The ankle on the right is an example of rolling in.

Rolling Dancers who do not have a good turn-out should not force their legs to turn out too much at first, as this usually results in rolling ankles. If the weight is on the inside of the feet. dancers call this rolling in; if the weight is on the outside of the feet, it is called rolling out. The toes and heels should be flat on the floor and the turn-out must come from the hip joints.
