Transiro Hydra is a triathlon shoe designed to facilitate easier transitions, built with a breathable upper and moderately stiff nylon outsole that combines comfort and pedalling efficiency.
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-shoe 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.
Easy-Breathing Air Mesh
The simple closure system is coupled with an upper made of 3D air-mesh fabric for a shoe that is highly breathable to help avoid overly sweaty feet, making this an optimal solution for those who prefer to race sockless.Â
Comfort, Efficiency, Control
The newly redesigned R5 nylon outsole offers comfort and a moderate level of stiffness for efficient pedalling. Additionally, cleat positioning is set slightly further back compared to traditional settings to better optimize pedalling efficiency and reduce knee compression. A wide vent inlet provides cooling airflow, aiding in temperature regulation.
