Why is it that our feet get smelly but our hands don't?

Wearing socks/shoes makes for a warm, moist environment that's perfect for bacteria and fungus to grow. Your hands are constantly exposed to the air, so no bacteria, no stink.

Bromodosis, or smelly feet, is a very common medical condition. It's due to a buildup of sweat, which results bacteria growth on the skin. These bacteria cause bad odors. Fungal infections like athlete's foot can also lead to bromodosis.

We don't go around with our hands in smelly shoes.

People don't tend to wear shoes and socks on their hands, and if their hygiene standards are what they should be, their hands are washed several times every day, not just once.

Because you don't put shoes and socks on your hands.
