Triathlon Shoes Fizik TRANSIRO INFINITO R3

The Fizik TRANSIRO INFINITO R3 triathlon shoes are designed for athletes who demand maximum power transfer, efficient transitions and a precisely adjustable fit. The TRANSIRO series focuses on uncompromised cycling performance while helping make the transition from swim to bike and bike to run as smooth and efficient as possible.

The upper is made from PU-laminated mesh, combining high ventilation with targeted support. Reinforced areas provide stability where it is needed most and help transfer power efficiently to the pedals, while the open mesh construction keeps the feet cooler during demanding races and hot-weather training.

The closure system combines a fast Instep Powerstrap with a BOA IP1-B dial. The wide strap allows the shoe to be closed quickly and securely in the transition area, while the BOA dial provides precise on-the-bike adjustment. This combination is particularly well suited to Olympic-distance triathlon, where rapid entry and fine-tuning during the ride are equally important.

The Volume Control system allows independent fit adjustment across the instep and forefoot, accommodating the wide variation in foot shape and volume between athletes. The Infinito system distributes tension more evenly across the upper and uses textile webbing instead of rigid plastic lace guides. This helps reduce pressure hotspots while creating a more supportive and comfortable fit.

The race-stiff R3 outsole is made from full unidirectional carbon and provides a highly rigid interface for direct power transfer. Extra-wide ventilation cutouts improve airflow and make the sole even more breathable than its road-specific counterpart. The shoe is engineered for paved-road performance, from smooth tarmac to demanding pavé.
