Description

Technical Field

[0001] This utility model relates to the field of midsole technology, and in particular to an embedded, flex-resistant midsole. Background Technology

[0002] The midsole is a key component in the shoe structure located between the upper and the outsole. It mainly plays a role in support, cushioning, and shock absorption, directly affecting the comfort and stability of wearing the shoe.

[0003] In existing technologies, shoe midsoles often bend and deform during processing due to unreasonable structural design, resulting in insufficient product dimensional accuracy and affecting subsequent assembly. Simultaneously, the shape of traditional midsoles does not conform well to the physiological curves of the human foot, leading to insufficient comfort and fatigue during wear. Furthermore, it is difficult to balance support and softness in the midsole; some midsoles are too supportive, resulting in insufficient softness, while others are too soft and lack support. Additionally, there are shortcomings in the midsole's moisture resistance, the accuracy of component assembly and positioning, compatibility with the entire shoe, anti-slip effect, and the ease of quality inspection of internal components. Furthermore, improper selection of materials between different layers can easily lead to delamination and edge lifting, affecting the lifespan and performance of the midsole. Therefore, there is an urgent need for an embedded, bend-resistant midsole that can solve the above problems. Utility Model Content

[0026] like Figures 1 to 3 As shown, this is an embodiment of the present invention, which relates to an embedded flexural midsole, including a midsole body 10 that is adapted to the shape of a shoe sole. The midsole body 10 includes an upper midsole 20 and a lower midsole 30 stacked sequentially. A flexural reinforcement layer 40 is embedded between the upper midsole 20 and the lower midsole 30. The flexural reinforcement layer 40 is used to prevent the midsole body 10 from bending during the processing.

[0027] Specifically, by setting up an upper midsole 20, a lower midsole 30, and a flexural reinforcement layer 40 embedded between them, the main body of the midsole 10 is shaped to fit the sole. The flexural reinforcement layer 40 can effectively prevent the main body of the midsole 10 from bending during processing, ensuring the stability of the midsole structure during processing, avoiding difficulties in subsequent assembly or insufficient product dimensional accuracy due to processing deformation. At the same time, the layered structure provides basic structural strength for the midsole, meeting the basic support requirements of footwear products for the midsole.

[0028] like Figure 2 As shown, the midsole body 10 has a bent shape structure adapted to the physiological curve of the foot. This bent shape structure is used to improve the fit and comfort when wearing the shoe. Specifically, the midsole body 10 adopts a bent shape adapted to the physiological curve of the foot and conforms to the natural curvature of the human foot. This allows the midsole to better fit the foot when worn, distribute foot pressure, reduce discomfort during walking or exercise, significantly improve the fit and comfort when wearing the shoe, and reduce fatigue after prolonged wear.

[0029] like Figure 1 As shown, the upper part 20 of the midsole is a rigid support plate, and the front end of the upper part 20 of the midsole is provided with a soft area 21, which is used to enhance the soft touch during use. Specifically, the upper part 20 of the midsole is set as a rigid support plate, which can provide reliable support for the foot and prevent excessive deformation of the foot, while the soft area 21 at the front end can enhance the soft touch during use, achieving a balance between support and softness, which not only ensures the support and protection of the foot by the midsole, but also improves the comfort experience of the toes.

[0030] like Figure 1 As shown, the surface of the soft area 21 is provided with an elastic cotton layer 22. Specifically, the elastic cotton layer 22 further enhances the softness and elasticity of the soft area 21, making the touch of the toe contact area more comfortable. At the same time, the elastic cotton layer 22 has a certain cushioning effect, which can absorb the impact force during walking and reduce the vibration of the toes.

[0031] like Figure 1 As shown, the rear surface of the upper part 20 of the midsole is provided with a moisture-proof paper layer 23, and the two ends of the moisture-proof paper layer 23 are respectively provided with elongated slotted through holes 24. Specifically, the moisture-proof paper layer 23 can effectively prevent external moisture from penetrating into the interior of the midsole, protect the various components of the midsole from moisture, and extend the service life of the midsole. The elongated slotted through holes 24 at both ends of the moisture-proof paper layer 23 facilitates the connection and assembly of the midsole with footwear components such as the sole and upper, improving assembly efficiency.

[0032] like Figure 1As shown, the surface of the moisture-proof paper layer 23 is provided with a plurality of positioning slots 25 for positioning and fitting. Specifically, the positioning slots 25 can provide precise positioning for the assembly of various components of the midsole, ensuring that components such as the upper part of the midsole 20, the bending reinforcement layer 40, and the lower part of the midsole 30 are in the correct position during assembly, avoiding structural instability or functional failure caused by misalignment during assembly, and improving product consistency and pass rate.

[0033] like Figure 3 As shown, the surface of the lower part of the midsole 30 is provided with a lower fabric 31, and the rear ends of the lower fabric 31 are respectively provided with slots 32, which are irregularly shaped. Specifically, the lower part of the midsole 30 is provided with a lower fabric 31, the material of which has a certain degree of flexibility and adaptability. The irregular slots 32 on both rear ends are also connected to the elongated through holes 24, which can be adapted to the structure of other shoe components, facilitate the flexible connection between the midsole and surrounding components, improve the compatibility of the midsole and the overall shoe structure, and at the same time, the irregular shape design can meet specific assembly space requirements.

[0034] like Figure 3 As shown, the front end of the lower part of the midsole 30 is provided with an anti-slip area 33, and the anti-slip area 33 is provided with a plurality of anti-slip holes 34. Specifically, the anti-slip area 33 and the distributed anti-slip holes 34 at the front end of the lower part of the midsole 30 can increase the friction between the midsole and the outsole. By increasing the friction, a stable connection between the midsole and the outsole is achieved, preventing relative sliding between the two during use, ensuring the stability of the overall structure of the footwear, and ensuring the coordinated action of the midsole and the outsole during walking or exercise.

[0035] like Figure 3 As shown, the anti-slip zone 33 has several open holes 35, which are used to observe whether there are defects in the bending reinforcement layer 40. Specifically, the open holes 35 of the anti-slip zone 33 allow for direct observation of whether there are defects such as damage, wrinkles, or misalignment in the bending reinforcement layer 40, facilitating quality inspection during the production process and quality verification before leaving the factory, timely removal of unqualified products, ensuring product quality stability, and reducing after-sales problems.

[0036] like Figure 3 As shown, the surface of the bending reinforcement layer 40 is provided with a middle fabric 41. Both the middle fabric 41 and the lower fabric 31 are made of nylon, polyester, glass fiber composite, or carbon fiber composite fabric. Specifically, the middle fabric 41 and the lower fabric 31 of the bending reinforcement layer 40 are made of materials such as nylon, polyester, glass fiber composite, or carbon fiber composite fabric. These materials have good bending resistance, strength, and durability, which can meet the bending requirements of the midsole. At the same time, the selection of the same or similar materials improves the compatibility and bonding strength between the layers, reduces problems such as delamination and edge lifting caused by material differences, and extends the service life of the midsole.

[0037] The working principle of this utility model is as follows:

[0038] The embedded flex-resistant midsole consists of a layered upper midsole 20, a lower midsole 30, and a flex-resistant reinforcement layer 40, forming the main body 10 of the midsole. The flex-resistant reinforcement layer 40 provides support during processing, preventing the main body 10 from bending and deforming, and ensuring processing accuracy. The main body 10 adopts a flexed shape adapted to the physiological curve of the foot, conforming to the natural bending state of the foot during wear and distributing pressure by fitting the foot snugly. The rigid support plate of the upper midsole 20 provides support, while the soft front area 21 and elastic cotton layer 22 enhance the soft touch and cushioning effect of the toe area through material properties. The moisture-proof paper layer 23 at the rear of the upper midsole 20 blocks moisture, and its elongated through-hole 24 and positioning groove... Holes 25 assist in connecting with other components and positioning each layer during assembly; the lower fabric 31 of the lower part of the midsole 30 is flexible, and the irregular groove 32 at the rear end adapts to other components of the shoe to achieve flexible connection; the anti-slip holes 34 in the front anti-slip zone 33 increase the friction with the sole to achieve a stable connection between the two, ensuring a solid connection; the open holes 35 provide a channel for observing whether there are defects in the bending reinforcement layer 40, which is convenient for quality inspection; the middle fabric 41 and the lower fabric 31 are made of bending-resistant and high-strength materials to ensure the overall bending resistance of the midsole and the firmness of the interlayer bonding. All components work together to achieve the functions of structural stability, comfortable fit, convenient assembly, solid connection, safety and durability of the midsole.

[0039] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
