The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.
The Twelve Carbon Composite Sole is made of carbon-reinforced nylon with a carbon insert for optimum power transmission and flexibility in the forefoot – the ideal combination of comfort and rigidity. It uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and features an alignment scale for correct positioning of the cleats and a replaceable polyurethane heel pad for walkability.
Please note: Sidi shoes are quite small. We strongly recommend to take one size larger than usual.
