I'm sure your favorite angler has boots and waders, but this is a place where 1 pair will rarely do. Steve Adachi has often preached to the young shop rats 'if you have one you have none.'

Best Lightweight Boot: Patagonia Forra Boot. They are lightweight and durable, and they are a great pair of boots for anyone looking to save weight or looking for a grippier rubber sole. 

Grippiest option: The Simms Powerlock borrowed from technology from the golf world, allowing large metal pucks to be installed onto a sturdy mountaineering-style boot. I love mine, and lets face it no one likes to fall on their arse.
