[0020] Example
[0021] Please see Figures 1-3This utility model provides a three-layer shock-absorbing and breathable sole suitable for casual shoes. Its structure includes an inner sole 2 and an insole 3. The insole 3 is installed on the upper end of the inner sole 2, and an outer sole 1 is provided on the bottom of the inner sole 2. An installation groove 21 is provided on the front end of the top of the inner sole 2, and a heel shock-absorbing module 22 is provided on the rear end of the top of the inner sole 2. An arch support plate 23 is provided on the top of the heel shock-absorbing module 22, and the front end of the arch support plate 23 is installed in the installation groove 21. A full-length cushioning plate 24 is provided on the bottom of the inner sole 2, and the full-length cushioning plate 24 covers the entire inner sole 2.
[0022] The insole 3 is made of EVA material, a lightweight, soft, and elastic polymer material. The insole 3 has a honeycomb-shaped perforation with a pore diameter of 3-5mm and a pore spacing of 8-10mm. The perforated structure forms an air convection channel to accelerate the expulsion of heat and moisture from inside the shoe. The top surface of the insole 3 is covered with a breathable mesh fabric 4. The breathable mesh fabric 4 has a fiber spacing of 0.2-0.3mm. The surface of the mesh fabric absorbs sweat from the feet, and together with the drainage channel at the bottom of the insole, it guides the moisture to diffuse towards the edge of the sole.
[0023] The arch support plate 23 is made of glass fiber reinforced plastic and covers the arch area in an Ω shape. It has a thickness of 1.5-2.0mm. The arch support plate maintains the natural curvature of the arch and reduces excessive deformation of the arch during walking.
[0024] The full-length cushioning plate 24 is made of plastic polyurethane with a thickness of 1.0-1.2mm. The full-length cushioning plate 24 evenly distributes the pressure on the sole of the foot, reducing local pressure on the forefoot and heel.
[0025] The heel shock absorption module 22 is made of silicone, and the end face of the heel shock absorption module 22 has a hemispherical protrusion 221 with a diameter of 15-20mm and a thickness of 3-5mm. The heel shock absorption module 22 absorbs the impact of the heel hitting the ground and reduces the transmission of vibration to the leg.
[0026] The bottom end face of the outer sole 1 is provided with a wave pattern 11 with a depth of 2.5-3.0mm and a spacing of 5-8mm. The outer sole 1 is also provided with a sole anti-slip layer 12. The sole anti-slip layer 12 is provided with a cushioning block 13 at the heel. The end face of the cushioning block 13 is arc-shaped. The wave pattern enhances the friction between the sole and the ground and improves the grip when walking and pushing off the ground.
[0027] Working principle: The honeycomb perforation in the upper insole 3 is combined with the breathable mesh fabric 4 to form a three-dimensional breathable system that absorbs air from the top, guides it in the middle, and drains it from the bottom. When walking, the movement of the foot drives the airflow, realizing air circulation inside the shoe. The heel shock absorption module 22 absorbs impact energy through elastic deformation, and the mid-layer full-length cushioning plate 24 evenly distributes the impact force to the entire foot, reducing local pressure peaks and playing a shock absorption role. The arch support plate 23 restricts excessive arch collapse through a rigid structure, and works with the full-length cushioning plate 24 to maintain the balance of force on the sole of the foot and reduce walking fatigue.
