[0020] Airflow channel includes main channel 30 adapted with first gas joint 21, and the one end of main channel 30 away from first accommodating recess 2 is shaped with several branch channels 31;Each branch channel 31 is the fan-shaped structure with both ends communicated with main channel 30, and each branch channel 31 is distributed in the form of annual ring at the forefoot of insole body 1.

[0021] In use, branch channel 31 is the fan-shaped structure with both ends communicated with main channel 30, and each branch channel 31 is distributed in the form of annual ring at the forefoot of insole body 1, and the gas of each branch channel 31 is converged to main channel 30 when air bag 20 inhales, to ensure effective absorption of the gas in the inside of shoe.

[0022] The air bag 20 is internally provided with a spring member 23, and the first gas joint 21 and the second gas joint 22 are both one-way conduction structures.

[0023] In use, the spring member 23 is fixedly connected to the top and bottom inner surfaces of the air bag 20, and the spring member 23 provides a stable reset force for the air bag 20 to quickly reset after each time being stepped on.

[0024] The first gas joint 21 allows the gas in the main channel 30 to enter the air bag, and the second gas joint 22 allows the gas in the air bag 20 to be discharged out of the insole. Both the first gas joint 21 and the second gas joint 22 are one-way conduction structures, and the specific one-way conduction structure is consistent with the structure and working principle of the prior art “one-way valve”, which will not be described here.

[0025] The insole body 1 is provided with a pad 4 on the top surface, and the pad 4 separates the accommodating recess 2 and the airflow channel 3 into separate cavities. The pad 4 is formed with a recessed protrusion 40 at the heel, which is adapted to the air bag 20. The pad 4 is formed with a recessed rib 41 at the corresponding position of each branch channel 31, and the recessed rib 41 is distributed with a plurality of air holes 42.

[0026] In use, the pad 4 is fixedly connected to the insole body 1 (stitched or glued) to close the opening of the accommodating recess 2 and the airflow channel.

[0028] In use, when the air bag 20 inhales, each branch channel 31 absorbs the gas inside the shoe through the densely distributed air holes 42 and converges to the main channel 30. When the diameters of the air holes 42 are consistent, the air holes 42 closer to the main channel 30 will absorb more gas, which means that the air holes 42 far from the main channel 30 will absorb less gas, resulting in uneven absorption of air inside the shoe by each air hole 42. This means that the absorption force and amount of gas by air holes 42 of different diameters are not uniform, resulting in uneven air circulation inside the shoe and affecting air exchange quality. The diameter of the air hole 42 gradually decreases from the head to the heel of the pad 4. When inhaling, part of the gas is quickly and in small amounts discharged through the small-diameter through hole, and another part of the gas is slowly but in large amounts discharged through the large-diameter through hole, ensuring that the gas absorption amount of each air hole 42 is more uniform, and ensuring efficient discharge and circulation of air inside the shoe.
