Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0018] In order to solve the problems existing in the prior art, the present invention provides an insole and its high heel of a shoe, which are attached with a plurality of first air cushions in the heel force-receiving area so as to be exchangeable according to different usage environments and application targets, thereby achieving the purpose of sufficiently dispersing the pressure on the foot.

[0019] In order to make the above objects, features and advantages of the present invention clearer and easier to understand, the present invention will be described in more detail below with reference to the drawings and specific embodiments.

[0020] As shown in FIG. 1, this embodiment provides an insole of a shoe. The insole includes an insole body. Preferably, the entire insole body is made of a thermoplastic material. Specifically, materials such as TPU or ACF can be used. A heel force-receiving area for receiving the force of the heel of the human foot is provided on the insole body. A first recess 3 is provided on the upper surface of the heel force-receiving area. Preferably, the first recess 3 has a laminated plate-like structure, and the structure of the first recess 3 is configured to conform to the structure of the heel of the human foot. Thus, the filling structure in the first recess 3 effectively supports the heel. The opening of the first recess 3 is provided upward, and a plurality of first air cushions 2 that are detachably attached to the inside of the first recess 3 are attached to the first recess 3. The structure of each first air cushion 2 is configured to conform to the structure of the first recess 3, so that the first air cushion 2 fits into the first recess 3. After the insole lining is covered on the upper surface of the insole of the shoe, further restricting the first air cushion 2 ensures that the first air cushion 2 always provides effective support for the heel during use and effectively disperses the pressure. In the specific use process, by replacing different first air cushions 2 according to different usage scenarios and different usage targets, the applicability of the entire insole of the shoe is improved.

[0021] In a specific embodiment, the first air cushion 2 includes a first coating layer having flexibility and conforming to the structure of the first concave portion 3. Preferably, the first coating layer is made of a thermoplastic material, specifically, materials such as TPU or ACF can be used. A first cavity with a laminate structure is provided in the first coating layer, and a first buffer structure is filled in the first cavity. The first coating layer wraps the first buffer structure, further plays a protective role for the first buffer structure, and by combining the first coating layer and the first buffer structure, the pressure dispersion effect of the heel is sufficiently improved. Preferably, the first buffer structure attached to each first air cushion 2 is a laminate structure made of a supercritical material or a silicone rubber material or a thermoplastic material, which improves the support uniformity of the heel. According to different users and usage scenarios, different first air cushions 2 can be selected, that is, the materials of the first buffer structures corresponding to each first air cushion 2 can be utilized. Furthermore, the first coating layer has a transparent structure, so that the user can clearly visually recognize the different first buffer structures made of different materials used in each first coating layer, thereby facilitating the replacement of different first air cushions 2.

[0022] In a specific embodiment, a forefoot sole support area for supporting the forefoot sole of the human foot is provided on the midsole body. A second recess 5 is provided on the upper surface of the forefoot sole support area. Preferably, the second recess 5 has a laminate structure, and the structure of the second recess 5 is configured to conform to the structure of the metatarsal area of the human foot, so that the filling structure in the second recess 5 can effectively support the metatarsal area. The opening of the second recess 5 is provided upward, and a plurality of second air cushions 1 that are detachably attached to the inside of the second recess 5 are attached to the second recess 5. The structure of each second air cushion 1 is configured to conform to the structure of the second recess 5, so that the second air cushion 1 fits into the second recess 5. After the insole is covered on the upper surface of the midsole of the shoe, the second air cushion 1 is further fixed. And after the insole is covered on the upper surface of the midsole of the shoe, by further restricting the second air cushion 1, the second air cushion 1 can always provide effective support for the metatarsal area during use, ensuring the effect of effectively dispersing pressure. Thereby, in the specific use process, by replacing different second air cushions 1 according to different use scenarios and different users, the applicability of the entire midsole of the shoe is improved.

[0023] In a specific embodiment, the second air cushion 1 includes a second covering layer having flexibility and conforming to the structure of the second recess 5. Preferably, the second covering layer is made of a thermoplastic material, specifically, materials such as TPU or ACF can be used. A second cavity with a laminated structure is provided in the second covering layer, and a second buffer structure is filled in the second cavity. The second covering layer wraps the second buffer structure, further plays a protective role for the second buffer structure, and by combining the second covering layer and the second buffer structure, the pressure dispersion effect in the metatarsal area is sufficiently improved. Preferably, the second buffer structure attached to each second air cushion 1 is a laminated structure made of a supercritical material or a silicone rubber material or a thermoplastic material, which improves the support uniformity in the metatarsal area. According to different users and usage scenarios, different second air cushions 1 can be selected, that is, the materials of the second buffer structures corresponding to each second air cushion 1 can be utilized. Furthermore, the second covering layer has a transparent structure, enabling the user to clearly visualize the different second buffer structures made of different materials inside each second covering layer, thereby facilitating the replacement of different second air cushions 1.

[0024] In a specific embodiment, the first air cushion and the second air cushion in the first recess and the second recess can both be replaced with foamed urethane pads according to the usage situation. Here, the structures of the two foamed urethane pads are respectively configured to conform to the structures of the first recess and the second recess, and the foamed urethane pads are made of POROM foam materials.

[0025] In a specific embodiment, the midsole body is further provided with an arch area 4 corresponding to the middle part of the human foot. The arch area 4 is covered with a buffer layer, and the buffer layer plays a role in supporting the main weight of the leg. Preferably, the buffer layer employs an airbag buffer piece.

[0026] The present invention further provides a high heel, which includes a shoe upper and a sole, the sole being provided with an outsole and a midsole located above the outsole, and the upper surface of the midsole being covered with an insole located inside the shoe upper, thereby enabling the midsole to exchange the pressure point of the heel of the high heel and the support pad of the sole of the forefoot, and providing effective support using the arch region 4, thereby improving the cushioning and pressure distribution effects when wearing the high heel.

[0027] Any adaptive changes according to actual needs are within the scope of protection of the present invention.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and may be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention.
