For example, from the aspect of the material of each component that composes shoes, from upper material, material of outsole and midsole, shoelace, eyelet to sewing thread and adhesive,
Much research and development has been done on the weight reduction of the material itself.

[0003] On the other hand, various researches and developments have been conducted also from the aspect of shoe structure. For example, U.S. Pat. 4107
No. 857 discloses a shoe having a structure in which a strap corresponding to the inner instep and the outer instep of the shoe sole is provided instead of a part of the upper material for the purpose of weight reduction, and the tip of the strap is eliminated. Have been. Also, Japanese Patent Application Laid-Open No. 8-317806 discloses a technique for reducing the weight of the entire shoe using an upper and a belt.

[0004]

However, research on weight reduction of materials has reached a certain limit, and today it is difficult to reduce weight of materials to exert an effective effect on weight reduction of shoes as a whole. I have. Further, in each of the above-described inventions and the like, a predetermined amount of the upper material is required, so that there is a limit in reducing the weight of the entire shoe. Further US patent
NO. In the shoe described in Japanese Patent No. 4107857, a corresponding strap on the inner and outer insteps had to be tied, which was inconvenient and not practical. In view of the above, the present invention makes it possible to solve the problem of further weight reduction by configuring the shoe without using any upper material, especially for athletics shoes for which there is a high demand for weight reduction.

[0005]

To solve the above problems, an athletics shoe according to the present invention comprises a sole, a plurality of enclosures, a toe protector, a heel protector, and a side reinforcement. And a fastener. That is, one end of the enclosure is fixed to the peripheral edge of the sole, and the other end has a fastener locking structure. The toe protecting material is formed for the purpose of protecting the toe of the wearer from the road surface, but the toe of the toe of the wearer is so formed that the toes do not protrude from between the enclosures. It is also possible to have a shape that covers the entire part in front of the ball or ball.

The side reinforcing member is fixed to each of the surroundings above the heel protection member and in the vicinity of the fastener locking structure, and a fastener such as a shoelace or a belt is locked to the fastener locking structure. By forming in this manner, the fastening device locking structure can be integrated into the instep portion, and it is easy to use when locking shoelaces and the like, and the direction in which the surrounding body is pulled can be regulated. Optimum fit can be obtained when tightened with a fastener.

The material and the shape of the enclosure are not particularly limited, but the material is preferably made of a highly elastic synthetic resin fiber or the like having a small elongation, and the shape is a tape having an appropriate width. It is preferable to form it.

Although the sole according to the present invention can have various configurations according to the type of the used item, the sole formed from a relatively resilient and lightweight synthetic resin from the toe portion to the heel portion. A heel wedge made of a material rich in cushioning properties can be laminated and integrated on the upper surface of the heel portion of the plate. Furthermore, in shoes for short-distance events in which the sole is formed of a hard resin, the sole is formed only in the forefoot from the toe to the vicinity of the arch, and in the vicinity of the heel, conventionally used. It is also possible to use a sheet-like impact absorbing member or an anti-slip material such as a sharkskin.

[0009] In some sports, to improve the contact of the shoelace or the like with the feet, the fastener fastening structure and a tongue piece covering the lower surface of the fastener may be attached to an appropriate portion such as the toe protecting material. It is possible.
