Fi'zi:k Transiro R4 Powerstrap Shoe


Transiro R4 Powerstrap Shoe

For sprint or short distance triathlons, every second you shave from your transition matters, and can help give you that extra edge over the competition. To speed up your transitions, take a look at the Fi'zi:k Transiro R4 Powerstrap Shoe with its quick and intuitive closure system. The Powerstrap is extremely quick to fasten, and is designed to pull an extended area of the shoe's upper, leading to a secure and enveloping fit despite the relatively simple system.

To ease transitions even further, the shoe can be locked in the wide open position for easy foot entry. A rubberized loop on the heel facilitates setting the shoes while clipped into the pedals, and makes it easy to quickly pull your feet into them as you're rolling out of the transition.

The Transiro R4 is constructed from a blend of Microtex and mesh, ensuring proper foot support and superior ventilation with every pedal stroke. The upper is complemented by a moderately stiff R4 carbon-injected outsole, striking a good balance between comfort and pedaling efficiency while providing additional ventilation through the bottom of the shoe.

Loved this shoe and it was a perfect fit. However, it could not accommodate an spd clip so I had to return it. So bummed because it is such a unique shoe.
