I have a pair of Vapors and some CB 3.3's
but I still mostly play in my Nike Air Max's
As far as rolling ankles....everyone I personally know that has that injury all had the same thing in common.
(Top Heavy) either Slinging their beer gut around on court or a few that only spend time on the upper body at the Gym.
I am of even build and playing hockey for years leading up to tennis I'd say my lower body is stronger than my upper body.
I like to get to net quickly and in my air maxes I seem to do it better than in my "tennis shoes"
Throw some good insoles in them and my legs/feet/knees last way longer than my arm does.
