Fizik Men's Vento Powerstrap Aeroweave Lightweight, Ultra-Breathable Road Cycling Shoes, White, 12.5
Origin: ImportedSole material: NylonOuter material: Thermoplastic Polyurethane (TPU)Closure type: PowerstrapAEROWEAVE: The pursuit of reducing weight and increasing ventilation while maintaining support and protection led our designers and engineers to develop an entirely new material: Aeroweave. Now in its second generation, Aeroweave woven fabric interlaces nylon fibers with filaments of thermoplastic polymers for an even lighter shoe that doesn’t lose its original tenacity, providing the strength and support required in competition.POWERSTRAP: While most traditional Velcro closures simply pull together both sides of the shoe’s 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, and now, these straps have been streamlined to make them even lighter and stronger.R3 OUTSOLE: Vento Powerstrap Aeroweave also features an entirely new outsole, the R3, engineered with an updated carbon fiber layup and new design to save weight without compromising stiffness. With an index of 10, the R3 is a stiff outsole providing optimal power transfer. Two wide vent inlets and deep internal channelling enable a cooling airflow, contributing to temperature management.
