    Abstract: The present invention is to provide a ventilated shoe comprising a hollow heel formed of plastic material, which comprises an enclosed bladder being divided into a left bladder section and a right bladder section; an outsole; a vamp comprising a blood vessel-like line of fresh air connected to the left bladder section through a first check valve and a blood vessel-like line of foul air connected to the right bladder section through a second check valve; an insole; an inflow hose connected to the left bladder section; and an outflow hose connected to the right bladder section. Thus, by repeating a cycle of lifting a foot wearing the shoe and setting the foot down, fresh air is adapted to continuously suck into the shoe via the left bladder section and foul air is adapted to continuously drive out of the shoe via the right bladder section so as to bring a degree of comfort to the foot.
