curled toes failure

 I've been wearing a toe crest for the past 15 years. My second AFO had a built in toe crest and when I quit wearing that 3 years in I had to figure out for myself what it was called and where to get one. Three years was not enough time to stop the spasticity in my toes.  A couple months ago I stopped wearing one since I thought I didn't need it. All was good until this past weekend in Pittsburgh for the Frozen Four. We walked a lot on pavement to get to and from the arena and to see the sights. Much less than the common 4 miles I do every day in the woods next to me. But the last day walking back after UMass trounced St. Cloud State I could tell that I was once again walking on the tips of toes 2 thru 4, fairly painful. So I guess 15 years of toe crest therapy is not enough to cure the spasticity in my toes. WHAT THE FUCK IS THE CURE?
