Do we say "the bottom of the foot" and "the top of the foot" in general everyday conversations as shown in the picture?
For example, "the bottom of your foot is so dirty". If we say "your foot is dirty", then it is not too accurate because only its bottom is dirty not the top one.
For "hands", we say "palm" and "the back of the hand". I don't know how to say the similar thing with "feet".
