The CSK was designed completel around the Xcelerator sole. Featuring an asymmetric carbon cuff, carbon stabilizer, Thinsulate insulation, and a one-piece 4Dry upper that provides water resistance and breathability, this boot delivers performance and comfort. An ideal boot for those seeking the performance of a carbon boot but at a more approachable price point than the ESK Pro.

In our experience this boot runs about one size larger than the ESK and most other Alpina boots.
