I just wanted to find out a couple of things about the ZM9T before I went ahead and bought a pair. Firstly, Im a fast and powerful mover on the court and have previously been a fan of the courtballistecs and barricades due to their impressive stability. Does the ZM9T offer good stability? As I really do not want to roll an ankle. Ive heard stories about the vapor tipping over and I want to find out if this really is the case. I would also like to know about the sizing. I wear a size 12 US in the courtballistec 3.3 and a size 11.5 US in the barricade 7. Does anybody have any recommendations on what size I should get in the vapor 9 tour? Much thanks for any advice.
