Hydra is a triathlon bike shoe designed to facilitate easier transitions, built with a breathable upper and moderately stiff nylon outsole that combines comfort and pedaling efficiency.
TRANSITION QUICKLY
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. 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.
EASY-BREATHING AIR MESH
The simple closure system is coupled with an upper made of 3D air-mesh fabric for a shoe that’s highly breathable to help avoid overly sweaty feet, making this an optimal solution for those who prefer to race sockless.
COMFORT, EFFICIENCY, CONTROL
The newly redesigned R5 nylon outsole offers comfort and a moderate level of stiffness for efficient pedaling. Additionally, cleat positioning is set slightly further back compared to traditional settings to better optimize pedaling efficiency and reduce knee compression. A wide vent inlet provides cooling airflow, aiding in temperature regulation.
