The Simms G3 Guide Boot is the ultimate wading shoe for all of your fly fishing adventures. The Simms G3 Guide Boot offers the most support and protection for rock-strewn trout streams like the Madison River or smallmouth bass rivers like Wisconsin's Flambeau River. This is the most durable leather shoe that Simms makes. Fly fishing trout, fly fishing bass, fly fishing muskies, steelhead and anything else is much more comfortable in the Simms G3 Guide Boot. Simms’ G3 Guide™ Boot has blazed more miles than any other wading boot in existence—and it’s just warming up. Advancements to this year’s incarnation include the guide-approved performance of a RiverTread platform featuring proprioception, which minimizes rigid underfoot materials for enhanced feel whether on the trail or in the water. Vibram® Idrogrip outsoles add to this great-grip equation thanks to multi-directional lugs—compatible with all Simms’ AlumiBite™ and HardBite™ cleats and studs. Additional features include a TPU molded heel clip for a positive, locked-in fit, as well as neoprene internals that deliver cushioning where it counts for superior wading warmth, comfort, and easy on/off activation.
