Ventilated footwear comprises an outer sole having a hollow portion forming an air pumping chamber at its heel portion, a plurality of ventilation holes provided on an inner sole within the range of the air pumping chamber, a cushioning material having cells therein to contain air being spread over an upper surface of the inner sole on the heel part thereof, projections projecting from the outer sole forming cavities between the outer sole and the inner sole, the cavities functioning as an air chamber, a plurality of ventilation holes provided on the inner sole and ducts longitudinally provided between the inner sole and the outer sole so as to communicate the air pumping chamber and the cavities. When the weight of the wearer is applied to the heel part, the ventilation holes are closed and the cushioning material is depressed so as to forcibly send air from the chamber to the cavities through the ducts and when the weight of the wearer is applied to the front area of the shoe, the projections are depressed and deformed so as to force air into the inner part of the shoe through the ventilation holes.
