Foot posture has long been considered to contribute to the development of lower limb musculoskeletal conditions as it may alter the mechanical alignment and dynamic function of the lower limb to consider the structural status of the foot is effective in the process of training, implementation skills and preventing injuries in soccer player adolescents. Aim. The aim of the study was to understand the foot posture characteristics of Russian soccer players and determine the foot posture characteristics of 10-12 years old soccer players foot structure. The obtained data clearly indicated that there was no inappropriate position of foot in both leg. Just, calcaneus position (-0.07±1.27) was in inappropriate situation. This variable can influence on teaching and performing technique in soccer players. Knowing this result can help the teacher for improving or resolving all limitation in early ages. Reform feet should be done in children because in upper age is more than impossible to reform feet structure. Also, understanding the structural status of the foot is effective in the process of training and preventing injuries of adolescents. Methods. The overall FPI, obtained as the sum of the scores of its six individual criteria, was determined in 18 soccer players10-12 years old in static bipedal stance and relaxed position. Results. The Mean ± SD Foot Posture Index scores ranged from (-0.07 ± 1.27 to 1.67±0.48) in the left foot and (0.00 ± 1 to 1.67±0.48) in the right foot. Conclusion. The result of this study showed that foot posture of soccer players 10-12 years old are in normal situation. This can be useful for coaches and parents to prepare appropriate program to learn more effectively and faster and also safety condition for preventing injury in future. There was an appropriate structure of the both foot in soccer players adolescents. Also, there was an inappropriate structure of calcaneus of the left leg.
