Confident footing is imperative for presenting flies well when you're in the water. The Simms Tributary Wading Boot can help you find a good spot in the river and maintain confidence in your casting. This rubber-soled boot conforms to the rocks underfoot, and is compatible with studs for additional traction if you find you need it. The upper is made from a fast-drying synthetic material which helps you hike without excess weight, and a neoprene lining that provides insulation for your extremities.
