I guess I expected better quality from Ollio.  While the design of these flats are are attractive, the fit is terrible!  I wear a size 10, but, between my toes feeling like they were going to push out the front of the shoe, and the pinching heel at the back, they are extremely uncomfortable.  While I thought of sending them back and getting a size larger, my experience with doing that is that my foot tends to ride up out of the heel because they are too big!  I will donate these to a charity and not buy any more.
