Description

Insoles for shoes

The invention relates to an insole for shoes.

Conventionally, there has been known a structure in which an insole for shoes includes a structure that supports the convex portion of the front of the calcaneus from the sole of the foot (see, for example, Patent Document 1).

In Patent Document 1, the front convex support of the calcaneus is used to stabilize the calcaneus, and the arch of the sole of the foot is maintained in a natural shape to support the foot in a balanced manner. The conventional shoe insole system can easily achieve balance of the foot, and can easily generate propulsive force during walking and traveling, so as to seek stability and sportiness at the same time.

[Prior Technical Literature] [Patent Literature]

[Patent Literature 1] International Publication No. 2014/203399

However, although the above-mentioned conventional shoe insole can achieve both stability and sportiness at the same time, there is a problem in that it is not easy to obtain the exercise effect when walking.

Therefore, an object of the present invention is to provide an insole for shoes that can ensure stability and sportiness and can easily obtain a sport effect.

The insole for shoes of the present invention includes: a calcaneal anterior support convex portion that abuts against the anterior portion of the calcaneus of the foot in order to maintain the medial longitudinal arch of the foot, the lateral longitudinal arch of the foot, and the lateral arch of the foot; and the calcaneus The front supporting convex portion maintains the medial longitudinal arch, lateral longitudinal arch, and lateral arch, and the toe supporting portion of the toe ball and the small toe supporting the foot has a thickness in front of the toe supporting portion The front part of the insole that is thinner than the toe ball support.

According to the present invention, the toe ball supporting portion supports the ball of the big toe and the small toe of the foot in a state where the anterior calcaneal supporting convex portion maintains the medial longitudinal arch, lateral longitudinal arch and lateral arch of the foot. The toes in front of the first to fifth basal bones of the foot are kept unconstrained while maintaining the arch of the foot. Therefore, when walking or traveling, the toes are free while the arch of the foot is maintained, so that the walking motion of grasping the ground with the toes can be realized.

Furthermore, according to the present invention, since the thickness of the front portion of the insole is thinner than the toe ball support portion, the degree of freedom of the toes is further improved, a walking action such as grasping the ground with toes can be easily performed, and the exercise effect can be improved .

According to the present invention, the arch shape of the sole of the foot can be maintained to ensure the stability and sportiness of the body, and at the same time, it can easily perform the action of grasping the ground with the toes to improve the athletic effect.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The diagram of this embodiment shows the left and right insole 1 and the skeleton of the foot. The insole 1 of the other side and the skeleton of the foot form a mirror image object.

Fig. 1 is a perspective view of the insole 1 of the present embodiment.

The shoe insole (insole for shoes) 1 is provided with a shoe insole body 160. The shoe insole body 160 is shaped like an inner contour of a shoe when viewed from a plane angle, and has an outer edge contour 70 stored inside the shoe. By making the outer edge contour 70 conform to the inner contour of the shoe, when the insole 1 is inserted, the insole 1 can be installed in a predetermined position in the shoe. The shape of the foot of the person using the insole 1 varies from person to person and is not fixed, so the overall size of the insole 1 can be selected according to the size of the user's foot.

FIG. 2 is a bottom view of the insole 1 with bones of the foot superimposed. This diagram is a diagram viewed from below. Since the bones overlap each other, please note that part of the bones is not visible. The plan view viewed from the front of the foot is different from the bottom view of FIG. 2 in that the bones are superimposed in a different manner.

As shown in Fig. 2, the skeletal structure 10 of the foot is composed of calcaneus 12, talus 14, scaphoid 16, dice bone 18, first to third wedge-shaped bones 20, 22, 24, and first to fifth metatarsal bones 26, 28, 30, 32, 34, 1st to 5th ganglion bones 36, 38, 40, 42, 44, 2nd to 5th medullary bones 46, 48, 50, 52, and 1st to 5th The end bones 54, 56, 58, 60, 62 are formed. The front ends of the first to fifth metatarsals 26, 28, 30, 32, and 34 are the first to fifth metatarsal heads 26A (also known as the ball of the hallux ball 26A), 28A, 30A, 32A, 34A (also known as the small Toe ball 34A). The segment-like portion located at the front of the calcaneus 12 is the front of the calcaneus (also called calcaneal tuberosity) 12A. In addition, in the second figure, only the portions of the scaphoid bone 16 that cannot be seen because the bones overlap each other are indicated by broken lines.

In this structure, as shown in FIGS. 1 and 2, the surface (upper surface) 1A of the insole body 160 is formed with a dice bone supporting convex portion 80 and a front calcaneal supporting convex portion 90 constituting the convex portion 2. . The dice bone supporting convex portion 80 is provided at a portion corresponding to the dice bone 18, and the calcaneus front supporting convex portion 90 is provided at a portion corresponding to the calcaneus nodule 12A. The middle of the dice bone supporting convex portion 80 and the front calcaneal supporting convex portion 90 is solid.

The anterior calcaneus support convex portion 90 is provided above the dice bone supporting convex portion 80. The surface of the anterior calcaneal support convex portion 90 overlaps with the surface of the dice bone supporting convex portion 80 to form a convex portion 2. The dice bone supporting convex portion 80 and the calcaneus front supporting convex portion 90 may be integrated with each other, or may be separate individuals, or may sometimes form different individuals from the flat shoe insole. In addition, the anterior calcaneus support convex part 90 in FIG. 2 is shown by a schematic diagram with a contour line showing the height of the anterior calcaneal support convex part 90.

On the inner surface (lower surface) 1B of the insole body 160, there are formed the toes of the first metatarsal head (bunny ball) 26A and the second to fifth metatarsal heads (small toe ball) 28A to 34A for supporting the foot A ball supporting portion (hereinafter referred to as a bulging portion) 100. The bulging portion 100 bulges downward from the inner surface (lower surface) 1B of the insole body 160. The bulging portion 100 is such that the front edge portion extends from a line connecting the first basal bone 36 to the fifth basal bone 44 when viewed from the bottom. An insole front portion 110 of the insole body 160 is formed in front of the bulging portion 100, and the thickness of the insole front portion 110 is thinner than the thickness of the bulging portion 100.

FIG. 3 is a transverse sectional view of the insole 1 and FIG. 4 is a longitudinal sectional view of the insole 1. In addition, in Figures 3 and 4, (S0-S0) to (S7-S7), (S10-S10) to (S14-S14) and (S0-S0) to (S7- S7), (S10-S10) to (S14-S14) correspond.

The S0-S0 cross-section is a cross-section that crosses the vicinity of the first end bone 54 and the second to third middle bones 46, 48, and the insole body 160 in this section, that is, the insole front 110 is flat.

The S1-S1 cross-section is a cross-section that crosses the vicinity of the first to fourth base bones 36 to 42 and the fifth end bone 62, and the bulging portion 100 is provided on the inner surface 1B of the insole body 160.

The bulging portion 100 is formed with a toe ball portion 103 for supporting the ball of the ball of the toe 26A, and a toe ball portion 104 supporting the second to fourth metatarsal heads 28A to 32A and the small toe ball 34A. A V-shaped recess 105 is formed between the ball portion 103 and the other ball portion 104. The thickness of the outer peripheral portion 102 is inclined upward so as to gradually decrease toward the outside of the bulging portion 100.

The S2-S2 section is a section that crosses the first metatarsal head 26A and the fifth metatarsal head 34A. This part of the insole body 160 is provided with a flat surface portion 100A on the surface 1A and a bulging portion 100 bulging downward on the inner surface 1B. The bulging portion 100 includes a flat body portion 101 and an outer peripheral portion 102 of decreasing thickness.

The S3-S3 section is a section that crosses the metatarsals 26 to 34. This part of the insole body 160 is provided with a flat surface portion 100A on the surface 1A and a bulging portion 100 on the inner surface 1B. At the rear edge portion of the bulging portion 100, an arc-shaped recessed portion 106 is formed in which the central portion in the width direction is recessed toward the front in an arc shape when viewed from the angle of the bottom surface.

The S4-S4 profile is equivalent to the transverse arch of the metatarsal bones 26 to 34, and the insole body 160 corresponds to the general foot. Its thickness is thicker than the part that does not step on the ground, and the surface The side leans down towards the outside of the right foot and the thickness gradually decreases. In addition, on the inner surfaces of the left and right inner and outer sides, thickness cut-out portions 72 and 74 are formed on both sides of the flat portion, and slight deformation toward the left and right in the cross section of S4-S4 is allowed.

The S5-S5 cross-section is a portion corresponding to the dice bone 18, and the insole body 160 is provided with a dice bone supporting convex portion 80 having a maximum thickness. The surface 80A of the dice bone supporting convex portion 80 slopes downward from the portion corresponding to the dice bone 18 toward the left and right side edges 76, including the portion 3 corresponding to the scaphoid 16 (FIG. 2 ), and gradually decreases in thickness. The insole body 160 is attached to the S5-S5 cross section, and has a raised edge 78 at the outermost edge.

The S6-S6 section is a cross section of the calcaneal tuberosity 12A, and is equivalent to the end point of the longitudinal posterior arch of the foot. This part of the insole body 160 has the maximum thickness of the calcaneal anterior supporting convex portion 90, and its surface 90A is from the portion corresponding to the calcaneal tuberosity 12A toward the left and right side edges 76, and includes the equivalent to the scaphoid 16 Site 3 (Figure 2) slopes down to gradually decrease the thickness.

The S7-S7 section is a cross section of the posterior part of the calcaneus 12 and corresponds to the end point of the posterior longitudinal arch. The insole body 160 corresponds to a general foot. In order to support the heel, the surface 1A side is relatively flat. In addition, the insole body 160 faces both sides, and the surface 1A side is inclined upward to gradually increase the thickness, and a raised edge portion 78 is provided on the outermost edge. Thickness-removed portions 72 and 74 are formed on the inner surfaces of the left and right inner and outer sides, allowing slight deformation toward the left and right in the S7-S7 cross section.

The S10-S10 cross-section and the S11-S11 cross-section correspond to the cuneiform bones 20 to 24 and the scaphoid 16 that constitute the medial longitudinal arch, and the surface is raised.

The insole 1 of the present invention does not only support the portion corresponding to the dice bone 18 and the calcaneal tuberosity 12A, but also supports other parts in consideration of stability. However, it is not a structure that restricts the movement of the foot. Therefore, in this section, the insole body 160 is provided with the thickness cut-out portion 72 and can sink inside the dice bone supporting convex portion 80. Therefore, even when a force is applied to the portions corresponding to the wedge-shaped bones 20 to 24 and the scaphoid bone 16, the insole body 160 is deformed by the thickness cut-out portion 72 and the stress is relieved.

The cross sections S11-S11 to S13-S13 are portions corresponding to the dice bones 18, and are provided with dice bone supporting convex portions 80 of maximum thickness. The surface 80A of the dice bone supporting convex portion 80 is inclined downward from the portion corresponding to the dice bone 18 toward the front and back, so that the thickness gradually decreases. In other words, when the foot is placed inside the shoe with the insole 1 installed and a standing posture is formed, the dice bone supporting convex portion 80 equivalent to the dice bone 18 exerts the maximum stress on the inner surface of the foot. The insole 1 is a structure in which the stress is gradually relaxed and gradually decreased from the front and back of the dice bone supporting convex portion 80.

In addition, as a structure on the bottom surface side of the insole 1, the portion that contacts the shoe is flat at the portion corresponding to the dice bone 18, that is, inside the dice bone supporting convex portion 80. With this configuration, a reaction force often acts on the dice bone 18 from the shoe.

The S12-S12 cross-section and the S13-S13 cross-section are also parts corresponding to the calcaneal tuberosity 12A, and have a maximum thickness calcaneal anterior support convex portion 90. The surface 90A of the anterior calcaneus support convex portion 90 is inclined downward from the portion corresponding to the calcaneus nodule 12A toward the front and back, so that the thickness gradually decreases. In other words, the insole 1 has a structure in which the stress is gradually relieved and gradually decreased from the front support protrusion 90 of the calcaneus to the front and rear. In addition, the part in contact with the shoe is flat at the part corresponding to the calcaneus nodule 12A, that is, on the inner side of the support convex part 90 at the front of the calcaneus. With this structure, a reaction force often acts on the calcaneal tuberosity 12A from the shoe.

The S14-S14 cross-section is at a position corresponding to the fifth metatarsal bone 34 that constitutes the lateral longitudinal foot arch, and the surface is raised.

This part is located outside the dice bone supporting convex portion 80 and the calcaneus front supporting convex portion 90, and has a slight bulge in consideration of stability. However, it is not a structure that restricts the movement of the foot. A thickness-removed portion 74 is provided at a portion corresponding to the lateral longitudinal arch of the lateral foot, and the insole 1 is attached to the outside of the dice bone supporting convex portion 80 and the anterior calcaneal supporting convex portion 90 to sink. Even when the fifth metatarsal 34 of the lateral longitudinal arch is strongly applied, the insole body 160 deforms due to the thickness cut-out portion 74 and relaxes the stress.

In this structure, when the insole 1 is installed, the dice bone 18 is supported with the dice bone supporting convex portion 80 as the apex. Since the dice bone 18 is supported from below, the foot can maintain the neutral position toward the left, right, front, and back, while using the dice bone 18 as a support point to allow valgus movement in the internal rotation movement, and allow valgus movement in the external rotation movement.

As a result, the insole 1 will not hinder the normal movement of the joint, and it is not necessary to compensate with other parts, and the movement to the center of gravity of the front, back, left, and right becomes easy. That is, the insole 1 is not fixedly restricted as if the foot is covered with gypsum, but the surface is tilted from the dice bone supporting convex portion 80 in the radial direction to ease the stress, and then the thickness cut-out portion 72 is provided by providing the thickness 74 and the insole 1 itself is easily deformed to allow movement. The insole 1 will be shaped to support the corresponding portion of the dice bone 18 from below, while correcting and preventing excessive skew of the bones of the foot, while smoothly guiding the internal rotation and external rotation.

Figure 5 shows the arch of the sole of the foot.

When a person's sole is walking or traveling, as long as it is in a natural state, a foot arch (shown in dashed line mode) 119 is formed.

The arch 119 includes a medial longitudinal arch 121 and a lateral longitudinal arch 122 formed toward the long side of the foot, and a lateral arch 120 formed toward the short side of the foot. As shown in FIG. 2, the lateral foot arch 120 is formed across the first to fifth metatarsals 26 to 34. In addition, the medial longitudinal foot arch 121 is formed across the calcaneus 12, the talus 14, the scaphoid 16, the three wedge-shaped bones 20 to 24, and the first to third metatarsals 26 to 30. The lateral longitudinal foot arch 122 is formed across the calcaneus 12, the dice bone 18, and the fourth to fifth metatarsals 32, 34.

FIG. 6 is a schematic diagram illustrating the principle that the weight F of the user acts on the calcaneus 12 from the tibia 68 via the talus 14 when the insole 1 is installed.

The calcaneus 12 is an important part that supports the weight F of the user. The anterior end 12B of the calcaneus 12 of the calcaneus 12 forms a force application point P1, and the lower end of the calcaneus (rear portion of the calcaneus) 12C forms a support point P2. Therefore, the calcaneus 12 has a moment effect centering on the support point P2.

In this structure, the calcaneus 12 can be stabilized by the calcaneal tuberosity 12A substantially directly below the force point P1 supported by the anterior calcaneus support protrusion 90. In addition, the calcaneal tuberosity 12A is at a distance from the lower end 12C of the calcaneus forming the support point P2. Therefore, by providing the front calcaneal support convex portion 90 at a location corresponding to the calcaneal tuberosity 12A, a small force can effectively be used Support calcaneus 12.

The dice bone 18 also has the user's weight F acting through the calcaneus 12. Regarding the dice bone 18, since the first to fifth metatarsal heads 26A to 34A form a support point P3, the dice bone 1 has a moment effect centering on the support point P3.

In this structure, the dice bone 18 can be stabilized by supporting the dice bone 18 directly below the force point P1 with the dice bone supporting convex portion 90.

In addition, the dice bone 18 is at a distance from the first to fifth metatarsal heads 26A to 34A forming the support point P3. Therefore, by providing the dice bone support convex portion 80 at a position corresponding to the dice bone 18, a smaller The force effectively supports the dice bone 18.

However, just by supporting the dice bone 18, sometimes the calcaneus 12 is not easily stabilized, and skew may occur in the dice bone 18 and the calcaneus 12 and the joint (the calcaneus joint).

Since the calcaneus 12 simultaneously constitutes both the medial longitudinal arch 121 and the lateral longitudinal arch 122, if the calcaneus 12 is unstable, it is not easy to maintain the longitudinal arch in a normal position. In particular, the calcaneus nodule 12A at the front of the calcaneus 12 is located at the place where the midfoot portion of the calcaneus 12 overlaps the long plantar ligament 64 connecting the second to fifth metatarsals 28 to 34 as shown in FIG. 6. The long plantar ligament 64 also has the function of maintaining the longitudinal arch of the foot.

In this configuration, the anterior calcaneus support convex portion 90 supports the calcaneal tuberosity 12A via the long plantar ligament 64, so the calcaneus 12 is stable, the calcaneus joint deflection can be reduced, and the longitudinal foot arch can be placed in a normal position. With this, the longitudinal arch can effectively function as a spring. In particular, at night, the function of the long plantar ligament 64 to maintain the longitudinal arch of the foot is reduced compared to the daytime. Therefore, the support of the long plantar ligament 64 is effective. The anterior calcaneus support protrusion 90 includes the portion 4 of the calcaneus nodule 12A corresponding to the position where the long plantar ligament 64 overlaps.

The anterior calcaneal support projection 90 is not just supporting the long plantar ligament 64 to promote passive stabilization of the arch, but the long plantar ligament 64 supports the peroneus longus which is very important for the active stabilization of the lateral longitudinal arch Stop tendon 66. Here, passive stabilization is done by ligaments, and active stabilization is done by muscles (tendons). The stopping tendon 66 of the peroneus longus is wound around the dice bone 18 as shown in Figure 2, and the sole of the foot is transversely cut from the lateral edge of the foot and stopped at the first wedge bone 20 and the first metatarsal bone 26 bottom. Furthermore, a part of the front supporting protrusion 90 of the calcaneus is located at the lower part of the dice bone 18, and the scaphoid 16 is supported via the dice bone 18. As a result, the stop tendon 67 of the posterior tibial muscle, which is the main active stabilizing structure of the medial longitudinal foot arch, is indirectly supported.

The stopping tendon 67 of the posterior tibial muscle exposes the fascia to the first to third cuneiform bones 20 to 24, the second to third metatarsal bones 28, 30, and the scaphoid bone 16. With the oblique direction of the two muscles of the fibula longus and the posterior tibia, the longitudinal arch can be maintained in addition to the lateral arch.

In addition, since the calcaneus 12 also constitutes a joint, only a fixed support will hinder the exercise function, so movement must also be allowed.

The insole body 160 has a structure in which the dice bone supporting convex portion 80 is the center and the surface is tilted downward in the radial direction to relax the stress, so that the movement of the joint composed of the calcaneus 12 can be allowed. More specifically, the front supporting protrusion 90 of the calcaneus is formed of a relatively soft material. Due to the weight of the user, the thickest part will sink and support the calcaneus nodule 12A. With the sinking of the front supporting protrusion 90 of the calcaneus, the insole 1 is inclined downward in the radial direction of the front, back, left, and right with the dice bone supporting protrusion 80 as the center, and the foot is supported with the dice bone 18 as the supporting point, and This dice bone supports the movement of the foot centered on the convex portion 80.

In this configuration, the anterior calcaneal support convex portion 90 will abut the calcaneal tuberosity (the anterior heel of the foot) 12A, and maintain the medial longitudinal arch 121, lateral longitudinal arch 122, and lateral arch 120 of the foot.

The calcaneus 12 can be stably supported by the front supporting protrusion 90 of the calcaneus, the lateral arch 120, the medial longitudinal arch 121, and the lateral longitudinal arch 122 of the sole can maintain a natural shape, so that the foot is stable and athletic Promote.

In addition, in this state, in which the anterior calcaneus support convex portion 90 maintains the medial longitudinal arch 121, lateral longitudinal arch 122, and lateral arch 120, the bulging portion 100 supports the first Metatarsal head (bunion ball) 26A, 2nd to 5th metatarsal head (small toe ball) 28A to 34A.

This structure is as shown in FIG. 6, the surface part 100A of the bulging part 100 is held above by the bulging part 100 contacting the midsole 7 of the shoe, and the surface part 100A, the ball of the big toe 26A or the little toe The first to fifth metatarsal heads 26A to 34A of the ball 34A, etc., that is, the root side of the toes are held upward.

Therefore, a state in which the toe of the calcaneus anterior supporting convex portion 90 is maintained while the arch of the foot is maintained is not restricted.

In general, the midsole of the shoe raises the heel side and lowers the toe side to facilitate walking, but because the toe side is lower, the force is easily applied to the toe side when applying weight, so that all the toes are easy Butt to the midsole 7 of the shoe. Therefore, sometimes the toes are not easy to move and hinder the natural movement of the toes, and the toes are not easy to get natural movement stimulation.

In contrast, in this structure, the bulging portion 100 holds the ball of the big toe 26A and the ball of small toe 34A at a higher position relative to the midsole 7 of the shoe, and thus is supported by the foot system of the insole 1 It is easy to approach the level in shoes, and the weight is not easily applied to the tip of the toe on the front side of the support point P3 (refer to FIG. 6), and the toes are easily moved.

The insole body 160 in this structure is provided with a calcaneus front support convex portion 90. Therefore, the user of the insole 1 wears the soles 120 to 122 in a state where the arches 120 to 122 can maintain a natural shape, the toe side becomes higher, and when walking or traveling, the toes naturally grasp the ground and easily move. Therefore, when going uphill or going up and down stairs, the force is easily applied to the side of the toes, and the toes are easy to get ideal sports stimulation. By using the shoe insole 1 of this structure, the decrease in the body function of the foot is easily suppressed.

Toe training can be performed as long as the shoes with the insole 1 of this structure installed are worn for walking. In particular, in this structure, since the insole 1 is also provided with the dice bone supporting convex portion 80, the skeleton of the foot is adjusted in a balanced manner, the stability and luck are more improved, and training is easier.

The thickness of the front portion 110 of the insole in this configuration is thinner than the bulging portion 100, so the freedom of the toes in front of the first to fifth end bones 54 to 62 of the foot is further improved.

The action of the toes grasping the ground is based on the base joint bones 36 to 44, middle joint bones 46 to 52 and terminal joint bones 54 to 62 in the second figure, the so-called toe placement of the insole front 110 is more than the ball 26A It is easy to perform when the bulging portion 100 where the little toe ball 34A is placed is softer.

The thickness of the front portion 110 of the insole in this embodiment is thinner than the bulging portion 100 and is relatively soft, so that the toes can be easily moved.

Therefore, the walking action of grasping the ground with toes can be easily performed, and the exercise effect can be improved. The shape of the arch of the foot can be maintained to ensure the stability and sportiness of the body, and at the same time improve the exercise effect.

In this configuration, since the bulging portion 100 is formed on the inner surface 1B, as shown in FIG. 6, a gap 111 is generated between the approaching portion of the bulging portion 100 and the midsole 7 of the shoe. Therefore, it is easy to press the insole front portion 110 of the insole 1 from above toward the gap 111. In addition, a V-shaped concave portion 105 is also formed in the bulging portion 100, and the thickness between the ball 103 and the ball 104 is thinner, so that it is easy to push the insole front 110 toward the gap 111 with the ball.

In this way, in this embodiment, it becomes easy to bend the toes, and it is easy to apply force to the toes, so that the action of grasping the ground with the toes is easily performed.

In addition, the bulging portion 100 is in contact with the sole of the foot with the flat surface portion 100A, so it is less likely to hinder the movement of the foot than in the case of being in contact with the sole of the foot in a concave-convex shape.

On the other hand, since it is not easy to hinder the movement of the foot, while walking or exercising, although the positions of the ball 26A or the ball 34A may be shifted, the bulging portion 100 is formed broadly in the front-rear direction. The bulging portion 100 can support the big toe ball 26A and the small toe ball 34A.

As described above, the insole 1 for shoes of the present embodiment includes: a heel that abuts on the anterior calcaneus 12A of the foot to maintain the medial longitudinal arch 121, lateral longitudinal arch 122, and lateral arch 120 of the foot The anterior bone supporting convex portion 90; and the toe ball 26A for supporting the foot while the anterior calcaneal supporting convex portion 90 maintains the medial longitudinal arch 121, lateral longitudinal arch 122 and lateral arch 120 The bulging portion 100 of the little toe 34A is provided with a front portion 110 of the insole having a thinner thickness than the bulging portion 100 in front of the bulging portion 100. Therefore, the shape of the arches 120 to 122 of the sole of the foot can be maintained in a natural state to ensure the stability and motility of the body, and at the same time, the action of grasping the ground with the toes can be easily performed and the toes can be trained.

In the present embodiment, the surface 1A is flat from the front part 110 of the insole to the bulging part 100, and the bulging part 100 bulges downward. Therefore, the bulging portion 100 is in contact with the midsole 7 of the shoe, and the surface portion 100A forming the surface 1A of the bulging portion 100 is in contact with the sole of the foot with a flat surface, so the toes can be easily moved.

In this embodiment, the front edge of the bulged portion 100 extends on the line connecting the first base bone 36 to the fifth base bone 44 of the foot, and the first base bone 36 and the second base bone 38 A V-shaped recess 105 is formed in the front edge portion between them, and is recessed toward the rear. Therefore, the toe, that is, the insole 1 corresponding to the portions of the first base bone 36 and the first end bone 54 can be easily pushed downward, and the action of grasping the ground with the big toe can be easily performed .

In this embodiment, an arc-shaped concave portion 106 is formed in the rear edge portion of the bulging portion 100, and the central portion in the width direction is concave toward the front. Therefore, it is not easy to make the sole of the foot feel the boundary of the bulging portion 100 and the uncomfortable feeling can be reduced.

Moreover, in this embodiment, the thickness of the outer peripheral portion of the bulging portion 100 gradually decreases. Therefore, the outer peripheral portion 102 of the bulging portion 100 can be slowly deformed according to the weight, so that the discomfort to the feet can be reduced.

Furthermore, in this embodiment, a dice bone supporting convex portion 80 is arranged to overlap the anterior calcaneus supporting convex portion 90, and the dice bone supporting convex portion 80 includes a portion corresponding to the scaphoid bone 16 from the dice bone 18 of the foot. The thickness is gradually decreased toward the left and right side edges, and the thickness is gradually decreased from the position corresponding to the dice bone 18 toward the front and rear, and the thickness is gradually decreased toward the radial directions of the front, rear, left, and right. Therefore, since the dice bone supporting convex portion 80 is provided, the dice bone 18 and the calcaneus are maintained while the arch shape of the calcaneus joint including the dice bone 18 and the calcaneus 12 is maintained, and the motion of the foot is allowed. 12 is stable, so the skewness of the heel joint is reduced, and the entire heel bone including the dice bone 18 and the heel bone 12 is stabilized in a natural state. As a result, the joints of the foot can move freely, so the function of the foot can be improved.

However, the above-mentioned embodiment is only the same state as the present invention, and can of course be changed as appropriate without departing from the gist of the present invention.

For example, in the above-described embodiment, the insole body 160 is integrally formed, but other convex portions 2 or bulging portions 100 may be detachably attached to the flat insole material. In addition, by forming the insole body 160 as a plurality of layers and attaching the convex portion 2 and the bulging portion 100 to the intermediate layer, irregularities can be formed on the surface material.

Although the dice bone supporting convex portion 80, the calcaneus front supporting convex portion 90, and the bulging portion 100 are formed to be solid, the dice bone supporting convex portion 80, the calcaneus front supporting convex portion 90, and the bulging portion 100 may also be formed The inside of the surfaces 80A, 90A, 101 is formed to be hollow.

The purpose of the shoe insole of the present invention is to improve the improvement of standing posture and the improvement of sports function. In addition to being used as a daily shoe, it is also suitable for widely used in sports shoes that pursue functionality, such as skiing or football, or Various shoes such as medical shoes for the purpose of treatment or rehabilitation, training shoes for the purpose of improving health.
