ALMOST had a tip over today when I stopped at a light. My left shoe string had gotten tangled into my shifter lever. I went to put my foot down and suddenly could not free my foot and put it on the pavement. Luckily and quickly I shifted my weight and cheeks off to the right side of the bike and touched down there while wrestling the bike to stay upright. The shoe string entanglement was not bad. It was just unexpected to the point it could have been problematic and certainly got my attention quickly.
