Plantar fascia - Definition

Ask a question


Fascia is defined as a tough, white membrane which envelops the muscles. Plantar fascia is a fibrous tissue of the foot situated beneath the skin, in the middle of the arch of the foot and connected to the heel and to the first toes. This plantar fascia keeps the arch of the foot tense. It supplies the strength necessary to move the foot forward. Plantar fascia also plays a role in the stability of the arch while walking. The shorter the fascia is, the higher the arch will be. On the other hand, when the fascia is long, the feet are flat.
