Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a support for enhancing arch support, and a sole and a shoe containing the support for enhancing arch support. Background Technique

[0002] In recent years, with the rise of national fitness, the running craze has gradually emerged. More and more sports enthusiasts regard running as their first choice of sport, and running is also one of the most popular physical activities around the world.

[0003] During exercise, as the carrier for the runner's feet to contact the ground, running shoes bear a ground impact force that is 3 to 4 times the runner's own body weight. The functionality of sports shoes is mainly achieved by the combination of different materials and structures, and the research on the multi-layer composite sole structure is also a key research direction for the development of sports shoes.

[0004] The sole of a running shoe consists of a midsole and an outsole. Among them, the midsole is the part that shoe manufacturers focus on the most. It has a solid structure and a hollow structure. The cushioning and shock absorption performance and support stability of running shoes are also provided by the structural design of the midsole part.

[0005] Previously, the multi-layer composite structure of running shoes was mainly divided into: 1. Stacked by multiple foaming materials; 2. Foaming material + support structure. This support structure is generally located inside the midsole, and there is a one-piece support structure and an upper and lower two-piece support structure. At present, there are several ways to make the midsole. The midsole material is first foamed and then the support structure is inserted into the midsole. The process of the upper and lower two-piece support structure is more complicated. However, the existing shoe-making technical solutions all have the following problems: 1. Most shoes vigorously develop new supercritical foaming materials to improve stability, shock absorption and rebound performance, ignoring the influence of the midsole structure on the shoe performance; 2. The midsole material is first foamed and formed, and then combined with the support sheet for combination, which results in higher shoe-making costs and longer time.

[0006] For current carbon plate running shoes, the mainstream method is to insert a shovel-shaped carbon plate into the midsole. It has the advantages of high longitudinal bending stiffness and good midsole rebound performance. Because the carbon plate of this kind of running shoe is a whole piece similar to a spoon shape, when the runner touches the ground to the pushing-off stage, due to the shape of the carbon plate, the inner side of the foot cannot provide proper support. Therefore, it requires the runner to reach a certain level, especially for runners participating in full marathon races. Some studies have pointed out that the height of the navicular bone drops by 5 mm after a half marathon and 4.8 mm after a full marathon on the first day, which is likely to produce incorrect movement patterns, thereby causing injuries or being injured and affecting sports performance.

[0007] Therefore, it is of positive significance to design a running posture suitable for the general runners who land on the mid-forefoot, provide them with appropriate foot support and propulsion performance during pushing off, and integrally mold this structure with the midsole material to make the force transmission smoother and reduce the shoe manufacturing cost. Summary of the Invention

[0008] The purpose of the present utility model is to provide a runner suitable for the running posture of landing on the mid-forefoot, and provide a support member, a sole and a shoe for improving the foot support and forefoot propulsion performance and arch support. The support member is integrally molded with the midsole material, which can reduce the weight, reduce the shoe manufacturing cost and make the force transmission smoother. The specific technical solutions are as follows:

[0009] A support member for improving arch support includes a forefoot region, a midfoot region and a heel region. A bifurcation region is arranged in the forefoot region, and a dividing groove is arranged from the bifurcation region towards the heel region. The dividing groove divides the midfoot region and the heel region of the support member into a first elastic part and a second elastic part. The first elastic part is located above the second elastic part, and the first elastic part and the second elastic part are arranged at an angle from the bifurcation region towards the heel region. A hollow first region is formed in the midfoot region of the first elastic part, and the area of the second elastic part is larger than the area of the first region.

[0010] Further, the width of the second elastic part is greater than the width of the first region in the first elastic part, and the width of the second elastic part gradually increases from front to back.

[0011] Further, the length of the second elastic part is greater than the length of the first region in the first elastic part, and the part of the length that is greater is located in the heel region of the second elastic part.

[0012] Further, the length of the second elastic part accounts for 50% - 70% of the length of the support member.

[0013] Further, the midfoot region of the first elastic part is arranged to fit the arch shape to form a first arc structure, and the forefoot region of the support member and the second elastic part are continuous curved surfaces at the bifurcation region to form a second arc structure.

[0014] Further, a first reinforcing rib is arranged on the inner side of the first elastic part, and the first reinforcing rib is arranged in the forefoot region and the midfoot region of the support member.

[0015] Further, a second reinforcing rib is arranged on the outer side of the first elastic part, and the second reinforcing rib is arranged in the forefoot region and the midfoot region of the support member.

[0016] Further, a third reinforcing rib and a fourth reinforcing rib are arranged on the second elastic part, and the third reinforcing rib and the fourth reinforcing rib are arranged in the midfoot region of the support member.

[0017] Further, a hollow second region is arranged in the heel region of the first elastic part.

[0018] Further, the forefoot area includes a first bifurcated portion and a second bifurcated portion, and a hollow third area disposed between the first bifurcated portion and the second bifurcated portion.

[0019] Further, the first bifurcated portion corresponds to the first metatarsal area of the human foot, the third area corresponds to the second and third metatarsal areas of the human foot, and the second bifurcated portion corresponds to the fourth and fifth metatarsal areas of the human foot.

[0020] Further, the length of the first bifurcated portion is greater than the length of the second bifurcated portion.

[0021] A sole includes the above-mentioned support member, a first elastic layer, a second elastic layer, and an outsole. The first elastic layer, the support member, and the second elastic layer are integrally formed structures.

[0022] Further, it further includes an attachment material layer disposed between the heel areas of the first ejection portion and the second ejection portion, so that the attachment material layer and the midfoot area of the support member form a hollow chamber. The first elastic layer includes a forefoot portion, a midfoot portion, and a heel portion. The midfoot portion includes a first support sidewall, and the heel portion includes a second support sidewall and a support structure.

[0023] A shoe includes the above-mentioned sole.

[0024] The support member, sole, and shoe for enhancing arch support of the present utility model have the following advantages:

[0025] 1. The first ejection portion and the second ejection portion are arranged at an angle from the bifurcated area towards the heel area. The formed angle can adapt to different people and age groups. This intermediate bifurcated structure increases deformation and stores more energy, providing appropriate foot support for runners and thus increasing the rebound performance.

[0026] 2. Longitudinal reinforcing ribs are respectively arranged in the front-rear direction on the first ejection portion and the second ejection portion of the support member. The combination of these reinforcing ribs and the arc design of the intermediate support member is beneficial to increasing the stability of the ankle joint.

[0027] 3. The arrangement of the reinforcing ribs and the upper and lower bifurcation of the intermediate support member on the support member is beneficial to increasing the propulsion performance. This structure forms a step-by-step pressure transmission mechanism, which is beneficial to the release of the impact force when the foot touches the ground, avoids stress concentration, reduces the risk of the support piece breaking, and provides appropriate foot support.

[0038] In order to better understand the purpose, structure and function of the present utility model, the support member, sole and shoe for enhancing the arch support of the present utility model will be described in detail below with reference to the accompanying drawings.

[0039] As Figure 1As shown, the support member 100 for improving arch support includes a forefoot area 110, a midfoot area 120 and a heel area 130 which are connected in sequence, and the side of the support member 100 body close to the inner side of the human foot is defined as the inner side of the support member 100 body, the side of the support member 100 body close to the outer side of the human foot is defined as the outer side of the support member 100 body, the end of the support member 100 body close to the toe of the human foot is defined as the front side of the support member 100 body, and the end of the support member 100 body close to the heel of the human foot is defined as the rear side of the support member 100 body. A bifurcated area 140 is provided in the front midfoot area 120 behind the area 110, and a dividing groove is provided from the bifurcated area 140 toward the heel area 130. The dividing groove divides the midfoot area 120 and the heel area 130 of the support member 100 into a first ejection portion 150 and a second ejection portion 160. The first ejection portion 150 is located above the second ejection portion 160. The first ejection portion 150 and the second ejection portion 160 are arranged at an angle from the bifurcated area 140 toward the heel area 130. The angle formed can adapt to people of different groups and age groups and provide them with appropriate foot support effects. Among them, the second ejection portion 160 is located in the rear half of the forefoot bending point. When the foot lands on the ground, the pressure of the arch and the sole first acts on the upwardly tilted first ejection portion 150, and then is transmitted to the second ejection portion 160. This structure forms a step-by-step pressure transmission mechanism, which is conducive to the release of impact force when the foot lands, avoids stress concentration, reduces the risk of support sheet fracture, and provides appropriate foot support.

[0040] At the same time, longitudinal reinforcement ribs are respectively arranged on the first ejection part 150 and the second ejection part 160 of the support member 100 along the front-to-back direction. Due to the split angle design of the first ejection part 150 and the second ejection part 160, which is different from the existing shovel-type support member, when a runner of normal weight lands on the middle and forefoot, the first ejection part 150 can deform downward to disperse the impact force on the landing foot, and the reinforcement ribs arranged on the first ejection part 150 can provide foot support and reduce the risk of injury. In the foot extension stage, the reinforcement ribs close to the inside can provide a supporting effect. Finally, combined with the reinforcement ribs on the second ejection part 160, support is provided for the propulsion force required by the runner during extension, thereby improving athletic performance and reducing the burden on the runner.

[0041] In summary, the support member 100 for improving arch support provided by the utility model increases deformation by setting a middle fork structure to store more energy, thereby increasing rebound performance. The curvature of the middle support member 100 and the design of the reinforcing ribs are beneficial to increasing ankle joint stability. The reinforcement ribs provided on the support member 100 and the upper and lower forks of the middle support member 100 are beneficial to increasing propulsion performance.

[0042] To better understand the purpose, structure, and function of the present utility model, the following will further describe in detail the support member for enhancing arch support, the sole, and the shoe of the present utility model by taking the specific structures of the support member for enhancing arch support and the sole as examples in conjunction with the accompanying drawings.

[0043] In the first embodiment of the present utility model, as Figures 1 to 4 shown, the support member 100 for enhancing arch support includes a forefoot region 110, a midfoot region 120, and a heel region 130. A bifurcated region 140 is provided within the forefoot region 110. A U-shaped dividing groove is provided extending from the bifurcated region 140 towards the heel region 130. The opening of the U-shaped dividing groove is located within the bifurcated region 140. The dividing groove divides the midfoot region 120 and the heel region 130 of the support member 100 into a first elastic part 150 and a second elastic part 160. A hollow first region 155 is formed in the midfoot region 120 of the first elastic part 150. The first elastic part 150 is located above the second elastic part 160. The first region 155 corresponds to the second elastic part 160. The first elastic part 150 and the second elastic part 160 are arranged at an angle extending from the bifurcated region 140 towards the heel region 130 to form a stepped pressure transmission mechanism, which is beneficial for releasing the impact force when the foot touches the ground, avoiding stress concentration, reducing the risk of the support piece breaking, and providing appropriate foot support.

[0044] Furthermore, as Figure 2 shown, a first reinforcing rib 151 is provided on the inner side of the first elastic part 150, and a second reinforcing rib 152 is also provided on the outer side of the first elastic part 150. Both the first reinforcing rib 151 and the second reinforcing rib 152 are longitudinally arranged from front to back and are provided corresponding to the forefoot and arch regions of the human foot. This structure is applicable to runners with a larger body weight. Because of their larger body weight, when the foot touches the ground, there is a higher demand for lateral support of the foot. Therefore, a second reinforcing rib 152 is also provided on the outer side of the first elastic part 150 to provide sufficient support, reducing the risk of runner injury, and at the same time providing a certain amount of rebound assistance on the outer side during the extension stage to improve the runner's athletic performance.

[0045] Furthermore, as Figure 3As shown, a first arc structure 121 is provided in the midfoot area 120 of the first ejection part 150. The first arc structure 121 arches upward and conforms to the shape of the human foot arch. Thus, it supports the arch area during landing on the inner and outer sides of the first ejection part 150, stores corresponding energy, and releases it during the extension phase in conformity with the foot arch to reduce the risk of injury and improve sports performance. At the same time, the forefoot area 110 of the support member 100 and the second ejection part 160 are smoothly transitioned through a continuous curved surface at the bifurcation area 140 to form a second arc structure 122 that arches downward, that is, the forefoot area 110 and the second ejection part 160 are a continuous curved surface structure. Thus, there is no stress concentration area at the bottom of the support member 100, and the pressure transmitted downward through the first ejection part 150 is quickly and evenly dispersed to the forefoot area 110 and the second ejection part 160 to improve the effect of the step-by-step pressure transmission mechanism, relieve the pressure on the human foot, and reduce the risk of injury.

[0046] Preferably, the forefoot area 110 includes a first bifurcation part 111 and a second bifurcation part 112, and a hollow third area 113 provided between the first bifurcation part 111 and the second bifurcation part 112. The third area 113 is a U-shaped groove with an opening facing forward. Thus, a bifurcated structure with inner and outer sides is formed at the front end of the forefoot area 110. According to the force application characteristics of the human body during the extension phase of running, the first bifurcation part 111 and the second bifurcation part 112 are provided in the inner and outer areas where the pressure is concentrated, so as to enhance the support effect and contribute to the force application of the forefoot area 110 during the extension phase.

[0047] Furthermore, as Figure 2 shown, the shapes of the first bifurcation part 111 and the second bifurcation part 112 are asymmetrically arranged. Based on the fact that the pressure rise on the inner side of the forefoot during the extension phase is the largest, the first bifurcation part 111 corresponds to the first metatarsal area of the human foot, and the second bifurcation part 112 corresponds to the fourth and fifth metatarsal areas of the human foot. The length of the first bifurcation part 111 is greater than the length of the second bifurcation part 112 to facilitate sufficient support effect on the inner side of the forefoot area 110, thereby improving the sports performance during the extension phase. Based on the fact that the stress in the second and third metatarsal areas is the largest during the extension phase, the third area 113 corresponds to the second and third metatarsal areas of the human foot. The third area 113 of the forefoot area 110 is hollow, which can better disperse the impact force received by the foot during landing, and the bifurcated structure can reduce the longitudinal bending stiffness of the forefoot area 110 and improve the flexibility of the forefoot.

[0048] Preferably, as Figure 4As shown, the width of the second elastic part 160 gradually increases from front to back. The width of the heel area 130 of the second elastic part 160 is greater than the width of the first area 155 in the first elastic part 150. That is, a part of the first elastic part 150 outside the heel area 130 of the first area 155 corresponds to the second elastic part 160 in the longitudinal direction. Thus, the greater width of the heel area 130 of the second elastic part 160 increases the support force of the heel area 130, improves the stability and shock absorption of the heel during the landing to touchdown period. At the same time, the wider heel area 130 of the second elastic part 160 helps to enhance the stability of the elastic layer provided on the second elastic part 160.

[0049] As Figure 2 and Figure 3 shown, the length of the second elastic part 160 is greater than the length of the first area 155 in the first elastic part 150. Specifically, in the heel area, the second elastic part 160 is closer to the rear side of the support member than the first area 155. Thus, the part of the second elastic part 160 that extends beyond the first area 155 at the rear end can enhance the support for the human heel area. Furthermore, combined with the width setting of the heel area 130 of the second elastic part 160 described above, a second elastic part 160 with a width and length both greater than those of the first area 155 is formed. That is, the area of the second elastic part 160 is greater than the area of the first area 155, so as to provide support to both sides of the midfoot and the heel of the foot and prevent excessive inward or outward rotation of the foot.

[0050] Furthermore, the first elastic part 150 is provided with a hollowed-out second area 156 in the heel area 130. The heel area 130 of the second elastic part 160 is arranged opposite to the second area 156 of the first elastic part 150. The second area 156 is a U-shaped groove with an opening facing backward, which helps to reduce the weight of the support member 100 and is conducive to more conveniently injecting the elastic layer material during integral molding. In addition, it can hold the calcaneus of the heel while combining with the highly elastic attachment material layer 201 to further improve the stability and shock absorption of the heel during the landing to touchdown period.

[0051] Preferably, the second elastic part 160 starts to bifurcate downward at a position 50% - 70% of the straight-line distance from the heel to the forefoot of the support member 100. That is, the length of the second elastic part 160 accounts for 50% - 70% of the length of the support member 100. The bifurcated area 140 is located in the second half of the forefoot bending point, which is beneficial to the release of the impact force when the foot touches the ground, avoids stress concentration, better reduces the risk of the support piece breaking, and provides appropriate foot support.

[0052] The second embodiment of the present invention, as Figure 5As shown, the overall structure of the support member 100 is the same as that of the first embodiment. Different from the first embodiment, only the first reinforcing rib 151 is provided inside the first ejection portion 150, and the second reinforcing rib 152 is not provided outside the first ejection portion 150 to accommodate runners with a lighter weight. Because of their lighter weight, when the foot touches the ground, the need for lateral support of the foot is not high, so no reinforcing rib is provided on the outside. However, during the extension stage, the inside of the foot needs support. Therefore, the first reinforcing rib 151 is provided inside the first ejection portion 150 to reduce the risk of runner injury and improve running comfort at the same time.

[0053] The third embodiment of the present utility model, as Figure 6a and Figure 6b shown, the overall structure of the support member 100 is the same as that of the first embodiment. Different from the first embodiment, no reinforcing ribs are provided inside and outside the first ejection portion 150, and the third reinforcing rib 153 and the fourth reinforcing rib 154 are provided in the middle of the second ejection portion 160. The third reinforcing rib 153 and the fourth reinforcing rib 154 are longitudinally arranged from front to back and are arranged corresponding to the arch area of the human foot. This structure is applicable to runners who land on the forefoot or in the case where the physical strength does not significantly decline during short-distance running. In the above cases, the runners land on the forefoot, so the need for support on both sides of the arch is not high. Therefore, only the third reinforcing rib 153 and the fourth reinforcing rib 154 are provided on the second ejection portion 160, which can provide sufficient support to the arch during the extension stage and improve the sports performance of the runners.

[0054] Those skilled in the art can, according to the actual situation, set other numbers of reinforcing ribs on the second ejection portion 160, or arbitrarily combine the numbers of reinforcing ribs provided on the first ejection portion 150 and the second ejection portion 160, as long as it can provide sufficient support, reduce the risk of runner injury, and provide a certain amount of rebound assistance during the extension stage to achieve the effect of improving the sports performance of the runners.

[0055] The present utility model provides a shoe sole 200, including the support member 100 for enhancing arch support, the first elastic layer 210, the second elastic layer 220, and the outsole 230 described above. The first elastic layer 210, the support member 100, the second elastic layer 220, and the outsole 230 are sequentially overlapped to form the main body of the shoe sole 200. In addition, the overlapping order of the first elastic layer 210, the second elastic layer 220, and the support member 100 from top to bottom can also be: the first elastic layer 210, the second elastic layer 220, the support member 100, or the support member 100, the first elastic layer 210, and the second elastic layer 220.

[0056] As Figures 7 to 9As shown, the preferred embodiment is that the first elastic layer 210, the support member 100, the second elastic layer 220, and the outsole 230 are sequentially overlapped. According to the previous shoe biomechanics and human trial results, this preferred overlapping method is beneficial to the production process, provides a better comfortable foot feeling and force feedback feeling. Specifically, the first elastic layer 210 located at the top layer can closely fit with the human foot to provide a more comfortable foot feeling. The support member 100 can provide a strong support effect for the human foot arch. The second elastic layer 220 can provide shock absorption and buffering functions at the lower layer of the sole 200.

[0057] Further, as Figure 8 shown, it further includes an attachment material layer 201. The attachment material layer 201 is disposed between the heel region 130 of the first ejection part 150 and the heel region 130 of the second ejection part 160. The attachment material layer 201 provides an upward support and rebound effect for the first ejection part 150. A hollow chamber 202 is formed by enclosing the front side of the attachment material layer 201, the lower surface of the first ejection part 150, and the upper surface of the second ejection part 160. The inside and outside of the hollow chamber 202 are communicated to reduce the overall weight of the sole 200. At the same time, the hollow chamber 202 can be compressed and deformed to provide appropriate arch support for ordinary runners who land on the middle and front of the foot, and store energy at the same time, helping to quickly release the energy during the extension stage, making the sports rebound effect faster and more significant, and effectively reducing the risk of injury to the knee joint and ankle joint. Of course, according to actual needs, the attachment material layer 201 can also not be provided, which can further reduce the weight of the sole 200.

[0058] Further, the first elastic layer 210 of the sole 200 includes a forefoot part 211, a midfoot part 212, and a heel part 213. First support sidewalls 214 extend upward on both sides of the midfoot part 212 to provide support and protection for the foot. A second support sidewall 215 is disposed around the heel part 213 to prevent the inward and outward turning of the foot when landing, effectively preventing the inward and outward turning phenomenon of the runner at the moment of landing. A support structure 216 is disposed at the rear side of the heel part 213 to provide shock absorption and rebound functions during running.

[0059] Preferably, the first elastic layer 210, the support member 100 and the second elastic layer 220 in the sole 200 are integrally formed structures. Among them, the first elastic layer 210 and the second elastic layer 220 are prepared by a supercritical foaming or chemical foaming molding process using an elastomer. In the supercritical foaming process, one of nylon elastomer (PEBA), polyurethane elastomer (TPU), and polyester elastomer (TPEE) can be used; in the chemical foaming process, a composition of one or more of polyethylene-vinyl acetate (EVA), polyolefin block copolymer (OBCs), polyethylene-octene copolymer (POE), ethylene propylene diene monomer (EPDM), and styrene block copolymer (SEBS) can be selected. The material is light, soft and elastic, and can provide excellent shock absorption and rebound effects for the heel to the forefoot 211 position of the human foot during running.

[0060] The material of the above-mentioned support member 100 can be at least one of nylon (PA), nylon elastomer (PEBA), polyurethane (TPU), polyester (PC), and polyester elastomer (TPEE); it can also be a composite material composed of any one of the above materials and inorganic or organic fillers such as glass fiber, carbon fiber, and aramid fiber.

[0061] For the above-mentioned outsole 230, according to a reasonable formula design, an outsole 230 material with excellent anti-slip and fatigue wear resistance is prepared. Using the thinnest thickness as the outsole 230 can meet the actual running exercise requirements, effectively reduce the thickness and weight of the sole 200, realize the functional requirement of shoe lightweight, and provide a better wearing experience for the wearer. The outsole 230 material is at least one of blended rubber, millable polyurethane, and thermoplastic polyurethane; the blended rubber includes but is not limited to natural rubber, styrene-butadiene rubber, cis-1,4-polybutadiene rubber, nitrile rubber, ethylene-propylene rubber, and chloroprene rubber.

[0062] Regarding the first embodiment of the present invention, materials with the following characteristics are used in combination with the support plate to provide the optimal force feedback performance, specifically as follows:

[0063] The elastic layer foaming material is selected as nylon elastomer material, with a density of 0.14 g / cm 3 , a rebound of 72%, PeakG 10.67; a yellowing resistance of 4 levels; providing a light + high-elastic effect.

[0064] The support member 1002 is a rigid support plate, which can be at least one of nylon (PA), nylon elastomer (PEBA), polyurethane (TPU), polyester (PC), and polyester elastomer (TPEE); it can also be a composite material composed of any one of the above materials and inorganic or organic fillers such as glass fiber, carbon fiber, and aramid fiber, with a total thickness of 1.0 - 2.5 mm.

[0065] The outsole 230, which is made of cast polyurethane, has excellent abrasion resistance and anti-slip performance, and its performance is as follows: DIN abrasion resistance is 30 mm 3 , the dry anti-slip coefficient is 0.9, and the wet anti-slip coefficient is 0.55. In other embodiments, the selectable range of density is: 0.11~0.18 g / cm 3 , the resilience is 68~76%, Peak G is 12.0~9.0; the yellowing resistance is grade 4. The DIN abrasion resistance of the outsole 230 is 30~100 mm 3 ; the dry slip is 0.7~1.2; the wet slip is 0.45~0.7.

[0066] The present utility model also provides a shoe, which includes the sole 200 containing the support member 100 with enhanced arch support as described above.

[0067] The embodiment one of the present utility model and a common spatula-shaped support plate shoe model are compared and tested. The materials of the two shoes are basically the same, and the difference lies in the arc and structure of the middle support member 100. The right-foot biomechanical parameter indexes of multiple runners on a treadmill at the same speed are tested, and the specific details are as follows:

[0068]

[0069] It can be seen from the above experimental results that the midfoot energy resilience of the shoe model of embodiment one is greater than that of the common spatula-shaped support plate shoe model. This is because the upper and lower bifurcations of the middle support member 100 in embodiment one increase the deformation, thus storing more energy and further increasing the resilience performance.

[0070] The range of ankle varus and valgus, the maximum valgus angle of the ankle joint, and the maximum valgus speed of the ankle joint of the shoe model of embodiment one are smaller than those of the common spatula-shaped support plate shoe model. This is because the arc of the middle support member 100 and the design of the reinforcing ribs in embodiment one are beneficial to increasing the stability of the ankle joint.

[0071] The forward peak force during the extension phase of the shoe model of embodiment one is greater than that of the common spatula-shaped support plate shoe model. This is because the special reinforcing rib design and the design of the upper and lower bifurcations of the middle support plate in embodiment one are beneficial to increasing the propulsion performance.

[0072] In summary, the support member 100, the sole 200, and the shoe with enhanced arch support provided by the present utility model are suitable for ordinary runners with a mid-forefoot landing running posture, providing foot support and forefoot propulsion performance for them. The stepped mid-air midfoot structure is set according to the foot shape, which can further strengthen the midfoot support performance and reduce the risk of ankle and knee injuries. At the same time, the support member 100 and the elastic layer material are integrally formed, which can make the force conduction more smooth and has a positive significance for reducing the shoe manufacturing cost.
