Fizik Transiro R3 Infinito Shoe 47 Black/WhiteFizik Transiro R3 Infinito Shoe is a triathlon shoe that combines a stiff outsole with quick entry and fine tune ability. The mesh upper is highly breathable and the PU laminated targeted areas provide assurances power will be transferred efficiently to the pedal. Athletes come in all shapes and sizes so Fizik designed this shoe with Volume Control giving you the flexibility to slide right in with the Powerstrap while fine tuning for an ideal fit with the Boa dial. The volume is also controlled by Infinito, a signature fit adjustment feature. It eliminates pressure spots and balances tension by using textile webbing instead of plastic lace guides. The stiff R3 full carbon unidirectional outsole combines power transfer with exceptional breathability. Weighs 476g and is available in Black/White.F8485470
