I thought these shoes were so cute and I tried them on in a store, but they didn't have my size.  At the time I thought they were comfortable so I ordered them online.  One trip around the museum I work at and they had ripped the skin off the back of my ankle to the point that I had to push the backs down and walk around like they were clogs all day.  I tried them a few other times and they always hurt the back of my ankles.  Plastic is not a good idea for shoes.
