This is one of the best AFOs (ankle foot orthoses) I have seen for posterior tibial tendon dysfunction. It is hinged so it allows for some or no ankle motion (basted on how much pain!). The leg part is placed in a varus position for better pronation control. The plastic is wrapped around the arch for superb support. I looked high and high for a manufacturer and could not find one. If you are suffering from PTTD, show this to the brace guy/gal and see if they can do something like this. The foot bed part is pretty standard.
This following link gives you an idea of the brace world, but does not show this exact brace. Rich
