I use a pair of Keen Gorge boots for wet wading and paddling. They are a mid height neoprene boot. The soles are pretty good for our mud and flat rock streams. I think I would opt for my regular wading boots for rocky streams. The ones I've been in, Tennessee and Michigan, I wear waders... I must have a different definition of cold water than some.
