[0049] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0050] Embodiment 1

[0051] In order to solve the above problems, the first aspect of the present application provides an insole, as shown in FIG1, including:

[0052] a main body 1 and a forefoot support member 2 connected to the bottom of the main body 1, the forefoot support member 2 being located in the forefoot area of ​​the main body 1;

[0053] the forefoot support member 2 is elastic, so as to deform and store elastic potential energy when compressed, and to provide a thrust toward the forefoot to the main body 1 when releasing the elastic potential energy.

[0054] The second aspect of the present application provides a shoe, including a shoe body and the above-described insole disposed in the shoe body.

[0055] By providing an elastic forefoot support 2 in the forefoot area, the insole can store elastic potential energy when compressed and provide a thrust towards the forefoot when released. This design not only improves the shock absorption effect of the insole but also increases the reaction force during exercise, helping the wearer to push off the ground more effectively, thereby potentially improving speed and stride dynamics.

[0056] Traditional insoles usually focus more on the cushioning performance of the insole, that is, mainly relying on the cushioning performance of the material to reduce impact force, while neglecting the rebound performance of the insole. However, the insole in this embodiment uses the elastic forefoot support 2 to reduce impact force by deforming the forefoot support 2 and release the stored elastic potential energy, thereby providing the wearer with additional thrust support. This makes the insole, while focusing on the cushioning performance of the insole, also have a significant advantage in providing thrust support.

[0057] Specifically, the forefoot support 2 deforms under pressure to reduce impact, and the elastic potential energy stored in the forefoot support 2 after deformation is converted into thrust when the pressure is released, propelling the main body 1 forward. This process not only improves the shock absorption effect of the insole but also increases the reaction force during movement, helping the wearer to push off the ground more effectively, thereby potentially improving speed and stride dynamics.

[0058] It is worth mentioning that the material of the forefoot support 2 can be a material with high resilience, such as ultra-high density PU material with a density greater than 45 kg / m3. This allows the forefoot support 2 to have good resilience after being compressed, which helps the wearer provide thrust support when walking or running. At the same time, the shape and size of the forefoot support 2 can also be adjusted according to different shoe types and usage needs to achieve the best support effect.

[0059] Embodiment Two

[0060] This embodiment is a further improvement based on the first embodiment. The improvement is as follows: as shown in Figures 1 and 3, the forefoot support 2 includes:

[0061] a first support portion 21, corresponding to the part of the forefoot region connected to the big toe region;

[0062] the first projection of the first support portion 21 on the main body 1 overlaps with the big toe region of the main body 1.

[0063] Morphologically, the human foot includes toes, metatarsophalangeal joints, arch, and heel. In this embodiment, the forefoot region is the region on the main body 1 corresponding to the metatarsophalangeal joint, while the big toe region is the region on the main body 1 corresponding to the big toe. When a person runs, during the process of the foot touching the ground, the metatarsophalangeal joint touches the ground first, the body weight presses down further, the leg gradually moves from tilt to vertical, and the force-bearing part of the foot gradually changes from the metatarsophalangeal joint to the metatarsophalangeal joint and the toes. During the subsequent movement, the legs continue to move from vertical to tilted, with the big toe exerting force, and the metatarsophalangeal joint and toes lifting off the ground in turn.

[0064] Therefore, in this embodiment, the first support portion 21 of the forefoot support 2 corresponds to the part of the forefoot region connected to the big toe region, and the first projection of the first support portion 21 on the main body 1 overlaps with the big toe region of the main body 1, so that the first support portion 21 can correspond to the big toe joint and the big toe. In this way, in the initial stage of running, the first support portion 21 can provide support for the big toe joint and the big toe, and reduce the impact force on the big toe joint and the big toe through deformation; while during the process of the foot leaving the ground, as the running action proceeds, the first support portion 21, which is deformed due to pressure, gradually releases the stored elastic potential energy to provide thrust support for the big toe joint and the big toe in turn, which helps the wearer to push off the ground more effectively, thereby potentially improving speed and stride dynamics.

[0065] In some preferred embodiments, the first projection covers the toe pad of the big toe region.

[0066] It is worth mentioning that during the process of the foot exerting force to leave the ground, the force is mainly generated by the big toe, and the toe pad of the big toe is the main part in contact with the insole. Therefore, the pad of the big toe plays a crucial role in both the foot's contact with and lift-off. Setting the first projection to cover the pad of the big toe area provides effective support for the big toe, offering effective cushioning during foot contact and providing thrust support during foot lift-off, thereby improving the overall athletic experience.

[0067] To further enhance the support for the big toe, in some preferred embodiments, the first projection completely covers the big toe area. This arrangement increases the area of ​​the first support portion 21 in the big toe area, thereby improving the support for the big toe and providing better thrust support.

[0068] Embodiment Three

[0069] This embodiment is a further improvement based on the second embodiment. The improvement is that, as shown in Figures 1 and 3, the forefoot support member 2 further includes:

[0070] a second support portion 22, connected to the first support portion 21, and corresponding to the portion where the forefoot region connects to the other four toe regions;

[0071] the shape of the second support portion 22 is adapted to the shape of the forefoot region.

[0072] In this embodiment, the forefoot support member 2 includes a first support portion 21 and a second support portion 22. The first support portion 21 is connected to the big toe region, and the second support portion 22 is connected to the first support portion 21, and corresponds to the portion where the forefoot region connects to the other four toe regions. As can be seen from the above, the forefoot region is the region on the main body 1 corresponding to the metatarsophalangeal joint, and the first support portion 21 can correspond to the big toe joint and the big toe. Similarly, the second support portion 22 can correspond to the other four toe joints except the big toe joint, and is used to support the other four toe joints.In this way, in the initial stage of running, the second support 22 can provide support for the other four toe joints and reduce the impact force on the other four toe joints through deformation; while during the process of the foot leaving the ground, as the running action proceeds, the second support 22, which deforms due to pressure, gradually releases the stored elastic potential energy to provide thrust support for the other four toe joints, which helps the wearer to push off the ground more effectively, thereby potentially improving speed and stride dynamics.

[0073] It is worth mentioning that, as shown in Figure 3, based on the study of foot pressure during human movement, in the wearer's walking cycle, when the wearer starts, the plantar pressure of the foot gradually moves from the outer side of the forefoot along the direction of the arrow in Figure 3 to the big toe. Therefore, through the setting of the first support 21 and the second support 22, the shape of the forefoot support 2 matches the pressure area of ​​the sole of the foot, so that the shape of the forefoot support 2 can match the trend of the plantar pressure, thereby providing effective push for the foot.

[0074] In some preferred embodiments, the width of the connection between the first support portion 21 and the second support portion 22 gradually decreases from the direction of the first support portion 21 toward the direction of the second support portion 22, and the minimum width of the connection portion is greater than the maximum width of the second support portion 22. This arrangement increases the area of ​​the connection between the first support member and the second support member, allowing for a smooth transition between the connection and the second support frame. This ensures the stability of the connection between the first and second support members, preventing tearing of the connection between the first support member and the second support frame after prolonged use or strenuous exercise, effectively improving the durability of the insole. Furthermore, this arrangement makes the shape of the forefoot support member 2 more closely match the shape of the pressure area on the sole of the foot, effectively reducing material usage and thus lowering production costs.

[0075] In some preferred embodiments, the angle between the line connecting the end of the first support 21 near the heel region of the main body 1 and the end of the second support 22 near the heel region of the main body 1 and the length extension direction of the main body 1 is 70°-80°;

[0076] The connecting line extends along the inner side of the main body 1 toward the outer side of the main body 1 and is inclined toward the heel direction of the main body 1. This design makes the shape of the forefoot support 2 more consistent with the shape of the pressure area of ​​the sole of the foot, and the insole can better adapt to the shape and movement of the foot during use, thereby improving the shock absorption effect of the insole and increasing the reaction force during exercise, which helps the wearer to push off the ground more effectively, thereby potentially improving speed and stride dynamics.

[0077] Embodiment Four

[0078] This embodiment is a further improvement based on the second or third embodiment. The improvement is that, as shown in Figures 1, 2, and 3, the insole further includes:

[0079] an arch support 3, connected to the bottom of the main body 1 and corresponding to the arch area of ​​the main body 1;

[0080] the arch support 3 is elastic, deforming and storing elastic potential energy under pressure, and providing a thrust towards the arch to the main body 1 when releasing the elastic potential energy.

[0081] By providing the arch support 3, the deformation of the arch support 3 is used to mitigate impact and release the stored elastic potential energy, thereby providing additional thrust support for the wearer. The elastic deformation and potential energy release mechanism of the arch support 3 ensures effective support and cushioning performance for the arch area under pressure, and provides additional thrust when releasing pressure, improving the comfort and support effect of the insole, and potentially increasing the wearer's movement speed and stride dynamics.

[0082] It is worth mentioning that the material of the arch support 3 can be a material with high resilience and high flexibility, such as DuPont PA12 material, which combines extensibility and rigidity, helping to provide thrust support when the wearer walks or runs.

[0083] In some preferred embodiments, the arch support 3 includes:

[0084] a third support portion 31, which corresponds to the outer longitudinal arch region of the arch area;

[0085] the third support portion 31 arches towards the arch so that the bottom of the third support portion 31 is suspended.

[0086] The third support portion 31, corresponding to the outer longitudinal arch region of the arch area, can provide targeted support. Moreover,

[0087] the third support portion 31 arches towards the arch so that the bottom of the third support portion 31 is suspended, which provides effective cushioning and support in the arch area. The arched third support 31, with its suspended structure, provides space for the deformation and sinking of the third support 31, thereby increasing the deformation range of the third support 31, improving the cushioning capacity of the third support 31 and the elastic potential energy it can store, thus providing effective thrust support for the foot, and potentially improving the wearer's movement speed and stride dynamics.

[0088] Specifically, during the process of the foot touching the ground, the body weight further presses down, and the leg gradually moves from tilt to vertical. The third support 31 will press down along with the arch of the foot, and reduce the impact force on the arch of the foot and store deformation potential energy through deformation. During the process of the foot leaving the ground, when the leg gradually moves from vertical to tilt, the third support 31 can release the stored deformation potential energy, push the arch area of ​​the insole upward, provide push assistance for the foot leaving the ground, save the wearer's physical strength, and potentially improve the wearer's movement speed and stride dynamics.

[0089] In some preferred embodiments, as shown in FIG2, the arch support 3 further includes:

[0090] a fourth support portion 32, which is connected to the third support portion 31 and corresponds to the inner longitudinal arch region of the arch area.

[0091] Specifically, in this embodiment, the arch support 3 includes a third support portion 31 and a fourth support portion 32 connected to each other. The third support portion 31 corresponds to the outer longitudinal arch region of the arch area, and the fourth support portion 32 corresponds to the inner longitudinal arch region of the arch area. Both support the outer and inner longitudinal arch regions of the wearer, respectively. On the one hand, they can provide effective cushioning, and on the other hand, they can provide thrust support for the arch during the process of the foot leaving the ground, thereby improving the overall sports experience.

[0092] In this embodiment, as shown in FIG2, on the cross-section of the arch perpendicular to the length direction of the main body 1, the angle between the fourth support portion 32 and the third support portion 31 is 15°-25°. The angle design allows the force applied to the arch of the foot to be more even, rather than concentrated on a single point, which helps to provide a more stable and even support effect in the arch area, avoiding the shortcomings of traditional insoles in terms of arch support. In some specific embodiments, the angle between the fourth support part 32 and the third support part 31 can be set to 20°.

[0093] In addition, the third support part 31 and the fourth support part 32 can support the arch of the foot (medial longitudinal arch, lateral longitudinal arch and transverse arch), so that the insole can provide full arch support when running, which is suitable for various foot types. In addition, if the wearer has flat feet, the arch support 3 can effectively improve the excessive downward pressure on the arch caused by flat feet; if the wearer has a normal arch or a high arch, the arch support 3 can also increase the contact area of ​​the sole, evenly distribute the pressure on the sole, and improve comfort.

[0094] Embodiment Five

[0095] This embodiment is an improvement based on Embodiment Four. The improvement is that, as shown in Figure 1, the insole further includes:

[0096] a heel support 4, which corresponds to the heel area of ​​the main body 1 and is used to support the heel.

[0097] During walking or running, the heel of the foot usually needs to withstand the impact force when the foot touches the ground. Therefore, by setting up the heel support 4, the impact force is absorbed and buffered, reducing the reaction force from the bottom surface on the foot.

[0098] In some embodiments, the heel support 4 has a hollow structure, which can deform by compressing the internal hollow space when under pressure. By setting up this hollow structure, the characteristic of the hollow structure being deformable when under pressure is utilized to absorb and buffer the impact force.Moreover, the hollow structure has hollowed-out spaces inside, which can be deformed by compressing the hollowed-out spaces inside the hollow structure, so that the hollow structure can obtain a large deformation when under pressure, thereby improving the cushioning capacity of the heel support 4. Specifically, the hollow structure can be a strip-shaped groove set at the bottom of the heel support 4, or it can be multiple cavities set inside the heel support 4. It is worth mentioning that the material of the heel support 4 can be PU gel to obtain better shock absorption performance.

[0099] In some preferred embodiments, as shown in Figures 1, 2 and 3, the insole further includes:

[0100] an intermediate support 5, which is set between the main body 1 and the arch support 3, and corresponds to the arch area of ​​the main body 1; Specification 6 / 7 pages 9 CN 122070837 A

[0101] The second projection of the intermediate support 5 on the main body 1 at least covers the arch area of ​​the main body 1.

[0102] By providing an intermediate support 5 between the main body 1 and the arch support 3, it can cooperate with the arch support 3 to provide multi-stage cushioning, further enhancing the support and cushioning performance of the arch area, and helping to improve the stability and controllability of the wearer during exercise. In some embodiments, the intermediate support 5 can be made of high-density PU material with a density of 25-45 kg / m3. It is worth mentioning that the intermediate support 5 and the arch support 3 are made of different materials, and their respective cushioning performance and rebound force are different. Therefore, when the insole is compressed, it can provide multi-stage cushioning for the arch, so that the impact force borne by the arch can be cushioned in stages, the cushioning process is smooth and the cushioning effect is good.

[0103] In some preferred embodiments, an intermediate support 5 can also be provided between the main body 1 and the heel support 4 to further enhance the support and cushioning performance of the heel area. Specifically, in some embodiments, the intermediate support 5 can extend from the arch region to the heel region, that is, the intermediate support 5 as a whole covers both the arch region and the heel region; while in other embodiments, intermediate support 5 can be respectively provided at the corresponding positions of the heel region and the arch region, and the two intermediate support 5 can be made of different materials to meet the respective cushioning performance requirements of the heel region and the arch region.

[0104] In some preferred embodiments, as shown in FIG3, the second projection is staggered with the forefoot region of the main body 1, and there is a gap between the second projection and the forefoot region, the gap being greater than or equal to 3mm.

[0105] According to the study of human gait, the toe joints need to bend during walking or running. Therefore, through this design, there is a gap between the intermediate support 5 and the forefoot support 2 to meet the bending requirements of the toe joints during walking or running, and to avoid the intermediate support 5 affecting the bending of the toe joints.

[0106] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.

The insole comprises: a main body and a forefoot support member connected to a bottom of the main body, wherein the forefoot support member is correspondingly located in a forefoot region of the main body; the forefoot support member has elasticity so as to deform and store elastic potential energy when subjected to pressure, and to provide a thrust toward the forefoot to the main body when releasing the elastic potential energy. By virtue of the elastic forefoot support member, the insole utilizes deformation to reduce impact force and releases the stored elastic potential energy, thereby providing additional thrust support for the wearer, so that the insole has significant advantages in providing propulsion support while also focusing on cushioning performance.
