Causes of athlete's foot
The same fungus that causes ringworm and jock itch can also cause athlete’s foot. You can get athlete’s foot when you often wear damp shoes and socks. This warm, humid environment encourages this fungus to grow. Most often athlete’s foot is spread when you come in contact with someone (or something) that’s been contaminated by the athlete’s foot fungus. You can get athlete’s foot from other people, floors, shoes, or even towels. Men are more likely to get athlete’s foot. But anyone can get it from walking in infected areas (like public locker rooms, saunas, swimming pools) or from sharing shoes or linens with someone who has the infection. Your risk increases when you wear damp socks or shoes that are tightfitting.
