Actually that isn't all. About 3 months ago I switched to the entry level Specialized road shoes from mountain bike shoes. The shoes combined with Speedplay X pedals have virtually eliminated my knee pain. I did find that I had to go up one size in the shoes (I normally wear a 36) but this allows me to use slightly thicker socks. I can really tell a difference in the angle of my knee when wearing the Specialized shoes with the wedge design.
