The Men's Simms Vibram G3 Guide Boot is a 2024 award-winning boot for grip and confidence in the river. Fly fishing requires support and trust when wading into the water, keeping you upright so you can focus on placement. The durable construction features high-abrasion textile mesh, plus synthetic and natural rubber, as well as scratch rubber overlays. Finished with the Vibram Idrogrip outsole with Traction Lug, you'll barely notice the slippery rocks under the water.
