Yes, you can use toeprints for identification, much like fingerprints. Toes, like fingers, possess unique friction ridges forming distinctive patterns. These patterns develop uniquely in each person and are not genetically determined, making them a potential tool for forensic identification.
The Uniqueness of Toeprints
Several sources confirm the uniqueness of toeprints. The whorls and ridges on toes develop individually, resulting in patterns distinct from fingerprints and even from person to person. This characteristic makes toeprints a viable method for identification in specific circumstances.
- Forensic Applications: A historical example highlights the use of toeprints in criminal investigations. A safe-cracker was identified in Scotland in 1952 through toeprints left in flour. This demonstrates the practical application of toe print analysis, though it's not as widely used as fingerprinting.
- Similar Ridge Formation: Toeprints and fingerprints share a similar formation process, involving friction ridges. These ridges are also found on palms and soles.
- Not a Standard Practice: While the potential exists, toeprints aren't routinely collected like fingerprints. This might be because collecting clear, usable toeprints can be more challenging than collecting fingerprints. A Reddit thread discusses this, noting the challenges in obtaining useful toe prints, especially on living suspects.

Limitations and Considerations
While toeprints offer unique patterns, several factors limit their widespread use compared to fingerprints:
- Data Collection Challenges: Obtaining high-quality toeprints, especially from living individuals, is difficult.
- Lack of Databases: Unlike fingerprints, comprehensive databases of toeprints are not widely available, limiting their practical application in many forensic investigations.
