Sole of foot

Definition and stakes

Dorothy Furniss Drawing For Beginners (1920)

If we want to see the foot unspoiled then we must go to the countries where fashion and manners have not affected it, where generation after generation has walked the earth on the bare foot, or with only the slightest protection of a sandalled sole. Then we see how finely it supports the body, what a thing of strength and beauty it can be!—firm heel, arched instep, springing muscles of the sole imprinting the ground with its firm tread!

John Lord Peck Dress and care of the feet (1872)

The great toe plays by far the most important part in walking, because when the foot is raised from the ground, with the intention of throwing it forward, we first raise the heel, then rest for a second on the great toe, and in lifting this from the ground the point of it receives a pressure which impels the body forward. Thus, in raising the foot, the whole of the sole is gradually, as it were, ‘unrolled,’ up to the point of the great toe, which again receives an impetus by contact with the ground.

The heel strikes the ground with great force, as the wear of our boots and shoes in that part shows us. But the projecting heel of the human foot is the arm of a lever, haying the ankle-joint as its fulcrum, and, as it strikes the ground, brings the sole of the foot down flat upon it, as shown in figure 1. At the same time the weight of the limb and body is thrown upon the foot, by the joint effect of muscular action and acquired velocity, and the other foot is now ready to rise from the ground and repeat the process we have traced in its fellow.
