Background: Problems arise if the position of the sole bones shifts or loses alignment because this will affect the structure of the body. A decrease in the curvature of the soles of the feet causes a person to experience a problem known as flat feet. If this happens, an individual will not only have difficulty walking, but will also experience balance problems. However, the type of foot arch does not determine a persons ability to move because individuals who have high or low foot arches can still move without problems. Method: The research design used in this research was the literature review method. This technique is carried out with the aim of revealing various theories that are relevant to the problems being faced or researched as reference material in discussing research results. Results: Balance plays an important role in starting to completing functional activities in daily life. Physiologically, sports injuries occur due to an imbalance between workload and the ability of the bodys tissues to carry out sports activities. One cause of lack of balance is flat feet. Flat feet cause balance problems, instability, continued deformity, complaints of fatigue when walking for a long time, shoes on the heels wear out quickly, excessive surface injury, and pain. Conclusion: Based on the results of this study, it is concluded that there is a relationship between flat feet and static balance in 12 year old children, and there is a difference in the influence of flat feet and normal feet on dynamic balance.
