When fishing in a fast moving river you don’t want the river to send you down stream. The Patagonia River Carmpons are worn over wading boots and offer traction in fast moving river currents. The aluminum treads are reportedly sharp enough to cut through river slime while still being able to dig into the riverbed. These are removable and fast-drying as well, but best of all ensure that you don’t end up being swept away by a river that runs through it.
