What is the best cream for fungus/athletes foot?

It all depends, not all anti-fungal creams work the same for everybody. I personally think lamisil sucks, tinactin seems to work okay most of the time. Most of the anti-fungal creams have clotrimazole(1%) in them all of these creams are OTC(you can buy them in the store) anything with more than 1% clotrimazole has to be prescribed. The best anti-fungal I have used and have had other with the same results comes in an aerosol can it is Desenex Antifungal Spray Powder and it doesn't have clotrimazole in it, but it works really well. It is a bit pricey though so it is entirely up to you whether or not you want to try it out. Hope this helps.
