Twinkle Toes 1978. I can say that on a Heel Turn, ( man does one on an Open Imputes ). Some ladies do not take the full beat value, that is two beats on their first step. What happens is the LF , if this a Reverse Turn Foxtrot starts to move too soon, it now has a good chance of passing the standing foot making a sloppy Heel Turn. As practice it is a good idea for both parties to music count 12 and don't move the free foot untill the end of the second beat. The other thing that is being taught, that on the first step turn the toe inwards slightly ( felt but not seen). And turn on one heel only. It is a Heel Turn and not a Heels Turn. Also don't over do it, but there is sway to the right on 2 as well as 3.
