Description

Technical Field

[0001] The utility model relates to a composite sole for spiked shoes. Background Art

[0002] At present, spiked shoes are widely used in many fields, especially in sports competitions and outdoor activities. Traditional spiked shoe soles are mostly made of a single material, such as rubber or PU materials, but these materials have certain limitations in terms of wear resistance, cushioning and grip. For example, although the rubber sole has good wear resistance, its cushioning performance is relatively poor; while the PU material has good cushioning performance, but insufficient wear resistance. In addition, the soles of a single material are also difficult to meet the needs of different sports venues in terms of grip. Utility Model Content

[0003] Therefore, in view of the above-mentioned problems, the present invention proposes a composite sole for spiked shoes, which optimizes the combination of properties of different materials so that the spiked shoes have better stability and cushioning performance during use.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a composite sole for spiked shoes, comprising a sole body, wherein the sole body comprises a PU upper layer, a rubber middle layer and a felt bottom layer bonded in sequence, a side surface of the rubber middle layer bonded to the felt bottom layer is provided with a plurality of spike mounting seats integrally formed therewith, and the felt bottom layer is provided with clearance holes for the spike mounting seats to pass through.

[0005] As a further improvement, a side surface of the rubber middle layer bonded to the PU upper layer is provided with a plurality of protrusions integrally formed therewith, and the protrusions are embedded in the PU upper layer.

[0006] Further improved, in the PU upper layer, the thickness of the heel area is 12-18 mm, and the thickness of the forefoot area is 6-10 mm.

[0007] According to a further improvement, the thickness of the rubber middle layer is 1-3 mm.

[0008] As a further improvement, the thickness of the felt bottom layer is 6-12 mm, and the height of the spike mounting seat is consistent with the thickness of the felt bottom layer.

[0009] As a further improvement, the shoe spike mounting seat is cylindrical, and its diameter is 12-20 mm.

[0010] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows: Through the composite structure provided in the sole of the present utility model, the studded shoes have better stability and cushioning performance during use. Among them, the PU upper layer provides a soft and comfortable wearing experience, the rubber middle layer provides a firm support for the installation of the studs, ensuring the stability and durability of the studded shoes, and the felt bottom layer can improve the anti-slip performance of the sole, providing good stability for the user when walking on smooth rocks, and at the same time further enhancing the cushioning performance of the sole, reducing the fatigue feeling of the wearer during long-term use; further, by providing protrusions in the rubber middle layer, the connection strength between it and the PU upper layer is strengthened; further, by optimizing the thickness ratio of each layer, the sole has better support and comfort in different regions. The thicker PU upper layer in the heel area can absorb more impact force and reduce the impact on the heel, while the thinner design in the forefoot area ensures flexibility and lightness, making the wearer more agile during exercise.

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Refer to Figures 1-3, this embodiment provides a composite sole for a spiked shoe, including a sole body. The sole body includes a PU upper layer 1, a rubber middle layer 2, and a felt bottom layer 3 that are adhesively bonded in sequence. On one side of the rubber middle layer 2 that is adhesively bonded to the felt bottom layer 3, there are a plurality of stud mounting seats 22 integrally formed therewith. The stud mounting seats 22 are cylindrical. The felt bottom layer 3 is provided with a clearance hole 31 for the stud mounting seats 22 to pass through. The clearance hole 31 is in interference fit with the stud mounting seats 22. The felt bottom layer 3 is made of fibers and has good friction, which can improve the anti-slip performance of the sole and provide good stability for the user when walking on a smooth rock. On one side of the rubber middle layer 2 that is adhesively bonded to the PU upper layer 1, there are a plurality of protrusions 21 integrally formed therewith. The protrusions 21 are embedded in the PU upper layer 1. The outer surface of the PU upper layer 1 is a matte surface. Among them, the setting positions of the protrusions 21 correspond one-to-one with the positions of the stud mounting seats 22, so that while strengthening the connection strength with the PU upper layer 1, it also provides more thickness support for the installation of the studs.

[0018] The sole of the present utility model has better stability and buffering performance during the use of the spiked shoe through the provided composite structure. Among them, the PU upper layer 1 provides a soft and comfortable wearing experience. The rubber middle layer 2 provides a firm support for the installation of the studs, ensuring the stability and durability of the spiked shoe. The felt bottom layer 3 can improve the anti-slip performance of the sole and also provide good stability for the user when walking on a smooth rock. At the same time, it further enhances the buffering performance of the sole, reducing the fatigue feeling of the wearer during long-term use.

[0019] In this embodiment, in the PU upper layer 1, the thickness of its heel area is 12 - 18 mm, the thickness of its forefoot area is 6 - 10 mm, the thickness of the rubber middle layer 2 is 1 - 3 mm, the thickness of the felt bottom layer 3 is 6 - 12 mm, the height of the stud mounting seats 22 is the same as the thickness of the felt bottom layer 3, and the diameter is 12 - 20 mm.

[0020] Although the present utility model is specifically shown and described in combination with the preferred implementation embodiments, those skilled in the art should understand that various changes can be made to the present utility model in terms of form and details without departing from the spirit and scope of the present utility model defined by the appended claims, and all of them fall within the protection scope of the present utility model.
