Shoe laces as we know them are hundreds of years old. And they haven’t seen any innovation since the addition of aglets (the plastic things on th ends). For the most part, they work as needed for day-to-day wear. But for athletes who perform in events like triathlons, marathons, and endurance events like Tough Mudder, something that guarantees performance is required.
Lock Laces are made of stretchy bungy that allows give during natural motion while retaining tightness. Regular shoe laces are rigid, and if they do give, they stay loose.
Lock Laces are also fitted to your shoes and how you wear them. Once installed, you never have to worry about floppy bows or having to stop and tie your shoes during your timed event.
Skeptical? Don’t take my word for it. My girlfriend used them during the Warrior Dash and gave them glowing reviews.
It’s the closest thing to power laces that we’ve got.
