What shoes will the cleats work with?
The type of shoe you have determines which cleat you need, not the pedal model. Mountain bike shoes with knobby souls and 2-hole bolt pattern use the Premium Cleat. Road shoes with smooth souls and 3-hole (also known as the delta) bolt pattern require our 3h Cleat http://crankbrothers.com/3hole_cleat.php?itemId. Both of these offer the 6 degrees of float. If you are using a Quattro pedal with road shoes, you can achieve a fixed (no float) fit with the fx Cleat.
