Zinnia,

There is an external lift I used when I was in a cast boot. It is called an Even-up and they sell for around $20 on Amazon. It attaches to your athletic or lace up shoe and has two different levels so you can adjust. Nothing else to cram in your shoe. I liked it. It kept me from walking so much like Captain Ahab.

If you can't lace normally you might consider going up a half size. I found I needed a special gel insole for a long time that just required extra room. That little bit of Cush made a big difference. I think Swimtime's son had a similar issue. Sometimes those little things really do help.

PT for just a handful of sessions for gait analysis and training sounds like a good idea. Optimize your outcome wherever you can.
