[0001] The utility model relates to the technical field of insoles, in particular to a novel shock-absorbing insole. Background Art

[0002] An insole is a pad placed inside a shoe to provide extra comfort, cushioning, support, and protection to the foot. Insoles are usually made of a variety of materials such as sponge, gel, memory foam, etc. They can help reduce foot fatigue, absorb shock, adjust the size and shape of the shoe, and provide extra support and stability.

[0003] However, the existing insoles are mainly made of cloth and PU / EVA sponge. The insoles achieve shock absorption function through their own materials. The insoles have a simple structure and are easy to collapse when stepped on. After long-term wearing, the insoles are deformed. After wearing, they cannot form effective support for the arch of the foot, so that the distribution of plantar pressure is mainly concentrated on the forefoot and heel, which not only brings fatigue and pain to the foot, but also cannot provide better support and rebound effect for the plantar.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a new shock-absorbing insole includes an insole body 1, which includes a forefoot portion 10, an arch portion 11 and a heel portion 12 formed in sequence. The upper surface of the heel portion is depressed downward to form a recess so that the insole body 1 is consistent with the curvature of a person's foot, thereby stabilizing the heel.

[0031] Specifically, the insole body 1 includes a PU midsole 2, the surface of the PU midsole 2 is provided with a fabric layer 3, and the fabric layer 3 is made of breathable antibacterial fabric, which has antibacterial and sweat-absorbing effects; the bottom surface of the PU midsole 2 is provided with a TPU support body 4 for supporting the arch and heel, and the TPU support body 4 is provided with an air cushion spring assembly 5, and the bottom surface of the TPU support body 4 is provided with an arch groove 6 located in the arch. The TPU support body 4 makes the insole less likely to collapse and deform, and can provide a good supporting effect on the sole as a whole. The air cushion spring assembly 5 can play a role in rebound and shock absorption, which can make the wearer walk more easily, and the arch groove 6 is added to the TPU support body 4 to make it more stable as a whole and less likely to collapse, thereby reducing foot fatigue and pain.

[0032] In order to further increase the shock-absorbing effect of the insole, a shock-absorbing gasket 7 is provided on the bottom surface of the PU midsole 2 at the forefoot part.
