I've had my Sidi Genius' for about 5 years and have been wondering if it's time to replace them. They're in pretty good shape, insoles replaced to hopefully cut down on the stink, etc. I know that running shoes have an obvious life to them and would guess that cycling shoes do to, to a degree (obviously the stresses that running shoes are exposed to is different than a cycling shoe). I would guess that the soles, especially the nylon one on my shoes would lose stiffness over time, but hey, maybe I couldn't even tell the difference. Just wondering what you all do with your shoes...........wear 'em to the ground or replace every so often?
