FOOT AND TIRE PRINT CASTING KIT
Footwear impressions and tire prints are among the most valuable forms of physical evidence found at crime scenes. They can help investigators determine the direction of travel, identify suspect vehicles, and even link a specific shoe or tire to a criminal. A Foot and Tire Print Casting Kit plays an essential role in preserving these impressions accurately, allowing forensic experts to analyze them long after the crime scene has been cleared.
This specialized kit includes all the tools necessary to recover three-dimensional impressions left in soil, mud, sand, snow, or other soft surfaces. When used properly, it captures every ridge, groove, and unique wear pattern in remarkable detail.

The Casting Process (Step-by-Step)
Secure and Photograph the Impression
Before touching anything, investigators document the print from all angles.
Prepare the Casting Material
Dental stone or plaster is mixed with water according to a controlled manufacturing process that ensures ideal consistency and durability.

The casting material is poured carefully into the impression to avoid air pockets or disturbances.
