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 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 pedaling efficiency as a traditionally built cycling shoe.
