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.

Fizik is an Italian premium cycling brand focused on the contact points between rider and bike — saddles, cycling shoes, handlebar tapes and other components that directly influence comfort, control and performance.
Part of the Selle Royal Group, the brand combines Italian design, biomechanics and experience from competitive cycling. While Selle Royal has historically been known for comfortable saddles for urban, trekking and recreational riding, Fizik was created for a more performance-oriented direction — for riders who expect every contact point on the bike to work precisely, efficiently and with minimal weight.
Fizik’s saddle range is built around different riding positions, rider mobility and disciplines. Well-known saddle families such as Arione, Antares, Aliante and Argo offer different shapes, from long and flat racing saddles to shorter-nose models designed to help reduce pressure in sensitive areas. The range includes options for road cycling, gravel, mountain biking and triathlon.
One of the brand’s most advanced technologies is the Adaptive series — saddles with 3D-printed padding, where the zonal structure is designed to provide support and comfort exactly where the rider needs it. This makes it possible to combine race-level stiffness, low weight and improved pressure distribution in a way that is difficult to achieve with traditional foam padding.
In addition to saddles, Fizik produces high-end cycling shoes for road, gravel and mountain biking. The focus is on stiffness, fit, power transfer and ventilation — qualities that matter both to racers and demanding enthusiasts. Handlebar tapes and other accessories complete the range, giving the rider a consistent feel across all key contact points.
Fizik’s philosophy is simple: the best ride starts where the rider meets the bike. Saddles, shoes and handlebars are not just accessories — they determine whether a ride feels fast, comfortable and controlled, or becomes harder with every kilometre.
