Dania Kaseeva has wowed audiences all over the world with her hula hoop artistry while encouraging young performers to follow in her footsteps. How does she do it so effortlessly? Aluminum hoops respond better to the inertia in comparison to plastic hoops that tend to warp, losing a lot of the inertia or energy. Therefore it takes less effort to "hoop" with aluminum hoops. These hoops have a 36" diameter, are SUPER LIGHT at just over 6 ounces a piece and come with either a shiny finish or a highly polished finish for the professional performer.
