Effective solution
This product is an effective treatment for problem shoes, old and new.  Ideally, you would apply it each time you remove your shoes for the day, from the time you bought the shoes -- and that works great.  In addition, this did a nice job on older shoes that already had an odor problem and had been smelling up the closet.  Those shoes required some follow-up treatments, but the product was the best solution we have found after many unsuccessful attempts.
