First, security
Why do you mention safety in the first place? Now everyone is talking about the issue of environmental protection. In the production of shoes, there will be some harmful substances in the shoes, such as hexavalent chromium and benzene. Hexavalent chromium will cause damage to liver and kidney functions. Damage can also cause retinal hemorrhage, optic atrophy, etc. in the eye. This is a problem that our parents must not ignore. That is to say, when we have the conditions to choose shoes for our children, we must pay attention to its environmental protection performance, which is his safety.
Second, functionality
Functionally there are several requirements. The first is to leave a certain space for the toe cap, and a hard bag must be installed in front of the shoe to protect the footsteps. Second, the bottom of the shoe should be added with a hook to support the arch of the foot. The best way to distinguish it is that many people buy shoes that are bent at both ends and feel that the middle is soft. In fact, these shoes are shoes without hooks. , A shoe with a real hook is almost on the sole of the foot, which is the part that naturally bends when walking. Because there is a hook, it can hold the arch of the foot and will not be soft in the arch of the foot. Third, the main heel should be installed with the main heel. The main heel is the hard part of the heel. The ankle bone is relatively hard. It is best to add some sponge mouth to the extension of the heel, because the child's ankle joint is unstable and it is easier to sag the foot. , One is to support the ankle joint, and the other is that the calcaneus can grow vertically without twisting back and forth.
Third, fit
The shoes must be suitable for the feet, that is to say, the length of the child's feet should be measured, the space in the front should be reasonable, and the child should not wear shoes that are too fat or too thin, and the shoes must cover his feet well. , the shoes should be slightly larger, about 10 mm is appropriate.
