A classic road shoe, the Energy 2 Carbon Composite isused by many professionals by choice and comes together to offer the rider the superior quality and comfort that is Sidi.

The Carbon Composit Sole is thinner in the toe to provide a slight amount of flex while retaining exxcellent stiffness and power transfer in the body of the shoe. The sole is engineered for the high performace, high mileage cyclist who requires a sole that is rigid but does not compromise the foot's blood circulation, guaranteeing comfort and great performance. The Carbon Composite Sole is made out of injected Carbon Fibre in a matrix of Nylon. The Nylon used is preferable to standard Nylon because it does not absorb water and does'nt lose rigidity in hot or humid weather or as it ages.

SL Buckle: Allows locking in two different ways; by taking up a number of clicks with one sweep of the lever, Or engaging one half a click at a time for a ruly micrometric adjustment.  The two red flaps may be pressed together for complete unlocking or alternatively to slightly loosen the shoe during performance.

Soft Instep Closure System: The rigid polyurethane part has been reduced and coupled to soft, thermo-formed Eva and it is anatomical. The system eliminates the need for the High Instep Extender. Increased comfort and performance.
