(3) try on shoes. When trying on shoes, I think many parents do this, that is, let their children put on shoes, walk around and let his feet circulate, so that his feet may swell a little, so it is more appropriate to try on shoes. Nowadays, many people say that they should buy shoes at night. After a day's exercise, their feet were swollen before buying shoes. In fact, it is not necessary for children to be too young. The child's feet are very small and the amount of expansion and contraction is very small. There is no obvious difference, as long as the child is as suitable as possible and walks properly. There is also what we just said, children must keep standing and walking when trying on shoes. Don't let him sit down. Sitting down with little toes usually doesn't suit him. After the child puts on the shoes, he must pay attention to the length and width, and see if his toes will press the child's toes with his hands. Look at the width of the shoes. If the feet squeeze out of the sides of the upper, it means that the shoes are thin. Now many parents say that inserting a finger size is also suitable for people. Generally, it should be 10 mm, because we calculated an average value for the child's growth in one year. China children's feet grow by an average of 8.8 mm per year, which means that their arches will bend and lengthen during walking. In fact, 10 mm is enough. If the child wears shoes that are too big, check the width of the shoes. If you find that there are "bruises" on both sides of the upper of the shoe that exceed the chassis of the shoe, it means that the shoe is too narrow and needs to be replaced with a fatter model. Make sure the heel of the shoe fits the child's heel, and the foot can't shake left and right in the shoe. If the size of the two feet is not generally large, the bigger one should prevail when trying on shoes.
