K2 B.F.C 75 W Gripwalk - Women's Ski Boots 2026

Ever wondered what BFC stands for? Probably not, but we’re going to tell you anyway. It means Built For Comfort. But as you dig into the BFC W 70, it’ll become clear: Hands Free Entry, CushFit Liner, and Available GripWalk Outsoles. Not to mention, the performance you crave for all-mountain exploration. The BFC W 70 from K2 is an easy-to-ride boot made for all the resort. The comfortable flex makes it very easy to master and you're bound to find your supports quickly, ever more so with the progressive feel offered by the Energy Interlock. The boot is fitted with a very-pleasant CushFit liner designed to let you ride all day long in the greatest comfort. Last but not least, the four hooks let you tighten your boot precisely and you can adjust the velcro strap to get more reactivity if necessary.
