#I'm from the US but due to a pesky ankle spraining habit have consistently done weird ankle mobility exercises often over lifetime

I can but I had to practice at it which seems like it doesn't fit with the other information in the post. Maybe for me my bones can do the thing but I had to more work on the balance of it.

According to a cursory Google search most people can learn to do it with practice at staying at that instep to shin angle. But it's a pretty broadly used position globally, I taught myself to be able to do it comfortably bc it is super convenient for field work on a vessel once you've got it down. There is a part of me that was determined to get it bc I hate the like haha dumb Americans can't do x of it all.

Anyway don't give up if you feel like you can't do it initially, you might be able to practice until comfortable!
