When a user wears shoes made of the breathable shoe soles and walks, when a plurality of groups of columnar one-way valves 10 at the heel end 3 of the breathable shoe midsole 30 are under the pressure of the heel, the pressurized airflow flows out through the open end of the lower side conical elastic cavity 27 and opens the pressure sensing film vertical pipe 29 at the closed end of the lower side conical elastic cavity 27, so that the air in the elastic columnar valve body 22 is exhausted from the heel side exhaust holes 7 at the two sides of the heel end 3 through the air hole channel. Meanwhile, when the heel part is lifted, the lower side conical elastic cavity 27 is restored, and the pressure sensing film vertical pipe 29 is closed along with the lower side conical elastic cavity; and the air in the shoe enters the air inlet hole 6 at the heel part of the sole under the action of atmospheric pressure and flows in through the opening end of the upper side conical elastic cavity 26 of the columnar one-way valve 10, so that the pressure sensing film vertical pipe 29 at the closed end of the upper side conical elastic cavity 26 is opened, and the air is supplemented into the columnar one-way valve 10 through the air inlet hole 6 at the heel part of the sole to form the one-way flow of the air flow in the shoe chamber and at the rear part.

Similarly, when the transition air bag cavity 8 and the plurality of groups of flat one-way valves 9 at the front sole end 2 of the breathable insole 30 are subjected to the pressure of the sole, the pressurized air flows out through the open end of the outer fish-mouth-shaped elastic cavity 18, and the flat mouth 20 of the pressure-sensitive film at the closed end of the outer fish-mouth-shaped elastic cavity 18 is opened, so that the air in the elastic flat valve body 13 is exhausted from the front sole side exhaust holes 5 at the two sides of the front sole end 2. When the sole part is lifted, the outer fish-mouth-shaped elastic cavity 18 is restored to the original state, and the pressure-sensitive film flat opening 20 is correspondingly closed; meanwhile, the air entering the transition air bag cavity 8 through the air inlet hole 4 at the front part of the sole flows in through the opening end of the inner fish-mouth-shaped elastic cavity 17 of the flat one-way valve 9 under the action of atmospheric pressure, and the flat opening 20 of the pressure-sensitive film at the closed end of the inner fish-mouth-shaped elastic cavity 17 is opened, so that the air in the transition air bag cavity 8 is supplemented into the flat one-way valve 9, and the unidirectional flow of the air flow in the shoe chamber and the front part is formed. Furthermore, the process of air suction and exhaust in the shoe is completed by utilizing the circulating pressure of the foot of a user during normal walking, so that the unidirectional smooth flow of fluid inside and outside the shoe is realized, the moisture and the water in the sole are quickly exhausted, the damp and hot closed environment in the shoe is improved, and the use comfort of the bottom of the foot is improved.
