To do the Cambiata de Piedi strisciata: Beginning with the left foot behind, in passo naturale, as seen in the figure, do as in Rule 3, noting that in the jump up, you ought not otherwise lift yourself from the ground, but raise your body a little, and in thrusting forward the left, and drawing back the right, slide your toes on the ground, and then stop with the left foot forwards, in passo naturale. And this can also be done on the other side, and and it is so called because you exchange feet, and slide your toes on the ground.
