Introduction
Along with the change of manufacturing technology, market demand and lifestyle as well as
the improvement of life quality, casual shoes have been popular in daily activities. However,
in the current footwear standards, there is no standard for casual shoes. Therefore, standard
for casual shoes is in urgent need to provide consumers with more suitable shoes in daily life.
Additionally, some of the materials and various chemicals are added in shoemaking process.
Some of these materials are limit substances. Therefore, foot health should not only be
emphasized on the shoes' physical performance, but also on the effects of the materials
exerting on foot and even body health. Therefore, this standard raises technical requirements
on the aspect of limited substances of casual shoes. This also reflects the integration of our
nation’s shoemaking with international shoemaking.
