Anterior leg muscles All muscles originating on the lower leg except the popliteus muscle are attached to the bones of the foot. The tibia and fibula and the interosseous membrane separate these muscles into anterior and posterior groups, hinein their turn subdivided into subgroups and layers.[6]
The United States is the only industrialized country that uses the (international) foot rein preference to the meter hinein its commercial, engineering, and standards activities.[4] The foot is legally recognized rein the United Kingdom; road distance signs must use imperial units (however, distances on road signs are always marked hinein miles or yards, not feet; bridge clearances are given rein meters as well as feet and inches), while its usage is widespread among the British public as a measurement of height.

The date of December 31, 2022, welches selected to accompany the modernization of the Landesweit Spatial Reference Anlage (NSRS) by NOAA's Landesweit Geodetic Survey (NGS). The reason for associating the deprecation of the U.S. survey foot with the modernization of the NSRS is that the biggest impact of the Gleichförmig adoption of the international foot will be for users of the NSRS, due to very large coordinate values currently given in U.

A doctor Weltgesundheitsorganisation specializes rein the treatment of the feet practices podiatry and is called a podiatrist. A pedorthist specializes in the use and modification of footwear to treat problems related to the lower limbs.
The flexor hallucis longus arises on the back of the fibula on the lateral side, and its relatively thick muscle belly extends distally down to the flexor retinaculum where it passes over to the medial side to stretch across the sole to the distal phalanx of the first digit. The popliteus is also part of this group, but, with its oblique course across the back of the knee, does not act on the foot.[10]
This leaves humans more vulnerable to medical problems that are caused by poor leg and foot alignments. Also, the wearing of shoes, sneakers and boots can impede proper alignment and movement within the ankle and foot.

An individual Weltgesundheitsorganisation neutrally pronates initially strikes the ground on the lateral side of the heel. As the individual transfers weight from the heel to the metatarsus, the foot will roll rein a medial direction, such that the weight is distributed evenly across the metatarsus. Rein this stage of the gait, the knee will generally, but not always, track directly over the hallux.

The plantaris originates on the femur proximal to the lateral head of the gastrocnemius and its long tendon is embedded medially into the Achilles tendon. The triceps surae is the primary plantar flexor. Its strength becomes most obvious during ballet dancing. It is fully activated only with the knee extended, because the gastrocnemius is shortened during flexion of the knee. During walking it not only lifts the heel, but also flexes the knee, assisted by the plantaris.[9]
In addition, there are several genetic disorders that can affect the shape and function of the feet, including clubfoot or flat feet.
