Having a proper fitting, comfortable ski boot is at the top of every skiers priority list. The K2 B.F.C. 90 fits like a slipper right out of the box thanks to its 103mm last and the easiest foot entry/exit in the game. We included our Powerfuse Spyne technology—a feature found on our high-end boots—on the B.F.C. 90 to strengthen and add lateral support to the shell for maximum responsiveness, yet the boot remains a true 90 flex for finessing turns on every run from groomers to bumps and powder. Our cuff alignment feature allows you to add custom cant to the upper cuff of the boot, and lastly fully replaceable/upgradeable outsoles for added grip and increased lifespan of the boot. The tech packed B.F.C. 90 gives you all the features you need to ski from bell to bell without sacrificing comfort or fit.
