After a few near dives of less than 1.0 difficulty on the slippery rocks of my local stream something was trying to tell me that my felt bottomed waders are no longer viable. Was wondering how many folks have tried replacing the felt by gluing new stuff on as opposed to just trashing the waders and getting new ones? Do they hold up for a decent period of time? Waders haven't sprung any leaks and I like the chest high pair; so, would really rather keep them. But, don't need a repeat of a few years ago in hip huggers when I fell and destroyed what was left of an old football knee. That cost me the best part of the season and a long rehab. Thanks for any suggestions.
