Update: Ok, I've worn these all day, walking all over the place and can say that (a) I adapted quickly to the strap closure so it's fine, and (b) they are true to Crocs generally - very comfortable. Nothing rubs or chafes or doesn't bend or bends uncomfortably, etc.  Great shoe. GREAT!

I've only tried them on and walked around my apartment, where they felt very comfortable and looked quite nice. For me the ultimate test is: can I walk around in them all day, from the train to the office and back, etc.  I haven't done that test yet. But the initial try-on went well.

I *think* the way the ankle strap closure was designed it was meant to be easier than dealing directly with the buckle but for me it isn't; perhaps it's a bit quicker I guess. In any case, the only thing I wish is that there was a tiny bit of stretchy material in the ankle strap (as with a pair of Sanitas sandals I love) because it makes it just a tiny bit more flexy for walking. But not a big deal.
