I gave the shoes 1 star rating, because I am not convinced they are the product for me.  I received product ~1 week ago, wore them 3 times and still not impressed.  I do not feel any joint relief (knee), instead it provokes the pain.  They tend to run half-size too small.  I am very tempted to return them, but afraid they will do the trick if I try them one more time.  I wiil try them for one more wear, and if they do not "propel me forward" and alleviate my knee pain, it is back to Asics, and Spira a distant memory.
