Ankle Braces of Yesterday and Today

The old ankle braces, the ones in the middle ages, and the ones of today.
A video about the old one was requested long ago by someone and I could never make the video because I couldn't find the brace. It was literally buried in a box of paperwork! Yes. I didn't have enough material to make a video just about that so why not discuss a couple other ones that are a bit more recent?
