I have been a long-distance runner for years, and
after a spinal injury, I was left with nerve damage resulting in permanent
foot drop. I have tried every AFO, excercise, treatment, etc. that my orthotist could think of. I finally had to seek out answers on my own. (For the full version of my story if you have more interest, this is truly the nutshell version - http://****.blogspot.com/). I didn't want a bulky, sometimes painful AFO.
