are you overanalyzing? get it checked by a pro.. don't try and diagnose stuff like that on your own tbh.
i notice lots of people "overanalyzing" feet/ankles much more in the last 2 years or so, ever since it became more hyped up by the foot gurus and such.
we used to do this subtalar release bullshit at some performance facility I interned at, this was in 2008 .. this dude was ahead of alot of people in terms of what's all the "buzz" lately.. but, alot of it was horse shit. He had interns performing this subtalar release technique on people, who really had no idea what they were doing. It looked so damn fancy and magical to the clients/athletes though.. "wow these guys are restructuring my ankle joint!#!@$@", no, you've just been played.
