^{The Shoe Model Database is a collection of various shoe models, each with accompanying images and textual information. This database is created to assist law enforcement in solving cases and bringing peace to society.}

^{What can the Shoe ModelDatabase do? Can it help solve cases?}

^{(1) Enhancing the use of footprint evidence at crime scenes and improving footprint collection rates.
By collecting footprints at crime scenes and identifying the brand and model ofthe shoe that left them, investigators can gain valuable clues for solving cases. This process can also motivate crime scene examiners to collect footprint evidence more actively.}

^{(2) A comprehensive shoe model database can be utilized by an entire city or even nationwide police forces.
The database is extensive and designed for shared use. Law enforcement agencies in different locations, within the same city or across the country, can all access and utilize the same database simultaneously.}

^{(3) Comparing crime scene footprints with shoe models in the database does not require professional forensic expertise.
Matching a footprint with a shoe model is straight forward—one only needs to be familiar with the database. Identifying the shoe model that left the footprint does not require expertise in analyzing wear patterns on the shoe itself.}

^{(4) A professional database serves as the foundation for training forensic footprint examiners.
The field of forensic footprint analysis has transitioned from physical evidence examination to digital evidence analysis. A well-developed database will significantly enhance the efficiency and effectiveness of examiner training.}

^{Building a professional shoe model database for criminal investigations is a large-scale project.}

^{(1) To ensure the data remains up-to-date and comprehensive, continuous collection of new shoe models from mainstream and popular brands worldwide is essential for effective application.}

^{(2) A team of professional technical personnel is required to maintain the software system and database, as well as to release new data packages regularly.}
