Description

Technical Field

[0001] The present application relates to the technical field of footwear, and in particular to an insole. Background Art

[0002] Custom orthotic / rehabilitation insoles are tailored to the individual's foot characteristics and needs. They are designed to provide extra support and stability to help correct foot posture and improve gait. These insoles can be customized to provide personalized support and comfort based on arch height, foot shape, and foot problems such as flat feet, high arches, and valgus feet. Custom orthotic / rehabilitation insoles can reduce foot discomfort and pain and improve gait, which can be very helpful for people who need extra foot support.

[0003] In related technologies, such as Figure 1 As shown, the customized correction / rehabilitation insole includes an insole bottom 10 and a fabric 11. The insole bottom 10 is 3D printed or 3D carved using hard materials, such as nylon, TPU, etc., and has sufficient strength and rigidity to achieve gait posture correction and additional support, and is printed or carved into an insole shape that fits the foot shape according to the user's foot shape data. The fabric 11 uses soft, breathable materials, such as fabric, leather, etc., and has good moisture absorption and perspiration function, keeps the foot dry and comfortable, provides additional comfort, and reduces friction and discomfort.

[0004] However, the customization time of 3D printed or engraved insoles is relatively long. It takes 40 minutes to print or engrave a single insole, and 80 minutes to print a pair, which often cannot meet the timeliness requirements of users. In addition, existing customized correction / rehabilitation insoles often cause users to feel more uncomfortable. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related art, the present application provides an insole that can reduce the discomfort caused to the user.

[0006] A first aspect of the present application provides an insole, comprising: a base layer, a module layer and a surface layer, wherein the surface layer is stacked on the base layer, the module layer is located between the surface layer and the base layer, and the module layer is connected to the surface layer and the base layer respectively; the module layer comprises a first support module located below the inner side of the calcaneus, the first support module is arranged opposite to the talus in the longitudinal direction, and the first support module supports the calcaneus and / or the talus upward.

[0007] A second aspect of the present application provides an insole, comprising: a base, a supporting surface of the base for supporting a human foot being provided with a first support module, the first support module being integrally formed with the base; the first support module being located below the inner side of the calcaneus, the first support module being arranged opposite to the talus in the longitudinal direction, and the first support module supporting the calcaneus and / or the talus upward.

[0008] The technical solution provided by the present application may include the following beneficial effects: the first support module can support the calcaneus, the talus, or both the calcaneus and the talus. Compared with the 3D insoles in the prior art that only support the arch area, the insoles of the present application can reduce the discomfort caused to the user, and have a better effect on calcaneal flipping and improving flat feet.

[0009] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] An embodiment of the present application provides an insole that can shorten the customization time of the insole.

[0042] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0043] Figure 2 This is a top view of the human left foot bones. Figure 3This is a side view of the bones of the human right foot. Figure 4 is a three-dimensional diagram of an insole shown in an embodiment of the present application, Figure 5 yes Figure 4 An exploded view of the insole is shown, wherein Figure 4 Shown is the insole for the left foot.

[0044] like Figure 4 and Figure 5 As shown, the embodiment of the present application provides an insole, comprising a base layer 20, a module layer 30 and a surface layer 40, wherein the surface layer 40 is stacked on the base layer 20, the module layer 30 is located between the surface layer 40 and the base layer 20, and the module layer 30 is connected to the surface layer 40 and the base layer 20 respectively. The shapes of the base layer 20 and the surface layer 40 generally match the sole of the shoe. When the insole is placed in the user's shoe, the base layer 20 is located below the surface layer 40 and is used to contact the sole of the shoe, the surface layer 40 is used to contact the user's foot, and the module layer 30 is located between the surface layer 40 and the base layer 20, so that the corresponding part of the surface layer 40 is raised. When the user steps on the surface layer 40, the raised parts of the surface layer 40 and the module layer 30 relative to each other can support the user's foot upward, thereby playing a certain correction role. It is understandable that the module layer 30 is provided at the position where upward raised support is required for the foot, while the module layer 30 may not be provided at other positions. For the position where there is no module layer 30 between the base layer 20 and the surface layer 40, the base layer 20 and the surface layer 40 are connected.

[0045] The base layer 20, the module layer 30 and the surface layer 40 can all be made of EVA, foam or PU material. Preferably, the base layer 20 and the module layer 30 are both made of EVA material, and the base layer 20, the module layer 30 and the surface layer 40 can be made to have a suitable hardness as required.

[0046] Figure 6 yes Figure 4 A top view of the module layer and the base layer 20 of the insole is shown. Figure 7 yes Figure 4 A three-dimensional view of the first support module of the insole is shown. Figure 6 and Figure 7 As shown, the module layer 30 includes a first support module 31 located below the inner side of the calcaneus. The first support module 31 is arranged opposite to the talus in the longitudinal direction, and the first support module 31 supports the calcaneus and / or the talus upward. The first support module 31 can be made of EVA, foam or PU material, preferably made of EVA material. The first support module 31 is located between the base layer 20 and the surface layer 40, and is connected to the base layer 20 and the surface layer 40 by bonding or suturing, so that it will not move relative to the base layer 20 and the surface layer 40.

[0047] By setting the module layer 30 between the surface layer 40 and the base layer 20, the first support module 31 in the module layer 30 can be pre-set to a variety of different models. The first support module 31 of a suitable model is selected according to the user's foot shape, plantar pressure data, etc., and the first support module 31 is connected to the base layer 20 and the surface layer 40 to form an insole. Compared with using 3D printing or engraving, the customization time of the insole is shortened.

[0048] The first support module 31 can be used to correct flat feet. The first support module 31 is located below the inner side of the calcaneus. Figure 5 and Figure 7 As shown, the upper side of the first support module 31 is convex upward, and the convex part supports the corresponding part of the sole of the foot upward. In this way, the first support module 31 supports the calcaneus upward, which can reduce the medial gap between the calcaneus and the talus, thereby correcting flat feet. Specifically, as shown in FIG. Figure 3 As shown, when the foot is flat, the calcaneus will turn down to the inside of the calcaneus compared to the normal foot shape. The downward turning of the calcaneus will cause the arch area of ​​the foot to collapse (flat feet) and the heel to turn outward. The first support module 31 supports the calcaneus upward to turn the inside of the calcaneus upward, thereby driving the arch area of ​​the foot upward, improving the collapse of the arch area and the heel to turn outward. In the embodiment of the present application, the inside refers to the side where the big toe of the foot is located, and the outside refers to the side where the little toe of the foot is located.

[0049] like Figure 3 As shown, the support point in the figure is the main force point of the first support module 31 on the calcaneus, and the support point is located at the talar process of the calcaneus, that is, the first support module 31 supports the talar process of the calcaneus upward.

[0050] In other embodiments, the first support module 31 may also support the talus upward, so that the talus drives the inner side of the calcaneus to turn upward, and also drives the arch area of ​​the foot upward, thereby improving the collapse of the arch area and heel eversion.

[0051] In other embodiments, the first support module 31 can also support the calcaneus and the talus at the same time, so as to disperse the support force of the first support module 31 and reduce the discomfort caused by the first support module to the user. Specifically, the first support module 31 can support the talar process of the calcaneus and the talus at the same time.

[0052] For flat feet, the 3D insoles in the prior art only support the arch area, for example, only support the area of ​​the navicular bone and the cuneiform bone, which will cause the navicular bone and the cuneiform bone to flip upward, making the pain more obvious, and the effect of the navicular bone and the cuneiform bone flipping upward to drive the calcaneus to flip upward is not good. The first support module 31 in the embodiment of the present application can support the calcaneus, the talus, or support the calcaneus and the talus at the same time. Compared with the prior art, it can reduce the discomfort brought to the user, and the effect of the calcaneus flipping upward is better, and the effect of improving flat feet is better.

[0053] In some embodiments, the first support module 31 can be pre-produced with some different models so that the model that matches the user can be selected when customizing the insole. For example, the first support module 31 has 3 preset heights (height levels 1, 2, 3, the higher the value, the higher), 3 hardnesses (hardness levels 1, 2, 3, the higher the value, the harder), and a total of 9 options after combination. If user A has severe flat feet, the first support module 31 with the highest height level 3 and hardness level 3 is used to pad the inner side of the heel bone; a staged correction method can also be used, with the height and hardness levels from low to high, and the user is divided into several stages for step-by-step correction.

[0054] In some embodiments, the upper surface of the first support module 31 protrudes upward, and the highest part of the upper surface of the first support module 31 supports the talar process of the talus and / or calcaneus. In this way, after the sole of the foot steps on the insole, the highest part of the upper surface of the first support module 31 serves as the main force-bearing part of the support, supporting the talar process of the talus and / or calcaneus upward, thereby correcting flat feet.

[0055] Specifically, Figure 7 As shown, the upper surface of the first support module 31 is an arc-shaped structure that bulges upward, and the arc-shaped structure is an upward arch. The height of the first support module 31 gradually decreases from the inner side to the outer side of the foot to fit with the calcaneus and talus. The highest part of the upper surface of the first support module 31 is the highest point of the arch, and the lower surface of the first support module 31 is a flat structure, which is convenient for fitting with the base layer 20. The highest part of the arc-shaped structure can support the talar process of the calcaneus and / or the talus, while the other parts of the arc-shaped structure can also support the scaphoid bone and the cuneiform bone. The first support module 31 only has the highest point at the talar process of the calcaneus and / or the talus.

[0056] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the module layer 30 also includes a second support module 32, which is located below the outer side of the calcaneus and opposite to the first support module 31, and the upper surface of the second support module 32 is convex upward. The second support module 32 can be made of EVA, foam or PU material, preferably EVA material. The second support module 32 is located between the base layer 20 and the surface layer 40, and is limited by the base layer 20 and the surface layer 40 so as not to move relative to the base layer 20 and the surface layer 40.

[0057] Because the support force of the first support module 31 causes the foot to have an outward tilting pressure, the second support module 32 can make the outward tilting pressure return to the inner side of the calcaneus, so that the calcaneus is balanced on the correct force line. The upper surface of the second support module 32 bulges upward and supports the outer side of the calcaneus upward, thereby returning the outward tilting pressure to the inner side of the calcaneus. Specifically, the second support module can be an upwardly arched arc structure, and the height of the second support module 32 gradually decreases from the outer side to the inner side, so as to fit the outer side of the calcaneus.

[0058] Specifically, the second support module 32 can have 3 heights (height levels 1, 2, 3, the higher the value, the higher), 2 materials (hardness levels 1, 2, the higher the value, the harder), and a total of 6 options. If user A has severe flat feet and the pressure distribution of the medial calcaneal area is weak, the second support module 32 with height level 2 and hardness level 2 can be selected, so that the pressure is tilted to the medial calcaneus, so that the calcaneus is balanced on the correct force line and the force on the lateral calcaneus is dispersed.

[0059] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, the module layer 30 also includes a third support module 33a, which is used to support at least the outermost metatarsal. Specifically, the third support module 33a can support the first metatarsal, the first and second metatarsal, the first to third metatarsal, or the first to fourth metatarsal from the outer side to the inner side of the foot. The third support module 33a is an auxiliary module for the outer side of the palm. After the foot is supported by the first support module 31, the force on the palm position is reduced and the force on the outer side is increased. The third support module 33a can evenly distribute some of the pressure on the outer side of the metatarsal to the inner side of the metatarsal, thereby maintaining a relative balance of force.

[0060] The upper surface of the third support module 33a is raised upward, thereby supporting the corresponding metatarsal upward. The third support module 33a can be made of EVA, foam or PU material, preferably EVA material. The third support module 33a is located between the base layer 20 and the surface layer 40, and is limited by the base layer 20 and the surface layer 40 so as not to move relative to the base layer 20 and the surface layer 40.

[0061] In this embodiment, the third support module 33a can support the metatarsal bones corresponding to the other four toes except the big toe. Optionally, the third support module 33a has two heights (height level 1, 2, the higher the value, the higher), two materials (hardness level 1, 2, the higher the value, the harder), and a total of four options. For example, after user A uses the first support module 31, the palm position is suspended in the air, and the force on the outside increases. In this case, the third support module 33a with a height level of 2 and a hardness level of 1 can be selected to raise it, so that the pressure on the outside of the metatarsal bones is evenly distributed to the inside of the metatarsal bones to maintain relative balance.

[0062] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Fig.10 As shown, the module layer 30 also includes a fourth support module 34a, which is used to support at least the outermost phalanges. Specifically, the fourth support module 34a can support the first phalanges, the first and second phalanges, the first to third phalanges, or the first to fourth phalanges from the outer side to the inner side of the foot. After the foot is supported by the first support module 31, the pressure on the outer side of the forefoot increases, and the fourth support module 34a is a forefoot auxiliary module, which is used to distribute some of the pressure on the outer side of the forefoot to the inner side of the forefoot to maintain a relative balance of force.

[0063] Optionally, the fourth support module 34a has two heights (height level 1, 2, the higher the value, the higher), and two materials (hardness level 1, 2, the higher the value, the harder), for a total of four options. For example, after using the first support module 31, when the gait pressure of user A is too concentrated on the outer side of the forefoot, the fourth support module 34a with height level 2 and hardness level 1 can be selected for padding, so that the pressure on the outer side of the forefoot is evenly distributed to the inner side of the forefoot to maintain relative balance.

[0064] In some embodiments, Fig.10 As shown, the height of the fourth support module 34a gradually decreases from the outside to the inside to adapt to the distribution of the pressure at the forefoot corresponding to the phalanges gradually decreasing from the outermost phalanges to the inner phalanges, so that the forefoot is more evenly stressed.

[0065] Figure 4 In the illustrated embodiment, the fourth support module 34a can support the phalanges corresponding to the other four toes except the big toe, and the height of the fourth support module 34a gradually decreases from the outside to the inside to adapt to the distribution of forefoot pressure gradually decreasing from the outermost phalanges to the inner phalanges, so that the forefoot force is more evenly distributed.

[0066] Fig.11 is a three-dimensional diagram of an insole according to another embodiment of the present application, Fig.12 yes Fig.11An exploded view of the insole is shown, Fig.13 yes Fig.11 A perspective view of the fourth support module of the insole is shown. Figures 11 to 13 As shown, Fig.10 The difference between the embodiments is that in some embodiments, the height of the fourth support module 34b gradually decreases from the inside to the outside. Specifically, when the user has severe flat feet, which may be accompanied by hallux valgus symptoms, when the height of the fourth support module 34b gradually decreases from the inside to the outside, the inside of the fourth support module 34b is higher, so that the big toe can be separated from other fingers, and the force on the big toe area is dispersed, the discomfort of the big toe is relieved, and the correction and customization functions of the hallux valgus and flat foot group can be met.

[0067] In some embodiments, Figures 4 to 6 As shown, there is a containing gap 50 between the fourth supporting module 34a and the third supporting module 33a, so that the joint between the phalanges and the metatarsals is located in the containing gap 50. There is a certain distance between the fourth supporting module 34a and the third supporting module 33a on the base layer 20, forming a concave containing gap 50, and the joint between the phalanges and the metatarsals is located in the containing gap 50, thereby dispersing the force of the joint between the phalanges and the metatarsals, and avoiding pain in the joint between the phalanges and the metatarsals when walking.

[0068] In some embodiments, Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, the height of the third support module 33a gradually decreases from the outside to the inside to adapt to the distribution of the forefoot pressure gradually decreasing from the outermost metatarsal to the inner metatarsal, so that the forefoot force is more evenly applied.

[0069] In some embodiments, Figure 4 As shown, the base layer 20 includes a buffer layer 21 and a support layer 22, the support layer 22 is stacked on the upper surface of the buffer layer 21, and the module layer 30 is arranged on the upper surface of the support layer 22. Specifically, the buffer layer 21 is in direct contact with the shoe and can be composed of a soft and durable material to provide comfortable sole support and buffering effect. The support layer 22 is an auxiliary shaping part and can be composed of a material with high hardness and good shaping. The support layer 22 is connected to each support module of the module layer 30 to prevent each support module from shaking in the shoe.

[0070] In some embodiments, Figure 4As shown, the surface layer 40 includes a fabric layer 41 and a foam layer 42, the fabric layer 41 is stacked on the upper surface of the foam layer 42, and the lower surface of the foam layer 42 is connected to the module layer 30. Specifically, the fabric layer 41 is located on the upper part of the insole and contacts the foot, which can provide additional comfort and moisture absorption and perspiration functions. The fabric layer 41 can be made of soft and breathable materials, such as fabric or leather. The foam layer 42 can reduce the discomfort of wearing and achieve the effect of gradual correction. It uses foam materials with lower hardness, such as HI-POLY and Ortholite.

[0071] Fig.14 is a three-dimensional diagram of an insole according to another embodiment of the present application, Fig.15 yes Fig.14 An exploded view of the insole is shown, Fig.16 yes Fig.14 3D view of the third support module 33b of the insole shown. Figures 14 to 16 As shown, the height of the outer side of the third support module 33b and the part supporting the palm is higher than the inner side of the third support module 33b, so that the outer side of the third support module 33b and the part supporting the palm form a convex part. Specifically, when correcting flat feet, due to the support of the first support module 31, the foot will tilt outward. At this time, the force on the outer side of the foot will usually increase, and the force on the outer side needs to be dispersed. However, some users also have more force on the center of the forefoot. When the height of the part supporting the palm of the third support module 33b is higher, the force on the palm can be dispersed.

[0072] like Fig.14 and Fig.15 As shown, in some embodiments, the module layer 30 further includes a fifth support module 35 located at the rear end of the calcaneus, and the fifth support module 35 is used to support the heel of the user. Specifically, the fifth support module 35 can disperse the force of the first support module 31 and the second support module 32, so that the force on the user's foot is more balanced.

[0073] In some embodiments, Fig.14 and Fig.15 As shown, the fifth support module 35 has two heel sub-modules arranged opposite to each other on the left and right. Specifically, the two heel sub-modules arranged opposite to each other on the left and right subdivide the heel pressure into left and right sides. The heel sub-modules on the left and right sides can be set according to the heel pressure distribution, which can further balance the walking and standing forces and better achieve the effect of gait correction.

[0074] In some embodiments, the module layer 30 is detachably connected to the surface layer 40 and the base layer 20, respectively, and the surface layer 40 is detachably connected to the base layer 20. Specifically, the module layer 30 and the surface layer 40 and the base layer 20, as well as the surface layer 40 and the base layer 20, can be detachably connected by bonding, sewing, hot-melt connection, etc., so as to quickly make a customized insole for the user.

[0075] In summary, the embodiment of the present application provides an insole, wherein the buffer layer 21, the support layer 22, the module layer 30, the foam layer 42 and the fabric layer 41 are stacked in sequence and can be connected by gluing or other methods. Each support module of the module layer 30 can be produced in advance with different shapes (e.g., different thicknesses, different sizes, etc.) and different materials (e.g., different hardness, different toughness, etc.), and then different modules are selected according to each person's foot shape, plantar pressure distribution, and preferences to be spliced ​​and bonded into a complete insole. The manual bonding time is about 10 minutes per pair, which shortens the customization time compared to traditional printed or engraved insoles.

[0076] Fig.17 FIG. 1 is a three-dimensional diagram of an insole according to another embodiment of the present application. Fig.17 As shown, the embodiment of the present application provides another insole, including a base 60, a receiving surface 61 of the base 60 for receiving a human foot is provided with a first supporting module 31, and the first supporting module 31 is integrally formed with the base 60. Fig.17 The insole for the left foot is shown. When the insole is placed in the user's shoe, the receiving surface 61 of the base 60 contacts the sole of the human body, and the side of the base 60 opposite to the receiving surface 61 is used to contact the sole. The first support module 31 and the base 60 can be integrally formed by 3D printing or engraving, and can be made of EVA, foam or PU material, preferably EVA material. The first support module 31 and the base 60 can be made of appropriate hardness as needed.

[0077] The first support module 31 is located below the inner side of the calcaneus. The first support module 31 is disposed opposite to the talus in the longitudinal direction. The first support module 31 supports the calcaneus and / or the talus upward.

[0078] The first support module 31 can be used to correct flat feet. The first support module 31 is located below the inner side of the calcaneus. Figures 4 to 10 The structure of the first support module 31 in the embodiment shown is similar. Specifically, the upper side of the first support module 31 is convex upward, and the convex part supports the corresponding part of the sole of the foot upward. In this way, the first support module 31 supports the calcaneus upward, which can reduce the medial gap between the calcaneus and the talus, thereby correcting flat feet. Specifically, as Figure 3As shown, when the foot is flat, the calcaneus will turn down to the inside of the calcaneus compared to the normal foot shape. The downward turning of the calcaneus will cause the arch area of ​​the foot to collapse (flat feet) and the heel to turn outward. The first support module 31 supports the calcaneus upward to turn the inside of the calcaneus upward, thereby driving the arch area of ​​the foot upward, improving the collapse of the arch area and the heel to turn outward. In the embodiment of the present application, the inside refers to the side where the big toe of the foot is located, and the outside refers to the side where the little toe of the foot is located.

[0079] like Figure 3 As shown, the supporting points in the figure are Fig.17 The main force bearing point of the first support module 31 on the calcaneus is located at the talar process of the calcaneus, that is, the first support module 31 supports the talar process of the calcaneus upwards.

[0080] In other embodiments, the first support module 31 may also support the talus upward, so that the talus drives the inner side of the calcaneus to turn upward, and also drives the arch area of ​​the foot upward, thereby improving the collapse of the arch area and heel eversion.

[0081] In other embodiments, the first support module 31 may also support the calcaneus and the talus at the same time, so that the supporting force of the first support module 31 can be dispersed, and the discomfort caused to the user by the first support module 31 can be reduced. Specifically, the first support module 31 can support the talar process of the calcaneus and the talus at the same time. For flat feet, the 3D insoles in the prior art only support the arch area, for example, only support the area of ​​the scaphoid and the cuneiform bones, which will cause the scaphoid and the cuneiform bones to flip upward, making the pain more obvious, and the effect of the scaphoid and the cuneiform bones flipping upward to drive the calcaneus to flip upward is not good. The first support module 31 in the embodiment of the present application can support the calcaneus, the talus, or support the calcaneus and the talus at the same time. Compared with the prior art, it can reduce the discomfort caused to the user, and the effect of flipping the calcaneus is better, and the effect of improving flat feet is better.

[0082] In some embodiments, Fig.17 As shown, the upper surface of the first support module 31 protrudes upward, and the highest part of the upper surface of the first support module 31 supports the talar process of the talus and / or the calcaneus. In this way, after the sole of the foot steps on the insole, the highest part of the upper surface of the first support module 31 serves as the main force-bearing part of the support, supporting the talar process of the talus and / or the calcaneus upward, thereby correcting flat feet.

[0083] Specifically, in some embodiments, Fig.17As shown, the upper surface of the first support module 31 is an arc-shaped structure that bulges upward, and the arc-shaped structure is an upward arch, and the height of the first support module 31 gradually decreases from the inner side to the outer side of the foot to fit the calcaneus and talus. The highest part of the upper surface of the first support module 31 is the highest point of the arch. The highest part of the arc-shaped structure can support the talar process of the calcaneus and / or the talus, while the other parts of the arc-shaped structure can also support the scaphoid bone and the cuneiform bone. The first support module 31 only has its highest point at the talar process of the calcaneus and / or the talus.

[0084] In some embodiments, Fig.17 As shown, the receiving surface 61 is further provided with a second support module 32, which is integrally formed with the base 60, and the second support module 32 is located below the outer side of the calcaneus and is arranged opposite to the first support module 31, for supporting the calcaneus. The second support module 32 and the base 60 can be integrally formed by 3D printing or carving.

[0085] The support force of the first support module 31 will cause the foot to have an outward tilting pressure, and the second support module 32 can make the outward tilting pressure return to the inner side of the calcaneus, so that the calcaneus is balanced on the correct force line. The upper surface of the second support module 32 bulges upward and supports the outer side of the calcaneus upward, thereby returning the outward tilting pressure to the inner side of the calcaneus. Specifically, the structure of the second support module 32 in this embodiment is similar to Figures 4 to 10 The structure of the second support module 32 in the illustrated embodiment is similar. The second support module 32 may be an upwardly arched arc structure, and the height of the second support module 32 gradually decreases from the outside to the inside so as to fit the outside of the calcaneus.

[0086] In some embodiments, Fig.17 As shown, the receiving surface 61 is further provided with a third support module 33b, which is used to support at least the outermost metatarsal, and the third support module 33b is integrally formed with the base 60. Specifically, the third support module 33b can support the first metatarsal, the first and second metatarsal, the first to third metatarsal, or the first to fourth metatarsal from the outer side to the inner side of the foot. The third support module 33b is an auxiliary module for the outer side of the palm. After the foot is supported by the first support module 31, the force on the palm position is reduced, and the force on the outer side is increased. The third support module 33b can evenly distribute some of the pressure on the outer side of the metatarsal to the inner side of the metatarsal, thereby maintaining a relative balance of force.

[0087] Among them, the third supporting module 33b in this embodiment is Figures 14 to 16The structure of the third support module 33b of the insole shown is similar, and the height of the outer side of the third support module 33b and the part supporting the palm is higher than the inner side of the third support module 33b, so that the outer side of the third support module 33b and the part supporting the palm form a convex part. Specifically, when correcting flat feet, due to the support of the first support module 31, the foot will tilt outward. At this time, the force on the outer side of the foot will usually increase, and the force on the outer side needs to be dispersed. However, some users also have more force on the center of the forefoot. When the height of the part supporting the palm of the third support module 33b is higher, the force on the palm can be dispersed.

[0088] In some embodiments, the third support module disposed on the base 60 may also be Figures 4 to 10 The structure of the third support module 33a in the illustrated embodiment is similar, and the height of the third support module 33a gradually decreases from the outside to the inside to adapt to the distribution of forefoot pressure gradually decreasing from the outermost metatarsal to the inner metatarsal, so that the forefoot force is more evenly distributed.

[0089] In some embodiments, Fig.17 As shown, the receiving surface 61 is further provided with a fourth support module 34b, which is used to support at least the outermost phalanges, and the fourth support module 34b is integrally formed with the base 60. Specifically, the fourth support module 34b can support the first phalanges, the first and second phalanges, the first to third phalanges, or the first to fourth phalanges from the outer side to the inner side of the foot. After the foot is supported by the first support module 31, the pressure on the outer side of the forefoot increases, and the fourth support module 34b is a forefoot auxiliary module, which is used to distribute some of the pressure on the outer side of the forefoot to the inner side of the forefoot to maintain a relative balance of force.

[0090] The fourth supporting module 34b in this embodiment is Figures 11 to 13 The structure of the fourth support module 34b of the illustrated embodiment is similar, and the height of the fourth support module 34b gradually decreases from the inside to the outside. Specifically, when the user has severe flat feet, it may be accompanied by hallux valgus symptoms. When the height of the fourth support module 34b gradually decreases from the inside to the outside, the inside of the fourth support module 34b is higher, so the big toe can be separated from other fingers, and the force on the big toe area is dispersed, the discomfort of the big toe is relieved, and the correction and customization functions of the hallux valgus and flat foot group can be met.

[0091] In some embodiments, the fourth support module disposed on the base 60 may also be Figures 4 to 10 The structure of the fourth support module 34a in the illustrated embodiment is similar, and the height of the fourth support module 34a gradually decreases from the outside to the inside to adapt to the distribution of the pressure at the forefoot corresponding to the phalanges gradually decreasing from the outermost phalanges to the inner phalanges, so that the forefoot is more evenly stressed.

[0092] In some embodiments, the receiving surface 61 is further provided with a fifth support module located at the rear end of the calcaneus, and the fifth support module is used to support the user's heel, and the fifth support module is integrally formed with the base 60. Specifically, the fifth support module can disperse the force of the first support module 31 and the second support module 32, so that the force on the user's foot is more balanced. Fig.14 and Fig.15 The structure of the fifth support module 35 in the illustrated embodiment is similar, and has two heel sub-modules arranged opposite to each other on the left and right. Specifically, the two heel sub-modules arranged opposite to each other on the left and right subdivide the heel pressure into left and right sides. The heel sub-modules on the left and right sides can be set according to the heel pressure distribution, which can further balance the walking and standing forces and better achieve the effect of gait correction.

[0093] Fig.18 is a three-dimensional diagram of an insole according to another embodiment of the present application. Fig.19 yes Fig.18 An exploded view of the insole is shown. Fig.18 and Fig.19 As shown, this embodiment and Fig.17 Compared with the insole of the illustrated embodiment, the insole further includes a surface layer 70 and a bottom layer 80. The surface layer 70 is attached to the receiving surface 61 of the base 60, and the bottom layer 80 is attached to the side of the base 60 away from the receiving surface 61. The surface layer 70 and the bottom layer 80 can be connected to the base 60 by adhesive bonding or stitching. The surface layer 70 contacts the sole of the user's foot, and the bottom layer 80 contacts the sole of the shoe worn by the user. The surface layer 70 can be made of soft and breathable materials, such as super fiber or bk cloth, etc., which can provide additional comfort and moisture absorption and perspiration functions. The bottom layer 80 can be composed of soft and durable materials, such as foam or EVA, etc., to provide comfortable sole support and cushioning effect.
