Central Montana is home to cowboys, roughnecks, and fly fishers, all with three defining traits—spurs, steel toes, and Simms. For those occupying the latter category, Simms’ G3 Guides™ raise the bar with a RiverTread™ platform bolstered by proprioception, which minimizes rigid underfoot materials in order to enhance feel whether on the trail or in the water. The felt G3 combines all-day wading comfort with the angler-appreciated underwater traction of a 12mm felt outsole, compatible with all Simms’ AlumiBite™ and HardBite™ cleats and studs. Additional features include TPU molded heel clips that lock in fit, while the neoprene lining stacks cushioning where it counts, keeping feet warm and delivering easy on/off performance.

• A 12mm felt outsole version of the Guide Boot for a lighter, yet more durable balance of wet trail & all-day wading
• Simms NEW RiverTread™ platform for guide-ready wading comfort, support & traction
• TPU molded heel clip for positive heel fit & hiking security
• Partially-lined with neoprene for wading warmth, cushioning & easy-on/easy-off

MATERIAL TECH: Waterproof nubuck leather & TPU-coated textile RiverTread™ platform/12mm Felt outsole


The New RIVERTREAD™ platform is designed for the demanding angler looking for the best wading footwear on the market. RIVERTREAD™ features Simms’ latest engineered components to maximize comfort, performance, and slip-resistance. The molded 3D footbed with arch support and ball flex aligns the foot for all day comfort and optimizes biomechanics. Molded dual-density EVA midsole creates extra cushioning for hiking comfort and enhances proprioception. A Molded and minimal TPU rentention plate allows lightweight cleat retention and enhances proprioception. A molded Vibram® Idrogrip® outsole with 4mm self-sharpening multi-directional lugs permits long lasting traction on trails, slip resistance in water and toe protection. Also available in a 12mm Felt outsole.


CleanStream™ is a design philosophy that runs through the Simms line of wading footwear. While not specific to a product feature, this designation does indicate that the product includes features and/or materials that are more resistant to "hitch-hiking" organisms – have less exposed stitching, fewer ridges & pockets and utilize non-absorbent materials – all making the boots easier to inspect, clean and dry faster. All of these elements assist anglers in doing their part to prevent the spread of invasive species.
