SAMEFOOT LUNGE

In closed position, the man steps side and slightly forward with the right foot, looking right. The woman steps back with her right ("samefoot") well under her body, head left. The supporting legs are flexed in a lunge. The left legs are straight and extended to the side for the man and forward and across for the woman.
A common "shaping" or "developing" of this picture figure is from closed position to semi-closed. The man stretches his right side and opens her head.
The cue might be, "samefoot lunge and slowly change sway."
