[0023] The specific embodiment is a kind of degradable high elasticity foamed insole, its structure schematic view as shown in Figures 1-4 Including foamed base layer 1, foamed base layer 1 inside is equipped with airflow channel 2, airflow channel 2 top surface is fixedly connected with a plurality of first support column 3, airflow channel 2 bottom surface is fixedly connected with a plurality of second support column 4, first support column 3 and second support column 4 are staggered distribution, foamed base layer 1 upper and lower surfaces are equipped with air hole 5 respectively, air hole 5 all are communicated with airflow channel 2.

[0024] When the foamed base layer 1 is stressed, the airflow channel 2 is compressed downward, and the airflow in the airflow channel 2 is discharged through the air holes 5. When the airflow is discharged into the shoe, the airflow in the shoe is also blown out, and the external airflow enters the shoe, which is circulated to improve the ventilation effect of the shoe and the insole. At the same time, the first support column 3 of the foamed base layer 1 moves downward when the foamed base layer 1 is stressed to a certain extent. The first support column 3 contacts the bottom of the airflow channel 2, and the second support column 4 contacts the top of the airflow channel 2, which supports and buffers the foamed base layer 1 as a whole, avoids the foamed base layer 1 from being stressed repeatedly, and avoids problems such as collapse, deformation, or cracking. By arranging the first support column 3 and the second support column 4, the strength of the insole can be increased without affecting the ventilation effect.

[0025] As shown in Figure 2 and Figure 3 , the foamed base layer 1 is connected with a breathable fabric 6 on the upper surface, and a plurality of circular holes 7 corresponding to the air holes 5 are arranged on the surface of the breathable fabric 6. The upper surface of the breathable fabric 6 is fixedly connected with a plurality of first anti-skid pieces 9. The upper surface of the foamed base layer 1 is coated with adhesive 8, and the breathable fabric 6 is connected with the foamed base layer 1 through the adhesive 8.

[0026] Specifically, the breathable fabric 6 is made of cotton, canvas, non-woven fabric, polyester fiber, or other materials, and is bonded by the adhesive 8. On the one hand, the breathable fabric 6 can absorb sweat from the user's feet, further improving the user's comfort, and on the other hand, the breathable fabric 6 can protect the foamed base layer 1 from being eroded by sweat for a long time, thereby prolonging the service life of the foamed base layer 1. In addition, the first anti-skid pieces 9 can increase the friction between the insole and the user's feet, especially when the user is wearing socks and running or exercising, to prevent the socks from slipping on the insole.

[0027] As shown in Figure 3 , the lower surface of the foamed base layer 1 is fixedly connected with a plurality of second anti-skid pieces 10. The second anti-skid pieces 10 can increase the friction between the foamed base layer 1 and the bottom of the shoe. After the insole is placed in the shoe, the insole can always remain in the same position during walking or intense exercise, further increasing the stability of the insole.

[0028] As shown in Figure 1 and Figure 2 , the air holes 5 are distributed in a circle along the edge of the foamed base layer 1. By this design, the ventilation effect of the foot can be improved. Even if the air holes 5 are distributed on the underside of the foot, when the foot is forced downward, most of the air holes 5 will be blocked, and the ventilation effect will not be good. However, the air holes 5 are arranged near the edge of the foamed base layer 1, which can also improve the uniformity of the ventilation inside the shoe.

[0029] As shown in Figures 1-3As shown, the wear-resistant layer 11 is fixedly connected to the side edge of the foamed base layer 1.

[0030] As shown, Figure 3 As shown, the first support column 3 and the second support column 4 are both half the height of the airflow channel 2.

[0031] When the foamed base layer 1 is deformed downward under stress, the foamed base layer 1 can avoid excessive bending and material fatigue, effectively prolonging the service life of the insole.

[0032] In addition, the shoelace in the present scheme is prepared from degradable materials, and the degradable materials can be any one of starch-based biodegradable materials, polylactic acid, polyhydroxyalkanoate, plant fiber foaming materials and the like.

[0033] All the technical features in the present embodiment can be freely combined according to actual needs.

[0034] The above embodiment is a preferred implementation scheme of the present application, and in addition to this, the present application can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
