Introduction to Forensic Shoe Sole Databases
Forensic shoe sole databases are powerful tools that aid forensic investigators in the identification and analysis of shoe prints found at crime scenes. These databases contain extensive information about various types of footwear, including sports shoes, work boots, and casual footwear. By comparing the characteristics of a shoe print with the data in the database, investigators can identify the make and model of the shoe, potentially linking it to a suspect.
One such advanced forensic shoe sole database is SoleMate FPX. Developed by Foster + Freeman, SoleMate FPX combines a comprehensive footwear evidence management tool with an extensive reference database. This cutting-edge system allows investigators to rapidly identify shoe prints and streamline the investigative process.
The Significance of Shoe Prints in Forensic Investigations
Shoe prints found at crime scenes can provide valuable insights and evidence in forensic investigations. Like fingerprints, shoe prints are unique to individuals and can help establish a link between a suspect and a crime scene. By analyzing shoe prints, investigators can determine the size, pattern, and wear characteristics of the shoe, which can be crucial in identifying suspects or excluding innocent individuals from the investigation.
Shoe prints can also provide information about the movements and actions of individuals at the crime scene. They can reveal the direction of travel, the presence of multiple individuals, and even the type of activities that took place. By carefully analyzing shoe prints, forensic investigators can reconstruct the sequence of events and gain a deeper understanding of the crime.

Other Forensic Databases and Tools
While SoleMate FPX is a leading forensic shoe sole database, there are other tools and databases available for forensic investigators. These include:
Integrated Ballistic Identification System (IBIS)
The Integrated Ballistic Identification System, maintained by the Bureau of Alcohol, Tobacco, Firearms and Explosives, is a forensic database that contains bullet and cartridge casings retrieved from crime scenes and test-fires of guns. While not specifically focused on shoe prints, IBIS can be a valuable tool in forensic investigations.
Paint Data Query (PDQ)
Maintained by the Royal Canadian Mounted Police, PDQ is a database that contains the chemical compositions of paint from various car manufacturers. While primarily focused on automotive paint, PDQ can also be used to analyze paint found on footwear.
National Automotive Paint File
The National Automotive Paint File, maintained by the Federal Bureau of Investigation, contains samples of automotive paint from manufacturers. This database can be used to compare paint chips from cars with samples in the database, aiding in the identification of vehicles involved in crimes.
Glass Evidence Reference Database
The Glass Evidence Reference Database contains samples of glass from manufacturers, distributors, and vehicle junkyards. While it does not determine the source of an unknown piece of glass, it can assess the relative frequency of two glass samples having the same elemental profile.
These databases and tools, along with SoleMate FPX, provide forensic investigators with a range of resources to aid in the analysis and identification of shoe prints and other forensic evidence.
The Role of Research and Development in Forensic Shoe Sole Databases
Research and development (R&D) play a crucial role in advancing forensic shoe sole databases and tools. Ongoing R&D efforts aim to improve the accuracy, efficiency, and effectiveness of these databases, enabling investigators to analyze shoe prints with greater precision and speed.
Organizations such as the Organization of Scientific Area Committees (OSAC) and the National Institute of Justice (NIJ) prioritize research in the field of forensic shoe sole analysis. These organizations identify research needs, set research priorities, and allocate funding to support innovative projects and studies.
