Introduction: In cases of mass explosion and disasters it becomes difficult for forensic experts to identify the individuals as most of the times body gets mutilated. As various parts of human body grow in proportion to each other, relationship amongst them can be established. Due to variation in size of feet, foot size can also be used to differentiate between males and females. Materials and Methods: A Cross-sectional observational study was conducted on 200 individuals (100 males and 100 females) above 18 years of age in the Department of Forensic Medicine and Toxicology, Hind Institute of Medical Sciences Ataria Sitapur, U.P. The foot length and breadth were calculated with the help of a sliding vernier calliper. The foot index for both genders is derived by dividing the foot breadth by foot length and multiplying it by hundred. The data was collected, analyzed and subjected to statistical analysis. Observations & Results: The mean value of right foot index in males and females was 38.32and 37.44 respectively. The mean value of left foot index in males and females was 38.01± 2.21771 and 37.05 respectively. Foot Index showed a statistically significant difference between males and females as p value was found to be below 0.05. Conclusion: Males have a longer and wider foot as compared to females. Significant difference in the size of foot amongst both sexes makes it as an important part of human identification.
