The son 11 has told or said, that the doctor on prophylactic medical examination at school has told or said to him, that if he will wear all time krossovki with arch supports at it or him the platypodia will develop, the footwear with a flat insole is necessary. I always considered or counted on the contrary and tried to buy footwear with an arch support. Probably son not so has understood the doctor, now I sit I guess. How much harmfully, that he almost always wears krossovki, to dress other footwear does not want. In advance thanks for the answer. Olga

You are certainly right - small arch supports unload legs or foots.
