These sneakers are the 3rd pair I've had of the same made and model.  Best running shoe ever.  But this time, the sneakers that were sent to me were marked with the right size tag....but put on a much smaller shoe.  I am a serious distance runner and these shoes severely blistered my feet and it was so painful.  I thought I was going crazy that these weren't breaking in.  Please make sure that your product goes through a quality control process because was a terrible mistake.  I am extremely disappointed.
