Description

Technical Field

[0001] This application relates to the field of athletic footwear, and more particularly to an athletic footwear with a thermoplastic protective structure. Background Technology

[0002] Specialized sports shoes, such as cycling shoes, roller skates, and ski boots, typically have protective sidewalls on the soles to provide support and protection for the wearer's feet. Existing protective sidewalls are usually molded as a single piece with the sole.

[0003] However, feet of the same size can vary in width and shape, and protective sidewalls can easily cause friction against unsuitable foot shapes, leading to foot injuries. To better fit foot shapes, current practices involve using soft materials for the sidewalls of the upper, but this softness reduces protection, resulting in weaker protective effects.

[0004] Therefore, there is a need for sports shoes that provide good protection while being easy to fit different foot shapes of wearers. Utility Model Content

[0005] In order to provide good protection while being easy to fit different foot shapes of wearers, this application provides a sports shoe with a thermoplastic protective structure.

[0006] The sports shoe with a thermoplastic protective structure provided in this application adopts the following technical solution: A sports shoe with a thermoplastic protective structure includes a sole, an upper, and a thermoplastic structure, wherein the upper is connected to the sole; the thermoplastic structure is connected to the upper and extends circumferentially along the upper, and one side of the thermoplastic structure near the sole is connected to the sole.

[0007] By adopting the above technical solution, after purchasing the shoes, consumers can first put them on, then heat the thermoplastic structure to soften it, and then shape the thermoplastic structure to fit the wearer's foot shape. Furthermore, since the thermoplastic structure hardens again after cooling, it can continue to protect the wearer's feet. Thus, the sports shoes not only have a good protective effect, but also are easy to fit different wearers' foot shapes.

[0008] Optionally, the upper includes an inner lining and an outer layer, with the thermoplastic structure disposed between the inner lining and the outer layer.

[0009] By adopting the above technical solution, the thermoplastic structure is hidden inside the shoe upper, which not only improves the appearance of the sports shoes, but also effectively prevents the thermoplastic structure from being directly worn, thereby extending its service life.

[0010] Optionally, the thermoplastic structure includes a sidewall piece and a heel piece. One end of the sidewall piece is connected to the side of the shoe upper located at the toe, and the other end wraps around the heel of the shoe upper and is connected to the other side of the shoe upper located at the toe. The heel piece is connected to the shoe upper at the heel position, and the width of the heel piece is greater than the width of the sidewall piece.

[0011] By adopting the above technical solutions, the sidewall and heel counters extend circumferentially along the upper to provide comprehensive protection, effectively preventing direct contact between the foot and external objects and enhancing protective performance. The sidewall's design, encircling both sides of the toe, adapts to different foot shapes, reducing the risk of injury due to friction while maintaining good support. The heel counter is wider than the sidewall, providing stronger stability and protection at the heel, further enhancing overall protective performance and meeting the specific protection needs of the feet during exercise.

[0012] Optionally, a groove is provided at the middle position of the side of the heel piece.

[0013] By adopting the above technical solution, the material consumption of the heel piece is reduced on the one hand, and the shaping of the heel piece is also facilitated on the other hand.

[0014] Optionally, the groove is formed on the side of the heel piece near the sole.

[0015] By adopting the above technical solution, a groove is provided on the side of the heel counter near the sole. This design effectively reduces material buildup in this area, thereby improving the fit and making the athletic shoe more suitable for different wearers' foot shapes. Simultaneously, the groove reduces material usage and shoe weight while maintaining protective performance, thus enhancing wearing comfort. The specific location of the groove on the side of the heel counter near the sole reduces the contact area between the heel counter and the sidewall plate, facilitating the shaping of the thermoplastic structure and avoiding friction and discomfort caused by excessive material thickness.

[0016] Optionally, the distance between the heel tab away from the sole and the sole decreases from the middle to both sides.

[0017] By adopting the above technical solution, the width of the heel counter on the side away from the sole decreases from the middle to both sides, so that the heel counter can better fit the wearer's foot shape while ensuring protective performance. This not only improves the comfort of sports shoes, but also effectively reduces friction caused by width mismatch, thereby reducing the risk of foot injury.

[0018] Optionally, the thermoplastic structure has a connecting edge on one side near the sole, the connecting edge extending along the length of the thermoplastic structure, the connecting edge having an angle with the thermoplastic structure, and the connecting edge being used to connect with the sole.

[0019] By adopting the above technical solution and adding a connecting edge, the connection between the thermoplastic structure and the sole is made more stable, reducing the possibility of the thermoplastic structure falling off due to uneven stress during exercise.

[0020] Optionally, the connecting edge has multiple thread holes, which are arranged at intervals along the length of the connecting edge. The thread holes are used for passing through the sewing thread, and the connecting edge is sewn to the sole by the sewing thread.

[0021] By adopting the above technical solution, multiple threading holes are opened on the connecting edge, and the connecting edge is sewn to the sole by passing the sewing thread through the threading holes, making the connection between the thermoplastic structure and the sole more firm and reliable.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating a thermoplastic structure into the upper and extending it circumferentially, this structure can be molded to fit the wearer's foot shape after heating, thereby improving adaptability to different foot shapes. At the same time, as the thermoplastic structure hardens again after cooling, it can also maintain good protective performance. 2. The thermoplastic structure includes sidewall panels and heel panels, forming effective protection in various parts of the shoe and facilitating the cutting of thermoplastic structures; 3. A groove is provided on the side of the heel piece near the sole, which reduces the overlap between the heel piece and the sidewall piece and facilitates the shaping of the thermoplastic structure.

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses an athletic shoe with a thermoplastic protective structure.

[0028] Reference Figure 1 and Figure 2 A sports shoe with a thermoplastic protective structure includes a sole 1, an upper 2, and a thermoplastic structure 3. The upper 2 is connected to the sole 1, and the connection method can be sewing or bonding. The thermoplastic structure 3 is connected to the upper 2 and extends circumferentially along the upper 2. The side of the thermoplastic structure 3 closest to the sole 1 is connected to the sole 1.

[0029] With this design, after purchasing the shoes, consumers can put them on and then heat the thermoplastic structure 3, reshaping it to fit the wearer's foot shape. Alternatively, the thermoplastic structure 3 can be heated first, then the foot can be put into the shoe while the shape of the thermoplastic structure 3 is adjusted and reshaped. This allows the thermoplastic structure 3 to harden and conform to the wearer's foot shape after cooling; and because it hardens again after cooling, it continues to protect the wearer's feet. Therefore, this athletic shoe offers good protection while also easily adapting to different foot shapes.

[0030] In this embodiment, the thermoplastic structure 3 uses a low-temperature hot melt adhesive backrest. The backrest is a key material commonly used in footwear manufacturing, and its function is similar to the "skeleton" of the shoe. The low-temperature hot melt adhesive backrest is a new type of environmentally friendly material, which has the characteristics of having memory flame after shaping, being waterproof and non-deformable, and being able to bond the inner cavity without the need for glue, making it suitable for long-term wear.

[0031] In this embodiment, the heating method for the thermoplastic structure 3 can be as follows: after the wearer puts the shoes on their feet, they put on a waterproof material such as a plastic bag, and then put the shoes into hot water. The thermoplastic structure 3 softens and shrinks under the heat of the hot water. After the thermoplastic structure 3 fits the wearer's foot shape, the shoes can be taken out of the hot water. Alternatively, after putting on the shoes, a hair dryer can be used to heat the thermoplastic structure 3 until it fits the wearer's foot shape.

[0032] A connecting edge 31 is provided on the side of the thermoplastic structure 3 near the sole 1. The connecting edge 31 extends along the length of the thermoplastic structure 3 and forms an angle with the thermoplastic structure 3. The connecting edge 31 is used to connect with the sole 1. Thus, while there is a connection between the upper 2 and the sole 1, the connection between the thermoplastic structure 3 and the sole 1 is also increased, thereby strengthening the connection strength and stability between the upper 2 and the sole 1.

[0033] In this embodiment, the connecting edge 31 is formed by bending the thermoplastic structure 3.

[0034] In this embodiment, the connecting edge 31 is bonded and fixed to the sole 1. In another embodiment, multiple through holes for sewing threads can be pre-drilled on the connecting edge 31, with the multiple through holes arranged at intervals along the length of the connecting edge 31, and the connecting edge 31 is sewn to the sole 1.

[0035] Specifically, in this embodiment, the upper 2 includes an inner lining 21 and an outer layer 22, with the thermoplastic structure 3 disposed between the inner lining 21 and the outer layer 22. This conceals the thermoplastic structure 3 within the upper 2, ensuring the aesthetics of both the upper 2 and the shoe; it also reduces direct wear on the thermoplastic structure 3, extending its service life.

[0036] In this embodiment, the thermoplastic structure 3 includes a sidewall piece 32, a heel piece 33, and a supplementary piece 34. One end of the sidewall piece 32 is connected to one side of the upper 2 located at the toe, and the other end wraps around the heel of the upper 2 and connects to the other side of the upper 2 located at the toe. The heel piece 33 is connected to the upper 2 at the heel position, and the width of the heel piece 33 is greater than the width of the sidewall piece 32. This design divides the thermoplastic structure 3 into the sidewall piece 32 and the heel piece 33. The sidewall piece 32 provides support and protection for the periphery of the upper 2, while the wider heel piece 33 provides effective support and protection at the heel position of the upper 2, thus providing comprehensive protection and ensuring a protective effect.

[0037] The supplementary piece 34 has two pieces, which are respectively connected to the two ends of the sidewall piece 32. The supplementary piece 34 is connected to the side of the sidewall piece 32 away from the sole 1, so that a thermoplastic piece is set at the bending point of the upper 2, and more detailed shaping is performed at this special position to improve the fit and wearing comfort of the shoe.

[0038] Furthermore, a groove 331 is provided in the middle of the side of the heel piece 33, which reduces the material consumption of the heel piece 33, lightens the weight of the sole 1, and improves the wearing comfort of the shoe; on the other hand, it also facilitates the shaping of the heel piece 33.

[0039] In this embodiment, the groove 331 is formed on the side of the heel piece 33 near the sole 1, which reduces the overlap between the heel piece 33 and the sidewall piece 32, making it easier to shape the thermoplastic structure 3.

[0040] In this embodiment, the distance between the heel piece 33 and the sole 1 on the side furthest from the sole 1 decreases from the middle to both sides. This further reduces the material consumption of the thermoplastic structure 3, and also allows the heel piece 33 to better conform to the wearer's foot shape while providing effective protection, facilitating shaping and improving the comfort of the shoe.

[0041] The implementation principle of a sports shoe with a thermoplastic protective structure in this application embodiment is as follows: After the consumer purchases the shoes, the wearer puts the shoes on and then heats the thermoplastic structure 3 until it fits the wearer's foot shape. After the thermoplastic structure 3 cools down, it hardens again and can continue to protect the wearer's feet. Thus, the sports shoe has a good protective effect and is easy to fit different wearers' foot shapes.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
