The Korkers Men's Devil's Canyon Wading Boot sets a new standard for technical and athletic fishing wading boots. The Devil's Canyons feature the OmniTrax 3. 0 Interchangeable Sole System so you can adapt your traction to meet the performance needs of each river system. We are offering two sole options: felt and Kling On rubber outsole, or the Kling On rubber outsole and the studded Kling On. You can purchase other outsoles separately for maximum versatility. The non marking Kling On outsoles are also safe for all boats. Korkers also gave the Devil's Canyons a low profile Boa MT2 speed lacing system for a quick on and off and a snugger, more comfortable fit that won't loosen up as the day goes on. The lacing works with the close fitting boot cuff to offer excellent ankle support. Made for those who are constantly scouting out the next hole, the Devil's Canyons' tough 420D RockGuard synthetic materials supply stellar durability and longevity for technical wading boots that last. Plus, the hydrophobic waterproof materials reduce water absorption, which reduces overall weight and drying time to help prevent the spread of invasive species. Fewer stitched seams improve durability and eliminate potential failure points with the 3D EVA molded toe caps. Regrind rubber toe caps provide an added layer of protection without adding weight while integrated midsole drainage ports allow water to drain quickly to keep the boots lighter while you wade. Lightweight and nimble, these durable wading boots fit like a glove and keep up with your on the move approach to fly fishing.
