What is plantar fasciitis
Plantar fasciitis develops when the thick band of tissue under the foot (the plantar fascia) becomes inflamed from repeated strain over time. This tissue connects your heel to your toes and supports your arch.
The most common cause is overload, whenever we stand for a prolonged time the plantar fascia gets stretched causing micro tears to appear. When the body doesn't get enough time to repair these micro tears it eventually causes inflammation (plantar fasciitis). This often happens in people who stand for long hours, walk or run more than usual, or wear unsupportive shoes, especially on hard surfaces.
Plantar fasciitis is extremely common. More than 2 million people in the U.S. are treated for it each year. Around 1 in 10 people will develop plantar fasciitis at some point throughout their life.
