Little toe taps: Rhythmic tapping done with a flat foot on the ball or underside of the toe as an adorno.
(from batango.com (http://www.batango.com/Loomis.htm))
These are done with a level, not a tilted foot, so that the tap is done with the ball of your foot or the underside of your toes. The tap can be hard enough to make a click or so soft it barely kisses the floor. And, unlike golpes, you can do golpecitos walking backward as well as forward.
