The heel part of the cavity is the heel cavity 4, and the heel cavity 4 is provided with a heel bag 7. The heel bag 7 also includes an opening 502 and a one-way air intake component 701 provided on the opening 502. The midsole 2 is provided with an airbag pressure cover 8 that cooperates with it. The heel cavity 4 and the cavity 3 are connected by an exhaust groove 9. The midsole 2 is provided with air vents to connect the inner cavity of the shoe and the cavity 3. The outsole 1 corresponding to the heel bag 7 is also provided with micro exhaust holes 6. The micro exhaust holes 6 are usually so small that they cannot be seen by the naked eye. They are also called invisible exhaust holes. The micro exhaust holes 6 allow the gas to be discharged outward only under pressure and are waterproof. The air vents, cavity 3 (or heel cavity 4), airbag 5 (or heel cavity 4) and micro exhaust holes 6 constitute an exhaust channel. In this embodiment, the V-shaped notch 504 for one-way exhaust is prior art, and its structure is disclosed in the Chinese patent publication number CN101352273A, which will not be repeated here. The heel bag, one-way air intake assembly and corresponding air bag gland structure are also prior art, and are also disclosed in the conflicting application No. 2022108405034 and the patent technical documents of the same applicant before the application date of this application. Figure 4 and Figure 10 The structures of the two heel capsules are shown in detail. Figure 4In one structure, the heel bladder is provided with a reserved hole, the heel bladder cover is arranged above the reserved hole, the one-way air permeable component 701 is integrally formed with the heel bladder cover as an elastic closure part recessed into the reserved hole of the air bladder, a cut is reserved on the elastic closure part, the cut is dislocated to form an air inlet channel when the elastic closure part is pressed, and the heel bladder cover further comprises a support column extending into the air bladder. Figure 10 Another structure of the heel bladder is disclosed, the one-way air permeable component 701 forms an elastic closure part recessed into the air bladder and is integrally formed with the heel bladder as a separate component made of elastic material, a cut is reserved on the elastic closure part, and the heel bladder is fixed at the corresponding groove of the heel sole by means of gluing or buckling connection. The difference between the two structures is that, Figure 4 the structure of the heel bladder and the one-way air permeable component in the above embodiment 1 belong to two independent components forming a combined structure, and Figure 10 the structure of the heel bladder and the one-way air permeable component in the above embodiment 2 belong to an integral structure. In addition, it should be noted that the shape of the one-way air inlet component 701 and the heel bladder can be circular, oval, and polygonal, and the air inlet channel thereof can be provided with one or multiple air inlet channels.

[0032] In the above embodiment 1, the material for manufacturing the air bladder cover 503 can be the same as that of the air bladder 5, both of which are elastic materials, or the material for the air bladder cover 503 is less elastic than that of the air bladder 5, and the air bladder cover 503 can be fixed by tight fitting contact or gluing.

[0033] In the above embodiment 1, referring to Figure 1 and 3 , a plurality of transverse reinforcing ribs 10 are further included, the reinforcing ribs are made of elastic material and are integrally formed with the sole, the cavity 3 of the present application extends to the edge of the sole 1, the reinforcing ribs are used to reinforce the support ability and shock absorbing performance of the forefoot, and the heel cavity 4 is provided with a reflective reinforcing rib. As Figure 1As shown, the transverse reinforcing rib 10 is broken around the air bag 5 of the forefoot to form an air passage 11, the air bag 5 of the forefoot is arranged in the middle of the air passage 11, and the transverse reinforcing rib 10 on both sides of the air bag 5 is extended to make the air passage 11 contract, the exhaust groove 9 is arranged opposite to one transverse reinforcing rib 10 near one end of the forefoot cavity 3, and the air guide block 12 is arranged on both sides of the front end of the exhaust groove 9. In the embodiment, the front and back sides of the air bag 5 refer to the front side of the air bag 5 towards the head of the sole and the back side of the air bag 5 towards the heel. When the air in the forefoot flows to the heel cavity 4, the air flows along the air passage 11, the position of the air bag 5 has the function of blocking and guiding, the air flow forms a vortex, part of the air flow is blocked and guided into the cavity between the transverse reinforcing ribs 10 and then flows along the cavity and enters the air passage 11 again, thereby increasing the resistance of the air flowing from the cavity 3 to the heel, reducing the air flow rate, and also mixing in the cavity 3 separated by the reinforcing ribs, so that the air in the cavity 3 can be fully replaced, avoiding the air in some areas not being replaced for a long time and producing odor. In the embodiment, because the heel lands first when walking, then the forefoot lands, and then the heel is lifted first when lifting, at this time, the heel bag 7 forms a negative pressure, the forefoot forms a positive pressure, the air in the forefoot flows to the back under the action of a large pressure difference, at this time, limited by the contraction of the exhaust groove 9, the air flow rate can reach a very high speed, the pressure of the forefoot decreases rapidly, the supporting property decreases rapidly, and the high air flow rate is also easy to produce abnormal sound, the above structure of the embodiment can reduce the air flow rate, so that the forefoot provides effective support in the short time from the heel landing to the forefoot lifting, effectively avoiding the above situation. In the embodiment, after the forefoot lands, according to the design intention, the air in the cavity 3 flows from the forefoot to the heel bag through the air passage, because the cavity 3 is communicated with the shoe cavity, this process depends on the human foot front part stepping on the sole to close the air holes on the insole or the cushioning bottom, because of individual differences, this way of closing depending on the contact between the foot bottom and the sole has great uncertainty, that is, the technical solution cannot always achieve the ideal effect, of course, in the above solution, the problem can be solved by arranging a one-way valve on the insole or the cushioning bottom, but arranging the one-way valve increases the cost and the complexity of assembly, for reference Figure 11 As shown, the transverse reinforcing rib 10 is broken around the air bag 5 of the forefoot to form an air passage 11, the air bag 5 of the forefoot is arranged in the middle of the air passage 11, and the transverse reinforcing rib 10 on both sides of the air bag 5 is extended to make the air passage 11 contract, the exhaust groove 9 is arranged opposite to one transverse reinforcing rib 10 near one end of the forefoot cavity 3, and the air guide block 12 is arranged on both sides of the front end of the exhaust groove 9. In the embodiment, the front and back sides of the air bag 5 refer to the front side of the air bag 5 towards the head of the sole and the back side of the air bag 5 towards the heel. When the air in the forefoot flows to the heel cavity 4, the air flows along the air passage 11, the position of the air bag 5 has the function of blocking and guiding, the air flow forms a vortex, part of the air flow is blocked and guided into the cavity between the transverse reinforcing ribs 10 and then flows along the cavity and enters the air passage 11 again, thereby increasing the resistance of the air flowing from the cavity 3 to the heel, reducing the air flow rate, and also mixing in the cavity 3 separated by the reinforcing ribs, so that the air in the cavity 3 can be fully replaced, avoiding the air in some areas not being replaced for a long time and producing odor. In the embodiment, because the heel lands first when walking, then the forefoot lands, and then the heel is lifted first when lifting, at this time, the heel bag 7 forms a negative pressure, the forefoot forms a positive pressure, the air in the forefoot flows to the back under the action of a large pressure difference, at this time, limited by the contraction of the exhaust groove 9, the air flow rate can reach a very high speed, the pressure of the forefoot decreases rapidly, the supporting property decreases rapidly, and the high air flow rate is also easy to produce abnormal sound, the above structure of the embodiment can reduce the air flow rate, so that the forefoot provides effective support in the short time from the heel landing to the forefoot lifting, effectively avoiding the above situation. In the embodiment, after the forefoot lands, according to the design intention, the air in the cavity 3 flows from the forefoot to the heel bag through the air passage, because the cavity 3 is communicated with the shoe cavity, this process depends on the human foot front part stepping on the insole or the cushioning bottom to close the air holes, because of individual differences, this way of closing depending on the contact between the foot bottom and the sole has great uncertainty, that is, the technical solution cannot always achieve the ideal effect, of course, in the above solution, the problem can be solved by arranging a one-way valve on the insole or the cushioning bottom, but arranging the one-way valve increases the cost and the complexity of assembly, for reference
