Ankle Injury- Need help finding brace

I have searched all over for a brace to wear while wakeboarding that will help reduce the risk of ankle injury. Specifically something to help reduce the toe coming up too far towards the shin (dorsiflexion).
I found a post from back in July of 2006 and several people commented on the same type of injury.
Search "Talus Injury" to reference that post- it is the 1st one that comes up.
This is a common Snowboarder injury and I have preexisting injuries from snowboarding.
If anyone has found something that works for this or ideas of what could help please let me know.
