My Metcon1 has better traction on dusty court than the Kobexi but I can't say the same for clean court.
On clean court the Kobexi grips like a v****!! but as soon as it gets a bit of dust on the bottom it turns into a new pair of dress shoes on old carpet.
With that being said.. still gonna...
I think most people are expecting the grip performance to be better/improved from the previous versions.
If you ball with Kobes then you should know how these stack up in term of grip performance...If the X traction is 10 then the XI traction is a 8.5.-9
