One of the things that I do as part of my morning routine is the yoga tree pose for a bit on each foot. Why this one? Because my balance isn't so good, especially on my right foot. I offer two speculative reasons for this:
- I have no arches. I have an outstep where most people have an instep. My feet will, if sweaty or damp, make suction on smooth surfaces. It's a neat party trick, but it also means that the muscles, nerves, and connective tissues from my ankles on down aren't exactly nominal.
- I sprained my right ankle repeatedly at the end of the last century and didn't do physical therapy for it. I think this explains the asymmetry.
