yes, Finny.
it's usually my right ankle that collapses outward, and my right foot that's floppy.
but about 15% of the time, presto-chango, my left side goes all wonky on me.
so, I have two AFOs.
very simple ones, soft cloth, with a bit of hard plastic side-bracing, and velcro closures, pretty easy to deal with.
the AFOs even fit inside most of my shoes.
I only wear them when I have to go out, and walk more than two hundred yards, that's when it kicks into gear, as I grow more tired.
it's especially 'active' if I have a virus or bacterial infection at the time.
hope yours resolves soon, dear!
