I am mid to lighter weight woman with flat feet.  Love these running shoes.  Great deal, great price.  I inadvertently ordered 3 pair...will definately use them.  Run and cross train 6 days a week.  Mizunos don't often go on sale so getting these for the price I did was awesome.  I run in saucony as well.  Do not like any Nike or Asics running shoes.  Just have not had good experience with those brands on my feet.
