B.F.C. stands for Built for Comfort, and there's no doubt these are a huge step up from the frozen foot lockers you've been using for 20 years. With their medium flex and Powerfuse SpYne, the K2 B.F.C. 100 Heat Ski Boots command your skis with power and precision but really pack a punch in the 'cush' department. The integrated Therm-ic heated liner pulses heat for up to 19 hours so you can say sayonara to icy toes, while the high volume 103 mm last ensures hot spots and pressure points never bother you again.
