The term arch pain (often referred to as arch strain) refers to an inflammation and/or burning sensation at the arch of the foot. The plantar fascia is a broad band of fibrous tissue located along the bottom surface of the foot, that runs from the heel to the forefoot. Plantar fasciitis is caused by excessive stretching of the plantar fascia, usually due to over-pronation (flat feet).

The inflammation caused by the plantar fascia being stretched away from the heel, often leads to pain in the heel and arch areas. The pain is often extreme in the morning when an individual first gets out of bed or after a prolonged period of rest.The primary cause of an arch pain is over pronation. This can be controlled via sports insoles. People suffering with arch pain whom have been forced to live with the pain no longer have to put up with this condition while standing, walking or running.
