Description

  The present invention is footwear such as shoes, sandals, clogs, sandals, slippers, etc., and can be walked as much as barefoot walking by adopting a configuration that does not restrict the movement of toes, and the size of the foot is selected. In addition, it is easy to insert each finger of the foot between the corresponding chords (hereinafter simply referred to as “wearing”), it is possible to easily obtain a rolling function of walking, and more naturally with the foot. It relates to footwear that can be.

It is said that more than 4 million years have passed since the monkeys began walking upright, and the ancestors of modern people, “Mitochondria Eve”, have been born 150,000 to 180,000 years ago. For most of the time, humanity has lived barefoot. This is because the ancient Egyptian sandals, which are said to be the oldest footwear, only appeared 4000 years ago.
In particular, the Japanese wore walaj after the barefoot era. A walad is a piece of soft straw placed on the sole of the foot and tied to the foot with a string called a cord, but it is made of a soft material and the bottom of the foot imitates the shape of the sole. Since it comes out at the bottom, it can be said that it is almost barefoot.
In this way, since history, until recently we have been walking barefoot or close to barefoot, and it should be said that our feet have a structure suitable for barefoot walking. Nowadays, many Japanese are wearing shoes, but only a few decades have passed since ordinary Japanese began to wear shoes. The shoes cover the five toes, the insteps and the ankles near the ankles, and the shoes are fixed to the feet while restraining the toes so that the shoes do not fall off the feet during walking. For this reason, there is a problem that it is impossible to walk normally unless shoes of a size suitable for the foot are selected.
Usually, people often choose shoes that match the length of the foot, but even if the foot length is the same, the width of the foot is wide but the thickness of the instep is high. For this reason, unless the foot length, foot circumference, foot height, arch height, heel width, etc. were measured and the shoes matched to each foot were custom-ordered, there was a problem that it was not possible to find a shoe that exactly fits your foot. .

The foot-rolling function in human walking is the function from landing on a heel to moving the weight forward and kicking with the thumb at the end, but the thumb is the second when kicking with the thumb at the end. Try to spread away from your finger.
Even if the size of the shoe is exactly the size of your foot, the shoe restricts the thumb from spreading inward, so it cannot be strung tightly with your thumb, and you can't force it with your third finger. There was a problem of hurting the knees and lower back by walking unreasonably without being able to protrude or even protruding. In particular, the longer the distance from the tip of the thumb to the toe of the shoe, the greater the problem that the protruding function is hindered.
In addition, the foot has a cushioning function called a vertical arch from the heel to the thumb and a horizontal arch from the thumb to the fifth finger. There was a problem that both the arch cushion function could not be exhibited and the knee and hip joints were damaged. In particular, pointed shoes, which are often used for women, tend to cause hallux valgus and the like, and have the problem of causing pain to women.
When a person walks, the movements of the feet and toes squeeze the vascular lymphatic vessels with the accompanying muscles, causing blood and lymph fluid to recirculate throughout the body (hereinafter simply referred to as “the milking action effect”). In order to limit the movement of the fingertips where the blood capillaries where blood is likely to stagnate when walking, there is a problem of inhibiting the action of milking action that can be originally obtained by walking.
On the other hand, footwear such as sandals, clogs, sandals and slippers has a problem of not being integrated with the foot. Sandals and clogs are better in condition than sandals and slippers because the umbilicus is sandwiched between the toes and the second finger, but there is still a relative displacement between the feet and the bottom. There was a problem that the clogs were lost. Hooked footwear such as sandals and slippers are worse than sandals and clogs in that they do not integrate with the feet and are not suitable for long walks.

Conventionally, there have been ideas and inventions in which the upper and the sole are connected with a umbilical cord (for example, see Patent Documents 1 to 3). Therefore, there is no function of guiding the tip of the toe when wearing, and the length of the umbilical cord itself is short, so that it lacks flexibility.
For this reason, there is a problem that the tip of the toe gets in the way of the snout, and it cannot be worn unless the tip of the toe is pushed between the snouts one by one using the hand, making it difficult to wear it. .
In addition, there were inventions and devices such as healthy footwear composed of two left and right upper ridges or belt portions and four finger side ridges (see, for example, Patent Documents 4 and 5). For example, there is no function of holding the foot flexibly by the above or a function of guiding the tip of the foot when putting on, and there is a problem that putting on becomes difficult as described above.
In addition, there have been devised and invented sandals in which a tubular portion into which five fingers are individually inserted and an instep belt are individually provided (see Patent Documents 6 and 7). There is no function to flexibly hold the foot or a function to guide the tip of the foot when putting on, and there is a problem that putting on becomes difficult as described above.
In addition, since the thongs of the inventions or devices of Patent Documents 1 to 5 do not have a function of grasping the toes, footwear slips during walking, and normal walking is difficult.
Furthermore, since the inventions or devices of Patent Documents 1 to 7 have separate thongs, there are problems that the number of parts is increased, the manufacturing process is increased, and the manufacturing cost is high.
Japanese Utility Model Publication No. 6-48403 Utility Model Registration No. 3033390 JP 2000-50901 A JP-A-9-37803 Utility Model Registration No. 3073758 Utility Model Registration No. 3082006 JP 2002-345501 A

The goal is to provide footwear that fits many people's feet.
In addition, when kicking with the thumb at the end of the rolling function, it is possible to exert a cushion function of the vertical arch and the horizontal arch without restricting the movement of the thumb away from the second finger and spreading inward, The problem is to eliminate the problem of hurting the knees and lower back of conventional shoes, and in particular to free women from pain caused by hallux valgus.
In addition, as a footwear that does not restrict the movement of the fingertips where blood capillaries that are prone to blood stagnation can be obtained, the action of milking action by walking and the effect of improving blood circulation by stimulating the base of the finger can be obtained. To provide footwear.
Also, to eliminate footwear, sandals, sandals, slippers and other problems that do not become integral with the foot, and to provide footwear suitable for walking for a long time that does not fall off even when walking fast is there.
In addition, the invention of connecting the instep and the sole with a umbilical cord, the invention of a healthy footwear composed of two left and right upper ligaments or a belt portion and four finger lanyards, etc. There is no function to hold the foot flexibly with footwear or the function to guide the tip of the toe when wearing, such as the idea of a sandal with a tubular part that individually inserts the finger and an instep belt It is to provide footwear that eliminates the problem of difficulty in wearing.
In addition, it is a footwear that is integrated with the instep and has a function of grasping the toes and that allows normal walking without slipping during walking, and further simplifies the manufacturing process and reduces manufacturing costs. The object is to provide footwear that can be reduced.

The present invention is a footwear having a bottom and an upper made of a soft material. Then, five openings are provided in the toe of the upper, and when the tip of the foot is inserted into the upper, the upper becomes a guide and the five fingertips are guided to the corresponding openings. The footwear that facilitates individually protruding the five toes from the opening.
Then, a wide portion between the openings is used as a nose portion, and the wide nose portion is folded between the toes so that the toes are grasped by the nose portion.

Since the present invention releases the entire area around the toes and forms a cover made of a soft material, even if the cover is large relative to the foot, the foot and the footwear are easy to walk, and many people's feet. We were able to provide footwear that fits perfectly.
In addition, the present invention does not restrict the movement of the thumb trying to spread inward when kicking with the thumb at the end of the rolling function, and it is possible to demonstrate the cushion function of the vertical arch and horizontal arch, so that the knee and waist I was able to eliminate the problem of hurting.
In particular, according to the present invention, since all of the toes are released and the footwear does not cause a hallux valgus, women can be freed from pain caused by hallux valgus and the like.
In addition, according to the present invention, as footwear that does not restrict the movement of fingertips where blood capillaries that are prone to stagnation of blood, the effect of milking action by walking and the effect of stimulating the base of the finger to further improve blood circulation We were able to provide footwear that can be obtained.
