After several rides with the Specialized insole I am very happy with its effectiveness. The old Adidas insole that came with the shoes was simply worn out and flattened to where it was just taking up a few mm of space. The fitted Specialized arch is specific for someone with high arches like I have and it has done the support job well. It is not overly thick anywhere, a big point with me.

Now to check out the Superfeet insoles that Terex recommends, the insoles are worth the effort to get right, and I fully agree with not using the Dr. Scholls products for cycling, did not work at all, too flimsy, you get what you pay for.

And for the OP, I'll second all calls for getting the bike's fit correct, be it by a professional or your own doing with one of the books or the BF forum, it is worth the effort. I had pain on the inside of my left knee at the patella back in 1979, one of the old guys in our club watched me while riding and took me aside and helped me adjust the seat height and its fore/aft position, a slight lowering and moved a bit forward and it was fantastic. I was sold on a correct fitting right then and there although no one called it that back then.
