This cleat offers five degrees of heel float and 2.5mm of lateral float along the pedal axle. It's compatible with all three-hole road shoes, but the included shim may be required for shoes that have a large curvature in the forefoot area. The RXS cleats works with all RXS and Impact pedals that were part of previous model line-ups, this is the replacement cleat for those pedal platform systems. Made of a thermoplastic construction.
