SOLE AND MANUFACTURE OF THE SAME

摘要

PURPOSE:To prevent any lacked part at an uneven pattern part on the ground face of an outsole. CONSTITUTION:The injection molding of a polyurethane foam is executed onto a boundary face between the outsole and a midsole 12 so as to provide the uneven part along an uneven pattern part 14 formed on the ground face of the outsole. In the case of injection molding, pressure is almost equalized, air is distributed at the corner parts of the uneven pattern part 14, and no lacked part is generated at the uneven pattern part 14.
