From R3 to R4, latest Transiro Powerstrap R4 tri shoe from fizik


Hot-on-the-heels of unveiling Transiro Infinito R3, accessories specialist fizik has stepped out with its new Transiro Powerstrap R4 shoe. According to the Italian company, this latest shoe is ‘an important model in fizik’s new Transiro triathlon series of shoes and saddles – a series that has been created for uncompromised cycling performance in multisport competition, and the most efficient transitions possible.’

The fast-entry Transiro Powerstrap R4 shoe is designed with features optimally suited to sprint or short distance triathlon formats. Transiro Powerstrap R4 also features the new Powerstrap closure system: an enveloping Velcro closure.

fizik notes that Powerstrap is super-quick to fasten. The twin Velcro straps are designed to pull an extended area of the shoe’s upper, so the fit is enveloping and secure, even with a relatively simple system.

To ease transition, the Powerstrap can be locked in the wide open position ready for quick and easy foot entry. The heel has a rubberized loop for setting the shoes ready-clipped into the pedals.

Transiro Powerstrap R4’s upper is constructed combining mesh with Microtex, to ensure appropriate foot support. The upper is complemented by a moderately stiff R4 carbon injected nylon outsole.
