If you don't have a pair, I encourage you to get some!!
"My review of LaceLockers®. Went out on a 5k today with these, and they did great in keeping laces tied just like I started with on my run!! The Velcro® closure locks laces in place so no slippage occurs! If you don't have a pair, I encourage you to get some!! Well worth it, and you don't have to stop mid- run to tie laces back up!"
