Description

Technical Field

[0001] The invention belongs to the technical field of footwear products, and in particular relates to a racing shoe specifically for women. Background Art

[0002] There are many racing shoes in life. Whether it is men's sports shoes or women's sports shoes, the styles of the soles are usually consistent, including the heel structure of the soles. However, the human body functions of female racers are different from those of male racers. For example, women's calf muscles are far less developed than men's, and they cannot run on the forefoot for a long time. When the back foot lands, the soles of women's shoes usually need stronger support than men's. Similarly, women's racing shoes also require better shock absorption, so that the heel will not be tired when landing.

[0003] Currently on the market, due to the lack of heel wrapping performance, the support, comfort and shock absorption performance of shoes need to be further improved.

[0004] In view of this, the inventor of this case conducted in-depth research, which resulted in the creation of this case. Summary of the invention

[0005] The object of the present invention is to provide a shoe support plate which has better shock absorption and supporting effects on the heel.

[0006] The purpose of the present invention is to provide a sole with better heel shock absorption and supporting effects.

[0007] The purpose of the present invention is to provide a racing shoe for women with better heel shock absorption and supporting effects.

[0008] In order to achieve the above object, the technical solution of the present invention is: 14. The shoe support plate as claimed in claim 13, wherein the shoe support plate is a rigid plate with elasticity, the shoe support plate comprising a forefoot portion, an arch portion and a heel portion, the arch portion being located between the forefoot portion and the heel portion, the heel portion having a three-dimensional split structure, the three-dimensional split structure comprising a downward-turned elastic support strip, and a first support strip and a second support strip located on both sides of the downward-turned elastic support strip, a first groove being formed between the first support strip and the downward-turned elastic support strip, a second groove being formed between the second support strip and the downward-turned elastic support strip, the ends of the downward-turned elastic support strip, the first support strip and the second support strip being all free ends, the downward-turned elastic support strip being arranged downwardly, the free end of the downward-turned elastic support strip being located below the supporting surface where the shoe support plate is located, an acute angle being formed between the downward-turned elastic support strip and the supporting surface where the shoe support plate is located, and the downward-turned elastic support strip being arranged corresponding to the middle part of the heel of a human body; the first support strip and the second support strip together form a supporting wrapping surface that matches the calcaneal structure of a human body.

[0009] Furthermore, the first support bar and the second support bar are arranged in an inverted eight-shaped shape, the first support bar is located on the outside, the second support bar is located on the inside, and the inclination angle of the first support bar to the horizontal plane is greater than the inclination angle of the second support bar to the horizontal plane; The shoe support plate is a carbon support plate, a nylon support plate or a TPU support plate.

[0010] Furthermore, the arch portion is provided with inner reinforcing ribs and outer reinforcing ribs, the inner reinforcing ribs are arranged corresponding to the direction of the inner longitudinal arch of the human body; the outer reinforcing ribs are arranged corresponding to the direction of the outer longitudinal arch of the human body.

[0011] Furthermore, an inner side of the arch portion is extended to form an inner side arch support portion, and the inner side arch support portion fits with the inner longitudinal arch of the human body.

[0012] Furthermore, the forefoot portion has a wave-shaped support portion, and the wave-shaped support portion is arranged at the middle palm position or the middle forefoot position of the forefoot portion. The wave-shaped support portion is extended in a concave and convex manner along the length direction of the shoe support plate. The wave-shaped support portion is wavy, and the lateral direction of the wave of the wave-shaped support portion is consistent with the arrangement direction of the toe bones. Furthermore, the forefoot portion includes the wave-shaped support portion, and a palm front support portion located at the front end of the wave-shaped support portion, the front end portion of the wave-shaped support portion is a wave-shaped recessed portion, the front end of the wave-shaped support portion is formed with a front edge that is tilted upward and forward, the palm front support portion is tilted upward, the palm front support portion is smoothly connected with the front edge of the wave-shaped support portion, and the tilting angle of the palm front support portion is smoothly transitioned with the tilting angle of the front edge of the wave-shaped support portion Furthermore, a hollow hole is opened in the middle part of the forefoot portion, and the forefoot portion forms a U-shaped structure around the hollow hole. The wave-shaped support portion forms a first wave-shaped support portion and a second wave-shaped support portion on both sides of the hollow hole. The first wave-shaped support portion, the hollow hole and the second wave-shaped support portion are arranged in sequence along the width direction of the shoe support plate, and the first wave-shaped support portion and the second wave-shaped support portion are respectively part of the U-shaped structure.

[0013] Furthermore, the forefoot portion is provided with a support tongue in the hollow hole, one end of the support tongue is connected to the arch portion, and the other end of the support tongue is a free end. The present invention discloses a support plate for shoes, which is provided with a three-dimensional split structure, and the downward-turned elastic support strip is turned downward, so as to provide rebound energy for the support plate to bend and feedback when the middle and rear heels touch the ground, and at the same time play the function of stable support. Due to the downward-turned design, compared with the first support strip and the second support strip, the downward-turned elastic support strip is squeezed and deformed to a greater extent when the heel touches the ground, and the rebound force generated is also greater. The rigid plate is adopted, which has a greater hardness, and the instantaneous elasticity generated is also greater, the speed is faster, the rebound force is greater, and the support stability is better. The first support strip and the second support strip are located on both sides of the upward-turned elastic support strip. When the upward-turned elastic support strip generates a large rebound, the first support strip and the second support strip can wrap the heel adaptively. The first support strip and the second support strip are relatively independent, have different rebound forces, good adaptability, and good wrapping of the heel.

[0014] Furthermore, the first support strip and the second support strip are arranged in an inverted eight shape, which can form a concave surface that fits the heel and has good wrapping performance. The heel wrapping design of the present invention (cooperation of the first support strip and the second support strip) can improve comfort and shock absorption performance.

[0015] Furthermore, since the female pelvis is wider than the male pelvis, the Q angle will also be larger. Studies have shown that a larger Q angle will lead to changes in the biomechanical structure of the lower limbs, making the female knee joint face a greater risk of valgus in both static and dynamic conditions. The first support bar of the present invention is located on the outside, with a larger inclination angle, and the outside support is stronger than the inside support, which can effectively prevent valgus. Furthermore, the provision of internal and external reinforcing ribs can enhance the upward curvature of the midfoot arch, which is more conducive to female runners being able to effectively and quickly support the instep of the foot when running in the mid-forefoot and full-palm methods, thereby reducing the time loss in the forward and backward transition.

[0016] Furthermore, the hollow holes can disperse the pressure and appropriately reduce the rigidity of the support plate, making it easier to push the shoe forward according to its rolling motion. The U-shaped structure still provides good support for the forefoot.

[0017] Furthermore, a support tongue is provided, and the peripheral side of the support tongue (except the connection part with the arch part) is a hollow area, which can maintain the flexibility of the support plate and further improve the support rigidity and rolling transmission of the wave-shaped support part. It helps the rolling force of the sole, the rolling feeling is stronger, and running is more labor-saving, easy and comfortable.

[0018] Furthermore, the first wave-shaped support part and the second wave-shaped support part can react independently, better disperse the weight applied by the foot and reduce pressure points. The ergonomic design is adopted, and the first wave-shaped support part and the second wave-shaped support part are designed independently in different areas, which can adaptively and evenly support various parts of the foot and relax the foot muscles.

[0019] Furthermore, the forefoot portion has a higher tilt angle than conventional shoes on the market. In this way, during exercise, a continuous rolling thrust is formed, which increases the rolling property of the forefoot and reduces time consumption. Compared with the traditional running method of hard force and steps, the rolling thrust of the present invention makes running more labor-saving and more comfortable. As female runners mostly use the step frequency method, the method of increasing the tilt angle of the present invention can increase the rolling property of the forefoot and reduce time consumption.

[0020] A shoe sole, comprising a foam sole, an anti-skid sole, and a shoe support plate as claimed in any one of claims 1 to 7, wherein the shoe support plate is coated inside the foam sole, the anti-skid sole is fixed to the bottom surface of the foam sole, and the drop of the shoe sole along the keel line direction is 8 to 10 mm; The foam bottom is provided with a foam bottom hollow area corresponding to the wave-shaped support part and the arch part, and the corresponding bottom surface of the shoe support plate is exposed in the foam bottom hollow area; The anti-slip bottom has an anti-slip bottom hollow area corresponding to the foam bottom hollow area, and the anti-slip bottom hollow area extends along the keel line of the sole, extending from the position corresponding to the arch part to the position corresponding to the wave-shaped support part and the arch part.

[0021] After adopting the above scheme, a sole of the present invention increases the keel drop (the keel drop of ordinary racing shoes is about 5mm), which is more in line with the labor-saving structural characteristics of women. It is an adjustment conclusion that is comprehensively drawn based on relevant research on the running posture and physiological structure of female runners and the differences from men, and is obtained through actual experiments. In addition, the hollow area of ​​the foaming bottom and the hollow area of ​​the anti-slip bottom are respectively set to greatly enhance the shock-absorbing function of the sole, release the pressure on the sole of the foot in the force-bearing area during exercise, and run easily. (The peak acceleration of the heel of the laboratory mechanical test data can be 8.3g, which is significantly better than conventional racing shoes) A racing shoe specially for women comprises a shoe upper and a shoe sole, wherein the shoe sole adopts the above-mentioned shoe sole.

[0022] After adopting the above technical solution, the present invention provides a racing shoe for women, which is provided with a three-dimensional split structure, and provides better support, shock absorption and stability for the heel. A shoe support plate is provided to improve the rigidity of the sole, improve the shock absorption, improve the heel difference (keel drop) of the sole, and make the transition of the shoe better. The hollow hole is provided, and the rigidity of the support plate is appropriately reduced. Combined with the wave-shaped support part, the forefoot is upturned, etc., it is conducive to the rolling force of the shoe to push forward, making the shoe more comfortable during exercise.

DETAILED DESCRIPTION

[0025] The front, back, top, bottom and other directions of the present invention are based on the directions of the shoes in a normal use state.

[0026] The present invention discloses a racing shoe for women, comprising a shoe upper and a shoe sole connected together. Figure 1 and Figure 3 As shown, the shoe support plate 1 includes a shoe support plate 1, a foam bottom 2 and an anti-skid bottom 3. The shoe support plate 1 is coated inside the foam bottom 2. During processing, the shoe support plate 1 is placed at a set position of a foaming mold of the foam bottom 2, and then the foaming operation of the foam bottom 2 is performed. In the present invention, the position of the shoe support plate 1 relative to the inside of the foam bottom 2 can be set according to actual needs. In this embodiment, the shoe support plate 1 is set at the middle layer position in the thickness direction of the foam bottom 2. The anti-skid bottom 3 is fixed to the bottom surface of the foam bottom 2.

[0027] In the present invention, the front and rear keel drop of the female-specific racing shoes is 8-10 mm. Compared with the conventional keel drop of about 5 mm, the female-specific racing shoes of the present invention increase the keel drop, so that during the high-frequency repeated bending of the forefoot (foot lifting and falling), the transition of the female-specific racing shoes is smoother and the running is more efficient.

[0028] In the present invention, the shoe support plate 1 is a rigid plate. The rigid plate is a plate that can increase the rigidity of the sole. The hardness of the shoe support plate 1 is usually harder than the foam sole 2. The shoe support plate 1 can be a carbon support plate, a nylon support plate or a TPU support plate, etc., as long as it can better increase the rigidity of the sole.

[0029] In this embodiment, the shoe support plate 1 is described as a carbon plate. Figure 2As shown, the shoe support plate 1 includes a forefoot portion 11, an arch portion 12 and a heel portion 13. The forefoot portion 11 is arranged corresponding to the forefoot of a human foot, the arch portion 12 is arranged corresponding to the arch of a human foot, and the heel portion 13 is arranged corresponding to the heel of a human foot. The arch portion 12 is located between the forefoot portion 11 and the heel portion 13.

[0030] The heel portion 13 has a three-dimensional split structure, which includes a downward-turned elastic support bar 131, and a first support bar 132 and a second support bar 133 located on both sides of the downward-turned elastic support bar 131, a first groove 134 is formed between the first support bar 132 and the downward-turned elastic support bar 131, and a second groove 135 is formed between the second support bar 133 and the downward-turned elastic support bar 131, the ends of the downward-turned elastic support bar 131, the first support bar 132 and the second support bar 133 are all free ends, the downward-turned elastic support bar 131 is turned downward, and the free end of the downward-turned elastic support bar 131 is located below the support surface where the shoe support plate 1 is located, and an acute angle is formed between the downward-turned elastic support bar 131 and the support surface where the shoe support plate 1 is located, and the downward-turned elastic support bar 131 is arranged corresponding to the middle part of the human heel; the first support bar 132 and the second support bar 133 are arranged in an inverted eight-shaped shape to form a support wrapping surface that fits the human calcaneal structure.

[0031] The first support bar 132 is located on the outside, and the second support bar 133 is located on the inside. The first support bar 132 is inclined at a greater angle to the horizontal plane than the second support bar 133. Preferably, the free end of the downwardly turned elastic support bar 131 is formed with a straight section 1311, so that rebound can be achieved more smoothly, and repeated pedaling is also convenient.

[0032] The forefoot portion 11 has a wave-shaped support portion 4, which is arranged at the middle of the forefoot portion 11 (i.e., the middle of the forefoot), and the wave-shaped support portion 4 is arranged to extend in a concave-convex manner along the length direction of the shoe support plate 1, and is wave-shaped. Figure 1As shown, the shoe support plate 1 forms a first concavoconvex curved surface 41 on the top surface of the wave-shaped support portion 4, and the first concavoconvex curved surface 41 is a part of the top surface of the shoe support plate 1; the shoe support 1 forms a second concavoconvex curved surface 42 on the bottom surface of the wave-shaped support portion 4, and the second concavoconvex curved surface 42 is a part of the bottom surface of the shoe support plate 1. The convex surface of the first concavoconvex curved surface 41 corresponds to the convex surface of the second concavoconvex curved surface 42, and the concave surface of the first concavoconvex curved surface 41 corresponds to the concave surface of the second concavoconvex curved surface 42. The spacing between the first concavoconvex curved surface 41 and the second concavoconvex curved surface 42 is uniform. The thickness between the first concavoconvex curved surface 41 and the second concavoconvex curved surface 42 is the plate thickness of the shoe support plate 1. The local thickness of the shoe support plate 1 is uniform. The highest point of the convex surface of the second concavoconvex curved surface 42 is higher than the height of the overall support surface of the shoe support plate 1, and the lowest point of the concave surface of the first concavoconvex curved surface 41 is lower than the height of the overall support surface of the shoe support 1. In this embodiment, the wavy transverse direction of the wavy support part 4 is consistent with the arrangement direction of the toe bones. Compared with the width direction of the sole, the arrangement direction of the metatarsal bones is inclined, and when the forefoot moves and bends, the force line of the forefoot is also inclined. By setting the wavy transverse direction of the wavy support part 4 to be consistent with the arrangement direction of the toe bones, the force line of the human body running is more matched, making the force transmission smoother.

[0033] In the present invention, the wave-shaped support portion 4 may also extend from the middle palm position of the forepalm portion 11 to the middle forepalm position. The location of the wave-shaped support portion 4 may be set according to actual conditions.

[0034] The present invention discloses a shoe support plate 1, which adopts a corrugated carbon plate. When the corrugated support part 4 is subjected to downward pressure applied by the foot, according to the force of the wave surface, the corrugated support part 4 can not only be pushed forward, but also extend and expand along the longitudinal direction (and the length direction of the shoe) when the foot steps on the pedal, and undergoes a certain deformation. When the foot is lifted, the deformed corrugated support part 4 will rebound and generate an upward rebound force. In this way, the corrugated support part 4 can generate a double force structure, forming a good forward and upward boost force for the foot. The shoe support plate 1 not only has good support, but also can form a good boost force when used, making exercise more labor-saving and more comfortable. At the same time, the concave and convex surface of the corrugated support part 4 has a certain indirect massage effect on the foot. This makes the foot more comfortable during exercise and minimizes the soreness of the foot.

[0035] As a preferred implementation mode, Figure 1As shown, the forefoot portion 11 includes a wave-shaped support portion 4, and a palm front support portion 112 located at the front end of the wave-shaped support portion 4. The palm front support portion 112 is tilted forward. Specifically, the front end portion of the wave-shaped support portion 4 is a wave depression, that is, the front end portion of the wave-shaped support portion 4 is depressed downward, forming a front edge 43 tilted upward and forward. The palm front support portion 112 is smoothly connected with the front edge 43 of the wave-shaped support portion 4. The upward tilt angle of the palm front support portion 112 and the upward tilt angle of the front edge 43 of the wave-shaped support portion 4 are smoothly transitioned. The forefoot of the forefoot of the forefoot portion 11 is higher than that of conventional shoes on the market. In this way, during the exercise, a continuous rolling thrust will be formed. Compared with the traditional running method of hard force relying on steps, the rolling thrust of the present invention makes running more labor-saving and more comfortable.

[0036] As a preferred implementation method, Figure 2 and Figure 3 As shown, a hollow hole 111 is provided in the middle of the forefoot portion 11, and the forefoot portion 11 forms a U-shaped structure around the hollow hole 111. In this way, the U-shaped structure still provides good support for the forefoot of the foot, and the hollow hole 111 can disperse the pressure. The rigidity of the carbon plate is appropriately reduced. It is convenient to push forward according to the rolling of the shoe. The carbon plate structure is more flexible, avoids rigidity, and further improves comfort.

[0037] Specifically, Figure 2 As shown, the wave-shaped support part 41 is formed with a first wave-shaped support part 41 and a second wave-shaped support part 42 on both sides of the hollow hole 111. The first wave-shaped support part 41 and the second wave-shaped support part 42 are respectively part of the above-mentioned U-shaped structure. The first wave-shaped support part 41, the hollow hole 111 and the second wave-shaped support part 42 are arranged in sequence along the width direction of the shoe support plate 1. In this way, the hollow hole 111 can cut off the transmission of force between the first wave-shaped support part 41 and the second wave-shaped support part 42 in the width direction of the sole support plate 1. The first wave-shaped support part 41 and the second wave-shaped support part 42 can react independently, better disperse the weight applied by the foot, and reduce pressure points. In accordance with ergonomic design, the first wave-shaped support part 41 and the second wave-shaped support part 42 are independently designed in different areas, which can adaptively and evenly support various parts of the foot and relax the foot muscles. At the same time, the U-shaped structure can ensure the overall support of the forefoot part 1. To a certain extent, force can be transmitted in both the width direction and the length direction.

[0038] Furthermore, if Figure 2 and Figure 3As shown, the forefoot portion 11 is provided with a support tongue 113 in the hollow hole 111. The rear end of the support tongue 113 is connected to the arch portion 12, and the front end is a free end. The support tongue 113 can further improve the support rigidity and rolling transmission of the wave-shaped support portion 4. It helps the rolling force of the sole, the rolling feeling is stronger, and running is more labor-saving, easy and comfortable.

[0039] As a preferred embodiment, the arch portion 12 is provided with an inner reinforcing rib 121 and an outer reinforcing rib 122. The inner reinforcing rib 121 is arranged in the direction corresponding to the inner longitudinal arch of the human body, and is protruding downward from the bottom surface of the arch portion 12; the outer reinforcing rib 122 is arranged in the direction corresponding to the outer longitudinal arch of the human body, and is protruding downward from the bottom surface of the arch portion 12. In this way, better arch support can be provided.

[0040] Furthermore, the inner side of the arch portion 12 extends along the width direction of the sole to form an inner arch support portion 123, which fits with the inner longitudinal arch of the human body to strengthen the inner arch support, thereby enabling the entire arch to be stably supported.

[0041] The female-specific racing shoes of the present invention are provided with a shoe support plate 1 to improve the rigidity of the sole, provide better shock absorption, improve the heel difference (keel drop) of the sole, and make the transition of the shoe better. A hollow hole 111 is provided to appropriately reduce the rigidity of the carbon plate. Combined with the wave-shaped support part 4 and the forefoot upturned design, the shoe is conducive to rolling and pushing forward, making the shoe more comfortable during exercise. Table 1 below is the comparative test data of the sole of the female-specific racing shoes of the present invention. The front and rear keel drop of the female-specific racing shoes in Table 1 below is 8-10 mm, and the keel drop of the ordinary racing shoes is about 5 mm.

[0042] Table 1 below is the comparative test data of the sole of the female-specific racing shoe of the present invention

[0043] It can be seen from Table 1 above that the peak acceleration (mean) of the forefoot and heel of the sole of the present invention is significantly better than that of ordinary racing shoes on the market, and the resilience is also better.

[0044] The peak acceleration of the heel of the present invention can also be as low as 8.3g.

[0045] It should be noted that the shoe support plate of the present invention can have hollow areas in non-stress areas to reduce weight and reduce the load. The specific hollow positions can be set according to actual needs, such as correspondingly set between each toe, or around the toes, etc.

[0046] As a preferred implementation mode, refer to Figure 2As shown, the foam bottom 2 is provided with a foam bottom hollow area 21 corresponding to the wave-shaped support portion 4 and the arch portion 12, and the corresponding bottom surface of the shoe support plate 1 is exposed in the foam bottom hollow area 21; The anti-slip sole 3 is provided with an anti-slip sole hollow area 31 corresponding to the foamed sole hollow area 21. The anti-slip sole hollow area 31 extends along the keel line of the sole (i.e., the length direction of the sole), extending from the position corresponding to the arch portion 12 to the position corresponding to the wave-shaped support portion 4 and the arch portion 12.

[0047] It should be noted that, in the present invention, the hollow area 21 of the foamed bottom and the hollow area 31 of the anti-slip bottom can also be extended to correspond to the heel portion 13, and can be specifically set according to actual needs.

[0048] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made thereto by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
