<P> The human foot has two longitudinal arches and a transverse arch maintained by the interlocking shapes of the foot bones , strong ligaments , and pulling muscles during activity . The slight mobility of these arches when weight is applied to and removed from the foot makes walking and running more economical in terms of energy . As can be examined in a footprint , the medial longitudinal arch curves above the ground . This arch stretches from the heel bone over the `` keystone '' ankle bone to the three medial metatarsals . In contrast , the lateral longitudinal arch is very low . With the cuboid serving as its keystone , it redistributes part of the weight to the calcaneus and the distal end of the fifth metatarsal . The two longitudinal arches serve as pillars for the transverse arch which run obliquely across the tarsometatarsal joints . Excessive strain on the tendons and ligaments of the feet can result in fallen arches or flat feet . </P>
