[0030] like Figure 1-5 The image shown is an embodiment provided by this utility model.

[0031] This utility model embodiment provides an adjustable heel counter for cycling shoes, including: a sole 10, an upper 20, and a heel counter 30. The upper 20 and the heel counter 30 are respectively connected to the sole 10. The connection method and overall shape of the upper 20, the heel counter 30, and the sole 10 are similar to those of conventional cycling shoes, and existing cycling shoes can be used as a reference. Specifically, the heel counter 30 has an installation opening 31, which is located in the middle or on both sides of the heel counter 30. It is usually set at a position directly corresponding to the heel or on both sides of the heel when the person is wearing the cycling shoe. An adjustment plate 32 is detachably installed inside the installation opening 31. The position of the adjustment plate 32 corresponds exactly to the back or sides of the person's heel, which can better wrap the heel. In addition, the installation opening 31... The size of 1 can also be set to be equivalent to the entire heel counter 30, meaning the entire heel counter 30 is left empty to install the adjustment plate 32, essentially replacing the entire heel counter 30. The adjustment plate 32 is made of thermoplastic material and has an outwardly convex curved surface. The shape of the adjustment plate 32 roughly fits the heel, and the curvature of the adjustment plate 32 can be reshaped and adjusted by heating. Users can remove the adjustment plate 32 themselves after purchase and reshape and adjust its curvature according to their own wearing conditions to make it fit their heel better, thereby improving the fit between the shoe and the foot, and thus improving the foot's power generation efficiency and pedaling efficiency when wearing the shoe.

[0032] Specifically, the adjustment plate 32 is a low-temperature thermoplastic carbon fiber plate. Low-temperature thermoplastic carbon fiber plates are generally made of low-temperature thermoplastic resins (such as certain modified PP or PE) as the matrix. They can be repeatedly softened and reshaped by heating. The thickness of the adjustment plate 32 is 1.5-3mm, and the heat distortion temperature is 80-100℃. Users can use heating tools such as electric ovens and hot air guns to heat and shape the adjustment plate 32. In practical applications, in order to facilitate consumers, the sellers of cycling shoes can equip the sales points with heating tools to provide heating and shaping services for the adjustment plate 32 to the buyers.

[0033] Specifically, the mounting opening 31 is elliptical or oblong, and its major axis is aligned with the width direction of the heel counter 30.

Figure 2-3 As shown, the inner edge of the mounting port 31 is provided with a hook and loop fastener 311, and the outer edge of the adjustment plate 32 is provided with a hook and loop hook fastener 321. The hook and loop hook fastener 321 is connected to the hook and loop fastener 311. Of course, it is also possible to interchange the positions of the hook and loop fastener 311 and the hook and loop hook fastener 321.

[0035] Furthermore, the hook and loop fastener 321 and / or the loop and loop fleece 311 are arranged in a ring or in a multi-point wrap-around manner. For example, both the hook and loop fastener 321 and the loop and loop fleece 311 are ring-shaped, both the hook and loop fastener 321 and the loop and loop fleece 311 are multi-point wrap-around, the hook and loop fastener 321 is ring-shaped and the loop and loop fleece 311 is multi-point wrap-around, and so on.

[0036] In one embodiment, please refer to the appendix. Figure 4 As shown, the inner side of the adjustment plate 32 is provided with anti-slip texture 322. The anti-slip texture 322 is distributed in a wave shape or dot matrix pattern, which can make the contact between the heel and the adjustment plate 32 more stable and less prone to slipping.

[0037] In another embodiment, please refer to the appendix. Figure 5 As shown, the inner side of the adjustment plate 32 is detachably provided with a soft pad 323. The soft pad 323 is 2-5mm thick and has a breathable hole structure, which can improve the comfort when wearing it and improve the wrapping of the heel, making it less likely to slip.

[0038] Furthermore, a cushioning layer (not shown in the attached diagram) is provided on the inner side of the heel counter 30. The cushioning layer is fitted to the heel counter 30 and is made of silicone or memory foam material, which can improve wearing comfort.

[0039] Furthermore, a miniature heating element 33 and a temperature sensor 34 are provided on the outer side of the heel counter 30. The heating element 33 and the temperature sensor 34 are thermally connected to the adjustment plate 32. The heating element 33 can be powered by an external power source, and the temperature sensor 34 can use a built-in rechargeable battery for long-term use. The heating element 33 can heat the adjustment plate 32, and the temperature sensor 34 can measure the temperature of the adjustment plate 32 in real time. When the heating element 33 heats the adjustment plate 32 to a temperature range suitable for molding, the adjustment plate 32 can be removed for molding or directly molded without disassembly.
