By the direction of the foot-axis—that is, an imaginary line passing through the long axis of the three phalangeal bones ([Figs. 61], [65], [67], [68] and [69])—we determine whether or not the hoof and pastern stand in proper mutual relation.

A pair of front feet of regular position viewed from in front and from behind.
In the regular standing position ([Figs. 61] and [62]) the foot-axis runs straight downward and forward, in the base-wide position ([Figs. 63] and [64]) it runs obliquely downward and outward, and in the base-narrow position ([Figs. 65] and [66]) it runs obliquely downward and inward.
