Hydra Aeroweave carbon is a 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.
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.
SPECIFICATIONS
- 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)
FEEDBACK
I found the stretchy fabric to be a poor substitute for a lower closure. It's less customizable and was not suitable for high arches as it created a pressure point across the top of the foot. The white woven material also looks great now, but I could just imagine it getting filthy and gross. These were returned.

Great fit. I enjoy the ease of being able to get the shoe on and feet in and out. The straps do not get in the way. Very breathable. Comfortable and have had no issues wearing without socks

I dove only 80 km - two rides - and one shoe was broken - the glue has come off - bad quality

Like it. But, the friction pads at back of heel irritates my skin and seem unnecessary.

These are some of the most comfortable shoes that I've ever biked in. Even 5-6 hours later when my feet start to swell, I haven't had any discomfort with these shoes. I highly, highly recommend them! These shoes breathe really, really well!! They don't hold sweat or rain, and the cleats have more adjustability than the other Fizik R4s. They are stiff as well! Great for racing or training rides!
I have wide and flat feet and these fit me great. The R1 and R3 are too narrow for me but these are perfect! I'll be buying these again in the future!
