Passo finto inanzi, and del strisciato (Santucci)

With the left foot behind in passo naturale you thrust it forwards by the right in a straight line, and without putting it on the ground draw it back in the same way as it was thrust forwards, and put it down in the place where you lifted it up. If you want to do it strisciato, instead of carrying it through the air, you slide it along the ground, both in thrusting it forwards and in drawing it back. It is so called because you pretend to go forwards, and return to the back, and you slide.
