Plantar fasciitis or plantar heel pain is a disorder of the plantar fascia, which is the connective tissue that supports the arch of the foot. [2] It results in pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest.
The sole and the longitudinal arches of the foot are supported by a thick connective tissue, the plantar fascia. The central component of this tissue extends to the supporting bones and gives two divisions–the medial component and lateral component ; thus they define the boundaries of the three muscle compartments of the sole (see below).
Standing places significant pressure on the joint of the hips, knees, ankle and feet but without any significant movement of it. [9] This reduces the normal lubrication and cushioning of synovial joints, causing them to tear. The combined effect of pressure and tearing can cause extensive amounts of pain and make it difficult to move or walk. [3]

Orthostatic intolerance occurs in humans because standing upright is a fundamental stressor, so requires rapid and effective circulatory and neurologic compensations to maintain blood pressure, cerebral blood flow, and consciousness. When a human stands, about 750 ml of thoracic blood are abruptly translocated downward.
However minimal shoes do not give runners the same feedback from the plantar mechanoreceptors. Because of the greater protection they offer in comparison to barefoot running, minimal shoes may also interfere with the development of a gentle foot strike, toughening of the soles of the feet, and awareness of road hazards.
Standing desks and other innovations have made standing a popular antidote to extended periods of sitting. Unfortunately, standing may not be enough to offset those risks, according to new research.
Normally, a callus will form on any part of the skin exposed to excess friction over a long period of time. Activities that are known for causing calluses include (but are not limited to) construction work and craftwork, the arts, [3] food preparation, many sports and physical activities, [4] [5] and fashion choices like wearing high heels.
