An air-permeable waterproof device for a shoe has a shoe sole and non-return pieces. Air outlets are disposed at the bottom of the shoe sole, and air vent holes are disposed at the top thereof. Receiving rooms are disposed in the shoe sole and located between the air outlets and air vent holes to connect them together. Bumps are disposed on inner surfaces at the air outlet side of the receiving rooms. The non-return pieces are disposed in the receiving rooms. Foot heat and moisture in a shoe are discharged out from the air vent holes through the air outlets. Exterior water is blocked by the non-return pieces and cannot permeate the shoe through the air vent holes. A filter net is disposed at the shoe sole to prevent the air outlets from being blocked. Moreover, the filter net is skidproof and can absorb moisture in the shoe.
