Obesity is a state where there is an abundant storage of adipose tissue that has a denying effect over the health, according to world health organization (WHO) in the year 2014, 600 million were obese in that 1.9 billion were young adults [1,2]. Increased body fat that has been accumulated to an extent that it may have a negative effect on health, leading to reduced life expectancy and/or increased health problems [3] . Every 1 out of 5 adults are suffering from foot pain [4] . Foot pain is

... rted commonly in overweight and obese individuals [5] and increased BMI [6]. Flat foot is a biomechanical disorder in which the arches of the foot becomes flattened, and alters the transmission of forces from superior extremities to the ankle and the foot [7] . Excessive fat deposition leads to increased loading of pressure over the arches causing flat foot [8, 9] .Obesity, illness, faulty biomechanics and prolonged stress to the feet can develop flat foot [10]. In obese individuals there are changes in foot due to excessive mechanical loading during walking [11] . Footprint parameters act as an essential tool in assessing the differences in foot morphology and foot types [12] [13] [14] [15] [16] [17] [18] [19] [20] . Individual wide variations of foot arch can be revealed using foot print parameters [13] . These foot print parameters are systematically used to assess the configuration of the arch [12, 13, [17] [18] [19] . Arch height is a simple and effective parameter in assessing the medial longitudinal arch height [21] . Footprint angle (FA) and Chippaux-smirak index (CSI) are the most effective parameters to assess the characteristics of foot morphology [22, 23, 25, 26] . Studies have shown the prevalence of flat foot in general population but the distribution of the flat foot problems are high in overweight and obese individual, this lacunae of knowledge in literature about the obese individuals foot problems can be achieved by this study. Hence the aim our study is to evaluate the prevalence of flat foot in normal, overweight and obese individuals and to establish the relationship between BMI and morphology of the foot using foot print parameter.
