Fizik’s Transiro R1 Infinito Knit Triathlon Shoe is engineered for optimal performance and seamless transition. The knitted upper yields distinct functional zones with engineered performance such as vents and mesh openings for enhanced breathability. The water-repellent treatment prevents the yarn from absorbing moisture. The combination of enhanced breathability and water-resistance results in an upper that dries quickly when slipping on with wet feet after T1.
Targeted areas of heat-fused PU have been integrated to create foot support where it's most needed. This construction ensures the shoe has superior ventilation and is ultra-lightweight, but with the same support and pedaling efficiency as a traditionally built cycling shoe.
The Boa-powered Volume Control zonal fit is quick, intuitive, and provides the locked-in feel triathletes need for a 112-mile ride. The Volume Control system allows a differentiated fit adjustment for the instep and forefoot areas. By controlling two separate Boa dial closures, triathletes can fine-tune shoe fit to their unique foot shape for customized comfort and support.
The volume of the forefoot area can be controlled via the Infinito, a signature fit adjustment feature. Infinito balances out the tensioning and further eliminates pressure hot spots by using textile webbing in place of plastic lace guides. This closure system acts on a larger area of the shoe’s upper, pulling the eyestays inwards consistently from all directions for a more supportive and comfortable fit.
