Upper in Technomicro Microfibre

Technomicro is a composite microfiber material created from strands that are so fine, each one is less than one thousand  the thickness of silk. These fibers act like natural leather skin, but with the advantage of better strength, softer texture and lighter weight. Technomicro is also water resistant, highly resistant to abrasion and tearing and is easy to clean and maintain. Technomicro doesn’t stain and offers reduced weight, more flexibility and a better feel than leather or other synthetic material boots

Lined with Maglina Air teflon

Tecno-3 steel closure system, no need for zips

The innovative CLOSURE SYSTEM allows a simply and quick fit. The boot is equipped with 3 steel cables adjustable closures with TECNO-3 PUSH rotor. The PUSH button allows the buckle to be lifted for more closing pressure. The shin and ankle mechanisms allow a symmetric closure. The instep mechanism ensures a snug yet comfortable fit.

External glass fiber ankle support

A single ANKLE SUPPORT BRACE joins the internal and external ankle joint for more support. In the outer lower part, the ankle support brace is equipped with air vents which can be operated by an aerodynamic shaped button. The ankle support brace is made with NYLON material with GLASS FIBER. Small slots on the joint’s central part allows perspiration and air dissipation

Padded upper lining

Along the entire boot, on the inside part of the bootleg, there’s a padded upper lined with air jersey and Cambrelle. The upper ends with a sturdy pull tab for easy fitting.

Elastic panels on front and back joints

The ELASTIC PANELS placed on the front and back joints are internally padded and widens while the foot passes for a comfortable and easy fitting.

Asymmetric heel cup

ASYMMETRIC and shaped HEEL CUP equipped with a soft fixed insert on the internal side of the ankle for better adherence and contact with the bike.

Replacable shin plate

Vortice toe sliders


The toe slider is made in nylon reinforced with fiberglass. It is fitted with an intake and an innovative alloy insert.
