The plantar (foot) fascia (connective tissue) stretches under the skin across the arch of the
foot from the heel to the base of the toes. When this tissue is torn, overused,or
improperly stretched, it can become inflamed (fasciitis). Soreness, tenderness, and pain result. Persons who are overweight,
female, or older than 40 years or who spendlong hours on their feet are especially
at risk of developing plantar fasciitis. Athletes, especially joggers and
runners, may develop plantar fasciitis.
