I wore my favorite long time hiking boots for a winter walk last week. The lace from the left got caught in a hook on the right, and down I went! Not even enough time to get my hands out of my pockets, so used my chin to break my fall.
Fortunately, it was very slushy out,
which lessened a direct impact, but added to the amount of dirt and
road salt going in my mouth and face.
I understand newer boots don't have these metal hooks anymore. Maybe
it's replacement time?
