Try rotating through 2 or 3 pairs of shoes such that you let every pair completely dry out for at least a full day before wearing them again. You might notice that they actually do take longer to physically deteriorate, and probably also longer to start smelling: the longer and more thoroughly you dry your shoes between wears, the better. To reference your rather ironic username, that's common sense (and verifiable by you if you're willing to do the experiment).
