Romeo

Well, Romeo the R'n'B singer is definitely a lightweight in the dancing department.
You can tell because I forgot him.
Light on your feet is not actually what a dancer wants. I think of one lady who flitted about, never putting down her heel even when I got down on my knees and begged her.
Force from the feet sends a dancer to the next step, affecting the body according to the style requested, with a swing of the hips for the smooth dances, taking the weight on to keep the flow traveling along. In the rhythm dances, that foot pressure moving up to the hip is stopped, making the Latin torso action.
