The straps material are too hard.  They scratch my feet when I walk.  I only wore it one time.  It hurt my skin so bad and it took me 3 weeks to heal.  The marks are still there (see photos).  I wish I can return it.  But since I have worn it, I am afraid that my return will not be accepted.  I don't know what I am going to do with it because the shoe really looks good.  So sad!
