FIZIK R4B UOMO MEN black/white

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 Fizik 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.
