[0040] In the present application, "carbon fiber prepreg" refers to carbon fiber fabric that has been combined with thermosetting or thermoplastic resin. This material can be cured and shaped under certain conditions (such as temperature and pressure).

[0041] In the prior art, athletes often wear sports shoes provided with cleats 100 in competitive sports to better provide assistance and reduce their energy consumption during the process of "landing-supporting-scraping". Moreover, in order to have the advantages of high strength and small weight, the soles 1 of the sports shoes are mostly made of carbon fiber plates.

[0042] The current way of setting cleats 100 on carbon fiber plates of sports shoes is to first set protrusions on the bottom surface of the carbon fiber plate through injection molding process, and then insert the cleats 100 into the protrusions. Alternatively, a threaded sleeve is fixed in the protrusion, and the cleat 100 is fixed by threads. However, due to the complex stress condition of the foot during competitive sports, the cleat 100 will be subjected to high-intensity force from multiple directions, and the protrusion that fixes the cleat 100 is prone to deformation, damage, tearing and other conditions, thereby causing the cleat 100 to peel off from the carbon fiber plate, greatly reducing the assistance effect of the sports shoes.

[0043] In order to solve the above problems, in the embodiments of the present application, a sole of a competitive sports shoe is introduced.

[0044] AsFigure 1 As shown in the drawings, the shoe sole 1 mainly comprises a shoe spike 100 and a carbon plate 200. The shoe spike 100 is provided with a flange 110 and a pointed protrusion 120. The carbon plate 200 is stacked by a plurality of carbon fiber prepreg sheets 210 to form a layered structure.

[0045] The carbon plate 200 comprises a first prepreg sheet 211 and a second prepreg sheet 212.

[0046] The first prepreg sheet 211 and the second prepreg sheet 212 are respectively located on the upper side and the lower side of the flange 110. And the first prepreg sheet 211 and the second prepreg sheet 212 clasp and fix the flange 110.

[0047] As shown in the drawings, Figures 2 to 5 The pointed protrusion 120 penetrates through the second prepreg sheet 212. And the pointed protrusion 120 protrudes from the bottom surface of the carbon plate 200.

[0048] Further, the shoe spike 100 is made of titanium alloy material, which can improve the wear resistance of the shoe spike 100 and reduce the weight of the shoe sole 1.

[0049] In this embodiment, the carbon plate 200 is provided as a multi-layer structure and the flange 110 of the shoe spike 100 is clamped in the carbon plate 200, and the protruding block for mounting the shoe spike 100 is removed, which can not only reduce the weight, but also simplify the manufacturing process of the shoe sole 1. Through the common laminating and bonding of the flange 110 of the shoe spike 100 by the adjacent two layers of prepreg sheets, the connection strength of the shoe spike 100 and the carbon plate 200 is enhanced, so that the shoe sole 1 can stably provide power during the movement.

[0050] On the basis of the above-mentioned embodiment, another embodiment of the utility model introduces a shoe sole of a racing shoe.

[0051] The second prepreg sheet 212 has a mounting groove 213 recessed to the lower surface thereof, which is used for accommodating the flange 110.

[0052] The center of the mounting groove 213 is provided with a through hole 214, which is used for penetrating the pointed protrusion 120.

[0053] On the basis of the above-mentioned embodiment, another embodiment of the utility model introduces a shoe sole of a racing shoe.

[0054] The flange 110 has a connecting hole 111 penetrating through the plate surface thereof.

[0055] The end of the pointed protrusion 120 is fixedly connected to the center of the flange 110. The connecting hole 111 is located in the region between the end of the pointed protrusion 120 and the edge of the flange 110.

[0056] On the basis of the above-mentioned embodiment, another embodiment of the utility model discloses a sole of racing sports shoes.

[0057] The flange 110 is disc-shaped, and a plurality of connecting holes 111 are uniformly distributed along the circumference of the flange 110.

[0058] Further, the connecting holes 111 are arc-shaped long holes 112 corresponding to a 45° central angle.

[0059] Preferably, three arc-shaped long holes 112 are uniformly distributed along the circumference of the flange 110.

[0060] On the basis of the above-mentioned embodiment, another embodiment of the utility model discloses a sole of racing sports shoes.

[0061] The pointed convex part 120 is arranged along the median line of the flange 110. The end of the pointed convex part 120 connected with the flange 110 is a cylinder, and the free end of the pointed convex part 120 is a cone.

[0062] On the basis of the above-mentioned embodiment, another embodiment of the utility model discloses a sole of racing sports shoes.

[0063] The first prepreg sheet 211 and the second prepreg sheet 212 are arranged in a manner that the carbon fibers are staggered in different directions, and the direction of the carbon fibers in each layer of prepreg sheet can be adjusted to customize the mechanical properties according to specific application requirements, such as increasing the strength or stiffness in a certain direction.

[0064] On the basis of the above-mentioned embodiment, another embodiment of the utility model discloses a sole of racing sports shoes.

[0065] The second prepreg sheet 212 is provided with a plurality of mounting grooves 213, and the cleats 100 are embedded in the mounting grooves 213 one by one. The first prepreg sheet 211 covers the second prepreg sheet 212 and the cleats 100.

By setting the carbon plate 200 in the above shape, the athlete can bounce twice after the foot is supported by the ground, resulting in less energy loss and greater traction. Furthermore, the athlete's explosive power and stride between the two feet during sprinting are improved. At the same time, one end of the cleat 100 is clamped in the carbon plate 200, which can greatly reduce the weight of the sole 1, avoid the cleat 100 from separating from the carbon plate 200, and enhance the grip of the sole 1, providing more stable assistance for the athlete's tread.
