My LLD is >1 inch (closer 1.5) and is in the femur bone. When I cycle longer distances, the hip of my shorter leg starts to hurt. I have tried heel lifts in shoes but I can only lift to I think half the distance without having to completely modify the shoes. I am thinking of getting cycling shoes then custom orthotics for them but again, i'm not sure if that is possible.

I read previous posts that spoke of custom crank sets. Is this method very expensive? Do they shorten the posts the pedal is connected to for the shorter leg or is it a complete rework of the crank set?
