The column of the thigh and leg diminishes in thickness as it descends to the foot. From any view it also has a reverse curve that extends its entire length.

On either side a descending wedge overlaps the rounded form of the thighs and this again overlaps the square form above and below the knee joint, which is also square. The leg at the calf is triangular; at the ankle it is square.
