What is "sole"?

The sole refers to the underside or bottom surface of the foot. It is the part of the foot that comes into contact with the ground during standing, walking, and running. The sole is characterized by a thick layer of skin, called the plantar skin, which is designed to withstand pressure and friction. It contains various sensory receptors that provide feedback for balance, proprioception, and tactile sensations. The sole also houses the plantar fascia, a connective tissue that supports the arch of the foot. Understanding the anatomy and function of the sole is important for maintaining proper foot health, stability, and efficient locomotion.
