The aging of the world population is a phenomenon of expression in an increasing number of countries, especially in developed countries. This process is characterized by a constant increase in life expectancy and a drop in fertility. These factors together result in a large number of elderly people and a significant reduction in children and young people. For every five people, one is over 60 years old, which represents a quarter of the world's projected population by the year 2050 (WHO, 2015). The study consists in studying the changes in the feet of the elderly during human aging.
