I too have 'bad feet' and wear orthotics in my shoes. I never put them in my wading boots because I was afraid of ruining $300+ of orthotics.

Now you've got me wondering if a pair of insoles would help. I'm curious if you put them in the boot directly or if you put them inside your wader sock?

And as a side note - Gorilla Glue works great to repair a pair of wading boots that are coming apart... (I'm disparately hoping my pair will last until there is a new and proven generation of something that replaces felt for stability but doesn't contribute to spreading invasives.)
