Sidi Alba 2

Soft Instep Cloud System 3
The Soft Instep Closure System is a wide, anatomically curved strap combined with a soft, thermoformed EVA cushion that distributes pressure evenly over the instep area. The Soft Instep Closure System is adjustable on both sides to perfectly center the EVA cushion on a high or low instep. The system eliminates the need for a high instep expander and is replaceable.

Techno-3 System
The Techno-3 System at Sidi consists of dials that adjust along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit. The Sidi closures, known to be reliable and replaceable, are enhanced with an all-new proprietary material, Sidi Wire, which is completely non-binding for intuitive, effortless adjustments on the fly. Like most small parts from Sidi, the Techno-3 system is repairable and replaceable.

Head Cutter Sidi
Reinforced cup stabilizes and supports the heel. Anatomically shaped plastic reduces heel slip and provides increased power transfer, offering additional foot protection in the event of an accident.

Replaceable Heel Cup
For ease of walking, Sidi cycling shoes feature a replaceable polyurethane heel cup.

Millennium 4 Carbon Sole
The Millennium 4 Carbon Composite sole is made of carbon fibers injected into a nylon matrix, which gives it greater rigidity than a standard nylon sole. The Millennium 4 Carbon Composite outsole is also more durable, does not absorb water, and is mechanically stable, meaning it is less susceptible to changes in stiffness due to aging, prolonged use, and changes in temperature or humidity. The Millennium 4 Carbon Composite sole uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available and includes a 10mm printed scale for lateral and front/rear cleat alignment on the sole, as well as the Look Memory eyelet for easy cleat alignment and replacement.
