R4B Uomo: fi’zi:k’s range of road cycling shoes is developed in collaboration with leading professional cyclists and used to great effect by WorldTour, Olympic, and World Championship riders. The best technologies, materials, R&D, testing, and manufacturing techniques are used to deliver you the best shoes for road riding and racing and trickle down throughout the range.
R4B offers a carefully crafted blend of comfort and lightweight, fit, power transfer, and aerodynamic efficiency.
R4B’s single Boa IP1-A closure control is light, fast, secure, aerodynamic, and comfortable – and is complemented by a pair of light, neatly adjustable micro-straps.
The R4B’s injected carbon fiber outsole is stiff for power transfer and sculpted to aid aerodynamics. It combines with the proven supportive and comfortable fi’zi:k Cycling Insole with sculpted footbeds and supportive heel to ensure that every precious watt goes straight into your pedals.
The R4B’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.
