Technical Field
[0001] This application relates to the field of athletic shoe technology, and more specifically, to a sole and athletic shoe. Background Technology
[0002] In the field of related technologies, people's requirements for running shoes are constantly increasing, especially in terms of improving cadence and running speed. Traditional running shoes mainly improve wearing comfort and breathability by optimizing upper materials, while using lightweight sole materials to reduce overall weight. Although these running shoes have made some progress in terms of comfort and lightweighting, their effect on improving cadence and running speed is minimal.
[0003] Therefore, how to improve the running performance of wearers while reducing the risk of foot injuries has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a shoe sole that improves the wearer's running performance while reducing the risk of foot injury.
[0005] Another objective of this application is to provide a sports shoe having the aforementioned sole.
[0006] To achieve the above objectives, this application provides the following technical solution:
[0007] A shoe sole includes an upper midsole, a carbon fiber plate layer, and a lower midsole, which are stacked and bonded together from top to bottom, wherein:
[0008] The carbon plate layer is composed of a forefoot section, a midfoot section and a heel section connected in sequence. The forefoot section is concave on the side facing the lower midsole, and the midfoot section protrudes on the side facing the upper midsole.
[0009] The lower midsole has an anti-slip bottom layer on the side away from the carbon plate layer. The anti-slip bottom layer is attached to the lower midsole and has multiple raised points on it to increase grip.
[0010] Optionally, in the above-mentioned sole, the raised point includes a first raised point, a second raised point, and a third raised point. The first raised point is located at the position of the anti-slip bottom layer corresponding to the forefoot section, the second raised point is located at the position of the anti-slip bottom layer corresponding to the midfoot section and the heel section, and the third raised point is located at the position of the anti-slip bottom layer corresponding to the heel section. The heights of the first raised point, the second raised point, and the third raised point decrease sequentially.
[0011] Optionally, in the above-mentioned sole, the height of the first protrusion is 0.25mm to 0.35mm; and / or,
[0012] The height of the second protrusion is 0.15mm to 0.25mm; and / or,
[0013] The height of the third protrusion is 0.10mm to 0.20mm.
[0014] Optionally, in the above-mentioned sole, the front end of the upper midsole covers the outer front end of the lower midsole.
[0015] Optionally, in the above-mentioned sole, the lower midsole includes a flat segment and raised segments located at both ends of the flat segment, and the heel segment is parallel to the flat segment of the lower midsole.
[0016] Optionally, in the aforementioned sole, the anti-slip bottom layer is further provided with multiple ventilation holes of different diameters.
[0017] Optionally, in the above-mentioned sole, the carbon plate layer includes carbon fiber sheets, the thickness of which is 0.8mm to 1.0mm.
[0018] Optionally, in the above-mentioned shoe sole, the upper midsole and the lower midsole are made of TPF material.
[0019] An athletic shoe includes an upper and a sole as described in any of the preceding claims, wherein the upper and the sole are connected by adhesive or stitching.
[0020] Optionally, in the above-mentioned sports shoes, the upper is a woven structure formed by an elastic weaving process, and the material of the upper is a breathable mesh material, which includes one of polyester fiber, nylon or spandex.
[0021] The sole provided in this application consists of an upper midsole, a carbon fiber plate layer, and a lower midsole layer, stacked sequentially from top to bottom. The carbon fiber plate layer is composed of a forefoot section, a midfoot section, and a heel section connected in sequence. The forefoot section is concave on the side facing the lower midsole, while the midfoot section protrudes on the side facing the upper midsole. This not only thickens the upper midsole and improves cushioning but also provides better propulsion for the wearer, thereby increasing stride frequency and running speed. Simultaneously, an anti-slip bottom layer is located on the side of the lower midsole away from the carbon fiber plate layer. This anti-slip bottom layer is attached to the lower midsole and has multiple raised points, which increases the sole's grip, ensuring stability under various road conditions and reducing the risk of foot injury. As can be seen from the above examples, the sole provided in this application, by setting a carbon plate layer, not only thickens the upper midsole and improves the cushioning effect, but also provides better propulsion for the wearer, thereby achieving the effect of increasing stride frequency and running speed, and improving the wearer's running performance. At the same time, the multiple raised points set on the anti-slip bottom layer can increase the grip of the sole, ensure stability under various road conditions, and reduce the risk of foot injury.

[0037] The core of this application is to provide a shoe sole that improves the wearer's running performance while reducing the risk of foot injury.
[0038] Another key aspect of this application is to provide a sports shoe with the aforementioned sole.
[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0040] In the field of related technologies, people's requirements for running shoes are constantly increasing, especially in terms of improving cadence and running speed. Traditional running shoes mainly improve wearing comfort and breathability by optimizing upper materials, while using lightweight sole materials to reduce overall weight. Although these running shoes have made some progress in terms of comfort and lightweighting, their effect on improving cadence and running speed is minimal.
[0041] Therefore, such as Figure 1 As shown in the illustration, this application discloses a shoe sole 100, primarily used in athletic shoes for competitions, running, and other similar scenarios. The shoe sole 100 comprises an upper midsole 101, a carbon fiber plate layer 102, and a lower midsole 103, which are stacked and bonded together from top to bottom. By incorporating the carbon fiber plate layer 102, not only is the thickness of the upper midsole 101 increased, improving the cushioning effect, but it also provides better propulsion for the wearer, thereby increasing stride frequency and running speed, thus enhancing the wearer's running performance. Simultaneously, the multiple raised points on the anti-slip bottom layer 104 increase the grip of the shoe sole 100, ensuring stability under various road surface conditions and reducing the risk of foot injury.
[0042] The following will combine Figures 1 to 11 The shoe sole 100 disclosed in the embodiments of this application will be explained and described in detail.
[0043] like Figure 1 As shown, the sole 100 is composed of an upper midsole 101, a carbon fiber plate layer 102, and a lower midsole 103, which are stacked and bonded together in a top-to-bottom order and can be connected and fixed by adhesive. Meanwhile, an anti-slip bottom layer 104 is provided on the side of the lower midsole 103 away from the carbon fiber plate layer 102. The anti-slip bottom layer 104 has multiple raised points to increase grip, thereby increasing the traction of the sole 100, ensuring stability under various road conditions, and reducing the risk of foot injury. Furthermore, the anti-slip bottom layer 104 adopts an integral structure bonded to the lower midsole 103, thereby improving the overall stability and strength of the sole 100. It should be noted that "top to bottom" here refers to the direction of the sole from the foot to the ground.
[0044] like Figure 11 As shown, the carbon fiber plate layer 102 can be formed by sequentially connecting the forefoot section 1021, the midsection section 1022, and the heel section 1023. Among them, as... Figure 5 and Figure 11 As shown, the forefoot segment 1021 is concave towards the lower midsole 103, forming a concave arc shape; the midfoot segment 1022 is convex towards the upper midsole 101, forming a convex arc shape; and the heel segment 1023 is flat, with a fork in the heel segment 1023. The upward convexity of the midfoot segment 1022 provides support for the arch of the foot and enhances the structural strength of the carbon plate layer 102, improving torsional resistance. The forefoot segment 1021, midfoot segment 1022, and heel segment 1023 are respectively concave arc, convex arc, and flat, thus making the carbon plate layer 102 appear approximately "W"-shaped when viewed from the side. The lower surface of the upper midsole 101 is attached to the upper surface of the carbon plate layer 102, which increases the thickness of the upper midsole 101, thereby improving the cushioning effect. At the same time, the upward protrusion of the midfoot section 1022 provides arch support, providing better propulsion for the wearer, thus increasing stride frequency and running speed. Optionally, the carbon plate layer 102 can be made of carbon fiber sheet, and the thickness of the carbon fiber sheet can be 0.8mm to 1.0mm. Preferably, the thickness of the carbon fiber sheet can be 0.9mm, which reduces the weight of the sole while ensuring the strength of the carbon plate layer 102, thereby providing stable propulsion for the wearer.
[0045] To improve the breathability of the sole 100 and further reduce its weight to meet the lightweight requirements of athletic shoes, such as... Figure 3As shown, in some embodiments, multiple ventilation holes 1044 with different diameters can be provided on the anti-slip bottom layer 104, such as 11mm and 5mm, to reduce the weight of the sole 100 and improve its breathability. Optionally, the upper midsole 101 and the lower midsole 103 can be made of TPF (thermoplastic polyester elastomer), which gives the sole 100 better elasticity and softness, improving the comfort of the athletic shoe. Preferably, both the upper midsole 101 and the lower midsole 103 can be made of Nitrogen Pro TPF material, which achieves lightweighting while giving it a high energy return rate. During running, the upper midsole 101 and the lower midsole 103 can quickly absorb the impact force generated when the foot lands and convert it into energy feedback to the feet, providing excellent cushioning and rebound performance and reducing exercise fatigue. It should be noted that Nitrogen Pro is a high-performance foam material.
[0046] In some embodiments, such as Figure 5 As shown, the lower midsole 103 may include a flat segment 1031 and raised segments 1032 located at both ends of the flat segment 1031. The heel segment 1023 of the carbon plate layer 102 may be parallel to the flat segment 1031 of the lower midsole 103 to increase the thickness of the lower midsole 103 and the corresponding heel segment 1023 of the carbon plate layer 102. This allows for adequate heel support when necessary, ensuring the adaptability and flexibility of the athletic shoe. Simultaneously, the front end of the upper midsole 101 may cover the outer front end of the lower midsole 103, thereby ensuring the connection strength between the upper midsole 101 and the lower midsole 103. It should be noted that the front ends of the upper midsole 101 and the lower midsole 103 refer to the toe side of the athletic shoe, i.e., the side facing the wearer's forward direction.
[0047] In some embodiments, such as Figure 3As shown, the raised points may include a first raised point 1041, a second raised point 1042, and a third raised point 1043. The first raised point 1041 may be located at the position of the anti-slip base layer 104 corresponding to the forefoot section 1021; the second raised point 1042 may be located at the position of the anti-slip base layer 104 corresponding to the mid-waist section 1022 and the heel section 1023; and the third raised point 1043 may be located at the position of the anti-slip base layer 104 corresponding to the heel section 1023. The heights of the first raised point 1041, second raised point 1042, and third raised point 1043 decrease sequentially. Optionally, the height of the first raised point 1041 may be 0.25mm to 0.35mm; the height of the second raised point 1042 may be 0.15mm to 0.25mm; and the height of the third raised point 1043 may be 0.10mm to 0.20mm. Preferably, the height of the first protrusion 1041 can be 0.3mm, the height of the second protrusion 1042 can be 0.20mm, and the height of the third protrusion 1043 can be 0.15mm. The higher position of the first protrusion 1041 at the location of the anti-slip bottom layer 104 corresponding to the forefoot section 1021 encourages runners to land on their forefoot first, reducing pressure on the Achilles tendon and decreasing the stretching force on the calf muscles and Achilles tendon at the moment of landing, thus lowering the risk of injury. Simultaneously, forefoot landing allows runners to more easily utilize leg strength for push-off, increasing stride length. Furthermore, the first protrusion 1041 provides better support and elastic feedback for the forefoot, enabling runners to more effectively transfer power to the ground when pushing forward, thereby propelling the body forward and improving running speed and efficiency.
[0048] The sole 100 provided in this application comprises an upper midsole 101, a carbon fiber plate layer 102, and a lower midsole 103, which are stacked and bonded together from top to bottom. The carbon fiber plate layer 102 is composed of a forefoot section 1021, a midfoot section 1022, and a heel section 1023 connected in sequence. The forefoot section 1021 is concave on the side facing the lower midsole 103, while the midfoot section 1022 protrudes on the side facing the upper midsole 101. This not only thickens the upper midsole 101 and improves the cushioning effect but also provides better propulsion for the wearer, thereby increasing stride frequency and running speed. Simultaneously, an anti-slip bottom layer 104 is provided on the side of the lower midsole 103 away from the carbon fiber plate layer 102. The anti-slip bottom layer 104 is bonded to the lower midsole 103 and has multiple raised points, thereby increasing the grip of the sole 100, ensuring stability under various road conditions, and reducing the risk of foot injury.
[0049] The sole 100 provided in this application, by setting a carbon plate layer 102, not only thickens the upper midsole 101 and improves the cushioning effect, but also provides better propulsion for the wearer, thereby achieving the effect of increasing stride frequency and running speed, and improving the wearer's running performance. At the same time, the multiple raised points set on the anti-slip bottom layer 104 can increase the grip of the sole 100, ensure stability under various road conditions, and reduce the risk of foot injury.
[0050] This application also discloses a sports shoe, such as... Figures 5 to 10 As shown, the athletic shoe includes an upper 200 and a sole 100, and the upper 200 and the sole 100 can be connected by adhesive or sewing. The sole 100 is the sole 100 disclosed in the above embodiment; therefore, this athletic shoe possesses all the technical effects of the aforementioned sole 100, which will not be elaborated upon further here.
[0051] In some embodiments, the upper 200 may employ a woven structure formed by an elastic weaving process, and the material of the upper 200 may be a breathable mesh material to ensure the comfort and breathability of the athletic shoe during long-distance running, reducing foot friction and sweat accumulation. The breathable mesh material may be one of polyester fiber, nylon, or spandex.
[0052] It should be noted that athletic shoes can also be equipped with a lightweight locking system in the heel, which can provide adequate support to the heel when necessary, maintaining the adaptability and flexibility of the athletic shoe.
[0053] The terms "first" and "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units may include steps or units not listed, but rather not listed.
[0054] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
