The Leg Length Shim (LL Shim) Variety Pack comes in a Poly bag containing one of each LL Shim:
- Universal (Look Delta, Time Road, Shimano SL)
- Look Keo
Leg Length Shims (LL Shims) are used to compensate for leg length discrepancies. The SPD, Universal and Look Keo LL Shims are 3 mm and made of high-density plastic to conform to the curve of the sole of the shoe. The Speedplay LL Shim is 3.5 mm.
