So we were having issues in our house with stinky shoes - I guess the kiddos got mommy's stinky feet :0  So I went looking around and I found this great product by Trinova.  It is called "Shoe Renewal Spray" made with peppermint, tea tree, and thyme essential oils.  It is all natural - so no chemicals - which we get enough in the rest of our life.  It smells very good - I have found that if you have ground in smell - stankface - in the shoe - that it just sort of hides the smell.  If that is the case in your house wash them and then put them outside in direct sunlight then spray.

I do love to spray this on my son's feet first thing in the morning and let them air dry before I get his socks on - and my family loves that I put it on and save them from the "stankface" look to :)
