[0002] Flat feet is a relatively common foot disease, with an incidence rate of 7.1% of the population. Among adults with flat feet, more women over 50 years old have it. In fact, people with flat feet are very common, but flatfoot syndrome is not common. In addition, flat feet can occur in any season and region. Some patients with flat feet do not have obvious symptoms. They experience foot pain after walking for a long distance, which is relieved after rest. If it develops further, it mainly manifests as abnormal gait, pain in the feet and ankles, swelling and other symptoms. It can be congenital flat feet, or acquired flat feet due to certain factors. Flat feet can also cause some complications, such as tendinitis, plantar fasciitis, low back pain and other symptoms.

[0003] A feasible correction method is to use flat foot correction shoes to gradually correct the patient's flat arch, alleviate symptoms and relieve pain. The prior art mainly includes: flat foot insoles, such as Chinese patent CN202536256U, including reinforcement pads and sponge strips; located at the little toe of the insole, the reinforcement pad body is L-shaped, and the lower part is connected to the insole. The sponge strip is a soft sponge located at the center of the insole. The existing flat foot correction structure also has the following disadvantages: because the orthopedic insole is an integral structure, it cannot be changed according to the correction course, so it needs to be constantly customized according to the correction situation.
