Unless you are in an area where cold is not such a problem.

Kevlar and carbon fiber are expensive and would make the shell too rigid. It would cost more for materials that to buy new high end shoe covers. But you might try combining scraps of ballistic nylon or cordora with the pantyhose trick.

I still think that you are not going to accomplish your waterproofness goal at the ankle joint by this method.
