The floor under competitors' feet for indoor sports like gymnastics may look rather ordinary, but in fact there are a lot of stories behind such appearances. If it is too flat, athletes will flip. Yet too much attraction is not good either. We will peel back the layers to look at the technology below for sports like basketball, gymnastics, beach volleyball and football.
