Parallel Ready Stance (Naranhi Chunbi Sogi) is one shoulder width wide as measured from the foot sword.  The feet are even and parallel.  The weight is distributed evenly with both legs being straight.  With the elbows partially bent and held 10 cm from the floating ribs and the fists slightly clenched and held 5 cm apart and held 7 cm from the abdomen, this is performed only full facing.

Walking Stance (Kon-Nun Sogi) is one shoulder width wide, measured between the center of the instep of each foot.  It is one and one half shoulder widths long, measured from the big toe of the rear foot to the big toe of the front foot.  The weight is distributed evenly between both feet.  The back leg is straight and locked with the back foot pointed out at a 25 degree angle.  The front leg is bent, with the kneecap directly over the heel.  The front foot is pointed straight forward.  This stance is performed either half facing or full facing.  This is also named after the front foot e.g. "right front walking stance."
