Description

  The present invention relates to a shoe insole.

  As an insole (insole pad) used for footwear, there has been proposed, for example, one in which various forms of irregularities are formed on an appropriate portion of the insole to correct a defect in a foot skeleton or a muscular action or to secure a good balance. (See Patent Document 1).

  For example, in the case of Patent Document 1, a raised portion provided in a spot shape outside the insole surface (the little finger side of the foot) and a concave portion provided in a spot shape inside the insole surface (the thumb side of the foot) are used for walking. It is arranged along the center of gravity shift line on the sole of the foot. In this way, there are many insoles that aim at various effects such as removing the distortion of the ankle joint, giving a massage effect, and improving the posture and motor function by appropriately arranging the ridges and recesses on the insole. Is coming out.

  On the other hand, as an element of human health, there is an effect of the distortion of the foot on the whole body. For example, in some cases, when the standing position of the foot collapses, the fibula is pulled downward as a result, and the balance is lost, causing distortion to spread throughout the body. The lowering of the fibula position affects the skeleton above the knee, exacerbating the problem as whole body distortion. That is causing various symptoms.

  Specifically, adverse effects on the fibula appear as follows. First, (1) due to the gravity load, the “talus” of the balancer slides forward and downward while twisting. (2) Next, the arch of the foot collapses, and the cubic and scaphoid bones are pulled down as a whole, and the arches of the five metatarsal bones also collapse. (3) Since the space below the calcaneus and the space below the cubic bone is lowered, the joint does not function as a spring and the joint between the fibula and the talus is lowered. Finally, (4) distortions such as knees and hip joints propagate and spread throughout the body. Therefore, it has been required to stabilize the fibula by supporting the positions of the calcaneus and talus through footwear worn on a daily basis, thereby preventing the propagation of distortion throughout the body.

  The shoe insole according to the present invention, a sole-shaped bottom provided on the sole of the shoe, and a front support projection formed to protrude from the bottom and support a plurality of metatarsal bones from the side of the shoe, Protruding from the bottom, comprising a calcaneal support protrusion formed to support the inside of the front of the calcaneus from the shoe sole side, the thickness of the calcaneus support protrusion in the front-rear direction is wide on the medial vertical arch side, It is formed narrow on the outer vertical arch side.

  According to the present invention, the foot is lifted from the metatarsal bone by the front support projection, and the front of the calcaneus of the lifted foot is supported by the calcaneus support projection formed wide and narrow on the inside to the outside of the calcaneus. The anterior can be lifted to return the talus to its ideal location and the fibula can be pushed up. As a result, the position of the fibula can be normalized, thereby improving health.

  FIG. 1 is a diagram showing a relationship between a raised portion of an insole according to the present embodiment and an arrangement of feet. FIG. 1 shows a case where the right foot is viewed from the sole. The feet shown in FIG. 1 include toes corresponding to the thumb, the index finger, the middle finger, the ring finger, and the little finger. Connected to the bone. The scaphoid and the talus are connected to the tip of the calcaneus, and the calcaneus is connected to the heel of the foot.

  A so-called outer vertical arch and an inner vertical arch are formed at the arch of the sole. The outer vertical arch is an arch shape formed in the direction from the heel to the little finger of the foot. The inside vertical arch is an arch shape formed from the heel to the thumb direction of the foot. Thus, the thumb direction of the left and right directions is defined as inside, and the little finger direction is defined as outside.

  The insole 10 shown in FIG. 1 is a sole-shaped bottom provided on a shoe sole, and has a size ranging from a part of a seed bone connected to a base phalanx to a part of a heel of a foot via a metatarsal bone. . FIG. 1 shows only the size necessary to explain the raised shape attached to the insole 10, but the insole 10 has a size extending to the further toe portion of the seed bone as in a normal size. It is good.

  The insole 10 is provided with a front support protrusion 11, a calcaneus support protrusion 12, and a heel support portion 13, each of which is formed as a raised portion to support and stimulate the sole of the foot, and It plays the role of lifting the place where it does.

  The front support protrusion 11 is formed so as to protrude from the insole 10 and support a plurality of metatarsals from the insole 10 side. The front support projection 11 has a configuration that protrudes from the insole 10 at a position corresponding to the first to fifth metatarsal bones. In particular, the anterior support projection 11 is a raised portion arising from the bottom between the second, third and fourth metatarsals and the insole 10.

  The calcaneus support projection 12 is configured to protrude from the insole 10 at a position corresponding to the front part of the calcaneus. The calcaneus support projection 12 is formed so as to protrude from the insole 10 and support the inside of the front of the calcaneus from the insole 10 side. The thickness of the calcaneus supporting projection 12 in the front-rear direction is wide on the inner vertical arch side and narrow on the outer vertical arch side. The calcaneus support projection 12 is formed so as to support the front of the calcaneus and the medial longitudinal arch as a top. The thickness of the calcaneus supporting projection 12 in the height direction is wide on the inner vertical arch side and narrow on the outer vertical arch side.

  The heel rear support portion 13 is configured to protrude from the insole 10 at a position corresponding to the heel bone rear portion. The heel rear support portion 13 is formed by projecting from the bottom rearward with respect to the calcaneus support projection 12.

  FIG. 2 is a diagram showing the height of the protrusion of the front support projection according to the present embodiment. As shown in FIG. 1, the front support projection 11 is formed in a horizontally long configuration that is short in the front-rear direction of the foot and long in the horizontal direction perpendicular to the front-rear direction of the foot. The height of the front support convex portion 11 is arranged right below the position corresponding to the second to fourth metatarsals, is lower at the lateral end, and is equal in height to the left and right so as to be higher at the center. It has become.

  FIG. 3 is a diagram showing the height of the ridge of the calcaneus support projection according to the present embodiment. As shown in FIG. 1, the calcaneus support projection 12 is formed in a horizontally long configuration that is short in the front-rear direction of the foot and long in the horizontal direction perpendicular to the front-rear direction of the foot. The height of the calcaneus supporting projection 12 is highest at the thumb side, that is, at the position of the second metatarsal, and gradually decreases as it proceeds toward the third and fourth metatarsals. .

  That is, the height of the calcaneus supporting projection 12 is high on the right and left sides of the thumb and low on the little finger side. Further, with regard to the width, the calcaneus supporting projection 12 is formed wide on the thumb side = inside and narrow on the little finger side = outside. In this way, the inside is high and wide, so that the calcaneus can be lifted forward and inside. As a result, the talus is returned to an ideal position, and the position of the fibula is pushed upward. In this way, the position of the fibula can be normalized, thereby improving health.

  FIG. 4 is a diagram comparing the height when the insole according to the present embodiment is mounted with the shape of the foot. 2 and 3 show the insole 10 and the foot to be worn from the back of the right foot, while FIG. 4 shows the insole 10 and the foot to be worn from the right side of the right foot, that is, from the outside. First, a front support projection 11 is provided on the side of the toe of the toe of the insole 10, and is configured to hit the metatarsal side of the seed bone. By supporting the second to fourth metatarsal seed bones, the arch behind the metatarsal bone is supported using the principle of leverage.

  The calcaneus is further advanced to the heel side, and a calcaneus supporting convex portion 12 is provided at a position in front of the heel to lift the calcaneus forward. By supporting the anterior calcaneus on the medial side, the arch of the foot is restored by returning the tarsal bone to a normal position, and the positional relationship between the tibia and fibula above the ankle is stabilized, and the whole body is balanced. be able to. Further, by providing the heel support portion 13, the lifted heel portion is held at the raised height.

  FIG. 5 is a diagram showing the action of the front support projection according to the present embodiment on the foot. First, the right foot (or left foot) is shown as a toe 21, a base phalanx 22, and another portion 20. For the sake of explanation, a human foot is divided and illustrated in the front-rear direction. Here, as described with reference to FIGS. 1 to 3, the front support protrusion 10 is provided in front of the insole 10.

  Due to the protrusion of the front support projection 11, a downward supporting force indicated by an arrow 24 is applied to the front of the other portion 20, and an upward supporting force indicated by an arrow 25 is applied to the rear of the other portion 20. In this way, the front support projection 11 indirectly pushes up the wedge-shaped bone by supporting the metatarsal bone. Further, as described later, the calcaneus supporting projection 12 indirectly pushes up the scaphoid and the cuboid. As a result, the arch structure can be indirectly supported by the front support projection 11 and the calcaneus support projection 12.

  FIG. 6 is a diagram showing the action of the calcaneus support projection according to the present embodiment on the foot. As described with reference to FIGS. 3 and 4, the front of the calcaneus is pushed up by the calcaneus supporting protrusion 12. The action of pushing the calcaneus forward is indicated by arrow 30. The talus then returns to its ideal location, as shown by arrow 31. In this manner, by supporting the calcaneus which has been inclined inwardly in front, the talus which has also been slid inwardly forward can be returned to the rear. The ability to return the talus to its ideal location allows for the distortion of the talar fibular joint to be corrected.

  Then, as shown by the arrow 32, the position of the fibula can be pushed upward. In this way, the fibula which has been pulled down in relation to the ligament can be returned upward. When the front of the calcaneus is pushed up by the calcaneus supporting protrusion 12, the positions of the cuboid and the scaphoid can also be positioned upward.

  Here, the insole 10 does not directly support the structural foot arch. This is to avoid losing the function of the spring of the arch structure. As a result, when the positional relationship between the tibia and the fibula returns to an ideal state, the tension of the muscles and fascia is eliminated, and the lower body is stabilized. As a result, tension in the pelvis and the whole body can be reduced.
