There is no specific age at which flatfoot is best treated, but the conventional wisdom is that the earlier the treatment, the better the results. Because the arch is more flexible during childhood, timely correction can allow the arch to be reshaped and can improve the complications of flat feet. In adults, the arches are already formed, and it is difficult to return to normal at this time, so surgery is often required. In childhood, especially in newborns and infants, if the arch is found to be collapsed and flattened, arch pads can be used to lift and prop up the arch, and the foot of infants and children will gradually develop and shape, and the situation of flat feet will slowly improve. If the flat foot needs to be corrected in adulthood, bony surgery is required to reshape the normal shape of the arch through osteotomy.
