I can't believe the athletic shoe industry hasn't switched over to this type of lacing! The most irritating thing about lace-up shoes is that they're constantly coming undone. Lock Laces don't come undone. They also make most sneakers slip-ons (almost) which means you can convert other pairs instead of buying new shoes. The other advantage is that they can be custom fit to any shoe or foot. I have a narrow foot and almost every lace-up shoe I buy has lots of left-over length dragging around when laced. I have to buy new laces anyway. Might as well get these. It's not easy to remove the end clip if you your shoes are worn out and you want to transfer them to another pair, but it can be done. On the negatie side, the laces are a bit stiff, and I would like some more color choices. Not much to complain about.
