Sidi doesn't compromise on materials, construction or finish. The Sidi women's Zephyr Carbon Cycling shoe with the Millennium 3 Carbon Composite Sole is more durable and mechanically stable than just a typical road cycling shoe. The injected carbon fiber provides more rigidity than a standard nylon sole and it's less susceptible to changes in stiffness resulting from prolonged usage and changes in temperature. So ride Sally ride.
An anti-slip toe insert and replaceable polyurethane heel pad are incorporated into the Millennium 3 Carbon Composite Sole, for walkability.
The Millennium 3 Carbon Composite Sole is compatible with the best pedal systems available, and includes a printed 10mm lateral and fore-aft cleat alignment scale on the sole as well as the Look Memory Eyelet for easy cleat alignment and replacement.
