Fizik TRANSIRO HYDRA AEROWEAVE CARBON Triathlon Shoes
Hydra Aeroweave Carbon is a lightweight, ultra-breathable pure triathlon racing shoe that combines an innovative second-generation Aeroweave upper with a stiff carbon outsole for efficient pedaling and faster, worry-free transitions.
- Aeroweave upper: an enveloping and extremely breathable net-like upper structure
- R2 outsole: full carbon unidirectional, Stiffness index 10
- Weight: 225g
- Sizes: 36-48 (37 to 47 also in half sizes)
FASTER TRI TRANSITIONS
As transitions become increasingly important—now considered the fourth discipline in any triathlon event, be that a full Ironman race or sprint distance—we have redesigned our tri-shoes range to meet the requirements of the most demanding athletes. Transiro Hydra is built with a single Velcro strap to allow faster, worry-free transitions, where any mistake can cost decisive time. Additionally, the enveloping strap provides the strong foot support athletes need to be efficient in every race situation.
SOFTER, BREATHABLE SUPPORT
The Aeroweave upper ensures maximum breathability. Now in its second generation, Aeroweave woven fabric interlaces nylon fibers with filaments of thermoplastic polymers for an even lighter shoe that doesn’t lose its original tenacity, providing the strength and support required in competition. The new upper is also softer, which makes it the perfect companion for those who prefer to approach the biking segment sockless.
POWERING PEDALS
At the base, the R2 outsole’s engineered carbon-fiber layup saves weight and delivers increased stiffness, with a stiffness index rating of 10, making this outsole the most responsive in the fizik range. A wide vent inlet and deep internal channeling provide cooling airflow to aid in temperature regulation. The cleat positioning is set slightly further back compared to traditional settings to optimize pedaling efficiency and reduce knee compression—especially well-suited for very aggressive, forward aero positions typically adopted by triathletes.

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.
