The position at the start is as follows:
Man's left foot behind the right, left toe at the heel of the right, both toes
turned out—his partner's right foot in front of her left, her right heel at the
toe of her left foot, both toes turned out.
The man raises the left foot and at
the same time raises on the toe of the right, turn both toes in, twisting on
the ball of the right foot.
With the feet in this position, both toes are
twisted out, with the man's left heel in front of his right toe—his partner's right
heel in front at her left toe.
The man raises his left foot, at the same time rising on the ball of the
right foot, and twists both toes in, then puts his left foot behind the right
one, and on the balls of both feet twists both toes out—his left toe behind at
the right heel.
His partner raises her right foot, at the same time rising on
the ball of her left foot and twists both toes in, then puts her right foot in
front and on the balls of both feet turns both toes out—her right toe in front
at her left heel.
A toddle movement is taken through-out all the steps, on the
foot on which the weight happens to be.
