Qiu Li, a senior engineer at the China Leather and Footwear Research Institute, wrote in “A Pair of Good Sandals” that it is easy to distinguish a pair of children’s sandals, which can be divided into five simple steps (the following standards apply to all children’s sandals).
Bend the soles and the sandals that can be bent at one-third (forefoot position) are qualified. This design conforms to the walking law, making the soles of the feet more flexible and more comfortable to walk.
During the purchase of sandals these few days, I found that many merchants have emphasized that there is a bendable groove in one-third of the places, which shows that this standard has become an industry consensus.
Pinch the heel of the sandal and the front Baotou with both hands. If there is no hardness, it will not give enough protection to your child’s soft ankle, toe, and heel, which is unqualified.
Twist the sandals with both hands. If the shoes are too deformed, they cannot be restored, indicating that the shoes are unqualified.
Normal sandals must have sufficient stability to regulate the correct walking style of children. If it is too easy to deform, children can easily sprain their feet during walking or develop bad walking habits.
The handle is extended to the forefoot of the inside of the sandal. Press one button. If it is too soft, the shoe is unqualified. The inner cushion of the shoe should not be a very soft sponge, and the rebound elasticity should stimulate the development of the plantar nerve of the child.
Smell the sandals for any odor, if any, the description is unqualified.
