Yes, I think high-top shoes could really help with that. I have a similar problem and the only reason I don't wear high-top shoes is that the shoes I need to wear for my heel problems don't come in a high-top variety, which is annoying.

As for facebook, it's evil. I wouldn't bother putting your energy into posting on there. Same goes for Tumblr, but for different reasons. In the case of facebook, I could easily imagine you running into people of a certain political persuasion who will gaslight you and pretend your problems aren't real. In the case of Tumblr, I'm afraid people of the opposite political persuasion might at first accept you, and then eventually tear you to itty bitty pieces over small stuff, since there are way too many SJWs on there who don't know when to give people space.
