When the front sole and the rear sole slide downward, the shock absorption airbag will be pulled by the fixed column, so that the air pushes the sealing plate through the air intake pipe and enters the shock absorption airbag. When the front sole and the rear sole fall to the ground, the front sole and the rear sole slide upward. When sliding, the front sole and the rear sole will squeeze the shock absorption airbag through the fixed column. At this time, the air in the shock absorption airbag will be slowly discharged through the exhaust hole, so as to realize buffering and shock absorption of the shoe body and improve the wearing comfort of the shoe body.

[0015] In addition, through the setting of the tightening mechanism, the tightening of the shoelaces is achieved. When the shoelaces need to be tightened, the pressing block can be pushed by the toe of the other foot, so that the pressing block drives the connecting ratchet to rotate through the engagement of the fixed rack and the gear ring. The rotation of the connecting ratchet will drive the connecting wheel to rotate under the action of the connecting pawl. The rotation of the connecting wheel will drive the wire roller to rotate through the fixed square rod under the action of the sliding connection between the square groove and the connecting square block, so that the wire roller tightens the shoelaces. The operation is simple, the use efficiency is improved, and the user experience is improved.

[0016] In addition, through the setting of the above-mentioned mechanism, shock absorption and buffering of the shoe body are achieved, the wearing comfort of the shoe body is improved, and the shoelaces are tightened, which improves the use efficiency and the use experience.
