Shoeprint information is gathered from crime scenes by photography, a cast or electrostatic lifting. This impression is then used to arrive at three main types of classification. Firstly there is the basic match in shoe size, secondly matching a shoe print to a particular brand or model. This can be achieved by keeping a database of product information from shoe manufactures (this data is abund...
