The Redline Classic delivers both performance and comfort with our super light carbon construction and our RaceWrap low-cut liner technology. The Integrated Carbon Base is sculpted to provide a performance fit for a wider range of feet. The carbon fiber layup is tuned for a spring-like classic flex in the forefoot, while providing the torsional rigidity and heel hold that only a carbon composite boot construction can deliver. Additionally, the Redline Classic boot features built-in MemoryFoam that conforms to the contours of the foot and delivers secure heel hold for even the most difficult-to-fit feet. The new RaceWrap low-cut liner construction provides a more contoured and comfortable fit through the arch and forefoot. Weighing only 320g/size 42, this boot will help you reach your goals in comfort.
