Planimetric analysis of footprints in 60 normal males and in 70 normal females was performed in order to study the effect of body weight on the configuration of the plantar arch. Individuals were subdivided according to the area of the sole of the foot, as well as according to body weight to study the ratio of the nonim printed portion to that of the imprinted portion of the sole of the foot. The ratio of these two values was expressed by the planimetric index, showing a rapid increase with increasing weight which is characteristic for the impairment of the shape of the plantar arch. Thus higher weight exerts an unfavorable effect on the shape of the plantar arch. Intersexual differences were not significant.
