I wear felts with studs. I'm not sure studs or cleats are bad but I think the way one wades is most critical.
Wade slowly, then slower than that, then slow it down even more. My goal is to make no ripples. A friend of mine, and instructor at well known fly fishing/casting school, is the finest fly fisherman I ever fished with and looks like a Blue Heron on the water.
He waits for over an hour on the bank watching the fish until the right moment just before sunset. The "Magical Minute". He would then wade into the water. S l o w l y...no ripples, no sound, no motion, would catch a 20"+ fish with one cast and then go home. A dry fly, one cast, perfect presentation, perfect drift then BAM! That was his goal. And, those fish are not stockers, they are serious PhD trout on a famous river in the Catskills. They are notoriously difficult to catch. I've seen him do this on more than one occasion too.
Try as I may I can't equal his skill, but I keep trying.
