Transiro R4 Powerstrap

A comfortable triathlon cycling shoe with a fast and intuitive Velcro Powerstrap closure system, a mesh and microtex upper for superior ventilation, and an R4 carbon outsole for efficient power transfer.

The upper is complemented by a moderately stiff R4 outsole, delivering a striking balance between comfort and pedalling efficiency while still providing efficient ventilation for temperature control.

Powerstrap is extremely quick to fasten: simply slide into the shoe, pull and roll out from the transition smoothly. The strap is designed to pull an extended area of the shoe’s upper, so the fit is enveloping and secure, even with a relatively simple system.
