My daughter LOVES these.  This child is allergic to trying her shoelaces, so these laces are a Godsend!  They are super cute (rainbow) and are more adjustable than the other brands we have tried.  I may try a pair, since I have wide feet, and some of the other laces have been too snug. They have been worn for a month now, and they have not come loose or untied yet, and my daughter LOVE slipping on her shoes in a flash!
