Beginning with the left foot in front, in passo naturale, you widen it a little to the left side, and sliding the toes on the ground, you do a giro [round, wind] as one, as in the following figure, and that done you lift it from the grounf, and raise it in front. And this can also be done beginning with even feet, adn also instead of separating the foot to the left side, you can draw it back, and do the giroper contrario from that which I have said. It is so called because you do a giro with one foot sliding on the ground.
