Dirty truth about what’s in your socks: bacteria, fungi, whatever lives between your toes

Business To Business, London, 03 August 2025: Your feet are microbial hotspots. The space between your toes is rich in sweat glands, and when covered by socks and shoes, this creates a warm, moist environment—perfect for microbial growth.
 
In fact, your feet may resemble a tiny rainforest of bacteria and fungi, harboring anywhere from 100 to 10 million microbial cells per square centimeter of skin. They host a remarkable diversity of microorganisms—up to 1,000 different species per person—and feature a wider variety of fungal species than any other body part.
 
This means that your feet aren’t just sweaty or smelly; they are genuinely biodiverse ecosystems teeming with microbial life.
