[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a full laying of shoes and a leather lining, and in particular, it is effectively used in, for example, women's shoes, and has deformed feet such as open feet (fan-like feet), flat feet, and hallux valgus. The present invention relates to a full laying of shoes and a laying leather which is effective in preventing the occurrence of heat and is effective for keeping a healthy foot.

[0002]

2. Description of the Related Art For example, women's shoes such as high heel pumps are always required to be fashionable and elegant, so that the toes tend to be tighter.

[0003]

However, in such women's shoes, various obstacles are often caused due to a concentrated load of weight due to a mismatch with the shape of the wearer's foot. That is, if such a tight women's shoe is worn and standing work is continued for a long time, the metatarsal head from the second to the fourth part of the foot falls, and the lateral metatarsal ligament gradually loosens or extends. . As a result, the arch of the foot bone in the cross-sectional direction (horizontal arch) and the arch of the foot bone in the longitudinal cross-section (vertical arch) are collapsed, and the sensation of pushing up from below is generated. Legs such as feet) and flat feet will be deformed, and it will become impossible to maintain a healthy foot. In addition, when the lateral arch collapses to form an open leg, the first metatarsal bone head opens inward, that is, the base of the big toe pops out, causing valgus.

On the other hand, such a wide women's shoe that conforms to the shape of the foot, that is, so-called
Women's comfort shoes are on the market,
Naturally, such women's comfort shoes sacrifice fashionability and elegance.

Therefore, the present invention has been made in view of the above, and, for example, in a women's shoe or the like which emphasizes fashionability and elegance, a failure due to a concentrated load of weight due to a shape mismatch is caused. It is an object of the present invention to provide a full-length shoe and leather coverings that can prevent such a situation.

For this reason, the invention according to claim 1 has a planar shape that substantially matches the shape of the sole, and has a sole shape from the vicinity of the metatarsal head contact portion of the foot to the heel portion. A full lay of a shoe curved along the first ridge, the second ridge, and the third ridge, wherein the arch portion is near the metatarsal head contact portion of the foot. Curved along the sole shape from the to the heel portion, the first raised portion is raised from a portion corresponding to the vicinity of the soil contact of the foot on the sole contact surface side, the second raised portion, The foot is abutted on the sole contacting surface side from a portion corresponding to the vicinity of the metatarsal bone abutting portion so as to substantially follow the curved shape of the metatarsal bone, and the third raised portion is a foot on the ground contact surface side. The second to the fourth metatarsal heads are raised from the portion in contact with them.

According to a second aspect of the present invention, the thickness of the portion including the second raised portion is about 4.0 to about 8.0 mm, and the third portion is
The thickness of the portion including the ridges is about 4.0 to about 8.0 mm,
The thickness of the heel portion was about 2.0 to about 5.0 mm.

The invention according to claim 3 is the invention according to claim 1 or 2.
The whole sheet described was formed into a sponge.

According to a fourth aspect of the present invention, there is provided a full laying of the shoe according to any one of the first to third aspects, and a hole which is provided on the back surface of the full laying and into which the third raised portion is fitted. An insole for shoes configured by combining with an insole.

[0010]

[Function] When the load of the body is concentrated due to the incompatibility between the shoe and the foot shape of the wearer, the lateral metatarsal ligament gradually loosens or extends, and as a result, first, the cross-sectional direction of the foot bone. The arch (horizontal arch) collapses and becomes an open foot (fan-shaped foot).

Further, when the arch of the bone of the foot in the direction of the longitudinal section (vertical arch) collapses, the foot becomes flat.

Further, when the arch of the bone of the foot collapses as described above, the first metatarsal bone head opens inward and valgus hallux occurs due to the collapse of the lateral arch.

According to the first aspect of the present invention, the vertical arch is mainly collapsed by providing the soil faulty pad portion protruding from the portion corresponding to the soil faultlessness of the foot on the sole contact surface side. By providing a metatarsal pad part that can be prevented and rises so as to substantially follow the curved shape of the metatarsal bone from the site near the metatarsal bone abutting part on the sole contact surface side, It is possible to prevent collapse of both the arch and the side arch. In addition, by providing the metatarsal head pad portion that bulges from the site where the second to fourth metatarsal heads of the foot on the ground contact surface contact,
The metatarsal head pad part serves as an appropriate cushioning layer, and mainly the collapse of the lateral arch can be prevented.

According to the second aspect of the invention, the thickness of the portion including the second raised portion, the thickness of the portion including the third raised portion, and the thickness of the heel portion are set to specific dimensions. The above effect can be more effectively achieved.

According to the third aspect of the present invention, since the whole floor is formed in a sponge shape, it is slightly pressed by the weight of the wearer to increase the substantial size of the foot in the shoe. .

According to the invention of claim 4, in the case of the leather laid with the whole sole and the insole combined, the metatarsal head pad part is fitted and fixed in the hole of the insole. Since the position of the metatarsal head pad part does not shift from the position of the metatarsal head part of the foot when worn, the circumference of the metatarsal head pad part is supported by the insole. It reliably abuts on the metatarsal head and pushes up the metatarsal head securely so as not to go down, and a sufficient cushioning effect is obtained.
