The feet assume the burden of supporting and balancing the body while a person stands, walks and exercises. Therefore, the physical condition of a person is closely related to the health of the feet. However, the pain of walking away is difficult to endure due to the congenital flat feet; the hallux is easy to turn outwards after long-time wearing of the high-heeled shoes, and has adverse effect on toes; the splayed walking shoes have serious partial abrasion of soles, so that walking is easy to be tired, and the like. Especially, if children often yell "tired of feet", "uncomfortable feet", do not want to do much exercise, or have abnormal foot arches, parents should pay attention to the fact. Over time, these poor foot dysfunction and mismatched lower limb mechanics can cause the human foot to have asymmetric upper skeletal system symmetry and to deviate from neutral position. If the foot soles are not corrected in time, the serious condition even causes the unbalance of the body mechanics of the whole body, and the physical and psychological health is influenced.

Therefore, in order to meet the requirements of different users, the shoe pad with personalized design shows huge market prospect and use advantages. The existing method for manufacturing the personalized insole by utilizing Fused Deposition Modeling (FDM) according to the three-dimensional model has poor manufacturing precision and speed and unsatisfactory insole correction effect.
No effective solution has been proposed to the above problems.

In another alternative embodiment, the support member of the insole is at least one of the following materials: thermoplastic polyurethane elastomer high polymer material and polydodecalactam high polymer material.
In the embodiment of the invention, the thermoplastic polyurethane elastomer high polymer material (TPU) has the characteristics of excellent high tension, high tensile force, toughness and aging resistance, and is a mature environment-friendly material. At present, TPU is widely applied to medical and health care, electronic and electric appliances, industry, sports and the like.

In the embodiment of the present invention, the polydodecalactam polymer material, commonly called nylon, is also called PA6 or PA 12. PA12 was chosen as the material for SLS forming because PA12 has good impact resistance and chemical stability, as well as many improvements in plasticizing and reinforcing properties. Compared with PA6 and PA66, the materials have lower melting point and density and very high moisture regain, so that the materials are very suitable for SLS forming.
In an alternative embodiment, after the insole body is manufactured based on the shoe size information, the method of manufacturing the insole further comprises:
and step S110, jointing the insole body and the supporting component by the jointing device according to a physical jointing method to obtain the insole.
