Replacing the small, wear-prone parts on your Sidi shoes gives them a whole new lease on life, and Sidi makes the process pretty easy by offering things like the Tecno 3 Push Buckles for a palatable price. If you're wearing shoes from that use the Tecno 3 closure system, keeping one (or more) on hand will help you avoid buying a new pair of shoes in the event that a brush with asphalt tears your current buckles off.
