Simms HardBite / AlumiBite studs & cleats add bite when slick rock, algae and current push your limits. Choose the variant that matches your boot sole and conditions—Simms rubber-soled boots with Vibram® outsoles accept star cleats and rubber-stud kits; felt soles take the felt-stud kit. Use Simms’ compatibility chart to confirm your boot model.

Proven Performance Traction

Star cleats key into pre-defined locations on Simms Vibram® platforms (RiverTread®, StreamTread™, VaporTread) and use either aluminum (to conform to rock) or carbide chips (maximum bite). Stud kits for rubber or felt soles use hardened screws with welded carbide pellets for durable traction you can trust. 

Simms HardBite / AlumiBite studs & cleats will solve your traction problems.

FEATURES

• Star cleats fit pre-defined Vibram® locations on Simms outsoles
• Stud kits (rubber or felt) add welded-carbide bite for slippery substrates
