I've had a knotty problem lately...it's my shoelaces. They don't like to stay tied when I'm running. I tie them snugly before I leave the house, but eventually they work themselves loose. I stop my run, re-tie them, get my not-so-svelt frame chugging forward again, and run awhile longer until the problem repeats itself. Uff da.
I found an interesting video on the Runner's World website. So-o-o...I'm going to give this a try...that is, if I can un-learn the way I’ve tied my shoes for the past 45 years. I'll keep you in the loop on how it goes.
