4442 of the second regulating lever 444, the air pipe 4433, the air nozzle 413 and the first air bag 41. Thus, when the second air bag 42 is stepped by the foot heel 51, the second air bag 42 is contracted to compress the compression elastomer 422, and the air in the second air bag 42 in turn passes through the second inlet pipe 425, the second oneway air inlet 441 of the second control valve 44, one of the two second connecting pipes 4431 and 4431a of the second io oneway valve seat 443, the second connecting channel 4442 of the second regulating lever 444, the air pipe 4433 and the air nozzle 413 into the first air bag 41 so as to inflate the first air bag 41. On the contrary, when the second air bag 42 is released from the foot heel 51, the second air bag 42 is expanded by the restoring force of the compression elastomer 422 to produce a suction force, and the air from the ambient environment is drawn inward and in turn passes through the first connecting channel 4342 of the first regulating lever 434, one of the two first connecting pipes 4331 and 4331a, the first oneway air inlet 431 and the first inlet pipe 424 into the second air bag 42 as shown in FIG. 8. In such a manner, the second air bag 42 is contracted and expanded reciprocally by actions of the foot heel 51, so that the first air bag 41 is inflated successively and is stretched in the wearing space 11 of the vamp 10 to encompass a foot 50.

Referring to FIGS. 9 and 10 with reference to FIGS. 2-6, when the first control switch 4345 of the first regulating lever 434 and the second control switch 4445 of the second regulating lever 444 are rotated to align with the

Hold indication character of the sole 20 as shown in FIG. 9, the first connecting hole 4343 of the first regulating lever 434 is isolated and sealed by the wall of the first mounting tube 4332 of the first oneway valve seat 433 to close the first oneway air inlet 431 of the first control valve 43, and the two second connecting holes 4443 and 4443a of the second regulating lever 444 are isolated and sealed by the wall of the second mounting tube 4432 of the second oneway valve seat 443 to close the second oneway air inlet 441 of the second control valve 44.

Referring to FIGS. 11 and 12 with reference to FIGS. 2-6, when the user wishes to perform the deflation procedure, the first control switch 4345 of the first regulating lever 434 and the second control switch 4445 of the second regulating lever 444 are rotated to align with the Deflate indication character of the sole 20 as shown in FIG. 11. At this time, the first connecting hole 4343 of the first regulating lever 434 is connected to the other one of the two first connecting pipes 4331 and 4331a of the first oneway valve seat 433, so that the first connecting channel 4342 of the first regulating lever 434 is connected to the first oneway air outlet 432, while the two second connecting holes 4443 and 4443a of the second regulating lever 444 are respectively connected to the air pipe 4433 and the other one of the two second connecting pipes 4431 and

4431a of the second oneway valve seat 443, so that the second connecting channel 4442 of the second regulating lever 444 is connected between the second oneway air outlet 442 and the air pipe 4433 so as to connect the second oneway air outlet 442 with the air pipe 4433. In such a manner, the first air bag

41, the second air bag 42, the first oneway air outlet 432 of the first control valve 43 and the second oneway air outlet 442 of the second control valve 44 are interconnected to form a oneway air outlet space b, so that a oneway air outlet flow channel in turn passes through the first air bag 41, the air nozzle

413, the air pipe 4433, the second connecting channel 4442 of the second regulating lever 444, the other one of the two second connecting pipes 4431 and 4431a of the second oneway valve seat 443, the second oneway air outlet

442 of the second control valve 44, the second outlet pipe 425a, the second air bag 42, the first outlet pipe 424a, the first oneway air outlet 432, the other one of the two first connecting pipes 4331 and 4331a, and the first connecting channel 4342 of the first regulating lever 434. Thus, when the second air bag is stepped by the foot heel 51, the second air bag 42 is contracted to compress the compression elastomer 422, and the air in the second air bag 42 in turn passes through the first outlet pipe 424a, the first oneway air outlet 432, the other one of the two first connecting pipes 4331 and 4331a, and the first connecting channel 4342 of the first regulating lever 434, and is drained outward from the first connecting channel 4342 of the first regulating lever 434 as shown in FIG. 12. On the contrary, when the second air bag 42 is released from the foot heel 51, the second air bag 42 is expanded by the restoring force of the compression elastomer 422 to produce a suction force, and the air in the first air bag 41 is drawn outward and in turn passes through the air nozzle 413, the air pipe 4433, the second connecting channel 4442 of the second regulating lever 444, the other one of the two second connecting pipes 4431 and 4431a of the second oneway valve seat 443, the second oneway air outlet 442 of the second control valve 44 and the second outlet pipe 425a into the second air bag as shown in FIG. 12. In such a manner, the second air bag 42 is contracted and expanded reciprocally by actions of the foot heel 51, so that the first air bag is deflated successively.

Accordingly, the first air bag 41 and the second air bag 42 construct a double airbag structure with a pressure regulating function to cover the user's foot elastically so as to provide a great buffering effect to the user's foot and provide a comfortable sensation to the user. In addition, the first air bag 41 supports the user's foot elastically to release the pressure of the user's foot.

Further, the first air bag 41 is inflated or deflated to support the user's foot ergonomically, without having to provide a shoelace, thereby facilitating the user wearing the shoes. Further, the first air bag 41 is inflated or deflated by operation of the second air bag 42, so that the first air bag 41 encompasses the user's foot exactly to satisfy the ergonomics design. Further, the first air bag 41 is inflated or deflated to fit the foot sizes of different users, thereby enhancing the versatility of the airbag device.
