I have five pairs of Bloch flats and they all fit a little differently.  These ones are a little stiffer than the others and run slightly tighter (my foot is a little wide, so I notice it more).  This is very minor, however, and with a little bit of wearing, they should fit perfectly.  They do have a more oval than round toe, but I really like the shape - very feminine.

To compare, I just held this shoe up next to the Bloch Pearl flat (which is similar to all of their other plain, tie, non-patent flats) and the soles are almost identical with only a few millimeters difference on the toe (making it slightly more oval).  What seems to be making the biggest difference in the shape is that the Alia flat is made of much firmer leather than the other flats.  While this makes them relatively stiff when compared to other Bloch flats, they are not too stiff in general.

The Briney Rose color is beautiful, soft, feminine, and classic.  I'm very happy with these shoes.
