Description

The present invention relates to footwear, and more particularly to footwear that contributes to the reduction of national medical-related costs by actively bending and stretching human toes to promote health and prevent aging. ..

Traditionally, the back of a person's foot, especially the toe joint, is an important part that is said to be the second heart of a human being, and repeated up and down movements of the toes promote blood circulation. In addition, the effective return of blood from the blood vessels at the ends of humans to the heart greatly contributes to human metabolism, and this has attracted a great deal of attention regarding health maintenance, and in recent years, this point has been particularly noticeable. It has been regarded as important, and it has begun to be used for the prevention and treatment of hallux valgus, floating fingers, and flat feet. It is also expected to be used for the prevention of cold feet, the prevention of falls in the elderly, and the improvement of walking disorders. Has been done.

In recent years, the toe gooper exercise, which has become a hot topic in the world, has been attracting attention as an exercise that anyone can easily perform based on such knowledge.
That is, in recent years, there has been increasing recognition that activating the movement of the back of the human foot, especially the toes, is important for the treatment and prevention of the above-mentioned various disorders and diseases.

By the way, what is called athletic shoes as footwear that has been generally used in the past, when wearing this, walking or running, only the fingertip direction of the athletic shoes is the horizontal plane of the front part. On the other hand, the current situation is that it only has a function of swinging upward, and as described above, it does not have a function of actively and greatly swinging the toes.
That is, in many conventionally used athletic shoes, when walking, running and running, the toe portion is in a warped state toward the upper side, but in the lower direction. There was a problem that it did not become bent.

On the other hand, conventionally, in the field of footwear, there have been some attempts to bend the toe portion downward from the bottom surface of the footwear. 2017-121388 (Patent Document 1) is known, but in the known example, a specific example as footwear is a footwear, and in the footwear, a footwear plate portion corresponding to a toe portion. Is deleted so that the remaining toes, including the toes, can be bent downward from the plane of the footwear plate, but in the known example, each toe can be easily bent downward. Even if it is possible, there is no configuration in which each toe is positively inverted and raised from its lower position upward, so the vertical movement of the toe should be effectively carried out. Is impossible.

Further, Japanese Patent No. 3369858 (Patent Document 2) is known, but in the known example, the shoe is intended to firmly fix the toes inside the shoe and maximize the treading force. The surface of the insole is provided with a convex portion at the base of the toe that is inserted into the gap between the toes, and a concave portion on the posterior end side where the metatarsophalangeal portion can be aligned and a toe tip portion at the anterior end portion thereof. Disclosed is a structure of a shoe in which the recess is provided so that the recess of the toe tip portion is lower than the surface of the insole portion of the shoe.

However, in the known example, the toe tip is provided only with the toe tip matching recess for the purpose of fixing the position of the toe at the time of treading to the extent that it does not shift in the horizontal direction. It is clear that it is not intended to bend the part deeply, strongly and positively.
However, in the known example, there is no disclosure or suggestion regarding the inversion of the toe tip from the downwardly bent state and turning it upward at a large angle, that is, upward of the shoe. it is obvious.
Further, as prior art related to the present invention, International Publication No. 2011-059045 (Patent Document 3), Jikkenhei 3-079704 (Patent Document 4), Japanese Patent Application Laid-Open No. 2007-061563 (Patent Document 5), and registration of a practical new proposal. Japanese Patent Application Laid-Open No. 3024538 (Patent Document 6), Japanese Patent Application Laid-Open No. 2006-051305 (Patent Document 7), Japanese Patent Application Laid-Open No. 3154424 (Patent Document 8), etc. are known, but in the prior art. However, although a shoe in which a recessed recess is formed in a portion of the bottom of the shoe where the tip of the toe abuts is disclosed, in any known example, the tip of the toe is the recess. Inside the dented part, it is always placed in a state where it is swaying freely and without any restrictions, and when the stepping motion is performed, the tip of the toe is caught in the stepped part of the reciprocating part. Only the action of bending inward is performed, and such a motion is only a completely opposite motion different from the flexion motion of the toe tip in the present invention, and further, a characteristic motion in the present invention. It must be said that there is no chance that the function / movement of the toe tip flipping outward will occur at all.
That is, the third to eighth patent documents are merely prior arts completely unrelated to the present invention.
Therefore, in recent years, there has been a long demand for shoes having the above-mentioned functions and capable of greatly moving the toes while wearing the shoes.
