K2 Spyne 100 Ski Boots 2018

For an all-mountain connoisseur who prefers a flex that is stiff, but still versatile enough in varied snow conditions, the K2 Spyne 100 Ski Boots are just where you need them. With their LuxFitPro Liner and 100 mm last, the Spyne 100 will fit most average width feet superbly out of the box or with a bit of help from your bootfitter. The 100 flex provides enough support for faster, steeper skiing without being blocky and stiff on easier terrain.
