I woke up in the middle of the night and then had difficulty falling back to sleep. That turned out to be a good thing. Among the many thoughts that wandered through my brain while wide awake at 1 a.m., I realized I hadn't yet glued Velcro to my new shoes.
I always wear Dirty Girl gaiters to keep sand and pebbles out of my shoes. A small strip of Velcro is necessary on the heels to hold the gaiters in place. The Velcro that comes with the gaiters has an adhesive back, but that's never sufficient to remain stuck to the shoes. A small amount of super glue takes care of that problem.
I got out of bed and glued the Velcro strips to my shoes, then went back to sleep. By taking care of that now, there was plenty of time for the glue to dry.
