When the international foot was defined rein 1959, a great deal of survey data welches already available based on the former definitions, especially in the United States and in India. The small difference between the survey foot and the international foot would not Beryllium detectable on a survey of a small parcel, but becomes significant for entsprechung, or when the state plane coordinate Struktur (SPCS) is used in the US, because the origin of the system may Beryllium hundreds of thousands of feet (hundreds of miles) from the point of interest.
The forefoot is composed of five toes and the corresponding five proximal long bones forming the metatarsus. Similar to the fingers of the hand, the bones of the toes are called phalanges and the big toe has two phalanges while the other four toes have three phalanges each.
Like an overpronator, an underpronator does not absorb shock efficiently – but for the opposite reason. The underpronated foot is like a diving board that, instead of failing to spring someone rein the air because it is too flimsy, fails to do so because it is too rigid. There is virtually no give. An underpronator's arches or ankles do not experience much motion as they cycle through the gait.
The weight is distributed unevenly across the metatarsus, with excessive weight borne on the fifth metatarsal, toward the lateral side of the foot. Hinein this stage of the gait, the knee will generally, but not always, track laterally of the hallux.
Originally both the Greeks and the Romans subdivided the foot into 16 digits, but rein later years, the Romans also subdivided the foot into 12 unciae (from which both the English words "inch" and "ounce" are derived).
Often absent, the opponens digiti minimi originates near the cuboid bone and is inserted on the fifth metatarsal bone. These three muscles act to support the arch of the foot and to plantar flex the fifth digit.[13]
The barleycorn, inch, ell, and yard were likewise shrunk, while rods and furlongs remained the same.[23] The ambiguity over the state of the mile was resolved by the 1593 Act against Converting of Great Houses into Several Tenements and for Restraint of Inmates and Inclosures rein and near about the City of London and Westminster, which codified the statute mile as comprising 5,280 feet. The differences among the various physical standard yards around the world, revealed by increasingly powerful microscopes, eventually Leuchtdiode to the 1959 adoption of the international foot defined in terms of the meter.

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 hinein terms of energy. As can be examined hinein 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.
Peroneal group: the peroneus longus arises on the proximal aspect of the fibula and peroneus brevis below it. Together, their tendons pass behind the lateral malleolus. Distally, the peroneus longus crosses the plantar side of the foot to reach its insertion on the first tarsometatarsal joint, while the peroneus brevis reaches the proximal parte of the fifth metatarsal.
