[0002] There are many running enthusiasts in life, and many runners like to run with the forefoot landing first. However, many existing running shoes cannot provide good support and comfort for the forefoot. Usually, the soles with good support are harder and less comfortable, which makes the human foot uncomfortable after running for a long time, while the soles with good comfort are usually softer and less supportive, which makes the human foot sore after running for a long time.

[0003] 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

[0004] The object of the present invention is to provide a shoe support plate which can provide both good support and good comfort.

[0005] The purpose of the present invention is to provide a sole which can provide both good support and good comfort.

[0006] The object of the present invention is to provide a sports shoe which can provide both good support and good comfort.

[0007] In order to achieve the above object, the technical solution of the present invention is: A shoe support plate, the shoe support plate is a rigid plate, the shoe support plate comprises a forefoot portion, an arch portion and a heel portion, the arch portion is located between the forefoot portion and the heel portion, the forefoot portion is provided with a wave-shaped support portion, the wave-shaped support portion is extended in a concave-convex manner along the length direction of the shoe support plate, the wave-shaped support portion is wavy, the wave transverse direction of the wave-shaped support portion extends along the width direction of the shoe support plate or extends along a direction inclined to the width direction of the shoe support plate, and the angle formed by the inclined direction and the width direction of the shoe support plate is less than 45 degrees.

[0008] Further, the wave-shaped support portion is arranged at the middle palm position or the middle fore palm position of the fore palm portion, and the lateral direction of the wave of the wave-shaped support portion is consistent with the arrangement direction of the toe bones; The shoe support plate is a carbon support plate, a nylon support plate or a TPU support plate.

[0009] Furthermore, the forefoot portion includes the wave-shaped support portion, and a front palm 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 recessed portion, the front end of the wave-shaped support portion is formed with a front edge that is tilted upward and forward, the front palm support portion is tilted upward, the front palm support portion is smoothly connected with the front edge of the wave-shaped support portion, and the upward tilt angle of the front palm support portion is smoothly transitioned with the upward tilt angle of the front edge of the wave-shaped support portion.

[0010] 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.

[0011] 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.

[0012] Furthermore, the arch portion is provided with an inner reinforcing rib and an outer reinforcing rib, the inner reinforcing rib is arranged corresponding to the direction of the inner longitudinal arch of the human body, and the inner reinforcing rib is arranged to protrude downward from the bottom surface of the arch portion; the outer reinforcing rib is arranged corresponding to the direction of the outer longitudinal arch of the human body, and the outer reinforcing rib is arranged to protrude downward from the bottom surface of the arch portion.

[0013] 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.

[0014] After adopting the above scheme, a shoe support plate of the present invention is provided with a wave-shaped structure in the force generating area of ​​the inner and outer toe bones. With the wave-shaped structure, when the wave-shaped support part is subjected to downward pressure applied by the foot, according to the force condition of the wave curved surface, the wave-shaped support part 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 force, and a certain deformation occurs. When the foot is lifted, the deformed wave-shaped support part will reset and rebound, generating an upward rebound force, so that the wave-shaped support part can generate a double force structure, forming a better forward and upward boost force for the foot.

[0015] Furthermore, the forefoot portion has a higher upward angle than conventional shoes on the market. Thus, during exercise, a continuous rolling thrust is generated, 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.

[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, 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.

[0018] 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.

[0019] Furthermore, by providing inner and outer reinforcing ribs, the upward curvature of the midfoot arch can be increased, which can effectively and quickly support the instep and reduce the time loss of the front-to-back transition.

DETAILED DESCRIPTION

[0026] 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.

[0027] The invention discloses a sports shoe, comprising a shoe upper and a shoe sole connected together.

[0028] The sole of the present invention is as 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.

[0029] In the present invention, the front and rear keel drop of the sports shoe is 8-10 mm. Compared with the conventional keel drop of about 5 mm, the sports shoe of the present invention increases the keel drop, so that during the high-frequency repeated bending of the forefoot (foot lifting and falling), the transition of the sports shoe is smoother and the running is more efficient.

[0030] 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.

[0031] In this embodiment, the shoe support plate 1 is described as a carbon plate. Figure 2 As 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. 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). The wave-shaped support portion 4 is arranged 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 the present embodiment, the wavy transverse direction of the wavy support portion 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. The wavy transverse direction of the wavy support portion 4 is set to be consistent with the arrangement direction of the toe bones, so that the force line of the human body running is more matched, and the force transmission is smoother. It should be noted that in the present invention, the wavy transverse direction of the wavy support portion 4 is roughly consistent with the arrangement direction of the toe bones. The wavy transverse direction of the wavy support portion 4 is extended along the width direction of the shoe support plate or extended along a direction inclined to the width direction of the shoe support plate, and the angle formed by its inclined direction and the width direction of the shoe support plate is less than 45 degrees, and the further angle can be 15 to 30 degrees.

[0032] 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.

[0033] 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.

[0034] As a preferred implementation mode, Figure 1 As 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] As a preferred implementation mode, refer to Figure 2 As 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.

[0041] 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.

[0042] The sports shoes of the present invention are provided with a shoe support plate 1 to improve the rigidity of the sole, improve shock absorption, increase the heel difference (keel drop) of the sole, and make the transition of the shoe better. The hollow hole 111 is opened, and the rigidity of the carbon plate is appropriately reduced. Combined with the wave-shaped support part 4 and the upturned forefoot and other designs, it is beneficial to the rolling force of the shoe to push it forward, so that the shoe is more comfortable during exercise.

[0043] 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.

[0044] The shoe support plate of the present invention is particularly suitable for racing women's shoes.

[0045] As a preferred embodiment, 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.

[0046] 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.
