I used to have a sweat and odor problem with my feet. I often felt uncomfortable at work and scared that someone would notice the odor. The first thing I would do when I’d get home is rinse off my feet with water & soap as they were covered in sweat and produced a bad odor. After using Blue Sand for a few days I didn’t even notice how the heavy sweating had stopped and that my feet stopped smelling. I completely forgot that I even had those problems. Finally I have found a product that is economical, easy to use and it works.
