Is this athlete's foot? Athletes foot?

Pics: http://imgur.com/a/T28pB I've never had anything like this before. I noticed that around the bottom of my feet I started suddenly having some dry skin and a few white blisters were forming on the bottom of my feet. I used an entire tube of Lotrimin and that did nothing. I switched to Lamisil for two tubes of that, and that didn't seem to do anything either, plus I started noticing more white blisters forming under and in between my toes. I went to the doctor and he gave me Ketoconazole 2%. All of the aforementioned I had/have applied twice per day religiously and have also tried to keep my feet dry as much as possible, using powder in my shoes, etc. Since starting the ketoconazole about a 1.5 weeks ago though, my skin has been peeling more. It doesn't hurt or itch (though it did itch prior to using the cream), it's mostly as if my skin is just kind of..peeling off. I have been on the antifungals for a little over one month now. Is this athletes foot?
