Step into Simms’ G4 Boa® Boot and elevate your fishing experience thanks to an asymmetrical Boa® system that delivers an articulated, secure fit over and across the instep. Underneath the G4 chassis you’ll find an advanced RiverTread™ platform that minimizes rigid materials in exchange for maximized proprioception—your ability to feel and adapt to an ever-changing underfoot environment. In addition, Vibram® Idrogrip outsoles provide great grip across slick underwater obstacles via multi-directional lugs—compatible with all Simms’ AlumiBite™ and HardBite™ cleats and studs. Inside the boot is an environment hardwired for warmth and comfort, featuring a lined neoprene finish, cushioned where you need it most and ultra-smooth for easy on/off performance.
