FIELD OF THE INVENTION This invention relates to breathable shoes.

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. 33-13450, an exhaust groove is continuously provided to a pump chamber formed in a heel portion via an exhaust check valve, and an exhaust check valve is provided. A ventilated shoe with an insole having an intake groove inserted into the shoe, or a midsole made of a soft foam having an air chamber that communicates with the underside of the insole according to Japanese Utility Model Publication No. 38-1306. A ventilated shoe has been proposed that has a shoe sole with multiple layers. However, the former has a drawback that the structure is complicated and the check valve is damaged by landing impact or bending action that is repeatedly applied during use, or falls off from the mounting part, and lacks durability, while the latter has a drawback of walking or Due to the movement of the body weight pressure applied to the shoe during the running process, the midsole is excessively compressed and deformed at the inner side portion or the outer side portion thereof, causing the foot to sway in and out, resulting in poor walking or running stability. There was a flaw.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to eliminate these drawbacks and to provide a breathable shoe having excellent durability, walking and running stability.

[0004]

The present invention will be described below with reference to the accompanying drawings. In the present invention, a soft elastic shoe sole 1 having holes 11.11 ...
Corresponding to 1.11 ..., the plate 2 integrally formed with bellows-shaped projections 21.21 ... which are higher than the depth of the holes 11.11 ... .11 ...
A breathable shoe characterized in that the breathable insole 3 is placed on the plate 2 and the breathable insole 3 is overlaid on the plate 2 to form a gist of the invention.

In the present invention, the soft elastic shoe sole 1 is composed of a usual shoe sole molding material such as rubber, vinyl chloride resin, EVA, polyurethane or the like. The shoe sole may be a solid body or a foam body, or the outer sole may be a solid body and the middle sole may be a foam body. The shoe sole 1 is provided with an appropriate number of holes 11.11 ... Opened on the upper surface thereof at a location where the weight pressure load is large when the user wears the heel portion, the tread portion, and the like. These holes 11.11 ...
It would be convenient if was molded at the same time when the shoe sole 1 was molded.

In the present invention, the plate 2 is made of a semi-rigid or hard resin such as a hard vinyl chloride resin, polyethylene, polypropylene, polyamide, or Avis resin, and is formed in correspondence with the entire shape of the shoe sole or the front sole or the heel sole. Has been done. The bellows-shaped projections 21.21 ... Are integrally formed with the plate 2 so as to correspond to the holes 11.11. The bellows-shaped projections 21.21 can be integrally formed with the plate 2 by vacuum molding using the plate-like thermoplastic synthetic resin.

In the present invention, the insole 3 is provided with ventilation holes 31.31 ... if necessary, or is made of open-cell foam, nonwoven fabric or the like having air permeability itself. In the case of providing 31.31 ..., the ventilation holes 31.31 ... are set so as to be located on the upper surface of the opening of the bellows-like projections 21.21. In the present invention, if necessary, between the plate 2 and the shoe sole 1,
If an elastic foam 4 softer than the shoe sole 1 is interposed,
Due to the compressibility and impact resilience, the air permeability can be further improved.

[0008]

Since the present invention is constituted as described above, when walking or running while wearing the shoe according to the present invention, the heel portion is first landed in the walking or running process, and the sole of the shoe is caused by body weight pressure. The heel portion of No. 1 is compressed, the holes 11.11 ... Are compressed at the heel portion, and the holes 11.1
The bellows-shaped projections 21.21 ... Inserted in 1 ... are compressed, and the air interposed in the projections 21.21 ... is forcibly discharged into the shoe through the breathable insole 3. Next, the landing of the heel portion is completed, the body weight pressure is moved to the tread portion, the tread portion of the shoe sole 1 is compressed, and the compression of the heel portion is released. As a result, the holes 11.11 ... Are compressed in the stepped portion, and the bellows-shaped projections 2 inserted into the holes 11.11.
The compressed air in the projections 1.21 ... and the air interposed in the projections 21.21 is forcedly discharged into the shoe through the breathable insole 3, and the compressed air in the heel portion 11.11.
However, due to the resilience of the sole and the resilience of the bellows inserted into the hole 11.11, the bellows-like protrusion 21.21.
Is restored to its original shape, and the air in the shoe is forcibly sucked into the bellows-like projections 21.21 ... through the breathable insole 3.
Therefore, a flow of air is forcedly produced from the stepped part to the heel part in the shoe. In the next continuous walking and running process,
The heel portion of the shoe 1 is continuously compressed, and at the same time, the compression of the stepped portion is released, and conversely to the above, the air flow is forcibly caused from the heel portion to the stepped portion of the shoe. Therefore walking
During the running process, air is forcibly circulated from the toe part to the heel part and from the heel part to the toe part in the shoe, the air permeability in the shoe is good, and the unevenness in the shoe is prevented. On the upper surface of the sole 1,
Since the base portion 10 of the toe is located, the outer side portion or the inner side portion of the shoe sole 1 is not excessively compressed during the walking or running process, and the foot does not laterally shake during walking or running. It is possible to provide shoes having excellent running stability.
