Had our regular league match tonight, and as I am getting ready to serve, my partner is pulling fuzz out of his shoes. My shoes had a fair bit as well. A few weeks ago, I had brought some treats for Christmas to my coach's junior program, as they let me hit in with them from time to time. The owner was on my case about not dropping crumbs, but when I asked him about the fuzz level, he said "this is nothing." Asking around I have yet to figure out how often the fuzz gets cleaned up. But it makes me wonder how often other places clean up.
