The inside of the boot part of my waders is falling apart... The insulation is coming out and the sole is coming up. The waders don't leak, but the inside of the boot is falling apart. Does anyone have an Idea of how to fix it. These waders are 2 years old, and have been hunted hard. I don't think they're under waranty. So it's either new waders, or fix these. Since they have no other problems, i'd rather try and fix them. Any help appriciated...
