Missed this!
High vs low....depends on application and player. I cant jump in anything but a basketball shoe and while i dont have ankle issues, I dont "trust" low tops very much. Played in Kobes, KDs, 2015 Hyper Revs, etc...I can and have had no issue but subconsciously I have some issue with it.
As for the rehab stuff... soreness is ok sometimes. Its the muscles getting used to being used again. Pain is usually not ok. Have you tried just doing nothing for a few weeks then doing a few weeks of strict rehab lifting (low weight, medium/high reps to promote healing)?
I had a month break, then I took it easy for a while. After a bit, I went on vacation for a few weeks but after I went into playing pickup right away. Actually, theres very minimal pain, guess its mostly soreness. Will still get it checked out though.
Also for high vs low, my opinion on it is that it shouldn't affect one foot jumpers because they seem to get minimal dorsiflexion when they jump off one foot. I can see it affecting quad dominant two foot jumpers though. The more quad dominant, it seems that the more dorsiflexion you get.
