Although the plantar fascia is made to absorb the shock and pressure we place on our feet, too much pressure can cause inflammation.
Active persons and younger persons are more likely to develop plantar fasciitis. Women are slightly more at risk than men. Some pregnant women might experience this condition during late pregnancy.
Obesity (overweight) is a risk factor for plantar fasciitis. Having too much weight places pressure on the ligament.
Runners are also at risk of developing plantar fasciitis, especially long-distance runners. Jobs or activities that require you to be up, on your feet, such as serving in a restaurant, or working in a factory also contribute.
Other contributing factors are having a high arch, flat feet, or tighter calf muscles.
