Description

  The present invention relates to a shoe, and in particular, to a shoe in which the remaining four fingers can sufficiently perform their functions by pushing and opening a mother toe outward in the shoe.

  Usually, a shoe has a hollow toe portion so that each of five fingers can move as well.

  However, in footwear that prioritizes aesthetics, such as high heels, or footwear that fits closely to the foot, such as athletic shoes, the foot is pushed to the second finger by the footwear during walking or running. At the same time, the fifth finger is pushed to the fourth finger side, and the action of tightening the toes in the left-right direction is likely to occur, and the hallux valgus is easy to bother.

  Therefore, in order to prevent and correct hallux valgus, there has been proposed a sandal provided with a cylindrical insertion portion into which each of the five fingers of the foot is inserted separately (see, for example, Patent Document 1).

JP 2002-345501 A

  In high heels, aesthetics are given top priority, so it is impossible to provide a cylindrical insertion part that inserts each finger separately, but in sports shoes it is not impossible to provide an insertion part to prevent hallux valgus .

  However, the thickness and length of the toes vary greatly from person to person, and there is no problem when making them as custom-made items. There was a risk that it would not work properly.

  The present inventor has been researching in view of such a current situation, and in the athletic shoes, the right and left direction acting on the four fingers other than the mother toe is eliminated only by eliminating the pressure on the second finger by the mother toe. It was found that stress can be greatly relieved.

  While developing athletic shoes based on this knowledge, the present invention has been achieved.

  In the shoe of the present invention, in a shoe provided with a shoelace on the upper part, a pressing body that pushes and opens the heel to the outside by pressing the heel abductor from the side, and the outside is pushed and opened. And a belt for holding the mother torso in a state where the body is held.

Furthermore, the shoe of the present invention is also characterized by the following points.
(1) The pressing body is provided along the first metatarsal in the inner part between the upper part and the shoe sole.
(2) The belt body has one end attached to the sole of the shoe under the toe, and the other end is pulled out from the slit provided in the instep on the toe to the upper surface of the instep, It is fixedly attached to the upper surface of the door via a hook-and-loop fastener.
(3) A covering material for covering the slit is provided on the upper part.

  In the shoe of the present invention, a pressing body that pushes and opens the main heel outward by pressing the heel abductor from the side, and a belt body that holds the main heel in a state of being pushed open outward. By providing, it can be held in a state where it is pushed outward in the outward direction, so that the pressure on the second finger side by the mother's heel can be eliminated, and further, the mother's heel may crawl into the lower side of the second finger. Can be prevented.

  In particular, the mother's heel is not only held in place but also pushed outward, so that the remaining four fingers are not subjected to extra stress and each finger Since it is in an independent state, that is, a finger is in an open state, each finger can fully exert its function and an improvement in athletic ability can be expected.

  The shoes of the present invention may be not only athletic shoes worn at the time of athletic competitions, but also casual shoes used in daily life and business shoes. As a result, it becomes a bare foot sensation and the stability during walking can be improved.

  The shoe of the present invention is a shoe provided with a shoelace on the upper part, and a pressing body that pushes and opens the heel to the outside by pressing the heel abductor from the side, and is pushed to the outside. And a belt for holding the mother's toe in the state of being. Here, to push and open the mother toe outward means that the mother toe is displaced from the normal state where nothing is done to the side opposite to the second finger side.

  As shown in FIG. 1, the shoe includes a foot-shaped shoe sole portion 11, an instep portion 12 provided along the instep portion of the foot, an inner portion 13 provided along the inside portion of the foot, There are an outer part 14 provided along the outer part of the foot and a rear side part 15 provided along the rear part of the foot, while the upper part 12 is folded back into the inner part 13 and the outer part 14 A crossed shoelace 20 is provided, and the shoelace 20 adjusts the wearing state of the shoe so that a sense of unity between the shoe and the foot can be obtained.

  The shoelace 20 is an adjusting means for adjusting the wearing state, and is not a shoelace 20 itself, for example, a belt-like adjustment piece (not shown) provided with a surface fastener on the back surface on the front end side. What is adjustable by attaching to the upper part 12 or the outer part 14 or the inner part 13 is the same adjustment means as the shoelace 20 in function, and such an adjustment means is used in the present invention. For convenience of explanation, it will be referred to as a shoelace 20.

  As shown in FIGS. 2 to 5, the pressing body 30 that presses the heel abductor from the side is bulged inwardly on the inner side 13 between the upper 12 and the shoe sole 11. Provided. In FIG. 2, 31 indicates the ankle abductor muscle.

  In particular, in the pressing body 30, in order to press the ankle abductor muscle 31 from the side, a groove that is provided at a predetermined distance from the shoe sole 11 and that extends in the front-rear direction at a substantially central portion in the vertical direction. A concave U portion is provided.

  When the pressing body 30 is not provided separately from the shoe sole portion 11 but, for example, a bulging body (not shown) bulged upward is provided on the shoe sole portion 11, the bulging body is a main body. Not only the abductor 31 but also the arch ligament (not shown) will be pressed, and the arch ligament will be strongly pressed. Will be bent. Further, in this case, even if the heel abductor 31 can be pressed by the bulging body, the bulging body presses the heel abduction muscle 31 diagonally from the lower side toward the upper side. Thus, in many cases, the mother bend is bent downward or obliquely downward, and the mother can hardly be pushed open outward.

  That is, in order to push the toe outward, the pressing body 30 needs to press only the toe abductor muscle 31 instead of the arch ligament, and the inside is separated from the shoe sole 11 by a predetermined distance. Must be provided in part 13.

  Note that the entire pressing body 30 does not need to be separated from the shoe sole 11, and it is sufficient that the pressing body 30 can press the ankle abductor 31 in a substantially horizontal direction.

  Furthermore, in the present embodiment, a depression U is provided at a substantially central portion in the vertical direction of the pressing body 30, and the depression U has a curved shape along the foot shape of the first metatarsal 32 portion. The first metatarsal 32 part is in surface contact with the foot. Therefore, the pressing body 30 can be in a state in which the ankle abductor muscle 31 is securely sandwiched together with the first metatarsal bone 32, and the ankle abductor muscle 31 can be reliably pressed substantially in the horizontal direction. Furthermore, while the pressing body 30 is in surface contact with the foot of the first metatarsal 32 portion, it is possible to prevent excessive compression of the ankle abductor muscle 31 while improving the fit. A feeling of comfort can be improved.

  In this embodiment, the depression body U is provided with the depression U. However, the depression body U is not necessarily provided with the depression U, and the depression body 30 that is simply projected in a bulging shape is pushed by the foot. The required pressing surface may be formed while being recessed by elastically deforming.

  It is sufficient that the length of the pressing body 30 in the front-rear direction is about the length of the first metatarsal 32. By providing the pressing body 30 along the first metatarsal 32, the outside of the mother It is possible to effectively press the rotator 31 and push the thorns outward. The pressing body 30 may be longer than the first metatarsal 32 as necessary.

  The pressing body 30 is preferably formed of an elastic material such as urethane foam, and the pressing body 30 having a predetermined shape is attached to a predetermined position of the inner side portion 13 of the shoe with an adhesive or the like, or is sewn to a predetermined position. Can be easily provided.

  As shown in FIGS. 6 and 7, the belt body 40 has one end attached to the shoe sole 11 under the heel and the other end side from the slit 41 provided in the upper portion 12 on the heel. It can be pulled out to the upper surface of the covered portion 12 and can be fixedly attached to the upper surface of the instep covered portion 12 via a surface fastener 42. In particular, the band body 40 can hold the main body with the main body pulled in the outward direction and can be held open.

  As shown in FIG. 1, a pile fabric 43 is attached to the upper surface on the toe side of the upper portion 12 so that the hook and loop fastener 42 attached to the belt body 40 can be engaged. By adjusting the engagement position of the hook-and-loop fastener 42 to the pile fabric 43, the pulling direction of the main hook by the band 40 can be adjusted as appropriate, and the outer side of the main hook is surely adjusted to the size and length of the main hook. It can be held in a state of being pushed open in the direction.

  It should be noted that a relatively large force is easily applied to the toe portion of the upper portion 12 to which the pile fabric 43 is attached because the end portion of the band body 40 is engaged, and when wrinkles are generated by the action of the band, Since there is a risk that the pulling of the mother's body by the body 40 may be eased, it is desirable to make it as hard as possible.

  The belt 40 is made of a fabric having low stretchability, and an end portion is attached to the shoe sole 11 using an adhesive or the like. In particular, by providing the end of the belt body 40 at a position where it can be stepped on by the toe, it is also fixed by being stepped on by the toe, so that it is difficult to come off the shoe sole 11. Furthermore, by setting the end portion of the belt body 40 to a position below the main body, the belt body 40 can be reliably held while being pulled in the direction of pushing the main body outward.

  The slit 41 is provided as a gap that allows the band body 40 to pass along the main body on the main body. If the gap dimension of the slit 41 is too large, fine powders such as sand and pebbles are likely to enter. Therefore, it is desirable that the gap is as small as possible. As will be described later, when the slit 41 is covered with the covering material 44, the gap dimension of the slit 41 may be increased to be used as a vent hole, or by increasing the gap dimension of the slit 41. Thus, even a user with a relatively small mother fold can reliably hold the mother fold in the outward direction.

  In this embodiment, the upper part 12 is provided with a covering material 44 for covering the slit 41. By covering the slit 41 with this covering material 44, fine particles such as sand from the slit 41 during running. The powder is prevented from entering the shoe.

  That is, as shown in FIG. 8, the covering material 44 is mounted on the upper surface of the upper portion 12 as a substantially semicircular sheet piece that matches the shape of the toe portion of the shoe. In particular, the covering material 44 is fixedly and appropriately attached to the upper part 12 by an adhesive or stitching at an appropriate position on the upper side of the four fingers excluding the mother toe, and is closer to the toe than the slit 41. A hook-and-loop fastener 45 is provided on the back surface of the belt, and is engaged with a pile fabric 43 provided on the upper portion 12 so that the slit 41 can be covered.

  Further, the covering material 44 covers the slit 41 and prevents not only fine powder such as sand from entering from the slit 41, but also overlaps the belt 40 attached to the pile fabric 43, so that the belt body It can prevent 40 locks from coming off. Moreover, since the band 40 can be prevented from being noticeable, the appearance can be improved.

  The band body 40 is attached to one end of the shoe sole 11 under the heel, and the other end is pulled out from the slit 41 provided on the upper hood 12 above the heel to the upper surface of the upper hood 12. The band 40 inserted between the mother toe and the second finger can be pulled and held in a position where the mother toe is pushed outward. In particular, since the band 40 is attached to the shoe sole 11 under one end of the band 40, the band 40 can be reliably held by the band 40 regardless of the shape or size of the different hail for each person.

  In the shoe configured as described above, when the shoelace 20 is loosened and the shoe is inserted into the shoe from the tip of the foot when the shoe is put on, the toe abductor 31 is pressed by the pressing body 30 so that the toe is outward. Is pushed and opened, and the space between the mother toe and the second finger is sufficiently opened, so that the shoe can be put on while the belt 40 is smoothly inserted between the mother toe and the second finger.

  After putting on the shoe, the shoelace 20 is tied, and the presser 30 sufficiently presses the toe abductor 31 as shown in FIG. 6 to push the toe outward, and then in FIG. As shown, pull the end of the band 40 pulled out to the upper surface of the upper part 12 to fix the band 40 and fix it on the upper surface of the upper part 12, so that Holding while pulling in a state of being pushed open in the direction.

  At this time, the remaining four fingers are not pressed by the mother toe and are opened to each other as shown in FIG. 7 because the mother toe is pushed outward.

  Therefore, the four fingers excluding the mother's mother can fully perform their respective functions, and can improve athletic ability. That is, in athletics, for example, since the ground can be reliably bitten and kicked through each finger, the loss of leg strength is reduced, and an improvement in running ability can be expected.

  The end of the band 40 is fixedly mounted while pulling the main body with the band 40, and then the covering material 44 is mounted on the upper surface of the upper part 12.

  As another embodiment, when used in an environment where it is difficult for fine powder to enter from the slit 41, such as in a track competition, as shown in FIG. 9, a covering material that covers the slit 41 is not provided. May be. In FIG. 9, the same code | symbol is used with respect to the same structure as embodiment mentioned above, and the overlapping description is abbreviate | omitted.

  In the shoe of the present embodiment, the belt body 40 to which the pile fabric 43 ′ to which the hook-and-loop fastener 42 attached to the end portion of the belt body 40 is fastened is attached at a predetermined position of the upper part 12 and the main body is pulled. The end of the hook is engaged with the pile fabric 43 ′ so that the main hook can be pushed open and held in an open state.
