My husband has plantar fascitis.  His heels were hurting him terribly.  He is on his feet all day at work and we had tried every over the counter insole available, and, a custom made orthotic insole that actually made the pain worse.  We had tried Nike, New Balance, Propet, Dr. Scholls, and Reebok shoes and didn't get any relief with any of them.  These Spira shoes in a wide width (E) provided relief.  The problem isn't entirely healed, he still experiences pain daily.  But I have absolutely no doubt that if not for these shoes he would not be able to work right now.  He has been wearing them for about six weeks and I can't anticipate ever buying another brand of work shoe for him.  Will probably invest in a pair for everyday also.
