We performed a prospective study to determine whether flexible flatfoot in children can be influenced by treatment. One hundred and twenty-nine children who had been referred by pediatricians, and for whom the radiographic findings met the criteria for flatfoot, were randomly assigned to one of four groups: group I, controls; group II, treatment with corrective orthopaedic shoes; group III, treatment with a Helfet heel-cup; or group IV, treatment with a custom-molded plastic insert. All of the patients in groups II, III, and IV had a minimum of three years of treatment, and ninety-eight patients whose compliance with the protocol was documented completed the study. Analysis of radiographs before treatment and at the most recent follow-up demonstrated a significant improvement in all groups (p < 0.01), including the controls, and no significant difference between the controls and the treated patients (p > 0.4). We concluded that wearing corrective shoes or inserts for three years does not influence the course of flexible flatfoot in children.
