Simms G4 BOA Boot

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 hard wired for warmth and comfort, featuring a lined neoprene finish, cushioned where you need it most and ultra-smooth for easy on/off performance.

Please note
We display and sell all our boots using the UK Shoe size on Angling Active. When purchasing from this page you will be choosing your desired UK shoe size.

Simms recommends choosing one size larger than your normal shoe size. This allows additional room for the neoprene stocking foot wader.
For example if you normally take a UK8 then you should choose a UK9 for the best fit.
