Chota's RockLoc is advertised as a special "soft rubber" compound
a supposedly more stream friendly replacement for felt which can
transport invasive species.

I think the felt/rocksnot/invasive species is a bunch of snot. Felt
may very well hold some of the cells and transport it to another
waterway. But, so do shoe strings, cloth material on boots, canoes,
kayaks, etc. And, let us not forget egrets, ducks, mink/otter, deer,
and just plain old Mama Nature.

I have two old sets of Chotas and they are the ones I dedicate to my
travels. I have another set (soon to need replacement) that I dedicate
only to the Rapid.

If rubber soled boots are the way to defeat invasive specias, someone
is will have to come up with a better sole than currently on the
market. BTW, studs are great for wading, but when you are rock
hopping, they are like rollerskates. I took them off my Chotas after
nearly killing myself in some nasty falls. I fall quite well with just
plain old felt, tyvm.
