The present invention relates to a multi-layered airbag installed in shoes characterized by having a structure that at least two unit airbags are combined in multiple layers. The unit airbags are coupled to each other in a partial area between layers. At least one air hole is formed inside each part of the unit airbags, coupled to each other, so air flows between the unit airbags.
