When I was twelve I ended up getting athlete's foot from sharing my roller-blades with all my friends. My mom bought me all kinds of foot powders and treatments. None of them ever worked over the 1 year period I had to deal with the horrible itch. One night, an act of pure desperation led me to grab some white toothpaste and slather it on. The hunch came from its effectiveness on acne. Went to bed with a cold tingle on my feet. Woke up the next morning and was so elated to see that my feet looked 100 percent better and most importantly the itch was nonexistent.
