One need only think back to the Pet Rock to realize that anything can be sold to anyone who doesn't know any better. That hardly qualifies a product for endorsement. The need for dance floor wax usually is a result of wearing improper boots or shoes for dancing. For some reason, many dancers don't seem to consider dance floors in the same category as basketball courts and would be outraged to be forced to buy 'special' shoes for dancing. It's a shame.
Dance shoes are light-weight and comfortable.
They need extra care to keep the chrome suede sole effective but they do smooth out the differences between floors in different states of repair and care. I personally stay off of floors that have been sabotaged like this. But then, I'm not into lawsuits. Don't risk your financial future betting that everyone comes from this point of view. Wear proper footwear and you too can spin like a top and dance like you want to, without endangering others.
