The plantar fascia is a thick band of tissue that connects your heel bone to your toes. It helps support the overall shape of your foot, especially when standing. Irritation and scarring of the plantar fascia, known as plantar fasciitis, is one of the most common causes of heel pain.
Often there is no one event that triggers heel pain. It generally develops over time and can become extremely painful, especially with the first few steps in the morning. It is more common in women, those who walk a lot and people who are overweight. Risk factors include your natural foot shape (flat or high arch), your activities (walking, running) and improper shoes.
