Even the greatest champions realize defeat from time to time, and a time comes when their dominance is simply over. Similarly, the most advanced cycling shoe on the market, the Sidi Ergo 2 has been surpassed by its successor, the Ergo 3 Vent Carbon Shoes. It has all the same features that made the Ergo 2 such an enviable piece of gear that sponsored pros bought them and hid them under shoe covers adorned with another manufacturer's label. The elemental difference is the addition of venting in the sole to offer selectable airflow into the shoes and four-season comfort.

Sidi re-engineered the sole to allow for the venting. It shares the same construction method that they developed with their Carbon Lite sole, yet they've taken out 38 grams in the process. Even with the weight savings, you'll get the same kind of stiffness and razor sharp power transfer you've grown to expect from Sidi. Like Garneau's Ergo Air system, the vent inlet is at the toe. However, Sidi's system can be opened or closed depending on the temperature and your preferences. This, you can do on the bike if necessary. The airflow moves underneath and through the insole to cool your feet in sweltering summer temps.
