I could see that sort of thing happening to me -- when I tried to add a metatarsal button on top of the insoles in my bike shoes last year, I ended up in more pain than I had been without them. And a few years ago I tried new Shimano insoles in the bike shoes that caused all sorts of leg pains, because it changes the angle of my feet ever so slightly.

But at least now you know what caused the problem and are on the road to recovery.
