My two cents on sizing:
I bought three pairs from the initial offering, all size 12 (Grasshopper, Cats, and Reed Mid). The Grasshopper and Cats fit true to size, and the Reed Mid is a little shorter, but still fits me comfortably. I noticed this when I tried to put the cork insoles from my Reed Mids into my Cats, and that insole slid around inside that shoe. It did the same thing in the Grasshoppers.
I'm somewhere between an 11.5 and 12, and the shorter shoe makes for a more functional skate shoe (less space at the front of the toe box), and the longer ones make for more comfortable non-skate shoes. In this particular case it works out perfectly for me because of the three I bought, the Reed Mids would be my first choice of the three to skate in, the Cats are my first choice for a nicer, change-of-pace shoe, and the Grasshoppers are my first choice for an all-around do everything workhorse.
