Replace your old, worn studs or cleats with the Simms AlumiBite 10-Pack Star Cleat. Specifically engineered to fit pre-defined cleat locations on Vibram rubber outsoles featured on Simms RiverTread, StreamTread, and VaporTread platforms, the AlumiBite utilizes corrosion-free aluminum to conform to micro-surfaces of rocks for superb grip and traction. The AlumiBite may be used individually or in combination with HardBite Star Cleats and Studs (sold separately) in any pattern that the angler chooses to best fit the wading environment.
