Plantar Fascia (also known as plantar aponeurosis) is a strong fibrous band of tissue on the bottom of the foot. It extends from the heel bone (or to be precise the calcaneal tubercle) to the base of the toe bones (proximal phalanges).
Fascia is tissue mainly composed of collagen that occurs throughout the body in a variety of guises. There is fascia extending under the surface of the skin and lining the nuclei of cells. Fascia surrounds all muscles, bones and joints and is the substance referred to as 'silver skin' in meat. There is fascia encasing the viscera (vital organs) and brain, and it also lines arteries and blood vessels. The fascial network provides structure, protection, communication and a degree of movement throughout the body. Furthermore all fascia is innervated and is highly sensitive. In a way it is your body's world wide web, allowing information to feedback and feedforward in an instant. The plantar fascia therefore is key to our connection to the ground we walk on.
