these shoes are excellent for Zumba classes, of which I take three a week.  They are light and the soles allow easy lateral moves without torque on the knees - a major improvement over regular gym shoes.  They offer little if any support, but that is not a drawback in a dance sneak...no one would wear it anywhere else, or for any other form of exercise, anyhow.  the only drawback, and this may be unavoidable, is that my feet do slip during lunge stretches after class.
