DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to a technical field related to shoes having a structure for assisting a function of grasping a toe during walking.

[0002]

2. Description of the Related Art Shoes having a material or structure capable of absorbing the flexion and load compression of a foot caused by walking and the impact from the ground have been on the market for a long time. Various types such as split type such as stepping part, insole type insole type, embedding type in heel heel part, air and other gas inside the hollow bag attached, and bag sealed type filled with gel-like substance Shoes with a simple structure are commercially available. Except where partial impact absorption and dispersion is required, the advantages that most of these structures and manufacturing methods can achieve are to absorb and disperse the impact from the sole of the foot when walking, and achieve comfort. And As in FIG. 1a, the human foot is not flat,
Due to the struggle of tree life several million years ago, as shown in FIG. 1b, the toes originally have a function of grasping an object, and this function enables a stable upright posture to be maintained.
In the shoe with the armor and the bottom, in the conventional shoe structure, the bottom is a two-layered structure of the insole and the outsole, or a three-layered structure of the insole and the outsole, the outsole is called the midsole on the lower surface Leather and cork,
There is a structure in which a foam such as synthetic rubber or sponge is mounted. And in such shoes, since the extremely soft material can not be used for the first half of the insole from the viewpoint of the durability of the shoe, it takes a considerable period of time until the inner bottom surface inside the shoe approaches the unevenness of the sole. In the meantime, in the period up to that time, the inside bottom surface of the shoe was almost flat, and as shown in FIG. In the case of the sole type, when the entire insole is made of the same material, the entire sole surface sinks, and the space between the insole surface and the sole surface is greatly reduced. This exerts pressure on the plantar flexor, which acts to grasp the toes, and is effective in absorbing shock from the ground, but it may interfere with the function of the skeleton and muscles inherent in the foot, and seeds near the base of the thumb In the case where the shock absorbing material is attached to a portion centered on the bone, the effect of dispersing the load in a portion where a large load is applied is effective, but the gripping function cannot be sufficiently expected even with this method. In addition, in a bag-sealed shoe with a hollow bag attached to the inner bottom or the lower surface of the inner bottom, any shape is possible depending on the shape of the bag, but in the hollow bag method, the inflated part is located at the bent part of the shoe In order to lead to a decrease in flexibility, near the metatarsophalangeal joint that is most bent, the bag is eliminated, or it is shaped like a narrow groove or small bag, rather than assisting the work of grasping things, Most shoes have a structure that focuses on shock absorption.

[0003]

With regard to the materials to be mounted inside shoes, materials for the purpose of absorbing shock from the ground by walking motion and means for mounting them have been greatly developed by improving the materials and the structure. Focusing on the skeleton and function of the foot of the person wearing the shoes, the function of the toes cannot be exhibited immediately from the time of purchase of the shoes. In addition, conventional shoes cannot contribute to the toe-grabbing action at the time of walking at all, and return poorly, so that they have a great feeling of fatigue at the time of walking and cannot withstand long-distance and long-time walking. Issues.

[0004] It is an object of the present invention to provide shoes that reasonably assist the grasping action of the toes originally possessed by human beings and have less fatigue when walking long distances and for a long time.
