This article summarizes systematic reviews of the literature related to foot deformities. The aim of this review is to analyze the feet of preschool children and to identify the factors that lead to the accommodation of this deformity. All data sources have been selected from relevant sources from websites, journals and original scientific articles. In this paper, seventeen papers addressing the problem have been analyzed. Systematic review of the papers presented here is consistent with the PRISMA consensus. What has so far revealed is a strong correlation between body weight gained by gender with the onset of flat foot deformity. All the studies conducted allowed for a positive association between body weight and the frequency of flat foot occurrence. The results of the study examining the association were found with the occurrence of deformation and concluded that the flat foot in the highest frequency occurred in children aged 3 to 5 years, and after that age the frequency often suddenly decreased. A gender difference was also observed. Specifically, in observing the girls and boys of the same age, there is a higher incidence of flat feet in boys. The childhood period is a period of rapid growth, and accordingly, it takes time for the skeleton, musculature and ligaments to adapt to increasing daily challenges. What still remains underexplored and needs more attention is to assess the period during which the foot structures connections are finally established in order to decide which period of flat foot emergence represents the ultimate pathological condition to be treated seriously.
