Abstract: Disclosed herein is a shoelace tightening device for making it easier for the wearer to tie shoelaces of shoelace-type shoes, including sports shoes. The shoelace tightening structure comprises a tightening lace, a pair of locking devices, and a shoelace. The tightening lace is successively threaded upward at both ends thereof through first and second row loops arranged in parallel along eyelet lines defined at left and right vamps of a shoe. The locking devices are fixed at opposite side positions above the eyelet lines. Through the locking devices are inserted both the ends of the tightening lace, respectively. The shoelace is tied on the tightening lace as both ends thereof alternately pass through portions of the tightening lace between the respective first row loops, and portions of the tightening lace between the respective second row loops so as to crisscross each other.
