Sizing and Fit
I'm usually a size 47 in Shimano and Giro shoes, but these Fizik R1 Infinito felt slightly larger, particularly in the toe box. This was unexpected, as I consider my foot size average. The fit is comfortable, with the upper volume control system providing a snug feel throughout the foot. It takes some getting used to, but overall it's a nice fit.
Construction and Materials
The shoes boast a stiff, unidirectional carbon sole. The Boa closure system is efficient and easy to use. However, some aspects of the finish feel a bit unfinished, especially near the edges where the micro-tex material appears thin. This raises some concerns about the long-term durability of those areas.
Performance on the Bike
The stiffness of the sole is excellent, resulting in efficient power transfer. Climbing hills felt incredibly smooth and powerful. The superior power transfer was impressive, especially for my first experience with carbon-soled shoes.
Weaknesses and Issues
The lack of grip is a significant drawback. The sole, especially the front pads, offers very little traction, making walking around problematic. This is further compounded by the fact that my cleats are rubbing against the shoe. I also experienced some foot rolling due to a taper on the shoe, causing rubbing and damage to the sole. This could be exacerbated by my choice of pedals and cleats.
Overall Conclusion
The Fizik R1 Infinito shoes offer excellent power transfer and a comfortable fit (once adjusted to the larger sizing). However, the significant lack of grip and the issue with cleat rubbing significantly detract from the overall experience. While they excel on the bike, their impracticality for walking makes them unsuitable for many cyclists. The high retail price is another consideration. Unless you prioritize pure performance above all else and rarely dismount your bike, there are likely better options available.
