I don't know if Nike is making their shoes smaller, but this size 12 shoe is tighter than my other Nike size 12 basketball shoes, and they're shaped more like running/walking shoes than basketball shoes. I'm sure they will fit better when I break them in, but I ordered another new pair of Nike basketball shoes at the time time, and those other shoes fit perfectly without needing to be broken in. With these shoes there is no ankle support and there is no room for my toes. Nike is the only shoe brand I wear in a size 12 because they make them small. With every other shoe maker, I wear an 11.
