My reason for trying this was for ridding of foot sweat smell on 2 pairs of shoes. It's supposed to kill the bacteria, etc.Between the 2 pair - (one clogs, the other water shoes) - I used almost the entire bottle of Dr. Mist. Different intervals, letting it dry and air out outside. After atleast 6 hours of this, I wore both pair for less than an hour each and the smell was back full power.Forgot to mention - prior to putting them on - I also used the glide on deoderant version on my clean feet. Not impressed at all. Glad I only wasted $9 instead of $15 (flea market price). Save your money. If I do find something that works - I'll update my comments.
