Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a midsole structure and a shoe incorporating the midsole structure. Background Technology

[0002] The midsole, located between the sole and the upper, plays a crucial role in providing foot support, cushioning, and energy return. Especially in the field of athletic shoes, the choice of materials and structural design of the midsole are of paramount importance to the overall performance of the shoe.

[0003] Traditional athletic shoes typically use a single layer of fabric for the midsole, often needle-punched fabric, which is bonded to the upper using adhesives, stitching, or heat pressing. Because needle-punched fabric has good rigidity and lateral stability, it provides a relatively consistent fit and comfort. However, this midsole structure has limitations. For example, the inherent rigidity of needle-punched fabric can restrict the overall softness of the sole when used with a softer outsole, affecting the wearer's comfort. Furthermore, the prominent and rough horizontal lines on the surface of needle-punched fabric can cause displacement and friction between the insole and midsole during prolonged running, especially when the insole becomes thinner. This can lead to overheating, reducing foot feel and overall comfort. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a shoe midsole structure and a shoe incorporating the midsole structure. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general description, nor is it intended to identify key / important components or describe the scope of protection of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the detailed description that follows.

[0005] The present invention adopts the following technical solution:

[0006] In a first aspect, a shoe midsole structure is provided, comprising: a main shoe piece, a sandwich mesh fabric, and a positioning shoe piece, wherein the main shoe piece has functional compensation inner punches, the sandwich mesh fabric is sewn into the functional compensation inner punches, and the positioning shoe piece is sewn onto the inside of the main shoe piece and covers the sandwich mesh fabric.

[0007] The main shoe piece and the positioning shoe piece are made of needle-punched fabric.

[0008] The thickness of the sandwich mesh is 1.8-2.0 mm.

[0009] The thickness of the main shoe piece and the positioning shoe piece is 1-1.2mm.

[0010] The functional compensation inner punch and the outline shape of the sandwich mesh fabric are consistent with the outline shape of the main shoe piece.

[0011] The sandwich mesh fabric is stitched and spliced ​​onto the main shoe piece along the edge of the functional compensation inner punch, and is connected to the main shoe piece by herringbone stitch, the stitch width of which is 5-6mm.

[0012] The distance between the front edge of the functional compensation inner punch and the left and right side edges of the punch and the front and left and right side edges of the main shoe piece is 18mm, and the distance between the rear edge of the functional compensation inner punch and the rear side edge of the main shoe piece is 50-55mm.

[0013] The positioning shoe piece is connected to the main shoe piece by a chain stitch.

[0014] The distance between the outer front edge and the outer left and right edges of the positioning shoe piece and the outer front edge and the outer left and right edges of the main shoe piece is 9mm, and the distance between the outer rear edge of the positioning shoe piece and the outer rear edge of the main shoe piece is 45-48mm.

[0015] Secondly, a shoe is provided, including the aforementioned midsole structure.

[0016] The beneficial effects of this utility model are:

[0017] 1. This application optimizes and upgrades the midsole structure of the shoe by creating functional compensation internal punches on the main shoe piece and stitching sandwich mesh fabric inside the holes. While maintaining the stability of the midsole structure using the main shoe piece, the overall softness of the midsole is improved by introducing sandwich mesh fabric into the main shoe piece, achieving a good balance between stability and softness.

[0018] 2. By cooperating with the main shoe piece and the positioning shoe piece, after the main shoe piece is fixed to the upper, the positioning shoe piece can be removed to expose the sandwich mesh on the inside of the shoe. This avoids structural deformation that may occur when the upper is connected to the midsole, and has the advantages of being easy to manufacture and process, ensuring a high yield rate.

[0019] 3. This application has holes in the main shoe piece and sandwich mesh fabric is stitched together in the holes. Compared with the existing multi-layer shoe midsole structure, it is thinner, which can not only reduce the overall weight and sole thickness of the shoe, making it lighter, but also makes it particularly suitable for use as the sole structure of sports shoes. Moreover, due to the introduction of sandwich mesh fabric, the shoe midsole structure of this application has better extensibility and breathability, thereby improving wearing comfort.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] like Figure 1-5 As shown, in some illustrative embodiments, a shoe midsole structure is provided, including: a main shoe piece 1, a sandwich mesh fabric 2, and a positioning shoe piece 3.

[0028] The main shoe piece 1 is made of needle-punched fabric, which has high hardness, strength, and abrasion resistance, ensuring the structural stability of the midsole in the front-to-back and left-to-right directions, thus providing consistent fit and tightness. Functional compensation inner perforations 11 are formed on the main shoe piece 1, and sandwich mesh fabric 2 is sewn inside these perforations. During exercise, when the sole of the foot is subjected to pressure, the sandwich mesh fabric 2 provides a certain amount of elasticity to cushion the impact. The sandwich mesh fabric 2 has good breathability, elasticity, and softness. In this application, a sandwich mesh fabric 2 with an elongation of 30%-90% can be selected. Elongation refers to the degree to which a material can stretch under tension. The positioning shoe piece 3 is sewn to the inside of the main shoe piece 1 and covers it with the sandwich mesh fabric 2. During manufacturing, the stitching must be removed before the sole is assembled, and the positioning shoe piece 3 is removed after the shoe is formed. The inside of the main shoe piece 1 refers to the side facing inwards into the shoe.

[0029] The midsole structure of this application comprises a sandwich mesh fabric 2 in the inner region and a main shoe piece 1 in the outer region, which together form the main part of the midsole and are fixed to the upper as an integral structure in subsequent processing. The sandwich mesh fabric 2 in the inner region enhances the breathability, extensibility, and softness of the midsole structure, thereby improving the comfort of the shoe. At the same time, the main shoe piece 1 in the outer region provides good support and anti-deformation ability, ensuring the stability of the structure. Therefore, the midsole structure of this application achieves a good balance between stability and softness, meeting the high performance requirements of sports shoes.

[0030] Furthermore, due to the improved overall elasticity of the midsole structure, the insole and midsole fit more snugly. During long runs, this reduces shifting and friction between the midsole and insole, minimizing overheating and further enhancing comfort. Moreover, compared to existing multi-layered midsole structures, this application is thinner and lighter, making it particularly suitable for use as a sole structure in athletic shoes.

[0031] The introduction of the sandwich mesh fabric 2 may cause structural deformation when the midsole structure is fixed to the upper. Therefore, this application sews a positioning piece 3 to the inside of the main shoe piece 1. The positioning piece 3 is also made of needle-punched fabric, consistent with the main shoe piece 1. The high hardness of the needle-punched fabric helps to improve the overall strength of the midsole. During the process of fixing the midsole structure to the upper, the positioning piece 3 remains on the main shoe piece 1 and covers it with the sandwich mesh fabric 2, providing support for the internal area of ​​the main shoe piece 1, thereby resisting deformation that may occur during processing. This makes the midsole structure of this application more stable and less prone to deformation during processing, thereby improving production efficiency and product quality.

[0032] The positioning shoe piece 3 is connected to the main shoe piece 1 via a chain stitch 13, meaning the positioning shoe piece 3 is fixed to the main shoe piece 1 using a chain stitch method. Chain stitching is an existing sewing technique that uses a series of interlocking loops to form the stitch, including a top thread and a bottom thread. In this application, the top thread is located on the inside of the main shoe piece 1 (the side facing the inside of the shoe), and the bottom thread is located on the outside of the main shoe piece 1 (the side facing the outsole of the shoe). Due to the special structure of the chain stitch, if one end of the stitch is pulled out, the entire stitch will loosen like a chain. Therefore, after the midsole structure of this application is fixed to the upper, the bottom thread is first removed from the outside of the shoe, and then the top thread is removed from the inside of the shoe, allowing the positioning shoe piece 3 to be removed from the main shoe piece 1, exposing the sandwich mesh fabric 2 on the inside of the shoe. Therefore, this application has the advantage of ensuring structural stability during processing while being easy to manufacture.

[0033] The functional compensation inner perforation 11 and the sandwich mesh 2 have the same outline shape as the main shoe piece 1, but are smaller in size. Since the outer outline of the main shoe piece 1 is consistent with the outsole and the bottom of the upper, the shape matching design of the functional compensation inner perforation 11 and the sandwich mesh 2 allows the pedaling pressure to be distributed specifically on the sandwich mesh 2 and the main shoe piece 1. This ensures that the pressure is effectively managed in specific areas of the sole, helps to evenly transfer the pressure to other parts of the shoe, reduces local pressure concentration, and thus improves the wearing experience.

[0034] The sandwich mesh fabric 2 is sewn and stitched onto the main shoe piece 1 along the edge of the functional compensation inner punch 11, and connected to the main shoe piece 1 by herringbone stitch 12. That is, the sandwich mesh fabric 2 is fixed to the main shoe piece 1 by herringbone stitching. Herringbone stitching is an existing sewing technique that can create herringbone stitches to provide a strong connection, effectively resisting stretching and tearing of the stitches during movement. Furthermore, the stitch width of the herringbone stitch 12 is 5-6mm. The relatively wide stitch increases the abrasion resistance of the stitches and the stability of the connection, making the connected part more durable.

[0035] The distance between the front edge of the functional compensation inner punch 11 and the left and right edge of the hole and the front and left and right outer edges of the main shoe piece 1 is 18mm, and the distance between the rear edge of the functional compensation inner punch 11 and the rear outer edge of the main shoe piece 1 is 50-55mm.

[0036] The 18mm design ensures that the sandwich mesh 2 occupies an optimal area, without excessively encroaching on the main shoe piece 1. This allows the midsole structure of this application to simultaneously maintain stability and softness, providing necessary support without compromising the softness and elasticity of the midsole, thus preserving the overall performance of the midsole. The 50-55mm design provides sufficient support area for the main shoe piece 1 at the heel, helping to maintain the overall shape of the shoe. Furthermore, by retaining more support and cushioning at the heel, comfort during extended wear can be significantly improved.

[0037] The distance between the front outer edge and the left and right outer edges of the positioning shoe piece 3 and the front outer edge and the left and right outer edges of the main shoe piece 1 is 9mm. The distance between the rear outer edge of the positioning shoe piece 3 and the rear outer edge of the main shoe piece 1 is 45-48mm. The 9mm and 45-48mm dimensions ensure that the positioning shoe piece 3 completely covers the sandwich mesh fabric 2, ensuring that the structure does not undergo significant deformation when the midsole structure is fixed to the upper. Moreover, this size design will not affect the fixation between the midsole and the upper, nor will it affect subsequent stitching removal.

[0038] The thickness of the sandwich mesh fabric 2 is 1.8-2.0 mm; the thickness of the main shoe piece 1 and the positioning shoe piece 3 is 1-1.2 mm. Because the sandwich mesh fabric 2 has better elasticity and a greater degree of deformation, this application designs the thickness of the sandwich mesh fabric 2 to be slightly thicker than the thickness of the main shoe piece 1 and the positioning shoe piece 3 to ensure wearing comfort. Furthermore, the appropriate thickness of the sandwich mesh fabric 2, the main shoe piece 1, and the positioning shoe piece 3 can provide better comfort and support, better distribute pressure points on the foot, and reduce fatigue after prolonged wear.

[0039] In some illustrative embodiments, a shoe is provided, including as follows: Figure 1-5 The shoe midsole structure shown includes: a main shoe piece 1, a sandwich mesh fabric 2, and a positioning shoe piece 3.

[0040] After the midsole structure is connected to the upper using processes such as gluing, sewing, or hot pressing, remove the bottom thread of the chain stitch 13, then connect the outsole, then tear off the top thread on the inside of the shoe, remove the positioning shoe piece 3, expose the sandwich mesh fabric 2 on the inside of the shoe, and then insert the insole.

[0041] This application optimizes and upgrades the midsole structure of the shoe by creating functional compensation inner punch holes 11 on the main shoe piece 1 and stitching sandwich mesh fabric 2 inside these holes. While maintaining the stability of the midsole structure using the main shoe piece 1, the overall softness of the midsole is improved by introducing sandwich mesh fabric 2 onto the main shoe piece 1, achieving a good balance between stability and softness.

[0042] By cooperating with the main shoe piece 1 and the positioning shoe piece 3, once the main shoe piece 1 is fixed to the upper, the positioning shoe piece 3 can be removed, exposing the sandwich mesh fabric 2 on the inside of the shoe. This avoids structural deformation that may occur when the upper is connected to the midsole, and has the advantages of being easy to manufacture and process, ensuring a high yield rate.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
