Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to an ejection support, and a sole and a shoe containing the ejection support. Background Art

[0002] Running is a national sport, and people have put forward many requirements for running shoes. Among them, excellent shock absorption and rebound performance have always been the goals pursued in the research and development of running shoes, which is also an important way to reduce sports injuries and improve sports performance. However, the effects of the existing sole shock absorption and rebound designs are relatively limited, and there are still some problems:

[0003] First of all, most racing running shoes have a thick sole structure with a carbon plate embedded in the sole. When wearing a thick-soled carbon plate racing running shoe, during a forward single-leg landing jump, the overall dynamic stability is poor, and during a lateral single-leg landing jump, the dynamic stability in the left-right direction is poor. Therefore, it is easy to cause sports injuries during exercise; in addition, during long-distance running, such as a full marathon, the foot landing method of the runner in the second half will change continuously, transitioning from landing on the forefoot and midfoot to landing on the heel. At this time, during the transition from heel landing to midfoot, higher heel resilience and shock absorption are required to compensate for the decrease in muscle strength caused by lower limb and foot muscle fatigue in the second half. Existing running shoes cannot change the force feedback mechanism as the foot landing method changes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an ejection support frame, as well as a sole and a shoe containing the support, by respectively arranging upwardly curved structures in the corresponding forefoot area, midfoot, and heel area of the support to meet the functional requirements in different dimensions.

The first ejection part and the first shock absorption part are arranged at an angle, and the second ejection part and the second shock absorption part are arranged at an angle, thereby respectively forming an ejection space to provide a deformation space.

[0006] Further, two first dividing grooves are arranged on the first region. The first dividing grooves extend from the end of the first region close to the heel towards the other end in the toe direction, so as to form a first ejection part in the middle of the first region and first shock absorption parts on the inner and outer sides of the first region.

[0007] Further, one end of the first ejection part close to the toe part is upwardly curved in the vertical direction, so that the first ejection part is integrally inclined, and an ejection space is formed between the first ejection part and the first shock absorption part.

[0008] Furthermore, the first ejection portion corresponds to the second metatarsal and the third metatarsal of the human foot, the medial first shock-absorbing portion corresponds to the first metatarsal of the human foot, and the lateral first shock-absorbing portion corresponds to the fourth metatarsal and the fifth metatarsal of the human foot, so that the width of the first shock-absorbing portions on both sides is respectively smaller than the width of the first ejection portion.

[0009] Furthermore, the length of the first ejection part is smaller than that of the first cushioning part, the inner first cushioning part corresponds to the first toe of the foot, and the outer first cushioning part corresponds to the fourth toe and the fifth toe of the foot, so that the area of ​​the first area corresponding to the second toe and the third toe is hollowed out.

[0011] Furthermore, one end of the first ejection portion close to the heel is tilted upward in the vertical direction, so that the first shock absorbing portion is tilted as a whole and an ejection space is formed between the first ejection portion and the first shock absorbing portion.

[0012] Furthermore, the first shock-absorbing part is located in the middle position of the first area of ​​the ejection support part, and the first ejection parts are respectively arranged on both sides of the first shock-absorbing part. The first shock-absorbing part is connected to the first ejection part at one end close to the toe, and the first ejection part is arched toward the direction of the human foot to form an ejection space between the first shock-absorbing part and the first ejection part.

[0013] Furthermore, the second ejection part is arranged between the second area and the third area, the second shock absorbing part surrounds the outer side of the second ejection part, and one end of the second ejection part close to the heel is tilted upward in the vertical direction to form an ejection space between the second ejection part and the second shock absorbing part.

[0014] Furthermore, the first area, the second area and the third area of ​​the ejection support member are an integrally formed structure.

[0015] A shoe sole comprises the ejection support member mentioned above, wherein a first elastic layer is arranged above the ejection support member, and a second elastic layer is arranged below the ejection support member.

[0016] Furthermore, the first elastic layer includes a front sole, a midsole and a rear sole, a protective structure and a support column. The protective structure is extended upward from the inner and outer sides of the first elastic layer to limit the lateral movement of the human foot. The support column is arranged downward along the inner and outer sides of the rear sole, close to both sides of the second ejection part near the heel end.

[0017] Further, the second elastic layer includes a forefoot part, a midfoot part, and a heel part. A first elastic support part corresponding to the first elastic part of the first area is provided at the forefoot part, and a second elastic support part corresponding to the second elastic part is provided at the midfoot part.

By providing two deformation spaces front and back, it compensates for the decrease in muscle strength caused by fatigue of the lower limbs and feet in the second half of the process, changes the force feedback mechanism as the landing method of the foot changes, improves the overall dynamic stability of the foot, and avoids sports injuries.

[0041] In order to better understand the purpose, structure and function of the present invention, the ejection support member of the present invention, and the sole and shoe containing the ejection support member are described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, the ejection support member 1 is a support structure that takes into account the front and rear zoning requirements of the sole and provides targeted shock-absorbing and rebounding functions, including a first area 100, a second area 200, and a third area 300 that are sequentially connected in the direction from the toe to the heel, corresponding to the forefoot, midfoot, and heel positions of the human foot, respectively. The side of the sole body close to the inner side of the human foot is defined as the inner side of the sole body, and the side of the sole body close to the outer side of the human foot is defined as the outer side of the sole body.

[0043] A first dividing groove is provided in the first area 100, and the first dividing groove divides the first area 100 into a first ejection portion 101 and a first shock absorbing portion 102. The ejection portion is a convex structure arched toward the sole of the foot, and the convex structure undergoes elastic deformation, thereby storing or releasing energy along with the deformation, thereby providing a strong propulsion effect for the extension phase of the human foot.

[0044] The second region 200 and the third region 300 of the ejection support member 1 are provided with arc-shaped second dividing grooves, which divide the second region 200 and the third region 300 of the support member into a second ejection portion 201 and a second shock absorbing portion 202 .

[0045] The second ejection part 201 is tongue-shaped and is located in the middle area between the midfoot part 203 and the heel part 301. The second shock absorbing part 202 is semi-annular and is located at the outer edge of the midfoot part 203 and the heel part 301, surrounding the outer side of the second ejection part 201. One end of the second ejection part 201 close to the heel part 301 is tilted upward in the vertical direction, so that the second ejection part 201 is tilted as a whole, and an ejection space is formed between the second shock absorbing part 202 and the second ejection part 201.

[0046] During exercise, the heel of the human foot steps on the sole, causing the second ejection part 201 to be subjected to force. At this time, the second ejection part 201 presses down toward the second shock-absorbing part 202, compressing the ejection space, providing shock absorption and buffering effects for the human foot, and storing energy. When the human foot is lifted up, the second ejection part 201 and the second shock-absorbing part 202 restore their shapes under the action of elasticity, releasing the stored energy, and providing an upward and forward rebound and boosting effect for the human foot.

[0047] like Figure 2 As shown, the utility model provides a sole including the ejection support member 1 , wherein the sole includes an elastic layer, the ejection support member 1 , an outer sole 5 , and a heel stabilizing component 4 .

[0048] The elastic layer and the support member are stacked to form a sole body, and the sole body may include one elastic layer or two or more elastic layers; or the sole body may include one support member or two or more support members. The two or more elastic layers and the support member are staggered and overlapped to form a sole body with good resilience and shock absorption, and can effectively support the sole body.

[0049] like Figure 2 As shown, preferably, the sole includes a first elastic layer 2, an ejection support member 1, a second elastic layer 3 and an outsole 5 stacked in sequence from top to bottom. The first elastic layer 2 and the second elastic layer 3 are made of elastic material, which can provide excellent shock absorption and rebound effects for the sole of the human foot during running. The heel stabilization component 4 is arranged above the first elastic layer 2, corresponding to the heel position of the human foot.

[0050] like Figure 3 As shown, the second elastic layer 3 includes a forefoot portion 103 , a midfoot portion 203 and a heel portion 301 , which are respectively arranged corresponding to the first area 100 , the second area 200 and the third area 300 of the ejection support member 1 .

[0051] Specifically, a first ejection support portion 104 is provided in the forefoot portion 103 of the second elastic layer 3, corresponding to the first ejection portion 101 of the first area 100 of the ejection support member 1, so as to form an upward support for the first ejection portion 101 and enhance the shock-absorbing rebound performance, providing a pedal spring-like effect for the first ejection portion 101 to eject upward.

[0052] A second ejection support portion 204 is provided at the midfoot portion 203 of the second elastic layer 3, and the second ejection support portion 204 is provided protruding from the upper surface of the second elastic layer 3. The protruding height of the second ejection support portion 204 gradually increases in the direction from the midfoot portion 203 of the second elastic layer 3 toward the heel portion 301, so as to form a slide-like inclined boss. A cavity unit 302 is also formed at one end of the second ejection support portion 204 close to the heel portion 301, and the cavity unit 302 corresponds to the position of the heel portion 301 of the second elastic layer 3.

[0053] Specifically, the second ejection support part 204 located below the second ejection part 201 is made of a highly elastic material, which can not only provide a certain degree of stable support for the second ejection part 201, but also utilize its own highly elastic characteristics to achieve a spring-like rebound effect. The inclined second ejection support part 204 cooperates with the second ejection part 201 and the second shock-absorbing part 202 that are arranged at an angle, and can provide a good ejection assist effect to the human foot in the forward and upward directions, thereby improving athletic performance.

[0054] The cavity unit 302 located on one side of the second ejection support portion 204 can provide a larger deformation space for the second ejection portion 201, especially for the area of the second ejection portion 201 close to the heel portion 301. On the one hand, it can improve the shock absorption and buffering effect, and at the same time enable the ejection assembly to store more ejection energy and enhance the ejection assist effect. The cavity unit 302 is preferably Figure 3 the through structure shown in Figure 3 , that is, a hollow structure is provided at the position of the second elastic layer 3 corresponding to the cavity unit 302, and the cavity unit 302 is communicated with the space below the second elastic layer 3 through the hollow structure. This setting method is not only beautiful in appearance, but also can further increase the deformation space of the second ejection portion 201, while reducing the weight of the sole and improving the movement performance of the sole.

[0055] Of course, in some other embodiments, the cavity unit 302 can also be set to a non-through structure, that is, as long as a cavity is formed below the second ejection portion 201, it can also achieve a certain effect of enhancing the ejection assist effect.

[0056] In order to better understand the purpose, structure and function of the present utility model, the ejection support member, sole and shoe of the present utility model will be further described in detail below with reference to the accompanying drawings, taking the specific structure of the ejection support member 1 as an example.

[0057] Embodiment 1, as shown in Figure 4 and Figure 5 shown, the ejection support member 1 includes a first region 100, a second region 200 and a third region 300. Among them, two linear first dividing grooves are provided on the first region 100, and the first dividing grooves are respectively arranged on both sides of the middle line inside and outside the first region 100, and both are shot from one end of the first region 100 close to the heel to the other end in the direction of the toe of the first region 100, thereby forming a front fork structure in the middle of the first region 100.

[0058] Specifically, the first region 100 includes a first ejection portion 101 provided in the middle and first shock absorption portions 102 provided on both sides of the first ejection portion 101. One end of the first ejection portion 101 close to the toe portion is tilted upward in the vertical direction, so that the first ejection portion 101 is integrally inclined and a ejection space is formed between the first ejection portion 101 and the first shock absorption portion 102.

[0059] When the front sole of the human foot steps on the sole of the shoe during exercise, the first elastic part 101 is stressed. At this time, the first elastic part 101 presses downward towards the first shock-absorbing part 102, compressing the elastic space, providing shock absorption and buffering effects for the human foot, and storing energy. The shock-absorbing part is located below both sides of the first elastic part 101 and is used to improve the running rolling effect. At the same time, it works together with the first elastic part 101 to achieve the shock-absorbing function. When the human foot is lifted, the first elastic part 101 restores its shape under the elastic action, releases the stored energy, and provides an upward and forward rebound and boosting effect for the human foot.

[0060] Further, in the lateral direction, the width of the first elastic part 101 is greater than the width of the first shock-absorbing part 102. Specifically, the first elastic part 101 corresponds to the second and third metatarsal bones of the human foot. The first shock-absorbing part 102 is arranged on the inner and outer sides of the first area 100. The inner first shock-absorbing part 102 corresponds to the first metatarsal bone of the human foot, and the outer first shock-absorbing part 102 corresponds to the fourth and fifth metatarsal bones of the human foot. In the longitudinal direction, the length of the first elastic part 101 is less than that of the first shock-absorbing part 102. Specifically, the inner first shock-absorbing part 102 corresponds to the first toe of the foot, the outer first shock-absorbing part 102 corresponds to the fourth and fifth toes of the foot, while the first elastic part 101 does not correspond to the second and third toes of the foot, so that the middle area of the first area 100 near the toe tip is hollowed out, thereby.

[0061] The above setting method can conform to the force characteristics of the human running exercise during the extension stage. On the one hand, it can provide support and propulsion for the second and third metatarsal bone areas, facilitating better forceful extension and improving sports performance. On the other hand, it can better disperse the large stress generated in the second and third toe areas, reducing the impact pressure on the second and third toes when stepping on the sole of the shoe.

[0062] In addition, it also includes a second dividing groove provided at the second area 200 and the third area 300 of the above-mentioned elastic support member 1. This second dividing groove divides the second area 200 and the third area 300 of the support member into a second elastic part 201 and a second shock-absorbing part 202.

[0063] Further, the first area 100, the second area 200, and the third area 300 of the elastic support member 1 are of an integrally formed structure to enhance the overall stability and support effect of the elastic support member 1.

[0064] The upper and lower parts of the sole containing the elastic support member 1 are respectively provided with a first elastic layer 2 and a second elastic layer 3. Among them, a first elastic support part 104 is provided at the front sole part 103 of the second elastic layer 3, corresponding to the first elastic part 101 of the first area 100 of the elastic support member 1, to form an upward support for the first elastic part 101, enhance the shock absorption and rebound performance, and provide an effect similar to a pedal spring for the upward ejection of the first elastic part 101.

[0065] Specifically, a first ejection support portion 104 is provided at the forefoot portion 103 of the second elastic layer 3, and the first ejection support portion 104 protrudes from the upper surface of the second elastic layer 3. The protruding height of the first ejection support portion 104 gradually increases in the direction towards the toe portion at one end of the forefoot portion 103 of the second elastic layer 3 away from the toe, so as to form a slide-shaped inclined boss.

[0066] The first ejection support portion 104 is located below the first ejection portion 101, which can not only play a certain role in stably supporting the first ejection portion 101, but also utilize its own elastic characteristics to play a shock-absorbing and rebounding effect similar to that of a spring, and can provide a good ejection boost effect on the human foot in the forward and upward directions, thereby improving sports performance.

[0067] As Figure 6 shown, the first elastic layer 2 includes a front sole 105, a midsole 205, a rear sole 303, a protection structure 106, and support columns 304. The front sole 105, the midsole 205, and the rear sole 303 respectively correspond to the first area 100, the second area 200, and the third area 300 of the ejection support member 1.

[0068] Specifically, the sidewall protection structure 106 extends upward from the inner and outer sides of the first elastic layer 2, thereby limiting the lateral movement of the human foot and preventing the inversion and eversion of the foot when landing, effectively preventing the inversion and eversion phenomenon of the runner at the moment of landing. The midsole 205 of the first elastic layer 2 provides shock absorption and rebound during running. The support columns 304 are arranged downward along the inner and outer sides of the rear sole 303, close to both sides of the end of the second ejection portion 201 near the heel, thereby assisting in enhancing the support performance of the shoe heel.

[0069] In addition, a second ejection support portion 204 is provided at the midfoot portion 203 of the second elastic layer 3 as described above. The cavity unit 302 located on one side of the second ejection support portion 204 can provide a larger deformation space for the second ejection portion 201, especially for the area of the second ejection portion 201 near the heel portion 301, which can enhance the shock absorption and buffering effect on the one hand.

[0070] Finally, the outsole 5 of the shoe sole is provided corresponding to the bottom of the second elastic layer 3, which can play an anti-wear and anti-slip effect.

[0071] As Figure 7 shown in the second embodiment of the ejection support member 1 in the present utility model, what is the same as the first embodiment is that the ejection support frame includes a second ejection portion 201 and a second shock absorption portion 202, the shoe sole includes a first elastic layer 2, a second elastic layer 3, the midfoot and heel portions 301, an outsole 5, and a heel stabilization assembly 4.

[0072] AsFigures 8 to 10 As shown, different from the first embodiment, a dividing groove is provided in the middle of the first region 100 of the ejection support member 1. The dividing groove is a U-shaped structure with an opening facing the heel direction, thereby forming a backward bifurcated structure at the middle of the first region 100.

[0073] Specifically, the first region 100 includes a first ejection portion 101 provided in the middle, and a semi-circular first shock absorption portion 102. The first shock absorption portion 102 is located on the inner and outer sides of the forefoot and the outer edge of the toe tip, surrounding the outside of the first ejection portion 101. One end of the first ejection portion 101 close to the heel portion 301 is upturned in the vertical direction, so that the first shock absorption portion 102 is integrally inclined and forms an ejection space with the first ejection portion 101.

[0074] During exercise, when the forefoot of the human foot steps on the sole of the shoe, the first ejection portion 101 is stressed. At this time, the first ejection portion 101 presses downward toward the first shock absorption portion 102, compressing the ejection space, providing shock absorption and buffering effects for the human foot, and storing energy. The shock absorption portion is located below the inner and outer sides and the front side of the first ejection portion 101, used to improve the running rolling effect, and at the same time cooperate with the first ejection portion 101 to achieve the shock absorption function. When the human foot is lifted, the first ejection portion 101 restores its shape under the elastic action, releases the stored energy, and provides an upward and forward rebound and boost effect for the human foot.

[0075] Furthermore, in the transverse direction, the width of the first ejection portion 101 is greater than the width of the first shock absorption portion 102. Specifically, the first ejection portion 101 corresponds to the second and third metatarsal bones of the human foot. The first shock absorption portion 102 is provided on the inner and outer sides of the first region 100. The inner first shock absorption portion 102 corresponds to the first metatarsal bone of the human foot, and the outer first shock absorption portion 102 corresponds to the fourth and fifth metatarsal bones of the human foot. The front first shock absorption portion 102 corresponds to the second and third phalanges of the human foot, so as to provide support for the force application points of the middle metatarsal bones of the forefoot corresponding to the pushing-off stage.

[0076] The above setting method can conform to the force application characteristics of the pushing-off stage of human running motion. On the one hand, it can provide support and propulsion for the second and third metatarsal regions, facilitating better pushing-off force application and improving sports performance. On the other hand, it can better disperse the relatively large stress generated in the second and third toe regions, reducing the impact pressure on the second and third toes when stepping on the sole of the shoe.

[0077] Furthermore, as Figure 11As shown in the figure, a first ejection support part 104 is provided at the forefoot part 103 of the second elastic layer 3, corresponding to the first ejection part 101 of the first area 100 of the ejection support member 1, so as to form an upward support for the first ejection part 101 and enhance the shock absorption and resilience performance, providing an effect similar to that of a pedal spring for the upward ejection of the first ejection part 101.

[0078] Specifically, a first ejection support part 104 is provided at the forefoot part 103 of the second elastic layer 3, and the first ejection support part 104 protrudes from the upper surface of the second elastic layer 3. The protruding height of the first ejection support part 104 gradually increases in the direction from the end of the forefoot part 103 of the second elastic layer 3 close to the toe towards the end close to the heel, so as to form a slide-shaped inclined boss.

[0079] The first ejection support part 104 is located below the first ejection part 101, which can not only play a certain stable support role for the first ejection part 101, but also utilize its own elastic characteristics to play a shock absorption and resilience effect similar to that of a spring, and can provide a good ejection assistance effect for the human foot in the forward and upward directions, thereby improving the sports performance.

[0080] As Figure 12 shown in the third embodiment of the ejection support member 1 in the present utility model, which is the same as the first embodiment, the ejection support frame includes a second ejection part 201 and a second shock absorption part 202, the sole includes a first elastic layer 2, a second elastic layer 3, the midfoot and heel parts 301, an outsole 5, and a heel stability component 4.

[0081] As Figures 13 to 15 shown, different from the first embodiment, the first area 100 of the ejection support member 1 includes a first shock absorption part 102 recessed in the middle position and first ejection parts 101 protruding on both sides of the first shock absorption part 102, that is, the first shock absorption part 102 is connected to the first ejection parts 101 at the end close to the toe and is disconnected and extended in the direction pointing to the heel, and the first ejection parts 101 arch towards the direction where the human foot is located, forming an ejection space with the first shock absorption part 102.

[0082] When the forefoot of the human foot steps on the sole during exercise, the first ejection part 101 is stressed. At this time, the first ejection part 101 presses down towards the first shock absorption part 102, compressing the ejection space, providing a shock absorption and buffering effect for the human foot and storing energy. The shock absorption part is located below the middle of the first ejection part 101, which is used to improve the running rolling effect and, together with the first ejection part 101, realizes the shock absorption function. When the human foot is lifted, the first ejection part 101 restores its shape under the elastic action, releasing the stored energy and providing an upward and forward rebound and boost effect for the human foot.

[0083] Specifically, the first ejection portion 101 located on the inner side of the first area 100 is arranged corresponding to the first metatarsal bone of the human foot, the first ejection portion 101 located on the outer side of the first area 100 is arranged corresponding to the fourth and fifth metatarsal bones of the human foot, and the first shock absorbing portion 102 of the first area 100 is arranged corresponding to the second and third metatarsal bones of the human foot.

[0084] The above-mentioned setting method can conform to the force characteristics of the human body in the kicking and stretching phase of running. On the one hand, it can provide support and propulsion to the first, fourth and fifth metatarsal regions, facilitating better kicking and stretching and improving athletic performance. On the other hand, it can better disperse the greater stress generated in the second and third metatarsal regions, reduce impact and improve the cushioning effect.

[0085] Further, if Figure 16 As shown, the forefoot portion 103 of the second elastic layer 3 is provided with two upwardly arched forefoot protrusions 107, and the forefoot protrusions 107 are respectively located on the inner and outer sides of the forefoot portion 103 of the second elastic layer 3, corresponding to the ejection space formed by the ejection support member 1, and a concave structure 108 is provided on the top of the forefoot protrusion 107, and the arc surface of the concave structure 108 and the bottom surface of the first ejection portion 101 form a transverse hollow structure.

[0086] Specifically, the first ejection part 101 is placed above the forefoot bump 107 and is suspended in the middle to form a three-dimensional hollow structure. The hollow structure can undergo elastic deformation during pedaling, and use its own elastic characteristics to achieve a shock-absorbing and rebound effect similar to that of a spring. At the same time, it stores energy and then releases it again, providing strong propulsion for the extension phase, thereby improving athletic performance.

[0087] The first elastic layer 2 and the second elastic layer 3 described above can be made of one, two or more materials selected from nylon elastomer, thermoplastic polyurethane (including aromatic and aliphatic types), cast polyurethane, mixed polyurethane, thermoplastic polyether ester elastomer, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene-styrene block copolymer, hydrogenated styrene-butadiene-styrene block copolymer, polyisobutylene, high styrene rubber, brominated butyl rubber, butadiene rubber, silicone rubber, EPDM rubber, natural rubber, isoprene rubber, nitrile rubber, and chloroprene rubber, and are prepared by supercritical foaming or chemical foaming. Preferably, the supercritical bead foaming material (one selected from nylon elastomer, thermoplastic polyurethane, and polyether ester elastomer) is used, and the material characteristics are hardness (Asker C) 42±6, density 0.10-0.18g / cm 3 , rebound 75%-85%, shock absorption (Peak G) 6-12. The material is light, soft and elastic, and can provide excellent shock absorption and rebound effects for the midfoot part 203 to the forefoot part 103 of the human foot during running.

[0088] A rigid support plate, characterized in that it has a Shore D hardness of 50-95 and is a support plate made of a rigid material, such as epoxy resin, phenolic resin or thermoplastic resin (thermoplastic polyurethane, polycarbonate, polymethyl methacrylate, nylon elastomer, polyether ester elastomer, polyketone, polyether ether ketone, polyether ketone ketone, polyethersulfone, polyphenylene sulfide, ABS (acrylonitrile-butadiene-styrene copolymer) and its composites formed with inorganic fillers or long fibers or short fibers. Preferably, it is a composite material of epoxy resin and carbon fiber, with a thickness of 0.8-3.0 mm.

[0089] The present utility model also discloses a shoe, including a sole containing any one of the above-mentioned ejection support members 1.

[0090] As shown in the following table, in order to verify the performance of the ejection support member 1 and the sole and shoe containing the ejection support member 1 in the present utility model, Figure 17 the racing running shoes shown in [reference] are selected as the comparative test sample shoes, and are compared with the ejection support member 1 and the shoes containing the support member of the present utility model. The comparative test sample shoes have a sole structure with a flat support plate embedded between the upper and lower midsoles 205. The following is the performance comparison of the finished shoes:

[0091]

[0092] In the above table, the peak acceleration represents the shock absorption performance, and the smaller the value, the better the shock absorption performance; the energy return represents the resilience, and the larger the value, the better the resilience performance. It can be seen from the data in the table that compared with the comparative examples, the shock absorption and resilience of each embodiment have been significantly improved to varying degrees.

[0093] The ejection support member 1, the sole and the shoe of the present utility model can provide good ejection assistance for the forefoot and heel of the human foot, and at the same time have excellent resilience and shock absorption, which can significantly improve the sports performance of the wearer. The forefoot and heel parts 301 of the ejection sole have good stability and support, which can prevent the wearer from suffering sports injuries. Moreover, the forefoot part 103 of the ejection sole has good bending performance, which can improve the wearing comfort of the sole and facilitate the rapid rebound of the support plate. At the same time, the weight of the sole is also greatly reduced.
