Nine out of 10 women are wearing shoes that are too small. The consequences aren't pretty – calluses, blisters, bunions, corns, and other problems. The constant rubbing can irritate the joints in the foot and lead to arthritis. Research suggests many kids are also wearing the wrong shoe size, which puts them at risk for foot deformities as they grow.
According to the UK's National Health Service, "Athlete’s foot is very contagious and can be spread through direct and indirect contact." The disease may spread to others directly when they touch the infection. People can contract the disease indirectly by coming into contact with contaminated items (clothes, towels, etc.) or surfaces (such as bathroom, shower, or locker room floors). The fungi that cause athlete's foot can easily spread to one's environment. Fungi rub off of fingers and bare feet, but also travel on the dead skin cells that continually fall off the body. Athlete's foot fungi and infested skin particles and flakes may spread to socks, shoes, clothes, to other people, pets (via petting), bed sheets, bathtubs, showers, sinks, counters, towels, rugs, floors, and carpets.
