The Sidi Genius 6.6 Speedplay Carbon shoe is Sidi's Tour de France and Giro d Italia winning road shoe made specifically to fit the 4-hole SpeedPlay cleat. This SpeedPlay specific model delivers three primary benefits for SpeedPlay pedal users. First, there is no need to use the three-hole adapter included with SpeedPlay cleats which saves 62 grams of weight. Cleat mounting is more direct with 4mm of reduced stack height for more efficient pedaling and power transfer. The sole of the Ergo 3 SP Carbon also allows 6mm of additional aft adjustment along with a simplified cleat set up.
Full carbon sole is made from aerospace-quality carbon
Rigid for excellent power transfer but has some toe flex engineered for enhanced comfort
Instep closure system for a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area
