As shown in figure 1, the vamp with air bags has the overall structure that the vamp 1, the air bags 2, the air pipe channels 3 and the air pipes 4 are arranged. The vamp 1 can be a common vamp which is woven by warp knitting, tatting and other processes. The air bag 2 is fixed on the vamp 1 in a high-temperature electric heating mode. Specifically, in this embodiment, the material of the airbag 2 is TPU. The air pipe channel 3 and the air bag 2 are integrally manufactured and are fixed on the vamp 1 in a high-temperature electric heating mode. The trachea channel 3 is hollow and has a channel between it and the shoe upper 1 for the trachea 4 to pass through. The air pipe 4 is a hollow flexible pipe capable of ventilating, the size and the diameter of the pipe are matched with those of the air pipe channel 3, one end of the air pipe passes through the air pipe channel 3 and is communicated with the inside of the air bag 2, and the other end of the air pipe is connected with an air charging and discharging device (not shown). The air charging and discharging device can be manual or electric, and the electric air charging and discharging device generally comprises an air pump, a power supply, an electromagnetic valve, a control switch and the like.

As shown in fig. 2, the vamp 1 is provided with a through opening 11, and the area of the through opening 11 is smaller than the cross section area of the air bag 2, so that the peripheral area of the air bag 2 can be fixed on the vamp 1 in a high-temperature electric heating mode. Specifically, in this embodiment, the balloon 2 includes an upper TPU film 21 and a lower TPU film 22, and the airway passage 3 is integrally formed with the upper TPU film 21.
