Here is The Official U-Lace Lacing Guide and Instructions.
U-Lace transforms your sneakers into masterpieces. U-Lace has 56 hot colors to let you create whatever look you desire, whether you want to rock single-color lace-ups, or multi-color laces-ups in school or team colors; hook-up colors; cheer squad colors; fresh fashion colors or dance troop colors.
U-Lace works best on 3-piece construction sneakers.
Push tip thru eyelet; closed end first. From inside the sneaker pull the aglet thru. Align aglet so open end (fingernail) points toward toe.
Pull the U-Lace tight and into place from outside. Stretch to next eyelet; whichever you choose. Insert as before. Align aglet with open end (fingernail) pointing towards toe. Take fingernail and lock them over the aglets of the segments below them.
If your sneakers are looser than you like try a pattern that will stretch the U-Lace’s more during the lace-up. This will yeld a more snug fit.
