Is it useful for children to correct insoles before answering questions? First of all, let's understand the harm of flat feet. In addition to long-term walking, children's flat feet can also cause foot pain. With the increase of age, the development of children's spine will also be affected. Pelvic tilt, scoliosis, high and low shoulders, etc. It is the "sequela" of flat feet. In terms of treatment, it is more effective and convenient to use corrective insoles, but the critical period of correction is 2- 14 years old, and then the effect will decline. As for German Codman insoles, I have learned about them before. Codman's orthotic foot pads are specially made for children according to their specific gait data, which is relatively scientific.
