I read reviews that said the heel strap was too loose, so I went down half a size.  The length actually worked half a size smaller.  Unfortunately it did not help with the heel strap.  It closed with Velcro, and if you tried to tighten it, it would pop open when you walked.  You had to leave it loose, which would make the sandals flap against your heel noisily like cheap thong sandals (aka flip-flops).  Also, the front of the sandal was boxy and not at all attractive.  The inside of the front part of the shoe was loose and uncomfortable; I could just see blisters in my future wearing this shoe.  It's a shame, since the 'Ginger' color was a perfect neutral.  Back it goes.  I can find some inexpensive thong sandals that will work better than this style.
