DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer toFigures 1-4 The utility model discloses a kind of pressure-reducing insoles, including insole body 1, the vamp of insole body 1 is separately provided with heel support area 2, arch support area 3 and metatarsal support area 4, granular filler 103 is filled in heel support area 2, arch support area 3 and metatarsal support area 4, by filling the above-mentioned three areas, the heel part of human foot, arch part and metatarsal part can be supported and decompressed, can be shaped with the movement of foot part naturally, fit three area curves, reach the additional support and comfortable feeling of fitting human foot palm, granular filler 103 is any one of coconut shell activated carbon, buckwheat shell, so that insole has certain antibacterial odor removal effect;

[0022] The insole body 1 includes a TPU bottom layer 101, a TPU support layer 102, a granular filler 103, and a breathable fabric layer 104. The TPU support layer 102 is bonded to the TPU bottom layer 101. The breathable fabric layer 104 is bonded to the TPU support layer 102. Cavities 105 are provided on the TPU bottom layer 101 and the TPU support layer 102, and correspond to the positions of the heel support area 2, the arch support area 3, and the metatarsal support area 4. The granular filler 103 is filled in the cavities 105. Vent holes 106 are provided on the cavities 105 of the TPU support layer 102.

[0023] Specifically, a phalanx protruding part 5 is provided on the vamp of the insole body 1, and the phalanx protruding part 5 is arranged on the TPU support layer 102.

[0024] In this embodiment, the phalanx protruding part 5 provides additional support, which helps to reduce fatigue and pain in the foot.

[0025] Specifically, a convex point 6 is provided on the sole surface of the insole body 1, and the convex point 6 is arranged on the TPU bottom layer 101.

[0026] In this embodiment, the convex point 6 has a certain buffering and damping effect, which helps to reduce the pressure in the area.

[0027] Specifically, a concave edge 107 is provided at the edge of the TPU bottom layer 101, and a convex edge 108 is provided at the edge of the TPU support layer 102. The convex edge 108 and the concave edge 107 are engaged with each other.

[0028] In this embodiment, the engagement between the convex edge 108 and the concave edge 107 makes the connection between the TPU support layer 102 and the TPU bottom layer 101 more secure.

[0029] Specifically, the concave edge 107 is arranged in a closed loop on the upper surface of the TPU bottom layer 101, and the convex edge 108 is arranged in a closed loop on the lower surface of the TPU support layer 102.

[0030] In this embodiment, the positions of the concave edge 107 and the convex edge 108 need to match each other, mainly to ensure the close joint between the TPU support layer 102 and the TPU bottom layer 101.

[0031] Specifically, the cavities 105 on the TPU bottom layer 101 and the TPU support layer 102 penetrate each other and the positions of the cavities 105 match each other.

[0032] In this embodiment, the cavities 105 are used to provide space for filling the granular filler 103.

[0033] Specifically, the granular filler 103 is any one of coconut shell activated carbon and buckwheat shell.

[0034] In this embodiment, when the granular filler 103 is coconut shell activated carbon, the coconut shell activated carbon with granular structure has a certain fluffiness and can naturally shape with the movement of the foot. Through its developed pore structure and strong adsorption capacity, it can adsorb harmful gases and odors in the air, and the microporous structure can capture microorganisms such as bacteria and viruses and fix them in the pore channel, thereby reducing their number in the environment and playing a certain antibacterial role. When the granular filler 103 is buckwheat shell, the buckwheat shell with granular structure has a certain fluffiness and can naturally shape with the movement of the foot. The surface of the buckwheat shell contains natural antibacterial ingredients (such as flavonoids), which have a certain inhibitory effect on common bacteria such as Staphylococcus aureus. Its dry and breathable characteristics can also reduce the breeding of mites, making it suitable for people with allergies.

[0035] In use, the granular filler 103 is filled in the heel support area 2, the arch support area 3 and the metatarsal support area 4. By filling the above three areas, the heel, arch and metatarsal of the human foot can be supported and decompressed, and can naturally shape with the movement of the foot, fit the curve of the three areas, and achieve the fit of the human foot to provide additional support and comfort. The granular filler 103 is any one of coconut shell activated carbon and buckwheat shell, so that the insole has a certain antibacterial and odor removal effect.

[0036] In use, the granular filler 103 is filled in the heel support area 2, the arch support area 3 and the metatarsal support area 4. By filling the above three areas, the heel, arch and metatarsal of the human foot can be supported and decompressed, and can naturally shape with the movement of the foot, fit the curve of the three areas, and achieve the fit of the human foot to provide additional support and comfort. The granular filler 103 is any one of coconut shell activated carbon and buckwheat shell, so that the insole has a certain antibacterial and odor removal effect.

[0037] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
