After being diagnosed with a slight case of athlete's foot in between several toes, my doctor recommended that I use Tinactin to prevent future occurrences of the affliction. I use Tinactin every night after my feet are thoroughly dried. Spray it between the toes. It comes out of the can in a powdery way and dries quickly. It feels cool during application. There is no smell and it has not bothered my skin. The athlete's foot fungus has stayed away, too. However, that could be due to other things, as I am not a doctor. But I can say it hasn't returned. The product also reduces itching and burning. Very easy to use. The can also says it can be used for ringworm, another fungus. I recently traveled by car and I was able to tuck the can in my suitcase. So it is very portable. I'm not sure if you can buy a trial/travel sized can but it would be a worthwhile investment, especially if you plan to walk a lot.
