Abstract
The lightweight footwear of the present invention maintains excellent durability and improves heat resistance, so that contraction percentage due to a change with the passage of time is significantly low, rarely causing deformation, and thus, the lightweight footwear may be used in a high temperature and sanitary environment. In addition, the present invention solves the problem of the occurrence of premature foaming due to injection molding and a pattern on the appearance due to dispersion failure, thereby facilitating injection molding.
