Claims 1 / 1 page 2 CN 121908968 A Footwear with Posture Correction Function Technical Field

[0001] The present invention relates to footwear such as sandals having a sole for placing a user's foot and an upper portion covering the user's foot, and more particularly to footwear with posture correction function.Background Art

[0002] Footwear such as sandals is generally constructed by providing a fixed strap or an upper part such as an eyelet on a flat sole shaped like the foot. Furthermore, sandals with various functions, such as protrusions on the sole that stimulate acupoints on the sole during walking, have also been developed.

[0003] Patent Document 1 discloses a type of footwear having a footrest, a forefoot, and an eyelet, wherein the footrest is formed by joining a first layer with a thin sole to a second layer without a thin sole. The thin sole of this first layer is missing at the little toe side relative to the forefoot and at the toe tip relative to the heel. According to this structure, when a user walks while wearing this footwear, the user's center of gravity can be corrected inwards, and if the user has bowlegs, the distance between the user's knees can be narrowed. Patent Document 1 also further discloses footwear in which the heel portion of the footrest is missing in an arc or straight shape, allowing the user to walk on tiptoe.

[0004] Furthermore, Patent Document 2 discloses a type of footwear that, in which a sole for placing a user's foot, an upper portion covering the instep, and an inner sole are arranged such that the sole of the foot is divided into a toe portion and a heel side near the arch, with the toe portion further divided into a thumb side (inner side) and a little finger side (outer side), and the little finger (outer side) portion roughly corresponding to the thin sole. Patent Document 2 also describes an example where the heel portion of the sole has a notch. Because of this notch, the footwear described in Patent Document 2 allows the user to walk on tiptoe, naturally exercising the muscles from the calves, inner thighs, to the buttocks.

[0005] Patent Document 1: Japanese Patent No. 7166035 Patent Document 2: Japanese Patent No. 7454299 Summary of the Invention Problem to be Solved by the Invention

[0006] When walking in shoes, striking the ground with the heel (heel strike) can be considered to have several advantages. First, by striking the ground with the heel and then bearing the impact of the ground with the entire foot, the impact on the feet, knees, and waist can be mitigated. Furthermore, by striking the heel, the body's center of gravity becomes easier to stabilize, making it easier to achieve balance while walking and reducing the risk of falling. Moreover, by striking the heel, the burden applied to the muscles and joints of the entire foot can be distributed, making it relatively less tiring even when walking for a long time. Furthermore, by striking the heel and then pressing the ground with the entire sole of the foot, energy loss can be suppressed and walking efficiency can be improved.

[0007] Here, people with bowlegs (genu valgum) tend to tilt their feet outwards when walking because their knees open outwards. Therefore, this puts excessive load on the outer side of the heel and the outer side of the foot. Landing on the heel becomes unstable, and the landing tends to be biased towards the toes or the inner side of the foot. Because this type of landing shifts the center of gravity forward and uses the muscles of the foreleg, it easily leads to thicker legs. Furthermore, it makes it difficult to maintain balance while walking, and walking becomes unstable.Furthermore, it puts a load on the foot joints, and if left untreated, it may lead to knee arthritis.

[0008] On the other hand, people with X-shaped legs (genu varum) have their knees turned inward, so when walking, their feet sometimes tilt inward, and the pressure easily concentrates on the inside of the foot and toes, causing excessive load on the inside of the heel and the inside of the foot. When landing on the heel, the body tends to tilt. In addition, the weight tends to be biased to one side, making it difficult to maintain balance, and walking becomes unstable, which may also increase the risk of falling.

[0009] The inventions disclosed in Patent Documents 1 and 2 have a simple structure and the function of correcting O-shaped legs by being designed as if the user is standing on tiptoe to walk. However, the disadvantage that O-shaped legs are unstable when landing on the heel is not sufficiently improved. Furthermore, Patent Documents 1 and 2 do not mention users with X-shaped legs.

[0010] The purpose of this invention is to provide a footwear with a simple structure that simultaneously possesses the following functions: Users with O-shaped or X-shaped legs naturally land on their heels while walking, allowing the body's center of gravity to smoothly shift outwards from the heel to the toes, thereby facilitating balance and adjusting posture. Furthermore, the invention aims to provide a footwear where, when standing or walking, the knees point forward, and the pelvis closes upon standing, providing support for correct posture simply by wearing the footwear. Additionally, the invention aims to provide a footwear where, through the unevenness of the insole, the point and sequence of foot contact during walking change, thereby enabling the use of the correct muscles and bones for walking, providing support to restore human muscles and bones to the correct position for health, allowing for correct standing and walking postures. Means for solving the problem

[0011] According to one aspect of the present invention, the footwear is characterized in that: the footwear has a footrest for placing a foot and an upper surface spanning the instep of the foot, the footrest taking the shape of the outer periphery of the foot and having a toe portion and a heel portion for placing the heel, the footrest being divided into an inner portion of the foot including the thumb and an outer portion including the little finger, further having a flat thick-soled area in the inner portion, the other portion of the footrest being a flat thin-soled area, the thick-soled area extending in the long side direction of the footrest from the toe portion through the portion corresponding to the thumb and its base to the portion corresponding to the inner longitudinal arch of the foot, the thin-soled area extending continuously in the long side direction of the footrest from the portions corresponding to the middle finger, ring finger, little finger and their bases through the portion corresponding to the outer longitudinal arch of the foot to the heel portion.

[0012] According to the present invention, the footwear is constructed such that when a user walks while wearing the footwear, the heel of the foot, in the thin-soled area, first touches the ground, and the user's weight is sequentially transferred from the heel through the lateral longitudinal arch of the corresponding foot, from the lateral part of the toes to the lateral part of the thick-soled area with the lugs. This allows the user's center of gravity to smoothly transfer outwards from the heel through the lateral aspect to the toes. Furthermore, the lateral longitudinal arch (foot arch) of the corresponding foot is a thick-soled area, preventing the user's center of gravity from shifting inwards. Therefore, regardless of whether the user has bowlegs or knock-knees, their weight is smoothly transferred from the heel to the toes in an outward-shifting manner. This allows the user to maintain a correct walking posture and adjust their body posture. This footwear provides support for the user when standing and walking, helping to restore the muscles and bones to the correct position for physical health, enabling proper walking. Users with O-shaped legs and X-shaped legs can adjust their posture by continuously using this footwear. Because they unintentionally become able to walk with one heel striking the ground, it also has the effect of exercising abdominal muscles, causing the knees to point outwards, and the hips and pelvis to close.

[0014] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.[First Embodiment] FIG1 is a perspective view showing the appearance of the footwear according to the first embodiment of the present invention, and FIG2A is a plan view of a pair of footwear. FIG2B is a diagram showing the relationship between the footwear and the user's foot. The footwear 1 is a so-called flip-flop, which has a footrest 10 for placing the user's foot and an eyelet 20 that functions as a shoe upper spanning the instep. FIG1 shows the footwear 1 that can be worn on the user's left foot. In the pair of footwear 1, the footwear 1R that can be worn on the right foot and the footwear 1L that can be worn on the left foot are symmetrical (see FIG2A).

[0015] The footrest 10 is made of rubber material or EVA carbamate material, etc., and is a flat plate component formed to take the outer periphery of the foot, which has a heel portion 10a for placing the heel 202 of the user's foot 200 and a toe portion 10b for placing the toes 201 of the user's foot 200. The foot pedal 10 has a flat, thick-soled area 120 on its inner side, and the other parts of the foot pedal have a flat, thin-soled area 100. The junction 130 between the thick-soled area 120 and the thin-soled area 100 is a chamfered inclined surface.

[0016] The shoe lugs 20 are made of cloth or synthetic resin and are composed of a front shoe lug 21 and a side shoe lug 22. The front shoe lug 21 extends upward from the plate surface of the foot pedal 10 and is the part that is held by the thumb 204 and index finger 205 of the user's foot 200, and is located at the toe tip 10b of the foot pedal 10. The side shoe lugs 22 are made of a rope-like or strip-like component made of cloth or synthetic resin, and are divided into an inner shoe lug 22a extending toward the side portion (hereinafter referred to as the inner side portion) on the thumb side of the foot pedal 10 and an outer shoe lug 22b extending toward the side portion (outer side portion) on the little finger side, with the front shoe lug 21 as the base. The inner shoe lug 22a and the outer shoe lug 22b of the instruction manual (page 3 / 6, CN 121908968 A 22b) are respectively fixed to the two sides of the arch area of ​​the footrest 10. The thick sole area 120 extends in a tongue shape from the toe tip 10b of the footrest 10 to the position 122 corresponding to the inner side of the end 22e of the side shoe lug 22 along the long side of the footrest 10.

[0017] Figure 2B is a diagram showing the relationship between the shoe 1 and the user's foot 200. If the line segment connecting the center of the forefoot lug 21 of the shoe 1 and the center of the heel portion 10a of the heel 202 where the user's foot 200 is placed is defined as the center line O-O, then the thick-soled area 120 of the footrest 10 extends in the horizontal direction from the inner part of the toe tip 10b, that is, the part corresponding to the big toe 204 and its base, to the junction portion 130 of the inner longitudinal arch (foot arch) 207 of the corresponding foot 200. That is, the thick-soled area 120 is slightly wider in the width direction of the footrest 10 near the position of the toe tip side, which is further forward of the forefoot lug 21, and the inner part of the end portion 22e of the side shoe lug 22, which corresponds to the forefoot lug 22, and slightly narrower in the middle position between them.On the other hand, the thin-sole region 100 extends continuously along the long side of the footrest 10 from the portion of the toe tip 10b, i.e., the portion corresponding to the middle, ring, and little fingers 206 and their bases, through the portion of the lateral longitudinal arch 208 of the corresponding foot, to the heel portion 10a. The heel portion 10a is a flat area without a thick-sole region and has a wide area sufficient to support the heel 202 of a user with poor balance, such as those with bowlegs or knock-knees.

[0018] FIG3 is a side view of the footwear 1, and FIG4 is a rear view of the footwear 1. In order to absorb the impact force on the foot when the heel strikes, the thin-sole region 100 of the footrest 10 has sufficient thickness. For example, depending on the size of the footwear 1, it has a thickness of about 25 mm to 35 mm. The thick-sole region 120 of the footrest 10 has a thickness H of, for example, 10 mm to 25 mm, depending on the size of the footwear 1. Therefore, the surface of the thick-sole region 120 has a height of, for example, about 50 mm from the bottom surface of the footwear 1.

[0019] The toe portion 10b of the footrest 10 is inclined in a manner that is higher than the other surfaces of the thicker sole area. That is, the toe portion has an inclined surface 10C that is higher than the thickness H of the thicker sole area 120 at the front end. Depending on the size of the shoe 1, the front end of the inclined surface 10C is higher than the plane that is the main part of the thicker sole area 120 at the thickness H, for example, by about 10 mm. This is because in the sandal 1 without an upper, the toes of the user's foot are prevented from sliding forward by the wedge effect caused by the inclined surface 10C of the footrest 10.

[0020] FIG5 is a schematic diagram showing the movement of the user's weight on the shoe when the user is walking in the shoe of the first embodiment. That is, FIG5 is a schematic diagram showing the movement of the user's foot on the main contact area (C) of the shoe 1 and the center of gravity (G) where the user's weight (center of gravity) is greatly affected, which is the situation when the user is walking in the shoe. When the user's foot is divided into two parts near the arch: the toe side and the heel side, and the toe side is further divided into the big toe side (inner side) and the middle, ring, and little toe sides (outer side), the portion of the transverse head of the adductor hallucis muscle (C3) in the "outer" part of the foot and the portion of the arch side in the flexor digitorum brevis muscle (C2) roughly correspond to the thin-soled area 100. When walking, the user of the footwear of the present invention first lands on the heel portion 10a (C1), which is the thin-soled area. At this time, the user's center of gravity also acts on the same heel position (G1) as (C1). When the user walks while wearing the footwear 1 of the present invention, the main contact area between the user's foot and the footwear 1 moves forward along the outer thin-soled areas (C2) and (C3) of the foot, and finally lands on the "outer" big toe portion (C4). Furthermore, the concentration of the user's weight also moves forward in the outer direction, just like the main contact area.That is, the user's center of gravity also shifts forward from the heel position (G1) of the foot in the manner of (G2), (G3), and (G4) around the outside of the foot. In this way, by shifting the user's center of gravity from the heel position (G1) to the thin-sole areas (G2) and (G3), the forward shift of the center of gravity can be avoided.

[0021] Furthermore, the thick-sole area 120 corresponds to the vicinity of the arch 207 of the foot. This thick-sole area 120 is connected to the arch of the user's foot and can prevent the user's foot from tilting excessively inward, thus preventing the center of gravity from shifting inward. As a result, the user's center of gravity can be guided from the heel (G1) to the big toe (G4) without shifting excessively inward. That is, even if the user has O-shaped or X-shaped legs, they can maintain a walking posture and the distance between their knees to be close to the standard shape. Instruction manual, pages 4 / 6, CN 121908968 A

[0022] Users with bowlegs and knock-knees, by wearing this shoe 1, shift their center of gravity to their heels when at rest, and their bones adjust to the correct posture. Simply by wearing this shoe 1, for example, standing in sandals, the user's pelvis will close. Simply by standing in sandals, support is provided to achieve the correct posture. Furthermore, the surface of the sandals has a height difference caused by the thin sole area 100 and the thick sole area 120. Through this height difference, the landing point and landing sequence of the foot will change when walking, thereby enabling the user to walk using the user's original correct muscles and bones. Therefore, by maintaining the correct posture while walking, the muscles used will change, resulting in the user closing their hips and pelvis. However, users with bowlegs and knock-knees cannot immediately obtain the desired effect by walking while wearing this shoe 1 without changing their consciousness. It is necessary to conduct walking training to properly wear this shoe 1. That is, it is necessary to conduct walking training with conscious heel strike (see Figures 6 and 7).

[0023] According to this embodiment configured as such, by wearing shoe 1, users with bowlegs can achieve a state where the center of gravity of the user's foot is properly lateral from the heel to the toes, and the knee spacing can be corrected to near standard. Furthermore, by wearing shoe 1, users with knock-knees can prevent excessive weight concentration on the inner side of the sole of the foot, and the knee spacing can be corrected to near standard. The sandals of the present invention provide support for the user to stand and walk while wearing shoe 1, so as to restore the human muscles and bones to the correct position for the body's health and enable proper walking.

[0024] Figures 6 and 7 are diagrams showing the desired walking condition of users with bowlegs or knock-knees when wearing sandals of the present invention for walking training. As shown in Figure 6, when the user of footwear 1 is walking, for example, it is necessary for the heel of the left foot 200 to land on the heel part 10a of the thin-soled area (point 1).Secondly, the outer half of the toe side of the left foot 200 contacts the thin-soled area 100 of the footrest 10, and the user's center of gravity is applied to the thin-soled area of ​​the shoe 1 (point 2). Then, the medial longitudinal arch (foot arch) 207 of the left foot 200 contacts the thick-soled area 120 of the footrest 10, and the user's center of gravity is applied to the thin-soled area 100 of the shoe 1, thereby allowing the center of gravity of the left foot to be transferred to the big toe. In the case of users with X-shaped legs, it is not easy to apply excessive center of gravity to the thin-soled area 100.

[0025] Furthermore, as shown in FIG7, with the left foot firmly held in the state of the thin-soled area and the thick-soled area of ​​the footrest 10 of the shoe 1 (point 3), the big toe of the right foot, whose center of gravity is located on the big toe, will finally leave the ground (point 4). This is because the toe tip of the footplate 10 becomes an inclined surface 10C, which is higher than the other surfaces of the thicker sole area, thereby preventing the toes of the left foot from sliding forward, and the big toe of the right foot will be the last to leave the ground. In this way, even users with O-shaped legs and X-shaped legs can correct the center of gravity of the user's foot to the proper position on the inside. Therefore, when walking, the weight is indeed smoothly transferred from the heel through the center of gravity of the outer longitudinal arch of the foot to the toes. In other words, even users with O-shaped legs and X-shaped legs can easily maintain balance while walking without leaning to one side.

[0026] Figure 8 is a diagram showing the state of the human skeleton 300 when a user with O-shaped legs walks from the front. When wearing ordinary shoes, users with O-shaped legs tend to concentrate pressure on the outer parts of the left and right feet 200R and 200L, resulting in a bad posture of bending the femur 302.

[0027] Figure 9 is a diagram showing the state of the skeleton of a user with bowlegs standing upright while wearing the shoes of the present invention, viewed from the front. When wearing the shoes 1 of the present invention, as previously explained, the user's weight moves from the heel through the inner part of the toes, i.e., the big toe, to the thick-soled area, which has the forefoot lugs. Therefore, the user's feet will not be in a bowleg state, but will maintain the correct posture shown in Figure 9. In the case of knock-knees, the user's feet can also be prevented from being in a knock-knee state, maintaining the correct posture.

[0028] Next, Figure 10 is a diagram showing the state of the skeleton 300 of a user with bowlegs standing upright while wearing the shoes of the present invention, viewed from the side, on pages 5 / 6 of the specification, 7 CN 121908968 A. A "good posture" of the human body refers to a state in which the "ear, shoulder, waist, knee, and ankle" are in a straight line. When wearing the shoes of this invention, users with bowlegs will have their posture corrected while standing upright, forming a straight line from the heel 202 of the foot 200 to the sternum 330.Furthermore, since walking is done with the heel 202 of the foot 200 in mind, it also has the effect of exercising the abdominal muscles 320 while the knees point outward and the hips 310 and pelvis close.

[0029] Next, FIG11 is a perspective view showing the appearance of the footwear according to the second embodiment of the present invention. FIG12 is a side view of the footwear according to the second embodiment. This footwear has a sole (footrest) 10 for placing the foot and an upper part 23 fixed to the outer periphery of the sole, the upper part 23 at least covering the instep for placing the foot on the sole. As in the first embodiment, the sole (footrest) 10 has a thin-sole region 100 and a thick-sole region 120. The shapes of the thin-sole region 100 and the thick-sole region 120 are almost the same as those of the footwear according to the first embodiment of the present invention. The upper part 23 replaces the lugs 20 of the first embodiment. Since the upper part 23 prevents the toes from sliding forward, the second embodiment of the footwear does not have a structure equivalent to the inclined surface 10C of the first embodiment. The shapes of the thin-sole region 100 and the thick-sole region 120 of the second embodiment of the footwear are the same as those of the first embodiment, except for the inclined surface, and their functions and effects are also the same.

[0030] As described above, the footwear related to the present invention has a simple structure and the following functions: users with O-shaped legs and X-shaped legs naturally land on their heels when walking, allowing the body's center of gravity to smoothly transfer from the heel to the toes in a lateral manner, thereby facilitating balance and adjusting body posture. Furthermore, when wearing the footwear, the knees point forward when standing and walking, and the pelvis closes simply by standing, providing support for correct posture. Furthermore, the shoe, through the unevenness of the insole, changes the point and sequence of foot contact during walking, thereby enabling the use of the correct muscles and bones for walking, providing support to restore human muscles and bones to the correct position for physical health, allowing for correct posture and walking. Furthermore, the unevenness of the insole creates a structure that facilitates kicking with the big toe during walking.

[0031] The embodiments of the present invention have been described above, but the embodiments of the present invention are not limited to the above embodiments.
