A final tweak:
I have been dealing with an increasingly painful toe joint problem- on the right foot, when the toes are dorsiflexed (pulled upwards) and the foot loaded, the second toe metatarsal-phalangial joint hurts a LOT.
I had the bright idea last week to stiffen the Hokas further with a steel insole to keep the toes from flexing. With a bit of help from my pal Al, I soon had a dxf drawing and last Saturday Fred Nelson cut it for me at on his CNC plasma cutting machine at his shop in Azusa. It worked! A bit heavy, but definite improvement.
Monday I visited the doc to make sure the darned toe wasn't broken and to find out just what was going on with it. The diagnosis: No hint of a fracture or Morton's neuroma, just synovitis; the prescription: A carbon fiber insole to keep the toes from dorsiflexing!
I pulled out the steel insole and the doc had a good laugh, telling me that was old school, how they treated this problem before carbon fiber composites!
It works great and is much lighter than my steel prototype. Here is a photo of the generations: Hoka far left; Plastic insole first try left, steel- middle, carbon fiber, right.
