SkiTourers and FreeTourers who demand top performance in all conditions, and want to stand out from the crowd. This is our new Flagship Ski Touring boot. This the first 4 buckle ski boot with a full carbon fiber cuff, for dramatic downhill performance and weight reduction. The new cuff also offers a wider rotation compared to the traditional ZZero cuff and a newly designed ski/walk mechanism that perfectly matches the new carbon fiber back-bone. This is clearly the best performing touring boot in its weight range.
