hi there
you might like to get yourself some toe crest pads to help uncurl your toes. You will walk and balance better with them.
I have curled up toes, but mine is due to spasticity rather than tendon tightness. I can uncurl them with my fingers, but they curl right up again when I let them go. I have sensorimotor PN, so I think the PN has indirectly caused the toe curling because the muscles in my feet are very weak, and weak muscles are prone to spasticity altough spasticity is a central not peripheral thing.
Here is a link to toe crests - I have not used this particular brand, I just want to show you what they are. It takes a little while to get used to wearing them, now I don't even notice they are there.
