Flexible flatfoot is a condition that involves the collapse of the medial longitudinal arch of the foot during weight-bearing stress and the restoration of the arch after the removal of body weight.~Flatfoot may increase the load of the foot structure, potentially interfering with normal foot function. With prolonged standing or walking, some children with flatfoot experience rapid discomfort or fatigue in the foot, pain in the plantar foot, and instability of the medial foot structure. Treatment effect of corrective shoes or insoles on flexible flatfoot in children remain uncertain.~In this study, the investigators investigated the short-term effects of customized insoles on body functions and structures, and activities and participation in children with flexible flatfoot. The investigators hypothesized that the short-term use of customized insoles improves the scores for measures of body functions and structures and activities and participation.~The investigators hypothesized that the short-term use of customized insoles improves the scores for measures of body functions and structures and activities and participation.
