Purpose of work - to analyse influence of the program of prophylaxis of violation of vaults of foot on its biomechanics descriptions. 40 children which studied in a tourist class took part in an experiment. Linear and angular biomechanics descriptions of foot of children are certain. A dynamics and increase of the probed indexes is analysed during realization of the program of prophylaxis of violation of vaults of foot. Information which testify to the improvement supporting spring properties of foot of children is resulted. The program of prophylaxis of violation of vaults of foot is recommended
