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.

SOLUTION: A fastening element 30 is formed of a base bottom part 32, angled struts 33, 34, and a substantially spiral structure 36. The spiral structure 36 comprises a hook part 37. The fastening element 30 is used as a fastening mechanism for shoes. Thus, the base bottom part has a width W1 of about 24mm and a height H1 of about 15mm. The whole length L from the lower end of the base bottom part to the upper part of the spiral structure 36 is about 37mm. The width of the spiral structure W2 is about 16.5mm. An opening part 38 preferably has a diameter of 3.5-7.5mm so that a shoelace can be easily passed. The fastening element 30 is formed of a thermally molded linear part consisting of a semi-hard plastic material or high density plastic impregnated with rubber, which is manufactured from high density polyurethane or the like.
