In this manner, evidence inadvertently adhering to the footwear of the investigator is removed and preserved for further analysis. In accordance with the method of this invention, a device for recovering evidence from the footwear of an investigator is provided, comprising an adhesive evidence recovery sheet and a protective cover. Adhesive strips on an obverse surface of the evidence recovery sheet prevent inadvertent dislodgement of the sheet from the floor surface on which it is placed.
