Brown spots on the bottom of your feet may be benign or serious.
Most brown spots on the bottom of the feet turn out to be nothing — a bruise you do not remember, friction from a shoe, or pigment that simply runs in your family. That is worth saying first, because it is true, and it is why most people leave them alone.
It is also why the ones that matter get found late. A spot on the bottom of your foot is somewhere you almost never look.
