Fizik Knit uppers are a cut above traditional woven fabric or microfiber uppers. These uppers are created with electronic knitting machines by linking loops of yarn on needles and they are able to seamlessly change the yarn direction of the fabric to create different stitching patterns. This means being able to design and create functional zones, with engineered performance in key areas, such as vents and mesh openings for enhanced breathability. The added water-repellency treatment shrugs off rain and road spray. To guarantee efficient power transfer to the pedals, targeted areas of heat-fused PU have been integrated to create foot support where athletes need it most. This construction ensures the shoe has superior ventilation and is ultra-lightweight, but with the same support and pedalling efficiency as a traditionally built cycling shoe.
The Volume Control system allows a differentiated fit adjustment for the instep and forefoot areas – the shape and volume of which can vary widely between riders. By controlling two separate Boa closures, cyclists 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.
A customized fit of the plantar arch is provided with the Dynamic Arch Support, a dedicated piece of the shoe’s upper that wraps around the plantar arch, and is adjusted for fit with its own Boa dial.
The R1 highly stiff uni-directional full carbon outsole is tuned for the maximum power transfer with vent openings channelling the airflow through the sole for an efficient temperature control
