Like I said, play football or rugby or ultimate frisbee (if your that type) barefoot. You can roll your ankle barefoot with a sudden stop or change in direction or landing wrong, all those things can happen playing tennis.
Minimus are the new NB minimalist shoes, nice for running BAAAD for tennis. CC Rides I wouldn't put in the minimalist category, they are very light and low but still a bit higher than say the Minimus. The Charge RC is UA's flagship shoe, they looked sick so I bought them and they are crazy smooth rides. I'll say it again, it you just bat the ball around wear whatever the hell you want, if your a serious player get the right equipment. There's a reason, other than cash, why pros and good college players use purpose built tennis shoes.
