Plantar fasciitis is a painful inflammatory condition caused by excessive wear to the plantar fascia of the foot, or biomechanical faults that cause abnormal pronation of the foot. The pain usually is felt on the underside of the heel, and is often most intense with the first steps of the day. It is commonly associated with long periods of weight bearing or sudden changes in weight bearing activity. Obesity, weight gain, jobs that require a lot of walking on hard surfaces, shoes with little or no arch support, and inactivity are also associated with the condition.
