On the Chattahoochee tail water there are sections where you are wading on rock and moss and sections where you are wading on dirt. A lug would probably work better on the dirt and felt on the rocks. I have done a little wading in the black water creeks of south Mississippi where the bottom is sandy. The ideal shoe is going to depend upon what the bottom is where you are fishing. I know felt is slick on dirt and rubber is slick on rocks.
The inherent vice of capitalism is the unequal sharing of blessings; the inherent virtue of socialism is the equal sharing of miseries. Winston Churchill
