ok you river fishermen, I ended up just getting a new pair of neo waders form cabalas 5mm, I have wading boots in felt. my question.... I fish on rivers full of river rocks and lava rocks, these things are so slimy and the felt soles are the only ones ive found that give me the grip I need to feel safe... with tall the new stuff out there is there something else I should look at? im not worried about transporting things via felt cuz I don't jump to other water systems with same boots. any good boots I should be looking at? I have frog togs with felt right now and I like them.
