Abstract

To solve problems of footwear for foot deformity disorder, the problems in which commercially available ready-made footwear has an insole designed on the average data of human foot and naturally it is a difficult task to find ready-made footwear that fits individual user's foot, in which, particularly a user having a lesion in the foot often experiences pain in footwear with no footwear available that has effect for correcting a lesion, and in which although custom-made footwear is better than ready-made footwear in the fidelity of the last, there is no remedial effect at all for a foot having a lesion.SOLUTION: Projection is made for the sole of a user in a total of five parts which are in addition to three parts in Fig. 2 for the ball of a big toe 9, the balls of other toes 10, and a heel 11, and two parts for a big toe 8 and a little toe 7. As shown in Fig. 1, the five parts of the marks 2, 3, 4, 5, 6 are notched or drilled, and the insole 1 in which each part is fit in the inner sole of the footwear is spread on the inner sole of the footwear, otherwise the insole 1 is fabricated into the inner sole of the piece of footwear to make an integrated structure.SELECTED DRAWING: Figure 1

Description

There is an application for exception to loss of novelty

An insole that is laid on the inner sole of footwear and has a thickness ranging from 1 mm to about 20 mm depending on the use of the footwear. Cut out a portion projected on the sole of the user's foot for a total of 5 points, including the ball of the big toe, the ball of the little toe, and the heel, and 2 points of the big toe and little toe, and place it in the footwear, or The structure of the footwear is changed to notches and five places of the insole are made concave. As a result, the five parts of the sole of the foot are dropped into the insole of the footwear, and the medial longitudinal arch of the foot that connects the ball of the foot and the heel, the lateral longitudinal arch of the foot that connects the ball of the little toe and the heel, and the toe. A horizontal arch of the foot is formed that connects the ball and the ball of the foot. An arch formed by these three dips is generally called a three-point arch.

Furthermore, by adding the drop of the thumb and little toe, which is the core of the present invention, the toe has a margin corresponding to the thickness of the insole, and the finger thrust is reduced. Due to the synergistic effect of the 3-point arch and the horizontal arch mentioned above, the balance of the center of gravity of the sole becomes correct, and the big toe turns inversion. As a result, the pain of the bunion is alleviated while being corrected and healed, or the onset of the bunion is prevented. Similarly, the position of the little toe, which has been depressed in five places, can be corrected to the valgus side while reducing the pain of the little toe, thereby obtaining a healing or prevention effect.

In addition to the effect of correcting foot deformity, the present invention enhances the gripping force of the sole on the insole of footwear to maintain a stable and beautiful walking and running posture. This effect reduces the fatigue of the feet (legs) of people engaged in standing work, and contributes to the improvement of the feeling of wearing all footwear, such as the improvement of the ability of the lower limbs of athletes.

As an example of defects in footwear currently in circulation, many products, including general shoes and shoes for sports competitions, have a narrow toe and a narrow foot width due to an insole structure. This tendency is particularly strong in sports shoes because the foot and the shoe are required to be integrated. When the weight is applied to the narrow toes, the big toes and little toes become chronically stuck toes, and the joints of the big toes, which have nowhere to escape, become hallux valgus. Become. Accompanying these, various foot deformation disorders such as calluses and corns develop.

At existing footwear production sites, the insoles of footwear are designed from average data of human foot shapes. As a matter of course, it is extremely difficult to find a product that matches the foot shape of each individual user from existing footwear. Even with custom-made shoes, there is no product that measures the structure of the sole even if the foot shape is accurately measured. Various types of insoles are available on the market to cope with footwear that does not fit such feet. However, they are mainly insoles that act as cushions for adjusting the size of loose footwear, raising the area around the arch of the foot, and applying it to the painful part of the foot. Some shoe stores have installed machines that make custom-made insoles and sell expensive insoles that are made by accurately taking the mold of each individual foot, but this is the shape of the sole of the foot in the current state. Insoles are only laid, and there is no corrective effect on the affected foot. Users are dissatisfied with this current situation, but they have been complacent.

The number of people who suffer from deformity of the foot such as hallux valgus, bunion little toe, etc. is increasing, not only among women but also among men, along with the trend of designing narrow footwear. There is also a surge in young athletes, including children, in all sports such as soccer, track and field, table tennis, volleyball, and basketball. The number of patients in Japan alone exceeds 30 million.

The only current medical treatment for hallux valgus is osteotomy. It is a plastic surgery in which the thumb is amputated from the base of the thumb. In spite of the extremely painful operation, after the operation, the toes do not have strength, which interferes with daily life, and recurrence is also seen.

In existing footwear production sites, footwear is designed from average data of human foot shapes. Therefore, it is not easy to find footwear that fits the foot shape of each individual user from existing footwear. Also, there is currently no footwear that has a structure that corrects a diseased foot.

Projection of a total of 5 locations, 3 locations of thumb ball 9, 10 little toe ball, 11 heel and 2 locations of thumb 8 and little toe 7 in FIG. An insole 1 is laid on the insole of footwear, in which five portions 2, 3, 4, 5 and 6 are notched and each portion is dropped into the insole of the shoe. In addition, as shown in FIG. 3, there is also means for making five concave portions in the midsole of the footwear as a structural body when the footwear is manufactured. In addition, the notch examples in reference numerals 2 to 6 are examples of a healthy foot. A recess can also be formed by drilling.

As in the example of FIG. 1, if you put the insole with five cutouts 2 to 6 in your shoes, or wear the footwear of FIG. A medial longitudinal arch of the foot connecting the heel 11, a lateral longitudinal arch of the foot connecting the ball of the toe 10 and the heel 11, and a lateral arch connecting the ball of the big toe 9 and the ball of the toe 10 are formed. This shape is generally called a three-point arch. In addition to the three-point arch formation effect of the present invention, when the toe 8 is dropped into the insole by the notch 4 or the punch in FIG. While alleviating the pain of the bunion caused by the occurrence of the problem, the corrective effect of the user's own weight causes the bunion to varus and return to the original healthy foot shape, thereby healing or preventing the development of the bunion. Similarly, the notch 5 in FIG. While relieving pain, the corrective effect of the user's own weight restores the original healthy foot shape and prevents the onset of bunions or bunions. In addition to foot lesions, the grip of the sole on the insole of footwear is improved, reducing foot (leg) fatigue during standing work, and improving the comfort of wearing all types of footwear, from general footwear to sports shoes. improves.

Reference numeral 1 is the insole of the present application. Reference numerals 2 to 6 are diagrams showing the matching positions of the sole portion of reference numeral 12 and the insole, and reference numeral 2 is the heel. Reference numeral 3 is the thumb ball. Code 4 is the thumb. Reference numeral 5 is the little toe. Reference numeral 6 indicates the position of the ball of the toe. The parts 7 to 11 in the figure and the corresponding elliptical shape of the insole 1 are examples of notches or perforations of a normal foot shape. If you have hallux big toe or other foot deformity disorder, depending on the individual symptoms, the shape of 2 to 6 will be distorted and different in shape and position. . 1 is a perspective view of the insole of the present application mounted on a shoe; FIG. In addition, the notch portion of the insole of the present application is drilled into the inner sole of the shoe, and also serves as a diagram of an integrated structure.
