Occurs when the man has stopped the lady with foot contact and leads her to step forward over his extended foot. Used frequently at the end of molinete or after a mordida. The lady may, at her discretion, step over the man's foot or trace her toe on the floor around its front. Pasada provides the most common opportunity for the lady to add adornos or firuletes of her own and a considerate leader will give the lady time to perform if she wishes.
