R4B offers a carefully crafted blend of comfort and light weight, 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.
R4B Uomo weighs just 254g (size 42.5).

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 manufacture techniques are used to deliver you the best shoes for road riding and racing, and trickle down throughout the range.
The Microtex upper is supple yet strong and stable for a comfortable and consistent fit. It is assembled in a sleek and streamlined yet highly ergonomic pattern, offering you the protection you need.
Overcurve is a shoe construction featuring a staggered collar that wraps around the ankle, tracing the natural misalignment of the ankle’s two bony protrusions: the lateral and medial malleoli. The result is an asymmetrical shape, with the throat of the shoe curving over the foot from its outside to its inner side. The closure is simple and secure, powered by a micro-adjustable BOA IP1 dial.
Vento Overcurve X3 are assembled with extensive use of welding and laminated reinforcements, reducing exposed stitching that could collect dirt. They are light but tough, durable and easy to wipe and clean.
The race-orientated characteristics of these shoes are continued with the X3 carbon injected outsole: it’s minimal to save weight, but stiff for power transfer, and with an aggressive tread that claws the ground and easily sheds the mud.
