One time when I was a kid I was at the mall with my mama rocking a pair of K-Swiss and one of my shoelaces came untied shortly before we got onto the down escalator. The ride itself went fine, but when I stepped off at the bottom, the conveyor system sucked up my shoelace! and yanked me back into its revolving death grip. Other people were still coming down, trying to get off, the escalator was trying to eat me alive, I was flailing and yelling, Mama, Mama!--it was a nightmare. Finally, my mama grabbed my foot and pulled off my shoe to release me. She then fought with the serrated barcode beast herself, yanking and swearing and refusing to back down until it released my shoelace. She prevailed. Then we got ice cream.
That day taught me two things: 1) Always be afraid of down escalators; and 2) Always, always double knot your shoelaces. Number 2 is a huge pain. Double the pain of tying them to begin with, in fact. I like these Lock Laces as an alternative. An elastic weave-and-fasten system, Lock Laces were designed to keep your shoelaces tidy and secure.
Obviously, Lock Laces won't come untied in the middle of a race, game, or workout. Or ever. They also make the laborious process of entering and exiting shoes quite a bit easier. And according to their makers, the laces have been engineered for increased comfort and performance, as they reduce typical shoe pressure points and eliminate heel crushing.
Lock Laces come in nearly a dozen different colors, and have been very positively received by over 5,000 Amazon reviewers.
