Ordered shoe 1/2 size larger than normal street size (I wear a 6M).  In this style, the 6.5M size too large.  I also ordered the Lilina style and in a 6.5 it was perfect.  Although the forefoot sole is covered in suede, the heel was leather and a bit slick.  The strap was a bit of a challenge to open and close.  Minimal support in the shoe bed and the heel did not feel very stable.  I kept the Lilina style and returned this one.  I wrote a review of the Lilina too if you care to read it.
