atheletes feet ?
If you are getting atheletes feet reacuring all the time regardless of what you do it might be a reinfestation check what you walk on. I put powder all over the carpet in my hostel room at least that you can walk on and then a bit in my shoes as perscribed , [i've even once caught a someone complaining about his own cearing up from it as he had deliberatly kept it untreated].
walk it into the carpet and leave it there when its walked in fully and can't be seen then it's at it's best effect dont hover immeadiatly and walk it in.
