Great shoes!  These shoes are light and fast.  They are low cut and allow for easy lateral moves, but as such, they don't offer ankle support.  The arch support is obvious when you put the shoes on, and the forward lacing helps with a snug, comfortable fit.  I do think they run about 1/2 size large, but with thicker athletic socks, the fit is great.  They are pricy, but in my opinion, they are worth every cent.
