The new Redline Skate boot is engineered to provide even more stability, power and control. Weighing in at 445 grams (size 42), the new Redline Skate boot comes with a stiffer, interchangeable Power Cuff, and a totally redesigned Redline Integrated Carbon Base to improve stability around the heel as well as greatly improving the overall fit through the arch and forefoot. The new RaceWrap low-cut liner construction provides a more contoured, more comfortable fit so you have maximum control over your skis.
