Fizik R3 Transiro

The Tansiro Infinito R3 is a triathlon shoe by Fi'zi:k that offers a stiff outsole and a quick foot entry. Its fine tuneable fit allows for adjustments on the go. The mesh upper is highly breathable and supportive, thanks to the PU lamination in targeted areas that efficiently transfers power to the pedals. The Volume Control system allows for a differentiated fit adjustment for the instep and forefoot areas, which can vary widely between athletes.This shoe features a combination of a Powerstrap and a BOA dial, offering a quick and secure closure, as well as a precise fit. The volume of the forefoot area can be controlled via the signature fit adjustment feature called the Infinito. This system eliminates pressure hot spots by using textile webbing instead of plastic lace guides, providing a more supportive and comfortable fit.The R3 unidirectional carbon outsole delivers ultimate power transfer and boasts wide ventilation cutouts, providing even greater breathability than its road counterpart. Transitioning is made easier with the instep Powerstrap, which can be locked in the wide open position for quick and easy foot entry. The shoe also features a rubberised loop on the heel to facilitate setting the shoes ready clipped into the pedals.Specifications:- Upper: PU laminated mesh- Outsole: R3 full uni-directional carbon fibre- Closure system: instep Powerstrap and volume control infinito BOA IP1-B- Approximate weight: 476g (size 42)
