street shoes. dress shoes

Someone asked me a question the other day that i was not sure how best to answer since I have very little experience with ladies shoes :)

She asked me if there was an inexpensive street shoe she could buy that would be good for dancing. Does such a thing exist in ladies footwear?

What attributes would you look for in a street shoe or a dress shoe that you might go dancing in?

Comment please!!
