I tried to cheat the Brooks dyad with the new 1080 balance they didn't do it for my knee point pain. I've been a Dyad fan since Series 7, Dyad fans were disappointed with the narrow toe box in Series 9 - I just increased the size to compensate. I wear size 4e and love it. I have wide flat feet ((Fred Flintstone style)) no pain in hips, back, knees. Brooks executives, if you have wide feet, chances are your toes won't magically narrow.
