Why Use Leg Length Shims?

Leg Length Shims (LL Shims) are used to compensate for leg length discrepancies (one leg is shorter than the other). Our LL Shims are made of high-density plastic to conform to the curve of the sole of the shoe.  The SPD, Universal and Look Keo LL Shims are 3 mm thick while Speedplay's LL Shims are 3.5 mm thick.

For a 1 mm leg length discrepancy, we recommend "stacking" two (2) Cleat Wedges. To create a stack place two Cleat Wedges one on top of the other with the thicker edges of the wedges opposite each other.
