I just came back from my second session with the 306 Cup. They are hands down my new favorite skate shoe! I've been through many NB models and these feel like a best-of, of sorts, combining features of some of my favorites. Notably the wider toebox of the 272 (not quite as wide though), the heel cup/lock/feel of the 933 and the general feel of the 440 V2 (but with a better/denser insole). Plus the "satin" tongue straps are by far the best of any NB I've tried (I usually cut them out because they're uncomfortable with my left gout foot). And how the front part of the sole is quite flexible, but the back/heel area still feel super supportive. The fit is great and I've had zero heel slip. All in all, a total winner. Thanks a lot NB folks <3
