Foot slap

I have a pretty good case of this, pretty damn noisy walking in the tiled halls of airports. I should be able to go to any physical therapist in the world and be able to get EXACT STROKE PROTOCOLS to correct this problem. 

The standard explanation for this is lack of dorsiflexon. Not for me, I can dorsiflex just fine. According to my analysis it goes back to the fact I don't have a free swinging lower leg .  Initial, mid and terminal swing don't exist due to spasticity. I swing my leg like a log.  Fix my spasticity and I can recover normal walking easily.
