As has already been mentioned the slip jig dance always danced by a girl in light shoes - there is no heavy shoe version (heavy shoes make a noise). The jig and reel have both light and heavy versions (the steps are quite different) and there are also hornpipes and set dances like the Blackbird or Saint Patricks Day for example (both in heavy shoes). There is significant differences in the steps between the slip jig and the light double jig. I always enjoy watching the slip jig and personally I think it is the most graceful of all the Irish step dances.
