Description

  The present invention relates to footwear and an insole for footwear in which ideal walking and posture are formed by continuous use, and back pain and knee pain are gradually improved.

  Conventionally, various proposals have been made to prevent or ameliorate back pain of the user by devising the bottom structure of footwear. For example, as such, an auxiliary pad is affixed to the position of the reflection point of the sole such as back pain, and the back pain is improved by pressing stimulation when wearing shoes (Japanese Patent Laid-Open No. 11-146802), low elasticity This material reduces the direct strong impact and suppresses the generation of knee pain and back pain (Japanese Patent Application Laid-Open No. 2004-248942). By making the toe part higher than the heel part, the forward leaning posture is eliminated. There are those that improve the visceral function reduction, low back pain and the like (Japanese Patent Laid-Open No. 2005-160560).

  By the way, because modern people walk on asphalt and live on a flat floor, their toes are not used and the strength of their fingers is weak, and there is a tendency that vertical arches with raised arches are not formed. As a result, it is pointed out that walking with the crotch with the toe side opened and the center of gravity placed on the heel side and the toes opened outside without using fingers with flat feet, the back pain and knee pain are induced by the impact Yes. In addition, it has been pointed out that the posture becomes unbalanced and the back pain and knee pain worsen further because the center of gravity is biased toward the dominant foot side, and the shoulder height is different on the left and right.

The ideal walking is to move lightly on the heel side and then move forward by kicking the ground with your toes (especially the thumb). Keeping the heels forward and lowering the position of the buttocks in the footwear, making it possible to bend the toes downward even when wearing the footwear, and the toe side does not open outward Is required.

  The footwear 1 of this embodiment has a toe placement recess 4 formed at a depth 3 in which a toe can be bent downward in a vicinity 3 where a toe is located in a bottom 2 on which the foot is placed. In the bottom portion 2, the vicinity 5 of the portion where the heel is placed is provided with a heel placement recess 6 that is formed higher than the toe placement recess 4 and in which the heel is placed. Is characterized in that the outer side 7 is formed higher than the inner side 8. Hereinafter, each configuration will be described in detail.

  The footwear 1 in this embodiment is a slipper, but is not limited to this, and any footwear may be used. For example, athletic shoes, leather shoes, nurse shoes, shoes in general, sandals, sandals, etc. But you can.

  Since the footwear 1 is a slipper, it is composed of a bottom 2 and an upper 9 attached to the bottom 2 as shown in FIG. Further, a toe placement recess 4 is provided in the vicinity 3 of the bottom 2 where the toes are located. The toe placement recess 4 is formed to a depth that allows the toe to be bent downward. When the slipper 1 is put on and then the toe is bent downward, the finger is bent at a substantially right angle. Even if it is made to do, it has a depth to the extent that the toe slightly abuts against the bottom surface 4a of the recess 4 or just does not abut. More specifically, the depth of the recess is preferably 10 mm or more although it depends on the size of the user's foot.

  As a material for forming the bottom portion 2, known materials can be used. For example, rubber materials, synthetic resins, wood, paper materials, foams, and the like can be preferably used. Further, the bottom portion 2 of this embodiment is composed of an integrally molded product in which the bottom portion is formed by a single plate-like body and the concave portion 4 is formed at the tip end portion, but is not limited thereto, A plate-like laminate of which the bottom part is formed and the number of tip parts is reduced to form a recess is also included in the scope of the present invention. Moreover, the lower surface of the bottom part 2 is formed in a plane as shown in FIG.

  As described above, the footwear 1 of the present invention has a toe formed in the vicinity of a portion 3 where the toe is located in the bottom 2 on which the foot is placed so that the toe can be bent downward. Since it has the arrangement | positioning recessed part 4, even if it wears the footwear 1, operation | movement, such as bending a toe down, can be performed freely and the force of a toe will also be strengthened gradually. As a result, a vertical arch with the arch warped is formed, and ideal walking is possible. Further, by bending the toes downward, the muscles on the back side of the legs are stretched and the waist enters, and the back muscles are stretched to form an ideal posture. These combined actions gradually improve back pain.

  Further, as shown in FIG. 4, the vicinity 5 of the bottom portion 2 where the heel is placed is formed higher than the inner bottom surface of the toe placement recess 4 and the heel placement recess 6 in which the heel is disposed. I have. In this embodiment, the vicinity 5 of the bottom 2 where the heel is placed rises one step higher than the portion between the vicinity 5 where the heel is placed and the inner bottom surface of the toe placement recess 4. It is comprised so that it may rise two steps from the inner bottom face of the recessed part 4 for arrangement | positioning. Thus, by forming the vicinity 5 of the part on which the heel is placed higher than the inner bottom surface of the toe placement recess 4, the toe side can be lowered to maintain a forward leaning posture, and the waist and knees can be maintained. It is possible to avoid applying a load. In particular, as in this embodiment, it is more preferable that the bottom portion 2 is configured in a three-stage structure from the front end side toward the rear end side, so that the entire foot can be prevented from lowering toward the front end side. Furthermore, it is prevented that a wrinkle slips down by providing the wrinkle arrangement recess 6 in which the wrinkle is arranged.

  Furthermore, as shown in FIG. 2 or 3, the bottom 2 is formed such that the outer side 7 is higher than the inner side 8. As a result, the toe side is prevented from opening outward, and the crotch becomes a crotch and the center of gravity moves to the rear side, thereby restraining the waist from being burdened.

  As shown in FIG. 1 or FIG. 2, a mother-child sphere arrangement recess 10 is formed in the vicinity of the portion where the vicinity of the mother-child sphere (reference numeral 20 in FIG. 5) is placed. As described above, the mother-child sphere 20 is arranged in the mother-child sphere arrangement recess 10 to enable ideal walking using the mother-child sphere. Is disposed in the mother-child ball placement recess 10 so that the left and right distortions of the body are gradually eliminated and the height of the shoulders becomes the same on the left and right. In addition, since the convex portion is formed between the mother-child ball arranging concave portion 10 and the heel arranging concave portion 4, the inner arch 21 shown in FIG. 5 is also easily formed. The mother-child sphere 20 (see FIG. 5) refers to a substantially spherical body portion that is near the base of the thumb and serves as a movement fulcrum of the thumb.

  As shown in FIG. 1 or FIG. 2, a ridge 11 is formed near the center of the bottom 2 along the longitudinal direction. As a result, the front arch 22 shown in FIG. 5 is easily formed.

  As shown in FIG. 1 or FIG. 4, a mountain-shaped convex portion 12 is formed outside the bottom portion 2. Thereby, the outer arch shown in FIG. 5 is easily formed.

  As described above, in the footwear of the present invention, the toe placement concave portion formed to a depth where the toe can be bent downward is provided in the vicinity of the portion where the toe is located in the bottom portion on which the foot is placed. Since it is provided, it is possible to freely perform operations such as bending the toes downward even when wearing footwear. Further, the vicinity of the portion where the heel is placed in the bottom portion is formed higher than the toe placement concave portion and the heel placement concave portion in which the heel is arranged is provided, so that the toe side is lowered and the forward tilting posture is maintained. The buttocks do not slide down in the footwear. Furthermore, since the bottom part is formed higher on the outer side than on the inner side, the toe side does not open outward. By adopting these three basic structures, ideal walking and posture are formed, and back pain and knee pain are gradually improved. Furthermore, the footwear of the present invention is formed so that the bottom of the bottom of the footwear is flat, the vicinity of the part on which the heel is placed among the bottom is the highest, the second is formed with a high outside, Thirdly, the inner side is formed lower than the outer side, and it is configured so that the vicinity of the part where the toes are placed is the lowest so that the fingertip can kick the ground as the last movement during walking. This makes it possible to incline the entire foot inward, walk in a forward leaning posture, and use the toes and muscles of the foot correctly. Even when sitting down, the toes can be bent downward, so that the user can sit with the back muscles extended and the posture is corrected. Unlike the conventional case where the convex part is simply formed near the part where the arch is placed and apparently the vertical arch is formed, each part of the foot has been devised so that its function can be fully demonstrated. If you continue to use it, you will naturally get an ideal walk without resistance, and as a result, back pain, knee pain, and left / right distortion of the body will be resolved.

  In addition, a concave portion for mother-and-ball sphere placement is formed in a portion of the bottom where the vicinity of the mother-child sphere is placed, a convex ridge is formed in the vicinity of the center in the longitudinal direction of the bottom, and a convex portion having a mountain shape is formed outside the bottom. Has been. When these three structures are added to the above basic structure, three arches are not easily formed, and the effect of gradually improving back pain and knee pain when ideal walking and posture are formed becomes more prominent. .

  Further, as shown in FIG. 1, the upper cover 9 has an inner belt-like body 9b having a base end side portion fixed to the inner edge portion of the bottom portion 2 and a connecting metal fitting 9a at the front end side portion, and a base end side portion having a base end side portion. It has the outer side strip | belt body 9c connected with the inner side strip | belt-shaped body 9b by being fixed to the outer edge part of the bottom part 2, and having the front end side part inserted in the metal fitting 9a for connection. The outer side belt-like body 9c is configured so that the length of the outer side band-like body 9c can be adjusted by an adhesive member (not shown) such as a magic tape (registered trademark) after the front end side portion is inserted into the connection fitting 9a. By constructing the upper in such a length-adjustable structure, the user can hold the upper according to the size of the foot, and the foot can be arranged and fixed at a more appropriate position with respect to the footwear. .

Next, the insole for footwear of the present invention will be described.
The insole for footwear according to the present invention is a plate-like body arranged on the upper surface of the bottom of the footwear, and when the plate-like body is arranged in the footwear, the toe is lowered in the vicinity of a portion where the toe is located. A toe-arrangement recess having a depth that can be bent toward the upper side is configured, and a portion where the heel is placed is higher than the toe-arrangement recess and a heel-arrangement recess in which the heel is disposed Further, the insole for footwear is characterized in that the outside of the bottom portion is configured to be higher than the inside.

  As a specific example, for example, in the structure of the bottom portion 2 of the footwear 1 described above, the vicinity 3 (the tip portion having a substantially crescent shape in plan view) where the toe is located including the toe placement recess 4 is deleted. In addition, the thickness required for the bottom of the footwear (for example, the thickness between the inner bottom surface of the toe-positioning concave portion 4 and the back surface of the bottom portion is removed to the rear end in FIG. 4). Since the structure of each part and the function and effect of the structure in this embodiment are the same as those of the footwear 1, the description thereof is omitted.

  As another example of an insole for footwear, an uppermost plate-like body, an adhesive layer constituting an intermediate layer provided in the lower layer of the plate-like body, and a lowermost layer provided in the lower layer of the adhesive layer Those composed of a release layer are also included in the category of the insole for footwear of the present invention. In this embodiment, the plate-like body is a portion disposed on the upper surface of the bottom of the footwear, the adhesive layer is a portion for bonding the plate-like body to the upper surface of the bottom of the footwear, and the release layer is an adhesive layer.
