I had terrible problems with my right leg. The pediatrician made me new orthopedic insoles. But my other Brooks (The Beast) shoes that I loved for many years just didn't match the new orthotics. I had terrible pain in the tip of my toes. I took a chance and tried the Dyad with the extra width and now I have a second pair and after a year I am foot pain free and enjoying my daily walks/jogs.
