I've balled some in these and I liked them. They have added a nice plastic heel counter, and with the outrigger, stability was actually very impressive. I like the freedom of movement they provide. They may not have the carbon shank, but there is no mid foot flex. There are plenty of shoes that don't have a carbon shank and perform as well or better than shoes with carbon, at least for lighter guards. ie-BB's or the old Ultraflights. Traction on the Hypers is awesome.
I've just got some Kobe V's which of course are off the charts in performance, but for a low budget alternative, the Hyper lows work well, and actually have much better traction than the Kobe V's. Never played in the IV's, which I hear had better traction. I've seen the Hyper lows at Gabriell's for $44.
