The HEXAGRIP™ Alloy Cleat & Carbide Stud Pack contains everything you need to fully cleat and stud a pair of Grundéns Vibram™ wading outsoles. We designed our outsoles to accept both Hexagrip™ 19mm alloy cleats and ¼” Hexagrip™ carbide screw-in studs in an under-foot pattern that optimizes in-river traction and durability while maintaining Vibram™ rubber contact in critical traction zones.
