Teresa Ullman LOVES LaceLocker®. "First off, I was confused on how to put Lace Locker's on, but the instructional youtube video was absolutely fantastic! My laces stayed in place!!! And my #1 love of these . . . They helped to keep the tension on my shoe! Meaning when I took a step on the trail run, my shoe didn't slide to the right while my foot went to the left! It helped to keep the happy tension of the shoes on my foot! WAAHHHOOOO!!!! 2nd best thing! I did not have to scrap, scrub, no wash caked-on dirt from my laces! 3rd!!! The dirt wipes off, the mud wipes off really well from the Lace Locker®!
