In order to support the weight of the human body, as shown in fig. 2 and 6, a plurality of elastic support columns 14 may be further provided on the bottom surface of the elastic midsole 1 of the shoe.

As shown in fig. 1, an air groove wall 80 is provided in the air chamber 90, the air groove wall 80 divides the air chamber 90 into a rear air chamber 97, a front air chamber 99, an air duct chamber 96, and an island air chamber 98 for making a part of the air groove wall 80 enclosing it exert a starting damping action on the forefoot 70, in other words, "it" in the aforementioned "part of the air groove wall 80 enclosing it" means an island air chamber 98, that is, the air groove wall 80 enclosing the island air chamber 98 can exert a damping action on the forefoot 70 of a person when the person starts, the island air chamber 98 is provided in the front portion of the front air chamber 99, so that the island air chamber 98 is disposed in the range of the front air chamber 99 as if an island, the rear air chamber 97 communicates with the air chamber 98 through the air duct chamber 96, the elastic midsole 1 is formed with the island air chamber 11, the island air chamber 11 is provided at a position corresponding to the island air chamber 98, the island air chamber 11 communicates with the island air chamber 98, and the island air chamber 11 can be provided at a position corresponding to the root of the toes, the wind resistance is lower, so that the blown air flow is stronger, and the ventilation in the shoe is more facilitated. As shown in fig. 2 to 10, the air groove wall 80 includes an elastic male wall 81 and an elastic female wall 82, the elastic female wall 82 includes a first wall 822 and a second wall 823, the first wall 822 and the second wall 823 form a female wall 821, the elastic male wall 81 is in fit, abutting and connection with the female wall 821, an end portion of the elastic male wall 81 and the female wall 821 enclose a cushioning air chamber 824, one of the elastic midsole 1 and the elastic outsole 2 is fixedly and hermetically connected with the elastic male wall 81, and the other is relatively fixedly and hermetically connected with the elastic female wall 82, in other words, the air groove wall 80 can be disposed upside down, and since the elastic midsole 1 and the elastic outsole 2 are soft elastic materials, the rear air chamber 97, the front air chamber 99, the island 98 and the cushioning air chamber 824 can be compressed or restored by their own elasticity.

The operation principle of the present embodiment will be described in detail below: fig. 15 shows a walking gait of a person during walking, in the process from a gait U to a gait W, the heel touches the ground first, then the entire sole touches the ground gradually, when the heel touches the ground, the heel steps on the rear air chamber 97, so that the air in the rear air chamber 97 is squeezed to enter the island air chamber 98 through the air duct chamber 96, and then is ejected from the air vent hole 11 of the island air chamber, the ejected air is favorable for ventilation inside the shoe, so that the foot feels cool, in the process from walking to a gait Z, the sole leaves the ground, the air chamber 90 is reset by its own elasticity, the air is sucked into the rear air chamber 97 from the air vent hole 11 of the island air chamber, the foot continuously walks, the foot periodically obtains a blowing effect, the shoe air is circulated, so that the occurrence of foot odor is favorably reduced, and the health of the foot is favorable. During the processes from gait U to gait W, the air in the shock-absorbing chamber 824 is also squeezed by the end of the elastic male wall 81 and the bottom of the female wall 821 of the elastic female wall 82, because the elastic male wall 81 is in fit and contact with the female wall 821, the air in the shock-absorbing chamber 824 is not easily squeezed out at once, but has a compression process, which reduces the impact force of the ground on the foot, specifically, during the collision between the foot and the ground, the impact force of the ground on the foot is inversely proportional to the duration of the impact force according to the momentum theorem, the process of compressing the air actually prolongs the duration of the impact force of the ground on the foot, so the impact force of the ground on the foot is reduced, meanwhile, the air can be actually used as an elastomer, so the process of compressing the air is also a process of absorbing the shock of the foot, therefore, the present embodiment has a cushioning effect. Then, air is extruded out from between the elastic male wall 81 and the first wall 822 or the second wall 823, and after or while the air in the shock absorbing chamber 824 is extruded out, the elastic male wall 81 and the elastic female wall 82 collide with each other to be elastically deformed, thereby further reducing the impact force of the ground to the foot and facilitating the absorption of the impact shock energy. As shown in fig. 15, this gait is a state that the person just starts or takes a step forward after changing his foot, only the rear sole touches the ground, and the forefoot 70 touches the ground, as shown in fig. 16, at this time, the sole is bent, the front air chamber 99 is partially collapsed, the forefoot 70 can be blocked by a part of the air groove wall 80 near the rear of the island air chamber 98, and this blocking process is elastic buffer blocking, so there is a damping effect, which is favorable for preventing the forefoot 70 from slipping forward relative to the elastic midsole 1 of the shoe, reducing the sliding friction of the forefoot 70, and the relative sliding action of the forefoot 70 and the elastic midsole 1 of the shoe is useless, so that this embodiment can be favorable for preventing the skin damage of the forefoot 70 and also for saving physical strength when walking for a long distance, thus it can be seen that the present invention has significant progress.

Further, as shown in fig. 1, a front vent hole 12 is formed on the inner side of the front portion of the elastic midsole 1, the front vent hole 12 is disposed at a position corresponding to the front air chamber 99, a rear vent hole 13 is formed in the middle portion of the elastic midsole 1, the rear vent hole 13 is disposed at a position corresponding to the front air chamber 99, the rear vent hole 13 is disposed at the outer side of the air duct chamber 96, the front vent hole 12 is disposed at the inner side of the air duct chamber 96, the front vent hole 12 is communicated with the rear vent hole 13 through the front air chamber 99, during the gait V to gait W in fig. 15, the middle portion of the sole is firstly pressed to the middle outer side region of the front air chamber 99, then the forefoot 70 is pressed to the front portion region of the front air chamber 99, when the middle portion of the forefoot is pressed to the middle outer side region of the front air chamber 99, the middle portion of the sole simultaneously closes the rear vent hole 13, and also simultaneously compresses and then compresses and injects compressed air in the front air chamber 99 from the front vent hole 12, the reason why the rear vent hole 13 is provided at the outside of the air duct chamber 96 is that the middle portion of the front air chamber 99 and the area at the inside of the outsole are located corresponding to the arch of the foot, and the portion of the arch is difficult to close the rear vent hole 13 due to the upward arch. When the foot is separated from the ground, the front air chamber 99 is elastically restored by itself, thus being disposed to further facilitate the air circulation inside the shoe.

Furthermore, one of the elastic midsole 1 and the elastic outsole 2 is integrally formed with the elastic male wall 81, and the other is integrally formed with the elastic female wall 82, so that in the assembly process of the sole, the assembly of the air groove wall 80 can be completed only by simple male and female insertion actions, and the assembly process of the sole is facilitated.

In some embodiments, one of the elastic midsole 1 and the elastic outsole 2 is bonded to the elastic male wall 81, and the other is bonded to the elastic female wall 82, so that the present embodiment can be bonded by appropriately adjusting the position of the air groove wall 80 according to the actual foot shape of the user, and flexibility is good.

In some embodiments, as shown in FIG. 2, island air cavity 98 has a circular shape, which advantageously reduces airflow resistance and allows airflow to better exit from island air cavity vents 11.

In some embodiments, as shown in FIG. 18, island air chambers 98 are rectangular in shape and air channel walls 80 enclosing rectangular island air chambers 98 are relatively flat and provide a significant amount of damping to forefoot 70.

In some embodiments, as shown in fig. 11, the second wall 823 is higher than the first wall 822, so that when the elastic midsole 1 of the shoe is pressed down, the first wall 822 is touched first, and then the two walls are touched at the same time, the impact buffering effect is increased from weak to strong, which is beneficial to better feeling of the sole of the foot when a person walks.

In some embodiments, as shown in fig. 10, the end portions of the elastic male wall 81, the first wall 822 and the second wall 823 are formed to be flat-topped, or to be symmetrical and sharp-angled as shown in fig. 12, or to be semicircular as shown in fig. 14, or to be wedge-shaped as shown in fig. 13, that is, the end portions of the elastic male wall 81, the first wall 822 and the second wall 823 are formed to be freely combinable, and only some combinations are illustrated in the drawings, the structure of fig. 10 has a strong initial buffering effect, while the structures of fig. 12, 13 and 14 can make the buffering effect from weak to strong, which is beneficial for better feeling of sole when a person walks. When the end portions of the first wall 822 and the second wall 823 are in the wedge shape, the inclined surfaces of the first wall 822 and the second wall 823 are arranged oppositely, and the effect of guiding when the elastic midsole 1 and the elastic outsole 2 of the shoe are assembled is also achieved.

In some embodiments, as shown in fig. 19, the air duct cavity 96 is provided with a damping wall 83 on each side thereof for generating an anti-slip function on the sole 70, the damping wall 83 is fixedly connected to one of the elastic outsole 2 and the elastic midsole 1, or the damping wall 83 is fixedly connected to both the elastic outsole 2 and the elastic midsole 1. The damping wall 83 may be of similar construction and connection to the air channel wall 80 or may be of simple single wall construction. When a person goes up a slope, the sole of the foot is easy to slip on the elastic midsole 1, and at this time, corresponding to the gait X in fig. 15, after the forefoot 70 collapses the forefoot air chamber 99, as shown in fig. 20, the damping walls 83 can play a role of damping the forefoot 70, which is beneficial to preventing the sole from slipping on the elastic midsole 1.

The soles in the above figures are all corresponding to the left foot, and for the right sole, the description is omitted here because it is only the left-right symmetrical relation.

Meanwhile, the invention also provides a shoe adopting the embodiment, which comprises the sole, wherein the shoe elastic outsole 2 or the shoe elastic midsole 1 is connected with the upper 3, the upper 3 and the shoe elastic midsole 1 enclose a wearing cavity of the shoe, and the shoe is provided with the sole, so that the shoe has the beneficial effect of the sole.
