I come from a family of smelly feet - apparently it's a genetic thing.  Anyway, it's always been a struggle to keep the shoes from smelling really foul after a few weeks of wearing them. We've tried powders, other sprays (including body deodorants), washing them with household cleaners designed to elimiate odors, and on and on.  Nothing really works.  Until now.  I like this stuff.  A little squirt at the end of the day, leave the shoes to dry for a few minutes, then store them away, and next time you take out the shoes to wear them - no stink!  We can finally take off our shoes in the family room to watch a movie and not have to leave the room because of the smell.  Oh, yeah - I'm definitely getting more of this spray.
