The human foot, considered in its entirety, is indeed a very wonderful anatomic part of the individual. In the smallness of its size and weight, out of all proportion to the burden borne and carried, it constitutes a mobile, strong, flexible and efficient member of the organism designed to bear weight forwards, backward, and sideways without mishap. Encased in a cloth covering, the sock, and in a protective leather covering, the shoe, both concomitants of an advancing and exacting civilization, this member, the most unintentionally neglected part of the body is fully expected to do its duty indefinitely without complaint. As with other mechanisms, mechanical or otherwise, so with this, ignorance cannot accomplish satisfactory results.


Concisely, the structure of the foot is composed of a nicely adjusted aggregation of twenty-six bones of various sizes and


The longitudinal arch, on the inner side of the foot, extends from the heel bone (Os Calcis) to the distal end of the first

metatarsal bone. (Sec illustration No. 2.) This is definitely formed by the inherent structural concavity of the bones held among themselves by ligaments and supported from below by developed muscle layers. The anterior arch is formed by the distal ends of the meta.. tarsal bones. (See illustration No. 5.) The muscular development concerned in sustaining this arch is not so great as in the longitudinal.

A tripod is formed by the structure of the foot; the apex of which is the highest point of the heel bone (Os Calais), the inner side of the ball of the foot at the base of the big toe (distal end of first metatarsal bone) and the outer side of the ball of the foot at the base of the little toe (distal end of the fifth metatarsal bone).
