I have been using SPD pedals for the past for years. Lately I switched to SPD-SL pedals and new shoes in hopes of relieving some hot spots on the side of my left foot. I've now developed some pain on the inside of my left knee. I've tried pointing the cleats inwards and also moving them to the outside of the shoe, but I've had no relief. The pain isn't bad while riding, it usually flares up later in the day or the next day.

Any advice would be appreciated! I'd hate to go back to the old pedals after investing in new pedals and shoes.
