In my local area (Rocky Mtn's) there are streams with very slick algea covered rocks and water fast enough to be dangerous. Several people die each year during the run off. As a result I fish with felt soles and steel cleats.

The cleats are less comfortable on long hikes, kind of like walking with a stone stuck in the sole of your shoe. No one will let you into a boat with cleats, so I also have a plain felt pair.

The felt will pick up snow (not a big problem where you are I suppose) and can be very slick on muddy spots.

I have yet to see a rubber sole that can stick to wet slim covered rocks the way felt can. I have seen some boots with a rubber sole that has felt patches inset into the heel and toe.
