Toes insert

Hi. I have very strange toes. Does anyone know of stiff toe inserts for rock shoes, please? Like an insole, but just the toes. And stiff. Or a material I could use. I guess it would need not to cut into the base of the toes? Thanks 

There was a thread earlier this year that mentioned carbon fiber inserts. Super thin and esay to trim with scissors.

I have a pair of these. Available on Amazon. The felt can be easily peeled off if the plate and the felt together are too bulky.

There are resolers that can add a stiffener as a midsole.
