These are the most extreme high-heels you can imagine. Basically, keeping the foot in a ballet on-pointe position the entire time. Of course, here there are also some different variations. To increase the walking difficulty even more, one could use ballet heels, that don’t even have heels. Of course, this requires a bit of a different positioning of the foot. A fantastic use of this within a story, which I sadly haven’t seen frequently, is when a person wants to cosplay / dress up as someone who’s actually quite a bit taller. They use a kind of fixed sock, that keeps their feet in that position, and then wear normal boots over that, to simulate a taller body.
