Hi E S:
I watch the doctors show each day, and they had a woman on asking what to do about her stinky feet. They claimed it was bacterial,and the combination of your sweat and bacteria and the material in the soles of your shoes is what causes the terrible stink. They happened to have a podiatrist there ,and told her to boil some (black tea bags) wait till its warm,and soak your feet in the black tea for 30 minutes. They said after doing this a few times,it will rid you of the bacteria that is creating the odor. Dah Dah..... Best of luck to your girls. (happy feet) : )
