At the time, for the mold 10, the one provided with the pushing clearance 11 of the bur suspension part 411 on a mold inner side for forming a bur suspension part housing groove 12 for housing the bur suspension part with a margin at an upper peripheral edge 10a is used. Then, the mold 10 and a side mold 30 to which a last hanging an instep strap is fitted are fitted together by forming a clearance 60 for molding the upper sole and the clearance 61 for molding the upper sole bur and tightly sealing the fitting clearance 50 of the mold 10 and the mold 30 with the bur suspension part 411.
