Who should buy the Fizik R4B

The Fizik R4B is one of the many road cycling shoes offered by the brand. The shoe is developed with the help of leading professional cyclists. It is a solid option if you:

  • Need a shoe that is carefully designed to offer the perfect blend of power transfer, comfort, lightweight fit, and aerodynamic efficiency. 
  • Need a shoe that injected carbon fiber outsole in combination with the signature Fizik cycling insole ensures that power transfer is maximal.

Excellent stiffness

This shoe’s outsole is crafted from the injected carbon material. It is stiff for excellent power transfer to the bike yet flexible enough for short walks.

Efficient aerodynamics of the R4B

It features curves designed for efficient aerodynamics while riding. It is aimed to help minimize air resistance and avoid what cyclists call “aerodynamic drag.”

Three-bolt cleat design

The R4B features a three-bolt cleat design. It is directly compatible with all SPD-SL pedal models and Speedplay style cleat engagement pedals. Check out the following pedal models to try: Shimano 105 SPD-SL, Look Keo Classic 3, Speedplay Zero Stainless, and Time Xpresso 15.

Durable and lightweight

Crafted from the Microtex material, the R4B is lighter and more durable than leather. The shoe is hard-wearing enough to withstand the demands of racing without adding any unnecessary weight. It also allows ample flexibility to ensure the rider’s comfort.


Equipped with diamond-shaped laser-cut perforations, the R4B manages temperature very well. It helps ensure your foot will stay cool.

Fizik R4B has an excellent fit

The R4B employs the combination of BOA IP1-A dials and micro-straps to provide an excellent fit. The micro-straps secure the upper part of the foot while the BOA closure supports the midfoot up to the upper part. This ultimately provides a smooth, even fit without any pressure points.

Tri-model function

Once the wearer figures out the comfortable position of the micro-straps, it doesn’t need to be re-adjusted again. Meanwhile, the BOA dial has a tri-model function: tighten, loosen, and complete release. These three functions could be done with one hand. Hence, adjustment while on the bike is made easy, and the full release function allows quick on and off.
