Identicator LE-25 Inkless Foot-Shoe Print Kit Once a footwear impression is recovered from the scene of a crime, it should be compared against examples of known footwear impressions. The Inkless Foot/Shoe Print Kit helps you take exemplars from suspect footwear, but leaves no visible residue on the footwear or foot and develops sharp, black impressions of the footwear or friction ridges. Each Inkless Foot/Shoe Print Kit comes with a chemical coater and 100 chemically-sensitized sheets. To make a footwear impression, press the shoe or foot on the coater, making certain the sole is completely covered with the colorless chemical. Then, step on the sensitized sheet. Each sheet is large enough for the average shoe (6½" x 12"). Impressions appear immediately, looking as if they were done with black ink. This clean and easy method is a boon at crime scenes where possible suspects are present. The exemplars of the suspect’s footwear can be taken immediately without the use of ink, powders or other materials which will soil or stain the shoes.
