I saw the rainbow ones at the Adidas employee store yesterday. Ended up getting the black and red road shoes for 50% off. Such a good fitting shoe...damn.
...I've read that some guys that intend to strictly use the 2's for playing ball in have gone down a 1/2 size for a snugger fit. Probably depends on your personal preferences though. For the most part they are true to size and have more room in the toe box area than the narrow 1's did.
I got a pair of the grey/white/black Lillard 2's a couple days ago and played hoops in them last night. Very very comfortable! I also got a pair of the new 2016 Nike Zoom Hyperrev. Gonna play in those tonight. Based on walking around the house, the Lillard's are much more comfortable.
