I have to say that I was more than a little skeptical when buying these laces. After easy installation, they are performing nicely! My new running shoes are even more comfortable and are now slip-ons! I left a little extra on the "tail" of the laces to allow for easy adjustment. I am interested in seeing how these hold up over time, but for now,  I won't hesitate getting a few more sets for other shoes that I own. Well done, Lock Laces!
