Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a shoe sole and shoe with dynamic arch support. Background Technology

[0002] The healthy development of children's feet is crucial for their posture, motor skills, and long-term skeletal health. The arch of the foot, as a vital structure, bears the burden of cushioning impacts, supporting weight, maintaining balance, and assisting in walking, running, and jumping. However, because children's skeletal and ligament systems are not yet fully developed, their arch structures are relatively weak. Furthermore, some children have congenital flat feet or acquired developmental problems, making their arches prone to fatigue, collapse, and even pain during daily activities and exercise. Current technology typically uses raised insoles to support the arch, but this method deforms due to long-term compression of the insole material, causing the support effect to diminish over time. Moreover, children's movement patterns are complex and varied; they require good comfort during normal walking and good support during high-speed movement. The support effect of ordinary raised insoles cannot adjust according to the child's movement patterns, and the overall arch support cannot meet the needs. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a shoe sole and shoe with dynamic arch support, the support effect of which can be appropriately adjusted according to the child's movement state to provide better arch support performance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A dynamic arch support sole, comprising: an upper midsole; and an arch support block, which is composited below the upper midsole and corresponds to the arch area, the arch support block being made of a shear-thickened material and having a higher hardness than the upper midsole when not under stress; the inner and outer sidewalls of the arch support block extend upwards in an arched shape in the front-back direction to form a sidewall higher than the middle part of the arch support block in the left-right direction, and a support area adapted to the shape of the arch area is defined on the upper surface of the arch support block; the outer sidewall is recessed towards the inner sidewall and has a hollow groove extending in the front-back direction, the hollow groove having a plurality of support arms extending in the left-right direction and arranged in the front-back direction, the support arms dividing the hollow groove into a plurality of hollow holes arranged in the front-back direction and not interconnected; the inner sidewall protrudes and has a plurality of first reinforcing ribs extending in the vertical direction to connect the upper and lower edges of the inner sidewall and arranged in the front-back direction.

[0006] Technical Solution 2 based on Technical Solution 1: The outer wall forms a first groove wall on the lower side and a second groove wall on the upper side through the hollow groove. The first groove wall extends perpendicular to the vertical direction. The second groove wall includes a first wall surface extending perpendicular to the vertical direction and a second wall surface that connects to the first wall surface and extends from bottom to top. The second wall surface is located outside the first wall surface relative to the bottom of the hollow groove, and the support arm extends on the second wall surface to form a second reinforcing rib on the outer wall.

[0007] Technical Solution 3 based on Technical Solution 2: The second reinforcing rib extends upward to the upper edge of the outer side wall.

[0008] Technical Solution 4 based on Technical Solution 3: The first reinforcing rib and the second reinforcing rib extend obliquely forward and backward in relative vertical directions before and after the highest point of the upper edge of the inner wall and the outer wall, respectively.

[0009] Technical Solution 5 based on Technical Solution 3: The arch support block is integrally formed by an inner support part near the inside and an outer support part near the outside in the left-right direction; the front edge and rear edge of the arch support block are respectively curved and protruding towards the rear and front, and the line connecting the two closest positions in the front-back direction constitutes the dividing line between the inner support part and the outer support part; the dividing line between the inner support part and the outer support part is closer to the outer wall in the left-right direction.

[0010] Technical solution six based on technical solution five: The bottom of the hollowed-out groove does not exceed the boundary line between the inner support part and the outer support part in the left and right direction.

[0011] Technical solution seven based on technical solution five: the upper surface of the arch support block is provided with a plurality of first fitting parts in the portion of the inner support part; the lower surface of the upper midsole is provided with a plurality of second fitting parts; the first fitting parts and the second fitting parts are adapted to fit together when the arch support block is combined with the upper midsole.

[0012] Technical solution eight based on technical solution three: On the projection plane perpendicular to the left and right direction, the projection shape of the outer side wall is located within the projection shape of the inner side wall in the front and back direction.

[0013] Technical solution nine based on technical solution eight: On the projection plane perpendicular to the left and right direction, the upper edge of the projection shape of the inner sidewall is higher than the upper edge of the projection shape of the outer sidewall.

[0014] In addition, this utility model also provides technical solution ten: a shoe with dynamic arch support, which includes an upper and a sole with dynamic arch support as described in any one of technical solutions one to nine, wherein the upper is composite to the sole.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] Technical Solution 1 provides a dynamic arch support sole, which addresses the core problem that existing arch support devices cannot simultaneously satisfy both comfort during low-intensity exercise and protection during high-intensity exercise. This solution achieves adaptive changes in the mechanical properties of the arch support in the sole through the synergistic effect of materials and structure.

[0017] First, the sole of this invention consists of a functionally separated upper midsole and an arch support block. The arch support block uses a shear-thickened material, and its stiffness when unloaded is higher than that of the upper midsole. Because the arch support block is stiffer than the upper midsole and is located below the upper midsole corresponding to the user's arch, it effectively resists deformation of the sole under stress. When the user is standing, the arch support block, relying on its inherent high modulus, provides a stable support platform for the arch, preventing it from collapsing under weight. When the user engages in high-intensity activities such as running and jumping, the ground impact force is a high-strain-rate load. The physical properties of the shear-thickened material determine that its internal molecular network will momentarily lock under high strain rates, resulting in a sharp increase in the material's viscoelastic modulus. This means that the overall stiffness of the arch support block will significantly increase at the moment of impact, providing higher support than in a static state to withstand greater impact loads. Therefore, the support performance of the sole can adaptively adjust according to changes in external load.

[0018] Secondly, the structural design of the arch support block effectively translates the aforementioned material properties into functionality. Its inner and outer walls extend upwards, forming a sidewall structure that physically applies lateral restraint to the foot, limiting excessive displacement in the left-right direction and improving stability during movement. The first reinforcing rib on the inner wall essentially increases the second moment of the cross-section in that area, enhancing the inner wall's resistance to bending deformation, thus more effectively supporting the medial longitudinal arch and preventing it from collapsing under high loads.

[0019] Crucially, the perforated grooves, support arms, and perforated holes on the outer wall address the issues of insufficient flexibility and lack of gait guidance that can result from using rigid dynamic materials. If both the inner and outer sides used equally robust reinforced structures, the entire support block would be too rigid, hindering the necessary and natural deformation of the foot upon landing and failing to intervene in poor gait. This invention's perforated structure, by removing material, actively reduces the overall structural stiffness of the outer wall, making it lower than the rigid inner wall. This resolves the contradiction between rigidity and flexibility. When the foot tends to roll inward, this relatively flexible outer structure can undergo greater controllable compressive deformation than the inner structure, generating a corrective torque to counteract excessive pronation. Simultaneously, the support arms in the perforated grooves connect and transfer loads, preventing the outer wall from failing due to excessive perforation and ensuring that it provides both flexibility and necessary support.

[0020] Therefore, the dynamic arch support sole provided by this solution, through the deep coupling of materials and structure, enables the sole to provide adaptive support and stability functions that cannot be achieved by existing technologies, providing good comfort during normal wear and excellent support performance during high-speed exercise.

[0021] In technical solution two, the outer wall is deconstructed into a lower first groove wall and an upper second groove wall, and the curved shape of the second groove wall is defined, making the force transmission path clearer and more controllable when the outer wall is deformed under pressure. Furthermore, the support arm includes a second reinforcing rib extending from the second wall surface, giving the support arm, which originally only served a connecting and supporting function, the function of constituting a reinforcing structure. This allows the outer wall to achieve hollowing out for weight reduction and increased flexibility while also possessing good structural strength and durability.

[0022] In technical solution three, the second reinforcing rib is extended upward to the upper edge of the outer side wall, which improves the structural strength of the upper edge of the outer side wall, makes the stress distribution of the entire side wall more uniform, avoids local stress concentration, and effectively improves the overall structural strength and fatigue resistance of the arch support block.

[0023] In technical solution four, the first and second reinforcing ribs are designed as arched profiles that extend backward and forward at the highest point. The arched structure can more effectively decompose the vertical load into pressure along the axial direction of the component, so that the reinforcing ribs can transmit and disperse the downward pressure from the arch of the foot in the most efficient way, thereby providing a stronger support effect with the same amount of material.

[0024] In technical solution five, the arch support block forms an "X" shape through the curved structure of the front and rear edges. This ensures that the sole has sufficient deformation capacity in the arch area without affecting the support effect of the arch support block on the user's foot arch.

[0025] In technical solution six, the bottom of the hollow groove is limited to the boundary line between the inner and outer support parts, ensuring that the inner support part, as the main support area, has a complete structure and the highest rigidity, so that it can fully undertake the task of supporting the inner longitudinal arch. At the same time, the function of providing flexible deformation is strictly controlled in the outer support part, ensuring the realization of the support effect of the entire arch support block.

[0026] In technical solution seven, a first fitting part is provided in the inner support section, and a corresponding second fitting part is provided in the upper midsole. The two parts can fit together to form a mechanical interlock. This interlocking structure can effectively resist the shear force generated during movement and prevent the two parts from sliding relative to each other. This ensures that the arch support block is always in the correct position, thereby ensuring the stability of the arch support function.

[0027] In technical solution eight, the length of the projection shape of the outer side wall in the front-back direction is designed to be within the projection shape of the inner side wall, that is, the outer side wall is shorter than the inner side wall. This makes the coverage of the arch support block more closely fit the core support area of ​​the sole of the foot, avoiding excessive restriction on unnecessary areas of the outer side of the foot, thereby improving wearing comfort and movement flexibility.

[0028] In technical solution nine, the upper edge of the projected shape of the medial sidewall is designed to be higher than that of the lateral sidewall. The higher medial sidewall provides a larger resistance arm when the foot tends to roll inward, thus generating a more effective corrective torque. This asymmetrical height design greatly enhances the sole's ability to resist excessive pronation.

[0029] Technical solution ten provides a shoe with dynamic arch support, which can provide comprehensive, stable and comfortable arch support for wearers, especially children whose arches are still developing or who have functional arch problems. Attached Figure Description

[0047] Example 1

[0048] This utility model relates to a shoe sole with dynamic arch support, as shown in the following embodiment. Figure 1 and Figure 2 The sole includes an upper midsole 100 and an arch support block 200. Preferably, an outsole can be composited below the upper midsole 100 and the arch support block 200, and the outsole can be made of TPU, rubber, or nylon, etc.

[0049] upper layer, middle layer, 100 structure reference Figure 1 , Figure 2 as well as Figure 7 and Figure 8 The diagram illustrates both the composite structure of the upper midsole 100 and the arch support block 200, and the structure of the upper midsole 100 alone. This upper midsole 100 can be made of EVA material or other conventional midsole materials, and its configuration resembles a conventional sole shape. (See also...) Figure 7 and Figure 8A concave composite groove 110 is formed on the bottom surface of the upper midsole 100 at the position corresponding to the arch of the foot. The shape of the composite groove 110 is adapted to the shape of the arch support block 200. The arch support block 200 can be embedded and fixed into the composite groove 110 by adhesive bonding to form a stable connection with the upper midsole 100.

[0050] The arch support block 200 of the shoe sole is composited below the upper midsole 100 and corresponds to the arch area. It is made of shear-thickened material, and its hardness is higher than that of the upper midsole 100 when not under stress. Specifically, the arch support block 200 is made of shear-thickened material, which is a smart material with special mechanical response characteristics. Its physical state changes significantly with the shear force (such as compression, friction, impact, etc.): when subjected to small external forces or no force, the particles or molecules inside the material are in a relatively loose and free state, exhibiting low hardness and easy deformation characteristics similar to gels or elastomers; however, when subjected to a sudden increase in shear force (such as when the arch area is subjected to rapid pressure or torsional force during exercise), the particles inside the material will quickly aggregate to form a rigid structure, the molecular chains will be instantly "locked," and the hardness and impact resistance will be drastically increased, thereby producing a strong support and cushioning effect. In this embodiment, the shear thickening material is a polyborosiloxane shear thickening adhesive. Since the hardness of the shear thickening material needs to be higher than that of the upper midsole 100 when not under stress, if a specific brand of polyborosiloxane shear thickening adhesive cannot meet this requirement, rigid fillers or crosslinking agents can be added for modification. This modification is a conventional technique in the art, and those skilled in the art can obtain a shear thickening material that meets the corresponding requirements through conventional experimental procedures based on the content disclosed in this utility model. The "unstressed condition" refers to the state when the arch support block 200 and the upper midsole 100 are combined and not in use, that is, when not stepped on by the user.

[0051] Reference Figures 3 to 6The arch support block 200 has an inner wall 210 and an outer wall 220 that extend upwards in an arched shape in the front-back direction to form a side wall 222 that is higher than the middle part of the arch support block 200 in the left-right direction. A support area 230 that matches the shape of the arch part is defined on the upper surface of the arch support block 200. The outer wall 220 is recessed towards the inner wall 210 and has a hollow groove 240 that extends in the front-back direction. The hollow groove 240 has a plurality of support arms 245 that extend in the left-right direction and are arranged in the front-back direction. The support arms 245 divide the hollow groove 240 into a plurality of hollow holes 247 that are arranged in the front-back direction and are not interconnected. The inner wall 210 has a plurality of first reinforcing ribs 250 that extend in the vertical direction to connect the upper and lower edges of the inner wall 210 and are arranged in the front-back direction.

[0052] Specifically, in this embodiment, the sole is for the left foot; therefore, its inner side corresponds to the right side in the attached drawing, and its outer side corresponds to the left side. The inner wall 210 is formed on the right side of the arch support block 200, and the outer wall 220 is formed on the left side of the arch support block 200. Both the inner wall 210 and the outer wall 220 extend upwards in an arched shape along the front-to-back direction, as detailed in the attached drawing. Figure 3 and Figure 4 The arch support block 200 exhibits a thickness variation in the left-right direction, being thinner in the middle and thicker on both sides. Specifically, it has greater thickness at the inner wall 210 and outer wall 220, formed by the upward extension of the inner and outer walls 210 and 220. Furthermore, the upward extension of the inner and outer walls 210 and 220 is not uniform across their front-back direction, but rather extends more upward at their middle position, thus forming an upwardly convex arch shape on the projection plane perpendicular to the left-right direction. This arch shape is defined by the upper and lower edges of the inner and outer walls 210 and 220. The upper edges of the inner and outer walls 210 and 220 respectively form the inner upper edge 211 and the outer upper edge 221. The lower edges of the inner and outer walls 210 and 220 are essentially flush with the bottom surface of the arch support block 200. The upper surface of the arch support block 200 defines a support area 230 that conforms to the shape of the human foot arch. This support area 230 includes a generally flat portion in the middle and sidewalls 222 located on the left and right sides formed by inner sidewalls 210 and outer sidewalls 220. The two sidewalls 222 smoothly transition into the flat portion in the upper surface of the arch support block 200 constituting the support area 230.

[0053] Furthermore, referring to Figure 6The arch support block 200 is integrally formed in the left-right direction by an inner support part 261 near the inner side and an outer support part 262 near the outer side; the front edge 264 and the rear edge 265 of the arch support block 200 are respectively curved and protrude backward and forward, and the line connecting the two closest positions in the front-back direction forms the dividing line 263 of the inner support part 261 and the outer support part 262; the dividing line 263 of the inner support part 261 and the outer support part 262 is closer to the outer side wall 220 in the left-right direction.

[0054] Specifically, the arch support block 200 is a one-piece molded structure, comprising an outer support portion 262 on the left and an inner support portion 261 on the right, with a dividing line 263 between them. The front edge 264 and rear edge 265 of the arch support block 200 are respectively curved, protruding backward and forward. The curved structure of the front edge 264 extends rightward and backward from the front end of the outer wall 220, reaching the dividing line 263, and then curves forward to reach the front end of the inner wall 210. The curved structure of the rear edge 265 extends rightward and forward from the rear end of the outer wall 220, reaching the dividing line 263, and then curves backward to reach the rear end of the inner wall 210. Thus, the arch support block 200 is formed in a shape roughly "X" in top view.

[0055] Furthermore, on a projection plane perpendicular to the left-right direction, the projected shape of the outer sidewall 220 lies within the projected shape of the inner sidewall 210 in the front-back direction. Also, on a projection plane perpendicular to the left-right direction, the upper edge of the projected shape of the inner sidewall 210 is higher than the upper edge of the projected shape of the outer sidewall 220. Specifically, refer to... Figure 6 The front end of the inner wall 210 is further forward than the front end of the outer wall 220, and the rear end of the inner wall 210 is further backward than the rear end of the outer wall 220. Meanwhile, referring to... Figure 5 The highest point of the upper edge of the medial wall 210 is higher than the highest point of the upper edge of the lateral wall 220 in the vertical direction. This shape and size limitation allows the arch support block 200 to better fit the core support area of ​​the foot, avoiding excessive restriction on unnecessary areas of the lateral side of the foot, thereby improving wearing comfort and movement flexibility. Furthermore, the higher medial wall 210 provides a larger resistance arm when the foot tends to roll inward, thus generating a more effective corrective torque. This asymmetrical height design greatly enhances the sole's ability to resist excessive pronation.

[0056] Reference Figure 3 and Figure 4A perforated groove 240 is formed on the outer wall 220. This perforated groove 240 is approximately wedge-shaped, meaning it is thicker on the left and thinner on the right in the thickness direction. Furthermore, corresponding to the structure of the front edge 264 and rear edge 265 of the arch support block 200, the perforated groove 240 is approximately wider on the left and narrower on the right in a projection plane perpendicular to the vertical direction. Multiple support arms 245 are provided within the perforated groove 240. These support arms 245 extend in the left-right direction and are arranged in the front-back direction. Simultaneously, these support arms 245 connect to the two side walls of the perforated groove 240 in the vertical direction, thereby dividing the perforated groove 240 into multiple non-communicating perforated holes 247. In this embodiment, there are four support arms 245, with three larger perforated holes 247 located in the middle and two smaller perforated holes 247 located at the front and rear ends.

[0057] Furthermore, the bottom of the hollowed-out groove 240 is positioned no more than the boundary line 263 between the inner support portion 261 and the outer support portion 262 in the left-right direction. This arrangement ensures that the inner support portion 261, as the main support area, has a complete structure and the highest rigidity, enabling it to fully undertake the task of supporting the inner longitudinal arch. At the same time, the function of providing flexible deformation is strictly controlled in the outer support portion 262, ensuring the realization of the support effect of the entire arch support block 200.

[0058] Reference Figure 5 A plurality of first reinforcing ribs 250 are formed on the inner sidewall 210. The first reinforcing ribs 250 protrude from other parts of the inner sidewall 210 and extend from the lower edge of the inner sidewall 210 to the upper edge of the inner sidewall 210.

[0059] Furthermore, referring to Figure 3 and Figure 4 The outer wall 220 forms a first groove wall 241 on the lower side and a second groove wall 242 on the upper side through the hollow groove 240. The first groove wall 241 extends perpendicularly to the vertical direction. The second groove wall 242 includes a first wall surface 243 extending perpendicularly to the vertical direction and a second wall surface 244 that connects to the first wall surface 243 and extends from bottom to top. The second wall surface 244 is located outside the first wall surface 243 relative to the bottom of the hollow groove 240, and the support arm 245 extends on the second wall surface 244 to form a second reinforcing rib 246 on the outer wall 220.

[0060] Specifically, the slot 240 is formed within the outer support portion 262, and the outer wall 220 is only a portion of the second wall surface 244 of the slot 240. The lower side wall of the slot 240 forms the first wall 241, and the upper side wall forms the second wall 242. The two walls are arranged opposite to each other, and the main part of the support arm 245 is used to connect these two walls. The second wall 242 includes a first wall surface 243 and a second wall surface 244. The first wall surface 243 and the first slot wall 241 extend roughly along the horizontal plane, but because the arch support block 200 is thicker on the left and right sides, the second wall surface 244 of the second slot wall 242 is designed to extend upwards. At the position of the second wall surface 244, the support arm 245 continues to extend along the second wall surface 244. At this time, the part of the support arm 245 located on the second wall surface 244 forms the second reinforcing rib 246. The second reinforcing rib 246 extends upward until it connects to the upper edge of the outer wall 220, that is, to the upper edge of the second wall surface 244.

[0061] Furthermore, referring to Figure 3 and Figure 5 The first reinforcing rib 250 and the second reinforcing rib 246 extend obliquely forward and backward in a relatively vertical direction, respectively, before and after the highest point of the upper edge of the inner sidewall 210 and the outer sidewall 220. Specifically, there are four of each type of reinforcing rib. For the inner sidewall 210 and the outer sidewall 220, two are located in front of the highest point of the upper edge of the sidewall 222, and two are located behind the highest point of the upper edge of the sidewall 222. The two first reinforcing ribs 250 and 246 located in front extend slightly obliquely from bottom to top and from back to front, and the two first reinforcing ribs 250 and 246 located behind extend slightly obliquely from bottom to top and from front to back. By designing the first reinforcing rib 250 and the second reinforcing rib 246 into an arched profile that extends obliquely forward and backward at the highest point, the arched structure can more effectively decompose the vertical load into pressure along the axial direction of the component, allowing the reinforcing ribs to transmit and disperse the downward pressure from the arch of the foot in the most efficient way, thereby providing a stronger support effect with the same amount of material.

[0062] In addition, refer to Figure 4 , Figure 7 and Figure 8The upper surface of the arch support block 200 is provided with a plurality of first fitting portions 271 in the portion of the inner support portion 261; the lower surface of the upper midsole 100 is provided with a plurality of second fitting portions 111; the first fitting portions 271 and the second fitting portions 111 are adapted to fit together when the arch support block 200 is combined with the upper midsole 100. In this embodiment, the first fitting portions 271 are a plurality of recessed structures provided on the upper surface of the arch support block 200. These recessed structures are generally cylindrical and are arranged in a plurality of spaces along the front-back direction and in two rows spaced apart in the left-right direction. Correspondingly, the second fitting part 111 consists of multiple protruding structures on the bottom of the composite groove 110 of the upper midsole 100. These protruding structures are adapted to the shape and size of the recessed structure of the first fitting part 271, and their positions correspond one-to-one. This allows the first fitting part 271 and the second fitting part 111 to fit together after the arch support block 200 is attached to the upper midsole 100. This interlocking structure effectively resists shear forces generated during movement, preventing relative sliding between the two components. This ensures that the arch support block 200 is always in the correct position, thereby ensuring the stability of the arch support function.

[0063] This embodiment relates to a dynamic arch support sole, which addresses the core problem that existing arch support devices cannot simultaneously satisfy the needs of comfort during low-intensity exercise and protection during high-intensity exercise. This solution achieves adaptive changes in the mechanical properties of the arch support in the sole through the synergistic effect of materials and structure. Firstly, the sole of this invention consists of a functionally separated upper midsole 100 and an arch support block 200. The arch support block 200 uses a shear-thickened material, and its hardness when unloaded is set higher than that of the upper midsole 100. Because the hardness of the arch support block 200 is higher than the weight of the upper layer, and because the arch support block 200 is located below the upper midsole 100 and corresponds to the user's arch area, the arch support block 200 can effectively resist the deformation of the sole caused by stress. When the user is standing, the arch support block 200, relying on its inherently high modulus, provides a stable support platform for the arch, preventing it from collapsing under body weight. When the user performs high-intensity exercises such as running and jumping, the ground impact force is a high-strain-rate load. The physical properties of shear-thickened materials determine that their internal molecular network will momentarily lock under high strain rates, leading to a sharp increase in the material's viscoelastic modulus. This means that the overall stiffness of the arch support block 200 will significantly increase at the moment of impact, thus providing higher support force than in the static state to resist greater impact loads. This allows the sole's support performance to adaptively adjust according to changes in external load. Secondly, the structural design of the arch support block 200 effectively translates these material properties into functionality. Its inner wall 210 and outer wall 220 extend upwards, forming a sidewall 222 structure that physically applies lateral restraint to the foot, limiting excessive displacement in the left-right direction and improving stability during movement. The first reinforcing rib 250 on the inner wall 210 essentially increases the second moment of the cross-section in this area, improving the inner wall 210's resistance to bending deformation, thereby more effectively supporting the medial longitudinal arch and preventing it from collapsing under high loads. Crucially, the perforated groove 240, support arm 245, and perforated hole 247 structure on the outer side wall 220 solves the problems of insufficient flexibility and lack of gait guidance that may result from using rigid dynamic materials. If both the inner and outer sides use the same robust reinforcing structure, the entire support block would be too rigid, hindering the necessary and natural deformation of the foot upon landing, and also failing to intervene in poor gait. The perforated structure of this invention, by removing material, actively reduces the overall structural stiffness of the outer side wall 220, making it lower than that of the rigid inner side wall 210. This resolves the contradiction between rigidity and flexible control. When the foot tends to roll inward, this relatively flexible outer structure can undergo greater controllable compressive deformation than the inner side, thereby generating a corrective torque to counteract excessive pronation.Meanwhile, the support arm 245 in the hollowed-out groove 240 serves to connect and transfer loads, preventing the outer wall 220 from failing due to excessive hollowing, thus ensuring that it provides both flexibility and necessary support. Therefore, the dynamic arch support sole provided by this solution, through deep coupling of materials and structure, enables the sole to provide adaptive support and stability functions that cannot be achieved by existing technologies, offering good comfort during normal wear and excellent support performance during high-speed exercise.
