Arches of the foot

arches of the foot

the three arches (two longitudinal and one transverse) are responsible for maintaining the optimum load-bearing position of the foot and thus walking motion. In the erect position, the arches are maintained primarily by the bones and ligaments, allowing even distribution of body weight. Abnormal foot biomechanics may result in alteration of this balance of load, causing discomfort.
