Look KEO Cleat Shim

This shim is designed to add 2mm of stack height between your shoe and the cleat. It is primarily used to address leg length discrepancies or to fine-tune biomechanical alignment for a more efficient pedal stroke.

No, these are specifically engineered for the LOOK KEO pedal system. They will not fit other cleat standards like Shimano SPD-SL or Speedplay.

While it is physically possible to stack shims, doing so can compromise the security of your cleat bolts. If you require more than 2mm of adjustment, consult a professional bike fitter to ensure your cleat bolts remain long enough to safely engage with your shoe.

In most cases, the standard bolts provided with your cleats are sufficient for a 2mm shim. However, always check that you have enough thread engagement—typically at least 5mm—before riding to ensure the cleat remains securely attached.

Typically, you only install the shim on the shoe corresponding to the shorter leg. If you are using the shim to correct a specific biomechanical issue identified by a professional fitter, follow their specific guidance on whether one or both sides require adjustment.
