FORM Speedplay Leg Length Shims add 2-5mm of stack height between your cleat and shoe to correct leg length discrepancies, helping balance your leg extension and stabilize your pelvis. Signs you may need them include overreaching on one side of the pedal stroke, uneven saddle wear, or feeling like one leg is under-extended while the other feels right.
Features & Benefits
- Made from impact-resistant nylon to reduce damage due to repeated clip-ins
- Can be combined with FORM Speedplay Cleat Wedges easily to optimize individual comfort
- Creates a more equal leg extension
- Stabilizes the pelvis
- Establishes a smoother and more controlled pedal stroke on the shorter side
- Reduces pain and discomfort
- Kit provides 2mm, 3mm, or 5mm of lift (combination of shims)
Leg Length Shim Usage Criteria
Leg length shims are used to increase the effective leg length of a shorter leg in cases where a cyclist suffers from a leg length discrepancy. Signs of a discrepancy can be:
- Overreaching on one side at the bottom of the pedal stroke
- Pelvis tilted or rider leaning to one side of the saddle to retain connection with the pedals (many times this is apparent in saddle wear on one side more than the other)
- One leg feeling under-extended whilst the other feels just right
Assuming a rider has been assessed to have a discrepancy, the issues above could be solved with the use of leg length shims. Leg length shims are also sometimes described as lifts or adding "lift."

The worked as designed, excellent quality.
Decades of rocking in the saddle, screwing up my spin are now gone! I had recently started seeing a chiropractor for upper back & neck pain. From the x-rays taken during the initial exam, I was informed I had about a 4mm shorter right leg. That exploded the light bulb in my head as to why I’ve spent decades having a jagged spin even though my on-bike setup seemed bang on. I told the chiropractor about that issue & told him I was going to research a shim for my cleat. He suggested no more than a 3mm shim.
My research led me this product and I have to say, my spin is no longer wonky & is now smooth as butter without any discomfort in my hips!!
Thanks for the great, inexpensive solution!!
