[0029] Reference Figs. 1-3 The utility model discloses an area shoe -pad, including shoe -pad body 1, the shoe -pad body 1 bottom is provided with toe layer 11, forefoot layer 12 and heel layer 13. The density of toe layer 11 is less than the density of forefoot layer 12, and the density of forefoot layer 12 is less than the density of heel layer 13. The shoe -pad uses different density materials according to different areas (such as arch, forefoot, heel) of foot to provide targeted support and buffer, and the overall comfort is higher.
[0030] Further, the toe layer 11 is made of PU material with a density of 80-150 kg / m3. The forefoot layer 12 is made of PU material with a density of 150-190 kg / m3. The heel layer 13 is made of PU material with a density of 200-300 kg / m3 or Poron material. The insole body 1 is made of PU foam, and the density of the insole body 1 is between the density of the heel layer 13 and the density of the forefoot layer 12.
[0031] Specifically, the heel layer 13 is made of high-density material: the heel is the first part of the foot to touch the ground during walking, and it bears a lot of impact force. High-density material can effectively absorb impact and reduce pressure on the ankle and knee.
[0032] High-density material disperses impact force, reduces peak pressure, and protects joints and soft tissues. The insole body 1 is made of medium-high density material: the arch is an important structure that supports the foot, and medium-high density material provides stable support to prevent the arch from collapsing or over-fatigue. By supporting the arch, reducing the stretching of the plantar fascia, optimizing the stress distribution of the foot, and avoiding problems such as plantar fasciitis. The forefoot layer 12 is made of medium-low density material: the forefoot bears a lot of pressure during the propulsion phase of walking, and medium-low density material provides moderate cushioning and elasticity to help push the body forward. By designing cushioning and elasticity, it reduces the concentration of pressure on the forefoot, improving the comfort and efficiency of walking. The toe layer 11 is made of low-density material: the toe area needs flexibility and comfort, and low-density material provides a soft touch to avoid squeezing and friction. Reducing local pressure in the toe area prevents blisters and discomfort.
[0033] In actual production of insoles, the toe layer 11 is made of 130 density PU. This density of PU material in insoles can provide better support and comfort. It is suitable for footwear that needs certain cushioning and support. Its density is moderate, providing enough elasticity without being too heavy. The advantages are as follows:
[0034] Comfort: PU material is soft, which can effectively reduce foot fatigue.
[0035] Durability: PU material is wear-resistant and has a long service life.
[0036] Breathability: Some PU materials are specially treated and have good breathability, suitable for long-term wear.
[0037] The forefoot layer 12 is made of 150 high-density PU. High-density PU material in insoles can provide stronger support and durability. It is commonly used in footwear that requires higher support and cushioning performance, such as sports shoes, hiking shoes, work shoes, etc. Its high-density characteristics make it suitable for long-term wear and high-intensity activities. The advantages are as follows:
[0038] High support: High-density PU material provides better support and reduces foot fatigue.
[0039] Durability: High-density PU material is more wear-resistant and has a longer service life.
[0040] Stability: High-density materials are not easily deformed during long-term use, maintaining the shape and function of the insole.
[0041] The heel layer 13 uses 200 ultra-high density PU. Ultra-high density PU material provides excellent support and durability in insoles. 200 high-density PU insole material is commonly used...
[0042] Used in footwear requiring extremely high support and cushioning, such as professional athletic shoes, hiking boots, and work shoes. Its ultra-high density characteristics...
[0043] This makes it suitable for prolonged wear and high-intensity activities. The advantages are as follows:
[0044] Ultra-high support: The ultra-high density PU material provides excellent support and reduces foot fatigue.
[0045] Durability: The ultra-high density PU material is more wear-resistant and has a longer service life.
[0046] Stability: The ultra-high density material is not easily deformed during long-term use, maintaining the shape and function of the insole.
[0047] The heel layer 13 can also be made of Poron. Poron is a high-performance polyurethane foam material with excellent cushioning, resilience, and durability. It is known for its high energy absorption and low compressive deformation properties, providing lasting comfort and support. It is particularly suitable for insoles requiring high cushioning and support. It is commonly used in medical and orthotic insoles to provide additional comfort and protection. Advantages include:
[0048] High cushioning: Poron material effectively absorbs impact and reduces foot fatigue.
[0049] Resilience: The material has good resilience and can quickly return to its original shape.
[0050] Durability: Poron material is wear-resistant and has a long service life.
[0051] Breathability: The material has good breathability and is suitable for long-term wear.
[0052] The insole body 1 is made of PU foam. PU foam (Polyurethane Foam) is a lightweight, soft and elastic material commonly used in insole manufacturing. Through special treatment, PU foam can have the functions of ventilation, antibacterial and odor resistance, improving wearing comfort and hygiene. The functional characteristics are as follows: Ventilation: PU foam material can promote air circulation through the open structure or add a breathable layer to reduce the hot and humid feeling of the feet.
[0053] Antibacterial property: By adding antibacterial agents or using antibacterial treatment technology, PU foam can effectively inhibit the growth of bacteria and reduce odor.
[0054] Odor resistance: Combined with ventilation and antibacterial properties, PU foam can effectively prevent foot odor and maintain a fresh insole environment.
[0055] The advantages of PU foam are as follows:
[0056] Comfort: Soft and elastic, providing good foot support and cushioning.
[0057] Hygiene: Antibacterial and odor-resistant functions help maintain foot health.
[0058] Durability: PU foam material is wear-resistant and has a long service life.
[0059] Further, the toe layer 11 is distributed transversely along the toes, and the toe layer 11 is provided with fingerprint lines 111. Among them, the fingerprint lines designed to echo the toes are shallow lines, which can reduce friction and extrusion.
[0060] Further, the forefoot layer 12 is distributed transversely along the forefoot, and the forefoot layer 12 is provided with horizontal and vertical interlaced lines 121 or / and bionic cartilage lines 122. The forefoot layer 12 can choose horizontal and vertical interlaced lines 121, bionic cartilage lines 122, or a combination of the two. Adopting horizontal and vertical interlaced lines and adding bionic cartilage pattern design can enhance the grip and propulsion.
[0061] Further, the heel layer 13 is provided with honeycomb lines 131 to enhance the cushioning and shock absorption effect.
[0062] Further, the insole body 1 as a whole is arched to support the arch of the foot. The arched support lines improve stability and fit.
[0063] By adapting to the natural structure of the human foot, the physiological characteristics of the arch, metatarsal and other parts are simulated to optimize the stress distribution.
[0064] Further, the front side of the insole body 1 is provided with a serrated notch 14 near the side of the big toe. The serrated notch 14 better fits the arch curve, enhances the support force on the medial arch, reduces foot sliding during exercise, and improves stability. The serrations on the edge of the notch can more closely engage with the insole or fixing glue, preventing the insole from shifting during use, especially for high-intensity sports scenarios. And by forming an air circulation channel, it promotes air circulation in the shoe, reduces the hot feeling of the feet, and improves comfort, especially when running or walking for a long time.
[0065] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement or improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
