Footwear Make/Model Determination


The latest edition of SoleMate, Foster + Freeman's footwear database, contains details of approximately 30,000 sports, work and casual footwear. Its purpose is to identify footwear from prints recovered from scenes of crime and it may be used as a stand alone system or with SICAR, the company's footwear evidence management system.

Each record in SoleMate contains the footwear's manufacturer, the manufacturer's reference for that item, the date of its release on to the market, an image or off-set print of the sole, several pictorial images of the footwear's uppers to aid recognition, and a set of pattern feature codes that facilitate search and match operations. Where different manufacturers have used the same sole unit (a common practice), all relevant SoleMate records are linked, to allow the operator to consider all of the footwear that might have been responsible for the crime scene print.

To use the database, the scene of crime footwear print is first assigned a set of pattern feature codes, a simple procedure that requires the operator to identify a number of elemental pattern features, such as circles, diamonds, zigzags, curves, blocks etc. As there are a variety within each type, a number of options are presented, as images, for the operator to select the best match. The codes assigned to these pattern features form the basis of the database search. The results of a search are then presented in descending order of pattern correlation for the operator to examine visually.

SoleMate is continually updated and distributed to subscribers every three months on DVD.

Webster Groves High School Shoe Outsole Database


Jeanette Hencken with the help of her students in the Advanced Forensic Science Research class at Webster Groves High School (WGHS) in Missouri collect data and photograph footwear at local Payless ShoeSource and Walmart stores. This information is edited and maintained by students and staff at WGHS as a resource of the law enforcement community.


Normally, the data is collected twice a year in March and October. Each time, photographs are taken and information is collected on approximately 150 shoes at retailer. For each shoe, the following information is recorded: manufacturer, model name, model number, and date of collection. Jeanette has requested that interested parties contact her to learn more information about these shoes. Jeanette also welcomes search requests if you have an unknown crime scene impression that you'd like her students to search. She and her students do not claim to be forensic footwear experts, but they enjoy the opportunity to offer their search services to the flaw enforcement community.
