With an upgraded sole that's stiffer and lighter than SIDI's all-conquering Carbon Lite Sole, the SIDI Genius 6.6 Vent Carbon Mega Road Shoes offer competition-proven efficiency, power transfer and all-day comfort for high-performance, high-mileage cyclists. New Vent Carbon Sole with integrated vents and air channels provide heat dissipation, improved comfort, and water drainage, plus they can be opened and closed for 4-season comfort. This sole is also ultra-light, super stiff and its medium-modulus carbon construction provides incredible drive. Adjustable Heel Security System eliminates heel lift, SIDI Heel cup boosts power transfer, and High Security Velcro straps with Caliper Buckle 2-way ratchet give a precise, secure fit.
