The Heel-Ball Index of the human foot is a quantitative measure and is defined as the ratio of the maximum breadth of heel multiplied by 100 and divided by the breadth at ball region (Breadth at heel x 100/Breadth at ball). This index was developed by a group of scientists while working on a north Indian population. Kewal Krishan, Tanuj Kanchan, Neelam Passi and John A. DiMaggio devised this index in 2012 on a sample of 303 North Indians. It has been shown that the index shows sexual dimorphism and was found to more in females than males. This index can be used as a tool for sex determination in forensic and medico-legal examinations of the human remains as well as a new trait in studying the population variability in biological anthropology.
