According to the present invention, it is possible to obtain shoe correction parts and shoes that enable movement under load such as walking movement or running movement with correct alleles.

It is explanatory drawing which shows the movement of the shoe and the right foot under no load, and the movement of the shoe and the right foot when overpronation occurs under load. It is explanatory drawing which shows how the overpronation is reduced by attaching the shoe correction part and the shoe correction part of this embodiment to a shoe. It is a figure which shows the state which the shoe correction part of this embodiment is attached to the shoe.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory diagram showing the movement of the shoe and the right foot when the load is not applied and when the load is overpronation. FIG. 2 is an explanatory diagram showing how the shoe correction component and the shoe correction component of the present embodiment are attached to the shoe to reduce overpronation. FIG. 3 is a diagram showing how the shoe correction component of the present embodiment is attached to the shoe. Although the shoes and shoe correction parts corresponding to the right foot are described in FIGS. 1 to 3, the shoes and shoe correction parts corresponding to the left foot are substantially line-symmetric with respect to the shoes and shoe correction parts corresponding to the right foot. Since the shape, function, action, and material are the same as those of shoes and shoe correction parts corresponding to the right foot, the description thereof will be omitted.
In addition, when there is no load, the state where the foot is off the ground, and when there is a load, the body weight is applied to the foot that is in contact with the ground, such as when standing, walking, or running, and the body weight is applied from the ground. The state of receiving the reaction force of.

When walking or running, if the movement of a series of functions is not performed in the correct alignment, symptoms such as foot pain, low back pain, knee pain, shin splints, callus, or bean may occur. In order to improve such symptoms, it is required to reduce excessive pronation (overpronation), which is a major cause of symptoms caused by walking and running. The pronation itself acts as a cushion for the floor reaction force and shock absorption when the foot touches the floor, but when overpronation is performed, it causes various obstacles.

On the left side of FIG. 1, a cross-sectional view showing the movement of the shoe and the right foot under no load is shown, and on the right side of FIG. 1, a cross-sectional view showing the movement of the shoe and the right foot under load with overpronation is shown. It is shown. Section 1-1', section 2-2', section 3-3', section 4-4' in FIG. 1 are cut lines 1-1', cutting lines 2-2', in the top view of the foot in FIG. It corresponds to the cross section of the cutting line 3-3'and the cutting line 4-4', respectively.
At the time of no load shown on the left side of FIG. 1, there is a space between the foot 30 and the shoe 20 as shown on the inside of the shoe 20 (left side in the figure). Under the load where the overpronation shown on the right side of FIG. 1 occurs, the foot 30 and the shoe 20 under no load are deformed like the foot 30a and the shoe 20a.

The shoe correction component of the present embodiment is designed to reduce overpronation, maintain correct foot alignment, and propel forward. Walking or running with the correct foot alignment by the shoe correction component of the present embodiment reduces the burden on the foot and the stress of a specific part.
As shown in FIG. 2, in the shoe correction component 10 of the present embodiment, the portion directly below the heel portion of the foot is opened in an arc shape by the opening OP. Overpronation occurs when the joints of the foot move excessively in the diagonal direction under a load such as when walking or running, as shown in the cross-sectional view on the right side of FIG. Focusing on the fact that overpronation is unlikely to occur directly under the heel of the foot in contact with the bottom of the shoe, in this embodiment, the opening OP is opened so as to be opened in a bow shape along the heel of the foot in the shoe. Is provided. The opening OP serves as a reference for alignment when the shoe correction component is attached to the shoe, and as shown in FIG. 3, the shoe correction component 10 is attached to the shoe 20 so that the opening OP is arranged on the heel of the foot. match.

As shown in FIG. 2, the shoe correction component 10 has a bow-shaped side surface and a bow-shaped vertical cross section. The vertical cross section may be crescent-shaped. The convex curved surface side of the shoe correction component 10 is the side to be bonded from the side wall portion in the inner direction of the shoe 20 to the bottom portion (bottom surface). The vertical cross section has a bow shape or a crescent shape because, as shown on the left side of FIG. 2, the shoe correction component 10 has a shape that can be easily arranged in the space between the shoe 20 and the foot 30.

Further, the shoe correction component 10 of the present embodiment has a width in which the portion excluding the peripheral portion of the opening OP is provided in the region from the side wall portion in the inner direction of the shoe 20 to the center line of the shoe 20 at the bottom. Then, a portion of the shoe correction component 10 excluding the peripheral portion of the opening OP is provided in the region from the side wall portion in the inner direction of the shoe 20 to the center line of the shoe 20 at the bottom. By arranging the shoe correction component 10 in such a region, the shoe correction component 10 can be arranged at a position where the overpronation shown on the right side of FIG. 1 can be effectively suppressed. The center line of the shoe is the line connecting the center of the maximum width of the shoe and the end of the heel of the shoe. In FIG. 2, the center of the shoe is the center of the second toe of the foot and the end of the heel of the foot. Corresponds to the line connecting with.

At the time of no load shown on the left side of FIG. 1, there is a space between the foot 30 and the shoe 20 as shown on the inside of the shoe 20 (left side in the figure). Under the load where the overpronation shown on the right side of FIG. 1 occurs, the foot 30 and the shoe 20 under no load are deformed like the foot 30a and the shoe 20a. At this time, the force applied to the foot is diagonally downward on the inside as shown by the arrow on the right side of FIG. Therefore, in order to suppress overpronation, the shoe correction component 10 may not be arranged outside the center line seen from above the shoe, but may be arranged inside from the center line of the shoe.
In the present embodiment, as shown on the left side of FIG. 2, by arranging the shoe correction component 10 inside from the center line of the shoe, overpronation under load such as walking or running is suppressed.

The specific shape and thickness of the shoe correction component 10 not only considers the relationship between the load of walking or running and the sole of the foot, but also considers the balance of the entire body of each person, and the shoe that the person wears. It is decided in consideration of the relationship. It is tailored to the shoe used by the patient, taking into account the shape of the patient's foot and the movement under load of walking or running to assist the entire body from the foot.

Installation of the shoe correction component 10 on the shoe is a three-dimensional component inside the shoe from the end of the heel of the foot (A in FIG. 2) to the head of the first phalange (B in FIG. 2). This is done by adding the correction component 10. The maximum length of the shoe correction component 10 is the length from the end of the heel of the foot in the shoe 20 (A in FIG. 2) to the head of the first phalange of the foot (B in FIG. 2). Naturally, it is created and attached according to the size and shape of the left foot and right foot and the shape of the shoes to be worn. In addition, it will be adjusted and installed each time according to the improvement of the walking motion under load. As a result, the foot adjustment effect is improved and the walking alignment is more stable than ever. It is also effective in improving the normal development and adulthood of the feet of growing children, solving problems caused by shoes in the middle of life, improving athletic ability during sports, and improving gait disorders such as ankles, knees and hip joints of the elderly. can.

Foamed plastic can be used as the material of the shoe correction component 10, and in particular, it is deformed to some extent by compression with the foot due to walking under load, but it is hardened by the temperature change inside the shoe and used for a long period of time. It is desirable that the shape can be maintained. Examples include polyolefin-based foamed plastics, polyurethane foams, and EVA sponges.

The shoe correction component 10 is manufactured as follows and is attached to the shoe.
A plurality of types of basic shapes of the shoe correction component 10 are prepared according to the foot size classification and the shoe shape type. A plurality of basic shapes of the shoe correction component 10 are prepared according to the A_B value shown in FIG. 2, the value of the width W1 + W2, and the thickness t. The width W1 is ½ of the sole width, and the width W2 is basically the same as the width W1, but it is adjusted by the height of the inner side surface of the shoe (the height from the bottom surface of the shoe). Here, A in FIG. 2 is the position of the end of the heel of the foot and the position of the end of the shoe correction component 10 on the heel side, and B is the position of the head of the first middle toe bone of the foot and the heel side of the shoe correction component 10. The position of the end opposite to the above, C is the position of the lower end c of the boat-shaped bone and the position Cc of the shoe correction part 10, D is the position of the lower end d of the wedge bone and the position Dd of the shoe correction part 10, E is the heel bone. The position of the lower end e of the tip of the foot, the position Ee of the shoe correction component 10, and F indicate the position of the lower end f at the center of the first middle toe bone and the position Ff of the shoe correction component 10.

Next, the practitioner and the prescriber measure the patient's foot and obtain the A_B value, the A_C value, the A_D value, and the A_E value, which are the lengths shown in FIG. Next, the thickness t and the width W2 of the shoe correction component 10 are selected from the situation of overpronation under load due to walking and the shape of the shoe to be used.
From these data, a prescription is created, and the basic shape of the shoe correction component 10 is selected from the prepared basic shapes of the shoe correction component 10. The shoe correction component 10 suitable for the patient is created by cutting from the basic shape of the selected shoe correction component 10.
Adhesive is applied or a hook-and-loop fastener is applied to the curved surface (back surface) side of the finished shoe correction component 10 specified for the individual.

The shoe correction component 10 is attached with the curved surface (back surface) side along the inner wall of the shoe. The shoe correction component 10 is attached to the shoe so that the center line of the shoe correction component 10 is along the ridge line where the bottom surface of the shoe correction component 10 is in contact with the side wall surface, with the shape of the heel portion as a reference. By doing so, the space between the shape of the shoe and the foot is filled, and the foot conditioning effect is exhibited. After using the shoe with the shoe correction component 10 for several months, it will become familiar to the foot and the walking alignment will be stable.

The shoe correction component 10 attached in a detachable state with a hook-and-loop fastener or the like can be attached to another shoe of the same type by contacting the hook-and-loop fastener or the like when the shape becomes stable. The shoe correction component 10 identifies an individual's foot and shoe, is prescribed, and is produced and installed inside the specific shoe. However, by attaching it to the inner foot side surface and the sole surface of the shoe using a hook-and-loop fastener or the like, the shape of the shoe correction component 10 becomes familiar with the foot and the shoe after a certain period of time, and then another shoe of the same type is used. It can be reused by the same pasting method.

It is also possible to combine a general and different function flat insole (insole) with the shoe correction component 10 to create a type that can be replaced when the shoe is replaced.
According to the shoe correction component 10 of the present embodiment described above, it is possible to appropriately cope with the movement that affects the medial part of the foot and the sole of the foot due to the walking movement under load, and the structure of the ready-made shoe and each patient can be adjusted. It can also handle differences in individual foot shapes and motor functions.
