Footprints are the impressions left behind on a surface by a person either walking or running. Usually, a footprint is seen as an indentation in a surface, although it could be something placed upon the surface that was on the bottom of the foot e.g. painting your feet and using them to print footprints onto paper. A series of footprints made by a person is called a trackway, although tracks are more often associated with tracking wild animals.
Footprints can be very useful, for example, in forensic science a footprint from a crime scene can help to identify a criminal. It could also show escape routes and perhaps lead them to where the criminal has fled to, making them easier to catch because they know the vicinity the criminal is in. They can also show more in detail facts about the criminals identity e.g. body mass, height or gender.
