Fizik Vento Infinito Carbon 2 Road ShoesDeveloped, tested and refined with professional cyclists, the Fizik Vento Infinito Carbon 2 Road Shoes give you unrivalled levels of comfort and pedalling efficiency. Stamp on the pedals and enjoy the instantaneous response. Supple and StrongWith an upper made from Microtex, the Vento Infinito Carbon 2 Road Shoes give you a fit that is both supple and strong, providing comfort from the very first pedal stroke. It also gives a precise and supportive fit of the foot, ensuring a stable platform during the whole of your crank rotation, driving pedalling efficiency.Customised Fit - BOA Fit SystemTo give a customisable and comfortable fit, the Vento uses the dual Li2 BOA fit system. The Li2 dials have been redesigned to offer a lower profile, marginally improving aerodynamics while also making them less vulnerable to being accidentally hit. Each dial gives quick and easy micro-adjustment, with independent adjustment of the forefoot and instep. Fine-tuning the fit to your particular foot shape is now remarkably easy. R2 Carbon OutsoleThe stiffest and lightest sole unit in the Fizik range, R2 Carbon Outsole delivers incredible responsiveness, with power transferred to your pedals with outstanding efficiency. Jump for a sprint or attack a climb and you're rewarded with immediate acceleration - only fitness is holding you back.Efficient pedalling is also optimised thanks to the cleat track position. This has been set further rearwards to improve pedalling dynamics, reduce knee compression and power transfer - it's especially well-suited to very aggressive, forward aero riding positions.Cleat GuidanceThese Cycling Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact.Features:Knitted PU laminated mesh upperLi2 Dual Zone BOA Fit SystemIndependent fit adjustment for instep and forefootDynamic Arch Support 2.0: tailored fit of the plantar archR2 carbon outsole - full carbon unidirectional, stiffness index 10/103-bolt cleat compatible (cleats not supplied)Weight: 225g (size 42 - 1/2 pair)Buy Fizik Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.
