Who should not buy the Fizik Transiro Infinito R3

Cyclists looking for a shoe that offers total comfort might have to look past the Transiro Infinito R3. One reviewer lamented that the shoe's "boa dial is in a very uncomfortable spot, right on the pinky toe bone." Also, folks on a tight budget might have to look elsewhere because of the shoe's expensive price tag. Have a look at the Fizik Tempo Overcurve R4  instead, it might fit the bill.

Race-level stiff. This Fizik bike shoe employs the brand's R3 unidirectional full carbon outsole - the stiffest type of biking outsole. It yields optimal power transfer to prevent wastage of energy.

Breathable. The sole has wide ventilation pockets that enhance airflow and breathability than road bike shoes. It also acts as drainage port when transitioning from swimming to cycling.

Replaceable sole pads. Rubber heel pads can be replaced, and this allows the wearer to get the ultimate use out of this shoe. It helps in refreshing the grip once it starts to dull out.

Cleat System

The Fizik Transiro Infinito R3 uses the traditional three-bolt road cleat system. Some of the pedals that are suitable for this shoe are Shimano 105 SPD-SL Carbon, Look Keo 2 Max Carbon, and Time Xpresso 6.

Printed markings guide the precise cleat positioning.


Fast transitions. One of the critical parts of quick transitions in triathlon competitions is the shoe's closure system. The Transiro Infinito R3's retention system consists of a BOA IP1-B dial and a Powerstrap. The strap can be locked in the wide position read for quick foot entry.

A heel loop allows effortless on and off. Once the foot is in, the strap is tightened and it secures the foot inside quickly. Then the BOA dial offers tuneable fit adjustments even while on the go.

Airflow and support. The Fizik Trnasiro Infinito R3 is crafted with a mesh upper with laminated PU in targeted areas. The mesh upper allows excellent breathability while the PU keeps the foot in place and works in conjunction with the stiff soles for efficient power transfer.
