Worn by a number of pro riders from Vincenzo Nibali to Chris Froome. The Italian shoe brand have become synonymous with quality and high performance. The Sidi Alba features the Millennium 4 Carbon Sole, constructed from injected carbon fiber in a matrix of Nylon thus providing more rigidity than a standard nylon sole. Sidi\\\'s Techno-3 System dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit. The soft instep closure system is a wide anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area and a reinforced cup stabilizes and supports the heel.
