  According to the hallmark for correcting hallux valgus according to claim 4, at least a bottom member against which the back surface of the foot abuts is provided. Since there is an inclined surface inclined downward from the foot side toward the outer foot side and having an inclination angle of 45 to 50 degrees with respect to the horizontal plane, when walking with the hallux valgus footwear, the inclined surface of the bottom member Abutment can be made to follow the muscle abdominal muscles of the ankle muscles on the sole of the foot, and the muscles of the ankle muscles of the ankle are reliably and more effectively on the inclined surface by the pedestrian's own weight on the sole of the foot It is possible to press and pull the toe side toward the inner leg, and to correct the hallux valgus.

  An embodiment of the present invention will be described with reference to FIGS. A is a hallux valgus correction footwear, and the hallux valgus correction footwear A is generally composed of a bottom member 1, an outsole 2, and an upper member 3.

  The bottom member 1 is a member with which the foot sole of the footwear comes into contact, and the bottom member 1 has a thick abdominal abdomen 40a of the ankle abductor muscle 40 (see FIG. 4) (the origin of the spindle-like muscle, the middle part of the attachment) As shown in FIG. 3B, an inclined surface 11 that is inclined downward from the inner foot side f toward the outer foot side g is provided at a portion where the foot sole surface corresponding to the portion) abuts. The bottom member 1 is usually an insole of footwear, but the upper surface of the insole is covered with a sheet-like cosmetic material, or a ready-made footwear such as a cup insole separated from the insole. It may be a detachable attachment. The bottom member 1 is made of a high-strength material such as EVA (ethylene vinyl acetate copolymer) resin foam, foamed polyurethane resin, ABS resin, aluminum or the like so that the shape of the inclined surface 11 can be maintained. Used.

  As shown in FIG. 5 (for the sake of convenience, the foot 4 shows only the ankle abductor muscle 40, the scaphoid bone 41, and the cubic bone 44 for the sake of convenience), It is provided in the part which contact | abuts the foot sole surface 4a corresponding to 40a, and when the footwear A for hallux valgus correction | amendment is put on, the inclined surface 11 presses the muscle belly 40a with a pedestrian's own weight. The inclined surface 11 is provided so that the inclination angle θ with respect to the horizontal plane is 40 to 60 degrees.

  Here, the reason why the inclination angle θ of the inclined surface 11 is set to 40 to 60 degrees is to contact the foot bottom surface 4 a corresponding to the muscle abdomen 40 a of the ankle abductor muscle 40 along the inclined surface 11. . When the inclination angle θ is smaller than 40 degrees, as shown in FIG. 6A (for convenience, the foot 4 shows only the ankle abductor muscle 40, the scaphoid bone 41, and the cubic bone 44), as shown in FIG. When the surface 11 and the muscle abdomen 40a of the ankle abductor 40 are not in contact with each other and are separated to form a gap S, it becomes difficult to press the muscle abdomen 40a, and the inclination angle θ is larger than 60 degrees. As shown in FIG. 6B (for convenience, the foot 4 shows only the ankle abductor muscle 40, the scaphoid bone 41 and the cubic bone 44), the foot 4 is pushed in the direction of the arrow d, The force to press the muscle abdomen 40a of the ankle abductor muscle 40 decreases as the angle of inclination becomes steep and it becomes difficult to fix on the bottom member 1 due to the back surface of the foot being displaced, and the hallux valgus is corrected. This is because it is difficult to obtain the effect. In order to make the sole surface 4a corresponding to the muscle abdomen 40a of the ankle abductor 40 abut the inclined surface 11 more effectively, the inclination angle θ of the inclined surface 11 is provided in the range of 45 to 50 degrees. Is preferred.

  By the way, as shown to Fig.3 (a), you may form the toe part 1a with which the toe of the bottom member 1 contact | abuts in a substantially horizontal shape in the direction orthogonal to the longitudinal direction of the footwear A for hallux valgus correction. This is because the toe portion 1a has a substantially horizontal shape so that the toe portion (first toe) can be moved freely in the horizontal direction, and the toe portion can be easily corrected by rotating to the inner foot side. .

  The outsole 2 has a buffering action so that the foot is not directly subjected to an impact caused by unevenness of the ground contact surface when the hallux valgus correction footwear A touches the ground or the like, as shown in FIGS. As shown in (c), it is provided below the bottom member 1 and is fixed to the bottom member 1 by bonding or the like with an adhesive. The outsole 2 is made of a known material such as an EVA resin foam or a foamed polyurethane resin.

  The upper member 3 engages with the instep of the foot and fixes the foot to the bottom member 1. For example, as shown in FIG. 3B, both ends of the upper member 3 are connected to the bottom member 1. It is fixed between the outsole 2 with an adhesive or the like. The upper member 3 may cover substantially the entire upper surface like the sandal shown in FIG. 1, or may locally cover the toe portion like a pump. The upper member 3 is made of a known material such as polyester, polyurethane foam, genuine leather, or artificial leather.

  Next, the operation of the present invention will be described. When the pedestrian wears the hallux valgus correction footwear A, as shown in FIG. 5, the sole 4 a corresponding to the muscle abdomen 40 a of the ankle abductor 40 abuts against the inclined surface 11 of the bottom member 1 and walks. The slant surface 11 pushes back the back surface 4a in the direction of the arrow b by the reaction that the back surface 4a presses the slant surface 11 by the weight of the person. At this time, as shown in FIG. 4, the ankle abductor muscle 40 is attached to the inner leg side of the first proximal phalange 45 whose one end in the longitudinal direction is the heel and the other end is attached to the rib 43 of the heel. Since the muscle abdomen 40a is located in the middle of the ankle abductor muscle 40, when the muscle abdomen 40a is pressed, the muscle abdomen 40a is shaped like a boat as shown in FIG. Pressed against the bone of the foot such as the bone 41, the attachment portion 40b between the ankle abductor muscle 40 and the first proximal phalanx 45 is pulled in the direction of the arrow c. Then, the first proximal phalanx 45 located on the toe side rotates toward the inner foot side (the arrow e side in FIG. 7A) using the contact point h with the first metatarsal 46 as a support shaft. Then, as shown in FIG. 7 (b), the hallux that had been erected changed direction and returned to the normal position, and the hallux valgus was corrected.

  Therefore, in the present invention, it is a simple operation of walking while wearing the hallux valgus correction footwear A and forcibly pressing the muscle abdomen 40a of the ankle abductor muscle 40 on the inclined surface 11 by the weight of the pedestrian. It can be rotated by pulling the main hook toward the inner leg side, and the hallux valgus can be corrected.

  In addition, although the example which used the sandal was demonstrated in the Example mentioned above, this invention is not restricted to a sandal, It can use for various footwear, such as a sneaker and a boot.

It is the perspective view which cut | disconnected a part of footwear of the Example of this invention. It is a top view of the bottom member of FIG. FIG. 3A is a longitudinal sectional view of FIG. 2, FIG. 3A is a view cut along the line VV in FIG. 2, and FIG. 3B is a view cut along the line WW in FIG. FIG. 2C shows diagrams cut along the line XX in FIG. It is a figure for demonstrating the positional relationship of a bone of a foot | leg and a toe abductor. FIG. 4 is a schematic longitudinal sectional view when the footwear of FIG. FIG. 6A is a schematic longitudinal sectional view when the angle of the inclined surface in FIG. 5 is changed, FIG. 6A is a view when the inclination angle θ is less than 40 degrees, and FIG. The figure when it is larger than the degree is shown respectively. It is a figure for demonstrating the effect | action of the footwear of FIG. 1, and has shown the relationship between the bone | frame of the foot | leg and the toe abductor muscle seen from the foot back side.
