The Redline Classic – performance and comfort with super lightweight construction. The Integrated Carbon Base has been sculpted to provide 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 construction can deliver. The Redline Classic boot features a heel with built-in memory foam to conform and hold even the most difficult-to-fit feet. Weighing only 320g/size 42 this boot will help you reach your goals in comfort. The brand new RaceWrap low-cut liner construction provides a more contoured and comfortable fit.
