Pronation is a normal, desirable, and necessary component of the gait cycle. [4] Pronation is the first half of the stance phase, whereas supination starts the propulsive phase as the heel begins to lift off the ground.

Pronation at the forearm is a rotational movement where the hand and upper arm are turned so the thumbs point towards the body. When the forearm and hand are supinated, the thumbs point away from the body. Pronation of the foot is turning of the sole outwards, so that weight is borne on the medial part of the foot. [33]
The foot (pl.: feet) is an anatomical structure found in many vertebrates.It is the terminal portion of a limb which bears weight and allows locomotion.In many animals with feet, the foot is a separate [clarification needed] organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
The foot provides the sensory information to the central nervous system through cutaneous afferent feedback, which originates from the special mechanoreceptors within the plantar surface of the foot. This afferent feedback has a strong influence on postural stability [ 1 ] and balance correction [ 2 ] during standing and walking.
Plantigrade foot occurs normally in humans in static postures of standing and sitting. It should also occur normally in gait (walking). Hypertonicity , spasticity , clonus , limited range of motion, abnormal flexion neural pattern, and a plantar flexor (calf) muscle contracture, as well as some forms of footwear such as high heeled shoes may ...
The axis of rotation in the joint is directed upward 42 degrees from the horizontal plane and 16 degrees medially from the midline of the foot. However, together, the subtalar facets form a screw or Archimedean spiral (right-handed in the right foot) about which subtalar motion occurs. So, during subtalar inversion, the calcaneus also rotates ...

The foot structures are divided into segments from proximal to distal and are grouped according to similarity in shape, dimension and function. In this approach, the foot may be described in three segments: as the hindfoot, midfoot and forefoot. The hindfoot is the most proximal and posterior portion of the foot. [22]
