Foot fungus, sometimes called “athlete’s foot”, is an infection caused by fungi or parasitic yeasts located mainly on the skin around the toes. As these crops develop in a humid environment, it is essential to always have dry feet. To do this, you should wear 100% cotton socks, always dry your feet well after showering and try to leave them in the open air as often as possible. But despite all these precautions, it can be difficult to get rid of a yeast infection.
