on one of seconds points of positioning 4434 of second tube of mounting 4432. If 1 'we refers to the Figures 7 and 8 with reference to the Figure s 2 to 6, we can see that

operation, when the user wishes to carry out the inflation 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 "Inflated" indicator character on the sole

20, as shown in Figure 7.

At this time, the first connection hole

4343 of the first regulating lever 434 is connected to one of the first two connecting pipes

4331 and 4331a of the first one-way valve seat

433, so that the first connection channel 4342 of the first control lever 434 is connected to the first unidirectional air inlet 431, while the two second connection holes 4443 and 4443a of the second control lever 444 are connected respectively to the air hose 4433 and to one of the two second connection hoses 4431 and 4431a of the second one-way valve seat 443, so that the second connection channel 4442 of the second regulating lever 444 is connected between the second inlet unidirectional air 441 and the air hose 4433 so as to connect the second unidirectional air inlet 441 to the air hose 4433. In this way, the first airbag 41, the second airbag 42, the first inlet one-way air 431 from the first control valve 43 and the second one-way air inlet 441 from the second control valve 44 are interconnected to form an inlet space e of unidirectional air "a", so that a unidirectional air inlet flow channel passes in turn through the first connection channel 4342 of the first regulating lever 434, one of the two first connecting pipes 4331 and 4331a, the first unidirectional air inlet 431, the first inlet pipe 424, the second airbag 42, the second inlet pipe 425, the second unidirectional air inlet 441 of the second control valve 44, one of the two second connecting pipes 4431 and 4431a of the second one-way valve seat 443, the second connecting channel 4442 of the second regulating lever 444, the air pipe 4433, the air nozzle 413 and the first airbag 41. Thus, when the heel of the foot 51 presses on the second airbag 42, the second airbag 42 is caused to contract to compress the elastic means in compression 422, and the air in the second airbag 42 p sits in turn through the second inlet pipe 425, the second unidirectional air inlet 441 of the second control valve 44, one of the two second connecting pipes 4431 and 4431a of the second one-way valve seat 443, the second connection channel 4442 of the second regulating lever 444, the air hose 4433 and the air nozzle 413, to enter the first airbag 41 so as to inflate the first airbag 41. On the contrary, when the foot heel 51 releases the second airbag 42, the second airbag 42 is expanded by the restoring force of the elastic compression means 422 to produce a suction force, and air from the surrounding environment is sucked in inside and passes in turn through the first connection channel 4342 of the first regulating lever 434, one of the first two connection pipes 4331 and 4331a, the first unidirectional air inlet 431 and the first mier inlet pipe 424 in the second airbag 42, as shown in Figure 8. In this way, the second airbag 42 is contracted and extended alternately by actions of the heel of the foot 51, so that the first airbag 41 is successively inflated and is stretched in the reception space 11 of the upper 10 to surround a foot 50.

Referring to Figures 9 and 10 with reference to Figures 2 to 6, it can be seen that when the first control switch 4345 of the first control lever 434 and the second control switch 4445 of the second control lever 444 are rotated to align with the indicator character "Hold" of the sole 20 as shown in Figure 9, the first connection hole 4343 of the first regulating lever 434 is isolated and closed by the wall of the first mounting tube

4332 of the first one-way valve seat 433 to close the first one-way air inlet 431 of the first control valve 43, and the two second connection holes 4443 and 4443a of the second control lever 444 are insulated and closed by the wall of the second mounting tube 4432 of the second one-way valve seat 443 for closing the second one-way air inlet 441 of the second control valve 44.

Referring to Figures 11 and 12 with reference to Figures 2 to 6, it can be seen that, when the user wishes to carry out the deflation procedure, the first control switch 4345 of the first regulating lever 434 and the second control switch 4445 of the second control lever 444 are rotated to align with the indicator character "Deflate" of the sole 20, as shown in Figure 11. At this time, the first connection hole 4343 of the first control lever 434 is connected to the other of the first two connection pipes 4431 and 4331a of the first unidirectional valve seat 433, so that the first connection channel 4342 of the first regulating lever 434 is connected to the first unidirectional air outlet 432, while the two second connection holes 4443 and 4443a of the second regulating lever

444 are connected respectively to the air hose 4433 and the other of the two second connecting pipes

4431 and

4431a of the second one-way valve seat

443, so that the second connecting channel

4442 of the second regulating lever 444 is connected between the second unidirectional air outlet 442 and the air hose 4433 so as to connect the second unidirectional air outlet

442 to air hose 4433.

In this way, the first airbag 41, the second airbag 42, the first unidirectional air outlet 432 of the first control valve 43 and the second unidirectional air outlet 442 of the second control valve 44 are connected between them to form a unidirectional air outlet space "b", so that a unidirectional air outlet flow channel passes in turn through the first airbag 41, the air nozzle 413, the air pipe 4433, the second connection channel 4442 of the second regulating lever 444, the other of the two second connection pipes 4431 and 44431a of the second one-way valve seat 443, the second one-way air outlet 442 of the second control valve 44, the second outlet pipe 425a, the second airbag 42, the first outlet pipe 424a, the first unidirectional air outlet 432, the other of the first two connection pipes 4331 and

4331a, and the first connection channel 4342 of the first regulating lever 434. Thus, when the heel of the foot 51 presses on the second airbag 42, the second airbag 42 is caused to contract to compress the elastic means in compression 422 , and the air in the second airbag 42 passes in turn through the first outlet pipe 424a, the first unidirectional air outlet 432, the other of the first two connecting pipes 4331 and 4331a, and the first channel 4342 of the first regulating lever 434, and is discharged to the outside from the first connecting channel 4342 of the first regulating lever 434, as shown in FIG. 12. On the contrary, when the heel of the foot 51 releases the second airbag 42, the second airbag 42 is expanded by the restoring force of the elastic compression means 422 to produce a suction force, and the air in the first airbag inflates ble 41 is sucked out and passes in turn through the air nozzle 413, the air hose 4433, the second connection channel 4442 of the second regulating lever 444, the other of the two second pipes of connection 4431 and 4431a of the second one-way valve seat 443, the second one-way air outlet 442 of the second control valve 44 and the second outlet pipe 425a, to enter the second airbag 42, as shown in Figure 12 In this way, the second airbag 42 is contracted and extended alternately by actions of the heel of the foot 51, so that the first airbag 41 is successively deflated.

Consequently, the first airbag 41 and the second airbag 42 constitute a double airbag structure with a pressure regulating function to cover the wearer's foot elastically so as to provide the wearer's foot with an effect of 'important cushioning and to provide a feeling of comfort to the user. In addition, the first airbag 41 supports the user's foot elastically to release the pressure from the user's foot. In addition, the first airbag 41 is inflated or deflated to support the user's foot in an ergonomic manner, with laces, thereby facilitating wearing without having to provide shoes for the user.

In addition, the first airbag 41 is inflated or deflated by actuation of the second airbag.

42, such that the first airbag surrounds the wearer's foot in a specified manner, meeting the need for an ergonomic design.
