Sheesh, does your big toe move the same amount as the other side. When you bend it backward it should bend to almost 90 degrees. If it's stiff this may be a problem.

I just bought a pair this weekend to help with a toe issue. I got the slip on kind tho. They're hard to get used to but really cool and I think they'll do the trick.
