Transsiro Infinito R3 is a triathlon shoe that combines a rigid sole with a quick entry to the feet and a finely adjustable fit on the move. The mesh upper is highly breathable but effectively supportive, thanks to PU lamination on targeted areas that ensure that all power is transferred efficiently to the pedals. The volume control system allows differentiated adjustment for instep and forefoot areas, whose shape and volume can vary greatly among athletes. The combination of a Powerstrap and Boa® dial is the ideal balance for an Olympic format: first a quick and secure closure, then an adjustable fine adjustment for a precise fit.

• PU laminated mesh upper: enhanced ventilation with support where needed
• R3 full UD carbon outsole: highly stiff interface ideal for a direct power transfer
• Instep Powerstrap: intuitive, quick and secure closure
• Infinito: advanced volume control of the forefoot area
