Fizik's latest Infinito has further refined the riding position and reduced weight of this peloton favorite for elite road racing. Infinito construction provides better forefoot fit ensuring even tension and fit across the top of the foot. Second Boa dial on the arch fits snugly to the foot providing better leg support when running in a straight line. For optimal power transfer, Fizik's stiffest carbon fiber outsole is used, with the cleats set back slightly for greater efficiency from foot to pedal. Fizik knows that performance is only part of the equation Therefore, breathable Microtex ventilation channels in the upper and midsole help regulate temperature passing air through shoes so you can focus on catching and passing the push.
