The Sidi Alba are perfect shoes for training, touring, and even competitions. The Politex upper offers abrasion resistance and protection, while comfort is ensured by the closure system with double velcro and Tecno 3 System micrometric ratchet.

• Politex Material: Politex material consists of multiple overlapping layers with different physical-mechanical properties, combined with 2 fabrics (mesh + felt) that provide particular resistance to tearing and ripping. The material is made in strict compliance with European regulations.
• Tecno – 3 System: The TECNO-3 mechanism allows the shoe to be closed along its entire length, adapting the upper to the shape of the foot and thus achieving a customized fit. The reliable SIDI closure systems, fully replaceable, have been improved thanks to a new type of cable that allows quick adjustment with extreme ease. Like most mechanisms used by Sidi, the TECNO-3 lever is sturdy and replaceable.
• Sidi Heel: The heel is reinforced to prevent deformation after prolonged stress and pressure.
• Replaceable Heel: Sidi cycling shoes feature a replaceable polyurethane heel pad on the heel.
• Millennium 4 Carbon Composite Sole: The MILLENNIUM 4 CARBON COMPOSITE SOLE is made of nylon injected with carbon fiber, providing greater stiffness compared to a standard nylon sole. MILLENNIUM 4 CARBON COMPOSITE is durable, water-resistant, and mechanically stable, meaning it is less prone to stiffness variations caused by prolonged use, aging, and changes in temperature or humidity. It features a replaceable non-slip insert on the heel to facilitate walking. MILLENNIUM 4 CARBON COMPOSITE is compatible with the best pedal systems and includes a lateral and longitudinal alignment scale printed on the sole for cleat positioning, plus the ability to memorize the Look cleat position.
