OK Ive been playing ball in these about a week now and a few things Ive noticed.
As people have said already they take time to break in so the fit dosent feel revolutionary out the box and you can expect blisters and cuts the first couple of wears regardless of sizing /socks etc. (Not a good start I know)
Once the toebox takes shape the shoe becomes more responsive, the let down for me is the traction. There is good "feel" with the low to the ground stance however the pattern on the sole is bulky (similar to the chain pattern on the 9s) making the shoe feel less connected on dusty courts.
Cushioning is decent, the shoe felt good when running and making cuts but landings can be a bit harsh if your a forefoot plant type. I felt the toebox got a bit cramped when you tighten up the laces, the material between the foam in the toebox is quite harsh on the feet and can cause blistering but the softer posite material at the end ensures no bruised toenails so its not all bad.
Support is good with a decent lace lockdown, there is a good balance between ankle movement and support and if you need the tight fit the tongue has decent padding. The shoe is much lighter than the X but somehow its not light enough to make it feel revolutionary, I guess its well balanced in terms of weight - its a durable shoe yet light enough to suit guards / small forwards (faster players).
One thing I found lacking with this shoe is arch support, the lunar/zoom insole is very flat and if your a player who requires arthritics or additional arch support sizing could be a problem. If you remove the insole there just isn't enough there to make the shoe comfortable - I found this was a similar problem on the jordan 2011.
Overall Id rate these around 7/10, price is a big issue for me on these I just don't see the "enhancements" warrant the price tag. Also when compared to shoes like the Jordan 28 SE and the melo M9 it dosent preform any better in fact out the box the jordan 28 had far more immediate feel and comfort.
I rate the X the same but that shoe looses marks for for different reasons, the Xi will never be my go to shoe, Im not over impressed with ascetics of the shoe the KP colorway is the main selling point on this for for me and if i was to see these in a different colorway on sale I dont think id cop "just for ball" as there are better shoes for less money.
