Description

Technical Field

[0001] This application relates to the field of footwear accessories technology, and more specifically, to a supportive insole and a shoe. Background Technology

[0002] Current insole technology typically employs material shock absorption to reduce pressure during exercise. Additionally, by shaping the insole to resemble the foot's form, the contact area is increased, thus distributing pressure more evenly. However, this design approach has some limitations. First, relying solely on material shock absorption may not effectively handle impacts of varying intensities, resulting in less than ideal pressure reduction. Second, while increasing the contact area can disperse pressure to some extent, it remains insufficiently precise and effective for providing support and protection to specific areas. Utility Model Content

[0004] The main body and a forefoot support member connected to the bottom of the main body, the forefoot support member being located in the forefoot area of ​​the main body;

[0005] The forefoot support is elastic to deform and store elastic potential energy when compressed, and to provide a thrust toward the forefoot to the body when the elastic potential energy is released.

[0015] A further technical solution may be that the angle between the line connecting the end of the first support portion near the heel region of the main body and the end of the second support portion near the heel region of the main body and the length extension direction of the main body is 70°-80°.

[0016] The connecting line extends along the inside of the body toward the outside of the body and slopes toward the heel of the body.

[0017] A further technical solution could be that the insole also includes:

[0018] An arch support is attached to the bottom of the main body and corresponds to the arch area of ​​the main body;

[0019] The arch support is elastic to deform and store elastic potential energy when compressed, and to provide a thrust toward the arch to the body when the elastic potential energy is released.

[0020] A further technical solution could be that the arch support component includes:

[0021] The third support portion corresponds to the outer longitudinal arch region of the foot arch region;

[0022] The third support arches towards the arch of the foot so that the bottom of the third support is suspended in the air.

[0023] A further technical solution could be that the arch support also includes:

[0024] The fourth support part is connected to the third support part and corresponds to the inner longitudinal arch region of the foot arch region;

[0025] On the cross-section of the arch of the foot perpendicular to the length direction of the main body, the angle between the fourth support and the third support is 15°-25°.

[0026] A further technical solution could be that the insole also includes:

[0027] A heel support member, which corresponds to the heel area of ​​the main body, is used to support the heel;

[0028] The heel support has a hollow structure, which can deform by compressing the internal hollow space when under pressure.

[0029] The insole also includes:

[0030] An intermediate support member is disposed between the main body and the arch support member, and corresponds to the arch area of ​​the main body;

[0031] The second projection of the intermediate support onto the main body at least covers the arch region of the main body.

[0032] A further technical solution could be that the second projection is staggered from the forefoot area of ​​the main body, and there is a gap between the second projection and the forefoot area, the gap being greater than or equal to 3mm.

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

[0050] Implementation Method 1

[0051] To address the aforementioned problems, a first aspect of this application provides an insole, such as... Figure 1 As shown, it includes:

[0052] The main body 1 and the forefoot support 2 connected to the bottom of the main body 1, wherein the forefoot support 2 is located in the forefoot area of ​​the main body 1;

[0053] The forefoot support 2 is elastic, so that it deforms and stores elastic potential energy when compressed, and provides a thrust toward the forefoot to the body 1 when the elastic potential energy is released.

[0054] The second aspect of this embodiment provides a shoe, including a shoe body and an insole disposed within the shoe body as described above.

[0055] By incorporating a resilient forefoot support 2 in the forefoot area, the insole can store elastic potential energy when compressed and provide a thrust toward the forefoot when released. This design not only improves the insole's shock absorption but also increases the reaction force during movement, helping the wearer to push off the ground more effectively, potentially improving speed and stride dynamics.

[0056] Traditional insoles typically focus on cushioning performance, relying primarily on the material's cushioning properties to mitigate impact, while neglecting the insole's rebound performance. However, the insole in this embodiment utilizes an elastic forefoot support 2. The deformation of this forefoot support 2 reduces impact and releases stored elastic potential energy, thereby providing the wearer with additional thrust support. This insole, while emphasizing cushioning performance, also offers significant advantages in providing thrust support.

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

[0058] It's worth mentioning that the forefoot support component 2 can be made of a material with high resilience, such as ultra-high density PU material with a density greater than 45 kg / m³. 3 This allows the forefoot support component 2 to have excellent resilience after being compressed, which helps support the wearer's thrust when walking or running. At the same time, the shape and size of the forefoot support component 2 can also be adjusted according to different shoe types and usage needs to achieve the best support effect.

[0059] Implementation Method 2

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

[0061] The first support portion 21 corresponds to the part of the forefoot region that connects to the big toe region;

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

[0063] Morphologically, the human foot includes the toes, metatarsophalangeal joints, arch, and heel. In this embodiment, the forefoot area corresponds to the metatarsophalangeal joint on the main body 1, while the big toe area corresponds to the big toe on the main body 1. When a person runs, during the foot's initial contact with the ground, the metatarsophalangeal joints touch the ground first, the body weight further presses down, and the leg gradually moves from an angle to a vertical position. The force-bearing points of the foot gradually shift from the metatarsophalangeal joints to the metatarsophalangeal joints and toes. In subsequent movements, the leg continues to gradually move from a vertical position to an angle, the big toe exerts force, and the metatarsophalangeal joints and toes lift off the ground in sequence.

[0064] Therefore, in this embodiment, the first support portion 21 of the forefoot support 2 corresponds to the part of the forefoot region that connects to the big toe region. 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. 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 pad of the big toe region.

[0066] It's worth noting that during the foot's power lift off the ground, the big toe is the primary source of force, and the 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 foot contact and liftoff. 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 liftoff, thereby improving the overall athletic experience.

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

[0068] Implementation Method 3

[0069] This embodiment is a further improvement based on the second embodiment, and the improvement is as follows: Figure 1 and Figure 3 As shown, the forefoot support 2 also includes:

[0070] The second support portion 22 is connected to the first support portion 21 and corresponds to the part where the forefoot area connects to the other four toe areas;

[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 2 includes a first support portion 21 and a second support portion 22. The first support portion 21 is connected to the big toe area, and the second support portion 22 is connected to the first support portion 21, corresponding to the part where the forefoot area connects to the other four toe areas. As can be seen, the forefoot area is the area 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 itself. Similarly, the second support portion 22 can correspond to the other four toe joints (excluding the big toe joint) to support them. Thus, in the initial stage of running, the second support portion 22 can provide support for the other four toe joints and reduce the impact force on them through deformation. During the foot leaving the ground, as the running motion progresses, the second support portion 22, deformed by pressure, gradually releases its stored elastic potential energy to provide thrust support for the other four toe joints, helping the wearer to push off the ground more effectively, potentially improving speed and stride dynamics.

[0073] It is worth mentioning that, for example Figure 3 As shown, based on research on foot pressure during human movement, during the wearer's walking cycle, at the moment the wearer begins to move, the plantar pressure of the foot moves from the outer forefoot along... Figure 3 The direction of the middle arrow gradually moves towards the big toe. Therefore, through the arrangement of the first support part 21 and the second support part 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 conform to the trend of the sole pressure, thereby providing effective support 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 towards 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 and second support members, allowing for a smooth transition between them. This ensures the stability of the connection between the first and second support members, preventing tearing of the connection after prolonged use or strenuous exercise, and 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 portion 21 near the heel region of the main body 1 and the end of the second support portion 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 towards the outer side of the main body 1 and slopes towards the heel of the main body 1. This design makes the shape of the forefoot support 2 more closely match the shape of the pressure area on the sole of the foot. During use, the insole can better adapt to the shape and movement of the foot, thereby improving the shock absorption effect of the insole and increasing the reaction force during exercise. This helps the wearer to push off the ground more effectively, potentially improving speed and stride dynamics.

[0077] Implementation Method 4

[0078] This embodiment is a further improvement based on the second or third embodiment, and the improvement is that, for example... Figure 1 , Figure 2 and Figure 3 As shown, the insole also includes:

[0079] An arch support 3 is connected to the bottom of the main body 1 and corresponds to the arch area of ​​the main body 1;

[0080] The arch support 3 is elastic to deform and store elastic potential energy when compressed, and to provide a thrust toward the arch to the body 1 when the elastic potential energy is released.

[0081] By incorporating an arch support component 3, the deformation of the arch support component 3 mitigates impact and releases stored elastic potential energy, thereby providing the wearer with additional thrust support. The elastic deformation and potential energy release mechanism of the arch support component 3 ensures effective support and cushioning in the arch area under pressure, and provides additional thrust when releasing pressure, enhancing the insole's comfort and support, and potentially improving the wearer's movement speed and stride dynamics.

[0082] It is worth mentioning that the material selection for the arch support component 3 can be a material with high resilience and high flexibility, such as DuPont PA12 material, which combines extensibility and rigidity, and helps the wearer with thrust support when walking or running.

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

[0084] The third support portion 31 corresponds to the outer longitudinal arch region of the foot arch region;

[0085] The third support 31 arches towards the direction of the arch of the foot so that the bottom of the third support 31 is suspended in the air.

[0086] The third support section 31 corresponds to the lateral longitudinal arch region of the foot arch area, providing targeted support. Furthermore,

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

[0088] Specifically, during the foot's contact with the ground, the body weight presses down further, and the leg gradually moves from an inclined position to a vertical position. The third support part 31 presses down along with the arch of the foot and reduces the impact force on the arch of the foot and stores deformation potential energy through deformation. During the foot's lift-off, when the leg gradually moves from a vertical position to an inclined position, the third support part 31 can release the stored deformation potential energy, causing the arch area of ​​the insole to push upward, providing a push assist for the foot to lift off the ground, saving the wearer's physical strength, and potentially increasing the wearer's movement speed and stride dynamics.

[0089] In some preferred embodiments, such as Figure 2 As shown, the arch support 3 also includes:

[0090] The fourth support part 32 is connected to the third support part 31 and corresponds to the inner longitudinal arch region of the foot arch region.

[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 lateral longitudinal arch region of the arch area, and the fourth support portion 32 corresponds to the medial longitudinal arch region of the arch area. Both support the lateral and medial longitudinal arch regions of the wearer, respectively. On the one hand, this provides effective cushioning, and on the other hand, it provides thrust support for the arch during the foot's departure from the ground, thereby improving the overall sports experience.

[0092] In this embodiment, as Figure 2 As shown, in the cross-section of the arch of the foot perpendicular to the length of the main body 1, the angle between the fourth support portion 32 and the third support portion 31 is 15°-25°. This angle design allows the force applied to the arch of the foot to be more even, preventing it from concentrating at a single point. This 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 portion 32 and the third support portion 31 can be set to 20°.

[0093] Furthermore, the third support part 31 and the fourth support part 32 support the arch of the foot (medial longitudinal arch, lateral longitudinal arch, and transverse arch), providing full arch support during running and suitable for various foot types. Additionally, if the wearer has flat feet, the arch support 3 effectively reduces excessive arch compression caused by flat feet; if the wearer has normal or high arches, the arch support 3 also increases the contact area with the sole, evenly distributing pressure and improving comfort.

[0094] Implementation Method 5

[0095] This implementation method is an improvement based on implementation method four, and the improvement is as follows: Figure 1 As shown, the insole also includes:

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

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

[0098] In some embodiments, the heel support 4 has a hollow structure, which deforms by compressing its internal hollow spaces when under pressure. This hollow structure absorbs and buffers impact forces by utilizing its deformable characteristic under pressure. Furthermore, the hollow space within the structure allows for deformation by compressing these spaces, enabling the hollow structure to achieve a larger deformation under pressure, thereby improving the cushioning capacity of the heel support 4. Specifically, the hollow structure can be a strip-shaped groove at the bottom of the heel support 4, or multiple cavities within the heel support 4. It is worth noting that the heel support 4 can be made of PU gel to achieve better shock absorption performance.

[0099] In some preferred embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the insole also includes:

[0100] The intermediate support 5 is disposed between the main body 1 and the arch support 3, and corresponds to the arch area of ​​the main body 1;

[0101] The second projection of the intermediate support 5 onto the main body 1 at least covers the arch region of the main body 1.

[0102] By providing an intermediate support member 5 between the main body 1 and the arch support member 3, it can cooperate with the arch support member 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 member 5 can be made of high-density PU material with a density of 25-45 kg / m³. 3 It is worth mentioning that the intermediate support component 5 and the arch support component 3 are made of different materials, and their 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, resulting in a smooth cushioning process and good cushioning effect.

[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 area to the heel area, that is, the intermediate support 5 as a whole covers both the arch area and the heel area; while in other embodiments, intermediate support 5 can be provided at corresponding positions in the heel area and the arch area, and the two intermediate support 5 can be made of different materials to meet the respective cushioning performance requirements of the heel area and the arch area.

[0104] In some preferred embodiments, such as Figure 3 As shown, the second projection is offset from the forefoot area of ​​the main body 1, and there is a gap between the second projection and the forefoot area, the gap being greater than or equal to 3mm.

[0105] Studies on human gait show that the toe joints need to flex during walking or running. Therefore, this design creates a gap between the intermediate support 5 and the forefoot support 2 to meet the flexion requirements of the toe joints during walking or running, and to prevent the intermediate support 5 from affecting the flexion 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 illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
