I'm not gonna lie...In my experiences in wading felt soled boots/waders are 10 times above and beyond typical rubber soled waders even the ones with rubber cleat like studs on them. The felt has amazing grip WHEN WET, if they are dry on grass or something as your gettin into the water they are SLICK! and you can bust your butt out of the water!..but once you get in and get the felt wet they are like super glue very very good grip!...for me its no question I use felt soles now and always.
