PROBLEM TO BE SOLVED: To provide injection molded boots having antislip properties even on an always greasy floor surface at a marine product processing factory, a foodstuff mill and the like. SOLUTION: The boot sole 1 is made up of 100-120 pts.wt. gross plasticizer content to 100 pts.wt. polyvinyl chloride and made to be grease-resistant by blending 40-70 pts.wt. polyester plasticizer out of the 100-120 pts.wt. of the gross plasticizer content. In this case, the boot sole is smooth by eliminating irregularities from the contact part with a floor surface and thus the smooth area is 50-60% of the total boot sole area, the total edge 2 length of a sole design pattern being set to be 1,400-2,800 mm. |
