Hinein the deep layer of posterior muscles, the tibialis posterior arises proximally on the back of the interosseous membrane and adjoining bones, and divides into two parts in the sole of the foot to attach to the tarsus. Hinein the non-weight-bearing leg, it produces plantar flexion and supination, and, in the weight-bearing leg, it proximates the heel to the calf.

The metatarsal bones of feet and paws are tightly grouped compared to, most notably, the human hand where the thumb metacarpal diverges from the rest of the metacarpus.[21]

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.

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).

A doctor who specializes hinein the treatment of the feet practices podiatry and is called a podiatrist. A pedorthist specializes hinein the use and modification of footwear to treat problems related to the lower limbs.

An individual whose bone structure involves external rotation at the hip, knee, or ankle will Beryllium more likely to overpronate than one whose bone structure has internal rotation or central alignment. An individual Weltgesundheitsorganisation overpronates tends to wear down their running shoes on the medial (inside) side of the shoe toward the toe area.[17]

Extensor group: the tibialis anterior originates on the proximal half of the tibia and the interosseous membrane and is inserted check here near the tarsometatarsal joint of the first digit. Hinein the non-weight-bearing leg, the tibialis anterior dorsiflexes the foot and lift its medial edge (supination). Hinein the weight-bearing leg, it brings the leg toward the back of the foot, like in rapid walking. The extensor digitorum longus arises on the lateral tibial condyle and along the fibula, and is inserted on the second to fifth digits and proximally on the fifth metatarsal.

The adductor hallucis is part of this group, though it originally formed a separate Organisation (Teich contrahens). It has two heads, the oblique head originating obliquely across the central part of the midfoot, and the transverse head originating near the metatarsophalangeal joints of digits five to three. Both heads are inserted into the lateral sesamoid bone of the first digit. The adductor hallucis acts as a tensor of the plantar arches and also adducts the big toe and might plantar flex the proximal phalanx.[12]

Rein measurement, the term "linear foot" (sometimes incorrectly referred to as "lineal foot") refers to the number of feet rein a length of material (such as lumber or fabric) without regard to the width; it is used to distinguish from surface area in square foot.[60]

Muscles of the big toe: the abductor hallucis stretches medially along the border of the sole, from the calcaneus to the first digit. Below its tendon, the tendons of the long flexors pass through the tarsal canal. The abductor hallucis is an abductor and a weak flexor, and also helps maintain the arch of the foot. The flexor hallucis brevis arises on the medial cuneiform bone and related ligaments and tendons. An important plantar flexor, it is crucial to ballet dancing. Both these muscles are inserted with two heads proximally and distally to the first metatarsophalangeal joint.

In addition, there are several genetic disorders that can affect the shape and function of the feet, including clubfoot or flat feet.
