[0023] like Figures 1 to 5 As shown, this application embodiment provides a men's shoe with a full leather upper 11 and a full leather midsole stitched together 360 degrees with a dual-density shock-absorbing sole, comprising: The full leather upper 11, full leather midsole 12 and dual-density sole are connected sequentially from top to bottom. The full leather upper 11 and full leather midsole 12 are formed into an integrated structure by continuous 360° stitching around the perimeter. The dual-density sole comprises an bonded upper shock-absorbing layer 131 and a lower abrasion-resistant layer 132.

[0024] "Full leather upper" refers to the fact that the outer covering material of the shoe is made entirely of top-grain cowhide. This material not only has excellent breathability and comfort, but also provides good abrasion resistance.

[0025] The full-leather midsole 12 is located inside the upper and above the sole, and is also made of top-grain cowhide. It is designed to enhance the overall strength and support of the shoe, and improve the wearer's comfort through breathable design.

[0026] The full-grain cowhide upper 11 and the full-grain cowhide insole 12 are 1.3mm-1.5mm thick and are chrome-tanned.

[0027] Continuous 360° four-sided stitching refers to using high-strength polyester thread to sew the upper and midsole together along the edges, forming a seamless and sturdy overall structure. This process effectively avoids the problem of easy separation caused by traditional adhesive bonding, while improving the durability and structural stability of the shoe. The stitching thread is made of 0.6mm diameter polyester thread with a tensile strength ≥50kgf.

[0028] The men's shoe, featuring a full leather upper 11 and a full leather midsole with a 360° stitched dual-density shock-absorbing sole according to the embodiments of this application, adopts an integrated structure formed by continuous 360° stitching of the full leather upper 11 and full leather midsole 12. This seamless combination not only greatly enhances the overall strength and durability of the shoe but also effectively avoids the problem of easy separation caused by traditional adhesive processes, while improving the breathability and wearing comfort of the shoe. Furthermore, the men's shoe is equipped with a dual-density sole, including an upper shock-absorbing layer 131 and a lower abrasion-resistant layer 132. The upper layer provides soft cushioning, effectively absorbing the impact force generated during walking, while the lower layer increases the abrasion resistance and stability of the shoe. The two layers are combined through a special adhesive process, and the junction is designed with a wave shape to disperse stress, ensuring stability and durability over long-term use.

[0029] In addition, the forefoot area of ​​the sole features flex grooves to enhance flexibility, and the built-in ventilation holes in the midsole, together with the breathable mesh fabric in the upper lining, form an air circulation channel, further enhancing the ventilation effect inside the shoe and making it more comfortable to wear.

[0030] In some embodiments of this application, the stitching connecting the full-leather upper 11 and the full-leather midsole 12 is made of polyester thread, with a stitch length of 2.5 mm / stitch to 3 mm / stitch. High-strength polyester thread is used for stitching, as this material has excellent tensile strength and durability, ensuring that the shoes are less prone to unraveling or damage during long-term use. Specifically, the stitch length is set to 2.5 mm to 3 mm / stitch. This fine stitch length design ensures both strong stitching and aesthetics, while also allowing for the natural elasticity of the material. A smaller stitch length provides higher stitch density, enhancing structural stability; while a moderate stitch length avoids excessive wear or loss of elasticity due to overly dense stitching, further improving the overall durability and wearing comfort of the shoe. Furthermore, a reasonable stitch length effectively distributes stress generated during walking, extending the shoe's lifespan and maintaining its good appearance.

[0031] In some embodiments of this application, the upper damping layer 131 comprises a polyurethane layer with a Shore hardness of 30 to 50. The lower wear-resistant layer 132 includes a rubber layer with a Shore hardness of 50 to 55.

[0032] The upper shock-absorbing layer 131 is made of polyurethane material with a Shore hardness of 30 to 50. Polyurethane within this hardness range provides excellent softness and cushioning, effectively absorbing the impact of walking, reducing pressure on the foot joints, and providing a comfortable walking experience for the wearer. Choosing this hardness range also ensures sufficient support while providing adequate elasticity to adapt to different gaits and ground conditions.

[0033] The lower abrasion layer 132 uses a rubber material with a Shore hardness of 50 to 55. Rubber in this hardness range not only possesses excellent abrasion resistance, maintaining a long service life under various surface conditions, but also provides the necessary rigidity and stability to ensure a stable landing with every step, increasing the shoe's safety and durability. Furthermore, the appropriate rubber hardness effectively improves the shoe's grip, especially on wet and slippery surfaces, further enhancing its anti-slip performance.

[0034] By precisely selecting and matching materials with different hardness ranges to form the upper shock-absorbing layer 131 and the lower abrasion-resistant layer 132, a perfect combination of shock absorption and abrasion resistance is achieved, which not only meets the user's needs for comfort, but also ensures the reliability and safety of the shoes in long-term use.

[0035] In some embodiments of this application, a spherical massage body 14 is provided on the upper shock-absorbing layer 131, and an exhaust hole 15 is formed on the surface of the upper shock-absorbing layer 131.

[0036] The spherical massage elements 14, located on the surface of the upper shock-absorbing layer 131, provide a gentle massage to the soles of the feet during walking, promoting blood circulation and reducing fatigue. This design is particularly suitable for people who need to stand or walk for long periods of time, helping to relieve foot pressure and discomfort through continuous micro-stimulation and improving overall wearing comfort.

[0037] The ventilation holes 15 distributed on the upper shock-absorbing layer 131 enhance air circulation, helping to expel accumulated moisture and heat from inside the shoe and maintain a dry environment. This feature is crucial for maintaining foot health, especially in hot or humid environments, effectively reducing discomfort caused by sweating and the possibility of bacterial growth, providing wearers with a fresher and more comfortable wearing experience.

[0038] In some embodiments of this application, a shock-absorbing chamber 16 suitable for installing an upper shock-absorbing layer 131 is formed on the lower wear-resistant layer 132, and the shock-absorbing chamber 16 is distributed in the foot-stepping area of ​​the forefoot of the lower wear-resistant layer 132.

[0039] The shock-absorbing chamber 16, located on the lower abrasion-resistant layer 132, is a special structure designed specifically for embedding into the upper shock-absorbing layer 131. By precisely matching the shape and size of the upper shock-absorbing layer 131, it ensures that the two can be tightly integrated to form a unified structure. This design not only enhances the stability of the shoe but also makes the shock absorption effect more significant, especially in the forefoot area, which bears a large impact.

[0040] The shock absorber 16 is concentrated in the forefoot's foot contact area because the forefoot is the first part to contact the ground and bear the impact when walking or running. Placing the shock absorber 16 here can effectively absorb and disperse the impact force from the ground, reduce the pressure on joints such as the knees and ankles, and provide better protection and support.

[0041] In some embodiments of this application, the dual-density sole further includes a steel paper support layer; The steel-paper support layer is located in the foot tread area of ​​the lower wear-resistant layer 132.

[0042] The steel-paper support layer is a special support layer located in the heel area of ​​the lower abrasion layer (132). Steel-paper is a high-strength and lightweight material with excellent resistance to compression and deformation. Using it as a support layer can effectively enhance the rigidity of the shoe in the heel area, providing a more stable support effect, helping to maintain the natural posture of the foot, and reducing fatigue caused by prolonged walking or standing.

[0043] The steel-flecked support layer is positioned in the heel counter area because the heel bears the majority of the body weight during walking or running and requires sufficient support to maintain gait stability. Adding a support layer to this crucial area not only enhances the shoe's overall support but also helps distribute pressure, reduce impact on the heel, and protect the user's joint health.

[0044] In some embodiments of this application, anti-slip studs 18 are provided on the ground-contact side of the lower wear-resistant layer 132. The anti-slip studs 18 are distributed on the ground-contact side of the lower wear-resistant layer 132, i.e., the part that directly contacts the ground. They are typically made of high-hardness, wear-resistant materials, such as rubber or special synthetic materials, ensuring excellent grip under various ground conditions. This design is particularly suitable for walking on wet, uneven, or complex terrain, effectively preventing the risk of slipping due to insufficient ground friction.

[0045] In some embodiments of this application, shock-absorbing balls 19 are provided on the ground-contact side of the lower wear-resistant layer 132. The shock-absorbing balls 19 are located on the ground-contact side of the lower wear-resistant layer 132. They are typically made of materials with high elasticity and good cushioning properties, such as specially formulated rubber or polyurethane. The shock-absorbing balls 19 are designed to absorb and disperse the impact force from the ground during walking or running, thereby reducing the impact on the feet and joints.

[0046] In some embodiments of this application, checkerboard grooves 20 are also formed on the ground contact side of the lower wear-resistant layer 132; The depth of the checkerboard grooves 20 is 1.5 mm to 2.5 mm, and the grid length is 20 mm to 25 mm.

[0047] The checkerboard grooves 20 are distributed in a checkerboard pattern on the ground contact side of the underlying abrasion layer 132. The checkerboard design is not only aesthetically pleasing but, more importantly, practical. The groove layout effectively increases the friction area between the sole and the ground, thereby improving the shoe's grip and stability under various surface conditions.

[0048] The depth of the checkerboard grooves 20 is 1.5 mm to 2.5 mm. This depth ensures sufficient friction without compromising the overall durability of the shoe or adding unnecessary weight due to excessive depth.

[0049] Each checkerboard square is 20 to 25 millimeters long. Grooves within this size range maximize flexibility and adaptability without compromising the shoe's structural strength, allowing the shoe to better fit different terrain variations.

[0050] In some embodiments of this application, a groove-shaped stitching groove 21 is provided at the junction of the full leather midsole 12 and the dual-density sole; The groove width of the groove 21 is 0.5 mm to 1.0 mm, and the depth is 1.0 mm to 1.5 mm.

[0051] The grooved stitching channel 21 is a special recessed design located at the junction of the full-leather midsole 12 and the dual-density outsole. By setting the grooved stitching channel 21 at these locations, a more stable embedding position can be provided for the stitching, thereby enhancing the strength of the connection. In addition, this design also helps to distribute stress and prevent cracking or separation due to long-term use.

[0052] The width of the groove 21 is set to be between 0.5 mm and 1.0 mm. This range of groove width ensures that the suture has enough space to be firmly fixed, without affecting the stability of the overall structure due to excessive width.

[0053] The depth of the grooved stitching 21 is 1.0 mm to 1.5 mm. This appropriate depth not only protects the stitching from external abrasion but also further enhances the tensile strength of the joint, extending the lifespan of the shoe.

[0055] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
