 91 side, and a nut may be fastened on the back side of the insole body 93. EXAMPLES

[0097] The tenth embodiment of the present invention is different from the first to ninth embodiments in that the insole is accommodated in the shoe. This allows for the realization of shoes that can accommodate the foot troubles of as many people as possible, differences in foot length and width, toe length and thickness due to individual differences, and changes due to growth. There is no particular limit to the type of shoes, and the insole can be accommodated in any shoes, such as medical shoes, safety shoes, cooking shoes, sports shoes, hiking shoes, commuting shoes, and school shoes.

[0098] In other words, the insole 80 or 90 is placed in the sole of the shoe, and the shoe is provided with a front part at a position corresponding to the foot size or illness of each person. In this case, by providing the front part at a desired position on the flat sheet-like sole mat, the same sole mat can be used for both the right and left feet. [Industrial Applicability]

[0099] The foot mats, insoles, and shoes of the present invention can be widely used in the field of foot mats, insoles, and shoes that can address the foot problems of as many people as possible, differences in foot length and width and toe length and thickness due to individual differences, or changes due to growth.
