The Redline Classic boot has been upgraded in 2019 with a focus on improving performance and comfort. The Integrated Carbon Base has been adjusted 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 torsional rigidity and heel hold like only a carbon composite can. The Redline Classic features the Memory Heel with thick memory foam to conform and hold even the most difficult-to-fit feet. Weighing in at only 330g, this boot will help you tackle even the most ambitious goals in comfort.
