[0025] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model technical scheme will be described clearly and completely in combination with specific embodiments of the utility model and corresponding drawings below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] The technical scheme provided by each embodiment of the utility model will be described in detail below in combination with the drawings.

[0027] Referring to Figures 1 to 5 The utility model embodiment provides a shoe midsole that foamed material and big bottom are molded together, including shoe midsole body 1, shoe midsole body 1 includes upper layer 11, middle layer 12 and lower layer 13, upper layer 11, middle layer 12 and lower layer 13 mutually adhere between, be equipped with the placement groove 14 in middle layer 12, the placement groove 14 is equipped with heel cushion structure, arch cushion structure and forefoot cushion structure respectively, three rotation valves that communicate with heel cushion structure, arch cushion structure and forefoot cushion structure are equipped on middle layer 12 respectively.

[0028] First, wear-resistant big bottom is placed on the mold and fixed, then the mold is closed and the injection-molded foamed material and big bottom are injected together, the shoe midsole and big bottom can better fuse during the injection molding process, making the midsole and big bottom become a whole, completely avoiding the situation that the big bottom separates from the midsole, and also reducing a process of big bottom bonding.

[0029] During use, the pressure of the air bags at the forefoot, arch and heel of the foot can be increased or decreased according to the needs of the patient, and the comfort level can be adjusted according to different use conditions or different user conditions.

[0030] When the air pressure is increased, the support is enhanced: it can provide stronger support for the foot, especially for the arch part. This can increase the comfort level for those who need additional support.

[0031] When the air pressure is reduced, the midsole becomes softer when the air pressure of the air bag is reduced. This makes the shoe better fit the shape of the foot during wear, providing more comfortable support for the foot.

[0032] Specifically, the heel cushion structure includes a plurality of equally spaced circular cushion air bags 2; a plurality of the circular cushion air bags 2 are interconnected and connected to the rotary valve.

[0033] The heel is a part that bears a larger impact force when the foot lands, and needs stronger buffering performance. The circular air bag can provide a larger contact area when the foot lands, dispersing the impact force and thereby reducing the pressure on the heel. This shape of air bag can effectively absorb the shock when landing, protecting the heel joint and skeleton, and reducing sports injuries

[0034] Specifically, the arch cushioning structure includes a plurality of long strip-shaped cushioning air bags 3 arranged at equal intervals; the long strip-shaped cushioning air bags 3 are connected to each other and to the rotary valve.

[0035] The long strip-shaped air bags are distributed along the direction of the arch, which can provide support while enhancing the shoe's resistance to torsion. When the foot twists during movement, the long strip-shaped air bag can play a certain limiting role, reducing the risk of sprain. This shape of air bag is suitable for various sports that require frequent changes in direction and turning.

[0036] Specifically, the forefoot cushioning structure includes a plurality of small block-shaped cushioning air bags 4; the small block-shaped cushioning air bags 4 are connected to each other and to the rotary valve.

[0037] The forefoot air bag is designed as multiple small blocks and is distributed according to a certain rule, which can better adapt to the complex stress situation of the forefoot. This design can adapt to different sports movements, such as sudden stops and changes in direction, allowing the air bag to flexibly compress and rebound according to the specific stress points of the foot, providing more accurate support and cushioning, and enhancing the stability and flexibility of the shoe.

[0038] Specifically, the rotary valve is inlaid on the side wall of the midsole 12. The air pressure in the air bag can be increased or decreased through the rotary valve. When wearing the shoe, if it feels too hard, the rotary valve can be opened to release some air pressure, making the shoe softer and more comfortable. When more support is needed, the rotary valve can be closed and air can be injected into the air bag through a special tool to increase the air pressure.

[0039] The above only describes the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
