    Shimming Shoes.

    Hey guys, maybe yall can help me here, just got my first road bike last week as well as my first pair of pedals, cleats, and shoes. I need help with one thing, I was born with one leg longer than another to the point where my right leg was 7 cm longer. i had a surgery ten years ago and they were able to make my right leg shorter by 5 cm. that leaves me with about 2 cm difference still, I dont wear inserts normally anymore. I was told by a friend that i should have my shoes shimmed and maybe also have inserts added too. I definitely feel a slight loss of power as well as some discomfort on a 33 mile ride i did this weekend. Anyone have experience with this? Maybe point me to the right direction? Any help will be greatly appreciated. Thanks for all the great posts here!

    Three things are normally done in concert: Shim the cleat about 1/2 the leg length discrepancy. Move the cleat forward on the shorter leg 0.5-1.0 cm compared to the longer leg. Rotate the saddle nose a few degrees away from the shorter leg.
