Where I train table tennis, the floor is a typical school gym floor, which is also slightly slippery, as it is quite dusty. I played a national tt tournament this weekend in a basketball hall, and the floor there was very grippy, almost sticky, and it felt like it was dampened. You could feel how you sink in a small bit. It was very hard for me to get my footwork to work properly (not only for me, but for everyone else from my club). Balls that were played in my wide forehand were impossible to hit, as I was always standing incorrectly due to my slower footwork. Does anybody else have experience with those kind of conditions?
