Represents a vertical transverse section of the ball portion of a boot from the Patent Last, showing S, (the sole,) convex on its upper and flat on its under surface. Elevation F, fig. 8, affords uniform support to this portion of the sole of the foot, and prevents lateral gliding motion and treading out or inwards of the foot; important to the even and economical wearing of the boot.
