Abstract
Description
Technical Field
[0001] This utility model relates to a shoe sole structure, and more particularly to a high-heeled shoe cushioning structure that can reduce foot pressure. Background Technology
[0002] In existing technologies, adjustable plantar pressure cushioning structures in high heels primarily alleviate foot pressure through the design of the midsole and insole. The midsole typically uses elastic materials or an air cushion structure to absorb impact and provide cushioning; the insole, through a removable or locally thickened design, adjusts the distribution of plantar pressure. This structure is widely used in daily commutes, business occasions, and special events. Users can choose insoles of different thicknesses or materials as needed and achieve personalized cushioning effects by changing the insole or adjusting the midsole support points during use, thereby improving comfort.
[0003] However, existing technologies still have significant drawbacks. High heels, due to the forward shift of the center of gravity, easily lead to excessive pressure on the forefoot, causing problems such as pain, calluses, and even hallux valgus. Simultaneously, insufficient arch support increases the risk of plantar fasciitis and flat feet, while pressure on the Achilles tendon and ankle joint can easily cause chronic pain and instability. The pointed toe design further compresses the toes, causing corns, neuralgia, and toe deformities. Furthermore, uneven pressure distribution on the sole of the foot not only alters normal gait but may also induce long-term foot diseases, seriously affecting wearing experience and health. These shortcomings indicate that existing technologies still need improvement in terms of functionality and comfort. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a shock-absorbing structure for high heels that can reduce pressure on the soles of the feet.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-heeled shoe cushioning structure that can reduce foot pressure, comprising a midsole and a sole, wherein the midsole and the sole are respectively provided with a forefoot area of the midsole, a forefoot area of the sole, a heel area of the midsole, and a heel area of the sole, corresponding to various parts of the foot. The area between the forefoot area of the midsole and the heel area of the midsole is the main body area of the midsole, and the area between the forefoot area of the sole and the heel area of the sole is the main body area of the sole. The midsole also includes a cushioning pad and a cushioning block. The cushioning pad is disposed in the forefoot area of the midsole and is flush with the surface of the main body area of the midsole facing the sole after installation. One end of the cushioning block is disposed on the heel area of the midsole, and the other end is engaged in the end face of the heel area of the sole corresponding to the heel area of the midsole. The midsole and the sole are positioned by the cushioning block, and after positioning, the corresponding end faces of the midsole and the sole are fitted together.
[0006] The beneficial effects of this invention are as follows: By setting cushioning pads and cushioning blocks in the forefoot and heel areas of the midsole respectively, it can effectively disperse foot pressure and reduce pressure concentration in the forefoot and heel areas, thereby alleviating common foot pain and fatigue problems when wearing high heels. The design of the cushioning pad flush with the forefoot area of the midsole ensures a flat contact surface between the foot and the sole, avoiding discomfort caused by differences in material hardness. The setting of the cushioning block not only enhances the connection stability between the midsole and the insole, but also further improves the cushioning effect through its elastic properties. As a preferred method, the cushioning pad can be made of high-elastic foam material and can be integrally molded with the midsole by injecting liquid material into the mold, ensuring a tight bond between the cushioning pad and the midsole and avoiding material separation problems caused by long-term use. In addition, the snap-fit design of the cushioning block allows the midsole and the insole to fit tightly after being fixed, preventing the insole from shifting and improving wearing comfort and stability.
[0007] Furthermore, the forefoot area of the midsole is provided with a cushioning pad mounting groove. The cushioning pad mounting groove includes a first shallow groove along the edge of the forefoot area of the midsole and a second recess surrounded by the shallow groove. The cushioning pad is provided with a cushioning pad skirt and a cushioning pad mounting protrusion corresponding to the first shallow groove and the first recess, respectively. The cushioning pad skirt and the cushioning pad mounting protrusion cooperate with the first shallow groove and the first recess to form the positioning between the midsole and the cushioning pad.
[0008] By incorporating a cushioning pad mounting groove in the forefoot area of the midsole, and through the coordinated design of the cushioning pad skirt and mounting protrusions with the first shallow groove and second recess, precise positioning of the cushioning pad and midsole is effectively ensured, preventing a decrease in cushioning performance due to pad displacement. The design of the first shallow groove and second recess not only enhances the stability of the cushioning pad but also improves the bonding strength between the cushioning pad and the midsole through its structural characteristics, preventing the cushioning pad from detaching or shifting after long-term use. As a preferred option, the cushioning pad skirt can be made of an elastic material. Its elasticity allows it to fit tightly against the first shallow groove during installation, ensuring a seamless connection between the cushioning pad and the midsole while also creating a transition between the hard and elastic materials to ensure consistent material hardness on the forefoot area of the midsole facing the pad.
[0009] Furthermore, the cushioning pad and the forefoot area of the pad are made of high-elasticity foam.
[0010] The cushioning pad and forefoot area of the sole are made of high-elastic foam, which effectively absorbs the impact of the foot and reduces pressure concentration in the forefoot area, thus alleviating forefoot pain, a common problem when wearing high heels. The high-elastic foam material has excellent resilience and durability, maintaining its cushioning performance over long-term use and preventing a decline in cushioning effectiveness due to material aging. Furthermore, the lightweight nature of the high-elastic foam material reduces the overall weight of the shoe, improving wearing comfort.
[0011] Furthermore, the cushioning pad and the forefoot area of the insole are made of high-elastic foam material, and the cushioning pad and the forefoot area of the midsole are integrally molded.
[0012] The one-piece molding design of the cushioning pad and the forefoot area of the midsole ensures a tight bond between the cushioning pad and the midsole, preventing material separation issues caused by long-term use. This one-piece molding design not only enhances the stability of the cushioning pad but also improves the bonding strength between the cushioning pad and the midsole through its structural characteristics, preventing the cushioning pad from detaching or shifting. Furthermore, the one-piece molding design simplifies the manufacturing process, reduces production costs, and enhances the product's market competitiveness.
[0013] Furthermore, shock-absorbing block mounting grooves are provided on the corresponding end faces of the midsole heel area and the insole heel area. Each shock-absorbing block mounting groove includes a second groove located at its center and a second shallow groove surrounding the second groove. The shock-absorbing block is provided with a shock-absorbing block skirt corresponding to the second shallow groove and the second groove, and shock-absorbing block mounting protrusions are respectively provided on both sides of the shock-absorbing block skirt and protruding from the side of the shock-absorbing block skirt. The depth of each second shallow groove is half of the shock-absorbing block skirt, and the depth of each second groove is equivalent to that of a single shock-absorbing block mounting protrusion.
[0014] By incorporating cushioning mounting slots in the heel areas of the midsole and insole, and through the coordinated design of the cushioning block skirt and mounting protrusions with the second shallow groove and second recess, precise positioning of the cushioning block with the midsole and insole is effectively ensured, preventing a decrease in cushioning performance due to block displacement. The design of the second shallow groove and second recess not only enhances the stability of the cushioning block but also improves the bonding strength between the cushioning block and the midsole and insole through its structural characteristics, preventing the cushioning block from detaching or shifting after long-term use. The cushioning block skirt is also made of elastic material, which, through its elasticity, allows it to fit tightly into the second shallow groove during installation, ensuring a seamless connection between the cushioning block and the midsole and insole. Furthermore, the design of the mounting protrusions further strengthens the connection between the cushioning block and the midsole and insole, preventing loosening due to prolonged use.
[0015] Furthermore, the shock-absorbing block is made of high-elasticity foam.
[0016] The cushioning block is made of high-elasticity foam, which effectively absorbs impact in the heel area, reducing pressure concentration and alleviating heel pain, a common problem when wearing high heels. The high-elasticity foam material has excellent resilience and durability, maintaining its cushioning performance over long-term use and preventing a decline in cushioning effectiveness due to material aging. As a preferred method, the cushioning block can be integrally molded with the midsole and insole by injecting liquid high-elasticity foam into a mold, ensuring a tight bond between the cushioning block and the midsole and insole, preventing material separation due to long-term use. Furthermore, the lightweight nature of the high-elasticity foam material reduces the overall weight of the shoe, improving wearing comfort.
[0017] Furthermore, the main body area and heel area of the padding, excluding the shock-absorbing block mounting groove, are provided with anti-slip textures on the end faces corresponding to the midsole.
[0018] By incorporating anti-slip patterns in the main body and heel areas of the insole, slippage during use is effectively prevented, improving stability and comfort. The anti-slip pattern not only enhances friction between the insole and midsole but also improves insole stability through its structural characteristics, preventing uneven pressure distribution on the foot caused by insole displacement. As a preferred approach, the anti-slip pattern can employ a wave-like or grid-like design, using multi-directional friction to enhance slip resistance and ensure insole stability during use. Furthermore, the anti-slip pattern also increases insole durability, extending its lifespan.
[0019] Furthermore, the main body area of the pad is made of foam material, and the hardness of this material is greater than that of the material of the shock-absorbing pad and the shock-absorbing block.
[0020] The main insole area uses a relatively firm foam material, which effectively provides arch support, alleviating insufficient arch support and reducing arch fatigue and pain. The firm foam material not only provides sufficient support but also enhances the overall stability of the insole through its structural characteristics, preventing uneven pressure distribution on the sole of the foot due to insole deformation. Furthermore, the firm foam material also improves the insole's durability, extending its lifespan.
[0021] Furthermore, auxiliary support parts are provided along the edges of the main body area and the heel area of the pad, and the auxiliary support parts are arc-shaped and used to wrap the user's heel and arch.
[0022] By incorporating curved auxiliary support sections in the main body and heel areas of the insole, the insole effectively wraps around the user's heel and arch, enhancing stability and comfort. The curved auxiliary support design not only provides additional arch support but also improves the insole's fixation through its structural characteristics, preventing uneven pressure distribution caused by insole shifting. Preferably, the auxiliary support section can be made of elastic material, which, through its elasticity, allows it to closely conform to the heel and arch during wear, ensuring stability throughout use.

[0027] This utility model embodiment provides a shock-absorbing structure for high heels that can reduce foot pressure, such as... Figure 1-4 As shown: It includes a midsole 1 and a sole 2. The midsole 1 and the sole 2 are respectively provided with a forefoot area 11 of the midsole, a forefoot area 21 of the sole, a heel area 12 of the midsole, and a heel area 22 of the sole, corresponding to various parts of the sole. The area between the forefoot area 11 and the heel area 12 of the midsole is the main body area 13 of the midsole, and the area between the forefoot area 21 and the heel area 22 of the sole is the main body area 23 of the sole.
[0028] A cushioning pad 3 is provided in the forefoot area 11 of the midsole. After installation, the cushioning pad 3 is flush with the surface of the main body area 13 of the midsole facing the bottom 2. The function of the cushioning pad 3 is to absorb the impact force in the forefoot area, reduce the concentration of pressure in the forefoot, and thus alleviate the forefoot pain problem commonly encountered when wearing high heels. The cushioning pad 3 and the forefoot area 11 of the midsole can be combined by integral molding to ensure a tight bond between the cushioning pad 3 and the midsole 1, avoiding material separation problems caused by long-term use. Alternatively, the cushioning pad 3 can be molded first and then fixed by positioning it with the midsole 1 and then attaching it. In this embodiment, the latter method is used.
[0029] A cushioning block 4 is installed in the heel area 12 of the midsole. One end of the cushioning block 4 is positioned on the heel area 12, and the other end is engaged in the corresponding end face of the heel area 22 of the insole. The function of the cushioning block 4 is to absorb the impact force in the heel area, reduce the concentration of pressure on the heel, and thus alleviate the common heel pain problem when wearing high heels. The engaging design between the cushioning block 4 and the heel areas 12 and 22 effectively prevents the insole from shifting during use, improving stability and comfort.
[0030] The forefoot area 11 of the midsole is provided with a cushioning pad mounting groove 111. The cushioning pad mounting groove 111 includes a first shallow groove 1111 along the edge of the forefoot area 11 and a second recess 1112 surrounded by the shallow groove. The cushioning pad 3 is provided with a cushioning pad skirt 31 and a cushioning pad mounting protrusion 32 corresponding to the first shallow groove 1111 and the second recess 1112, respectively. The cushioning pad skirt 31 and the cushioning pad mounting protrusion 32 cooperate with the first shallow groove 1111 and the second recess 1112 to form the positioning between the midsole 1 and the cushioning pad 3. This design can ensure the precise positioning between the cushioning pad 3 and the midsole 1 and avoid the decrease in cushioning effect caused by the displacement of the cushioning pad 3.
[0031] The cushioning pad 3 and the forefoot area 21 are made of high-elasticity foam, which effectively absorbs the impact of the foot and reduces pressure concentration in the forefoot area, thereby alleviating the forefoot pain commonly encountered when wearing high heels. The high-elasticity foam material has good resilience and durability, and can maintain its cushioning performance during long-term use, avoiding a decrease in cushioning effect due to material aging.
[0032] Both the midsole heel area 12 and the insole heel area 22 have corresponding cushioning block mounting grooves 5 on their end faces. Each cushioning block mounting groove 5 includes a second recess 51 located at its center and a second shallow groove 52 surrounding the second recess 51. Corresponding to the second shallow groove 51 and the second recess 52, the cushioning block 4 is provided with a cushioning block skirt 41 and cushioning block mounting protrusions 42 respectively located on both sides of the cushioning block skirt 41 and protruding from that side. The depth of each second shallow groove 52 is half that of the cushioning block skirt 41, and the depth of each second recess 51 is equivalent to that of a single cushioning block mounting protrusion 42. This design ensures precise positioning of the cushioning block 4 with the midsole 1 and the insole 2, preventing a decrease in cushioning effect due to displacement of the cushioning block 4.
[0033] The insole body area 23 and the insole heel area 22, excluding the cushioning block mounting groove 5, have anti-slip patterns 231 on their corresponding end faces to the midsole 1. The anti-slip patterns 231 prevent the insole from slipping during use, improving stability and comfort. The design of the anti-slip patterns 231 not only enhances the friction between the insole and the midsole 1 but also improves the insole's fixation effect through its structural characteristics, preventing uneven foot pressure distribution caused by insole displacement.
[0034] The main body area 23 of the insole is made of foam material, and the hardness of this material is greater than that of the cushioning pad 3 and the cushioning block 4. The function of the main body area 23 is to provide arch support, alleviate the problem of insufficient arch support, and thus reduce arch fatigue and pain. The relatively hard foam material not only provides sufficient support, but also improves the overall stability of the insole through its structural characteristics, preventing uneven distribution of foot pressure caused by insole deformation.
[0035] An auxiliary support section 232 is provided along the edges of the main insole area 23 and the heel area 22. The auxiliary support section 232 is arc-shaped and is used to wrap around the user's heel and arch. The function of the auxiliary support section 232 is to provide additional arch support, improving stability and comfort when wearing the shoe. The arc-shaped auxiliary support section 232 not only provides additional arch support, but also improves the fixation effect of the insole through its structural characteristics, preventing uneven distribution of foot pressure caused by insole displacement.
[0036] The installation process in this embodiment is as follows: The shock-absorbing pad 3 and the shock-absorbing block 4 are respectively installed in the shock-absorbing pad mounting groove 111 and the shock-absorbing block mounting groove 5 of the midsole 1. At this time, the shock-absorbing block 4 protrudes from the surface of the midsole 1 towards the pad base 2, forming a shock-absorbing block mounting protrusion 42. Then, the shock-absorbing block mounting groove 5 on the pad base 2 is engaged with the aforementioned shock-absorbing block mounting protrusion 42, so that the pad base 2 and the midsole 1 are stably connected through the shock-absorbing block 4 and the anti-slip texture 231 on the pad base 2, thereby forming a detachable fixation between the pad base 2 and the midsole 1. After the pad base 2 has been used for a period of time, it can be replaced by removing the pad base 2.
[0037] It should be noted that the corresponding end faces of the midsole and insole, as well as the end face of the insole corresponding to the user's foot, can be customized according to the curvature of the heel, and both the midsole and insole can be manufactured using a one-piece molding process. The attached diagram shows a flat surface only for ease of depiction and does not represent a limitation on its surface shape.
[0038] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
