U sm very sorry that i have had to give this sandals  a bad review.  I was  very disappointed . I really  wanted this sandals but they very uncomfortable.  I read that i had to  wear them for a  few hours  for the first week . I tried  them for two week but first  my legs  and feet were  tired  and sore.  Then my lower back hurt so much. I can't  not wear them anymore.  I am very unsatisfied.  :(
