Description

  The present invention relates to an insole attached to the bottom of a shoe and a shoe having a special bottom.

  Originally, when people walk, they use their toes and heels to walk, but in modern people who wear shoes, there are many people who walk using only their heels and tactile balls. . That is, there is almost no mobility of the toes inside the shoe, and the toes cannot be used accurately, and walking is performed. For this reason, when walking, there was a problem that an excessive load was applied to the ligament that stabilizes the shape of the foot.

Various shapes of conventional insoles and shoe bottoms have been devised, mainly for cushioning (for example, Patent Document 1).
JP 2004-313774 A

  Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide an insole and shoes that can be used accurately by a toe during walking and the like.

  The present invention has been made to solve the above-described problems, and the feature of the insole according to the present invention is an insole that is attached to the bottom of a shoe, and the wearer is in a state of being attached to the bottom of the shoe. A toe abutting portion that abuts on the toes of the toe is made of an elastically deformable member, and the toe abutting portion is more than the bottom of the shoe on which the wearer's foot touch ball abuts. The surface is provided so as to be high.

  Further, in the shoe according to the present invention, the bottom portion is formed by an elastically deformable member having a toe contact portion that contacts the toe of the wearer's foot, and the toe contact portion is The surface of the wearer's foot is provided to be higher than the portion where the ball touches.

  In the present invention having the above-described configuration, the toes of the wearer's foot come into contact with the toe contact portion made of a member that can be elastically changed, and thus the toes can be used accurately. It becomes like this. That is, the wearer's toes abut against the toe abutment portion, and the toe abutment portion is deformed by the pressure of the toe, and therefore the toes are bent and grasped / gripped by the toes. Thus, even those who have not been able to use their toes accurately until now can move their toes. In addition, since the timing of ground contact of the toes is advanced, the ground contact surface can be stably stabilized by performing a gripping / gripping movement with the toes. Moreover, since such an exercise | movement is made, a plantar muscle can be trained similarly to towel gather training, for example. As a result, the stable contact area of the soles when walking and standing is maintained, and the center of gravity of the body with the knee bent is not lowered, the knee is stretched, and the weight is increased at the hip joint. Therefore, it is expected that the center of gravity moves upward, the psoas major muscle of the connecting muscles of the upper and lower limbs functions more, and the trunk is stabilized. For this reason, the operation | work which goes down stairs can be performed in the state which extended the knee, and does not put a burden on a knee. That is, for example, even if the psoas muscle does not function very well, the ground contact area can be stably stabilized especially by descending the stairs by advancing the ground contact timing. Furthermore, even for Japanese people with smaller foot sizes and wider foot widths than Westerners, weight transfer from the little finger to the thumb can be optimized, and at the same time, the axial pressure of the knee joint increases and the hip joint increases. The burden on the knee can be reduced by moving the weight. As a result, the balance of pelvic rotation can be maintained and the transition of symptoms (disorders) to the foot, knee joint, hip joint, waist, and neck can be prevented. Therefore, in the future aging society, it is possible to prevent falls and injuries, and there is an advantage that the burden is reduced even in the position of caring for the elderly.

  In the present invention, the height of the top part of the toe contact part is preferably 4 mm or more, more preferably 5 mm, more than the bottom part of the shoe with which the wearer's foot touch ball comes into contact. That's it. Further, the height of the top of the toe contact portion is preferably 25 mm or less, more preferably 20 mm or less than the bottom of the shoe with which the wearer's foot touch ball comes into contact. Here, “the top of the toe contact part” means the highest part of the toe contact part when the toe contact part is not a flat surface.

  Moreover, in this invention, it is preferable that the said toe contact part employ | adopts the structure by which the site | part corresponded to a thumb among the said wearer's toes is provided so that separation | detachment is possible.

  Accordingly, even a person having symptoms such as hallux valgus can be easily worn by removing the portion corresponding to the thumb of the toe contact portion. Furthermore, by using the height of the toe abutment during walking and changing the force to hold the thumb adductor muscles, the weight can be easily moved (tilted) to the thumb. -External rotation can be promoted, the burden on the knee can be reduced, and the effects of strengthening the psoas muscles can be expected by training the plantar muscles.

  In the invention of the present application, the insole body formed in a shape substantially the same as the bottom of the shoe to be laid on the bottom of the shoe, and the toe contact part attached to the toe portion of the insole body It is preferable that the insole is comprised from these.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.
FIG. 1 is a schematic plan view of an insole according to an embodiment of the present invention. FIG. 2 is a schematic side view of the insole of the same embodiment. FIG. 3 is a schematic plan view for explaining a state where the thumb contact portion of the insole according to the embodiment is removed.

  As shown in FIG. 1, the insole 100 of the present embodiment is laid on the bottom of a shoe, and has an insole body 110 formed in a shape substantially the same as the bottom of the shoe, and one of the insole body 110. And a toe contact member 120 attached to the front portion. The toe contact member 120 has a height of 5 to 20 mm (L in FIG. 2). Therefore, the surface of the toe contact member 120 is more than the surface of the insole body 110. 5-20 mm higher.

  Here, as the insole body 110, for example, natural rubber, synthetic rubber or the like that is surface-coated can be adopted.

  In addition, the toe contact member 120 is constituted by a member that can elastically deform the toe contact member 120 that contacts the toes of the wearer's foot. Specifically, the toe contact member 120 can be made of, for example, a silicon-based material, a gel-based material, a urethane-based material, a polyolefin-based material, a polyethylene-based material, or the like. Note that the toe contact member 120 may be configured as appropriate from a single sheet material or a multi-layer sheet material.

  The toe contact member 120 includes a toe contact part 123 corresponding to the thumb of the wearer's toes and a toe contact member main body part 121 to which another toe (small finger or the like) contacts. The thumb contact portion 123 is provided so as to be detachable from the toe contact member main body portion 121 and the insole main body 110.

  In addition, although the said embodiment demonstrated what consists of the said structure, this invention is not limited to this, A design change is suitably possible within the range which this invention intends.

  That is, in the above-described embodiment, only the insole 100 laid on the bottom of the shoe has been described. However, for example, the shoe bottom itself having the structure as in the above-described embodiment also falls within the intended scope of the present invention. Is within. Moreover, although the insole 100 of the said embodiment demonstrated what the toe contact member 120 was attached to the insole main body 110, for example, it consists only of the toe contact member 120 and can be attached to the bottom part of shoes. Even if it exists, it is in the range which this invention intends. Further, even in the insole attached to the bottom of the shoe, it can be applied not only to athletic shoes but also to various shoes such as women's shoes such as high heels.

  Moreover, in the said embodiment, although the surface of the toe contact member 120 was the same surface, this invention was not limited to this. In other words, for example, there is a shape in which only the portion that contacts the thumb is slightly lower, or an arch shape in which the central portion (middle finger) is higher than the outside (thumb or little finger). It is within the range intended by the present invention. Furthermore, a toe contact portion having a shape that is lower in the side view than in the rear (heel side) and in front (toe side) is also within the range intended by the present invention.

  Moreover, in the said embodiment, although what comprised a toe contact part by the toe contact member 120 which consists of a single member was demonstrated, this invention is not limited to this, For example, consists of multiple layers It is also possible to form a toe contact part, to dispose another member in a plane, or to configure the toe contact part from a plurality of members. Furthermore, the toe contact portion having elasticity is higher in the central part than the outside, and the toe is provided in an arch shape as described above when worn, and is also within the intended scope of the present invention. It is.

It is a schematic plan view of the insole of one Embodiment of this invention. It is a schematic side view of the insole of the embodiment. It is a schematic plan view for demonstrating the state which removed the thumb contact part of the insole of the embodiment.
