description A self-lacing system includes an air bag assembly and a vacuum pump respectively attached on an upper portion and a sole portion of the shoe. The vacuum pump includes a first cover and a second cover. A chamber is formed between the first cover and the second cover when the second cover is located at the first position relative to the first cover. Volume of the chamber changes during movement of the second cover relative to the first cover. During the movement of the second cover relative to the first cover, the vacuum pump drives fluid inside the air bag assembly to flow into the chamber via a suction communication channel to collapse an air passage on the air bag assembly for shrinking and reshaping the air bag assembly, which drives the upper portion of the shoe to shrink and reshape for tightening the shoe.
