Feet smell because small microbes thrive in dark, damp places and sweaty feet seem like heaven to them.
When these bacteria reproduce, they create gas, in much the same way intestinal bacteria reproduce and form flatulence.
The two main microbes that like to party on feet are Corybacteria JK and Brevibacteria-linen, both of which smell pretty bad.
Why are some people more prone to smelly feet than others?
They may have more active sweat glands in their feet or more creases that moisture can stay in. Others don’t expose their feet to the air often enough.
If you have a problem with foot odor, try carefully washing and drying your feet more often and leaving them out of socks and shoes to air-dry.
Some experts suggest using an antibacterial substance like Betadine or Neosporin for a few days and seeing if that doesn’t solve the problem.
Keep your shoes clean and dry so bacteria won’t grow.
If these things don’t help, there are prescription medicines available.
