This is a great shoe.  I wasn't sure from prior reviews what size I should get and so I ordered an 8 (dress size 7.5, runners 8).  Unfortunately, "go up a half size" meant another half from the typical dress to runner upsize (i.e. a full size).  I did not like the mesh on the outside, concerned it would get ripped, so I reordered an 8.5 in the Kinvara3 model.  Nonetheless, it was cute, comfortable, and I'm excited to get my shoes tomorrow.
