The R5B offers a carefully crafted blend of comfort and light weight, fit, power transfer and aerodynamic efficiency. R5B’s single Boa IP1-A closure control is light, fast, secure, aerodynamic and comfortable – and is complemented by one sail cloth strap. The R5B’s carbon reinforced Nylon outsole is stiff for power transfer and sculpted to aid aerodynamics. It combines with the proven supportive and comfortable Fizik Cycling Insole with sculpted foot-beds and supportive heel to ensure that every precious watt goes straight into your pedals. The R5B’s Microfiber upper is hard-wearing, light, and resilient with enough flexibility to ensure comfort for every rider’s foot, but strong enough to withstand the demands of racing – without any weight penalty. The diamond-shaped laser-cut perforations help temperature management and the reflective heel cap offers visibility on the road. R5B Uomo weighs just 250g.
