Risk factors

Even though plantar fasciitis can develop without an obvious cause, some factors can increase your risk of developing this condition. They include:

• Age. Plantar fasciitis is most common between the ages of 40 and 60.
• Certain types of exercise. Activities that place a lot of stress on your heel and attached tissue — such as long-distance running, ballet dancing and aerobic dance — can contribute to the onset of plantar fasciitis.
• Foot mechanics. Flat feet, a high arch or even an abnormal pattern of walking can affect the way weight is distributed when you're standing and can put added stress on the plantar fascia.
• Obesity. Excess pounds put extra stress on your plantar fascia.
• Occupations that keep you on your feet. Factory workers, teachers and others who spend most of their work hours walking or standing on hard surfaces can damage the plantar fascia.
