SOLUTION: Rods 40 of male screws with round bases are inserted from the rear side of an instep part 60 in parts or all of the holes for putting a shoelace 50 therethrough provided in the instep part 60 of a laced-shoe. Holes for inserting the rods 40 of the male screws provided in a plurality of washers 20, 30 having holes for putting the shoelace 50 therethrough respectively are inserted into the rod 40 of the male screw projecting from the front side of the instep part 60. In this case, the shoelace 50 is pinched between the both washers 20, 30. Then, a female screw 10 is fastened to the projecting end in the rod 40 of the male screw to fix the shoelace immovably. This constitution can appropriately set the fastening extent of the shoelace 50 according to the respective positions in the instep 60 so as to surely prevent the shoelace 50 from loosening even in a case of taking hard exercise such as sports. |
