  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described below with reference to the drawings.

[Configuration of insole with anti-steaming function]
The insole with an anti-steaming function of the present embodiment (hereinafter referred to as an insole) is an elliptical cross-section tube to solve the problem caused by the meandering of the tube 2a of the conventional insole, that is, the problem of misalignment between the small hole 4 and the air hole 5. 12a is adopted. FIG. 1 is a diagram illustrating a configuration of an insole with a dampness preventing function according to the present embodiment. The basic configuration is the same as that of the conventional insole 10. That is, the upper layer portion 11, the middle layer portion 12, and the lower layer portion 13 are configured by sewing with the sewing thread 6 and finishing. In FIG. 1, the upper layer part 11 is a leather material, and the lower layer part 13 uses a mesh material. By employing the mesh material for the lower layer portion 13, drying of the sweat on the sole can be promoted. Further, by adopting a leather material for the upper layer portion 11, for example, when the insole 20 is used for leather shoes, it is possible to maintain a high-class feeling of the shoes.

  The middle layer portion 12 is configured by a plurality of elliptical cross-section tubes 12a having an elliptical cross section. By adopting the tube having this cross-sectional shape, meandering during use can be prevented. This will be described in detail later. The upper layer 11 has a plurality of small holes 4 and the elliptical cross-section tube 12 a has a plurality of air holes 5 as in the conventional insole 10.

  FIG. 2 shows an insole 21 in which the upper layer portion 14 is made of a sponge material and the lower layer portion 15 is made of a finer mesh material than the lower layer portion 13 of FIG. This insole 21 is used, for example, for athletic shoes worn by track and field runners. By using the upper layer portion 14 as a sponge material, it is possible to absorb the impact of the foot. In addition, the point by which the middle layer part 12 is comprised by the elliptical cross-section tube 12a is the same as that of the insole 20 of FIG.

  FIG. 3A shows a case where only the peripheral tube of the insole is configured by an elliptical cross-section tube 12b having a large diameter. Thus, by increasing the diameter of the tube at the peripheral edge of the insole, the side of the foot can be stimulated from the back of the heel, and the insole can be made more comfortable. FIG. 3B shows an example in which trapezoidal cross-section tubes 16a and 16b having a trapezoidal cross section are employed for the tube. Thus, by adopting a trapezoidal cross section with a flat bottom surface, the meandering of the tube can be further prevented. In FIG. 3B, the middle layer portion may be constituted only by the trapezoidal cross-section tube 16a having a small cross-sectional area.

[Use condition of insole with anti-steaming function]
FIG. 4A shows the use state of the insole 20 using only the elliptical cross-section tube 12a, and FIG. 4B shows the use state of the insole using the elliptical cross-section tube 12a and the elliptical cross-section tube 12b having a large cross-sectional area. Show. As can be seen from FIGS. 4 (a) and 4 (b), the tube can be stably restrained between the upper layer portion and the lower layer portion by making the cross section of the tube elliptical, thereby preventing meandering of the tube. Thus, the positional deviation between the small holes 4 and the air holes 5 is eliminated, and the stuffiness preventing function is sufficiently exhibited. Moreover, as shown in FIG.4 (b), it can be set as a very comfortable insole by comprising the peripheral part of an insole with the elliptical cross-section tube 12b with a large cross-sectional area.

  FIG. 5A shows the use state of the insole using only the trapezoidal cross-section tube 16a, and FIG. 5B shows the use state of the insole using the trapezoidal cross-section tube 16a and the trapezoidal cross-section tube 16b having a large cross-sectional area. ing. As can be seen from FIGS. 5 (a) and 5 (b), by making the cross section of the tube trapezoidal, the tube can be more stably restrained between the upper layer portion and the lower layer portion. This prevents the misalignment between the small hole 4 and the air hole 5. Moreover, as shown in FIG.5 (b), it can be set as a very comfortable insole by comprising the peripheral part of an insole with the trapezoidal cross-section tube 16b with a large cross-sectional area.

[Air flow in the insole with anti-steaming function]
The action of the insole 20 during walking will be described with reference to the cross-sectional view of FIG. When walking, as shown in FIG. 6A, when the heel lands and the weight moves from the heel on the sole toward the fingertip, the air movement in the hollow tube 12a moves from the heel side toward the fingertip. Compressed. The compressed air mass shown in FIG. 6 (b) moves toward the tip of the tube 12a, and the air hole 5 drilled in the tip of the tube 12a by the action of kicking the ground with the fingertip shown in FIG. 6 (c). Compressed air is discharged from the finger holes through the small holes 4 in the upper layer portion 11 of the insole 20.

  The compressed air released from the air holes 5 generates a flow of air around the finger, lowers the humidity due to sweating between the fingers and prevents stuffiness, and suppresses the generation of odors caused by germs. . In addition, by forming the lower layer portion 13 of the insole 20 with a mesh cloth, moisture of the sole 20 absorbed by the epidermis forming the upper layer portion 11 is diffused to prevent the insole 20 from getting wet, Demonstrates the effect of preventing dampness.

  Furthermore, the entire sole of the tube 12a has a corrugated shape of the tube 12 and a compressed air mass in the tube 12a is moved by walking, thereby exerting an acupressure effect that stimulates the entire sole and reducing and recovering fatigue. .

  As described above, according to the present embodiment, it is possible to provide an insole with a dampening function that sufficiently exhibits a dampening function even when used for a long period of time.

[Slippers with anti-steaming function]
The present embodiment is an example in which the insole 20 described in the first embodiment is used as the slipper 40. FIG. 7 is a diagram showing the appearance of this slipper. In this slipper, the insole 20 is not used as an insole but is used as a slipper bottom. If you wear these slippers, you can feel the sense of walking on the lawn.

  According to the present embodiment, it is possible to provide a slipper that stimulates the sole and is comfortable to wear, and can prevent the foot from becoming stuffy.

[Shoes using insoles with anti-steaming function]
FIG. 8 is a diagram illustrating an appearance and an internal structure of a shoe using the insole described in the first embodiment. As shown in FIG. 8A, the shoe of this embodiment has a front air hole 30a on the front side of the shoe and a rear air hole 30b on the rear side of the shoe. Of course, it goes without saying that the insole of the present invention can be used for shoes that do not have these air holes.

  As shown in FIG. 8B, the outside air that has entered from the rear air hole 30b passes through the small hole 4 and the air hole 5 and then passes through the tube 12a. Thereafter, the air passes through the front air hole 5 and the small hole 4 and is discharged to the outside from the front air hole 30a. In this way, by allowing the outside air to actively pass through the inside of the shoe, it is possible to further exhibit the function of preventing the insole from becoming damp.

  According to this embodiment, it is possible to provide a shoe using an insole with an anti-steaming function capable of stimulating the sole and being comfortable to wear and preventing the foot from stuffy.
