Equipped with a soft instep closure system, it is a strap positioned on the instep, shaped, soft, and anatomical, paired with soft material for greater comfort. It distributes pressure evenly on the instep and adjusts on both sides to have a perfectly centered strap position depending on whether the instep is low or high. The system eliminates the need to use a spacer. Very lightweight shoe (320 g US 8.8).

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 with a new type of cable that allows quick adjustment with great ease. Like most mechanisms used by Sidi, the TECNO-3 lever is sturdy and replaceable.

Integrated Sidi heel
The heel is integrated, newly designed, lightweight, and reinforced to prevent deformation after prolonged stress and pressure. Anatomically shaped, it stabilizes and supports the foot during pedaling. REFLEX inserts on the heel provide greater safety for the athlete on the road, helping to signal the cyclist's presence in low visibility conditions.

Non-slip heel
Sidi cycling shoes feature a replaceable polyurethane heel.

Carbon composite 20 sole
The carbon composite 20 sole is made of injected nylon and carbon fiber. Nylon helps maintain the technical features unchanged over time. The result is a lightweight and stiff sole. The central part of the sole is graduated, with a millimeter scale, to facilitate the correct attachment of cleats. Equipped with a replaceable polyurethane heel.
