Eagle eyes at the 2012 the Tour may have noticed a new, and yet-unreleased Sidi shoe beneath Green Jersey winner Peter Sagan as he stormed to each of his impressive three stage wins. Now available to assist with your own pursuit of the maillot vert, are the Sidi Wire Shoes -- the next footwear evolution from Sidi that improves on the fit of its predecessor while tipping the scales a full 60 grams lighter.
