The pursuit of reducing weight and increasing ventilation, while maintaining support and protection led our designers and engineers to the development of a new material used in the upper. Called aeroweave, its an advanced woven fabric that interlaces lightweight nylon fibers with filaments of thermoplastic polymer. This blend of threads creates a material with an open, net-like pattern that is extremely airy, yet highly resistant and resilient. The vento powerstrap r2 aeroweaves upper is so intensely vented that the riders socks are visible through it. Aeroweave is a malleable material, and moves to effectively cradle the foot, but its tenacity delivers the support and containment required for a high performance racing shoe.
The aeroweave upper is complemented by powerstrap, fiziks innovative velcro closure designed for an enveloping fit. While most traditional velcro closures just pull together two sides of the shoes upper, in the vento powerstrap configuration a ribbon wraps around the foot, providing secure containment using just two straps. The instep and the midfoot are separately adjustable for customized fit and compression. These straps have been streamlined to make them even lighter and stronger.
Vento powerstrap r2 aeroweave also features a whole new outsole: the r2 outsoles engineered carbon fiber layup saves weight and delivers increased stiffness. With an index of 10, the r2 is the stiffest outsole in the fizik range. A wide vent inlet and deep internal channelling provide a cooling airflow, contributing to temperature management. The cleat positioning is slightly further rear-wards compared to traditional settings, to optimize pedalling efficiency and reduce knee compression, especially well suited to very aggressive, forward aero positions.
