I had to share my positive experience dealing with athlete's foot.
I had chronic athlete's foot for about 17 years. It would go away with the cream or medication and it might be fine for a month or two and then return. No matter what I did, getting new socks, shoes, etc, it would always return. The podiatrist would recommend prescription powder for my feet, all sorts of things. It was definitely athletes foot (for those who may doubt when they read the rest of my story).
In the end I just happened to change the soap I was using (for other reasons) to oil of olay (the age reducing one, but I don't think it matters). This is one of those moisturizig soaps rather than just the regular soap. My athlete's foot went away and has been gone for more than two years now. Nobody is more surprised than me. I've attributed it to the soap because nothing else changed. I haven't been using the powder or anything.
I'm wondering (and guessing) that perhaps my feet were very dry and this was creating tiny cracks in my skin that let the fungus get a foothold (unfortunate pun). Maybe my feet aren't sweating as much because they're moisturized. I really have no idea. But it's been such a noticable difference I just had to share my story.
If you're suffering from chronic athlete's foot that keeps coming back. Even though a moisturizing soap seems like the opposite of what you should do (since everything is about how you should dry your feet and keep them dry). Just try changing your soap to one with moisturizer. Maybe it's just me, but it can't hurt.
